Description

Technical Field

[0001] The present invention belongs to the technical field of automatic assisted driving, and particularly relates to an overtaking safety control method, device, equipment, medium and product. Background Art

[0002] The statements in this part only provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] An Adaptive Cruise Control (ACC) system can automatically adjust the vehicle speed according to the road conditions ahead and the traffic flow. If the road ahead is clear and there are no vehicles, the vehicle will travel at the cruise speed set by the driver; if a vehicle or obstacle appears ahead, the system will automatically reduce the vehicle speed; when the road conditions permit, it will automatically accelerate back to the set cruise speed. During the acceleration process, it is very likely to overtake the vehicle in the adjacent lane. Assuming there is a vehicle in the left fast lane, since this vehicle may change lanes to the current lane at any time, if the current vehicle under the control of the cruise system overtakes, it may collide with the lane-changing vehicle. Therefore, under the control of the cruise system, the driver needs to keep observing and take over the control when necessary.

[0004] There are methods in the prior art for monitoring the behavior of vehicles in adjacent lanes. Usually, after identifying the vehicle in the adjacent lane, its motion trajectory is tracked, and then it is judged whether it has the intention to change lanes. However, this monitoring method has a high computational complexity and cannot meet the real-time requirements when the vehicle is traveling at a high speed under the control of the automatic cruise system. Summary of the Invention

[0005] To overcome the above-mentioned deficiencies of the prior art, the present invention provides an overtaking safety control method, device, equipment, medium and product, which can ensure the following-distance safety when the vehicle is traveling at a high speed under the control of the adaptive cruise control system without the driver's intervention at all.

[0006] To achieve the above object, the first aspect of the present invention provides the following technical solution:

[0007] An overtaking safety control method includes the following steps:

[0008] When the vehicle is under the control of the adaptive cruise control system and the vehicle speed exceeds the set vehicle speed threshold, continuously monitor whether there is any other vehicle ahead in the adjacent fast lane;

[0009] If there is a vehicle ahead in the adjacent fast lane and the vehicle speed of the current vehicle is greater than the vehicle speed of the vehicle ahead in the adjacent fast lane, judge whether the conditions for inhibiting overtaking are met. If so, trigger the overtaking inhibition control; the overtaking inhibition control specifically is to control the vehicle speed to keep a certain distance from the vehicle ahead in the adjacent fast lane.

[0010] In some embodiments, the adjacent fast lanes are adjacent fast lanes in the same-direction lanes.

[0011] In some embodiments, determining whether the conditions for suppressing overtaking are met specifically includes: real-time monitoring whether there are other vehicles ahead on the current lane; if there is no vehicle ahead on the current lane, triggering overtaking suppression control; if there is a vehicle ahead on the current lane and the speed of the current vehicle is less than or equal to the speed of the vehicle ahead on the current lane, triggering overtaking suppression control; if the speed of the current vehicle is greater than the speed of the vehicle ahead on the current lane and the speed of the vehicle ahead on the adjacent fast lane is less than the speed of the vehicle ahead on the current lane, triggering overtaking suppression control; if the speed of the current vehicle is greater than the speed of the vehicle ahead on the current lane and the speed of the vehicle ahead on the adjacent fast lane is greater than the speed of the vehicle ahead on the current lane, not triggering overtaking suppression control.

[0012] In some embodiments, during the overtaking suppression control process, the speed of the vehicle ahead in the adjacent fast lane is monitored in real time. If the vehicle ahead drives out of its lane or accelerates to a speed greater than the current vehicle, and there are no other vehicles driving in front of the current vehicle on that lane and with a speed lower than the current vehicle for a continuous period of time, the overtaking suppression control is cancelled.

[0013] In some embodiments, when the overtaking suppression control is triggered, a driver is prompted that the overtaking suppression control function has been enabled; when a set action is received, the overtaking suppression control is cancelled.

[0014] In some embodiments, after the overtaking suppression control is cancelled when a set action is received, during driving, the vehicle conditions in the adjacent fast lane are monitored in real time. When the vehicle ahead is overtaken, if there are other vehicles within a certain distance on the adjacent fast lane, the vehicle is recorded as the new vehicle ahead. If the speed of the current vehicle is greater than the speed of the vehicle ahead in that lane, even if the conditions for overtaking the vehicle ahead on the adjacent fast lane are not met, the overtaking suppression control is not triggered.

