摘要： Motor vehicle steering system for driving a steering mechanism (1) on the basis of an operation angle (δ h ) of an operation mechanism (2). The system includes: a behavioral variable computation section (4A) for performing computation on a behavioral variable indicative of a behavior of a motor vehicle; and a steering angle controlling section (4B) for sequentially updating a relationship between a steering angle (δ f ) of vehicle wheels (10) and the operation angle (δ h ) of the operation mechanism (2) on the basis of a value of the behavioral variable computed by the behavioral variable computation section (4A) and a preset target value of the behavioral variable and controlling the steering mechanism (1) 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 (δ f ) of the vehicle wheels (10) to the operation angle (δ h ) of the operation mechanism (2). The behavioral variable may be a time constant indicative of a responsiveness of a change in the steering angle (δ f ) of the vehicle wheels (10) to a change in the operation angle (δ h ) of the operation mechanism (2).

摘要： The present invention provides an electric power steering device (1) enabled to compensate for the influence of the inertia of a steering-assisting-force generating motor (10) on steering with accurate timing even when a steering direction is reversed at high speed. Based on steering torque (T) and a rotation angular speed (ω) of a steering-assisting-force generating motor (10), a steering angular acceleration correspondence value (du/dt) is obtained. The device has means (20d) for regulating a gain (Kg), which is multiplied to a change acceleration (dT/dt) of the steering torque (T). The motor (10) is controlled so that the steering assisting force (I*) is corrected according to a motor output correction value (Ic) obtained on the basis of the relation between the motor output correction value (Ic) and the steering angular acceleration correspondence value (du/dt), which is preliminarily determined and stored in such a way as to compensate for the influence of the inertia on steering, and the obtained steering angular acceleration correspondence value (du/dt).
