Examples of the embodiments are shown in the drawings, in which the same or similar components are denoted by the same or similar reference numerals, and therefore repeated description is omitted. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

[0041] In the description of the present application, the terms "first", "second", etc. are used only for the purpose of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise explicitly and specifically limited.

[0042] A lifting system 10 for a vehicle 1000, a suspension system 100 of the vehicle 1000, the vehicle 1000, and a control method of the vehicle 1000 according to embodiments of the present application are described in detail below with reference to Figs. 1-6.

[0043] Referring to Fig. 1, the lifting system 10 for the vehicle 1000 according to an embodiment of the present application includes a lifting module 13, a first driving device 4, and a locking module 56.

[0044] The lifting module 13 is adapted to connect the vehicle body, and the first driving device 4 is used to drive the lifting of the lifting module. The lifting module 13, the first driving device 4 and the locking module 56 are configured to: when it is determined that the vehicle has a side collision risk, the first driving device 4 drives the lifting module 13 to move the vehicle body upward, and the lifting module 13 is locked at the target position by the locking module 56, so as to lock the vehicle body at the target position.

[0045] When other vehicles approach the vehicle, the lifting system 10 of the vehicle can lift the corresponding side of the vehicle body. Specifically, the first driving device 4 drives the lifting module 13 to rise, and the lifting module 13 drives the side of the vehicle body to rise. In this way, when other vehicles collide with the vehicle, the personal injury of the passengers in the vehicle 1000 can be reduced. When the lifting module 13 rises to a certain height, the locking module 56 can lock the lifting module 13, so as to lock the vehicle body at the target position, thereby effectively preventing the change of the height of the vehicle body from causing secondary injury to the passengers in the vehicle.

[0046] According to the lifting system 10 for the vehicle 1000 provided in the embodiments of the present application, the vehicle body of the vehicle 1000 can be lifted. When other vehicles approach the vehicle from the side, the lifting system 10 can lift the corresponding side of the vehicle body, so as to reduce the personal injury of the passengers in the vehicle when other vehicles collide with the vehicle from the side. By using the locking module 56 to lock the lifting module 13 at the target position, the change of the height of the vehicle body can be effectively prevented from causing secondary injury to the passengers in the vehicle.

[0047] In some embodiments of the present application, the target position is determined according to vehicle information of the vehicle approaching from the side. Specifically, different vehicle information corresponds to different target positions. In this way, for different vehicles approaching from the side, the vehicle body of the vehicle can be lifted to the target position corresponding to the vehicle approaching from the side, so as to better protect the passengers in the vehicle.

[0048] 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 vehicle model information and front bumper position information.

[0049] In some embodiments, a camera installed on the vehicle is used to collect images of the vehicle approaching from the side, and the vehicle model of the vehicle approaching from the side can be determined by analyzing the images.

[0050] In some embodiments, a camera installed on the vehicle is used to collect images of the vehicle approaching from the side, and the front bumper position information of the vehicle approaching from the side can be determined by analyzing the images.

[0051] 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.

[0052] In some embodiments, the different target positions are different positions in the height direction of the vehicle 1000.

[0053] Specifically, the larger the vehicle model, the higher the target position at which the vehicle body needs to be lifted. For example, the vehicle model can be a sedan, an SUV, an off-road vehicle, etc., and the target position at which the vehicle body needs to be lifted is determined according to the vehicle model. For example, when the side-approaching vehicle is an off-road vehicle, the target position at which the vehicle body needs to be lifted by the vehicle lifting module 13 is higher than when the side-approaching vehicle is an SUV, and the target position at which the vehicle body needs to be lifted when the side-approaching vehicle is an SUV is higher than when the side-approaching vehicle is a sedan. In this way, for different vehicle models of the side-approaching vehicle, the vehicle body can be lifted to the corresponding target position of the side-approaching vehicle, so as to better protect the passengers in the vehicle.

[0054] Similarly, the higher the front bumper position of the side-approaching vehicle, the higher the target position at which the vehicle body needs to be lifted. In this way, for different front bumper positions of the side-approaching vehicle, the vehicle body can be lifted to the corresponding target position of the side-approaching vehicle, so as to better protect the passengers in the vehicle.

