[0037] The control device 26 and the driving device 28 may be powered by a vehicle power source such as an internal combustion engine or a battery. Further, the control unit 26 may be communicated with the driving device 28, various sensors and the auxiliary handle 16, via wired connection or wireless connection. The control device 26 may control the auxiliary handle 16 to move from the normal position to the deployed position based on information from one or more sensors. At the deployed position, the auxiliary handle 16 is closer to an interior of the vehicle than at the normal position (i.e., the auxiliary handle 16 is further away from the inner surface 18 of the vehicle door 12). Thus, it is easy for the user to grab the auxiliary handle 16 to open and close the vehicle door or operate the vehicle door.
[0038] The auxiliary handle 16 may be connected to the base 20 and moveable at the deployed position and the normal position relative to the base 20. When the door is at an opening state, the auxiliary handle 16 moves to the deployed position if the user needs an assistance to close the door. As the auxiliary handle 16 is closer to the interior of the vehicle at the deployed position than at the normal position, it is easy for the user to grab the handle to close the door. The auxiliary handle 16 may be moved by the driving device 28 based on instructions or commands from the control device 26 such that the auxiliary handle 16 can automatically switch between the normal position to the deployed position, which is more convenient to the user.
[0039] Referring to
[0040] In some embodiments, the handle assembly 10 may further include a locking sensor 30 to detect a door condition of the vehicle door 12 and communicate with the control device 26. The locking sensor 30 may be disposed on the vehicle door 12 or any other appropriate places of the vehicle. The locking sensor 30 may be a sensor dedicated to the handle assembly 10 or may be a sensor to check the door state and communicate with other control systems of the vehicle. The door locking sensor 30 may send the signal to the control device 26 to indicate that the vehicle door is at the opening state. The control device 26 may control the auxiliary handle 16 to move to the deployed position when receive the information that the door is opened. When the vehicle door 12 is closed, there is no need for the auxiliary handle 16. The auxiliary handle 16 may be driven to the normal position on the base 20 such that the auxiliary handle 16 will not take a space in the interior of the vehicle. In some embodiments, when the locking sensor 30 detects that that the door condition is changed from an unlocked state (i.e., an open state) to a locked state (i.e., a closed state), the control device 26 controls the auxiliary handle 16 to move to the normal position from the deployed position. In one example, the control device 26 may control the auxiliary handle 16 to move to the normal position from the deployed position based on the door condition and other information. For example, the control device 26 may issue a command to move the auxiliary handle 16 back to the normal position when it is determined that the door is closed and the auxiliary handle 16 has been in the deployed position for a predetermined time.
[0041] It should be understood that the action of restoring the auxiliary handle 16 to the normal position or deploying the auxiliary handle 16 may be activated by other operation components such as buttons disposed on the vehicle door 12 or a center console. Alternatively, the auxiliary handle 16 may be restored or deployed manually by the user.
[0042] The handle assembly 10 may further include a detection unit 32 to detect user information, and send a signal to the control device 26. In some embodiments, the detection unit 32 is configured to send the signal to activate the auxiliary handle 16 when it detects that a predetermined condition is met. In some embodiments, the control device 26 receives the user information from the detection unit 32 and determine whether to deploy or restore the auxiliary handle 16.
[0043] In some embodiments, the user information includes whether a user occupies or sits on a seat. In one embodiment, the detection unit 32 includes a sensor to detect occupancy of a seat. The sensor sends a signal when it detects a driver or a passenger sits on the seat. In some embodiment, when the control device 26 receives a signal that the seat is occupied from the detection unit 32 and a signal that the vehicle door 12 is open from the door locking sensor 30, the control device 26 may control the drive device 28 to move the auxiliary handle 16 to the deployed position. Subsequently, when the control device 26 receives the signal that the door is closed or is changed from an open state to a closed state, the control device 26 may control the drive device 28 to move the auxiliary handle 16 to the normal position.
