Description

Technical Field

[0001] This application relates to the field of autonomous driving technology, and more specifically, to a driving assistance function processing method, device, electronic device, and storage medium. Background Technology

[0002] The activation of the Anti-lock Braking System (ABS) and the Traction Control System (TCS) requires a certain slip ratio to be met. When ABS and TCS are activated, the driver assistance systems cannot be activated or will not operate if they are already activated. If the slip ratio is too high and the activation condition is not met, ABS and TCS will not be activated and the driver assistance systems will not operate, which not only affects driving safety but also reduces the user's experience with the driver assistance systems. Summary of the Invention

[0003] In view of the above problems, this application proposes a driving assistance function processing method, device, electronic device and storage medium.

[0004] In a first aspect, embodiments of this application provide a driving assistance function processing method, the method including obtaining the wheel slip ratio; obtaining the activation state of the driving assistance system; if the activation state is activated, processing the driving assistance function according to a preset condition reached by the wheel slip ratio.

[0005] Secondly, embodiments of this application provide a driving assistance function processing device, the device comprising: a slip ratio acquisition module for acquiring the slip ratio of a wheel; an activation state acquisition module for acquiring the activation state of a driving assistance system; and a processing module for, if the activation state is activated, processing the driving assistance function according to a preset condition reached by the slip ratio of the wheel.

[0006] Thirdly, embodiments of this application provide an electronic device, including: one or more processors; a memory; and one or more application programs, wherein the one or more application programs are stored in the memory and configured to be executed by the one or more processors, and the one or more application programs are configured to perform the driving assistance function processing method provided in the first aspect above.

[0007] Fourthly, embodiments of this application provide a computer-readable storage medium storing program code, which can be invoked by a processor to execute the driving assistance function processing method provided in the first aspect above.

[0008] The solution provided in this application acquires the wheel slip ratio and the activation status of the driving assistance system. If the activation status is "activated," the driving assistance function is processed according to preset conditions based on the wheel slip ratio. By acquiring the slip ratio of each wheel in real time and obtaining the activation status of the driving assistance system at that time, when the driving assistance system is activated, the acquired wheel slip ratio is compared with preset conditions. When the slip ratio reaches different preset conditions, the driving assistance system performs different function activation, switching, and deactivation operations based on the slip ratio, thereby improving the driver's comfort and safety during driving.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0020] Please see Figure 1 , Figure 1 For intelligent vehicles equipped with ABS, TCS, and driver assistance systems, wheel speed sensors on each wheel detect wheel speed pulses. The vehicle's braking control module then calculates the corresponding slip ratio for each wheel. ABS, TCS, and driver assistance functions all operate based on these wheel slip ratios. ABS and TCS are safety features, while driver assistance functions are comfort features. These two types of functions share the same slip ratio range. When the slip ratio is too high but does not meet the ABS or TCS activation threshold, it will affect the user experience of the intelligent driving functions and also compromise safety.

[0021] To address the aforementioned problems, the inventors have proposed a driving assistance function processing method, device, electronic device, and storage medium as provided in the embodiments of this application. This method acquires the slip ratio of each wheel in real time. When the slip ratio does not reach the ABS or TCS activation threshold, the activation state of the driving assistance system is acquired. When the driving assistance system is activated, the acquired slip ratio of each wheel is compared with preset conditions. When the slip ratio reaches different preset conditions, the driving assistance system performs different function activation, switching, and deactivation operations based on that slip ratio, thereby improving the driver's comfort and safety during driving. The specific driving assistance function processing method will be described in detail in subsequent embodiments.

[0022] Please see Figure 2 , Figure 3 , Figure 2 A flowchart illustrating a driving assistance function processing method provided in an embodiment of this application is shown. Figure 3 This illustration shows a schematic diagram of the driving assistance function states under different preset conditions when the driving assistance system is activated, according to one embodiment of this application. In a specific embodiment, the driving assistance function processing method is applied to, for example... Figure 7 The driving assistance function processing device 300 shown and the electronic device equipped with the driving assistance function processing device 300 are shown.