[0055] In some embodiments of the present application, referring to FIG. 1, the locking module 56 includes a locking member 5 and a second driving device 6 for driving the locking member 5 to act. The locking member 5 has a locking position and an unlocking position. When the locking member 5 is in the locking position, the locking member 5 is used to lock the lifting module 13; when the locking member 5 is in the unlocking position, the locking member 5 is used to unlock the lifting module 13, and the second driving device 6 is used to drive the locking member 5 to switch between the locking position and the unlocking position.

[0056] The second driving device 6 is configured to drive the locking member 5 to the locking position when it is determined that the vehicle 1000 has a side collision risk, so that the lifting module 13 is locked at the target position. In this way, the vehicle body can be locked at the target position, avoiding the side of the vehicle body with a side collision risk from descending, effectively preventing the change in vehicle body height from causing secondary injury to the passengers in the vehicle.

[0057] In some embodiments of the present application, the lifting module 13, the first driving device 4, the second driving device 6 and the locking member 5 are configured to: when it is determined that the vehicle 1000 is at risk of side collision, after the first driving device 4 drives the lifting module 13 to the first position, the second driving device 6 drives the locking member 5 to the locking position, so that the lifting module 13 is locked at the target position. Specifically, after the lifting system 10 receives the lifting and locking signal, the first driving device 4 drives the lifting module 13 to rise, and after the lifting module 13 reaches the first position, the second driving 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, at which time the lifting module 13 is locked at the target position.

[0058] That is, 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, the lifting module 13 rises, and when the lifting module 13 rises to the first position, the locking member 5 moves to the locking position first, at which time there is a gap between the lifting module 13 and the locking member 5, and then the lifting module 13 is moved downward until the gap between the lifting module 13 and the locking member 5 is reduced to zero, the lifting module 13 is supported by the locking member 5, and the lifting module 13 cannot continue to move downward, and the side vehicle body remains in the lifted state.

[0059] In some embodiments, during the movement of the locking member 5 to the locking position to fit the lifting module 13, the downward movement of the lifting module 13 can be achieved by the downward pushing of the vehicle body on the lifting module 13 under the action of gravity, and no longer rely on the active driving of the first driving device 4.

[0060] In some other embodiments, during the movement of the locking member 5 to the locking position to fit the lifting module 13, the downward movement of the lifting module 13 can rely on the active driving of the first driving device 4.

[0061] In some embodiments of the present application, the lifting module 13, the first driving device 4, the second driving device 6 and the locking member 5 are configured to: when the locking member 5 locks the lifting module at the target position, and it is determined that the vehicle 1000 is not at risk of side collision, after the first driving device 4 drives the lifting module 13 to the transition position, the second driving device 6 drives the locking member 5 to the unlocking position, and the first driving device 4 drives the lifting module 13 to the second position. When the side collision risk is removed, the locking member 5 is unlocked, so that the lifting module 13 connected to the side vehicle body can be lowered to the second position, thereby driving the side vehicle body to be lowered.

[0062] Specifically, after the release signal is received by the lifting system 10, the first driving device 4 drives the lifting module 13 to rise to a transition position, the second driving device 6 drives the locking member 5 to move to an unlocking position, the first driving device 4 drives the lifting module 13 to descend until the lifting module 13 reaches a second position.

[0063] That is, when the vehicle body no longer needs to be lifted, the control system of the vehicle 1000 sends a release signal to the lifting system 10, after the release signal is received by the lifting system 10, the lifting module 13 rises to a transition position, and at this time, the locking member 5 is still in the locking position, so that the lifting module 13 is separated from the locking member 5, then the locking member 5 moves to the unlocking position, and then the first driving device 4 drives the lifting module 13 to descend, and the locking member 5 is withdrawn to the unlocking position, so it will not block the downward movement of the lifting module 13, until the lifting module 13 reaches the second position. When the lifting module 13 is in the second position, the side vehicle body is at the normal height and is not lifted.

[0064] In some embodiments of the present application, the transition position is between the first position and the second position, or the first position is between the transition position and the second position, so that the transition position and the first position are different positions, and a position sensor is arranged at each of the transition position, the first position and the second position to detect different positions of the lifting module 13.

