Abstract
A method for controlling a motor vehicle includes detecting a first predefined trajectory, determining a region across which the first trajectory leads, determining a second trajectory that has a different extension in the determined region than the first trajectory, detecting a driver-controlled selection of one of the trajectories, and autonomously controlling the motor vehicle in such a way that it follows the selected trajectory.
Claims10
A method for autonomously controlling a motor vehicle in a parking or unparking operation, the method comprising:
- storing, via a memory, a first trajectory;
- determining, via a processor, at least one region across each of which the first trajectory leads;
- determining, via the processor, at least one second trajectory that has a different extension than the first trajectory in the at least one determined region;
- displaying, via an output device, the first trajectory and the at least one second trajectory;
- detecting, via an input device, a driver-controlled selection of one of the trajectories displayed via the output device;
- autonomously controlling, via the processor, the motor vehicle to follow the selected trajectory;
- determining, during an autonomous guidance of the motor vehicle, whether an error state is present, wherein the error state is caused by the driver failing to operate the control element for longer than a predefined time;
- and wherein the error state is caused by a distance between the motor vehicle and an object being less than a threshold value;
- and
- placing, if there is the error state, the motor vehicle in a safe state requiring a standstill of the motor vehicle;
- wherein the autonomous controlling of the vehicle takes place at a velocity of the parking and/or unparking operation, and
- wherein the safe state requires a standstill of motor vehicle in which a service brake or a parking brake is activated to bring the motor vehicle to the standstill.
