MOTION CONTROL DEVICE OF VEHICLE

摘要

PROBLEM TO BE SOLVED: To suitably stabilize behavior of a vehicle when oversteer is caused, to restrain exertion of a sense of incongruity on a driver in a limit area of the oversteer, and to enhance convergence of control when finishing braking force control, in a motion control device for controlling motion of the vehicle in turning operation by combining steering angle control and braking force control.

SOLUTION: This motion control device of the vehicle includes a steering control ECU 20 for controlling a steering angle of dirigible road wheels FL and FR so that an actual turning control quantity becomes a target turning control quantity, and a braking and engine control ECU 30 for controlling vehicle braking force so that the actual tuning control quantity becomes the target turning control quantity. In the motion control device of the vehicle, control of the steering control ECU is stopped based on the fact of detecting the timing for starting braking force control when the braking and engine control ECU detects an oversteer state of the vehicle.