[0065] Alternatively, in some other embodiments of the present application, the transition position and the first position are the same position. In this way, a position sensor arranged at the transition position and the first position can detect the transition position and the first position at the same time, which can save the number of sensors. In some embodiments of the present application, the second driving device 6 is configured to: when it is determined that the vehicle 1000 has a side collision risk, the second driving device 6 is used to drive the locking member 5 to move to the locking position in a first direction, so that the lifting module 13 is locked in the target position; when the locking member 5 locks the lifting module 13 in the target position, and it is determined that the vehicle 1000 does not have a side collision risk, the second driving device 6 is used to drive the locking member 5 to move to the unlocking position in a second direction, wherein the first direction is opposite to the second direction. For example, in the embodiment shown in FIG. 1, the first direction is the F3 direction shown in FIG. 1, and the second direction is the F4 direction shown in FIG. 1, and the lifting module 13 rises and falls in the F1-F2 direction, wherein the F1-F2 direction is different from the F3-F4 direction, so that the movement of the lifting module 13 and the movement of the locking member 5 do not easily interfere with each other. For example, the F1-F2 direction and the F3-F4 direction can be perpendicular or at an acute angle.

[0066] In some embodiments of the present application, referring to FIG. 1, the second driving device 6 comprises an electromagnetic member 61. When it is determined that the vehicle 1000 has a side collision risk, a first current flows to the electromagnetic member 61, and an acting force generated by the electromagnetic member 61 drives the locking member 5 to move in a first direction to a 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 has no side collision risk, a second current flows to the electromagnetic member 61, and an acting force generated by the electromagnetic member 61 drives the locking member 5 to move in a second direction to an unlocking position, wherein the first current and the second current are opposite in direction.

[0067] In some embodiments of the present application, referring to FIG. 1, the second driving device 6 comprises an electromagnetic member 61 and an elastic member 62. When it is determined that the vehicle 1000 has a side collision risk, the electromagnetic member 61 is powered to generate an acting force, which drives the locking member 5 to move in a first direction to a 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 has no side collision risk, the electromagnetic member 61 is powered off, and an acting force generated by the elastic member 62 drives the locking member 5 to move in a second direction to an unlocking position, wherein the first direction and the second direction are opposite. That is, the elastic member 62 is used to apply a restoring force to the locking member 5 to move to the unlocking position. By setting the electromagnetic member 61 and the elastic member 62 to control the position of the locking member 5, the locking and unlocking actions of the locking member 5 are reliable and controllable, and do not require manual intervention, and the safety performance is higher.

[0068] In some embodiments of the present application, referring to FIG. 1, the second driving device 6 comprises an electromagnetic member 61 and an elastic member 62. When it is determined that the vehicle 1000 has a side collision risk, the electromagnetic member 61 is powered to generate an acting force, which drives the locking member 5 to move in a first direction to a 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 has no side collision risk, the electromagnetic member 61 is powered off, and an acting force generated by the elastic member 62 drives the locking member 5 to move in a second direction to an unlocking position, wherein the first direction and the second direction are opposite. That is, the elastic member 62 is used to apply a restoring force to the locking member 5 to move to the unlocking position. By setting the electromagnetic member 61 and the elastic member 62 to control the position of the locking member 5, the locking and unlocking actions of the locking member 5 are reliable and controllable, and do not require manual intervention, and the safety performance is higher.

The guide rail 3 comprises a sliding channel arranged along the movement direction of the lifting slider 1, and the sliding channel is used to regularize the movement direction of the lifting slider 1. The lifting slider 1 is movably arranged in the guide rail 3, and the lifting slider 1 is lifted along the length extension direction of the guide rail 3. The length extension direction of the guide rail 3 is the F1-F2 direction, and the guide rail 3 is arranged along the F1-F2 direction. The guide rail 3 can guide the movement of the lifting slider 1, ensure the linear movement of the lifting slider 1, and prevent the lifting slider 1 from overturning.

[0070] In some embodiments, the guide rail 3 has a guide rail, and the lifting slider 1 has a guide groove. The guide rail and the guide groove are arranged along the F1-F2 direction, and the guide rail is embedded and matched with the guide groove.

[0071] 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 along the guide cylinder.