[0015] The second aspect of the present invention provides an overtaking safety control device, including:

[0016] An adjacent lane monitoring module configured to, when the vehicle is under the control of the adaptive cruise control system and the vehicle speed exceeds a set speed threshold, monitor in real time whether there are other vehicles ahead on the adjacent fast lane;

[0017] An overtaking suppression control module configured to, if there is a vehicle ahead on the adjacent fast lane and the speed of the current vehicle is greater than the speed of the vehicle ahead on the adjacent fast lane, determine whether the conditions for suppressing overtaking are met. If so, trigger overtaking suppression control; the overtaking suppression control specifically is to control the vehicle speed to maintain a certain distance from the vehicle ahead on the adjacent fast lane.

[0018] The third aspect of the present invention provides an electronic device, including a processor and a memory, where computer instructions are stored on the memory. When the computer instructions are executed by the processor, the electronic device executes the method described above.

[0019] The fourth aspect of the present invention provides a computer-readable storage medium, on which a computer program is stored. When the program is executed by a processor, the method described above is implemented.

[0020] The fifth aspect of the present invention provides a computer program product, which includes a computer program. When the computer program is executed by a processor, the method described above is implemented.

[0021] The above one or more technical solutions are particularly applicable to the high-speed driving conditions of a vehicle under the control of an adaptive cruise system. By only monitoring the vehicle speed of itself, the vehicle in front on the current lane, and the vehicle in front on the adjacent fast lane, when the vehicle speed of the vehicle in front on the adjacent fast lane is slower than the vehicle speed of the vehicle itself, it is considered that there is a potential collision risk and the overtaking condition is not met, and overtaking inhibition is performed. Even if the driver does not intervene at all, the driving safety can be ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Instead, these embodiments are provided to more thoroughly and completely understand the present application. It should be understood that the drawings and embodiments of the present application are only for exemplary purposes and are not used to limit the protection scope of the present application.

[0030] In the description of the embodiments of the present application, the term "including" and its similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "at least partially based on".

[0031] It can be understood that the Adaptive Cruise Control (ACC) system is usually turned on during periods when the traffic flow is small and the driving is smooth on highways or urban expressways. In this case, the vehicle speed is generally very fast. When the distance between the vehicle and the vehicle in front increases and does not exceed the set speed of the Adaptive Cruise Control (ACC) system, if the distance between the vehicle and the vehicle in front in the current lane increases or there is no vehicle in front within the field of vision (for example, the vehicle in front changes lanes), the vehicle will accelerate to maintain a relatively stable distance from the vehicle in front. During this process, assuming that there is a vehicle driving in the adjacent fast lane, there will be a collision risk if the judgment is not timely. The trajectory prediction methods of existing vehicles have a large amount of computation and are not applicable to the high-speed driving conditions of vehicles when the Adaptive Cruise Control (ACC) system is turned on.

[0032] To solve the above problems, one or more embodiments of the present invention provide an overtaking safety control method applicable to the high-speed driving conditions of vehicles under the control of the ACC system. By only monitoring the vehicle speeds of itself, the vehicle in front in the current lane, and the vehicle in front in the adjacent fast lane, when the speed of the vehicle in front in the adjacent fast lane is slower than the vehicle speed of itself, it is considered that there is a potential collision risk, and then according to the driving conditions of the vehicle in the current lane, it is comprehensively judged whether to perform overtaking inhibition, ensuring driving safety. When there is no vehicle in the adjacent fast lane that is slower than the vehicle speed of itself, the overtaking inhibition is naturally lifted. Based on this, in the high-speed driving conditions of vehicles when the ACC system is controlled, even if the driver does not perform any operation, the collision risk can be avoided. Of course, if the driver subjectively determines that overtaking is safe at this time, the inhibition can be cancelled by setting actions such as stepping on the accelerator to overtake the vehicle in front in the adjacent fast lane.

