DETAILED DESCRIPTION

[0039] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0040] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0041] The following combination Figures 1-6 The lifting system 10 for the vehicle 1000 , the suspension system 100 of the vehicle 1000 , the vehicle 1000 , and the control method of the vehicle 1000 according to the embodiments of the present application are described in detail.

[0042] Reference Figure 1 As shown, the lifting system 10 for the vehicle 1000 according to the embodiment of the present application includes: a lifting module 13 , a first driving device 4 and a locking module 56 .

[0043] The lifting module 13 is adapted to connect to the vehicle body, and the first drive device 4 is used to drive the lifting module up and down. The lifting module 13, the first drive device 4, and the locking module 56 are configured such that, when a side collision risk is determined, the first drive device 4 drives the lifting module 13 to move the vehicle body upward, and the locking module 56 locks the lifting module 13 in a target position, thereby locking the vehicle body in the target position.

[0044] When another vehicle approaches the vehicle, the lift system 10 of the vehicle can lift the corresponding side of the vehicle body. Specifically, the first drive device 4 drives the lift module 13 upward, and the lifting module 13 raises the corresponding side of the vehicle body. This can reduce personal injury to the occupants of the vehicle 1000 if the other vehicle collides with the vehicle. Furthermore, when the lift module 13 rises to a certain height, the locking module 56 can lock the lift module 13, locking the vehicle body in the target position and preventing the corresponding side of the vehicle body from descending, effectively preventing secondary injury to the occupants caused by changes in the vehicle body height.

[0045] According to the lifting system 10 for the vehicle 1000 according to the embodiment of the present application, the body of the vehicle 1000 can be lifted, so that when other vehicles approach the vehicle from the side, the lifting system 10 can lift the corresponding side of the body, thereby reducing personal injury to the occupants of the vehicle when other vehicles collide with the vehicle from the side. By using the locking module 56 to lock the lifting module 13 in the target position, it can effectively prevent the change in the body height from causing secondary injury to the occupants in the vehicle.

[0046] In some embodiments of the present application, the target position is determined based on vehicle information from an oncoming vehicle. Specifically, different vehicle information corresponds to different target positions. Thus, the vehicle body can be lifted to the target position corresponding to each oncoming vehicle, thereby better protecting the vehicle occupants.

[0047] In some embodiments of the present application, the vehicle information includes vehicle model information and / or front bumper position information. Specifically, the vehicle information can be vehicle model information, front bumper position information, or both.

[0048] In some embodiments, a camera installed on the vehicle is used to capture images of vehicles coming from the side, and the type of the vehicle coming from the side can be determined by analyzing the images.

[0049] In some embodiments, a camera installed on the vehicle is used to capture images of a vehicle coming from the side. By analyzing the images, the height of the front bumper of the vehicle coming from the side, that is, the position information of the front bumper, can be determined.

[0050] In some embodiments of the present application, the target position is: different vehicle models correspond to different target positions, and / or different front bumper position information corresponds to different target positions.

[0051] Optionally, different target positions are different positions in the height direction of the vehicle 1000 .

[0052] Specifically, the larger the vehicle type, the higher the target position to which the vehicle body needs to be lifted. For example, the vehicle type can be a sedan, SUV, off-road vehicle, etc., and the target position to which the vehicle body needs to be lifted is determined based on the vehicle type. Optionally, when the oncoming vehicle is an off-road vehicle, the target position to which the vehicle body needs to be lifted by the vehicle lifting module 13 is higher than when the oncoming vehicle is an SUV, and when the oncoming vehicle is an SUV, the target position to which the vehicle body needs to be lifted is higher than when the oncoming vehicle is a sedan. In this way, the vehicle body can be lifted to the target position corresponding to the different models of the oncoming vehicle, thereby better protecting the occupants of the vehicle.

[0053] Similarly, the higher the front bumper position of the oncoming vehicle, the higher the target position of the vehicle body needs to be lifted. In this way, according to the different front bumper positions of the oncoming vehicle, the vehicle body can be lifted to the target position corresponding to the oncoming vehicle, so as to better protect the occupants in the vehicle.

