Description

Technical Field

[0002] In recent years, the number of cars owned by Chinese households has steadily increased, objectively increasing road safety risks. Car collisions are the primary manifestation of many traffic accidents. Therefore, car traffic safety has become a crucial component of public safety. Car traffic safety encompasses both active and passive safety. Active safety refers to a vehicle's ability to prevent accidents before they occur, by automatically slowing down by identifying potential hazards or, when faced with unexpected circumstances, by maneuvering the vehicle to avoid collisions. Passive safety refers to a vehicle's ability to protect occupants and pedestrians, preventing or minimizing injury, when an unavoidable traffic accident occurs.

[0003] Currently, automotive collision protection devices used to achieve passive safety functions primarily consist of bumpers and underbody guards. These devices are typically mechanically connected or mounted using other counterweight structures. In the event of a collision, the driver applies the brakes to stop the vehicle, while the collision protection devices deform to absorb a small amount of energy, effectively reducing the damage caused by the collision. However, due to the long driver reaction time and vehicle brake response time, significant damage can be caused to the impacted object and vehicle. Furthermore, if the driver fails to stop the vehicle immediately, secondary damage can occur. Summary of the Invention

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0042] The embodiment of the present application provides a kind of automobile collision protection control method, device, equipment and readable storage medium, it can solve the problem that the being collided body and vehicle damage are big and easy to cause secondary injury due to the reaction time of driver and vehicle braking response time is long in the related art.

[0043] To achieve the above object, the general idea of the present application is as follows:

[0044] An automobile collision protection control method, the method comprises the following steps:

[0045] Step S10: obtain the real-time displacement amount of displacement sensor module fixed on the anti-collision device;

[0046] Step S20: determine whether the real-time displacement amount is greater than displacement amount threshold;

[0047] Step S30: if the real-time displacement amount is greater than displacement amount threshold, control power assembly to stop output power and control brake system emergency brake;

[0048] Step S40: obtain the real-time vehicle speed of vehicle, and determine whether the real-time vehicle speed is zero;

[0049] Step S50: if the real-time vehicle speed is zero, control vehicle to be in parking state and locking state.

[0050] The embodiments of the present application are further described in detail below in conjunction with the drawings.

[0051] Referring to Figure 1 And Figure 2 The embodiment of the present application provides an automobile collision protection control method, comprising the following steps:

[0052] Step S10: obtain the real-time displacement amount of displacement sensor module fixed on the anti-collision device;

[0053] Exemplarily, it should be understood that the displacement sensor module in the embodiment is a sensor that can reflect whether the vehicle collides through its deformation amount, which can be a strain displacement sensor, an inductive displacement sensor or a Hall sensor. The specific type of displacement sensor can be determined according to actual needs, which is not limited here.

[0054] It should be noted that the displacement sensor module is installed on the fixed end of the front and rear anti-collision devices of the vehicle, and the sensing end of the displacement sensor module should be arranged and installed on the movable end of the anti-collision device. It can be connected to the HCU (Hybrid Control Unit, hybrid vehicle controller) through the CAN (Controller Area Network, controller area network) line, so that the vehicle controller HCU can determine the real-time displacement of the displacement sensor module according to the displacement signal transmitted by the displacement sensor module, and can automatically control the power output of the vehicle power system and the emergency braking action of the braking system through the real-time displacement.

[0055] Further, the displacement sensor module includes a first displacement sensor and a second displacement sensor, the first displacement sensor is fixedly arranged on the anti-collision device at the front of the vehicle, and the second displacement sensor is fixedly arranged on the anti-collision device at the rear of the vehicle. Preferably, the displacement sensor module includes four displacement sensors, two of which are fixedly arranged on the anti-collision device at the front of the vehicle, and the other two are fixedly arranged on the anti-collision device at the rear of the vehicle.

[0056] It can be understood that the vehicle may collide at the front or at the rear. Therefore, in order to monitor whether the vehicle collides at the front and the rear at the same time, displacement sensors can be installed on the front and rear sides of the vehicle. In order to more accurately determine whether the vehicle collides, as shown in Figure 3 The displacement sensors 1 and 2 are arranged on the anti-collision device at the front of the vehicle, and the displacement sensors 3 and 4 are arranged on the anti-collision device at the rear of the vehicle.

[0057] Step S20: determining whether the real-time displacement is greater than the displacement threshold; wherein the displacement threshold is greater than the vibration error displacement;

[0058] It can be understood that when the vehicle controller HCU obtains the real-time displacement of the displacement sensor module through the CAN line, the size relationship between the real-time displacement and the preset displacement threshold A can be used to determine whether the vehicle collides, that is, when the real-time displacement is less than or equal to the displacement threshold A, it indicates that the vehicle does not collide at this time; when the real-time displacement is greater than the displacement threshold A, it indicates that the vehicle has collided at this time, and emergency parking is required.

