Abstract:
1. A method for affecting a cornering performance of a motor vehicle, the method comprising the steps of: a) determining a transverse acceleration of the motor vehicle based on a signal received from at least one sensor installed on the motor vehicle; b) defining a desired transverse tilt of the motor vehicle as a function of the transverse acceleration determined at step a); c) adjusting with an Active Body Control (ABC) device at least one actuator of an active suspension system of the motor vehicle, so that the motor vehicle assumes the desired transverse tilt determined at step b); and d) adjusting with the Active Body Control (ABC) device at least one additional actuator, which intervenes in a steering system of the motor vehicle, by superimposing on a first steering angle used for steering the motor vehicle a superimposed steering angle to produce a combined steering angle so that a radius of curvature of a trajectory of the motor vehicle, when steered with the combined steering angle, corresponds substantially to the radius of curvature of the trajectory of the motor vehicle that would have resulted when the motor vehicle was steered with the first steering angle, thereby at least partially compensating a yaw movement of the motor vehicle caused by the adjustment of the at least one actuator of the active suspension system, wherein a suitable superimposed steering angle is predefined for all possible actively adjustable values of the desired transverse tilt, wherein at step a) a future transverse acceleration of the motor vehicle is determined by a device for automatic roadway preview, and wherein at step b) the desired transverse tilt of the motor vehicle is determined by the device for automatic roadway preview.