[0033] The above method is applied to an Advanced Driving Assistance System (hereinafter referred to as ADAS), which is respectively connected to a perception system, a motion execution mechanism, and an in-vehicle information display and entertainment system. Among them, the driving assistance controller is the decision-making center of the advanced driving assistance system, receiving and processing the target and environmental information of sensors, and combining the vehicle motion information and driver intention on the bus to complete various assisted driving functions. The assisted driving functions involved in one or more embodiments of the present invention are mainly: Adaptive Cruise Control (ACC). The perception system consists of millimeter-wave radars, cameras, etc. The millimeter-wave radars are located at the center of the front end of the vehicle and at the four corners of the vehicle body, and the cameras are located at the center of the front windshield and around the vehicle body, responsible for sensing and identifying information such as the environmental road conditions, other traffic participants, and obstacles. When the system is running, the intelligent driving sensors send this environmental and target data to the driving assistance controller. In one or more embodiments of the present invention, the camera located under the front windshield is mainly used to dynamically capture the road traffic speed limit information, process it into structured information, and provide it to the decision-making center. The adaptive cruise control system will automatically compare the currently set vehicle speed with the identified speed limit value. If the set vehicle speed is higher than the speed limit value, the system will prompt the driver to confirm whether to adjust the vehicle speed. After the driver confirms, the system will automatically adjust the vehicle speed to the speed limit value. The motion execution mechanism consists of various electronic and mechanical units that control the longitudinal and lateral motion of the whole vehicle, including: Electronic Stability Control (ESC), Electric Power Steering (EPS), Engine Control Unit (ECU), Transmission Control Unit (TCU), Vehicle Control Unit (VCU), Inertial Measurement Unit (IMU), etc. The execution mechanism can not only receive the vehicle control commands issued by the upper-level assisted driving system, such as acceleration requests, braking requests, steering wheel angle requests, etc., and the actuator responds to these requests, but also send the vehicle motion information to the bus to complete the longitudinal motion control of the vehicle by the driver or the assisted driving system. The in-vehicle information entertainment system (hereinafter referred to as IVI, In-Vehicle Infotainment) consists of a host, an instrument, a central control display screen, a combination switch, etc., providing a human-vehicle interaction interface for the driver, displaying the vehicle status and traffic information. The driver can directly operate the buttons and soft switches on the combination switch or the central control touch screen to control the opening and closing of various electrical functions of the vehicle body.

[0034] Specifically, the above overtaking safety control method, such as Figure 1 shown, specifically includes the following steps:

[0035] When the vehicle is under the control of the adaptive cruise control system and the vehicle speed exceeds the set vehicle speed threshold, continuously monitor whether there is any other vehicle in front on the adjacent fast lane;

[0036] If there is a vehicle ahead in the adjacent fast lane, and the current vehicle speed is greater than the speed of the vehicle ahead in the adjacent fast lane, determine whether the conditions for suppressing overtaking are met. If so, trigger overtaking suppression control; the overtaking suppression control specifically controls the vehicle speed so that it maintains a certain distance from the vehicle ahead in the adjacent fast lane.

[0037] The adjacent fast lane refers only to the adjacent fast lane in the same direction lane. The set speed threshold is 80 kph, or other values, which are not limited here.

[0038] Based on this, when the vehicle speed is very high and is under the control of the adaptive cruise control system, if the vehicle is in the slow lane, if there is a target in front of the adjacent fast lane (the left lane in right-hand driving conditions and the right lane in left-hand driving conditions), and the vehicle speed is higher than the target in the adjacent fast lane, it is considered that there is a potential risk of collision with the vehicle in front, that is, the conditions for suppressing overtaking are met, and driving safety is guaranteed by suppressing overtaking.

[0039] The overtaking suppression control aims to keep a certain distance from the preceding vehicle in the adjacent fast lane, maintain the current vehicle speed or control the vehicle to decelerate, and the deceleration during deceleration is based on ensuring the comfort of the passengers.