[0059] It should be noted that the specific setting of the displacement threshold A can be determined according to actual needs, which is not limited here. However, since the vibration of the vehicle can also cause the displacement of the displacement sensor module to change, and this displacement is not caused by the collision of the vehicle, that is, the displacement cannot effectively reflect the true state of the vehicle collision, and thus the vehicle control unit HCU may appear collision misjudgment. Therefore, in order to avoid collision misjudgment caused by vibration, the displacement threshold can be set to be greater than the vibration error displacement, which can represent the true state of the vehicle collision, that is, when the real-time displacement is greater than the displacement threshold, it means that the real-time displacement is caused by the collision of the vehicle and is not related to the vibration of the vehicle, and thus the vehicle control unit HCU can accurately determine whether the vehicle has collided according to the size relationship between the real-time displacement and the displacement threshold.

[0060] Step S30: If the real-time displacement is greater than the displacement threshold, control the power assembly to stop outputting power and control the brake system to emergency brake;

[0061] Exemplarily, in the present embodiment, when the vehicle control unit HCU detects that the real-time displacement is greater than the displacement threshold, it can be determined that the vehicle is in a collision state, at which time a power stop output instruction can be issued to the vehicle power assembly, and an emergency braking instruction can be issued to the brake system, so that the vehicle realizes power stop output and emergency braking, that is, driving power stop output and emergency braking parking can be realized in the shortest time, so as to effectively reduce the damage to the vehicle and the collided body.

[0062] Step S40: Obtain the real-time speed of the vehicle and determine whether the real-time speed is zero;

[0063] Exemplarily, in the present embodiment, after the vehicle control unit HCU controls the power assembly to stop outputting driving power and the brake system to emergency brake and park, the real-time speed of the vehicle also needs to be detected, and whether the vehicle has completed parking is determined according to whether the real-time speed of the vehicle is zero. If the real-time speed is zero, it means that the vehicle has been parked, that is, the vehicle has stopped; if the real-time speed is not zero, it means that the vehicle has not been parked, that is, the vehicle has not stopped, and the brake system needs to be controlled to continue emergency braking so that the vehicle can be in a parked state.

[0064] Step S50: If the real-time speed is zero, control the vehicle to be in a parked state and a locked state.

[0065] Exemplarily, it can be understood that when the real-time vehicle speed is reduced to zero, it indicates that the vehicle is in a parking state, at this time the vehicle control unit HCU will issue an electronic parking instruction to start the electronic parking, so that the vehicle realizes the parking state, thereby ensuring that the vehicle does not slide on the slope and remains stationary to avoid safety accidents. At the same time, the vehicle is locked and is not allowed to continue to move to avoid secondary damage to the collision body and the vehicle.

[0066] Further, the control of the vehicle in the parking state and the locked state comprises:

[0067] When it is detected that the real-time displacement amount of the first displacement sensor and the real-time displacement amount of the second displacement sensor are both greater than the displacement amount threshold, the vehicle is controlled to be in a locked state to prohibit the vehicle from moving forward and moving backward;

[0068] When it is detected that the real-time displacement amount of the first displacement sensor is greater than the displacement amount threshold and the real-time displacement amount of the second displacement sensor is not greater than the displacement amount threshold, the vehicle is controlled to be in a locked state in the forward direction to prohibit the vehicle from moving forward;

[0069] When it is detected that the real-time displacement amount of the first displacement sensor is not greater than the displacement amount threshold and the real-time displacement amount of the second displacement sensor is greater than the displacement amount threshold, the vehicle is controlled to be in a locked state in the backward direction to prohibit the vehicle from moving backward.

[0070] Exemplarily, in the embodiment, the vehicle control unit HCU can determine whether the vehicle is forward collision, backward collision, or both forward and backward collision through the displacement signal. If the vehicle control unit HCU only determines that the displacement sensor 1 is triggered or the displacement sensor 2 is triggered or both the displacement sensor 1 and the displacement sensor 2 are triggered, it indicates that the vehicle is forward collision, at this time the vehicle is controlled to be locked in the forward direction, that is, the vehicle forward gear is controlled to be invalid to prohibit the vehicle from moving forward; if the vehicle control unit HCU only determines that the displacement sensor 3 is triggered or the displacement sensor 4 is triggered or both the displacement sensor 3 and the displacement sensor 4 are triggered, it indicates that the vehicle is backward collision, at this time the vehicle is controlled to be locked in the backward direction, that is, the vehicle reverse gear is controlled to be invalid to prohibit the vehicle from moving backward.

[0071] If the HCU determines that displacement sensor 1 and displacement sensor 3 are triggered at the same time, or displacement sensor 1 and displacement sensor 4 are triggered at the same time, or displacement sensor 2 and displacement sensor 3 are triggered at the same time, or displacement sensor 2 and displacement sensor 4 are triggered at the same time, or all displacement sensors are triggered at the same time, that is, as long as at least one displacement sensor in the front direction and at least one displacement sensor in the rear direction are triggered at the same time, it means that the front and rear directions of the vehicle have collided, and at this time, the front and rear directions of the vehicle are locked, that is, the forward gear and the reverse gear of the vehicle are controlled to be invalid, so as to prohibit the vehicle from moving forward and backward.

