[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0024] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0025] In this embodiment, a vehicle air suspension control method is provided. Figure 1 is a flow chart of a vehicle air suspension control method provided by an exemplary embodiment. Figure 1 Said method may include the following steps:

[0026] Step S101, obtaining the slope value of the road on which the vehicle is located and the speed value of the vehicle.

[0027] For example, the slope value of the road where the vehicle is located can be obtained at intervals of a target preset time. The target preset time can be set according to the actual usage scenario to achieve the effect of obtaining the slope value of the road where the vehicle is located in real time. For example, a slope sensor can be installed at the front and rear parts of the vehicle to collect the slope value of the road where the vehicle is located. As another example, if Figure 2 As shown, it is a schematic diagram of a vehicle air suspension control system provided based on an embodiment of the present disclosure, and the slope value can be obtained based on a map slope sensor, and the map slope sensor can be a high-precision map, that is, based on the positioning of the vehicle in the high-precision map, a slope signal corresponding to the positioning location is obtained, and the slope value corresponding to the slope signal is used as the slope value of the road where the vehicle is located. For example, the current speed value of the vehicle can be collected and obtained by a speed sensor installed on the vehicle.

[0028] Step S102, when the vehicle has not entered the long downhill operating mode, the continuous time when the slope value of the road where the vehicle is located is within the target slope range is greater than a first preset time length, and the speed value is greater than a speed threshold, determine that the vehicle switches to the long downhill operating mode.

[0029] Among them, the default mode of vehicle driving is the normal mode, that is, a mode other than the long downhill working mode, which can be a control method for the air suspension of the vehicle in the prior art.

[0030] Among them, the long downhill working mode is used to indicate that the road surface on which the vehicle is currently traveling is a downhill road surface. In this long downhill working mode, the height of the vehicle head will be lower than the height of the vehicle tail, and the vehicle itself will have a certain pitch angle, which affects the comfort of the user driving the vehicle. Furthermore, in the long downhill working mode, in order to ensure the speed of the vehicle going downhill, the brakes may be used frequently, resulting in thermal decay, which affects the safety of the vehicle. Based on this, the long downhill working mode can be identified in the present disclosure, so that the vehicle driving state in this mode can be controlled later to improve the safety of vehicle driving.

[0031] Among them, the target slope range can be set based on the actual application scenario and the experience value, and the target slope range can be determined by setting the upper limit value of the slope and the lower limit value of the slope. For example, the target slope range is set to 3%-15%. According to whether the slope value is within the target slope range, it is preliminarily determined whether the vehicle is switched to the long downhill working mode. When the slope value is greater than the upper limit value of the slope of the target slope range, the height of the air suspension of the vehicle can be kept unchanged to ensure the safety of the vehicle. When the slope value is less than the lower limit value of the slope of the target slope range, the vehicle body is basically horizontal at this time, and the height of the air suspension of the vehicle can also be kept unchanged at this time. In this embodiment, the continuous time when the slope value of the road surface where the vehicle is located is greater than the first preset time length indicates that the road surface where the vehicle is located has always had a slope, and at this time, it can be considered that the road surface where the vehicle is located is a long downhill road surface. In addition, the speed of the vehicle can be obtained while obtaining the slope value, and the speed value of the vehicle can also be obtained when it is determined that the slope value meets the conditions described above, so as to further determine whether the vehicle is in a driving state on a long downhill road surface. If the speed value is greater than the speed threshold, it means that the vehicle is in a driving state, and at this time, it can be determined that the vehicle is switched to the long downhill operating mode to avoid switching the vehicle to the long downhill operating mode when the vehicle is in a stopped state. For example, the speed threshold can be set to be greater than zero, and the present disclosure is set to 10 km / h.

[0032] Step S103, determining a first target height of the front air suspension of the vehicle according to the slope value and the wheelbase value of the vehicle.

[0033] For example, the wheelbase value is a fixed value, and the wheelbase values ​​of different models are different. Specifically, a mini car refers to a car with a wheelbase of less than 2400mm; a small car refers to a car with a wheelbase between 2400mm-2550mm; a compact car refers to a car with a wheelbase between 2550mm-2700mm; a medium-sized car refers to a car with a wheelbase between 2700mm-2850mm; and a medium-to-large car refers to a car with a wheelbase between 2850mm-3000mm.