[0023] The following will use an electronic device as an example to illustrate the specific process of this embodiment. The following will focus on... Figure 2 The process shown will be described in detail. The driving assistance function processing method may specifically include the following steps:

[0024] Step S110: Obtain the slip ratio of the wheel.

[0025] In this embodiment, when a tire applies traction or braking force, relative motion occurs between the tire and the ground. The slip ratio is the proportion of slippage in the wheel's motion. In this embodiment, wheel speed sensors installed on the wheel speed detection device can detect the wheel speed pulses of each wheel, and the vehicle's braking control module can then calculate the slip ratio corresponding to each wheel. Taking a vehicle with four wheels as an example, the wheel speed pulses of the four wheels, the overall vehicle speed V, and the slip ratios of the four wheels can be obtained, with the slip ratio of the left front wheel being S. FL The wheel slip ratio of the right front vehicle is S FR The slip ratio of the left rear wheel is S RL The slip ratio S of the right rear wheel RR .

[0026] Step S120: Obtain the activation status of the driving assistance system.

[0027] The activation status of a driver assistance system can include both activated and deactivated states. Driver assistance systems can be activated by a user issuing an activation command, or they can be controlled by an intelligent system. When a certain parameter in the vehicle meets the activation conditions of the driver assistance system, the intelligent system issues an activation command to activate it. Specific activation conditions can be defined according to actual circumstances.

[0028] Step S130: If the activation state is activated, the driving assistance function is processed according to the preset condition of the wheel slip rate.

[0029] When the driving assistance system receives an activation command from the user or intelligent system, it performs various processes such as activation, deactivation, and maintenance of the driving assistance function according to different preset conditions for the slip ratio.

[0030] Specifically, in some embodiments of this application, the driving assistance system is deactivated when the slip ratio of at least one of the wheels is greater than a first preset value.

[0031] Within a certain period, when the driving assistance system detects that the slip rate of at least one wheel exceeds a first preset value, the system will issue relevant commands to the steering wheel or a prompting device. For example, the steering wheel may vibrate to prompt the user to take over the vehicle. The intensity, frequency, and duration of the steering wheel vibration can be defined by the user. The driving assistance system can also prompt the driver to take over the vehicle through an audible alarm device on the vehicle. The decibels, timbre, and duration of the audible alarm are also defined by the user. The intelligent driving assistance system deactivates when the slip rate of at least one wheel exceeds the first preset value. The period duration can also be defined according to the user's needs to improve the user experience.

[0032] For example, within a T1 ms period, the first preset value is S1, when the slip ratio S of the left front wheel is... FL >S1, the vehicle's driver assistance system disengages, and the driver takes control of the vehicle.

[0033] In other embodiments of this application, processing the driving assistance function in accordance with the preset conditions further includes determining the operating state of the driving assistance system when the slip ratio of at least one of the wheels is greater than a second preset value and less than or equal to a first preset value, wherein the second preset value is less than the first preset value. If the navigation driving assistance function is active, the driving assistance system is switched to the cruise assistance function.

[0034] Within a certain period, when the slip ratio of at least one of the wheels is greater than a second preset value and less than or equal to a first preset value, the operating status of the driving assistance system is first determined. The operating status of the driving assistance system may include multiple functions operating simultaneously. For example, the driving assistance system has a navigation driving assistance function (NDA) and a cruise assist function. The navigation driving assistance function can autonomously overtake, change lanes, enter and exit ramps, use ramps, and merge into the main road based on the guidance of the navigation route or the surrounding traffic environment. The cruise assist function can lock onto the vehicle in front in the same lane. After setting a reasonable speed and distance, it can follow the vehicle in front, accelerating or decelerating, stopping, or starting. The cruise assist function includes adaptive cruise control (ACC) and integrated cruise assist (ICA). Adaptive cruise assist can be applied to lower speed driving conditions, such as urban driving conditions, while integrated cruise assist can be applied to higher speed driving conditions, such as highways, where the user can customize the starting speed.