[0072] In some embodiments of the present application, referring to FIG. 1, the lifting slider 1 has a slider locking surface 11, and the locking member 5 supports the slider locking surface 11 from below to lock the lifting slider 1. The slider locking surface 11 can be the bottom surface of the lifting slider 1, so that the lifting slider 1 can be in good contact with the locking member 5 when moving downward from the first position, and the locking member 5 supports the slider locking surface 11.

[0073] For example, the slider locking surface 11 is a flat surface, and the locking surface of the locking member 5 is also a flat surface, so that the locking member 5 supports the slider locking surface 11 in a surface-to-surface manner, and the support is relatively stable.

[0074] In some embodiments of the present application, the lifting system 10 further comprises a locking position sensor 9 for detecting whether the locking member 5 reaches the locking position. The first driving device 4 and the locking position sensor 9 can be connected to the control system of the vehicle 1000.

[0075] 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 are 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.

[0076] In some 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-in-position signal to the control system, and the control system sends an instruction to the first driving device 4, and the first driving device 4 drives the lifting slider 1 to move downward from the first position until the lifting slider 1 is in contact with the locking member 5, at which time it is considered that the lifting and locking are completed.

[0077] In some embodiments of the present application, the first driving device 4 comprises 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 rotary motion of the driving member 41 into the linear motion of the lifting module 13.

[0078] In some embodiments of the present application, the lifting slider 1 is fixedly connected with the lifting jacks 2, the driving member 41 drives the lifting jacks 2 to rise and fall through the transmission mechanism 42, and the lifting jacks 2 drive the lifting slider 1 to rise and fall synchronously when rising and falling. By setting the lifting jacks 2, the first driving device 4 can be arranged at a position far away from the lifting slider 1, so as to reasonably utilize the space below the vehicle body.

[0079] For example, the driving member 41 is an electric motor.

[0095] Referring to FIG. 5, the vehicle 1000 according to the third aspect of the present application comprises the above-mentioned suspension system 100.

[0096] The vehicle 1000 according to the embodiments of the present application can lift the vehicle body of the vehicle 1000 by the lifting system 10, so that when other vehicles approach the vehicle from the side, the lifting system 10 can lift the corresponding side of the vehicle body, thereby reducing the personal injury to the passengers of the vehicle caused by the side collision of other vehicles, and the target position of the lifting module 13 can be effectively prevented from changing the height of the vehicle body to cause secondary injury to the passengers in the vehicle by locking the lifting module 13 at the target position by the locking module 56.

[0097] The control method of the vehicle 1000 according to the fourth aspect of the present application is applied to the above-mentioned lifting system 10, and the control method comprises: when it is determined that the vehicle 1000 has a side collision risk, the first driving device 4 drives the lifting module 13 to drive the vehicle body to move upward, and the lifting module 13 is locked at the target position by the locking module 56.

By locking the lifting module 13 at the target position by using the locking module 56, the change in the height of the vehicle body can be effectively prevented from causing secondary injury to the passengers in the vehicle.

[0099] In some embodiments of the present application, the control method comprises:

[0100] S1: determining whether the vehicle 1000 has a side collision risk;

[0101] S2: when the vehicle 1000 has a side collision risk, determining whether the side collision risk is on the lateral left side or the lateral right side of the vehicle 1000;

[0102] S3: sending a lifting and locking signal to the lifting system 10 on the corresponding side according to the determined side collision risk direction.

[0103] That is, when the vehicle 1000 has a side collision risk, it is determined whether the side collision risk is on the left side or the right side. According to the determined side collision risk direction, the lifting and locking operation is performed on the lifting system 10 on the corresponding side.

[0104] In some embodiments of the present application, the control method further comprises:

[0105] After a preset time, determining whether a collision occurs on the side collision risk side of the vehicle 1000;

[0106] If a collision occurs on the side collision risk side of the vehicle 1000, no release signal is generated;

[0107] If no collision occurs on the side collision risk side of the vehicle 1000, a release signal is generated.

[0108] In some embodiments of the present application, if a collision occurs on the side collision risk side of the vehicle 1000, the release signal is generated again when a user signal is received.

