[0031] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0032] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be understood by people with ordinary skills in the field to which the present application belongs. "Include" or "comprising" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0033] With the development of the vehicle industry, vehicles are increasingly involved in our daily lives and work. When driving, users cannot predict in advance whether the road ahead will skid. Although the Electronic Stability Program (ESP) function intervenes after the vehicle skids to improve the safety and controllability of the vehicle, the sudden skidding can easily scare the user, affecting the user experience and posing a safety hazard. Therefore, there is an urgent need for a method that can provide early warning of vehicle skidding.

[0034] When existing vehicles skid, only the ESP function is triggered to keep the vehicle stable, but there is no warning or reminder function. In addition, in some extreme weather conditions, such as heavy rain, users cannot predict in advance whether there is water ahead of the driving route, and cannot judge whether the water depth allows smooth passage, as well as how to deal with engine stalling after wading. Although some on-board maps already have information on flooded sections, there is no real-time warning combined with the weather, nor is there any monitoring of the water depth, or operational guidance or rescue services for engine stalling after wading.

[0035] Below, through specific embodiments and combined Figures 1 to 5 To describe the technical solution of this application in detail.

[0036] Some embodiments of the present application provide a vehicle warning method, such as Figure 1 As shown, the following steps are included:

[0037] S1. Obtaining the current navigation route of the vehicle.

[0038] The vehicle host can obtain the current navigation route of the map module. The current navigation route can be the full navigation route in front of the vehicle, or it can be a partial navigation route in front of the vehicle, such as a 10km long navigation route in front of the vehicle, without specific limitation.

[0039] S2. When there is a sideslip section in the current navigation route, current weather information of the sideslip section is obtained, wherein the sideslip section is a section where the vehicle has previously sideslipped.

[0040] The side-slipping road section is a road section that has been stored locally or in the cloud. The side-slipping road section represents that the vehicle or other vehicles have experienced side-slipping on the road section. According to the conventional matching algorithm, it can be determined whether there is a side-slipping road section in the current navigation route. When there is a side-slipping road section, it means that the vehicle may experience side-slipping when driving on the side-slipping road section. At this time, the current weather information of the road section can be obtained in real time through the communication module for subsequent judgment. The current weather information can be a simple weather category, such as rainy, sunny, cloudy, foggy, snowy, sandstorm, etc., or more complex specific weather conditions, such as precipitation, visibility, etc.

[0041] S3. When the current weather information meets the sideslip weather information, a sideslip warning message is issued, wherein the sideslip weather information is the weather information when the vehicle has previously sideslipped on the sideslip road section.

[0042] The skidding weather information is information stored locally or in the cloud, and is the weather information when the vehicle or other vehicles skidded on the skidding road section. The skidding weather information can be a simple weather category, such as rainy days, foggy days, snowy days, sandstorm days, etc., or a more complex specific weather condition, such as precipitation, visibility, etc.

[0043] Determine whether the current weather information is consistent with the sideslip weather information. For example, when the sideslip weather information is a weather category, then it can be determined whether the current weather category is the same as the sideslip weather category. If they are the same, it means that the sideslip section is very likely to slide at this time, and a sideslip warning message can be issued for reminder. For another example, when the sideslip weather information is precipitation, then it can be determined whether the current precipitation and the sideslip precipitation are different. If the current precipitation is greater than or equal to the sideslip precipitation, it means that the sideslip section is very likely to slide at this time, and a sideslip warning message can be issued for reminder. The weather influences of sideslip mainly include rainy days, snowy days, foggy days, sandstorms, freezing rain, etc., and the weather information can be adjusted according to specific needs. The sideslip warning message is, for example, a reminder message to remind the user that the current navigation route will slide, or a reminder to reduce the speed of the vehicle, etc., without specific limitation.

