    • A motor-driven power steering controller (ECU1) for a vehicle comprises a steering torque controlling unit (B0) for controlling a steering torque on a steering wheel (1) depending on a steering operation of the vehicle to reduce an operator's power required to operate the steering wheel (1), a braking force estimating unit (B1) for estimating braking forces to be imposed on wheels of the vehicle and a right and left braking force difference estimating unit (B2) for estimating difference between the braking forces to be imposed on the right and left wheels each estimated by the braking forces estimating unit. The controller further comprises an assist steering torque providing unit (B3) for adding a counter-steering assist steering torque assisting an operator's counter-steering operation on the steering wheel to the steering torque controlled by the steering torque controlling unit (B0) in the counter-steering direction on the basis of the difference in braking force between right and left wheels estimated by the right and left brake force difference estimate unit (B2), wherein the assist steering torque providing unit is arranged so as to inhibit provision of the assist steering torque when the stability of the vehicle is controlled by the vehicle stability controlling unit.
    • 用于车辆的电动机动力转向控制器(ECU1)包括:转向转矩控制单元(B0),用于根据车辆的转向操作来控制方向盘(1)上的转向转矩,以减少操作者操作所需的动力 方向盘(1),用于估计要施加在车辆的车轮上的制动力的制动力估计单元(B1)和用于估计要施加的制动力之间的差异的左右制动力差估计单元(B2) 在由制动力估计单元估计的左右车轮上。 所述控制器还包括辅助转向转矩提供单元(B3),用于将辅助操舵方向盘上的操作者对舵操作的反向转向辅助转向扭矩与由所述转向转矩控制单元(B0)控制的转向转矩相加 基于由右和左制动力差估计单元(B2)估计的左右车轮之间的制动力的差异的导向方向,其中辅助转向转矩提供单元布置成禁止提供辅助转向 车辆的稳定性由车辆稳定性控制单元控制时的转矩。
