    摘要： An electronic control unit calculates a target yaw rate in accordance with a vehicle speed and a steering angle and calculates the yaw rate difference on the basis of the target yaw rate and an actual yaw rate. The electronic control unit estimates the grip factor of a front wheel to road surface and sets a distribution ratio for distribution of a vehicle-control target value among actuators of a steering system, a brake system, and a drive system in accordance with the estimated grip factor. The electronic control unit controls the actuators of the three systems in accordance with control instruction values distributed on the basis of the vehicle-control target value and the distribution ratio.

    摘要： When a variable value indicates that a steering characteristic is understeer, a control unit controls a variable transmission ratio device to change a second steering angle such that the greater the understeer indicated by the variable value, the smaller the steering angle of steered wheels relative to the turning angle of a steering wheel becomes. When the differentiated value of the variable value indicates that the understeer is changing to increase, a correction unit corrects the variable value such that the greater the degree of change of the understeer indicated by the differentiated value, the greater the understeer indicated by the variable value becomes. Hence, the attitude of a vehicle in understeer is stabilized with a simple configuration.

    摘要： This invention provides a vehicle motion control method and a vehicle motion control apparatus capable of improving the behavior stability of a vehicle. According to the vehicle motion control method, vehicle steering characteristic is determined based on a behavior amount differentiated value obtained by differentiating (S203) a slip angle differential value which is a behavior amount of the vehicle which occurs around a z-axis in the vertical direction with respect to the vehicle body (S205, S209). Consequently, because the phase of the slip angle differential value is progressed, the transition tendency of the steering characteristic, that is, which the vehicle motion condition is moved to over-steer or under-steer, can be obtained early. Therefore, the starting timing of the steering control or drive power control of the vehicle can be accelerated thereby improving the behavior stability of the vehicle.