[0044] In some embodiments, the user information may include information to a stature of a user. The detection unit 32 may include a sensor to detect information related to the user stature. The control unit 26 may store various threshold values such as a threshold pressure of a seat, a threshold of occupied area of a seat or a threshold mass. For example, the detection unit may a sensor such as a weight sensor or a pressure sensor to detect a weight, a pressure applied to the seat by a user and an occupied area of the user on the seat. Such user information may correlate with a stature of the user. The control device 26 may receive the user information from the weight sensor, the pressure sensor, or other sensors compare them with threshold values to determine whether the auxiliary handle 16 needs to be activated. For example, the control device 26 may determine that the user can reach the base handle 14 easily and there is no need to actuate the auxiliary handle 16 when the user information indicates that the user has a large stature. The control device 26 may determine that the user has difficult to reach the base handle 14 and the auxiliary handle 16 needs to be deployed when the user information indicates that the user has a small stature. In some embodiments, some conditions need to be met for deployment of the auxiliary handle 16. The pressure sensor or the weight sensor may be disposed in a seat cushion. It should be understood that the sensor may be any appropriate sensors to detect the user information and may be disposed at any positions of the seat such as, disposed in a seat cushion, a seatback or a headrest of the seat because the sensor detects the condition or the change of the condition of the seat. It further should be understood that the position and type of the sensors do not constitute any limits to the invention. Further, the control device 26 may communicate with an occupant classification system of the vehicle to obtain the user information.
[0045] In some embodiments, the control device 26 may communicate with a mobile terminal such as a smart phone held by the user to adjust the auxiliary handle 16 to a position preferred for the user. It should be understood that adjustment of the auxiliary handle 16 may be performed before or after the user enters the vehicle. In some embodiments, the handheld devices or mobile terminals communicated with the vehicle may be used as the detection unit 32. The handheld device is independent from the vehicle, and contain the user identification. Under some situations, when remotely starting a vehicle with a handheld device, the control device 26 receives the user identification and obtain the information related to the user stature and control the auxiliary handle 16 accordingly.
[0046] In some embodiments, the detection unit 32 may include an image sensor disposed in an interior of the vehicle. For example, the image sensor may be a surveillance camera or a vision sensor such as a retina sensor to identify the user. In some embodiments, the detection unit 32 may be a fingerprint detector or a hand palm detector which is configured to identify the user. When the image sensor, the finger detector or the hand palm detector detects that a user has entered the vehicle and sit on the seat, the information is sent to the control device 26.
[0047] In some embodiments, the control device 26 may store reference data or images. When the control device 26 receives the captured image of a user by the image sensor such as a surveillance camera or a vision sensor (e.g., a retina detector), it compares the captured image with the reference images. When a stature or a ratio of the captured image is bigger than the reference image, the control device 26 may determine that the user may have a large stature and further determine that the auxiliary handle 16 does not need to be actuated. If the stature or the ratio of the captured image is smaller than the reference image, the control device 26 may determine that the user has a relative small stature, and the auxiliary handle 16 needs to be deployed to assist the user.
[0048] Similarly, for the handle assembly including a detection unit 32 such as a vision sensor, a retina detector, a fingerprint detector, or a hand palm detector, the user information may be stored in the control device 26 or a vehicle control system. For example, the information of a first user with a larger stature and a second user with a smaller stature are stored in a look up table of the control device 26 or the vehicle control system. When the first user enters the vehicle, the detection device detects the user's image, retina, fingerprint, or hand and the control device 26 searches the look up table. When match information is found, the control device 26 may determine that the first user does not need the auxiliary handle 16 to be deployed for assistance. When the second user enters the vehicle, the detection device detects the user's image, retina, fingerprint, or handprint and the control device 26 searches the look up table. When match information is found, the control device 26 may determine that the second user needs the auxiliary handle 16 to be deployed for assistance.
[0049] It should be understood that the detection unit 32 is not limited to the embodiments described above. In other words, the detection unit 32 maybe any device that detects the user information, and send the information to the control device 26 such that the control device can determine how to operate the auxiliary handle 16. It also should be understood that all embodiments described above or below may be combined to form new embodiment. For example, the seat of the vehicle may include various sensors. An image sensor or a haptic detector may be disposed inside the vehicle to determine the user information.
