[0027] As mentioned above, with the increasing popularity of automobiles, the road conditions on which vehicles are driving are becoming increasingly complex. Drivers need to pay attention to the road conditions ahead and brake in time to control the speed and distance of the vehicle. With the continuous advancement of automotive electronic technology, brake prompt technology can be developed and adapted to vehicles with the current level of intelligence, thereby enhancing the driver's ability to identify road conditions during driving and avoiding traffic accidents. At present, image sensors or ranging sensors are used to judge the risk of vehicle collision or monitor driving traffic signs to provide brake prompts in the form of icons, text or sound. However, the existing brake prompts are triggered when a single control condition is met, the information prompts are abrupt, the prompts have limited effect, and the information displayed and expressed is relatively small, which cannot meet the actual needs of brake prompts.

[0028] The embodiment of the present application provides a braking prompt method, which obtains driving state information and environmental information of the vehicle during driving when the vehicle is driving, and determines the risk level of the vehicle during driving based on the driving state information and environmental information, so as to continuously display braking prompts through risk levels to prompt the driver to brake the vehicle. Compared with the braking prompt that is immediately triggered when a single control condition is met in the prior art, the driver can be prompted to brake the vehicle in a less abrupt and more natural way. In addition, determining the risk level of the vehicle during driving can indicate the probability of a collision during driving, which is convenient for the driver to take corresponding braking measures according to the braking prompt and reduce the occurrence of traffic accidents.

[0029] The braking prompt method provided by the present application is described below by way of an embodiment.

[0030] Figure 1 is a flow chart of a braking prompt method provided in an embodiment of the present application, such as Figure 1As shown, the braking prompt method includes the following steps 101 to 103:

[0031] Step 101: Acquire driving state information of a vehicle during driving, and acquire environmental information.

[0032] During the driving process of the vehicle, the driving status information of the vehicle is collected in real time. The driving status information can indicate the driving status of the vehicle, such as: the vehicle's driving lane, speed, etc. In one example, the vehicle's driving status information can be collected by sensors and sent to the vehicle's instrument system through the CAN bus.

[0033] While collecting the driving status information of the vehicle during driving, environmental information is collected in real time. The environmental information can indicate the current driving environment of the vehicle. For example, the current weather conditions can be obtained. Different weather will have different impacts on the driving process. For example, on rainy and snowy days, the braking distance of the vehicle is longer than on sunny days.

[0034] Step 102: Determine the risk level of the vehicle during driving according to the driving state information and the environmental information.

[0035] The risk level of the vehicle during driving is determined based on the collected driving state information and environmental information. The risk level of the vehicle during driving can indicate the risk of collision of the vehicle, for example, the risk of collision between the vehicle and the vehicle in front or with an obstacle. In one example, the risk level can indicate the probability of collision. The risk level can be divided into multiple levels. The higher the risk level, the higher the probability of collision.

[0036] Step 103: Continuously display a braking reminder according to the risk level.

[0037] According to the risk level of the vehicle during driving, the braking prompt is continuously displayed, and the braking prompt can remind the driver to brake. In one example, the braking prompt can be continuously displayed in the field of vision of the main driver to make the main driver notice the braking prompt.

[0038] In an embodiment of the present application, when the vehicle is driving, the driving state information and environmental information of the vehicle during driving are obtained, and the risk level of the vehicle during driving is determined based on the driving state information and environmental information, so as to continuously display a braking prompt through the risk level to prompt the driver to brake the vehicle. Compared with the braking prompt that is immediately triggered when a single control condition is met in the prior art, the driver can be prompted to brake the vehicle in a less abrupt and more natural way. In addition, determining the risk level of the vehicle during driving can indicate the probability of a collision during driving, making it convenient for the driver to take corresponding braking measures according to the braking prompt and reduce the occurrence of traffic accidents.

[0039] In one possible implementation, when obtaining driving status information of a vehicle and obtaining environmental information during driving, the vehicle speed during driving can be obtained, the distance between the vehicle and an obstacle during driving can be obtained, wherein the obstacle is located in the driving direction of the vehicle, and the light intensity and air humidity during driving of the vehicle can be obtained.

[0040] The vehicle speed and the distance to obstacles are collected during the driving process of the vehicle. In one example, the current vehicle speed can be detected by the vehicle speed sensor, and the distance between the vehicle and obstacles can be detected by the vehicle camera and radar. The obstacles can be obstacles in front of the vehicle in the driving direction, including but not limited to vehicles in front of the vehicle in the driving direction, traffic signs, road depressions and pedestrians. After the vehicle speed and the distance to obstacles are collected by the sensor, the collected data is sent to the vehicle's instrument system through the CAN bus.

[0041] The vehicle's environmental information is collected during driving. In one example, the light intensity of the external environment can be collected through a light sensor, and the temperature of the external environment can be collected through a temperature sensor. After the light intensity and air humidity during vehicle driving are collected, the collected data is sent to the vehicle's instrument system through the CAN bus.

