摘要： A vehicle attitude control apparatus, wherein a corrected behavior index value for steering is determined in such a manner that the deviation between a target behavior index value for a vehicle and a corrected behavior index value for steering decreases, as an instability index value correlating to the amount of under-steer increases, and when the target behavior index value and the behavior index value are equal, the corrected behavior index value for steering is set to equal the behavior index value. A corrected behavior index value for braking is determined in such a manner that the deviation between the target behavior index value and a corrected behavior index value for braking increases, as the instability index value increases, and when the target behavior index value and the behavior index value are equal, the corrected behavior index value for braking is set to equal the behavior index value. The steering actuator and braking forces are controlled in such a manner that, when not in the state of under-steer, the behavior index value follows the target behavior index value, and when in the state of under-steer, the corrected behavior index value for steering and corrected behavior index value for braking follow the target behavior index value.

摘要： In a vehicle attitude control apparatus, a steering actuator is controlled so that a steering angle matches a target steering angle. In an understeer condition; the braking force on the inside wheels is increased and drive power applied to the outside wheels is larger than applied to inside wheels. In an oversteer condition, the braking force on the outside wheels is increased and drive power applied to the inside wheels is larger than applied to outside wheels. The steering actuator is controlled so that a behavior index value corresponding to the change in the vehicle'behavior, that occurs based on the change in the steering angle, matches a target behavior index value that reflects the amount of operation of an operation member. A vehicle yaw moment and an amount of control of the steering actuator vary due to steer conditions, wheel lateral slip angle and brake force control.

摘要： The steering device is constructed by supporting a center portion of a rectangle-plate-shaped operation plate at one end of a supporting shaft projected from the front face of a dashboard so as to freely swing in right and left directions. A steering apparatus for a vehicle having the steering device detects the swing direction and the swing angle of the operation plate with a steering angle sensor provided at a support portion and moves a steering mechanism in the detected direction in accordance with the detected angle so as to steer the vehicle. With this structure, a load in steering can be decreased and tiredness in driving can be reduced. Furthermore, such a steering apparatus can realize a steering device which physically handicapped drivers can operate easily.
