DETAILED DESCRIPTION

(8) Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments, it will be understood that the present description is not intended to limit the invention(s) to those exemplary embodiments. On the contrary, the invention(s) is/are intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.

(9) FIG. 1 is a schematic view illustrating an appearance of the interior of a vehicle in which a motion demonstration electronic gear shift apparatus according to various embodiments of the present invention is mounted, FIG. 2 is an exploded view of the motion demonstration electronic gear shift apparatus according to various embodiments of the present invention, and FIG. 3 is a side view of the motion demonstration electronic gear shift apparatus according to various embodiments of the present invention.

(10) As illustrated in FIG. 1, a motion demonstration device 20 according to the present invention may be mechanically operated to be movable forward or rearward on a console surface 10 of a vehicle, or may be electronically operated by being displayed as a digital image on one of a cluster 16, a head up display (HUD), and an Audio, Video, and Navigation (AVN) 18 of the vehicle.

(11) In a case in which the motion demonstration device 20 is mechanically operated, there are advantages that a driver may more intuitively recognize motion of the motion demonstration device and replacement and repair of the motion demonstration device may be simply carried out in comparison with the motion demonstration device that is electronically operated. Hereinafter, the motion demonstration device 20, which is mechanically operated, will be described.

(12) As illustrated in FIG. 2, the motion demonstration device 20 may include a housing 22 which is movably mounted on a console surface 10 of the vehicle and has a space therein, a first bracket 24 which is coupled at an upper side in the housing 22 and supports a gear shift stage selection device 30 and a controller 40, and a second bracket 26 which is coupled at a lower side in the housing 22 and connected with a movable device 50 so as to allow the housing 22 to move.

(13) As the illustrated various embodiments, a user may freely select and replace the housing 22 with a small-scale model of the vehicle purchased by the user or a small-scale model of the vehicle desired by the user, and the gear shift stage selection device 30 is installed at an upper side of the housing 22 so as for the user to change a gear shift stage of the vehicle.

(14) The gear shift stage selection device 30 may be formed in various shapes such as a button type or a horizontal sliding type, and in the exemplary embodiment of the present invention, a button type gear shift stage selection device will be described.

(15) As illustrated in FIG. 2, the gear shift stage selection device includes gear shift buttons 32 which are inserted into a plurality of through holes 22a formed at an upper end of the housing 22, and an elastic member 34 which is attached to lower portions of the gear shift buttons 32 and provides elastic force to the gear shift buttons 32.

(16) A controller 40 is attached to a lower portion of the elastic member 34, and the controller 40 recognizes operations of the gear shift buttons 32 to move the motion demonstration device 20, and transmits a signal generated by the gear shift stage selection device 30 to a transmission control unit (TCU) of the vehicle to change the gear shift stage.

(17) That is, when the driver pushes the gear shift button 32, the gear shift button 32, together with the elastic member 34, is pushed downward to generate a gear shift signal to be transmitted by the controller 40, and thereafter, when the driver releases the gear shift button 32, the gear shift button 32 returns to the original position thereof by elastic force of the elastic member 34.

(18) The first bracket 24 is disposed at a lower side of the controller 40 to support the gear shift stage selection device 30 and the controller 40, and the second bracket 26 is bent in a shape at a lower side of the first bracket 24 and connected with a rod 52 of the movable device.

(19) The movable device 50 serves to move the motion demonstration device 20 forward and rearward by receiving a signal from the controller 40, and may be variously formed as a solenoid, a rectilinear motor, a gear, a link, or the like.

(20) As illustrated in FIGS. 2 and 3, a hollow portion 12 is formed in the console surface 10, the movable device 50 is integrally coupled to a rotary guide 62 disposed below the movable device 50 through the hollow portion 12, and a lower end of the rotary guide 62 is connected to a rotary motor 60.

(21) The rotary motor 60 rotates the rotary guide 62 while rotating based on a steering signal from a steering wheel 14 illustrated in FIG. 1, and the motion demonstration device 20 including the housing 22 is rotated overall clockwise or counterclockwise in accordance with the rotation of the rotary guide 62.

(22) A method of controlling the aforementioned motion demonstration electronic gear shift apparatus according to various embodiments of the present invention will be described in detail below.

(23) FIG. 4 is a flowchart illustrating a method of controlling the motion demonstration electronic gear shift apparatus according to various embodiments of the present invention when a driver operates a stop-stage (P-stage/N-stage) after operating an R-stage, and FIG. 5 is a flowchart illustrating a method of controlling the motion demonstration electronic gear shift apparatus according to various embodiments of the present invention when the driver operates a D-stage after operating the R-stage.

(24) As illustrated in FIG. 4, when an R-stage among the gear shift stages of the vehicle is operated, the controller recognizes the operation of the R-stage first, and transmits information about the R-stage to the movable device (S100).

(25) Therefore, the rod of the movable device is quickly moved rearward (S110), and the motion demonstration device connected with the movable device is quickly moved rearward (S120). In this case, the rearward movement of the motion demonstration device may be carried out within one second.

(26) After the motion demonstration device is moved (S120), an R-stage gear shift signal of the vehicle is transmitted to the TCU by the controller, and the gear shift stage of the vehicle is changed to the R-stage, such that the vehicle travels reversely (S130).

