Problems solved by technology
However, with manual adjustment, the driver needs to manually switch the mode of the air suspension system frequently when encountering complex road conditions
When the automatic adjustment method is adopted, there is repeated adjustment of the air suspension caused by changes in road traffic conditions on a single road. For example, traffic jams on the expressway will cause the air suspension to repeatedly adjust its working mode with the speed of the vehicle.

Embodiment Construction
[0050] The present application will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0051]At present, according to different road conditions and vehicle speed states, the air suspension can be set to several working modes manually or automatically, and these working modes include standard mode, off-road mode, and high-speed mode. After the air suspension system is switched to the standard mode, it is more suitable for urban roads, and the vehicle height is adjusted to the middle position at this time. After the air suspension system is switched to off-road mode, it is more suitable for off-road sections. At this time, the vehicle body height is adjusted to a higher position, and the vehicle has high passability and can easily pass through uneven roads. After the air suspension system is switched to high-speed mode, it is more suitable for high-speed road sections, and the body is adjusted to a lower position at high speed. ...

The present application discloses a method and system for automatically switching operation modes of an air suspension system, relating to the technical field of automobile suspension, including setting the default operation mode of the air suspension system as a standard mode. Collect navigation information in real time, and judge whether the vehicle has entered the highway section according to the navigation information. If so, adjust the current operating mode of the air suspension system to a high-speed mode. If not, the current operating mode of the air suspension system is switched to an off-road mode in combination with vehicle stability and vehicle speed. The application can switch the air suspension system to a suitable operation mode under different road conditions, avoid the frequent speed-dependent adjustment problem of the existing air suspension mode switching method, improve the adjustment accuracy of the operation mode of the air suspension system, and improve the control efficiency.
Description
technical field [0001] The present application relates to the technical field of automobile suspension, in particular to a method and system for automatically switching operation modes of an air suspension system. Background technique [0002] Automobile suspension is one of the important parts of the vehicle. As the force transmission device connecting the frame (or body) and the axle (or wheel), it is not only an important part to ensure the comfort of the ride, but also to ensure the safety of the car. important components. The car suspension can buffer the impact force transmitted to the frame or body by the uneven road surface when the car is running, attenuate the vibration of the car, and ensure the driving comfort of the car. [0003] A high-quality SUV should not only have the comfort of a car, but also take into account the passing performance of an off-road vehicle. The air suspension system is the best choice to achieve this goal. The air suspension system uses ...
