The spring and the shock absorber 38 may be integrally formed. A component in which the spring and the shock absorber 38 are integrally formed is also referred to as a coil over, for example. The suspension 36 may be an axle suspension system (rigid type) in which the wheels on the right and left sides are integrally moved, or may also be an independent suspension system (independent type) in which the wheels on the right and left sides are independently moved. When the vehicle 10 is an off-road vehicle, the suspension 36 is preferably the independent suspension system.

(37) The independent suspension system may be any of various types of suspension systems such as a double wishbone system, a strut system, a multilink system, or a trailing-arm system. The double wishbone system includes an upper arm and a lower arm pivotable around a wheel hub as the suspension arm 37. The strut system includes a lower arm as the suspension arm 37 and does not include an upper arm. The multilink system includes one or more arms in addition to an upper arm and a lower arm as the suspension arm 37. The trailing-arm system includes a swing arm including a swing axis (pivot). The swing arm is rigidly connected to a wheel hub.

(38) The same suspension system may be adopted to the suspension 36 of the front wheels 30F and the suspension 36 of the rear wheels 30R. Different suspension systems may be adopted to the suspension 36 of the front wheels 30F and the suspension 36 of the rear wheels 30R. For example, it is applicable that the suspension 36 of the front wheels 30F is the double wishbone system and the suspension 36 of the rear wheels 30R is the trailing-arm system.

(39) The suspension 36 may be an active suspension or a passive suspension. The active suspension is a suspension which can control damping force by hydraulic pressure or pneumatic pressure, for example. In this case, the vehicle 10 includes a control apparatus electrically controlling the active suspension. The active suspension may be a hydraulic pressure active suspension provided with a hydraulic pressure actuator in which hydraulic pressure can be adjusted as a shock absorber, or may also be an air suspension provided with an air chamber in which pneumatic pressure can be adjusted as a spring, for example. The passive suspension is a suspension which does not include a mechanism which can control damping force by hydraulic pressure or pneumatic pressure, for example.

(40) A control system of the active suspension may be semi-active control or full-active control. In the semi-active control, only damping force while the vehicle is traveling is controlled. In the full-active control, a vehicle body height while the vehicle is stopping is controlled in addition to the damping force while the vehicle is traveling. The active suspension on which the full-active control can be performed functions as a vehicle body height adjustment apparatus. A control apparatus in which the full-active control is performed on the active suspension functions as a control apparatus controlling the vehicle body height adjustment apparatus. In the present embodiment, the suspension is the active suspension on which the full-active control can be performed.

(41) The vehicle 10 includes an electronic control unit (ECU) 39 as the control apparatus, for example. The ECU 39 controls each apparatus in the vehicle 10.

(68) The under-hatch component 32 may include a maintenance target component, for example. The maintenance target component is a component which requires regular maintenance or a component which has a high maintenance frequency, for example. For example, the component relating to the travel mechanism such as the travel drive source 32, the oil filter, the battery, and the air cleaner described above is considered the maintenance target component. It is easy to have access to the maintenance target component, thus maintenance properties of the maintenance target component are improved. It is sufficient that a maintenance target part of the maintenance target component is provided in an accessible position through the opening part 19.

(69) When the under-hatch component 32 includes the maintenance target component, it is applicable that the rack 50 can retract to a position which does not interfere with a maintenance operation of the maintenance target component, or can be detached from the vehicle body 11.

(70) The under-hatch component 32 may include a plurality of components. A component having high design properties in the plurality of components may be provided in a position exposed more easily than a component having low design properties. A component having high maintenance properties in the plurality of components may be provided in a position exposed more easily than a component having low maintenance properties.

(71) The under-hatch component 32 may be exposed from a position other than the opening part 19. For example, the under-hatch component 32 may be exposed from a position between the lower part of the rear sidewall part 18D and the chassis 20.

(72) <Control of Vehicle Body Height>

(73) FIG. 8 is a block diagram illustrating an apparatus configuration of the vehicle 10.

