Abstract
Motor vehicle steering system for driving a steering mechanism on the basis of an operation angle of an operation mechanism. The system includes: a behavioral variable computation section for performing computation on a behavioral variable indicative of a behavior of a motor vehicle; and a steering angle controlling section for sequentially updating a relationship between a steering angle of vehicle wheels and the operation angle of the operation mechanism on the basis of a value of the behavioral variable computed by the behavioral variable computation section and a preset target value of the behavioral variable and controlling the steering mechanism on the basis of the updated relationship. The behavioral variable may be a steady-state gain which is a steady-state ratio of the steering angle of the vehicle wheels to the operation angle of the operation mechanism. The behavioral variable may be a time constant indicative of a responsiveness of a change in the steering angle of the vehicle wheels to a change in the operation angle of the operation mechanism.
