Problems solved by technology

[0003] The traditional suspension system is a passive suspension system such as metal spring suspension, rubber suspension, etc. The characteristics of each component in the passive suspension cannot be adjusted, and it can only passively absorb energy and ease the impact, which has a strong impact on the vehicle and the road surface. Shock load, reducing the service life of vehicles and roads, etc.
The passive suspension of the transmission has fixed suspension stiffness and suspension damping. The starting point of the design is to meet the compromise between the ride comfort and handling stability of the car, but it cannot solve the problem of satisfying the balance between ride comfort and handling stability at the same time. contradictory requirements

Abstract

The invention provides a vehicle air suspension control system and a control method thereof. The vehicle air suspension control system comprises an air compressor, a drying tank, an air storage tank, an electromagnet valve unit, an electric control unit, four air bags, four pressure sensors, three height sensors and a functional panel, wherein the air compressor, the drying tank and the air storage tank are connected in sequence through an air path; the other end of the air storage tank is connected with the electromagnetic valve unit; the electric control unit is electrically connected with the air compressor, the drying tank, the electromagnetic valve unit, the pressure sensors, the height sensors and the functional panel respectively. By adoption of the vehicle air suspension control system, suspension lifting and falling control can be achieved, and air path fault alarm can be made, back-blow reduction operation on the drying tank is achieved, the air can be dried, the airbags can be protected, the service life can be prolonged, and the cost can be lowered.

Description

technical field [0001] The invention belongs to the field of suspension, and in particular relates to a vehicle air suspension control system and a control method thereof. Background technique [0002] Suspension system is an integral part of the car. It elastically connects the body and axles. When the car is running, it is used to buffer the impact force transmitted to the frame or body from uneven ground and attenuate the impact caused by it. Vibration to ensure that the car can run smoothly. [0003] The traditional suspension system is a passive suspension system such as metal spring suspension, rubber suspension, etc. The characteristics of each component in the passive suspension cannot be adjusted, and it can only passively absorb energy and ease the impact, which has a strong impact on the vehicle and the road surface. Shock load, reducing the service life of vehicles and roads and other shortcomings. The passive suspension of the transmission has fixed suspension...
