[0067] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0068] Research has found that the vehicle suspension height is a very important vehicle performance parameter that directly affects the vehicle's passability, especially when the road conditions are poor. For example, when driving in water or snow, it is easy for the chassis to get flooded or the engine to stall and get stuck, which can cause damage to the vehicle's engine, battery and other components.

[0069] Based on this, an embodiment of the present application provides a method for controlling a vehicle suspension to improve the vehicle's passability under special and extreme weather conditions and enhance driving safety.

[0070] See also Figure 1 , Figure 1 This is a flow chart of a vehicle suspension control method provided in an embodiment of the present application. Figure 1 As shown in , the control method provided in the embodiment of the present application can be applied to a vehicle-mounted controller, specifically including:

[0071] S101. Predict whether there is water accumulation on the road ahead based on environmental data of the current location of the vehicle.

[0072] In this step, the environmental data around the current position of the vehicle can be obtained through the vehicle-mounted components, and the position of the road ahead can be determined based on the current position and driving direction of the vehicle, and then the presence of water on the road ahead can be predicted based on the environmental data.

[0073] In a possible implementation, step S101 may include:

[0074] S1011. Determine a current precipitation signal according to the real-time rainfall detected by the vehicle body rain sensor.

[0075] Among them, precipitation signals include weak precipitation signals, moderate precipitation signals and strong precipitation signals. These precipitation signals can be divided by presetting thresholds. Precipitation includes many forms, such as rain, snow, hail, freezing rain, etc. Here, snowfall will also be converted into equivalent liquid water height for unified measurement and comparison.

[0076] The main working mode of the rain sensor is to detect the amount of rain falling on the front windshield, link the car wipers, and control the wiper action to keep the driver and passengers' vision clear. For example, in the weather without rain or with tiny raindrops, the wiper does not work, or works in an intermittent mode (low frequency). At this time, the sensor can only receive a very weak signal. At this time, the precipitation signal received by the on-board controller is basically close to 0, that is, a weak precipitation signal. In light rain, the corresponding wiper intermittent mode (medium frequency) action, at this time the sensor will receive a medium-intensity signal, there are a certain number of raindrops on the windshield, and it is determined to be a medium-intensity precipitation signal. In moderate or heavy rain, corresponding to the low-speed and high-speed continuous modes of the wiper, the relevant rain sensor identifies the signal as strong; or, in the heavy rain stage, the field of vision is unclear, the rain signal is the maximum, and it is determined to be a strong precipitation signal.

[0077] In addition, since there is a corresponding relationship between the precipitation signal detected by the above-mentioned rain sensor and the operation mode of the wiper, in the embodiment of the present application, the current precipitation signal can also be determined by detecting the operation mode of the wiper.

[0078] S1012: If the current precipitation signal is a heavy precipitation signal, determine that there is water accumulation on the road ahead.

[0079] Here, when there is a signal of heavy rainfall, it can be directly determined that there is water accumulation on the road ahead and the suspension height needs to be raised.

[0080] S1013. If the current precipitation signal is a medium-intensity precipitation signal, obtain cloud-based environmental data and / or environmental data detected by other vehicle body components; and predict whether there is water accumulation on the road ahead based on the cloud-based environmental data and / or environmental data detected by other vehicle body components.

[0081] In this step, when there is a moderate intensity precipitation signal, it is not accurate to predict whether there is water accumulation on the road ahead based on the rain sensor on the vehicle body alone due to the influence of factors such as the terrain of different road sections and drainage capacity. Therefore, the cloud environment data and / or the environment data detected by other vehicle body parts can be combined to further coordinate the prediction of whether there is water accumulation on the road ahead.

[0082] Specifically, for cloud environment data, when the cloud environment data indicates that there is a flooded road section around the current location, or the precipitation in the current period of the local area to which the current location belongs exceeds a preset threshold, it can be predicted that there is water on the road ahead. For example, when the cloud map indicates that there is water or snow on the local map; and / or the cloud weather system indicates that there is heavy rain and snow, and you should travel with caution, it can be predicted that there is water on the road ahead.

[0083] And / or, the operating data of other vehicle body components include at least one of the following: whether the electronic stability program system ESP is activated, the road surface image taken by the vehicle-mounted camera, and the road surface point cloud scanned by the vehicle-mounted radar.

[0084] Among them, the auxiliary system will be involved in the driving process of the vehicle due to road conditions such as rain and snow. For example, the ESP system helps the driver maintain control of the vehicle by integrating and coordinating the vehicle's braking system and engine management system, especially on slippery roads. Therefore, when the electronic stability program system ESP is activated, it can be predicted that there is water on the road ahead. And, based on the road image, it can be identified by an image recognition algorithm whether there is water on the road ahead; and, based on the road point cloud, it can be identified by a point cloud recognition algorithm whether there is water on the road ahead.

[0085] Furthermore, the embodiments of the present application can also predict whether there is water accumulation on the road ahead based only on one or a combination of any two or more of the vehicle body rain sensor, cloud environment data, and operating data of other vehicle body components.

[0086] S102: If yes, determine whether the suspension height of the vehicle is currently adjustable according to the vehicle driving parameters.

