Description

Technical Field

[0001] The present invention relates to the field of vehicle assisted driving, and in particular to a method for switching a driving assistance control mode and related equipment. Background Art

[0002] Adaptive cruise control is a vehicle control system that collects the distance between the vehicle and the vehicle in front based on the information detected by the vehicle-to-vehicle distance sensor, sets a safe distance, and controls the vehicle's speed based on the distance between the vehicle and the vehicle in front and the set safety distance. The system can control the vehicle to maintain a reasonable distance from the vehicle in front, thereby ensuring driving safety.

[0003] Automatic emergency braking uses radar to measure the distance to the vehicle in front or an obstacle, and analyzes the measured distance against the warning distance and safety distance. If the distance between the vehicle and the vehicle in front or an obstacle is less than the warning distance, an alarm will be given. If the distance between the vehicle and the vehicle in front or an obstacle is less than the safety distance, the automatic emergency braking system will automatically activate and brake the car even if the driver does not have time to step on the brake pedal, thereby ensuring safe travel.

[0004] At present, the adaptive cruise mode and automatic emergency braking mode of vehicles have independent functions and only consider driving safety and pursue high safety of vehicles, while ignoring the comfort requirements of passengers on the vehicle. As a result, when the vehicle is switched to the automatic emergency braking mode and emergency braking is performed on the vehicle, on the one hand, the vehicle speed suddenly slows down and drops directly to 0, and the braking is violent, which may cause passengers in the car to collide and create danger. On the other hand, the automatic cruise mode exits at the moment before the vehicle enters the automatic emergency braking mode, accompanied by a pressure relief process. When entering the automatic emergency braking mode, it is pressurized again, causing the vehicle to shake during the switching process. Summary of the invention

[0005] The present invention provides a method for switching a driving assistance control mode and related equipment to solve the problem that during vehicle driving, the vehicle's adaptive cruise control system and the vehicle's automatic emergency braking system do not interact with each other, resulting in the vehicle being judged to have a collision risk and either immediately decelerating at a large deceleration, or experiencing unevenness during the function switching process, thereby affecting the vehicle's comfort.

[0014] Optionally, when the braking operation is not obtained or the braking operation is invalid, the vehicle is switched to an automatic emergency braking mode for emergency braking.

[0015] Optionally, when the braking operation is not obtained or the braking operation is invalid, switching the vehicle to an automatic emergency braking mode for emergency braking includes:

[0016] switching the vehicle to an automatic emergency braking mode when the braking operation is not obtained or the braking operation is invalid;

[0017] The deceleration of the vehicle is adjusted to be greater than or equal to the target deceleration based on the automatic emergency braking mode.

[0018] Optionally, when the braking operation is not obtained or the braking operation is invalid, performing emergency braking by switching the vehicle to an automatic emergency braking mode further includes:

[0019] In case of emergency braking by switching the vehicle to an automatic emergency braking mode, obtaining viewing angle information of the driver of the vehicle at a moment before braking;

[0020] When the viewing angle information matches the target object in the direction of travel of the vehicle, and it is again monitored that the vehicle is in adaptive cruise mode and the target deceleration does not match the vehicle in adaptive cruise mode, the vehicle is switched to automatic emergency braking mode for emergency braking.

[0021] In a second aspect, the present invention further provides a driving assistance control mode switching device, comprising:

[0022] A determination module, used to determine a target deceleration based on the vehicle driving direction detection information and the vehicle's own driving state information;

[0024] A control module is configured to avoid emergency braking by switching the vehicle to an automatic emergency braking mode if the braking operation is effective.

[0025] In a third aspect, the present invention further provides an electronic device, comprising a memory and a processor, wherein the processor is configured to implement the steps of the method for switching the driving assistance control mode as described in any one of the first aspects above when executing a computer program stored in the memory.

[0033] The embodiments will be described in detail below, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following embodiments do not represent all implementation methods consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims. In the several embodiments provided in the embodiments of the present application, it should be understood that the disclosed devices and methods can also be implemented in other ways, and the device embodiments described below are merely exemplary.

[0034] The present application provides a method for switching a driving assistance control mode, such as Figure 1 As shown, including:

[0035] Step S110: Determine the target deceleration based on the vehicle driving direction detection information and the vehicle's own driving state information.

[0036] Exemplarily, the vehicle driving direction detection information can be obtained through a vehicle-mounted image acquisition device and a vehicle radar, the vehicle's own driving status information can be obtained through a vehicle controller, and a target deceleration determination model can be written into the vehicle controller in advance. The target deceleration value can be determined based on the vehicle driving direction detection information and the vehicle's own driving status information in combination with the target deceleration determination model.

[0037] Step S120: When the vehicle is in an adaptive cruise mode and the target deceleration does not match the vehicle being in the adaptive cruise mode, obtaining a braking operation of the vehicle by the driver.

