Modeling and Analysis of the Proportional Control Four-Wheel Steering Vehicle Handling and Stability

Abstract:

Four-wheel steering (4ws) refers to the meaning of besides usually turn the front wheels of the vehicle, plus the corresponding rear wheel steering. Its main purpose is to increase the vehicle steering stability at high speed or in lateral force under the action , improve the vehicle steering portability at low speed and turning radius at high speed.A 4ws vehicle dynamic model with two-degree of freedom^[1,2] was established, and presents the corresponding dynamic equation. Using the theory of vehicle handling dynamics,according to the 4ws vehicle dynamic equation,the transient response of 4ws vehicle steering are detailed analyzed.Compared with 2ws steering, illustrates the manipulation of 4ws vehicle has strong handling stability.