[0087] In a possible implementation, the vehicle driving parameters include: user-preconfigured function parameters, vehicle speed, suspension state, and vehicle driving mode; then step S102 may include:

[0088] S1021. Determine whether the vehicle has an automatic suspension height adjustment function enabled according to the function parameters pre-configured by the user.

[0089] In this step, the automatic suspension height adjustment function is turned on by default, and relevant soft switches can be set in the vehicle computer. Users can configure the function parameters by operating the soft switches to turn the automatic suspension height adjustment function on or off. In addition, the specific detailed parameters of the automatic suspension height adjustment function can also be set.

[0090] S1022: If the automatic suspension height adjustment function is turned on, determine whether the vehicle speed exceeds a preset threshold.

[0091] In this step, when driving at high speeds, such as above 60 km / h, the suspension will not be changed, so as to prioritize the user's driving experience and avoid adverse effects on the stability, handling and safety of the vehicle.

[0092] S1023: If the preset threshold is not exceeded, determine whether the suspension state has been adjusted to the highest height.

[0093] Here, if the suspension state has been adjusted to the preset maximum suspension height, the suspension cannot be raised any further.

[0094] S1024: If the height has not been adjusted to the highest level, determine whether the vehicle driving mode is a sports mode.

[0095] S1025: If the vehicle driving mode is a non-sports mode, determine that the vehicle currently has an adjustable suspension height.

[0096] Here, because the Sport mode is designed to provide a more aggressive and dynamic driving experience, the main focus is on the vehicle's handling and responsiveness. At this time, the vehicle's power output and handling characteristics have been adjusted to adapt to more intense driving conditions. If the suspension height is raised at this time, it may increase the risk of vehicle instability when driving at high speeds or making sharp turns, thus affecting driving safety and driving experience. Therefore, the suspension height cannot be adjusted in Sport mode.

[0097] Furthermore, if the vehicle currently cannot adjust the suspension height, a suspension lifting instruction can be generated and stored based on environmental data; based on maps, traffic light information, etc., the suspension height can be adjusted when conditions are met such as when parking or on low-speed roads.

[0098] S103: If adjustable, generate a suspension lifting instruction according to the environmental data.

[0099] In this step, the lifting height of the suspension can be determined according to the environmental data, and then a suspension lifting instruction is generated. In specific implementation, step S103 may include:

[0100] The continuous precipitation amount is calculated according to the current precipitation signal; the target suspension height is determined according to the continuous precipitation amount; and the suspension lifting instruction is generated according to the target suspension height.

[0101] For example, the continuous precipitation can be calculated based on the rainfall amount × rainfall time, the water accumulation depth can be estimated based on the continuous precipitation, and then the target suspension height can be determined by the water accumulation depth. For example, the lifting amount can be designed to be 5mm higher than the calculated water accumulation amount. For example, in heavy rain weather, the suspension height can also be directly adjusted to the highest height. Then, a suspension lifting instruction is generated according to the target suspension height.

[0102] S104: Adjust the suspension height of the vehicle according to the suspension lifting instruction.

[0103] In this step, the action of the underlying actuator can be controlled according to the suspension lifting instruction, so as to adjust the suspension height to the target suspension height. The specific control principle can refer to the suspension control principle in the prior art, and this application does not make any limitation here.

[0104] Furthermore, after predicting whether there is water on the road ahead of the current position of the vehicle, the control method further includes:

[0105] If so, water accumulation warning information is generated and the water accumulation warning information is prompted through the vehicle-mounted equipment.

[0106] The vehicle-mounted equipment may be a vehicle-mounted audio device or a vehicle-mounted display device, etc. Taking the vehicle-mounted display device as an example, it may include: HUD system, in-vehicle central control display screen, in-vehicle co-pilot screen, in-vehicle rear seat screen, and in-vehicle central TV / projector and other entertainment equipment, etc. The in-vehicle display device displays water accumulation warning information to remind users to drive carefully.

[0107] A vehicle suspension control method provided in an embodiment of the present application predicts whether there is water on the road ahead based on environmental data of the vehicle's current position; if so, determines whether the vehicle's suspension height is currently adjustable based on vehicle driving parameters; if adjustable, generates a suspension lifting command based on the environmental data; and adjusts the vehicle's suspension height based on the suspension lifting command.

[0108] In this way, when it is predicted that there is water accumulation on the road ahead and the vehicle can adjust the suspension height, a suspension lifting command is automatically generated to adjust the suspension height, thereby improving the vehicle's passability under special and extreme weather conditions and improving driving safety.

[0109] Among them, a rain sensor is used to detect the intensity and duration of precipitation. According to the relevant data, data analysis is completed in the controller. According to the analysis conclusion, the integrated control system is used to send relevant instructions to the adjustable suspension system to adjust the suspension height, so as to realize intelligent adjustment of the vehicle without user operation to achieve better vehicle passability.

[0110] Furthermore, in the embodiments of the present application, not only rain sensors can be used, but also relevant information from multiple sources such as the in-vehicle cloud map, cloud weather, navigation, etc. can be read to perform data analysis and processing. For example, if there is flooded road surface in the navigation and heavy rain information in the weather, the vehicle suspension adjustment can be completed to assist users in having a better driving experience in daily use of the vehicle.
