1. A vehicle behavior control system for a vehicle including a pair of front wheels configured to be steered by a vehicle operator and a pair of rear wheels configured to be steered by a steering actuator, comprising:

  • a wheel suspension system supporting each wheel, the wheel suspension system including a variable wheel suspension element that can change an effective stiffness of the corresponding wheel suspension system;

    a first sensor for detecting an operating condition of the vehicle;

    a second sensor for detecting an increase in a road contact load of each rear wheel; and

    a control unit that actuates the steering actuator according to an operating condition of the vehicle detected by the first sensor;

    wherein the control unit is configured to reduce the effective stiffness of the variable wheel suspension element corresponding to at least one of the rear wheels in relation to the effective stiffness of the variable wheel suspension elements corresponding to the front wheels when the second sensor has detected an increase in the road contact load of one of the rear wheels.
