[0031] Embodiments of the present application are described in detail below with reference to the attached drawings, which are meant to be exemplary and not limiting.

[0032] A vehicle collision seat active control method and a controller are described below with reference to the accompanying drawings. The related art mentioned in the background focuses on passive safety protection in the case of a frontal collision, lacks adaptability to various safety conditions in vehicle driving, and thus has a low overall safety protection level. To solve the above technical problems, the vehicle collision seat active control method provided by the present application can combine active safety and passive safety technology, detect the current side collision risk through external sensors, perform a pre-lifting action on the seat when a collision risk is determined, and raise the height of the collision side of the seat when a collision occurs, thereby reducing the contact between the driver and the collision object and improving the overall safety protection level of the vehicle. Thus, the related art focuses on passive safety protection in the case of a frontal collision, lacks adaptability to various safety conditions in vehicle driving, and thus has a low overall safety protection level.

[0033] Specifically, Figure 1 A flowchart of a vehicle collision seat active control method provided by an embodiment of the present application is shown in the figure.

[0034] As Figure 1 shown, the vehicle collision seat active control method includes the following steps:

[0035] In step S101, the current side collision risk of the vehicle is detected.

[0036] It can be understood that the vehicle can obtain the parameters such as the direction of the oncoming vehicle and the speed of the oncoming vehicle through the external sensors, thereby detecting the current side collision risk of the vehicle. The side collision risk can be divided into low risk, medium risk and high risk. The division of the side collision risk will be described in detail below.

[0037] In actual execution, the vehicle can obtain the parameters such as the direction of the oncoming vehicle and the speed of the oncoming vehicle through external sensors such as blind filling radar and vehicle-mounted camera, thereby detecting the current side collision risk of the vehicle, providing a data basis for vehicle collision prevention measures, facilitating collision warning in advance, improving safety protection level, and enhancing driving experience.

[0038] Optionally, in an embodiment of the present application, at least one blind filling radar is arranged at the front fender of the vehicle. The current side collision risk of the vehicle is detected by identifying the current scene of the vehicle, and when the current scene is a low-speed scene with an actual speed less than a preset speed, the current side collision risk is determined based on the time to collision calculated by the at least one blind filling radar.

[0039] It can be understood that the vehicle has different side collision risks in different scenarios. When the vehicle speed is less than a certain speed, such as 3 km / h, it can be identified that the vehicle is in a low-speed scenario, including the vehicle being at a standstill or braking and starting, and there is a collision risk between the vehicle and a crossing vehicle, such as a bicycle, an electric vehicle, and a car.

[0040] Specifically, the embodiment of the present application can first measure the vehicle speed by a speed sensor to identify the current scenario of the vehicle. When the current scenario is a low-speed scenario in which the actual speed is less than a certain speed, such as 3 km / h, the embodiment of the present application can capture and determine whether the vehicle has a side collision risk by an external sensor, such as a blind filling radar, calculate the TTC (Time to Collision) based on at least one blind filling radar, and calculate whether the collision position will be the front row or the rear row of the vehicle.

[0041] For example, if the TTC is less than or equal to 2s, it is determined that the collision risk level of the vehicle and the crossing vehicle is high risk; if the TTC is greater than 5s, it is determined that the collision risk level of the vehicle and the crossing vehicle is low risk. The preset speed and the preset TTC can be set by those skilled in the art according to the actual situation, and are not limited in particular.

[0042] Of course, in other embodiments, the embodiment of the present application can also capture and determine whether the vehicle has a side collision risk by an external sensor, such as a vehicle-mounted camera or a combination of a vehicle-mounted camera and a blind filling radar, and calculate the TTC and the predicted collision position.

[0043] The embodiment of the present application can identify the scenario of the vehicle and determine the current side collision risk by calculating the time to collision by an external sensor, thereby improving the accuracy of detecting the side collision risk, improving the driving safety performance of the vehicle, and enhancing the driving experience of the vehicle.

[0044] In step S102, it is determined whether the current side collision risk is greater than a preset risk.

[0045] It can be understood that when the actual side collision risk is greater than the preset risk, it can be determined that the current vehicle and the crossing vehicle have a collision risk on the driving path, thereby providing a basis for subsequent execution of the seat pre-lifting action.