[0044] This method is more accurate in judging the occurrence of sideslips because it is based on the actual road section where sideslips have occurred and the weather at the time of the sideslip. By comparing with the road section and weather where sideslips have occurred, the user is reminded to respond to the sideslips in advance. After determining that there is a sideslip section where sideslips have occurred in the current navigation route, if the current weather of the section is the same as the weather when the sideslips occurred, a sideslip warning message can be issued to remind the user to avoid scaring the user, thereby improving the user experience. The user can also prepare response strategies in advance to improve safety.

[0045] The vehicle early warning method is simple and convenient, can give early warning of side slip situations, has high safety and good user experience.

[0046] In some embodiments, step S1 includes:

[0047] S001. When a vehicle skids, a road section where the vehicle is located is stored as a sideslip road section, and weather information when the vehicle skids on the sideslip road section is stored as sideslip weather information.

[0048] When the vehicle skids, the ESP function will be triggered. Whether the vehicle skids can be determined simply by whether the ESP function is triggered. When it is determined that the vehicle skids, the road section where the skid occurred and the weather information at that time can be stored locally or in the cloud as the skidding road section and skidding weather information, so that subsequent vehicles can judge whether to issue a skidding warning information. When this vehicle or other vehicles encounter the same road section and weather again, skidding is very likely to occur again, and the user can be reminded in time.

[0049] In some embodiments, step S1 includes:

[0050] S002. When the vehicle skids, the lane where the vehicle is located is stored as a skidding lane.

[0051] When it is determined that the vehicle has skidded, the lane where the skid occurred can also be stored locally or in the cloud as a skidding lane. In this way, when this vehicle or other vehicles subsequently drive onto the skidding section again, the vehicle can be controlled to drive to lanes other than the skidding lane to avoid skidding.

[0052] In some embodiments, the vehicle warning method further includes:

[0053] S301: When the current weather information meets the side slip weather information, the vehicle body electronic stability system is turned on.

[0054] Electronic Stability Program (ESP) is a general term for systems or programs that are designed to improve vehicle handling performance while effectively preventing the vehicle from losing control when it reaches its dynamic limit. Electronic stability program can improve the safety and handling of the vehicle. ESP includes several functions, including Electronic Brake Distribution (EBD), Anti-lock Brake System (ABS), Traction Control System (TCS), and Vehicle Dynamic Control (VDC). It helps the vehicle maintain dynamic balance by analyzing the vehicle driving status information transmitted from various sensors and then sending correction instructions to ABS, EBD, etc. ESP can keep the vehicle in optimal stability under various conditions, and the effect is more obvious in the case of oversteering or understeering.

[0055] The ESP system consists of a control unit and steering sensors, wheel sensors, sideslip sensors, lateral acceleration sensors, etc. The steering sensor is used to monitor the steering angle of the steering wheel, the wheel sensor is used to monitor the speed of each wheel, the sideslip sensor is used to monitor the state of rotation of the vehicle body around the vertical axis, and the lateral acceleration sensor is used to monitor the centrifugal force when the car turns.

[0056] Under certain road conditions and vehicle load conditions, the maximum adhesion that the wheel can provide is a fixed value, that is, under extreme conditions, the longitudinal force and lateral force on the wheel are in a trade-off relationship. The electronic stability program can control the longitudinal braking force of each wheel separately, thereby exerting an influence on the lateral force, thereby improving the vehicle's handling performance. When the longitudinal force reaches an extreme value, such as wheel locking, the lateral force is 0. At this time, the lateral movement of the vehicle will be uncontrolled, that is, skidding will occur. At this time, it may not be possible to change lanes or turn as the driver wishes. The electronic stability program can detect and prevent vehicle skidding. When the electronic stability program detects that the vehicle is about to lose control, it will apply braking force to specific wheels to help the vehicle move in the direction the driver expects. When turning, a feasible control strategy is: when the vehicle tends to understeer, the system can apply braking force to the rear wheel on the inside of the turn. Due to the increase in the longitudinal force of this wheel, the lateral force that can be provided is reduced, and a torque to assist the steering of the vehicle body is generated; when there is a tendency to oversteer, the system can apply braking force to the front wheel on the outside of the turn. Due to the increase in the longitudinal force of this wheel, the lateral force that can be provided is reduced, and a torque to resist steering is generated on the vehicle body, thereby ensuring driving stability. Some electronic stability program systems will also reduce the power of the engine when the vehicle loses control.

