[0023] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0024] This application embodiment provides a driving mode prompt method, please refer to Figure 1 , which shows a schematic diagram of the implementation environment of the method provided in the embodiment of the present application. The implementation environment may include: ECU (Electronic Control Unit) 11, vehicle navigation device 12, video recognition device 13, camera 14, rain and snow detection device 15, wheel speed sensor 16, torque sensor 17, radar 18, large screen 19 of the center console, audio 110, power output system 111, brake system 112 and steering system 113.

[0025] In a possible implementation, ECU11 obtains the slope of the first distance ahead of the road where the vehicle is located and the weather conditions of the road where the vehicle is located for a certain period of time in the future through the on-board navigation device 12. The road surface at the first distance ahead of the road where the vehicle is located is photographed by the camera 14 on the vehicle, and then the photographed video is recognized by the video recognition device 13 to obtain the road surface flatness at the first distance ahead of the road where the vehicle is located. ECU11 obtains the rain and snow detection result of the current position of the road where the vehicle is located through the rain and snow amount detection device 15 installed on the wiper. The wheel speed of the vehicle is detected by the wheel speed sensor 16, the driving speed of the vehicle is calculated based on the wheel speed, and then the slip rate of the vehicle is calculated based on the driving speed and wheel speed of the vehicle. The current torque of the vehicle is detected by the torque sensor 17.

[0026] Exemplarily, in response to the slope being greater than a slope threshold, ECU11 selects the uphill mode as the recommended driving mode; in response to the road surface flatness being less than a flatness threshold and the driving speed being greater than a speed threshold, ECU11 selects the off-road mode as the recommended driving mode; in response to the rain and snow detection result indicating that the weather at the current location of the vehicle on the road is not rainy or snowy and the weather state in a certain period of time in the future will be rainy or snowy, or the slip rate of the wheel is greater than at least one of the slip rate thresholds, ECU11 selects the anti-skid mode as the recommended driving mode; in response to the driving speed being greater than a speed threshold and the torque being greater than a torque threshold, ECU11 selects the sports mode as the recommended driving mode.

[0027] Optionally, after completing the selection of the recommended driving mode, in response to the current driving mode of the vehicle being inconsistent with the recommended driving mode, the ECU 11 obtains the buffer distance between the current position of the vehicle and the road section corresponding to the recommended driving mode through the vehicle navigation device 12. If the buffer distance is greater than the distance threshold, the first prompt message is displayed on the large screen 19 of the vehicle center console, prompting the driver to switch to the recommended driving mode in advance; if the buffer distance is less than or equal to the distance threshold, a voice announcement is made through the vehicle's audio 110, prompting the driver to switch to the recommended driving mode in advance.

[0028] For example, the ECU 11 detects whether there is an obstacle within the third distance ahead of the vehicle on the road through the radar 18. If there is an obstacle within the third distance ahead of the vehicle on the road, the ECU 11 can display a second prompt message through the large screen 19 of the vehicle center console to remind the driver to avoid the obstacle ahead; or can make a voice announcement through the vehicle's audio 110 to remind the driver to avoid the obstacle ahead. After sending the second prompt message, the ECU 11 shoots the obstacle through the camera 14 on the vehicle, and then identifies the shot video through the video recognition device 13 to determine the type of obstacle.

[0029] In one possible implementation, if the distance between the vehicle and the obstacle is less than the fourth distance, and the type of obstacle is a pedestrian or other vehicle, ECU11 sends a deceleration and avoidance instruction to the vehicle's power output system 111, braking system 112 and steering system 113, and controls the vehicle's power output system 111, braking system 112 and steering system 113 to make adjustments based on the instructions sent by ECU11, slowing down the vehicle's driving speed or adjusting the vehicle's driving path, thereby avoiding collision with the obstacle or reducing the risk of collision with the obstacle.

[0030] Among them, ECU 11, vehicle navigation device 12, video recognition device 13, camera 14, rain and snow detection device 15, wheel speed sensor 16, torque sensor 17, radar 18, large screen of the center console 19, audio 110, power output system 111, brake system 112 and steering system 113 establish communication connection through wired or wireless network.

[0031] Based on the above Figure 1 In the implementation environment shown in FIG. 1 , the present application embodiment provides a driving mode prompting method such as Figure 2 As shown, taking the method applied to ECU as an example, the method includes steps 201 to 204.

[0032] In step 201, the ECU obtains first road condition information of a first distance ahead of the road where the vehicle is located and second road condition information of the current position of the road where the vehicle is located.

[0033] For example, the first road condition information includes the slope of a first distance ahead of the road where the vehicle is located, the road surface flatness and the weather conditions for a certain period of time in the future, wherein the first distance can be set based on experience. Next, examples are given for the acquisition methods of each first road condition information.