[0046] Specifically, when the current side collision risk is greater than a certain risk, such as a low risk, the embodiment of the present application can output a judgment signal to the lifting adjustment device to prepare for the execution of the seat pre-lifting action; when the current side collision risk is less than or equal to a certain risk, such as a low risk, the embodiment of the present application can not input the judgment signal to the lifting adjustment device, thereby combining the active safety technology with the passive safety technology to improve the comprehensive safety protection level of the vehicle.

[0047] In step S103, if the current side collision risk is greater than the preset risk, the lifting adjustment device is controlled to perform a pre-lifting action on the vehicle seat on the corresponding risk side, and when a collision is detected, the lifting adjustment device after the pre-lifting action is controlled to raise the height of the seat collision side of the vehicle seat on the corresponding risk side, so that the vehicle seat assumes a protective position in which the base bears the collision.

[0048] It can be understood that when a collision occurs, in order to make the driver as far away from the collision area as possible to reduce the collision contact area, the seat base should bear as much of the collision area as possible. The embodiment of the present application can raise the height of the collision side seat to make the seat assume a protective position in which the base bears the collision, thereby reducing the damage caused by the collision.

[0049] In actual implementation, the embodiment of the present application can control the lifting adjustment device to perform a pre-lifting action of the seat when it is determined that the current side collision risk is greater than a certain risk, such as a low risk. When a collision is detected by a collision sensor, the embodiment of the present application can raise the height of the collision side vehicle seat by the lifting adjustment device, so that the vehicle seat assumes a protective position in which the base bears the collision, thereby making the driver away from the collision area, reducing the collision contact area, reducing the damage caused by the collision, improving the overall safety protection level of the vehicle, and enhancing the user driving experience.

[0050] Optionally, in an embodiment of the present application, when the lifting adjustment device is a hydraulic device, controlling the lifting adjustment device to perform a pre-lifting action on the vehicle seat on the corresponding risk side includes: determining the vehicle seat on the risk side among all vehicle seats of the vehicle; and filling the cylinder of the hydraulic device corresponding to the vehicle seat on the risk side to prepare to raise the height of the seat collision side of the vehicle seat on the corresponding risk side.

[0051] It can be understood that the hydraulic device is composed of a pressurization system, and the pressurized hydraulic device makes the flowing liquid move pressure to different areas to realize the lifting of different areas of the device, so the cylinder of the hydraulic device needs to be filled before use.

[0052] Specifically, the lifting adjustment device in the embodiment of the present application can be a hydraulic device. When controlling the lifting adjustment device to perform a pre-lifting action on the vehicle seat on the corresponding risk side, the lifting adjustment device can identify and determine the vehicle seat on the risk side among all vehicle seats through an external sensor, and fill the cylinder of the hydraulic device corresponding to the vehicle seat on the risk side to prepare to raise the height of the collision side vehicle seat when a collision occurs.

[0053] Of course, in other embodiments, the lifting adjustment device can be a pneumatic device. The pneumatic device uses gas such as air or pure gas to transmit power by compressing the gas, which is simple in structure, light in weight, easy to install and maintain, and safer than hydraulic systems.

[0054] In actual application, the selection of the lifting adjustment device can be made by a person skilled in the art according to the vehicle model, cost, production planning and other factors, and no specific limitation is made here.

[0055] Optionally, in an embodiment of the present application, while controlling the lifting adjustment device to perform the pre-lifting action on the vehicle seat on the corresponding risk side, it further comprises: generating an optimal collision warning strategy based on the current side collision risk; and controlling at least one acoustic warning device, at least one optical warning device and / or at least one haptic warning device of the vehicle to perform a corresponding collision warning action based on the optimal collision warning strategy.

[0056] It can be understood that after identifying the current collision risk of the vehicle, the embodiment of the present application can generate the corresponding optimal collision warning strategy. In order to accurately convey the collision warning information to the driver, the collision warning can be performed in the form of acoustics, optics and / or haptics.

[0057] In actual execution, after calculating the current side collision risk of the vehicle, the embodiment of the present application can generate the corresponding optimal collision warning strategy. When warning the driver of the collision, the embodiment of the present application can use acoustics, optics and / or haptics, such as acoustic warning through buzzer alarm or voice alarm through loudspeaker, optical warning through instrument panel and indicator light flashing, and haptic warning through seat vibration or steering wheel vibration, thereby improving the intelligence of the vehicle and enhancing the driving safety performance of the vehicle.