[0057] When the current weather information meets the skidding weather information, it means that the skidding section is very likely to occur. The vehicle electronic stability system can be activated in advance to deal with or avoid skidding.

[0058] In some embodiments, step S1 includes:

[0059] S003. When the vehicle skids, the vehicle speed, wheel speeds and pedal status are stored.

[0060] When it is determined that the vehicle is skidding, the entire vehicle speed, wheel speeds and pedal status at the time of skidding can also be stored locally or in the cloud as the skidding vehicle speed, wheel speeds and pedal status, to facilitate guidance on vehicle control after the vehicle body electronic system is subsequently turned on; the wheel speeds include, for example, the left front wheel speed, the right front wheel speed, the left rear wheel speed, the right rear wheel speed, etc., and the pedal status includes, for example, acceleration, deceleration, etc.

[0061] In some embodiments, the activating the vehicle body electronic system includes: adjusting the vehicle according to the stored vehicle speed, the wheel speeds, and the pedal status.

[0062] The vehicle is adjusted according to the stored vehicle speed, wheel speed and pedal status. For example, when the current wheel speed is greater than the side slip wheel speed, braking force can be applied to reduce the wheel speed; or when the current vehicle speed is greater than the side slip speed, the vehicle speed can be reduced; or when the current pedal status is acceleration, it can be changed to deceleration. Adjustments are made according to different application scenarios without specific limitations.

[0063] In some embodiments, the step of issuing the side slip warning information further comprises:

[0064] S302: When the vehicle travels to the side slip section, the current vehicle speed, current power mode or current driving lane of the vehicle is obtained.

[0065] The positioning module can be used to determine whether the vehicle is traveling to a side-slip section. When the vehicle is traveling to a side-slip section, the on-board host can obtain the vehicle's current speed, current power mode or current driving lane for subsequent vehicle control. The assisted driving system (NOH, Navigation on HPilot) , ) is to provide driving assistance to the driver and improve driving safety. The assisted driving system can be turned on to control the vehicle; the current power mode is, for example, pure electric mode, hybrid mode, engine mode, etc.; the current driving lane is, for example, the left straight lane, the middle straight lane, the right straight lane, etc.

[0066] S303: When the current vehicle speed is greater than a preset vehicle speed, reduce the current vehicle speed.

[0067] The preset speed may be the aforementioned skidding speed or a custom speed, and is not specifically limited. If the current vehicle speed is high, the vehicle speed is reduced, for example, to below the preset speed, to avoid skidding.

[0068] S304: When the current power mode is an electric-related power mode, the current power mode is switched to a non-electric-related power mode.

[0069] Electric power modes include pure electric mode, hybrid mode and other vehicle power modes involving motor driving, and non-electric power modes include engine mode and other vehicle power modes not involving motor driving. Most side slips occur in rainy and snowy weather. If the current power mode is an electric power mode, the power mode will be switched to a non-electric power mode to avoid high voltage leakage when encountering water.

[0070] S305: When the current driving lane is the same as the side sliding lane, control the vehicle to drive to other lanes.

[0071] If the current driving lane is a side-slip lane, the vehicle is controlled to drive to other lanes except the side-slip lane, so as to avoid side-slipping without changing the travel range.

[0072] In some embodiments, the issuing of sideslip warning information includes:

[0073] S306: Send the sideslip warning information to the instrument on the vehicle side for alarm, or send the sideslip warning information to the display screen on the vehicle side or the mobile side for display, or send the sideslip warning information to the voice module on the vehicle side or the mobile side for broadcast.

