STEERING APPARATUS FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a vehicular steering apparatus capable of stabilizing vehicle behavior. SOLUTION: The movement of a steering actuator 2 driven according to the operation of an operation member 1 is transmitted to a wheel 4 so as to change its turning angle. This steering apparatus is provided with means 11 and 14 for detecting at least the operation input value of the operation member 1 and a car speed to obtain a variable correlated to vehicle lateral acceleration and a yaw rate, and a means 16 for detecting the yaw rate of the vehicle. A steering system controller 20 controls the steering actuator 2 so as to cancel deviation obtained by subtracting detected lateral acceleration from a target lateral acceleration set according to the variable and deviation obtained by subtracting a detected yaw rate from a target yaw rate set according to the variable.