[0058] For example, the embodiment of the present application can perform acoustic warning through buzzer alarm, wherein the embodiment of the present application can adjust the frequency of the buzzer according to the calculated pre-crash time, such as setting the buzzer to a higher frequency when the pre-crash time is shorter, so as to alert the driver of the risk of pre-crash and handle the collision risk in time.

[0059] Optionally, in an embodiment of the present application, before lifting the height of the seat collision side of the vehicle seat on the corresponding risk side, it further comprises: identifying the actual collision level of the vehicle; and determining that the vehicle has collided when the actual collision level is greater than the preset collision level.

[0060] It can be understood that the actual collision level of the vehicle can be divided into a slight collision, a general collision and a serious collision, the slight collision can be divided when the cross traffic vehicle has stopped before the collision and causes slight damage to the vehicle body, the general collision can be divided when the cross traffic vehicle has a speed lower than 3km / h before the collision and does not cause the vehicle body to move greatly after the collision, and the serious collision can be divided when the cross traffic vehicle has a speed not lower than 30km / h before the collision.

[0061] Specifically, the actual collision level of the vehicle can be identified by the external sensor and the collision sensor, when the actual collision level is greater than a certain level such as the slight collision level, it can be determined that the vehicle has a collision and causes certain damage, the embodiment of the application can perform the action of lifting the vehicle seat on the collision side, so as to make the driver and passenger on the collision side as far away from the collision area as possible, reduce the collision contact area, make the seat base bear more collision area, reduce the harm caused by the collision, thereby improving the intelligent level of the vehicle and enhancing the driving safety performance of the vehicle.

[0062] Optionally, in an embodiment of the application, the preset collision level is the level at which the airbag on the risk side occurs point explosion.

[0063] It can be understood that when a side impact is encountered, the airbag on the side that is impacted will explode, when the vehicle is slightly collided or generally collided, the side airbag will not explode, and when the vehicle is seriously collided, the side airbag will explode.

[0064] In actual implementation process, the preset collision level in the embodiment of the application can be the level at which the airbag on the risk side occurs point explosion, in other embodiments, the preset collision level can be set by the person skilled in the art according to the actual situation, so as to improve the comprehensive safety protection level of the vehicle.

[0065] In combination with Figures 2 to 5 As shown in FIG. 1, the working principle of the seat active control method for vehicle collision in the embodiment of the application is described in detail, which specifically includes the following steps:

[0066] Step S1: scanning and tracking the risk of side collision of the vehicle.

[0067] As Figure 2As shown, this embodiment of the application can obtain parameters such as the oncoming direction and speed of vehicles passing on the side using external sensors such as blind spot radar, vehicle-mounted cameras, or a combination of blind spot radar and vehicle-mounted cameras, thereby detecting the current side collision risk of the vehicle and calculating whether the collision will occur in the front or rear seats of the vehicle. In a low-speed scenario where the actual speed is less than a certain speed, such as 3 km / h, if the TTC is less than or equal to 2 seconds, the collision risk level between the vehicle and the intersecting vehicles is determined to be high risk; if the TTC is greater than 5 seconds, the collision risk level between the vehicle and the intersecting vehicles is determined to be low risk.

[0068] Step S2: Determine if the vehicle has been involved in a side collision and the level of collision intensity.

[0069] like Figure 3 As shown, this application embodiment can determine the side collision and the collision intensity level through a collision sensor. The collision intensity level can be divided into minor collision, general collision, and severe collision. When the vehicles crossing each other have stopped before the collision and the collision results in minor damage to the vehicle body, it can be classified as a minor collision. When the vehicles crossing each other have a speed of less than 3 km / h before the collision and the collision does not cause significant movement of the vehicle body, it can be classified as a general collision. When the vehicles crossing each other have a speed of not less than 30 km / h before the collision, it can be classified as a severe collision.

[0070] Step S3: Perform the action of lifting the seat on the collision side.