[0042] In the embodiment of the present application, the vehicle speed, the distance to obstacles, the light intensity and the air humidity during the driving process are collected, so that the vehicle can obtain the driving status information and environmental information of the vehicle in real time through the CAN bus during the driving process, and realize the acquisition of real-time road condition information, so as to provide corresponding braking prompts for different road conditions during the driving process of the vehicle, which is convenient for the driver to take corresponding braking measures according to the braking prompts, and can reduce the occurrence of traffic accidents.

[0043] In one possible implementation, when determining the risk level of a vehicle during driving based on driving status information and environmental information, a sensitivity coefficient can be determined based on the environmental information, a braking risk value can be determined based on the driving status information, the sensitivity coefficient and the mass of the vehicle, and the risk level can be determined based on the braking risk value.

[0044] According to the obtained light intensity and air humidity of the vehicle during driving, the sensitivity coefficient is determined, and the braking risk value is calculated in combination with the obtained vehicle speed, the distance between the vehicle and the obstacle, and the mass of the vehicle during driving. In one example, the braking risk value can be calculated by the objective function P(t)=F[v(t),d(t),M]*K, where v(t) is used to characterize the vehicle speed, d(t) is used to characterize the distance between the vehicle and the obstacle, M is used to characterize the mass of the vehicle, and K is used to characterize the sensitivity coefficient. According to the calculated braking risk value, the risk level is determined. Specifically, the risk level can be divided into multiple levels, each risk level corresponds to a numerical interval. If the calculated braking risk value is within a certain numerical interval, it is determined that the risk level of the vehicle during driving at this time is the risk level corresponding to the numerical interval.

[0045] In an embodiment of the present application, a sensitivity coefficient is determined based on environmental information, a braking risk value is calculated based on driving status information, the sensitivity coefficient and the mass of the vehicle, and a risk level is determined based on the braking risk value. Compared with the prior art which only identifies a single road condition to prompt a collision risk, priority is given to complex road conditions during vehicle driving, and the driver's energy consumption in identifying road conditions is reduced, thereby reducing the driver's driving fatigue and the occurrence of traffic accidents.

[0046] In a possible implementation, when determining the sensitivity coefficient according to environmental information, a first sensitivity set by a user may be obtained, a sensitivity correction coefficient may be determined according to the environmental information, and the first sensitivity may be corrected by the sensitivity correction coefficient to obtain the sensitivity coefficient.

[0047] The user can set the first sensitivity. In one example, Figure 2 is a schematic diagram of a setting interface provided in an embodiment of the present application, such as Figure 2 As shown, the setting interface 200 includes a sensitivity level setting area 201, which displays multiple sensitivity levels and supports the user to select one of the multiple sensitivity levels. In one example, the sensitivity level can be represented by numbers, such as 1, 2, 3...; in another example, for example Figure 2 As shown in , the sensitivity level can also be expressed by words to indicate different sensitivity levels, such as high, medium and low. Figure 2This is only an example of sensitivity setting, and should not limit the sensitivity setting process. Specifically, in the sensitivity setting process, the sensitivity can be set by a physical button, or the sensitivity can be adjusted steplessly by dragging a setting bar, etc. The sensitivity can indicate the sensitivity of the braking prompt for the same driving state information. For example, when the sensitivity is high, the risk level determined for the same driving state information is greater than the risk level determined when the sensitivity is medium or low.

[0048] Get the first sensitivity set by the user in the instrument interface. Determine the sensitivity correction coefficient based on the environmental information obtained. It should be understood that when the ambient light intensity is high and the humidity is low, it can be determined that the current weather is sunny. When the ambient light intensity is low and the humidity is high, it can be determined that the current weather is rainy. Therefore, the weather conditions can be determined by the ambient light intensity and air humidity. Since the braking distance is different in different weather conditions, when the weather is good and conducive to vehicle driving, the sensitivity correction coefficient can reduce the first sensitivity to normally prompt the brake to adapt to a shorter braking distance. When the weather is bad and not conducive to vehicle driving, the sensitivity correction coefficient can increase the first sensitivity to prompt the brake to adapt to a longer braking distance in advance. Use the sensitivity correction coefficient to correct the first sensitivity and obtain the sensitivity coefficient to obtain the sensitivity coefficient applicable to the current driving process.

[0049] In the embodiment of the present application, the first sensitivity set by the user is obtained, and the user is supported to set the sensitivity coefficient of the brake prompt during the vehicle driving process according to personal driving experience and driving habits, thereby optimizing the driver's riding experience. And according to the environmental information, the sensitivity correction coefficient is determined, and the first sensitivity is corrected to obtain the sensitivity coefficient suitable for the current driving process, so as to achieve the addition of the environmental optimization strategy based on the sensitivity set by the user, and the sensitivity of the brake prompt can be dynamically adjusted according to the environmental information during the vehicle driving process, so that the sensitivity coefficient is suitable for the current driving environment, and the driver is assisted in identifying different environmental road conditions, which can reduce the occurrence of traffic accidents.