[0034] For example, a small car is compared with a medium-sized car. When the vehicles are on a certain slope and the front wheels of the medium-sized car are in the same position as the front wheels of the small car, the height of the rear wheels of the medium-sized car from the ground is higher than that of the rear wheels of the small car. In order to keep the vehicle body level, the height to which the front wheels of the medium-sized car are raised needs to be higher than the height to which the front wheels of the small car are raised. Therefore, the factors that keep the vehicle body level during driving are related to the slope of the road on which the vehicle is located and the wheelbase value of the vehicle. In this embodiment, the first target height of the front air suspension of the vehicle is determined by the slope value and the wheelbase value of the vehicle, thereby achieving precise control of the vehicle air suspension to facilitate horizontal control of the vehicle body.

[0035] Step S104: raising the height of the front air suspension according to the first target height, thereby reducing the height difference between the head and the tail of the vehicle.

[0036] For example, the first target height can be used as the target height of the front air suspension of the vehicle to adjust its height so that the height of the front air suspension of the vehicle is increased, thereby minimizing the height difference between the head and the tail of the vehicle. For example, the height of the front air suspension can be adjusted by the solenoid valve of the air suspension system. Figure 2 As shown, the corresponding current value can be calculated according to the first target height, so that the current driver 3 can be controlled to output to the air suspension system solenoid valve, and then the front suspension air spring 5 can be connected to the high-pressure gas source based on the air suspension system solenoid valve 4, and the high-pressure gas can be filled into the front suspension air spring 5, thereby increasing the height of the front suspension air spring 5. In this process, the height value of the front suspension air spring detected by the height sensor and the air pressure value of the front suspension air spring detected by the air pressure sensor can be adjusted according to the PID algorithm to achieve height adjustment of the front air suspension.

[0037] In the above technical solution, the driving state of the vehicle can be monitored by obtaining the slope value of the road where the vehicle is located and the speed value of the vehicle. After that, it can be identified whether the vehicle is in a long downhill driving state according to the slope value and the speed value, so that when the vehicle switches to the long downhill working mode, the height of the front air suspension of the vehicle can be increased. On the one hand, the working mode of the vehicle can be accurately identified, and on the other hand, the situation in which the vehicle is in the long downhill working mode can be adjusted to ensure the matching between the air suspension control in the vehicle and the actual driving state of the vehicle. In addition, when the vehicle is in the long downhill working mode, by increasing the height of the front air suspension of the vehicle and reducing the height difference between the head and the tail of the vehicle, the frontal area can be increased for auxiliary braking, thereby reducing the frequency of use of the brake to a certain extent, helping to reduce the thermal decay effect of the brake due to long-term use, and at the same time, it can ensure the level of vehicle driving to a certain extent, improve the vehicle safety performance and improve the driving comfort of the vehicle.

[0038] In a possible embodiment, an exemplary implementation of determining a first target height of the front air suspension of the vehicle according to the slope value and the wheelbase value of the vehicle is as follows. This step may include:

[0039] A first height value corresponding to the front air suspension is determined according to a current speed value of the vehicle.

[0040] The first height value is used to indicate the height value of the air suspension corresponding to the vehicle traveling on a horizontal road surface in a state corresponding to the current speed value, that is, the basic height of the air suspension. When traveling on a horizontal road surface, the heights of the front and rear air suspensions can be controlled to be the same. Generally, the higher the vehicle's driving speed, the lower the required air suspension height value. Therefore, in this embodiment, the corresponding relationship between the speed value and the height value of the air suspension can be obtained through preliminary experiments. The corresponding relationship can be determined based on preliminary experiments. Therefore, after obtaining the current speed value of the vehicle, the corresponding relationship can be queried to use the height value queried from the corresponding relationship as the first height value.

[0041] Afterwards, a second height value corresponding to the front air suspension is determined according to the current slope value and the wheelbase value of the vehicle.

[0042] The second height value is used to represent the compensation height of the front air suspension required for controlling the vehicle to be in a horizontal state under the current driving state. For example, the product of the current slope value and the wheelbase value can be determined as the second height value, thereby realizing accurate calculation of the compensation height of the front air suspension.

[0043] The sum of the first height value and the second height value is determined as the first target height.