[0035] In this application, when the NDA (Neural Driver Assist) has a higher priority than the cruise assist function, and when the slip ratio of at least one of the wheels is greater than a second preset value and less than or equal to a first preset value, it is necessary to determine whether the NDA or the cruise assist function is active in the driver assistance system. If the NDA is active, the NDA is switched to the cruise assist function, so that the cruise assist function is active.

[0036] Specifically, let the first preset value be S1 and the second preset value be S2. Within the period T2 ms, when S2 FL ≤S1 and S2 RR When the time is ≤S1, switch the high-priority NDA function to the cruise assist function. This can be switching NDA to ACC or NDA to ICA. The specific switch is determined by the user and is not limited here.

[0037] If the cruise assist function is active, the cruise assist function shall remain active.

[0038] Once it is determined whether the cruise assist function is ACC or ICA in operation, the current cruise assist function will continue to operate.

[0039] In some embodiments of this application, when the slip ratio of all wheels is less than or equal to a second preset value, the driving assistance system maintains its existing functional activation state.

[0040] Specifically, within the T2 ms period, when the slip ratio of the left front wheel is S FL The wheel slip ratio of the right front vehicle is S FR The slip ratio of the left rear wheel is S RL and the slip ratio S of the right rear wheel RR If all values ​​are less than or equal to S2, the current active function remains active.

[0041] In this application, the slip ratio of each wheel is acquired; the activation status of the driving assistance system is acquired; if the activation status is "activated," the driving assistance function is processed according to a preset condition reached by the slip ratio of the wheels. By acquiring the slip ratio of each wheel in real time, the activation status of the driving assistance system is obtained. When the driving assistance system is activated, the acquired slip ratio of each wheel is compared with the preset condition. When the slip ratio reaches different preset conditions, the driving assistance system performs different function activation, switching, and deactivation operations based on the slip ratio, thereby improving the driver's comfort and safety during driving.

[0042] Please see Figure 4 , Figure 5 , Figure 4 A flowchart illustrating a driving assistance function processing method according to another embodiment of this application is shown.​​ Figure 5 This invention illustrates a schematic diagram of the driving assistance function state under different preset conditions when the driving assistance system is not activated, according to another embodiment of this application. The driving assistance function processing method may specifically include the following steps:

[0043] Step S210: Obtain the slip ratio of the wheel.

[0044] Step S220: Obtain the activation status of the driving assistance system.

[0045] The above steps S210 to S220 can be referred to in detail for steps S110 to S120, and will not be repeated here.

[0046] Step S230: If the activation state is inactive, when the slip ratio of at least one of the wheels is greater than the second preset value and less than or equal to the first preset value, activate other driving assistance functions besides the navigation driving assistance function, where the second preset value is less than the first preset value.

[0047] Driving assistance functions can include various features such as navigation-based driving assistance, adaptive cruise control, automatic parking, and electronic stability control. Navigation-based driving assistance allows for autonomous overtaking, lane changing, entering and exiting ramps, merging into main roads, and other maneuvers based on navigation route guidance or surrounding traffic conditions. Cruise control locks onto the vehicle ahead in the same lane; after setting a reasonable speed and distance, it can follow the vehicle ahead, accelerating or decelerating, stopping, or starting. Adaptive cruise control uses distance sensors to measure the distance and relative speed to the vehicle ahead in real time, calculates appropriate throttle or brake control, and automatically adjusts to control the vehicle's speed and distance. When there is no vehicle ahead, adaptive cruise control maintains a constant speed by controlling the engine throttle opening according to a preset speed. Automatic parking consists of a sensing unit, a central controller, a steering actuator, and a human-machine interface system. Electronic stability control is a computer technology that detects and suppresses a decrease in tire grip.

