Steering angle control device for vehicle

Abstract

Abstract PURPOSE:To decrease the side slipping angle and to reduce the discontinuity of the side deceleration by adding the component responding to the variation speed of the steering wheel operating angle to the steering angle control for both the front and the rear wheels. CONSTITUTION:Hydraulic converting valves 7 and 8 to stroke-control actuators 5 and 6 respectively are controlled electronically by a controller 11. To the controller 11, the signal from a steering angle sensor 12 to detect the operating angle theta of a steering wheel 3, the signal from a car speed sensor 13 to detect the car speed V, the signal from a control steering angle sensor 14 to detect the auxiliary steering angle deltaF of the front wheel through the stroke of an actuator 5, and the signal from a control steering angle sensor 15 to detect the auxiliary steering angle deltaR of the rear wheel through the stroke of an actuator 6 are input. The controller 11 computes the operating angle theta, the front and the rear wheel auxiliary steering angles deltaf and deltar, controls the valves 7 and 8 depending on the deflection with the practical auxiliary steering angles deltaF and deltaR, and makes the steering angles deltaF and deltaR unified to the computed results.