(74) The vehicle 10 includes a hatch sensor 48, a rack sensor 58, a vehicle body height adjustment apparatus 36, and a control apparatus 39. The hatch sensor 48 detects rotation of the hatch 40. The rack sensor 58 may detect rotation of the rack 50. The rack sensor 58 may detect inclination of the rack 50 with respect to the vehicle body 11 or horizon. The rack sensor 58 may include a sensor detecting the rotation of the rack 50 and a sensor detecting the inclination of the rack 50 with respect to the vehicle body 11 or horizon. The vehicle body height adjustment apparatus 36 adjusts a height of the vehicle body 11. The control apparatus 39 controls the vehicle body height adjustment apparatus 36. Herein, the active suspension 36 described above functions as the vehicle body height adjustment apparatus 36. The vehicle body height adjustment apparatus 36 may be made as a mechanism different from the suspension 36. Herein, the ECU 39 functions as the control apparatus 39 controlling the vehicle body height adjustment apparatus 36.

(75) A detection result of the hatch sensor 48 and a detection result of the rack sensor 58 are transmitted to the ECU 39. The ECU 39 controls the vehicle body height adjustment apparatus 36 based on the detection result of the hatch sensor 48 and/or the detection result of the rack sensor 58. The vehicle body height adjustment apparatus 36 is a hydraulic type apparatus or a pneumatic type apparatus, and the vehicle body 11 can be moved up and down by adjusting hydraulic pressure or pneumatic pressure. Herein, the active suspension 36 provided to each of four wheels functions as the vehicle body height adjustment apparatus 36. Accordingly, the vehicle body 11 can be moved up and down independently in a position corresponding to each of four wheels regardless of the other position.

(76) The vehicle body height adjustment may be inclination of the vehicle body 11 or moving up and down of the vehicle body 11 in a horizontal posture without inclination thereof. When the vehicle body 11 is inclined, the vehicle body 11 may be inclined so that heights of the front part and the rear part are different from each other. In this case, when the rear part is lower in height than the front part, the stored object 60 can be taken in and out from the rack 50. When the vehicle body 11 is inclined, the vehicle body 11 may be inclined in a rolling direction. That is to say, the vehicle body 11 may be inclined so that heights of a right part and a left part of the vehicle 10 are different from each other. In this case, the under-hatch component 32 can be easily seen.

(77) FIG. 9 is a flow chart illustrating an example of a control operation of the ECU 39. In the example illustrated in FIG. 9, the ECU 39 controls the vehicle body height adjustment apparatus 36 based on both a state of the hatch 40 and a state of the rack 50.

(78) In Step S11, the ECU 39 determines whether the open-close state of the hatch 40 is changed based on the detection result of the hatch sensor 48. When it is determined that the open-close state of the hatch 40 is changed, the process proceeds to Step S12.

(79) In Step S12, the ECU 39 determines whether the open-close state of the rack 50 is changed based on the detection result of the rack sensor 58. When it is determined that the open-close state of the rack 50 is changed, the process proceeds to Step S13.

(80) In Step S13, the ECU 39 controls the vehicle body height adjustment apparatus 36 to change the vehicle body height. The changed vehicle body height is preset based on the state of the hatch 40 or the state of the rack 50.

(81) For example, when it is determined in Step S11 and Step S12 that both the hatch 40 and the rack 50 are changed in the opening direction, the ECU 39 may control the vehicle body height adjustment apparatus 36 so that the vehicle body height gets lower in Step S13. For example, when it is determined in Step S11 and Step S12 that both the hatch 40 and the rack 50 are changed in a closing direction, the ECU 39 may control the vehicle body height adjustment apparatus 36 so that the vehicle body height gets higher in Step S13.

(82) FIG. 10 is a side view illustrating the vehicle 10 in which the vehicle body height is adjusted. FIG. 10 illustrates an example indicating an adjustment result of the vehicle body height in a case where it is determined that both the hatch 40 and the rack 50 are changed in the opening direction in Step S11 and Step S12.

(83) In the example illustrated in FIG. 10, the suspension 36 in the front part of the vehicle body 11 extends in a direction of an arrow mark A1, and the suspension 36 in the rear part of the vehicle body 11 shrinks in a direction of an arrow mark A2. Accordingly, the vehicle body height is adjusted so that the front part is moved up and the rear part is moved down. The rear part of the vehicle body 11 where the rack 50 and the under-hatch component 32 are located is moved down, thus it is easy to have access to the stored object 60 mounted to the rack 50 or the under-hatch component 32. The opening part 19 is also moved down, thus the under-hatch component 32 can be easily observed through the opening part 19.