[0048] When the current slip ratio of the vehicle does not meet the activation conditions of ABS, TCS and driving assistance system, and the slip ratio of at least one of the wheels is greater than the second preset value and less than or equal to the first preset value, other driving assistance functions in the driving assistance system other than the navigation driving assistance system are activated to increase the driver's driving comfort.

[0049] Specifically, within the T1 ms period, let the first preset value be S1 and the second preset value be S2. When S2 FL ≤S1 and S2 RR ​​When the time is ≤S1, the NDA function is not activated, but other driving assistance functions are activated, such as adaptive cruise control, automatic parking, and electronic stability control.

[0050] In some embodiments of this application, the driving assistance system is activated when the activation state is inactive and the slip ratio of all wheels in the wheel is less than or equal to a second preset value.

[0051] The driver assistance system is activated when the slip ratio of all wheels is less than or equal to a second preset value. This ensures that even if the driver does not send an activation command to the driver assistance system, the vehicle's control center will automatically activate the system based on the current wheel slip ratio to improve driver comfort.

[0052] Specifically, within the T1 ms period, when the slip ratio of the left front wheel is S FL The wheel slip ratio of the right front vehicle is S FR The slip ratio of the left rear wheel is S RL and the slip ratio S of the right rear wheel RR When all values ​​are less than or equal to S2, all driving assistance functions in the driving assistance system are activated.

[0053] In other embodiments of this application, when the slip ratio of at least one of the wheels is less than a first preset value, the slip ratio does not meet the activation condition of the driving assistance system, and the driving assistance system will not be activated at this time.

[0054] Specifically, within the T1 ms period, when S1 FL And S1 RR At this time, the slip ratio does not meet the preset conditions for activating any driving assistance function, and no driving assistance function is activated.

[0055] In the above embodiments, the first preset value can be selected from 10% to 20%, preferably 15%, and the second preset value can be selected from 5% to 15%, preferably 10%. The specific values ​​of the first and second preset values ​​can be set by the user.

[0056] Please see Figure 6 ​​In the actual use of the intelligent driving assistance system, the wheel speed detection device in each wheel uses wheel speed sensors to detect the wheel speed pulses of each wheel. The vehicle's braking control module processes the wheel speed pulses detected by the wheel speed sensors to obtain the slip ratio of each wheel. When other detection devices and other function judgment signals are functioning normally, after the intelligent driving assistance system receives an activation request from the user, if the slip ratio exceeds the preset conditions, it indicates excessive friction between the vehicle's tires and the road surface, but the ABS and TCS activation conditions have not been met. To ensure normal vehicle operation, the intelligent driving assistance system disengages at this time, and the steering wheel vibrates, while an audible alarm sounds, reminding the user to take over driving. The system status display device constantly shows whether the intelligent driving assistance system's functions are available and its activation status, allowing users to monitor the system's status in real time.

[0057] In this application, the slip ratio is determined based on the active and inactive states of the driving assistance system, thereby determining whether multiple driving assistance functions are activated or switched. This not only ensures the safety of vehicle driving but also further improves the comfort of intelligent driving even when ABS and TCS are not activated.

[0059] In some embodiments of this application, the processing module 330 includes an exit module, used to exit the driving assistance system when the slip ratio of at least one of the wheels is greater than a first preset value.

[0068] The availability (when the intelligent driving assistance system is not activated) or degraded strategy, and whether to disengage (when the intelligent driving assistance system is activated), are determined based on the slip ratio of each wheel. The steering wheel uses vibration (vibration intensity, frequency, and duration are all TBD) and an audible alarm device uses an alarm tone (decibels, timbre, and duration are all TBD) to alert the driver to take over the vehicle and that the intelligent driving assistance system is about to disengage. The system status display device informs the driver of the intelligent driving assistance system's operating status through the driver interface.