[0050] In one possible implementation, when the braking prompt is continuously displayed according to the risk level, a braking prompt display strategy can be determined according to the risk level, and according to the braking prompt display strategy, the braking prompt is continuously displayed on at least one of the vehicle's windshield, the vehicle's central control screen, and the vehicle's instrument area.

[0051] A braking prompt display strategy is determined based on the risk level. The braking prompt display strategy can indicate how to display the braking prompt. According to the braking prompt display strategy, the braking prompt is displayed within the driver's field of view, that is, the braking prompt is continuously displayed on at least one of the vehicle's windshield, the vehicle's central control screen, and the vehicle's instrument area. In one example, after the user activates the vehicle's head-up display function, or by changing the partial front windshield translucent display, the braking prompt is continuously displayed on the vehicle's windshield. If the user does not activate the vehicle's head-up display function, the braking prompt may be continuously displayed on the vehicle's central control screen and / or the vehicle's instrument area. Optionally, the user can set the display area of ​​the braking prompt by himself.

[0052] In an embodiment of the present application, a braking prompt display strategy is determined based on the risk level. Based on the braking prompt display strategy, the braking prompt is continuously displayed on at least one of the vehicle's windshield, the vehicle's central control screen, and the vehicle's instrument area. Thus, the braking prompt can be continuously displayed in the driver's field of vision, which can prevent the braking prompt from being abrupt, allowing the driver to continue to pay attention to the braking prompt, reducing the driver's energy consumption in identifying road conditions, and reducing the occurrence of traffic accidents.

[0053] In one possible implementation, when determining the braking prompt display strategy based on the risk level, if the risk level is greater than or equal to the level threshold, the braking prompt is displayed in a first color; if the risk level is less than the level threshold, the braking prompt is displayed in a second color, wherein the first color is different from the second color.

[0054] The level threshold can be set as needed. If the risk level is greater than or equal to the level threshold, the braking prompt display strategy is to display the braking prompt in the first color. If the risk level is less than the level threshold, the braking prompt display strategy is to display the braking prompt in the second color. For example: the risk level is divided into five levels 1-5, and the level threshold can be set to level 4. When the risk level is level 4 and level 5, the braking prompt display strategy is to display the braking prompt in dark red. When the risk level is level 1-3, the braking prompt display strategy is to display the braking prompt in dark green.

[0055] In the embodiment of the present application, if the risk level is greater than or equal to the level threshold, the braking prompt is displayed in a first color, and if the risk level is less than the level threshold, the braking prompt is displayed in a second color, wherein the first color is different from the second color. Users can be supported to set different braking prompt display colors according to their preferences, and the color changes reflect the urgency of the need to take braking measures, which can more clearly and intuitively reflect the risk of collision to the driver, thereby reducing the occurrence of traffic accidents.

[0056] In a possible implementation, when determining the braking prompt display strategy according to the risk level, the filling degree of the braking prompt in the container-shaped display may be determined according to the risk level, wherein the filling degree is proportional to the risk level.

[0057] Figure 3 is a schematic diagram of a brake prompt display interface provided in an embodiment of the present application, such as Figure 3 As shown, the braking prompt display interface 300 includes a braking prompt display area 301. Different risk levels correspond to different degrees of filling of the braking prompt in the container-shaped display. The degree of filling includes but is not limited to being expressed by length, content, and saturation. The degree of filling of the braking prompt in the container-shaped display is proportional to the risk level. In one example, Figure 3 As shown, the braking reminder display area 301 displays the braking reminder in the form of a rectangular bar. According to the risk level, the display length of the rectangular bar is dynamically adjusted, and the display length is proportional to the risk level. For example, when the risk level is low, the rectangular bar is filled with a shorter length and a lower degree of filling (for example Figure 3 When the risk level is high, the rectangular bar is filled with a longer length and a higher degree of filling (e.g. Figure 3 In one example, the braking reminder display area can display the braking reminder in the form of a circular container. According to the risk level, the filling degree of the circular container is dynamically adjusted, and the filling degree of the filling content is proportional to the risk level. In one example, the braking reminder display interface can be the windshield of the vehicle, by projecting it onto the driver's front windshield head-up display, or partially changing the front windshield light transmission display. In one example, the braking reminder display interface can be the instrument screen and / or the central control screen. It should be noted that Figure 3 This is just an example, and the specific display situation can be set as needed. For example, the container shape of the container-shaped display can be set as needed, and the display effects of different filling levels can also be set as needed, which is not limited here.