[0054] In some embodiments of the present application, reference is made to Figure 1 As shown, the locking module 56 includes a locking member 5 and a second driving device 6. The second driving device 6 is used to drive the locking member 5. The locking member 5 has a locked position and an unlocked position. When the locking member 5 is in the locked position, the locking member 5 is used to lock the lifting module 13. When the locking member 5 is in the unlocked position, the locking member 5 is used to unlock the lifting module 13. The second driving device 6 is used to drive the locking member 5 to switch between the locked and unlocked positions.

[0055] When a side collision risk is determined for vehicle 1000, second drive device 6 is configured to actuate locking member 5 to a locked position, locking lift module 13 in a target position. This locks the vehicle body in the target position, preventing the side of the vehicle from lowering and effectively preventing secondary injuries to vehicle occupants caused by changes in vehicle height.

[0056] In some embodiments of the present application, the lifting module 13, the first drive device 4, the second drive device 6, and the locking member 5 are configured such that, when it is determined that the vehicle 1000 is at risk of a side collision, the first drive device 4 drives the lifting module 13 to the first position, and the second drive device 6 drives the locking member 5 to the locked position, so that the lifting module 13 is locked in the target position. Specifically, after the lifting system 10 receives the lifting and locking signal, the first drive device 4 drives the lifting module 13 upward until the lifting module 13 reaches the first position. The second drive device 6 then drives the locking member 5 to the locked position, and the lifting module 13 moves downward to a position where the locking member 5 supports the lifting module 13. At this point, the lifting module 13 is locked in the target position.

[0057] That is to say, when the vehicle body needs to be lifted, the control system of the vehicle 1000 sends a lifting and locking signal to the lifting system 10, and the lifting module 13 rises. When the lifting module 13 rises to the first position, the locking part 5 first moves to the locking position. At this time, there is a gap between the lifting module 13 and the locking part 5. Then the lifting module 13 is moved downward until the gap between the lifting module 13 and the locking part 5 is reduced to zero. The lifting module 13 is supported by the locking part 5, and the lifting module 13 cannot continue to move downward. The side of the vehicle body remains in a lifted state.

[0058] In some embodiments, during the period from when the locking member 5 moves to the locking position to when the lifting module 13 is in contact with the locking member 5 , the downward movement of the lifting module 13 can be achieved by the vehicle body pushing the lifting module 13 downward under the action of gravity, and no longer relies on the active drive of the first drive device 4 .

[0059] In other embodiments, during the period from when the locking member 5 moves to the locking position to when the lifting module 13 is in contact with the locking member 5 , the downward movement of the lifting module 13 can be driven actively by the first driving device 4 .

[0060] In some embodiments of the present application, the lifting module 13, the first drive device 4, the second drive device 6, and the locking member 5 are configured such that: when the locking member 5 locks the lifting module in the target position and it is determined that the vehicle 1000 does not face a side collision risk, the first drive device 4 drives the lifting module 13 to the transition position, the second drive device 6 drives the locking member 5 to the unlocked position, and the first drive device 4 drives the lifting module 13 to the second position. When the side collision risk is eliminated, the locking member 5 is unlocked, allowing the lifting module 13 connected to the side body to descend to the second position, thereby driving the side body to descend.

[0061] Specifically, after the lifting system 10 receives the release signal, the first drive device 4 drives the lifting module 13 to rise to the transition position, the second drive device 6 drives the locking member 5 to move to the unlocking position, and the first drive device 4 drives the lifting module 13 to descend until the lifting module 13 reaches the second position.

[0062] That is, when the vehicle body is no longer required to be lifted, the control system of vehicle 1000 sends a release signal to lift system 10. Upon receiving the release signal, lift module 13 rises to the transition position, while locking member 5 remains in the locked position. Thus, lift module 13 and locking member 5 separate, and then locking member 5 moves to the unlocked position. Next, first drive device 4 drives lift module 13 downward. Since locking member 5 has returned to the unlocked position, it no longer blocks downward movement of lift module 13 until lift module 13 reaches the second position. When lift module 13 is in the second position, the vehicle body on that side is at a normal height and is not lifted.

[0063] In some embodiments of the present application, the transition position is located between the first position and the second position, or the first position is located between the transition position and the second position. In this way, the transition position and the first position are different positions, and a position sensor is respectively provided at the transition position, the first position, and the second position for detecting different positions of the lifting module 13.

