    摘要： In a steering apparatus, in accordance with a grip limit control process (30b′), it is determined whether or not a grip degree ε estimated by a grip degree estimation arithmetically operating process (30a) is less than a predetermined grip degree (ε′), and in the case that it is determined that an estimated grip degree (ε) is less than the predetermined grip degree (ε′), the process applies such a feeling that a steering operation by a steering wheel suddenly becomes light to a driver, by suddenly increasing an assist quantity by a motor (M), thereby notifying the driver of the matter that the grip degree of a steered wheel is close to a limit. Therefore, it is possible to transmit to the driver a probability that a side slip is generated by further turning the steering wheel 21 in the same direction as the current direction, thereby calling the driver's attention for steering. Accordingly, there is an effect that a stability of a vehicle behavior can be improved without applying any fear of insecurity to the driver.

    摘要： In accordance with a vehicle motion control apparatus, a steering wheel torque (Th) generated in accordance with an operation of a steering wheel is determined in accordance with a steering wheel torque arithmetic process (30b) by EPS_ECU by using a steering torque (Tp) generated in a second steering shaft of a gear ratio variable mechanism, a motor torque (Tvm) generated by a motor (32m) of the gear ratio variable mechanism and a rotation angle (θvm) of the motor (32m), on the basis of a dynamic equation expressing a torque transfer by the gear ratio variable mechanic Accordingly, even in the case that the vehicle motion control apparatus employs a structure that the gear ratio variable mechanism is interposed between the steering wheel and a torque sensor, the steering wheel torque (Th) can be known without adding any new torque sensor or the like. Therefore, it is possible to improve a motion controllability of the vehicle without increasing a number of parts by using the steering wheel torque (Th) for an ESP control process (30a).