[0058] It should be noted that when determining the braking prompt display strategy, the display color of the braking prompt can be determined according to the risk level while determining the degree of fullness of the braking prompt in the container-shaped display according to the risk level, that is, different colors are used to display different degrees of fullness of the braking prompt in the container-shaped display. For example: when the risk level is high, it is displayed by a longer dark red rectangular bar, and when the risk level is low, it is displayed by a shorter dark green rectangular bar.

[0059] In an embodiment of the present application, according to the risk level, the degree of filling of the braking prompt in the container-shaped display is determined to be proportional to the risk level. The change in the degree of filling of the braking prompt in the container-shaped display is used to reflect the urgency of the need to take braking measures, and the risk of collision is reflected to the driver more clearly and intuitively, thereby enhancing the driver's ability to predict risks for different road conditions during driving, thereby reducing the occurrence of traffic accidents.

[0060] In a possible implementation, when determining the braking prompt display strategy according to the risk level, at least one of the display brightness, color saturation, color appearance and contrast of the braking prompt may be determined according to the risk level.

[0061] Different risk level intervals may correspond to different braking prompt display effects. When the risk level is in a certain level interval, the corresponding braking prompt display effect is displayed. The braking prompt display effects corresponding to different level intervals may be distinguished by at least one of display brightness, color saturation, color appearance, and contrast. For example: the risk level is divided into three levels, 1-3. When the risk level is level 1, the braking prompt display strategy is to display the braking prompt at low brightness. When the risk level is level 2, the braking prompt display strategy is to display the braking prompt at medium brightness. When the risk level is level 3, the braking prompt display strategy is to display the braking prompt at high brightness.

[0062] It should be noted that when determining the braking prompt display strategy, while determining at least one of the display brightness, color saturation, color appearance and contrast of the braking prompt according to the risk level, the display color of the braking prompt and the degree of fullness in the container-like display can be determined according to the risk level, that is, different display effects of the braking prompt are displayed by different colors and different fullness levels. For example: when the risk level is high, it is displayed by a high-brightness red longer rectangular bar, and when the risk level is low, it is displayed by a low-brightness green shorter rectangular bar.

[0063] In an embodiment of the present application, at least one of the display brightness, color saturation, color appearance and contrast of the braking prompt is determined according to the risk level, which can support users to set different braking prompt display effects according to their preferences. The changes in the braking prompt effect can reflect the urgency of the need to take braking measures, and the risk of collision can be reflected to the driver more clearly and intuitively, which can reduce the occurrence of traffic accidents.

[0064] Figure 4 is a schematic diagram of a brake prompt device provided in an embodiment of the present application, such as Figure 4 As shown, the device 400 includes:

[0065] The acquisition unit 401 is used to acquire the driving state information of the vehicle during driving and acquire the environmental information;

[0066] A confirmation unit 402, used to determine the risk level of the vehicle during driving according to the driving state information and the environment information, wherein the risk level is used to indicate the risk of collision;

[0067] The display unit 403 is used to continuously display the braking prompt according to the risk level.

[0068] In the embodiment of the present application, the acquisition unit 401 can be used to execute step 101 in the above method embodiment, the confirmation unit 402 can be used to execute step 102 in the above method embodiment, and the display unit 403 can be used to execute step 103 in the above method embodiment.

[0069] In a possible implementation, the acquisition unit 401 can also acquire the vehicle speed during driving, the distance between the vehicle and an obstacle during driving, wherein the obstacle is located in the driving direction of the vehicle, and the light intensity and air humidity during driving of the vehicle.

[0070] In a possible implementation, the confirmation unit 402 may also determine a sensitivity coefficient based on environmental information, determine a braking risk value based on driving state information, the sensitivity coefficient and the mass of the vehicle, and determine a risk level based on the braking risk value.

[0071] In a possible implementation, the confirmation unit 402 may also obtain a first sensitivity set by a user, determine a sensitivity correction coefficient according to environmental information, and correct the first sensitivity by the sensitivity correction coefficient to obtain a sensitivity coefficient.

[0072] In one possible implementation, the display unit 403 can also determine a braking prompt display strategy based on the risk level, and continuously display the braking prompt on at least one of the vehicle's windshield, the vehicle's central control screen, and the vehicle's instrument area according to the braking prompt display strategy.

[0073] In one possible implementation, the display unit 403 may further display a braking prompt in a first color if the risk level is greater than or equal to a level threshold, and display a braking prompt in a second color if the risk level is less than the level threshold, wherein the first color is different from the second color.

[0074] In a possible implementation, the display unit 403 may also determine the filling degree of the braking prompt in the container-shaped display according to the risk level, wherein the filling degree is proportional to the risk level.

[0075] In a possible implementation, the display unit 403 may also determine at least one of display brightness, color saturation, color appearance, and contrast of the braking prompt according to the risk level.