[0034] (1) Obtain the slope of the first distance ahead of the vehicle

[0035] Optionally, obtaining the slope of a first distance ahead of the road where the vehicle is located includes: the ECU obtaining the slope of a first distance ahead of the road where the vehicle is located through an on-board navigation device.

[0036] (2) Obtain the weather conditions of the road where the vehicle is located for a certain period of time in the future

[0037] Exemplarily, obtaining the weather conditions of the road where the vehicle is located at a certain time in the future includes: the ECU obtains the weather conditions of the road where the vehicle is located at a certain time in the future through the on-board navigation device, wherein the first weather condition includes but is not limited to: sunny, cloudy, foggy, rainy and snowy, and cloudy, and the duration of the certain time in the future can be determined based on the duration of the vehicle traveling through the first distance.

[0038] (3) Obtain the road surface smoothness at the first distance ahead of the vehicle

[0039] In one possible implementation, obtaining the road surface roughness at a first distance ahead of the vehicle includes: the ECU photographs the road surface at a first distance ahead of the vehicle through a camera on the vehicle, and then recognizes the photographed video through a video recognition device to obtain the road surface roughness at a first distance ahead of the vehicle.

[0040] Exemplarily, the second road condition information includes a rain and snow detection result at the current position of the road where the vehicle is located, and the rain and snow detection result at the current position of the road where the vehicle is located is used to indicate whether the weather at the current position of the road where the vehicle is located is rainy and snowy. Obtaining the rain and snow detection result at the current position of the road where the vehicle is located includes: the ECU detects whether there is rain or snow on the current wiper through a rain and snow amount detection device installed on the wiper. In response to the presence of at least one of rain or snow on the current wiper, the rain and snow detection result at the current position of the road where the vehicle is located indicates that the weather at the current position of the road where the vehicle is located is rainy and snowy; in response to the absence of rain and snow on the current wiper, the rain and snow detection result at the current position of the road where the vehicle is located indicates that the weather at the current position of the road where the vehicle is located is not rainy and snowy.

[0041] In step 202, the ECU obtains the current operating condition information of the vehicle.

[0042] Exemplarily, the current working condition information of the vehicle includes the vehicle's driving speed, torque and wheel speed. Next, examples are given for the acquisition of each working condition information.

[0043] (1) Get the current wheel speed of the vehicle

[0044] Optionally, obtaining the current wheel speed of the vehicle includes: the ECU can detect the wheel speed of the vehicle through a wheel speed sensor, wherein the wheel speed sensor is installed on the drive shaft or steering knuckle of the driving wheel of the vehicle to monitor the wheel speed of the vehicle.

[0045] (2) Obtain the current torque of the vehicle

[0046] In a possible implementation, the current torque of the vehicle is obtained, including: the ECU can detect the current torque of the vehicle through a torque sensor, wherein the torque sensor is installed on the power output system to monitor the torque of the power output system.

[0047] (3) Obtain the vehicle's current speed

[0048] Exemplarily, after determining the current wheel speed of the vehicle, the current driving speed of the vehicle is obtained, including: the ECU calculates the current driving speed of the vehicle based on the current wheel speed of the vehicle, wherein the correspondence between the wheel speed and the driving speed of the vehicle can be determined in advance through experiments.

[0049] In step 203 , based on the first road condition information, the second road condition information and the operating condition information, the ECU selects a recommended driving mode.

[0050] Optionally, after determining the first road condition information, the second road condition information and the operating condition information, the ECU selects a recommended driving mode, including: in response to the slope being greater than a slope threshold, selecting an uphill mode as the recommended driving mode; in response to the road surface flatness being less than a flatness threshold and the driving speed being greater than a speed threshold, selecting an off-road mode as the recommended driving mode; calculating the slip rate of the wheel based on the driving speed and the wheel speed; in response to the rain and snow detection result indicating that the weather at the current location of the vehicle on the road is not rainy or snowy and the weather state for a certain period of time in the future will be rainy or snowy, or the slip rate of the wheel is greater than at least one of the slip rate thresholds, selecting an anti-skid mode as the recommended driving mode; in response to the driving speed being greater than a speed threshold and the torque being greater than a torque threshold, selecting a sports mode as the recommended driving mode.