[0064] Or in some other embodiments of the present application, the transition position and the first position are the same position. In this way, by providing a position sensor at the transition position and the first position, the transition position and the first position can be detected at the same time, which can save the number of sensors. In some embodiments of the present application, the second drive device 6 is configured as follows: when it is determined that the vehicle 1000 is at risk of side collision, the second drive device 6 is used to drive the locking member 5 to move along the first direction to the locking position, so that the lifting module 13 is locked at the target position; when the locking member 5 locks the lifting module 13 at the target position, and it is determined that the vehicle 1000 is not at risk of side collision, the second drive device 6 is used to drive the locking member 5 to move along the second direction to the unlocking position, wherein the first direction is opposite to the second direction. For example, in Figure 1 In the embodiment shown, the first direction is Figure 1 The F3 direction shown, the second direction is Figure 1 In the F4 direction shown, the lifting module 13 is raised and lowered along the F1-F2 direction, wherein the F1-F2 direction and the F3-F4 direction are different directions. In this way, the movement of the lifting module 13 and the movement of the locking member 5 are unlikely to interfere with each other. Optionally, the F1-F2 direction and the F3-F4 direction can be perpendicular or at an acute angle.

[0065] In some embodiments of the present application, reference is made to Figure 1 As shown, the second driving device 6 includes: an electromagnetic component 61. When it is determined that the vehicle 1000 has a risk of side collision, a first current flowing to the electromagnetic component 61 generates a force to drive the locking component 5 to move along a first direction to a locking position, so that the lifting module 13 is locked at the target position; when the locking component 5 locks the lifting module 13 at the target position and it is determined that the vehicle 1000 has no risk of side collision, a second current flowing to the electromagnetic component 61 generates a force to drive the locking component 5 to move along a second direction to an unlocking position, wherein the directions of the first current and the second current are opposite.

[0066] In some embodiments of the present application, reference is made to Figure 1As shown, the second drive device 6 includes an electromagnetic component 61 and an elastic element 62. When it is determined that the vehicle 1000 is at risk of a side collision, the electromagnetic component 61 is energized to generate a force that drives the locking component 5 to move in a first direction to a locked position, so that the lifting module 13 is locked in the target position. When the locking component 5 locks the lifting module 13 in the target position and it is determined that the vehicle 1000 is not at risk of a side collision, the electromagnetic component 61 is de-energized, and the force generated by the elastic element 62 drives the locking component 5 to move in a second direction to an unlocked position, wherein the first direction is opposite to the second direction. In other words, the elastic element 62 is used to apply a return force to the locking component 5 to move toward the unlocked position. By providing the electromagnetic component 61 and the elastic element 62 to control the position of the locking component 5, the locking and unlocking actions of the locking component 5 are reliable and controllable, and do not require manual intervention, thereby having high safety performance.

[0067] In other embodiments of the present application, the second driving device 6 may be other types of driving components, such as a combination of a motor and a transmission device, which can drive the locking component 5 to switch between the locking position and the unlocking position.

[0068] In some embodiments of the present application, Figure 1 As shown, the lifting module 13 includes a guide rail 3 and a lifting slider 1. The guide rail 3 includes a slideway, which is arranged along the movement direction of the lifting slider 1 and is used to regulate the movement direction of the lifting slider 1. The lifting slider 1 is movably mounted on the guide rail 3 and is raised and lowered along the length of the guide rail 3. The guide rail 3 extends in the F1-F2 direction and is arranged to extend along the F1-F2 direction. The guide rail 3 guides the movement of the lifting slider 1, ensuring that the lifting slider 1 moves in a straight line and preventing the lifting slider 1 from flipping.

[0069] In some embodiments, the guide rail 3 has a guide track, and the lifting slider 1 has a guide groove. Both the guide track and the guide groove extend along the F1-F2 direction, and the guide track and the guide groove are embedded and matched.

[0070] In some embodiments, the guide rail 3 has a guide cylinder, and the lifting slider 1 at least partially extends into the guide cylinder, and the lifting slider 1 can be lifted and lowered along the guide cylinder.

[0071] In some embodiments of the present application, reference is made to Figure 1 As shown, the lifting slider 1 has a slider locking surface 11, and the locking member 5 locks the lifting slider 1 by supporting the slider locking surface 11 from bottom to top. The slider locking surface 11 can be the bottom surface of the lifting slider 1. In this way, when the lifting slider 1 moves downward from the first position, it can well contact the locking member 5, so that the locking member 5 supports the slider locking surface 11.