(84) For example, when it is determined in Step S11 and Step S12 that both the hatch 40 and the rack 50 are changed in the closing direction, the ECU 39 may change the vehicle body height from the state in FIG. 10 to the state in FIG. 1.

(85) FIG. 11 is a flow chart illustrating another example of the control operation of the ECU 39. In the example illustrated in FIG. 11, the ECU 39 controls the vehicle body height adjustment apparatus 36 based on the state of the hatch 40.

(86) In Step S21, the ECU 39 determines whether the open-close state of the hatch 40 is changed based on the detection result of the hatch sensor 48. When it is determined that the open-close state of the hatch 40 is changed, the process proceeds to Step S22.

(87) In Step S22, the ECU 39 controls the vehicle body height adjustment apparatus 36 to change the vehicle body height. The change of the vehicle body height in Step S22 may be any change described in Step S13. The control apparatus may lower the height of the vehicle body 11 upon determining that the hatch 40 is opened.

(88) FIG. 12 is a flow chart illustrating still another example of the control operation of the ECU 39. In the example illustrated in FIG. 12, the ECU 39 controls the vehicle body height adjustment apparatus 36 based on the state of the rack 50.

(89) In Step S31, the ECU 39 determines whether the open-close state of the rack 50 is changed based on the detection result of the rack sensor 58. When it is determined that the open-close state of the rack 50 is changed, the process proceeds to Step S32.

(90) In Step S32, the ECU 39 controls the vehicle body height adjustment apparatus 36 to change the vehicle body height. The change of the vehicle body height in Step S32 may be any change described in Step S13. The control apparatus may lower the height of the vehicle body 11 upon determining that the rack 50 is inclined with respect to the vehicle body 11.

(91) The control apparatus may adjust the vehicle body height based on the state of the vehicle 10 regarding the rack 50. The state of the vehicle 10 regarding the rack 50 may include any one or some of the opening of the rack 50, the opening of the hatch 40, and the inclination of the rack 50. Applicable as the adjustment of the vehicle body height is not only the case where the stored object 60 can be easily taken in and out but also a case where the posture of the rack 50 is set to get close to the horizontal posture so that the stored object 60 does not drop out even when the vehicle body 11 is inclined due to a concave-convex shape of a road surface.

(92) <Lock Control of Rack 50>

(93) FIG. 13 is a block diagram illustrating an apparatus configuration of the vehicle 10.

(94) The vehicle 10 includes the hatch sensor 48 described above, a rack lock 56, and the control apparatus 39. The hatch sensor 48 detects the rotation of the hatch 40 (release state of the hatch 40). The rack lock 56 is configured to be able to switch lock and lock release of the rack 50. For example, a position of the rack 50 where the lock and lock release are performed on the rack lock 56 may be the first position, the second position, and an intermediate position between the first position and the second position. The control apparatus 39 controls the rack lock 56. Herein, the ECU 39 described above functions as the control apparatus 39 controlling the rack lock 56.

(95) A detection result of the hatch sensor 48 is transmitted to the ECU 39. The ECU 39 switches lock and lock release of the rack lock 56 based on the detection result of the hatch sensor 48. For example, the ECU 39 releases the rack lock 56 to allow the rack 50 to move from the first position to the second position upon determining the release state of the hatch 40.

(96) FIG. 14 is a plan view illustrating the lock/release state of the rack lock 56.

(97) As illustrated in FIG. 14, the rack lock 56 includes a latch 56A, a striker 56B, and a pivoting part 56C. One of the latch 56A and the striker 56B is provided to the rack body 51, and the other one thereof is provided to a side of the vehicle body 11. The other one thereof may be provided to the partition wall 22, or may also be provided to the ROPS 12, for example. The pivoting part 56C pivots the latch 56A in a direction of an arrow mark A3. Accordingly, the state of the latch 56A is changed between a state of being locked to the striker 56B and a state of being detached from the striker 56B. The pivoting part 56C is a motor, for example.

(98) FIG. 15 is a flow chart illustrating an example of a control operation of the ECU 39.

(99) In Step S41, the ECU 39 determines whether the hatch 40 is opened based on the detection result of the hatch sensor 48. When it is determined that the hatch 40 is opened, the process proceeds to Step S42.

(100) In Step S42, the ECU 39 controls the rack lock 56 and releases the rack lock 56. Accordingly, the rack 50 can be moved from the first position to the second position.