[0051] Exemplarily, during the driving process of the vehicle, the slope of the first distance ahead of the road where the vehicle is located is continuously monitored, and the slope of the first distance ahead of the road where the vehicle is located is compared with the slope threshold value. If the slope of the first distance ahead of the road where the vehicle is located is greater than the slope threshold value, the ECU selects the uphill mode as the recommended driving mode. Optionally, during the driving process of the vehicle, the road surface flatness of the first distance ahead of the road where the vehicle is located is continuously monitored, and the road surface flatness of the first distance ahead of the road where the vehicle is located is compared with the flatness threshold value, and the current driving speed of the vehicle is compared with the speed threshold value. If the road surface flatness is less than the flatness threshold value and the driving speed is greater than the speed threshold value, the ECU selects the off-road mode as the recommended driving mode.

[0052] In a possible implementation, the vehicle's driving speed, the vehicle's wheel speed, the rain and snow detection result of the current position of the vehicle's road, and the weather conditions of the vehicle's road in the future are continuously monitored during the vehicle's driving process, and the current wheel slip rate of the vehicle is calculated based on the vehicle's current driving speed and the vehicle's current wheel speed. Exemplarily, the formula for calculating the wheel slip rate based on the driving speed and wheel speed is as follows:

[0053] S=(VW)÷V

[0054] For example, S is the slip rate of the wheel, V is the driving speed of the vehicle, and W is the wheel speed of the vehicle. V and W need to be converted into corresponding units before calculation.

[0055] In a possible implementation, after the calculation of the vehicle's slip rate is completed, the slip rate of the current wheel of the vehicle is compared with the slip rate threshold. If the rain and snow detection result indicates that the weather at the current location of the vehicle is not rainy or snowy and the weather state in the future is rainy or snowy, or the slip rate of the wheel is greater than at least one of the slip rate thresholds, the ECU selects the anti-skid mode as the recommended driving mode.

[0056] Optionally, the current driving speed of the vehicle is compared with a speed threshold, and the current torque of the vehicle is compared with a torque threshold. If the driving speed is greater than the speed threshold and the torque is greater than the torque threshold, the ECU selects the sport mode as the recommended driving mode. Exemplarily, the slope threshold, the flatness threshold, the speed threshold, the slip rate threshold, the speed threshold and the torque threshold can be set based on experience.

[0057] Exemplarily, the ECU obtains the traffic flow at a second distance ahead of the road where the vehicle is located, and the second distance is less than the first distance; in response to the traffic flow being greater than the flow threshold, the economy mode is selected as the recommended driving mode. In a possible implementation, the ECU may obtain the traffic flow at a second distance ahead of the road where the vehicle is located through an onboard navigation device. Optionally, the second distance may be set based on experience, and the second distance needs to be less than the first distance.

[0058] In one possible implementation, after determining the traffic flow at a second distance ahead of the road where the vehicle is located, the traffic flow is compared with a flow threshold, and if the traffic flow is greater than the flow threshold, the ECU selects the economy mode as the recommended driving mode.

[0059] In step 204 , in response to the current driving mode of the vehicle being inconsistent with the recommended driving mode, the ECU issues a first prompt message, where the first prompt message instructs switching the driving mode of the vehicle to the recommended driving mode.

[0060] Optionally, after completing the selection of the recommended driving mode, in response to the vehicle's current driving mode being inconsistent with the recommended driving mode, a buffer distance of the vehicle from the road section corresponding to the recommended driving mode is obtained; in response to the buffer distance being greater than a distance threshold, a first prompt message is issued in text form; in response to the buffer distance being less than or equal to the distance threshold, a first prompt message is issued in voice form.

[0061] Exemplarily, after the recommended driving mode is selected, the recommended driving mode is compared with the current driving mode of the vehicle. If the current driving mode of the vehicle is inconsistent with the recommended driving mode, a buffer distance of the vehicle from the road section corresponding to the recommended driving mode is obtained, including: the ECU obtains the buffer distance between the current position of the vehicle and the road section corresponding to the recommended driving mode through the on-board navigation device.

[0062] In a possible implementation, the buffer distance is compared with a distance threshold. If the buffer distance is greater than the distance threshold, a first prompt message is sent in text form, for example, the first prompt message can be displayed on a large screen of the vehicle center console, prompting the driver to switch to the recommended driving mode in advance; if the buffer distance is less than or equal to the distance threshold, the first prompt message is sent in voice form, for example, the voice can be broadcasted through the vehicle's audio, prompting the driver to switch to the recommended driving mode in advance. Optionally, the distance threshold can be set based on experience.

[0063] Exemplarily, during the driving of the vehicle, a radar detection result is obtained, wherein the radar detection result is used to indicate whether there is an obstacle within a third distance in front of the road where the vehicle is located. In response to the radar detection result indicating that there is an obstacle within the third distance in front of the road where the vehicle is located, a second prompt message is issued, and the second prompt message indicates to pay attention to avoid the obstacle in front. Optionally, the radar can be installed in front of the vehicle.

