Abstract:
A method for actively controlling the balance characteristics of a vehicle includes the following steps: (a) determining an aerodynamic balance, vehicle balance, or both of a vehicle, wherein the vehicle includes a vehicle body, an aerodynamic element coupled to the vehicle body, a rear axle, a front axle, a pair of wheels coupled to the rear axle, a pair of rear wheels coupled to the rear axle, a pair of front wheels coupled to the front axle, an electronic limited slip differential (eLSD) coupled to the rear axle, and the vehicle balance is based on an aerodynamic downforce on the vehicle; (b) determining that there is surplus downforce capacity available based on the vehicle balance; and (c) controlling, by a controller, the eLSD in response to determining that there is surplus downforce capacity available.
