Embodiment Construction

[0065] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0066] Such as figure 1 As shown, the passenger car anti-rollover control system of the system described in the present invention includes an early warning module 1, a decision-making module 2 and an execution module 3, wherein the early warning module 1 collects the pressure information inside the air spring of each wheel of the passenger car according to the pressure sensor 10, through which Calculate the vertical load state of each wheel, and judge the running state of the bus according to the vertical load state and the vehicle running state; the decision-making module 2 determines the opening and closing time of the height control solenoid valve 11 and the brake solenoid valve according to the rollover information transmitted by the early warning module , and transmit th...

Abstract

The invention discloses a passenger car anti-rollover control system based on an electronic control air suspension and an electronic control brake system. According to the system, the passenger car rollover risk is predicted according to the running state of a passenger car, when it is monitored that the rollover risk of the passenger car is about to happen, the system warns a driver through a buzzer and an alarm indicator lamp, the air inlet an exhaust states of air springs for connecting the passenger car body and the left and right sides of an axle are adjusted in time, and the passenger car outer suspension rigidity is improved; meanwhile, by adjusting the vertical load distribution between wheels again, vertical loads on the brake wheel are increased, the system can apply sufficient brake torque through a differential brake method, and the phenomenon that the brake wheel is locked or the wheel brake force is not sufficient during braking is avoided. The system can adopts an existing electronic control air suspension and the brake system of the passenger car, rollover control over the passenger car can be effectively achieved in a coordinated control mode of the suspension system and the brake system, the passenger car anti-rollover performance is improved, the passenger car rollover accident occurrence rate is lowered, and the control algorithm is convenient to transplant.

Description

technical field [0001] The invention belongs to the technical field of automobile active safety, and in particular relates to an anti-rollover control system and an anti-rollover control method for a passenger car based on an electronically controlled air suspension and an electronically controlled braking system. Background technique [0002] With the rapid development of road transportation facilities, the output and quality of passenger cars have been qualitatively improved. The improvement of the convenience and comfort of road passenger transport has also prompted more and more people to choose road passenger transport. However, due to the characteristics of longer length, higher center of mass, and large vertical load changes, passenger cars are more prone to rollover and instability, and Rollover accidents are mostly heavy and extraordinarily serious traffic accidents, with many casualties and high accident severity. Electronically Controlled Air Suspension (ECAS for...
