Embodiment Construction

[0052] Such as figure 1 As shown, an electronically controlled air suspension vehicle attitude control system of the present invention includes a gyro sensor 5 and four vehicle body height sensors. The vehicle height sensors are the front left vehicle height sensor 19, the vehicle height sensor 2, the vehicle height sensor 15 and the vehicle height sensor 6. The four vehicle height sensors are used to detect the front left, front right, rear left and rear right suspensions in real time respectively. dynamic stroke information, wherein, the vehicle body height sensor 19 detects the dynamic stroke f of the front left suspension in real time dfl Information, vehicle height sensor 2 real-time detection of front right suspension dynamic stroke f dfr Information, vehicle body height sensor 15 real-time detection rear left suspension moving stroke f drl Information, vehicle body height sensor 6 real-time detection rear right suspension moving stroke f drr information. The gyro se...

Abstract

The invention discloses an automobile electronic control air suspension whole automobile attitude control system and method in the technical field of automobile air suspensions. The system comprises agyroscope sensor for detecting the automobile body bank angle and the automobile body pitch angle, and four automobile body height sensors for detecting movable journey information of a front left suspension, a front right suspension, a rear left suspension and a rear right suspension, the gyroscope sensor and the output ends of the automobile body height sensors are connected with the input endof a whole automobile attitude controller through CAN buses, the whole vehicle attitude controller is composed of a front left air spring control module, a front right air spring control module, a rear left air spring control module and a rear right air spring control module, the output end of the whole automobile attitude controller is connected with the input end of an electromagnetic valve drive circuit, and the output end of the electromagnetic valve drive circuit is connected with eight electromagnetic valves respectively. The whole automobile attitude controller determines a charging anddischarging control signal capable of keeping the automobile body attitude stability in the driving process according to the suspension movable journeys, the automobile body bank angle and the automobile body pitch angle, and the automobile body attitude is rapidly and effectively adjusted by an automobile under complex working conditions.

Description

technical field [0001] The invention relates to the technical field of air suspension of automobiles, in particular to a control system and a control method for controlling the attitude of the whole automobile. Background technique [0002] The air suspension uses air springs as elastic components, which can obtain a lower natural frequency of the suspension system. When the load changes, the natural frequency of the system does not change much, thereby improving the ride comfort of the car; on the other hand, the vehicle passes through the air The active control of spring inflation and deflation can meet the requirements of body posture under different working conditions. [0003] In the literature with the Chinese patent publication number CN105599558A, a joint control method of electronically controlled air suspension body height adjustment and vehicle attitude is proposed. The vehicle height adjustment at the four corners of the vehicle is corrected, which can realize t...