[0074] The mobile terminal, such as a mobile phone or tablet, sends a side slip warning message to the vehicle terminal or the mobile terminal to remind the user.

[0075] In some embodiments, the vehicle warning method further includes:

[0076] S2', when there is a flooded section in the current navigation route, obtaining current weather information of the flooded section, wherein the flooded section is a section where flooding has occurred before.

[0077] A flooded road section is a road section that has been stored locally or in the cloud, and the flooded road section means that water has accumulated on the road section. According to the conventional matching algorithm, it can be determined whether there is a flooded road section in the current navigation route. When there is a flooded road section, it means that the vehicle may encounter water when driving on the flooded road section. At this time, the current weather information of the road section can be obtained in real time through the communication module for subsequent judgment. The current weather information can be a simple weather category, such as rainy, sunny, cloudy, foggy, snowy, sandstorm, etc., or a more complex specific weather condition, such as precipitation, etc.

[0078] S3', when the current weather information meets the waterlogging weather information, a waterlogging warning message is issued, wherein the waterlogging weather information is the weather information when waterlogging occurred in the waterlogged road section.

[0079] The flood weather information is information stored locally or in the cloud, and can be weather information when the vehicle waded through the flooded road section. The flood weather information can be a simple weather category, such as moderate rain, heavy rain, etc., or a more complex specific weather condition, such as precipitation, etc.

[0080] Determine whether the current weather information is consistent with the waterlogging weather information. For example, when the waterlogging weather information is a weather category, then it can be determined whether the current weather category is the same as the waterlogging weather category. If they are the same, it means that the flooded section of the road is very likely to be flooded at this time, and a waterlogging warning message can be issued for reminder. For another example, when the waterlogging weather information is precipitation, then it can be determined whether the current precipitation and the waterlogging precipitation are different. If the current precipitation is greater than or equal to the waterlogging precipitation, it means that the flooded section of the road is very likely to be flooded at this time, and a waterlogging warning message can be issued for reminder. The waterlogging warning message is, for example, a reminder message to remind the user that waterlogging will occur on the current navigation route, or a reminder to the user to choose other navigation routes, etc., without specific limitation.

[0081] This method is based on the actual sections of road where flooding has occurred and the weather at the time the flooding occurred, so it is more accurate in judging whether waterlogging has occurred. After determining that there is a flooded section where flooding has occurred in the current navigation route, if the current weather of the section is the same as the weather when the flooding occurred, a waterlogging warning message can be issued to remind users of waterlogging, thereby improving user experience. Users can avoid flooded sections or prepare response strategies in advance to improve safety.

[0082] In some embodiments, information on flooded road sections and flooded weather can be stored when the vehicle or other vehicles are wading through water, or it can be stored in real time through a weather monitoring platform and a road monitoring platform.

[0083] In some embodiments, the vehicle warning method further includes:

[0084] S301', when the current weather information matches the flooded weather information, planning a new navigation route that avoids the flooded road section.

[0085] When it is determined that the current weather information meets the flooding weather information, the map module can be used to re-plan a new navigation route that avoids the flooded section, so as to prevent the vehicle from wading through water when driving along the original navigation route.

[0086] In some embodiments, the step of issuing waterlogging warning information may include:

[0087] S302', obtaining the current driving lane of the vehicle.

[0088] S303', when the current driving lane is the same as the flooded lane, control the vehicle to drive to other lanes, wherein the flooded lane is a lane where water accumulates in the flooded road section.

[0089] The flooded lane is a lane that has been stored locally or in the cloud, and is a lane where water accumulates within a flooded section of the road. If the current driving lane is a flooded lane, the vehicle is controlled to drive to a lane other than the flooded lane, and water wading can be avoided without changing the itinerary.

[0090] In some embodiments, planning a new navigation route to avoid the flooded road section then includes:

[0091] S304': When the vehicle travels to the flooded section, the current water level of the flooded section and the current suspension height of the vehicle are obtained.

