    摘要： In accordance with a steering apparatus (20), a grip state between a ground surface on which a steered wheel is grounded and the steered wheel is estimated by a grip degree estimation arithmetically operating process (30a) which is arithmetically operated by AFS_ECU (30), and VGRS target angle is set such that a steering gear ratio is increased in the case that the grip degree gets close to a grip limit on the basis of an estimated grip state, in accordance with a grip degree vs gear ratio map (30b). Accordingly, since it is possible to estimate the grip degree which is changed in correspondence to a magnitude of the road surface it, for example, in the case that the steered wheel gets close to the grip limit, it is possible to increase the steering gear ratio so as to set large even at a time when the vehicle runs at the low speed. Therefore, since it is possible to prevent a phenomenon that the steered wheel is largely controlled by a smaller steering angle from being generated in the case that the vehicle runs on the road surface having the low μ, there is obtained an effect that a stability in the vehicle motion can be improved.

    摘要： In accordance with a vehicle motion control apparatus, a steering angle (θh) of a steering wheel is determined on the basis of a rotation angle (θpm) of an assist motor (24m) detected by a rotation angle sensor (24s) and a rotation angle (θvm) of a gear ratio variable motor (32m) detected by a rotation angle sensor (32s), and a VGRS control process (40a) of a gear ratio variable mechanism is executed on the basis of the determined steering angle (θh). Accordingly, since the steering angle (θh) of the steering wheel is determined on the basis of the rotation angle (θvm) used for the VGRS control process (40a) of the gear ratio variable mechanism and the rotation angle (θpm) used for an EPS control process (30a) of an EPS actuator, it is possible to obtain the steering angle (θh) of the steering wheel without a steering angle sensor. Therefore, it is possible to reduce the number of the parts of a vehicle motion control apparatus.

    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).

    摘要： A steering control apparatus obtains a steered amount by which a steered wheel is steered based on a left-and-right braking force difference control amount, a vehicle state control amount, and a steering control amount. The apparatus changes the magnitude of the braking force difference control amount and the magnitude of the vehicle state control amount according to a vehicle speed or to time elapsed from when braking started to be applied to the left and right wheels. Accordingly, the vehicle driving on a μ-split road is prevented from being deflected toward a side of higher friction coefficient due to the left-and-right braking force difference when the braking is applied.
