Method for adjusting the spatial position of the roll axis of a motor vehicle
First Claim
1. A method for shifting a spatial position of a roll axis of a motor vehicle from a first spatial position extending through a longitudinal center of the motor vehicle when the motor vehicle travels along a first trajectory having a first radius of curvature to a desired second spatial position transversely offset from the first spatial position, the method comprising:
- determining with a sensor installed in the motor vehicle a transverse acceleration of the motor vehicle and adjusting with a controller of the motor vehicle at least one first actuator of an active suspension system of the motor vehicle, so that the motor vehicle assumes a transverse tilt with respect to a road surface about the first roll axis disposed in the spatial first position while travelling along the first trajectory; and
adjusting with the controller of the motor vehicle at least one second actuator which influences by way of a steering intervention a transverse movement of the motor vehicle, causing the motor vehicle to travel along a second trajectory having a desired transverse offset from the first trajectory, and adjusting with the at least one first actuator the desired transverse tilt,with the adjusted desired transverse tilt in conjunction with the desired transverse offset shifting the roll axis from the first spatial position to the desired second spatial position,wherein the method is performed in conjunction with fully automated vehicle guidance.

Abstract
A method for adjusting the spatial position of the roll axis of a motor vehicle includes: a) defining a desired spatial position of the roll axis; b) determining a transverse acceleration of the motor vehicle; c) defining a desired transverse tilt of the motor vehicle and determining a desired transverse offset of the motor vehicle as a function of the transverse acceleration, so that the roll axis is moved into the desired position when the desired transverse tilt and the desired transverse offset are adjusted; d) adjusting a first actuator of an active chassis system of the motor vehicle, so that the motor vehicle assumes the desired transverse tilt determined in step c); and adjusting a second actuator to influence the transverse movement of the motor vehicle, so that the motor vehicle assumes the desired transverse offset determined in step c).
