Abstract:
The present disclosure relates to an electric control leveling valve for a vehicle, comprising: a vehicle height variation detection device, which is used for detecting a height variation of a vehicle body of the vehicle and generating a height variation electrical signal characterizing the height variation of the vehicle body; a control device, which generates a corresponding valve control command based on the height variation electrical signal; and a valve device, which is in gaseous coupling to a secondary suspension system of the vehicle and adjusts air mass of the secondary suspension system based on the valve control command. The present disclosure further relates to a corresponding vehicle, comprising such an electric control leveling valve. In some embodiments, the control can be made more flexible and active to facilitate diagnosis of faults of the electric control leveling valve, so that the valve can be replaced in time.