[0050] The control device 26 can control the auxiliary handle 16 automatically to deploy or retract. Further the control of the auxiliary handle 26 may be operated by the control device 26 based on the information from the detection unit 32 and/or the locking sensor 30. In this way, an automation is achieved via interaction of the control device 26, the locking sensor 30, the detection unit 32 and the drive device 28 such that the user does not need to operate the handle manually.
[0051] Additionally or alternatively, in one embodiment, the detection unit 32 may include a proximation sensor disposed on the base handle 14 or the auxiliary handle 16. In one embodiment, when a user sits on the seat and reaches out his/her arm toward the base handle 14, the proximation sensor may detect a distance between the arm and the base handle 14. If the distance is less than the predetermined threshold, the control device 26 may determine that the user can reach the base handle 14. If the distance is greater than the predetermined value, the control device 26 may determine that the user may not be able to reach the base handle 14 and the auxiliary handle 16 needs to be deployed to assist the user. In some embodiments, the control device 26 may be configured to deploy the auxiliary handle 16 from the normal position once the proximation sensor detects the user's arm reaches out toward the base handle 14. In some embodiments, the auxiliary handle 16 may be deployed when the proximation sensor detects that the arm keeps a distance with the handle 14 in a certain time (such as 1 second or another proper period time). When a threshold time value is exceeded, the control device 26 may determine that the user has a difficult to reach the base handle 14, and an assistance needs to be provided.
[0052] Continuing with
[0053] In some embodiments, the actuator 22 may be a button disposed at any appropriate positions. For example, the actuator 22 may be disposed in an interior of the vehicle, such as an instrument panel, a center console, or a vehicle door. The actuator 22 may also be integrated on a smart key of the vehicle. In some embodiments, the actuator 22 may be an audio unit to receive a voice or instructions from a user. The control device 26 may be configured to recognize the voice or the instruction and control the driving device 28 accordingly. In some embodiments, the actuator 22 may be an image sensor configured to capture a hand gesture. The control device 26 may be configured to recognize the hand gesture and control the driving device 28 accordingly. Referring to
[0054]
[0055] The auxiliary handle 116 may further be connected a drive device 28. In some embodiments, the drive device 28 is a motor. Upon a command from a control device, the driving device 28 rotates the auxiliary handle 116 from a normal position as shown in
[0056]
[0057] The legs 240 are driven by a driving device 28 such that the auxiliary handle 216 can extend and retract between a deployed position as shown in
[0058] In some embodiments, the auxiliary handle 14, 114, 214 may further be configured to maintain different deployed positions. For example, the auxiliary handle 14, 114 and 214 may be configured to move between a normal position, a first deployed position, and a second deployed position between the first deployed position and the normal position. As the users have different statures or different habits of grabbing the handle, the handle assembly may be configured to provide different deployed positions. The driving device 28 may include a step motor to drive the auxiliary handle to different deployed position and return to the normal position.
[0059] Turning back to
[0060]
[0061] At 306, the method 300 may include actuating the auxiliary handle to move the auxiliary handle to a deployed position or to a normal position based on one of detected door condition and detected user information. The method 300 may actuating the auxiliary handle to move the auxiliary handle to the deployed position when it determines that the door is opened based on a signal from a locking sensor. In another example, the method 300 may include actuating the auxiliary handle to move the auxiliary handle to the deployed position when it determines that the door is open and a user has sit on a seat corresponding to the auxiliary handle. In another example, the method 300 may include actuating the auxiliary handle to move the auxiliary handle from the deployed position to the normal position when it determines that the door is locked and a user has sit on the seat corresponding to the auxiliary handle. In another example, the method 300 may actuate the auxiliary handle based on detected hand movement of the user.
[0062] In yet another example, the method 300 may actuating the auxiliary handle when it determines that a user has a small stature based on information from the detection unit.
[0063] The handle assembly of a vehicle according to one or more embodiment of the present disclosure activates an auxiliary handle based on one of the door condition and the user information. Thus, the auxiliary handle can be used based on the need of the user.
