Method for adjusting height of vehicle body through height sensor

Abstract

The invention provides a method for adjusting the height of a vehicle body through a height sensor. The method comprises the steps of measuring vehicle body height signals of a vehicle in real time through the height sensor arranged on the vehicle, collecting two paths of rear axle height sensor signals, judging whether a vehicle door is opened according to the rear axle height sensor signals, analyzing the rear axle height sensor signals to obtain the current height value of the vehicle body and judging whether the current height value of the vehicle body is higher than first preset value if the vehicle door is not opened, judging whether the current height value of the vehicle body is higher than second preset value if the current height value of the vehicle body is not higher than the first preset value, and turning off a solenoid valve to complete vehicle body height adjustment if the height value of the current vehicle body is not lower than the second preset value. The method for adjusting the height of the vehicle body through the height sensor can ensure that the vehicle body height is located in a best position and improve the smoothness of the vehicle.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a method for adjusting the height of a vehicle body through a height sensor. Background technique [0002] Since the beginning of the 21st century, with the improvement of living standards and the increase of automobile consumption, the intelligence of the vehicle electronic control system has been continuously improved, and the functions of the corresponding body control system have become more and more humanized. [0003] With the rapid development of integration and intelligence, traditional suspension technology is far from meeting the needs of modern body control systems. The current suspension system is considered to be driving on various roads, so the height will not be too low, and the distance from the ground Relatively fixed, when driving at high speed, because the height of the chassis changes less than usual, the center of gravity is higher when driving at high speed, t...

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