[0071] like Figure 4 As shown, this embodiment of the application can identify the collision risk and actual collision level of a vehicle through external sensors and collision sensors. When the collision risk is greater than a certain level, such as a low collision risk, the lifting and adjusting device is controlled to perform a pre-lifting action on the corresponding risk-side vehicle seat. The external sensors identify and determine the vehicle seat on the risk side among all vehicle seats, and fill the cylinder of the hydraulic device corresponding to the risk-side vehicle seat to prepare for raising the height of the collision-side vehicle seat in the event of a collision. When the actual collision level is greater than a certain level, such as a minor collision level, it can be determined that the vehicle has collided and caused some damage. This embodiment of the application can perform the action of raising the collision-side vehicle seat, thereby keeping the occupants on the collision side as far away from the collision area as possible, reducing the collision contact area, allowing the seat base to bear more of the collision area, reducing the damage caused by the collision, thereby improving vehicle intelligence and enhancing vehicle driving safety performance.

[0072] like Figure 5As shown, when the collision side seat lifting action is performed, the embodiment of the application can raise the height of the collision side seat by 5 degrees, keep the driver away from the collision area as far as possible, make the seat base bear more collision area, reduce the harm caused by the collision, and at the same time, not affect the spacing between the seats, ensure the comfort in the cockpit, and improve the comprehensive safety protection level of the automobile.

[0073] According to the vehicle collision seat active control method provided by the embodiment of the application, the active safety and passive safety technologies can be combined, the current side collision risk can be detected through an external sensor, the seat can be pre-lifted when it is judged that there is a collision risk, and the height of the collision side of the seat can be raised when the collision occurs, so that the driver reduces the contact with the collision object, and the comprehensive safety protection level of the vehicle is improved. Therefore, the technical problems in the related art that the passive safety protection is focused on the front collision, and it is difficult to be applied to various safety working conditions of the vehicle driving, so that the comprehensive safety protection level of the vehicle is low are solved.

[0074] Secondly, the vehicle body controller provided by the embodiment of the application is described with reference to the accompanying drawings.

[0075] Figure 6 is a block schematic diagram of the vehicle body controller of the embodiment of the application.

[0080] Optionally, in an embodiment of the application, the control module 300 includes a determination unit and a filling unit.

[0081] The determination unit is configured to determine the vehicle seat of the risk side among all the vehicle seats of the vehicle.

[0082] The filling unit is configured to fill the cylinder of the hydraulic device corresponding to the vehicle seat of the risk side, so as to prepare to raise the height of the collision side of the corresponding risk side of the vehicle seat.

[0083] Optionally, in an embodiment of the present application, the detection module 100 comprises an identification unit and a calculation unit.

[0084] The identification unit is configured to identify a current scenario in which the vehicle is located.

[0085] The calculation unit is configured to determine a current side collision risk based on a time to collision calculated by the at least one blind-spot radar when the current scenario is a low-speed scenario in which an actual speed is less than a preset speed.

[0086] Optionally, in an embodiment of the present application, the vehicle body controller 10 further comprises an identification module and a determination module.

[0087] The identification module is configured to identify an actual collision level of the vehicle.

[0088] The determination module is configured to determine that the vehicle is in collision when the actual collision level is greater than a preset collision level.

[0089] Optionally, in an embodiment of the present application, the preset collision level is a level at which a risk side airbag explodes.

[0090] Optionally, in an embodiment of the present application, the control module 300 further comprises a generation unit and an execution unit.

[0091] The generation unit is configured to generate an optimal collision warning strategy based on the current side collision risk.

[0092] The execution unit is configured to control at least one acoustic warning device, at least one optical warning device, and / or at least one haptic warning device of the vehicle to perform a corresponding collision warning action based on the optimal collision warning strategy.

[0093] It should be noted that the aforementioned description of the seat active control method embodiment for vehicle collision also applies to the vehicle body controller of this embodiment, which will not be described here again.

[0094] According to the vehicle body controller provided in the embodiments of the present application, the embodiments of the present application can combine active safety and passive safety technologies, detect a current side collision risk through an external sensor, perform a pre-lifting action on a seat when it is determined that there is a collision risk, and raise the height of the collision side of the seat when a collision occurs, thereby reducing the contact of the driver and the passenger with a collision object and improving the comprehensive safety protection level of the vehicle. Thus, the technical problem that related technologies focus on passive safety protection for frontal collisions and lack of applicability to various safety working conditions of vehicle driving, resulting in a low comprehensive safety protection level of the vehicle, is solved.
