Steering force control system

摘要

A steering force control system includes a steering means for changing directions of pair of left and right wheels in response to control by a driver of a vehicle, a steering toque detection means for detecting a steering torque when the steering means is controlled, a steering assist means for applying a steering assisting force to the control of the steering means, wheel speed detection means for detecting wheel speeds of the pair of left and right wheels. An additional torque calculation means calculates an additional torque which is sufficient to suppress an occurrence of a steering wheel pulling phenomenon when a limited slip differential gear for applying an inhibiting torque which is a differential limiting force between the pair of left and right wheels is actuated through proportional control and integration control of a steering torque detected by the steering torque sensor and a basic assisting torque which is determined based on a steering assisting force control performed by the steering assist means. A steering assist control means controls the steering assist means so that an additional torque calculated by the additional torque calculation means refers to the steering assisting force.