[0038] Exemplarily, the maximum deceleration value of the vehicle in an adaptive cruise mode can be obtained through the vehicle's adaptive cruise system, the target deceleration and the maximum deceleration value of the vehicle in an adaptive cruise mode can be compared, and when the target deceleration is greater than the maximum deceleration value of the vehicle in an adaptive cruise mode, the driver's braking operation on the vehicle can be detected and simultaneously obtained, and the driver's braking operation on the vehicle can be obtained through a vehicle controller, and the braking operation can include starting the vehicle's driving brake and starting the vehicle's parking brake. The wheel force can be monitored through a pressure sensor at the wheel, and when the wheel force increases, it is determined that the driver has braked the vehicle. The pressure in the brake air chamber can also be monitored through a pressure sensor in the brake chamber, and when the pressure increases, it is determined that the driver has braked the vehicle.

[0039] Step S130: When the braking operation is effective, avoid emergency braking by switching the vehicle to an automatic emergency braking mode.

[0040] For example, when the driver initiates a braking operation on the vehicle, it can be determined whether the braking operation is effective by comparing the current deceleration of the vehicle with the target deceleration. If the braking operation is effective, the driver can continue to drive the vehicle to avoid emergency braking by switching the vehicle to automatic emergency braking mode.

[0041] According to some embodiments, the method for switching the driving assistance control mode further includes:

[0042] When the above braking operation is effective, exiting the above adaptive cruise mode;

[0043] Maintain current brake pressure in Adaptive Cruise Mode as above.

[0044] When the driver's braking operation is effective, the adaptive cruise mode is exited and the driver takes back the driving rights of the vehicle, while maintaining the current brake pressure in the above adaptive cruise mode. The driver can further decelerate and brake the vehicle based on the current adaptive cruise mode speed, so that the vehicle can be decelerated smoothly, avoiding the reduction of the vehicle's brake pressure due to exiting the adaptive cruise mode, and the vehicle accelerating and then decelerating under the driver's braking operation, thereby improving the stability and comfort of the vehicle.

[0045] According to some embodiments, the adaptive cruise control mode is an ACC mode, and the automatic emergency braking mode is an AEB mode.

[0046] The above-mentioned ACC mode is a vehicle control mode that collects the distance between the vehicle and the vehicle in front based on the information detected by the vehicle distance sensor, and controls the vehicle speed according to the distance between the vehicle and the vehicle in front and the set safety distance by setting a safety distance. In this mode, the vehicle can be controlled to maintain a reasonable distance from the vehicle in front, thereby ensuring driving safety. The above-mentioned AEB mode is to measure the distance to the vehicle in front or an obstacle through the vehicle radar, analyze the measured distance, the alarm distance, and the safety distance, and issue an alarm when the distance between the vehicle and the vehicle in front or an obstacle is less than the alarm distance. When the distance between the vehicle and the vehicle in front or an obstacle is less than the safety distance, the automatic emergency braking system will automatically start to brake the car even if the driver does not have time to step on the brake pedal, thereby ensuring safe travel.

[0047] According to some embodiments, the vehicle driving direction detection information includes at least one of the type of target object in the vehicle driving direction, the distance between the vehicle and the target object, the speed of the target object and the orientation of the target object relative to the vehicle; the vehicle's own driving status information includes at least one of the speed, acceleration and steering angle of the vehicle.

[0048] Exemplarily, an on-board image acquisition device may be used to capture images of the vehicle's traveling direction. If there is a target object in the vehicle's traveling direction, information about the distance between the vehicle and the target object and the speed of the target object may be collected through an on-board radar and / or the vehicle's inter-vehicle distance sensor. Information about the orientation of the target object relative to the vehicle may be collected through the on-board image acquisition device and / or the on-board radar. Information about the speed, acceleration and steering angle of the vehicle may be collected through a vehicle management system and / or a vehicle controller.

[0049] The maximum deceleration value of the vehicle in the adaptive cruise mode can be determined based on the vehicle driving direction detection information, and the target deceleration of the vehicle can be determined based on the vehicle's own driving state information and the vehicle direction detection information.

[0050] According to some embodiments, the method for switching the driving assistance control mode further includes:

[0051] When the braking operation is not acquired or is invalid, emergency braking is performed by switching the vehicle to an automatic emergency braking mode.

[0052] Exemplarily, the driver's braking operation on the above-mentioned vehicle can be obtained at any time, and the driver's braking operation on the above-mentioned vehicle can be obtained through the vehicle controller. When the vehicle's driving brake and the vehicle's parking brake are not detected, it is determined that the driver has not performed a braking operation on the vehicle. The wheel force can be monitored by the pressure sensor at the wheel. When the wheel force does not increase, it is determined that the driver has not performed a braking operation on the vehicle. The pressure in the brake air chamber can also be monitored by the pressure sensor in the brake chamber. When the pressure does not increase, it is determined that the driver has not performed a braking operation on the vehicle; when the driver performs a braking operation on the vehicle, the wheel force can be monitored by the pressure sensor at the wheel. When the wheel force is less than the above-mentioned target deceleration, it is determined that the above-mentioned braking operation is invalid. The pressure in the brake air chamber can also be monitored by the pressure sensor in the brake chamber. When the pressure in the brake air chamber is less than the above-mentioned target deceleration, it is determined that the above-mentioned braking operation is invalid. When the above-mentioned braking operation is not obtained or the above-mentioned braking operation is invalid, the current braking pressure can be maintained and the vehicle can be switched to the emergency braking mode.

