Abstract
A control method of the toe and camber angles of rear active suspensions of a vehicle; the control method includes the steps of: detecting when the vehicle follows a curved trajectory; conferring negative toe angles combined with zero camber angles to the rear active suspensions, when starting the curved trajectory and when the vehicle enters the curved trajectory; and conferring positive camber angles combined with negative toe angles to the rear active suspensions, while following the curved trajectory and when the vehicle is inscribed in the curved trajectory.
Claims10
A control method of the toe and camber angles of rear active suspensions of a vehicle;
- each rear active suspension comprises a first actuator drivable to vary the camber angle of the rear active suspension and a second actuator drivable to vary the toe angle of the suspension;
- the control method comprises the steps of:
- detecting when the vehicle follows a curved trajectory;
- conferring, by respectively activating the second actuators and the first actuators, negative toe angles combined with zero camber angles to both the rear active suspensions, when starting the curved trajectory and when the vehicle enters the curved trajectory;
- and
- conferring, by respectively activating the second actuators and the first actuators, positive toe angles combined with negative camber angles to both the rear active suspensions, while following the curved trajectory and when the vehicle is inscribed in the curved trajectory.