[0040] As a specific implementation method, the road conditions ahead of the vehicle in the current lane are combined to determine whether the conditions for suppressing overtaking are met. Specifically, if Figure 2 As shown, if the current vehicle speed is greater than the speed of the vehicle in front of the adjacent fast lane, it is determined that whether there are other vehicles in front of the current lane in real time; if there is no vehicle in front of the current lane, the overtaking suppression control is triggered; if there is a vehicle in front of the current lane, and the current vehicle speed is less than or equal to the speed of the vehicle in front of the current lane, the overtaking suppression control is triggered; if the current vehicle speed is greater than the speed of the vehicle in front of the current lane, and the speed of the vehicle in front of the adjacent fast lane is less than the speed of the vehicle in front of the current lane, the overtaking suppression control is triggered.

[0041] During the overtaking suppression control process, the speed of the preceding vehicle in the adjacent fast lane is monitored in real time. If the preceding vehicle leaves the adjacent fast lane, or accelerates to a speed greater than the current vehicle, and no other vehicle in the adjacent fast lane drives in front of the current vehicle and has a lower speed than the current vehicle for a period of time, the overtaking suppression control is released. The vehicle will drive normally under the control of the adaptive cruise system. For example, if the current vehicle speed is 80kph and the speed of the preceding vehicle in the left lane is less than 80kph, WSOS will continue to control the vehicle to drive at a speed of 80kph and overtake the preceding vehicle on the left.

[0042] Based on this, when the vehicle is under the control of the adaptive cruise control system, the driver can ensure following vehicle safety without any action. During the overtaking inhibition control process, when the vehicle in the adjacent fast lane in front accelerates or changes lanes, and there are no other vehicles driving in front of the host vehicle in the adjacent fast lane and the speed is lower than that of the host vehicle, the overtaking inhibition control function is naturally cancelled.

[0043] Of course, if the vehicle in front in the adjacent fast lane maintains a low speed, neither accelerating nor changing lanes, or there are many vehicles in the adjacent fast lane, and after the vehicle in front accelerates or leaves the lane, there are other vehicles driving in front of the host vehicle and the speed is lower than that of the host vehicle, then the overtaking inhibition control will continue to be executed, and the situation of driving at a low speed for a long time may be faced, affecting the riding experience. Therefore, when the overtaking inhibition control is triggered, the driver is prompted that the overtaking inhibition control function has been activated; when a set action is received, the overtaking inhibition control is cancelled. That is, during the overtaking inhibition control process, when the driver determines that safe overtaking is possible, this function can be manually cancelled.

[0044] It can be understood that the prompt message that the overtaking inhibition control function has been activated can be displayed via the in-vehicle infotainment system, for example, displayed on the instrument panel or the center control display screen. As an example, if the overtaking inhibition control is recorded as a function as the wrong side overtaking suppression function (WSOS for short), when the overtaking inhibition control is triggered, the instrument panel or the center control display screen can prompt that the "WSOS function has been triggered". The set action for cancelling the overtaking inhibition control can be stepping on the accelerator or operating the set button on the center control display screen, etc., which is not specifically limited herein.

[0045] Since there may be other vehicles in front of the vehicle in front in the adjacent fast lane with a speed lower than that of the current vehicle, that is, there may be a vehicle fleet of two or more vehicles in front in the adjacent fast lane. If the driver determines that safe overtaking is possible at this time and executes the set action, it is defaulted that the entire vehicle fleet in the adjacent fast lane can be overtaken. Specifically, after manually cancelling the overtaking inhibition control, during the overtaking process, the vehicle conditions in the lane are monitored in real time. When overtaking the vehicle in front, if there are other vehicles in the lane within a certain distance, the vehicle is recorded as the new vehicle in front. If the speed of the current vehicle is greater than the speed of the vehicle in front in the adjacent fast lane and the conditions for overtaking the vehicle in front in the adjacent fast lane are met, the overtaking inhibition control is not triggered. Under the control of the adaptive cruise system, the vehicle can overtake multiple vehicles in front in the adjacent fast lane that are relatively close to each other, avoiding frequent intervention by the driver.

[0046] For ease of understanding, the following examples illustrate the triggering and release process of overtaking suppression control based on different driving scenarios of the vehicle. Prerequisites: The ACC function is triggered and the vehicle speed is ≥ 80kph, and the overtaking suppression control function (WSOS function) is turned on.

[0047] Scenario 1: There is a car ahead of you in the lane and a car ahead of you in the left adjacent lane. Figure 3 shown.

