AHC height control system and vehicle

Abstract

The invention provides an AHC height control system and a vehicle. The AHC height control system comprises a pressure sensor, a height sensor, a vehicle door state detector, a mode selector, a single-chip microcomputer, an air spring, an air storage stank, an air compressor, an exhaust valve, a display screen and a solenoid valve, wherein the pressure sensor, the height sensor, the vehicle door state detector, the mode selector, the air compressor, the exhaust valve, the display screen and the solenoid valve are respectively in communicating connection with the single-chip microcomputer. According to the AHC height control system and the vehicle, signals sent by all the sensors of a vehicle body are received to control a pump machine of the air compressor, the exhaust valve and the solenoid valve, and therefore the air pressure in the air spring is adjusted, and the aim of keeping the height of the vehicle body unchanged is achieved. When the load capacity of the vehicle is increased or lowered, the system can inflate or deflate the air spring so that the height of the vehicle body can be at the optimal position all the time, and the ride comfort of the vehicle is improved.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to an AHC height control system and a vehicle. Background technique [0002] At present, most domestic automobile suspensions still use leaf spring suspensions. The leaf spring suspension has the characteristics of large weight and increased vehicle quality. When the car is driving on a bumpy road, the stiffness and height of the leaf spring suspension cannot be adjusted, and the comfort and handling are not good. Or when the load of the car changes, It also cannot automatically adjust the height of the vehicle body. [0003] With the rapid development of integration and intelligence, the traditional suspension technology is far from meeting the needs of modern body control systems. The current suspension system is considered to be able to drive on various roads, so the height will not be too low. The ground distance is relatively fixed. When driving at high speed, the height of the...

The leaf spring suspension has the characteristics of large weight and increased vehicle quality. When the car is driving on a bumpy road, the stiffness and height of the leaf spring suspension cannot be adjusted, and the comfort and handling are not good. Or when the load of the car changes, Can't automatically adjust the height of the car

[0003] With the rapid development of integration and intelligence, the traditional suspension technology is far from meeting the needs of modern body control systems. The current suspension system is considered to be able to drive on various roads, so the height will not be too low. The ground distance is relatively fixed. When driving at high speed, the height of the chassis changes less than usual, so the center of gravity is higher when driving at high speed, the comfort is poor, and it may cause danger.
