At the same time, vehicle lateral stability control system can prevent the sudden turn occurrence of vehicles which improves the operational stability of them under limit working conditions.

Vehicle Stability Control Strategy Study and Simulation;

Vehicle stability control can improve handling performance under any situations, and enhance the security at high speed to avoid traffic design and field test validation.

Because the ABS control strategy was developed based on individual wheel model,it is obvious that the ABS control strategy has no the ability to keep the direction stability well in braking.

The result of the simulated indicates that if the slip rate is the object of control in the ABS system,it can greatly improve the direction stability,and also has an important effect on security in the braking.

The fore-body with sharp section angle can produce direction stability at middle-higher angle of attack in the case of side-slip.

In order to evaluate the application safety of shoulder rumble strips,the values of vibration acceleration at the front axle and angular acceleration of steering wheel are adopted as the evaluation parameters of impact condition and directional stability of vehicle.

It used genetic algorithm to solve the eigenvalue problem of asymmetrical interval matrices and quantitatively analyzed the influence of driver on the directional stability from the perspective of system and control theory.

A new vehicle directional stability analysis method was presented based on the research of driver qualification effects on vehicle directional stability by using the eigenvalue problems of unsymmetrical interval matrices.