[0048] (1) When the speed of the vehicle in front of you in the same lane is greater than or equal to your own speed, and the speed of the vehicle in front of you in the left lane is greater than or equal to your own speed, the WSOS function will not be triggered and ACC will control the vehicle to travel at the set speed;

[0049] (2) When the speed of the vehicle in front of you in the same lane is less than your own speed, and the speed of the vehicle in front of you in the left lane is greater than your own speed, the WSOS function will not be triggered, and ACC will control the vehicle to follow the vehicle in front of you in the same lane;

[0050] (3) When the speed of the vehicle in front of you in the same lane is greater than or equal to your own speed and the speed of the vehicle in front of you in the left lane is less than your own speed, the WSOS function is triggered and ACC will control the vehicle to decelerate comfortably to follow the vehicle in front of you in the left lane and maintain a certain distance. At the same time, the instrument panel displays "WSOS function has been triggered" and the color of the vehicle in front of you in the left lane changes from gray to blue (the color is defined by the HMI).

[0051] If the vehicle ahead in the left lane leaves or accelerates to a speed exceeding that of your vehicle, and there is no other vehicle in the left lane driving in front of your vehicle and with a slower speed than your vehicle, the WSOS function will be released.

[0052] At this time, if the driver steps on the accelerator to actively overtake the vehicle in the left lane, the WSOS function is released and the vehicle in the left lane of the instrument turns gray; during the overtaking of the vehicle in the left lane, if there is a vehicle in front of the vehicle, the WSOS function will not be triggered (even if the driver releases the accelerator pedal), and the vehicle in the left lane of the instrument will always remain gray. After overtaking the vehicle in the left lane, if there is no vehicle in the left lane with a speed lower than the vehicle in front for 10 consecutive seconds, it is considered that the overtaking is completed and the next round of monitoring begins.

[0053] (4) When the speed of the vehicle in front of you in the same lane is less than your own speed, the speed of the vehicle in front of you in the left lane is less than your own speed, and the speed of the vehicle in front of you in the same lane is less than the speed of the vehicle in front of you in the left lane, the WSOS function will not be triggered and ACC will control the vehicle to follow the vehicle in front of you in the same lane;

[0054] (5) When the speed of the vehicle in front of you in the same lane is lower than that of your vehicle, the speed of the vehicle in front of you in the left lane is lower than that of your vehicle, and the speed of the vehicle in front of you in the same lane is higher than that of the vehicle in front of you in the left lane, the WSOS function is triggered and ACC will control the vehicle to decelerate comfortably to follow the vehicle in front of you in the left lane and maintain a certain distance; the instrument panel and the driver stepping on the accelerator to overtake are the same as in the above situation (3).

[0055] Scenario 2: There is no vehicle in front on the current lane, and there is a vehicle in front on the adjacent left lane, as Figure 4 shown.

[0056] (1) When the speed of the vehicle in front on the left lane ≥ the speed of the own vehicle, the WSOS function is not triggered, and ACC will control the vehicle to travel at the set speed;

[0057] (2) When the speed of the vehicle in front on the left lane < the speed of the own vehicle, the WSOS function is triggered, and ACC will control the vehicle to decelerate comfortably and follow the vehicle in front on the left lane while maintaining a certain distance; The instrument and the driver stepping on the accelerator to overtake are the same as the situation (3) in Scenario 1 above.

[0058] During the period when WSOS is triggered, if a vehicle appears in front on the own lane, it will be executed according to Scenario 1.

[0059] Scenario 3: There is no vehicle in front on the adjacent left lane, and there is a vehicle in front on the left cross lane, as Figure 5 shown.

[0060] When there is no vehicle in front on the adjacent left lane and there is a vehicle in front on the left cross lane (regardless of same direction or oncoming), the WSOS function is not triggered, and ACC controls the vehicle to travel at the set speed;

[0061] When a vehicle appears in front on the adjacent left lane (it can be that a vehicle on the left cross lane changes lanes to the left lane), it will be executed according to Scenario 2.

[0062] Scenario 4: The left lane is an oncoming lane, as Figure 6 shown.

[0063] The vehicle in the oncoming lane will not trigger the WSOS function, and ACC will control the vehicle to travel at the set speed or follow the vehicle in front on the current lane.
