Abstract
In a vehicle motion control system, a target rear-wheel steering-angle calculating section calculates a target rear-wheel steering angle, a rear-wheel steering-quantity setting section sets a rear-wheel steering quantity, and a rear-wheel steering signal output section outputs a rear-wheel steering quantity to a motor driving section to perform a steering angle control. In addition, a front-and-rear wheel steering response-parameter calculating section calculates a response parameter, and a front-and-rear wheel steering target yaw-rate calculating section calculates a target yaw rate. A yaw-rate difference calculating section calculates a yaw-rate difference, a target braking-force calculating section calculates a target braking force, and a braked-wheel discriminating section selects a wheel to be braked. When an output discriminating section determines that there is within a controllable region, a braking signal output section outputs a signal to a brake driving section so as to add the target braking force to the selected wheel.
