Abstract

A method and a device for handing over a motor vehicle to the driver during an automatic parking space-leaving maneuver performed by an automatic parking function. The method includes receiving an external parking space-leaving signal reflecting the driver's wish to get the motor vehicle out of the parking space, initializing the parking space-leaving maneuver and supplying an operating voltage to all vehicle components as a result of the reception of the parking space-leaving signal, carrying out the parking space-leaving maneuver from a parked position into a target position, switching off the voltage supply to predetermined vehicle components once the target position has been reached; and connecting the voltage supply to all vehicle components when the driver performs predetermined actions upon getting into the vehicle in the target position.

First claim

The invention claimed is:

1. A method for handing over control of a motor vehicle to the driver during an automatic parking space-leaving maneuver performed by an automatic parking function, the method comprising:
receiving an external parking space-leaving signal indicating the driver's desire for the motor vehicle to leave the parking space and, in response to the parking space-leaving signal:
automatically initializing the parking space-leaving maneuver and supplying all vehicle components with operating voltage in response to the reception of the parking space-leaving signal;
automatically carrying out the parking space-leaving maneuver from a parked position into a target position;
automatically switching off the voltage supply to predetermined vehicle components in response to the target position having been reached, wherein the method further comprises

connecting the voltage supply to all vehicle components in response to the driver performing predetermined actions after entering the vehicle while the vehicle is positioned at the target position.

2. The method of claim 1 , wherein the predetermined actions comprise an actuation of the brake and/or an actuation of the engine starter.

3. The method of claim 1 , wherein the vehicle components to be supplied with operating voltage are subdivided into first and second vehicle components, wherein the first vehicle components comprise at least the information units for informing the driver about safety-relevant states of the vehicle components, and the second vehicle components comprise at least the drive controller.

4. The method of claim 1 , wherein switching off the voltage supply to predetermined vehicle components switches off voltage to information units for informing the driver about safety-relevant states of the vehicle components, and maintaining operating voltage to the drive controller when the target position has been reached, wherein the target position is a predefined position.

5. A device for handing over control of a motor vehicle to the driver during an automatic parking space-leaving maneuver by an automatic parking function, wherein the device receives an external parking space-leaving signal indicating the driver's desire for the motor vehicle to leave the parking space, and in response to such receipt, automatically initializes the parking space-leaving maneuver and automatically supplies all vehicle components with operating voltage in response to the reception of the parking space-leaving signal, automatically carries out the parking space-leaving maneuver from a parked position into a predetermined target position, and, in response to reaching the predetermined target position, automatically switches off the voltage supply to predetermined vehicle components once the target position has been reached, wherein the device automatically connects the voltage supply to all vehicle components in response to the driver performing predetermined actions after entering the vehicle in the target position, wherein the device comprises a unit for performing the automatic parking function, first vehicle components comprising at least the information units for informing the driver about safety-relevant states of the vehicle components, second vehicle components comprising at least the drive controller, a remote control for remotely controlling the automatic parking function, and a control unit for communication with the remote control, and
wherein the device has a unit for switching the supply of the vehicle components with operating voltage, wherein the unit for switching the operating voltage can switch the supply of the first vehicle components on and off while maintaining the voltage supply of the second vehicle components.

6. The device of claim 5 , wherein the unit for switching the operating voltage is controlled by the control unit.

7. The device of claim 5 , wherein the unit for switching the operating voltage is a relay circuit.

8. The device of claim 5 , wherein the communication of the vehicle components among one another and with the control unit is effected via (Controller Area Network) CAN busses, wherein the CAN busses are connected to one another via a gateway.

9. The device of claim 5 , wherein the control unit is a body control module.

10. The device of claim 5 , wherein the unit for switching the operating voltage switches the supply of the first vehicle components on and off while maintaining the voltage supply of the second vehicle components in response to the motor vehicle reaching the predetermined target position.