[0072] Further, after the step of controlling the vehicle to be in the parking state and the locked state if the real-time vehicle speed is zero, the method further comprises:

[0073] obtaining a first displacement amount of the displacement sensor module at the current time, and determining whether the first displacement amount is greater than a displacement threshold value;

[0074] if the first displacement amount is greater than the displacement threshold value, the vehicle continues to be in the locked state;

[0075] if the first displacement amount is less than or equal to the displacement threshold value, the vehicle is unlocked.

[0076] In an exemplary embodiment, when the vehicle is in the locked state, it can be further determined whether the collision has been removed, that is, after the vehicle is locked, the displacement amount of the displacement sensor module is continuously obtained, and whether the collision has been removed is determined according to the size relationship between the displacement amount and the displacement threshold value. If the displacement amount is still greater than the displacement threshold value at this time, it means that the collision has not been removed, that is, the obstacle has not been removed, and the vehicle lock needs to be maintained to ensure that the vehicle will not move. If the displacement amount is less than or equal to the displacement threshold value, it means that the collision has been removed, that is, the obstacle has been removed, and at this time, the vehicle lock can be released to allow the vehicle to move in the direction of removing the collision.

[0077] Further, if the first displacement amount is less than or equal to the displacement threshold value, the vehicle is unlocked, comprising:

[0078] when the first displacement amount of the first displacement sensor and the first displacement amount of the second displacement sensor are both not greater than the displacement threshold value, the vehicle is unlocked to allow the vehicle to move forward and backward;

[0079] when the first displacement amount of the first displacement sensor is greater than the displacement threshold value and the first displacement amount of the second displacement sensor is not greater than the displacement threshold value, the rearward lock of the vehicle is released to allow the vehicle to move backward;

[0080] When the first displacement amount of the first displacement sensor is not greater than the displacement amount threshold and the first displacement amount of the second displacement sensor is greater than the displacement amount threshold, the vehicle forward locking is released, so that the vehicle can move forward.

[0081] For example, in the embodiment, after the vehicle is locked, when the vehicle control unit HCU only detects that the displacement amounts of the displacement sensor 1 and the displacement sensor 2 are less than or equal to the displacement amount threshold, it indicates that the vehicle forward collision has been released, at this time, the vehicle forward locking can be released, that is, the forward gear function is restored, so that the vehicle can move forward; when the vehicle control unit HCU only detects that the displacement amounts of the displacement sensor 3 and the displacement sensor 4 are less than or equal to the displacement amount threshold, it indicates that the vehicle rear collision has been released, at this time, the vehicle rear locking can be released, that is, the reverse gear function is restored, so that the vehicle can move backward; when the vehicle control unit HCU detects that the displacement sensors 1 to 4 are less than or equal to the displacement amount threshold, it indicates that the vehicle forward and rear collisions have been released, at this time, the vehicle forward and rear lockings can be released, that is, the forward gear and reverse gear functions are restored, so that the vehicle can move forward and backward.

[0082] It can be understood that as long as the displacement amount of one of the forward displacement sensors is greater than the displacement amount threshold, it indicates that the vehicle forward collision has not been released, at this time, the vehicle forward locking needs to be continued to control, so as to prohibit the vehicle from moving forward; similarly, as long as the displacement amount of one of the rear displacement sensors is greater than the displacement amount threshold, it indicates that the vehicle rear collision has not been released, at this time, the vehicle rear locking needs to be continued to control, so as to prohibit the vehicle from moving backward.

[0083] Therefore, through the present application, when a collision occurs, the displacement amount of the displacement sensor can be used to automatically control the power output of the vehicle power system and the emergency braking of the braking system, so as to realize the power output stop and emergency braking in the shortest time, and the vehicle can be automatically locked in time, which not only limits the moving direction of the vehicle, but also prevents the vehicle from continuing to move, so as to avoid secondary damage to the vehicle and the collided body, thereby minimizing the damage to the vehicle and the collided body and improving the user value.

[0094] control the vehicle to be in a locked state to prohibit the vehicle from moving forward when it is detected that the real-time displacement amount of the first displacement sensor is greater than the displacement amount threshold value and the real-time displacement amount of the second displacement sensor is not greater than the displacement amount threshold value;

[0096] Further, the acquisition unit is further configured to acquire a first displacement amount of the displacement sensor module at a current time point.

[0097] The judgment unit is further configured to judge whether the first displacement amount is greater than the displacement amount threshold value.

[0098] The control unit is further configured to keep the vehicle in a locked state if the first displacement amount is greater than the displacement amount threshold value, and release the vehicle from the locked state if the first displacement amount is less than or equal to the displacement amount threshold value.

[0099] Further, the control unit is further specifically configured to:

[0100] release the vehicle from the locked state to enable the vehicle to move forward and backward when the first displacement amount of the first displacement sensor and the first displacement amount of the second displacement sensor are both not greater than the displacement amount threshold value.
