Abstract
A vehicle includes a first actuating system having an automatic steering actuator to bring the front wheel steer angle to a calculated target front wheel steer angle for lane keeping, and a second actuating system such as a front and rear roll stiffness distribution control system, a front and rear driving force distribution control system, a rear wheel steering system, and a differential limiting force control system. By controlling the second actuating system in accordance with the automatic steering operation, a control unit adjusts the steering characteristic of the vehicle in a direction to improve the yawing response or in a direction to improve the running stability.