(27) In this case, step S130 of changing the gear shift stage of the vehicle to the R-stage may be carried out after a predetermined time has passed after step S120 of moving the motion demonstration device rearward, the demonstration for a predetermined time allows the driver to perfectly recognize the motion of the motion demonstration device and prevents the driver from erroneously changing the gear shift stage.

(28) When the driver operates a stop-stage (P-stage/N-stage) of the vehicle after the driver stops driving the vehicle, the controller recognizes the operation of the stop-stage first, and transmits information about the stop-stage to the movable device (S200). A P-stage/N-stage gear shift signal recognized by the controller is transmitted to the TCU, and the gear shift stage of the vehicle is changed to the P-stage/N-stage, such that the vehicle is stopped (S210).

(29) In this case, step S210 of changing the gear shift stage of the vehicle to the P-stage/N-stage may be carried out at nearly the same time with or immediately after step S200 of recognizing the operation of the stop-stage (P-stage/N-stage) by the controller.

(30) The reason is that the change of the gear shift stage to the stop-stage (P-stage/N-stage) causes relatively and almost no erroneous gear shift manipulation accident, and in the case of the stop-stage, immediate response is required when the driver operates the stop-stage at the desired time.

(31) After the gear shift stage of the vehicle is changed to the P-stage/N-stage (S210), the rod of the movable device is slowly moved forward (S220), and the motion demonstration device connected with the movable device slowly moves forward and returns to an initial position (S230).

(32) If the driver operates a D-stage among the gear shift stages of the vehicle, the motion demonstration electronic gear shift apparatus according to the present invention is controlled through a process exactly reverse to the aforementioned method of controlling the R-stage.

(33) That is, when the D-stage is operated, the motion demonstration device quickly moves forward, and thereafter, a D-stage gear shift signal is transmitted to the TCU, such that the vehicle travels forward. Then, when the stop-stage (P-stage/N-stage) is operated, a P-stage/N-stage gear shift signal is transmitted to the TCU, such that the vehicle is stopped, and thereafter, the motion demonstration device slowly moves rearward and returns to the initial position.

(34) As illustrated in FIG. 6, when the driver operates the D-stage after operating the R-stage among the gear shift stages of the vehicle, the motion demonstration electronic gear shift apparatus is controlled in accordance with the method of controlling the R-stage as described above, and then controlled in accordance with a method of controlling the D-stage.

(35) That is, the controller 40 recognizes the operation of the R-stage among the gear shift stages of the vehicle first, and transmits information of the R-stage to the movable device (S300), and the rod of the movable device is quickly moved rearward (S310), such that the motion demonstration device connected with the movable device quickly moves rearward (S320).

(36) Next, after a predetermined time has passed, an R-stage gear shift signal of the vehicle is transmitted to the TCU by the controller 40, such that the vehicle travels reversely (S330).

(37) After the reverse traveling of the vehicle is completed by the driver, when the D-stage among the gear shift stages of the vehicle is operated, the controller 40 recognizes the operation of the D-stage and transmits information about the D-stage to the movable device (S400), and the rod of the movable device is quickly moved forward (S410), such that the motion demonstration device connected with the movable device quickly moves forward (S420).

(38) Next, like the operation of the R-stage, a D-stage gear shift signal recognized by the controller 40 is transmitted to the TCU after a predetermined time has passed, and the gear shift stage of the vehicle is changed to the D-stage, such that the vehicle travels forward (S430).

(39) Therefore, even though the driver erroneously changes the gear shift stage by any chance, the driver may directly feel the traveling direction of the vehicle with the hand, and may quickly perform a subsequent manipulation such as a manipulation of immediately pressing a brake pedal or changing the gear shift stage to other stages.

(40) FIG. 6 is a flowchart illustrating a method of controlling the motion demonstration electronic gear shift apparatus according to various embodiments of the present invention.

(41) The motion demonstration electronic gear shift apparatus according to various embodiments of the present invention may be operated in conjunction with a steering operation of the steering wheel 14 of the vehicle, and may perfectly show traveling motion of the vehicle to the driver at the gear shift lever.

(42) As illustrated in FIG. 6, when a steering operation of the steering wheel 14 installed in the vehicle is carried out, a signal is generated by a sensor mounted in motor-driven power steering (MDPS), and the controller 40 recognizes the signal (S500).

(43) The steering signal recognized by the controller 40 is transmitted to the rotary motor coupled to the lower portion of the motion demonstration device such that the rotary motor is operated (S510), and as a result, the motion demonstration device is rotated clockwise or counterclockwise (S520).

(44) Therefore, when the driver turns the vehicle to the right while the driver drives the vehicle, the motion demonstration device is also rotated clockwise, and when the driver turns the vehicle to the left, the motion demonstration device is also rotated counterclockwise, such that the driver may clearly recognize the current rotation direction of the vehicle.

(45) In this case, the rotary motor may rotate the motion demonstration device by rotating immediately after the controller recognizes the steering signal because the driver may be confused at the time of manipulating the steering wheel if the steering signal is delayed.

(46) The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teachings. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and their practical application, to thereby enable others skilled in the art to make and utilize various exemplary embodiments of the present invention, as well as various alternatives and modifications thereof. It is intended that the scope of the invention be defined by the Claims appended hereto and their equivalents.