[0072] Optionally, the locking surface 11 of the slider is a plane, and the locking surface of the locking member 5 is also a plane. In this way, when the locking member 5 supports the locking surface 11 of the slider, the surface fits together, and the support is relatively stable.

[0073] In some embodiments of the present application, the lifting system 10 further includes a locking position sensor 9 for detecting whether the locking member 5 has reached the locking position. The first drive device 4 and the locking position sensor 9 can be connected to a control system of the vehicle 1000 .

[0074] In some embodiments, when the locking position sensor 9 detects that the locking member 5 reaches the locking position, it is considered that the lifting and locking is completed, and the vehicle body pushes the lifting slider 1 downward under the action of gravity until the lifting slider 1 is in contact with the locking member 5.

[0075] In other embodiments, when the locking position sensor 9 detects that the locking member 5 reaches the locking position, the locking position sensor 9 sends a locking signal to the control system, and the control system sends an instruction to the first drive device 4. The first drive device 4 drives the lifting slider 1 to move downward from the first position until the lifting slider 1 contacts the locking member 5. At this time, it is considered that the lifting and locking are completed.

[0076] In some embodiments of the present application, the first driving device 4 includes a driving member 41 and a transmission mechanism 42 . The driving member 41 is used to output power, and the transmission mechanism 42 is used to convert the rotational motion of the driving member 41 into linear motion of the lifting module 13 .

[0077] In some embodiments of the present application, the lift slider 1 is fixedly connected to the lift rod 2. The driving member 41 drives the lift rod 2 up and down through the transmission mechanism 42. When the lift rod 2 rises and falls, the lift slider 1 is synchronously raised and lowered. By providing the lift rod 2, the first driving device 4 can be arranged at a position farther away from the lift slider 1, thereby effectively utilizing the space under the vehicle body.

[0078] Optionally, the driving member 41 is a motor.

[0079] In some embodiments of the present application, the transmission mechanism 42 includes a worm 421, a worm wheel 422 and a lifting swing arm 423. The worm 421 is connected to the driving member 41, the worm wheel 422 is engaged with the worm 421, one end of the lifting swing arm 423 is fixedly connected to the worm wheel 422, and the other end of the lifting swing arm 423 is hingedly connected to the lifting push rod 2. Figure 1As shown, when the output shaft of the motor rotates forward, the motor drives the worm 421 to rotate forward, the worm 421 drives the worm wheel 422 to rotate clockwise, the worm wheel 422 drives the lifting swing arm 423 to rotate clockwise, and the lifting swing arm 423 drives the lifting push rod 2 to rise, thereby achieving the rise of the lifting slider 1. When the output shaft of the motor rotates reversely, the motor drives the worm 421 to rotate reversely, the worm 421 drives the worm wheel 422 to rotate counterclockwise, the worm wheel 422 drives the lifting swing arm 423 to rotate counterclockwise, and the lifting swing arm 423 drives the lifting push rod 2 to descend, thereby achieving the descent of the lifting slider 1.

[0080] In some embodiments of the present application, the transmission mechanism 42 includes a gear, and the lift rod 2 is provided with a rack. The driving member 41 drives the gear to rotate, and the rack and gear mesh to drive the lift rod 2 to rise and fall, thereby driving the lift slider 1 to rise and fall synchronously. Specifically, when the motor drives the gear to rotate in the forward direction, the rack moves upward, and the lift rod 2 moves upward synchronously, thereby achieving the rise of the lift slider 1. When the motor drives the gear to rotate in the reverse direction, the rack moves downward, and the lift rod 2 moves downward synchronously, thereby achieving the descent of the lift slider 1.

[0081] In some embodiments of the present application, the transmission mechanism 42 may also be other types of structures, which are not listed here one by one.

[0082] In some embodiments of the present application, reference is made to Figure 1 As shown, the lifting system 10 further includes a first position sensor 7 , which is used to detect whether the lifting module 13 reaches the first position.

[0083] In some embodiments of the present application, reference is made to Figure 1 As shown, the lifting system 10 further includes a second position sensor 8 , which is used to detect whether the lifting module 13 reaches the second position.