(101) The vehicle 10 may include a load sensor detecting a load of the stored object 60 in the rack 50. The ECU 39 may perform control so that the rack lock 56 is kept in the lock state when the load sensor detects the load of the stored object 60 in the rack 50, and the lock of the rack lock 56 is released when the load sensor does not detect the load of the stored object 60 in the rack 50. Accordingly, dropping of the stored object 60 can be suppressed when the rack 50 is rotated.

(102) The vehicle 10 may include a sensor detecting an attachment state of the fixing component 52 in addition to the load sensor. In this case, when the load sensor detects the load of the stored object 60 in the rack 50 and also detects that the fixing component 52 is not attached, the ECU 39 may control so that the rack lock 56 is kept in the lock state. The ECU 39 may perform control so that the lock of the rack lock 56 is released when the load sensor does not detect the load of the stored object 60 in the rack 50. The ECU 39 may perform control so that the lock of the rack lock 56 is released when the load sensor detects the load of the stored object 60 in the rack 50 and also detects that the fixing component 52 is attached. Accordingly, the rack 50 can be rotated more safely when the spare tire 60 is mounted to the tire rack 50 described above, for example.

(103) <Operating Element 55>

(104) FIG. 16 is a side view illustrating a modification example of a position of the operating element 55. As illustrated in FIG. 16, the operating element 55 performing the open-close operation on the rack 50 may be located on an upper side of the rear wheels 30R.

(114) The hatch hinge 42 is located in a front end of the hatch body 41, and the rack hinge 53 is located in the rear end of the rack body 51. The hatch 40 and the rack 50 can be rotated in directions opposite to each other, thus hardly interfere with each other compared with a case where they are rotated in the same direction.

(115) The hatch 40 is moved to the upper position beyond the pivot range of the rack 50 while the opening part 19 is released. Thus, the interference between the hatch 40 and the rack 50 is prevented, and the rack 50 can be sufficiently inclined.

(116) The vehicle body 11 includes the partition wall 22 partitioning the luggage space in which the rack 50 is provided and the occupant space in which the seat 26 is provided. Accordingly, transfer of heat between the luggage space and the occupant space can be suppressed.

(117) The rack 50 is the tire rack 50 to which the spare tire 60 is mounted. The tire rack 50 can cover the under-hatch component 32.

(118) The tire rack 50 can be moved between the first position and the second position while the spare tire 60 is mounted thereto. The spare tire 60 can be mounted to and taken out from the tire rack 50 in the second position, thus the spare tire 60 can be easily mounted and taken out.

(119) The vehicle 10 includes the vehicle body height adjustment apparatus 36 adjusting the height of the vehicle body 11, and detects the rotation of the hatch 40, thus the vehicle body height adjustment apparatus 36 adjusts the height of the vehicle body 11. Accordingly, the vehicle body height can be automatically changed when the hatch 40 is rotated.

(120) The vehicle 10 includes the operating element 55 performing the open-close operation on the rack 50, and the operating element 55 is located inside the vehicle 10 with respect to the hatch 40 in the close state. Suppressed accordingly is the operation of the operating element 55 while the hatch 40 is not opened.

(121) The operating element 55 performing the open-close operation on the rack 50 is located on the upper side of the rear wheels 30R in the vehicle 110. Accordingly, the operating element 55 can be operated even when the user does not approach the lateral side of the vehicle 10.

(127) The vehicle 10 includes the hatch sensor 48 determining the release state of the hatch 40 and the rack lock 56 allowing the rack 50 to move from the first position to the second position when the sensor 48 determines the release state of the hatch 40. Accordingly, movement of the rack 50 from the first position to the second position can be suppressed while the hatch 40 is in the close state.

(128) The control apparatus may control the vehicle body height adjustment apparatus 36 based on the state of the vehicle 10 regarding the rack 50 to adjust the height of the vehicle body 11. In this case, the vehicle body height adjustment apparatus 36 is controlled based on the state of the vehicle 10 regarding the rack 50 and the height of the vehicle body 11 is adjusted, thus the stored object 60 can be easily taken in and out from the rack 50, and can be stored in an appropriate state in the rack 50.

(129) The control apparatus 39 may lower the height of the vehicle body 11 upon determining that the rack 50 is inclined with respect to the vehicle body 11. Accordingly, movement of the rack 50 from the first position to the second position can be suppressed while the hatch 40 is in the close state.