[0053] The driver's braking operation on the above-mentioned vehicle can be obtained at any time. When the above-mentioned braking operation is not obtained or the above-mentioned braking operation is invalid, it can be determined that the driver is unable to achieve safe braking of the vehicle, so the above-mentioned vehicle is switched to the automatic emergency braking mode for emergency braking, which can ensure the safety of the vehicle during driving.

[0054] According to some embodiments, when the braking operation is not obtained or the braking operation is invalid, performing emergency braking by switching the vehicle to an automatic emergency braking mode includes:

[0055] When the braking operation is not obtained or is invalid, switching the vehicle to an automatic emergency braking mode;

[0056] The deceleration of the vehicle is adjusted to be greater than or equal to the target deceleration based on the automatic emergency braking mode.

[0057] The driver's braking operation on the above-mentioned vehicle is obtained within a preset time. If the above-mentioned braking operation is not obtained or the above-mentioned braking operation is invalid, it can be determined that the driver is unable to achieve safe braking of the vehicle. The current braking pressure is maintained instead of reducing the pressure during the switching process. Switching the above-mentioned vehicle to the automatic emergency braking mode can avoid the situation where the vehicle is first depressurized and then increased in pressure during the mode switching process, resulting in violent shaking of the vehicle. At the same time, the deceleration of the above-mentioned vehicle is adjusted to be greater than or equal to the above-mentioned target deceleration, which can ensure that the vehicle can achieve safe braking in the automatic emergency braking mode and ensure the driving safety of the vehicle.

[0058] According to some embodiments, when the braking operation is not obtained or the braking operation is invalid, performing emergency braking by switching the vehicle to an automatic emergency braking mode further includes:

[0059] In the case of emergency braking by switching the vehicle to an automatic emergency braking mode, obtaining the perspective information of the driver of the vehicle at a moment before braking;

[0060] When the viewing angle information matches the target object in the driving direction of the vehicle, and it is again monitored that the vehicle is in adaptive cruise mode and the target deceleration does not match that of the vehicle in adaptive cruise mode, emergency braking is performed by switching the vehicle to automatic emergency braking mode.

[0061] Exemplarily, information on target objects in the direction of travel of the vehicle can be collected through a vehicle-mounted image acquisition device, the driver's field of view can be acquired through a vehicle management system, the viewing angle information of the driver of the vehicle can be determined based on the driver's field of view and the field of view of the vehicle image acquisition device, and the viewing angle information of the driver of the vehicle can be matched with the target objects in the direction of travel of the vehicle through the image processing algorithm of the vehicle management system.

[0062] When the visual angle information of the driver of the vehicle just before braking matches the target object in the driving direction of the vehicle, there is reason to believe that before the vehicle switches to the automatic emergency braking mode, the driver can judge that the vehicle needs to be braked, but because the driver's reaction time is too long or the driver cannot effectively brake the vehicle, it can be considered that the driver does not have the ability to actively perform safe braking. Therefore, when it is monitored again that the vehicle is in the adaptive cruise mode and the target deceleration does not match the vehicle in the adaptive cruise mode, there is no need to obtain the driver's braking operation on the vehicle. Emergency braking can be performed directly by switching the vehicle to the automatic emergency braking mode, which can save braking time and further ensure the driving safety of the vehicle.

[0063] See also Figure 2 , Figure 2 It is a schematic structural diagram of a driving assistance control mode switching device provided in an embodiment of the present application.

[0064] The embodiment of the present application provides a driving assistance control mode switching device 200, which includes: a determination module 201, a collection module 202, and a control module 203, wherein:

[0065] A determination module 201 is used to determine a target deceleration based on the vehicle driving direction detection information and the vehicle's own driving state information;

[0066] The acquisition module 202 is used to obtain the driver's braking operation on the vehicle when the vehicle is in an adaptive cruise mode and the target deceleration does not match the vehicle in the adaptive cruise mode;

[0067] The control module 203 is used to avoid emergency braking by switching the vehicle to an automatic emergency braking mode when the braking operation is effective.

[0068] A driving assist control mode switching device 200 can achieve Figure 1 The various processes implemented in the method embodiment are not described here in detail to avoid repetition. The switching device of the driving assist control mode can determine the target deceleration through the vehicle driving direction detection information and the vehicle's own driving state information, and control the vehicle to switch the control mode according to the above target deceleration, the maximum deceleration value in the adaptive cruise mode and the driver's braking operation information on the vehicle. In this way, the vehicle's adaptive cruise mode and the automatic emergency braking mode can interact to ensure driving safety and improve the comfort of the vehicle.

When the processor 320 executes the computer program 311, the following steps are implemented:

[0072] When the vehicle is in an adaptive cruise mode and the target deceleration does not match the vehicle in the adaptive cruise mode, obtaining a braking operation of the vehicle by the driver;

[0073] In the case where the braking operation is effective, emergency braking is avoided by switching the vehicle to an automatic emergency braking mode.