[0084] In some embodiments of the present application, the lifting system 10 further includes a first position sensor 7 and a second position sensor 8. The first position sensor 7 is located above the second position sensor 8. The first position sensor 7 is used to detect whether the lifting module 13 has reached the first position, and the second position sensor 8 is used to detect whether the lifting module 13 has reached the second position. Specifically, the first drive device 4, the first position sensor 7, and the second position sensor 8 are all connected to the control system of the vehicle 1000. When the vehicle body needs to be lifted, the control system of the vehicle 1000 sends a lift and lock signal to the lifting system 10. After the lifting system 10 receives the lift and lock signal, the first drive device 4 drives the lifting module 13 to rise. After the first position sensor 7 detects that the lifting module 13 has reached the first position, it transmits a first in-position signal to the control system. The control system sends a locking instruction to the second drive device 6. The second drive device 6 drives the locking member 5 to move to the locking position, and the lifting module 13 moves downward to the position where the locking member 5 supports the lifting module 13.

[0085] When it is no longer necessary to lift the vehicle body, the control system of the vehicle 1000 sends a release signal to the lifting system 10. After the lifting system 10 receives the release signal, the first drive device 4 drives the lifting module 13 to rise. After the first position sensor 7 detects that the lifting module 13 has reached the first position again, the first in-position signal is transmitted to the control system. The control system sends an unlocking instruction to the second drive device 6. The second drive device 6 drives the locking member 5 to move to the unlocking position. The first drive device 4 drives the lifting module 13 to descend. After the second position sensor 8 detects that the lifting module 13 has reached the second position, the second in-position signal is transmitted to the control system. The control system sends a stop instruction to the first drive device 4 to stop the lifting module 13 from moving downward.

[0086] Figure 2 This is a schematic diagram of the lifting and locking process of an embodiment, referring to Figure 2 The lifting and locking steps are as follows: 1. Determine whether the lifting system 10 has received a lifting and locking signal. If the lifting system 10 has not received the lifting and locking signal, continue to determine whether the lifting system 10 has received a lifting and locking signal. If the lifting system 10 has received the lifting and locking signal, the first drive device 4 drives the lifting module 13 to rise. 2. After the first drive device 4 drives the lifting module 13 to rise, determine whether the lifting module 13 has reached the first position. If the lifting module 13 has not reached the first position, the first drive device 4 continues to drive the lifting module 13 to rise. When the lifting module 13 reaches the first position, energize the electromagnetic element 61 to move the locking element 5 to the locking position. 3. After energizing the electromagnetic element 61, determine whether the locking position sensor 9 is equal to 1. If the locking position sensor 9 is not equal to 1, continue to energize the electromagnetic element 61. When the locking position sensor 9 is equal to 1, it is considered that the lifting and locking is complete.

[0087] Figure 3 is a schematic diagram of the lifting and releasing process of an embodiment, referring to Figure 3 The steps of lifting release are as follows: 1. Determine whether the lifting system 10 has received a release signal. If the lifting system 10 has not received a release signal, continue to determine whether the lifting system 10 has received a release signal. If the lifting system 10 has received a release signal, the first drive device 4 drives the lifting module 13 to rise. 2. After the first drive device 4 drives the lifting module 13 to rise, determine whether the lifting module 13 has reached the transition position. If the lifting module 13 has not reached the transition position, the first drive device 4 continues to drive the lifting module 13 to rise. When the lifting module 13 reaches the transition position, the electromagnetic component 61 is de-energized, and the elastic element 62 moves the locking component 5 to the unlocked position. 3. After the electromagnetic component 61 is de-energized, determine whether the locking position sensor 9 is equal to 0. If the locking position sensor 9 is not equal to 0, continue to keep the electromagnetic component 61 de-energized. If the locking position sensor 9 is equal to 0, the first drive device 4 drives the lifting module 13 to descend. 4. After the first driving device 4 drives the lifting module 13 to descend, it is determined whether the lifting module 13 reaches the second position. When the lifting module 13 has not reached the second position, the first driving device 4 continues to drive the lifting module 13 to descend; when the lifting module 13 reaches the second position, it is considered that the release is completed.

[0088] Reference Figure 4 As shown, the suspension system 100 of the vehicle 1000 according to the embodiment of the second aspect of the present application includes the above-mentioned lifting system 10 for the vehicle 1000.