[0044] Through the above scheme, the target height of the front air suspension can be determined by determining the basic height and compensation height corresponding to the current driving state of the vehicle. On the one hand, the accuracy of the air suspension height can be guaranteed, and on the other hand, the height of the air suspension can be adapted to the driving state of the vehicle, thereby improving the accuracy and effectiveness of the vehicle's air suspension control and enhancing the user's driving experience of the vehicle.

[0045] In a possible embodiment, the method may further include:

[0046] The height of the rear air suspension of the vehicle is adjusted to the first height value.

[0047] In this embodiment, by adjusting the height of the rear air suspension, the height of the rear air suspension can be matched with the driving state of the vehicle, and by raising the height of the front air suspension, the vehicle can ensure that the vehicle body can travel horizontally in the long downhill working mode. Therefore, through the above technical solution, the height of the front air suspension and the rear air suspension of the vehicle can be adjusted respectively, ensuring the comprehensiveness and rationality of the height adjustment of the vehicle's air suspension, and further improving the user experience.

[0048] In a possible embodiment, the method may further include:

[0049] When the time when the vehicle switches to the long downhill operating mode reaches a second preset time, if the slope value of the road surface on which the vehicle is located is less than the slope threshold for a continuous time greater than a third preset time, it is determined that the vehicle exits the long downhill operating mode.

[0050] After the vehicle switches to the long downhill working mode and drives for a second preset time, it can be further determined whether the vehicle needs to exit the long downhill working mode to avoid frequent rise and fall of the air suspension height and reduce the driving and riding experience. For example, the slope threshold value can be less than the lower limit of the slope of the target slope range. If the continuous time of the slope value of the road where the vehicle is located being less than the slope threshold value is greater than the third preset time, it means that the vehicle is driving on a flat road at this time, and the long downhill working mode can be exited at this time to accurately control the air suspension of the vehicle.

[0051] The second target height corresponding to the front air suspension is determined according to the current speed value of the vehicle. When the vehicle exits the long downhill working mode, the current speed value of the vehicle can be obtained by a speed sensor, and the second target height can be further determined based on the corresponding relationship. The calculation method of the second target height is the same as the determination method of the first height value described above, and will not be repeated here.

[0052] The height of the front air suspension is lowered according to the second target height. Furthermore, the heights of the front air suspension and the rear air suspension of the vehicle are adjusted to the second target height. For example, the height of the air suspension can be adjusted by the solenoid valve of the air suspension system, such as connecting the front suspension air spring to the atmosphere so that the gas in the front suspension air spring is discharged into the atmosphere, thereby reducing the height of the front suspension air spring to achieve the height adjustment of the front air suspension. Similarly, during the height adjustment process, the height can be adjusted by PID method based on the height value and air pressure value of the front suspension air spring. For the rear air suspension, if it needs to increase or decrease in height, it can be adjusted by the method described above. If its current height is the same as the second target height, the pressure of the rear air suspension air spring can be kept unchanged to keep the height of the rear suspension air spring unchanged at the second target height.

[0053] Therefore, the control mode can be determined according to the real-time state of the vehicle during driving, so that the height of the air suspension can be smoothly switched between the state of going down a long slope and the state of driving on a flat road, so that the height of the air suspension matches the driving state of the vehicle on a flat road, thereby improving the accuracy of air suspension control and enhancing the user's driving experience.

[0054] In a possible embodiment, an exemplary implementation manner of raising the height of the front air suspension according to the first target height is as follows, and this step may include:

[0055] If the first target height is greater than a height threshold, the height threshold is determined as an adjustment height of the front air suspension.

[0056] The height threshold may be set based on a maximum height that the front air suspension can reach, and the height threshold may be less than or equal to the maximum height that the front air suspension can reach.

[0057] If the first target height is less than or equal to the height threshold, determining the first target height as the adjustment height of the front air suspension;

[0058] The height of the front air suspension is raised to the adjusted height. The method for raising the height of the air suspension has been described in detail above.

[0059] Therefore, in the above technical solution, after the first target height is determined, it can be adjusted according to the first target height within the adjustment range allowed by the front air suspension, thereby ensuring the safety and accuracy of the vehicle's air suspension height adjustment, improving the user's driving experience, and further ensuring the vehicle's driving safety and improving the user's experience.
