摘要： A control unit estimates reverse transfer torque transferred from tires to a steering wheel and calculates an assist gain based on the reverse transfer torque. The control unit calculates basic assist torque demand by multiplying torsion torque detected by a torque sensor by the assist gain. The control unit further calculates assist torque command by adding compensation for stabilization. Since the assist gain is determined based on the reverse transfer torque, actual assist torque is generated in accordance with the force transferred from the road surface. Thus, a driver can operate the steering wheel while feeling the force from the road surface.

摘要： In a steering system, a generator generates a first commanded value for assist torque, and a converter converts a second commanded value for the assist torque to a commanded current value. A current controller controls a drive current for driving a motor for generating the assist torque. A characteristic limiter is functionally interposed between a commanded-value generator and a converter, and limits, to a preset characteristic range, a characteristic of a functional downstream of the converter in the steering system. The functional downstream of the converter in the steering system includes a steering mechanism including the motor. The commanded-value generator inputs, to the characteristic limiter, the first commanded value. The characteristic limiter determines the second commanded current value for the assist torque based on the characteristic of the functional downstream and the first commanded value.

摘要： In a driving condition control system, a sensing unit senses a first physical quantity indicative of a rotation of the first rotatable axle assembly and a second physical quantity indicative of a rotation of the second rotatable axle assembly. A determining unit compares the first and second physical quantities of the rotations of the first and second rotational axle assemblies and determines whether a driving condition of the vehicle is unstable according to the compared result. As a result, the unstable condition of the vehicle can be rapidly detected without detecting a yaw moment of the vehicle.

摘要： In a power steering apparatus employing an EPS (electrical power steering) motor coupled to a steering mechanism, when vibration of the steering mechanism is produced by twisting of tire rubber due to changes in steering angle, resultant pulsation of the drive current of the EPS motor are suppressed by adding to the drive current a current that is of equal frequency and opposite phase to the pulsation. Vibration of the EPS motor shaft, and resultant vibration of the steering wheel and vehicle body, are thereby effectively suppressed.