[0089] According to the suspension system 100 of the vehicle 1000 in the embodiment of the present application, its lifting system 10 can lift the body of the vehicle 1000, so that when other vehicles approach the vehicle from the side, the lifting system 10 can lift the corresponding side of the body, thereby reducing personal injury to the occupants of the vehicle when other vehicles collide with the vehicle from the side. By using the locking module 56 to lock the lifting module 13 in the target position, it can effectively prevent the change in body height from causing secondary injury to the occupants in the vehicle.

[0090] In some embodiments of the present application, the driver's seat and the passenger seat of the vehicle 1000 are arranged in a horizontal direction, there is only one lifting system 10, and the lifting system 10 is distributed on the lateral left side or the lateral right side of the vehicle.

[0091] In some embodiments of the present application, the driver's seat and the passenger seat of the vehicle 1000 are arranged in a transverse direction, and there are multiple lifting systems 10, with at least one lifting system 10 being provided on both the left and right sides of the vehicle 1000. The lifting system 10 on the left side of the vehicle 1000 is used to lift the left side of the vehicle body, and the lifting system 10 on the right side of the vehicle 1000 is used to lift the right side of the vehicle body. The suspension system 100 is an active suspension, which provides great convenience and possibilities for the intelligent level of the vehicle. The lifting module 13 of each lifting system 10 can be raised or lowered independently, and the vehicle body on the corresponding side will be raised or lowered.

[0092] Optionally, a lifting system 10 is provided at each of the left front wheel, left rear wheel, right front wheel, and right rear wheel of the vehicle 1000. The lifting systems 10 at the left front wheel and left rear wheel lift the left lateral side of the vehicle body, and the lifting systems 10 at the right front wheel and right rear wheel lift the right lateral side of the vehicle body.

[0093] A lifting system 10 is designed in the suspension system 100, which can work together with the active suspension to quickly raise the vehicle body height when a side collision risk is detected to ensure the safety of the driver and passengers.

[0094] Reference Figure 5 As shown, a vehicle 1000 according to an embodiment of the third aspect of the present application includes the above-mentioned suspension system 100.

[0095] According to the vehicle 1000 of the embodiment of the present application, its lifting system 10 is capable of lifting the body of the vehicle 1000, so that when other vehicles approach the vehicle from the side, the lifting system 10 can lift the corresponding side of the body, thereby reducing personal injury to the occupants of the vehicle when other vehicles collide with the vehicle from the side. By using the locking module 56 to lock the lifting module 13 in the target position, it is possible to effectively prevent the change in body height from causing secondary injury to the occupants in the vehicle.

[0096] According to the control method of the vehicle 1000 of the fourth aspect embodiment of the present application, which is applied to the lifting system 10 of the above embodiment, the control method includes: when it is determined that the vehicle 1000 is at risk of side collision, the first drive device 4 drives the lifting module 13 to drive the vehicle body to move upward, and locks the lifting module 13 at the target position through the locking module 56.

[0097] According to the control method of the vehicle 1000 in the embodiment of the present application, when the vehicle 1000 has a risk of side collision, its lifting system 10 can lift the body of the vehicle 1000, so that when other vehicles approach the vehicle from the side, the lifting system 10 can lift the corresponding side of the body, thereby reducing the personal injury to the occupants of the vehicle when other vehicles collide with the vehicle from the side. By using the locking module 56 to lock the lifting module 13 in the target position, it can effectively prevent the change in the body height from causing secondary injury to the occupants in the vehicle.

[0098] In some embodiments of the present application, the control method includes:

[0099] S1: Determine whether the vehicle 1000 has a side collision risk;

[0100] S2: When the vehicle 1000 has a side collision risk, determining whether the side collision risk direction is the lateral left side or the lateral right side of the vehicle 1000;

[0101] S3: Sending a lifting and locking signal to the lifting system 10 on the corresponding side according to the determined side collision risk direction.

[0102] That is, when the vehicle 1000 has a side collision risk, it is determined whether it is a left side collision risk or a right side collision risk, and the lifting system 10 on the corresponding side is lifted and locked according to the determined side collision risk direction.

[0103] In some embodiments of the present application, the control method further includes:

[0104] After a preset time, determining whether the vehicle 1000 has collided on the side with a side collision risk;

[0105] If the vehicle 1000 collides on the side with a side collision risk, no release signal is generated;

[0106] If the vehicle 1000 does not collide in the side collision risk direction, a release signal is generated.

[0107] In some embodiments of the present application, if the vehicle 1000 collides on the side with side collision risk, a release signal is generated upon receiving a user signal.

