Abstract
Vehicle movement in an automatic driving operation is regulated in an automatic driving operation, which is switchable between a regular operating mode and an emergency operating mode when a functional impairment of a main control device is established. In the regular operating mode, the regular desired trajectory, the emergency operation desired trajectory, and the lane course of a driving lane driven along by the vehicle are continuously determined in a coordinate system, fixed to the vehicle, of the main control device. The determined emergency operation desired trajectory and the determined lane course are supplied to the ancillary control device and stored there. In the emergency operating mode, the lane course of the driving lane driven along by the vehicle is determined in a coordinate system, fixed to the vehicle, of the ancillary control device. In the emergency operating mode, based on the lane course stored in the ancillary control device and the lane course stored in the ancillary control device, an angle error between the coordinate systems of the main control device and the ancillary control device is determined and its influence on the regulation carried out by the ancillary control device is compensated for.