[0092] After the vehicle issues a water accumulation warning and plans a new navigation route, if the vehicle does not follow the new navigation route and still drives into a flooded section of road, the current water level of the flooded section and the current suspension height of the vehicle can be obtained, providing a basis for subsequent vehicle control; the current water level can be monitored through the vehicle's exterior rearview mirror ultrasonic ranging radar, and the on-board host can also obtain the current suspension height.

[0093] S305': when the current suspension height is less than or equal to the current water surface height, the current suspension height is increased to a preset height.

[0094] If the current water level is high, for example, higher than the current suspension height, the suspension height can be adjusted to prevent the vehicle from stalling due to wading. The preset height is, for example, 0.05m higher than the current water level, and there is no specific limitation.

[0095] In some embodiments, the vehicle warning method further includes:

[0096] S306', obtaining the maximum wading depth of the vehicle.

[0097] The vehicle-mounted host can obtain the maximum wading depth of the vehicle, and the maximum wading depth can be the highest suspension height, without specific limitation.

[0098] S307': When the maximum wading depth is less than or equal to the current water surface height, the start-stop system of the vehicle is turned off.

[0099] If the current water surface height is higher than the maximum wading depth, it means that the risk of wading is extremely high, so the vehicle's start-stop system will be turned off to prevent the vehicle from stalling in the water; in addition, an alarm message can also be sent to alert the user.

[0100] In some embodiments, the issuing of water accumulation warning information includes:

[0101] S308', sending the water accumulation warning information to the instrument on the vehicle side for alarm, or sending the water accumulation warning information to the display screen on the vehicle side or mobile side for display, or sending the water accumulation warning information to the voice module on the vehicle side or mobile side for broadcasting.

[0102] The mobile terminal, such as a mobile phone or tablet, sends water accumulation warning information to the vehicle terminal or mobile terminal to remind the user.

[0103] In some embodiments, the vehicle drives to the flooded road section, and then includes:

[0104] S309': When the engine of the vehicle is turned off, an operation guidance message or a distress message is sent.

[0105] Operational guidance information is used to guide users on what to do after the vehicle is turned off, such as prohibiting re-ignition, to avoid more serious hazards. SOS information includes information about the vehicle being turned off and waiting for rescue, or rescue phone numbers and addresses, etc.

[0106] In some embodiments, the sending of the operation guidance information or the distress message includes:

[0107] S310', sending the operation guidance information to a display screen of a vehicle or mobile terminal for display, or sending the operation guidance information to a voice module of a vehicle or mobile terminal for broadcast; or sending the distress message to a rescue terminal.

[0108] The mobile terminal is, for example, a mobile phone or a tablet, which sends operation guidance information to the vehicle terminal or the mobile terminal to guide the user operation; the rescue terminal is, for example, a nearby 4S store, etc., which is not specifically limited.

[0109] In some embodiments, the execution logic of the vehicle warning method is as follows: Figure 2 As shown, when the ESP function of the vehicle is triggered, the sideslip information can be stored, such as the sideslip road section, sideslip weather information, etc. When the vehicle encounters the same road section and weather, a sideslip warning message can be issued to remind the user that there is a risk of sideslip ahead, please reduce the speed and turn on the ESP function. If the vehicle has turned on the NOH function, the vehicle will be controlled according to the current speed, current lane or current power mode to avoid sideslip.

[0110] In some embodiments, the execution logic of the vehicle warning method is as follows: Figure 3As shown, the vehicle or cloud platform can store water accumulation information, such as flooded road sections, flooded weather information, etc. When the vehicle encounters the same road section and weather, it can issue water accumulation warning information and provide detour navigation suggestions. If the vehicle does not detour, the vehicle can be controlled according to the vehicle's maximum wading depth, current suspension height and current water surface height. If the vehicle accidentally stalls, a stall suggestion can be provided.
