Abstract

The invention discloses a vehicle body gesture control system for an active suspension of a vehicle. The vehicle body gesture control system comprises a sonar or laser sensor and four vehicle frame height sensors, wherein the sonar or laser sensor is mounted on a vehicle body, and the four vehicle frame height sensors are mounted on the left and right sides of the vehicle body; and rotation speed information of left and right vehicle wheels are respectively obtained through left and right ABS sensors, and a control unit is used for calculating the speed of the vehicle, whether to turn and turning radius information according to the rotation speed difference of the left and right vehicle wheels. An air suspension is adopted in the vehicle; and the control unit calculates the height of the vehicle according to factory rigidity parameters of the suspension and height information output by the height sensors, synthesizes weight, pavement information, height information, vehicle speed, a turning will of a driver and turning radius information and controls the left and right airbags release air so as to adjust a vehicle body gesture, so that the level of the vehicle body gesture during the straight driving on any pavement is guaranteed, or the vehicle body inclines by a certain degree during the turning on any pavement, a centripetal force required by the turning of the vehicle is provided, and the safety and comfort feel of the vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle body attitude control system for active suspension suspension. Background technique [0002] When the car is turning, due to the centripetal force, the body will tilt to a certain extent, especially for towed vehicles, the consequences caused by the tilt of the body are more serious, which brings great potential safety hazards to drivers and pedestrians, and also causes partial wear of tires. The life of the tire is reduced; at the same time, when the vehicle is running on different flat roads, the uneven road greatly reduces the comfort. [0003] Therefore, how to provide a control system for stabilizing the vehicle body on uneven roads or turning is an urgent problem to be solved at present. Contents of the invention [0004] The invention proposes a vehicle body posture control system with an active suspension suspension, which solves the problem of vehicle body ...