[0064] In a possible implementation, if the radar detects that there is an obstacle within the third distance ahead of the vehicle on the road, the radar detection result indicates that there is an obstacle within the third distance ahead of the vehicle on the road; if the radar does not detect that there is an obstacle on the vehicle's road or the obstacle detected by the radar is outside the third distance ahead of the vehicle on the road, the radar detection result indicates that there is no obstacle within the third distance ahead of the vehicle on the road. The third distance can be set based on experience and needs to be smaller than the farthest detection distance of the radar.

[0065] Optionally, after determining the radar detection result, if the radar detection result indicates that there is an obstacle within a third distance ahead of the road where the vehicle is located, the ECU issues a second prompt message, wherein the second prompt message instructs the driver to pay attention to avoid the obstacle ahead. Exemplarily, the ECU issues the second prompt message, including: the ECU may display the second prompt message on a large screen on the vehicle's center console, prompting the driver to pay attention to avoid the obstacle ahead; and may make a voice announcement through the vehicle's speakers, prompting the driver to pay attention to avoid the obstacle ahead.

[0066] In one possible implementation, after issuing the second prompt message, the ECU identifies the type of obstacle, where the types of obstacles include pedestrians, objects, and other vehicles; in response to the distance between the vehicle and the obstacle being less than a fourth distance and the type of obstacle being a pedestrian or other vehicles, the vehicle is controlled to slow down and avoid the obstacle.

[0067] For example, the ECU takes a photo of the obstacle through a camera on the vehicle, and then uses a video recognition device to recognize the taken video to determine the type of the obstacle. After determining the type of the obstacle, the distance between the vehicle and the obstacle is compared with the fourth distance. If the distance between the vehicle and the obstacle is less than the fourth distance, and the type of the obstacle is a pedestrian or other vehicle, the ECU controls the vehicle to slow down and avoid it.

[0068] Optionally, the ECU controls the vehicle to decelerate and avoid, including: the ECU sends a deceleration and avoidance instruction to the vehicle's power output system, brake system, and steering system, such as increasing the braking force, adjusting the throttle, or changing the driving direction. After receiving the instruction from the ECU, the vehicle's power output system, brake system, and steering system are adjusted based on the ECU instruction to slow down the vehicle's driving speed or adjust the vehicle's driving path, thereby avoiding collision with obstacles or reducing the risk of collision with obstacles.

[0069] In summary, Figure 3 The prompt logic flow chart of the driving mode shown is used as an example for illustration. Among them, the execution subject can be ECU. Step 301, obtain the slope of the first distance ahead of the road where the vehicle is located and the weather conditions of the road where the vehicle is located for a certain period of time in the future through the on-board navigation device. Step 302, use the camera on the vehicle to shoot the road surface at the first distance ahead of the road where the vehicle is located, and then use the video recognition device to recognize the shot video to obtain the flatness of the road surface at the first distance ahead of the road where the vehicle is located. Step 303, ECU obtains the rain and snow detection result of the current position of the road where the vehicle is located through the rain and snow amount detection device installed on the wiper.

[0070] In a possible implementation, in step 304, the wheel speed of the vehicle is detected by a wheel speed sensor, the driving speed of the vehicle is calculated based on the wheel speed, and the slip rate of the vehicle is calculated based on the driving speed and the wheel speed. In step 305, the current torque of the vehicle is detected by a torque sensor. In step 306, the parameter conditions preset for each driving mode are obtained. In step 307, the target recommended driving mode is selected. In step 308, it is determined whether the current driving mode of the vehicle is consistent with the recommended target driving mode. If the current driving mode of the vehicle is consistent with the recommended target driving mode, the process proceeds to step 309; if the current driving mode of the vehicle is inconsistent with the recommended target driving mode, the process proceeds to step 310. In step 309, the vehicle is controlled to keep the current driving mode unchanged. In step 310, a first prompt message is issued.

[0071] The embodiment of the present application monitors and analyzes road condition information and vehicle status in real time by acquiring first road condition information at a first distance ahead of the vehicle on the road, second road condition information at the current position of the vehicle on the road, and current operating condition information of the vehicle; selects a recommended driving mode for the vehicle based on the first road condition information, the second road condition information, and the current operating condition information of the vehicle to ensure the comprehensiveness and accuracy of the selected recommended driving mode; and sends a first prompt message to prompt the driver to switch the vehicle to the recommended driving mode when the current driving mode of the vehicle is inconsistent with the recommended driving mode, thereby achieving early selection of the driving mode and prompting the driver to ensure the accuracy and timeliness of the driving mode switching, thereby improving driving safety and comfort.