[0109] In some embodiments, the user signal can be a manual switch instruction. In this way, after the preset time t1, it is determined whether a collision occurs on the side collision risk side of the vehicle 1000; if a collision occurs on the side collision risk side of the vehicle 1000, no release signal is generated, no release signal is sent to the lifting system 10 on the corresponding side, and a manual switch instruction is waited for. When the manual switch instruction is received, the release signal is generated again; if no collision occurs on the side collision risk side of the vehicle 1000, a release signal is generated, a release signal is sent to the lifting system 10 on the corresponding side, and the vehicle body is controlled to return to a normal state.

[0110] That is, after the lifting and locking operation of the corresponding side lifting system 10 is performed, it is determined whether the corresponding side lifting system 10 is locked, and if not, the lifting and locking operation of the corresponding side lifting system 10 is continued; if the corresponding side lifting system 10 is locked, the vehicle body is kept at a certain height to prevent the change of the height of the vehicle body from causing secondary injury to the passengers in the vehicle, and after a preset time t1 is delayed, it is determined whether the vehicle 1000 collides in the side collision risk direction.

[0111] In some embodiments of the present application, if the vehicle 1000 collides in the side collision risk direction, the manual switch is triggered first, and then a release signal is sent to the corresponding side lifting system 10. That is, if the vehicle 1000 collides in the side collision risk direction, it is determined whether the manual switch is pressed, and if the manual switch is pressed, the corresponding side lifting system 10 is released, and it is further determined whether the release of the corresponding side lifting system 10 is completed, and if so, the release operation is ended and the vehicle body returns to the normal state; if not, the corresponding side lifting system 10 is continuously released.

[0112] In some embodiments of the present application, when the side target vehicle is close to the vehicle and has a large speed component towards the vehicle, it is considered to have a collision risk. Specifically, determining whether the vehicle 1000 has a side collision risk includes: determining whether the lateral distance between the side target vehicle and the vehicle is within a preset distance value and whether the relative speed between the side target vehicle and the vehicle in the lateral direction of the vehicle reaches a preset speed value; if the lateral distance between the side target vehicle and the vehicle is within the preset distance value and the relative speed between the side target vehicle and the vehicle in the lateral direction of the vehicle reaches the preset speed value, the vehicle 1000 has a side collision risk; otherwise, the vehicle 1000 has no side collision risk. By determining the lateral distance between the side target vehicle and the vehicle and the relative speed between the side target vehicle and the vehicle in the lateral direction of the vehicle, it can be predicted whether the side target vehicle will collide with the vehicle, and when the side collision is about to occur, the vehicle body on the side about to collide is quickly lifted and kept at a certain height to protect the safety of the driver and the passengers, and long-time keeping at a certain height can avoid secondary injury to the passengers caused by the change of the height.

[0113] In some embodiments, a camera and / or a laser radar are used to detect the relative speed between the side target vehicle and the vehicle.

[0114] As shown in FIG. 6, when the vehicle detects a side collision risk, it is first determined whether the side collision risk is on the left side or the right side, and the active suspension and the lifting system 10 are controlled to make corresponding actions according to the determined side collision risk to avoid or reduce the injury to the passengers on the vehicle caused by the side collision.

[0115] (1) When the side collision risk is judged as left side, the lifting module 13 of the left lifting system 10 is controlled to lift and lock. When it is judged that the left lifting and locking is completed, a preset time t1 is delayed, and it is judged whether a collision occurs. If it is judged that a collision occurs, in order to avoid the change of the height of the vehicle body to the secondary injury of the people on the vehicle, the lifting release instruction can be executed after the lifting release manual switch is pressed. If it is judged that a collision does not occur, the lifting module 13 of the left lifting system 10 is controlled to slowly release, and the vehicle body returns to the normal state.

[0116] (2) When the side collision risk is judged as right side, the lifting module 13 of the right lifting system 10 is controlled to lift and lock. When it is judged that the right lifting and locking is completed, a preset time t1 is delayed, and it is judged whether a collision occurs. If it is judged that a collision occurs, in order to avoid the change of the height of the vehicle body to the secondary injury of the people on the vehicle, the lifting release instruction can be executed after the lifting release manual switch is pressed. If it is judged that a collision does not occur, the lifting module 13 of the right lifting system 10 is controlled to slowly release, and the vehicle body returns to the normal state.