[0108] Alternatively, the user signal may be a manual switch command. Thus, after a preset time t1, a determination is made as to whether the vehicle 1000 has collided on the side with the side collision risk. If the vehicle 1000 has collided in the side collision risk direction, no release signal is generated, and no release signal is sent to the lift system 10 on the corresponding side. The system waits for a manual switch command, and upon receiving the manual switch command, a release signal is generated. If the vehicle 1000 has not collided in the side collision risk direction, a release signal is generated and sent to the lift system 10 on the corresponding side, controlling the vehicle body to return to normal.

[0109] That is to say, after the lifting system 10 on the corresponding side performs the lifting and locking operation, it is determined whether the lifting and locking of the corresponding side is completed. When the lifting and locking is not completed, the lifting system 10 on the corresponding side continues to perform the lifting and locking operation; when the lifting and locking is completed, the vehicle body is maintained at a certain height to prevent the change in vehicle body height from causing secondary injuries to the occupants in the vehicle. After a delay of the preset time t1, it is determined whether the vehicle 1000 collides in the direction of the side collision risk.

[0110] In some embodiments of the present application, if the vehicle 1000 collides in the direction of a side collision risk, the manual switch is first triggered, and then a release signal is sent to the lift system 10 on the corresponding side. In other words, if the vehicle 1000 collides in the direction of a side collision risk, it is determined whether the manual switch is pressed. If the manual switch is pressed, the lift system 10 on that side is released. It is further determined whether the release of that side is complete. If it is complete, the release operation is terminated and the vehicle body returns to normal. If it is not complete, the lift system 10 on that side continues to be released.

[0111] In some embodiments of the present application, a collision risk is considered to exist when a sideways target vehicle is relatively close to the host vehicle and has a significant velocity component toward the host vehicle. Specifically, determining whether vehicle 1000 is at risk of a sideways collision includes determining whether the lateral distance between the sideways target vehicle and the host vehicle is within a preset distance value and whether the relative velocity between the sideways target vehicle and the host vehicle in the lateral direction reaches a preset velocity value. If the lateral distance between the sideways target vehicle and the host vehicle is within the preset distance value and the relative velocity between the sideways target vehicle and the host vehicle in the lateral direction reaches a preset velocity value, then vehicle 1000 is at risk of a sideways collision; otherwise, vehicle 1000 is not at risk of a sideways collision. By determining the lateral distance between the sideways target vehicle and the host vehicle and the relative velocity between the sideways target vehicle and the host vehicle in the lateral direction, it is possible to predict whether the sideways target vehicle will collide with the host vehicle. When a sideways collision is imminent, the vehicle body on the side of the vehicle that is about to collide is quickly raised and maintained at a certain height to protect the safety of the driver and passengers. Maintaining a certain height for a long time can prevent secondary injuries to passengers caused by height changes.

[0112] Optionally, a camera and / or a laser radar is used to detect the relative speed between the side target vehicle and the vehicle.

[0113] like Figure 6 As shown, when the vehicle detects a side collision risk, it first determines whether the side collision risk is on the left or right side, and controls the active suspension and lifting system 10 to take corresponding actions based on the determined side collision risk to avoid or reduce the damage to the people in the vehicle caused by the side collision.

[0114] (1) When the side collision risk is determined to be on the left side, the lifting module 13 of the left lifting system 10 is controlled to lift and lock. After the left side is lifted and locked, a predetermined time t1 is delayed to determine whether a collision has occurred. If a collision has occurred, in order to avoid secondary injury to the occupants due to the change in vehicle body height, the lift release command can only be executed after the lift release manual switch is pressed. If no collision has occurred, the lifting module 13 of the left lifting system 10 is controlled to slowly release, and the vehicle body returns to normal.

[0115] (2) When the side collision risk is determined to be on the right side, the lifting module 13 of the right lifting system 10 is controlled to lift and lock. After it is determined that the right side is lifted and locked, a predetermined time t1 is delayed to determine whether a collision has occurred. If a collision is determined to have occurred, in order to avoid secondary injury to the occupants due to the change in vehicle body height, the lift release command can only be executed after the lift release manual switch is pressed. If it is determined that no collision has occurred, the lifting module 13 of the right lifting system 10 is controlled to slowly release, and the vehicle body returns to normal.
