Abstract

A motor vehicle has a drive device, a control device for starting and turning off the drive device and a detection device for monitoring the presence of a person in the motor vehicle. The control device is designed to turn off the drive device if the detection device signals that the person leaves or has left the motor vehicle. The control device is also set up to restart the drive device, after it has been previously detected that the person has gotten out of the motor vehicle, if the detection device signals the presence of a person again.

Claims

1-9. -9. (canceled)

10. A method for controlling a drive device in a motor vehicle using a control device, comprising:

starting by the control device, the drive device if it is detected that a starting device has been operated by a driver;

monitoring by a detection device, whether the driver is present in a predetermined monitoring area of the motor vehicle and whether the driver has left the motor vehicle;

automatically turning off, by the control device, the drive device;

monitoring, by the detection device, whether the driver again becomes present in the predetermined monitoring area; and

restarting, by the control device, the drive device if the detection device signals that the driver is again present in the predetermined monitoring area, wherein

monitoring is terminated if a vehicle door has been locked after the driver has left the motor vehicle.

11. The method as claimed in claim 10, wherein the control device turns off the drive device if the motor vehicle stops moving.

12. The method as claimed in claim 10, wherein

the control device turns off the drive device while allowing electrical loads to continue to be operated, and

the electrical loads are turned off when monitoring is terminated.

13. The method as claimed in claim 10, wherein

the control device turns off the drive device if the motor vehicle stops moving, while allowing electrical loads to continue to be operated, and

the electrical loads are turned off if the detection device detects that the driver has left the motor vehicle.

14. The method as claimed in claim 13, wherein the control device restarts the drive device and the electrical loads when the detection device signals that the driver is again present in the predetermined monitoring area.

15. The method as claimed in claim 10, wherein

if the driver operates a stop device, the drive device is manually turned off, and

the control device restarts the drive device only if the drive device was automatically turned off.

16. The method as claimed in claim 10, wherein

an identity check is performed on a person in a vicinity of the motor vehicle, and

if the person becomes present in the predetermined monitoring area, the vehicle is restarted only if the person is authorized to use the motor vehicle.

17. The method as claimed in claim 10, wherein the control device restarts the drive device after:

the detection device signals that the driver is again present in the predetermined monitoring area, and

the driver has pressed a pedal of the motor vehicle.

18. The method as claimed in claim 10, wherein the drive device is restarted if:

it is detected that the driver is again present in the predetermined monitoring area, or

a predetermined operating device of the motor vehicle, which is different from the starting device, has been operated.

19. The method as claimed in claim 18, wherein the predetermined operating device is a device selected from the group consisting of a gas pedal, a brake pedal, a clutch pedal, a steering wheel, a vehicle door, a seat belt and a seat belt buckle.

20. The method as claimed in claim 10, wherein the detection device monitors a signal from at least one device selected from the group consisting of:

a sensor in a vehicle seat,

a locating device for locating an identification chip of a keyless-go system,

a sensor in a pedal or a seat belt,

a sensor in a vehicle door, and

an alarm system.

21. The method as claimed in claim 10, wherein if the detection device detects that the driver has left the motor vehicle and the drive device is turned off, monitoring whether the driver again becomes present is carried out only for a predetermined interval of time after the drive device has been turned off.

22. The method as claimed in claim 21, wherein

the control device turns off the drive device while allowing electrical loads to continue to be operated, and

the electrical loads are turned off when monitoring is terminated.

23. The method as claimed in claim 10, wherein the drive device is restarted if the detection device detects actuation of a vehicle component selected from the group consisting of a gas pedal, a brake pedal, a clutch pedal, a steering wheel, a vehicle door, a seat belt and a seat belt buckle.

24. The method as claimed in claim 10, wherein

the control device turns off the drive device if the motor vehicle stops moving, and

the drive device is restarted if the detection device detects actuation of a vehicle component selected from the group consisting of a gas pedal, a brake pedal, a clutch pedal, a steering wheel, a vehicle door, a seat belt and a seat belt buckle.

25. A method for controlling a drive device in a motor vehicle using a control device, comprising:

starting by the control device, the drive device if it is detected that a starting device has been operated by a driver;

monitoring by a detection device, whether the driver is present in a predetermined monitoring area of the motor vehicle and whether the driver has left the motor vehicle;

automatically turning off, by the control device, the drive device;

monitoring, by the detection device, whether the driver again becomes present in the predetermined monitoring area; and

restarting, by the control device, the drive device if the detection device signals that the driver is again present in the predetermined monitoring area, wherein

an identity check is performed on a person in a vicinity of the motor vehicle, and

if the person becomes present in the predetermined monitoring area, the drive device is restarted only if the person is authorized to use the motor vehicle.

26. The method as claimed in claim 25, wherein the drive device is restarted if:

it is detected that the driver is again present in the predetermined monitoring area, or

a predetermined operating device of the motor vehicle, which is different from the starting device, has been operated.

27. The method as claimed in claim 25, wherein if the detection device detects that the driver has left the motor vehicle and the drive device is turned off, monitoring whether the driver again becomes present is carried out only for a predetermined interval of time after the drive device has been turned off.

28. A motor vehicle comprising:

a drive device;

a detection device to monitor whether a person is present in a predetermined monitoring area of the motor vehicle; and

a control device to;

start the drive device if it is detected that a starting device has been operated by a driver;

turn off the drive device if the detection device detects that the driver has gotten out of the motor vehicle;

restart the drive device, after it has been detected that the driver has gotten out of the motor vehicle, if the detection device signals that the driver is again present in the predetermined monitoring area, wherein

the detection device stops monitoring whether a person is present in the predetermined monitoring area if a vehicle door has been locked after the driver has left the motor vehicle.

29. A motor vehicle comprising:

a drive device;

a detection device to monitor whether a person is present in a predetermined monitoring area of the motor vehicle; and

a control device to;

start the drive device if it is detected that a starting device has been operated by a driver;

turn off the drive device if the detection device detects that the driver has gotten out of the motor vehicle;

restart the drive device, after it has been detected that the driver has gotten out of the motor vehicle, if the detection device signals that the driver is again present in the predetermined monitoring area, wherein

an identity check is performed before restarting the drive device, and

the drive device is restarted only if the identity check shows that an authorized user is present in the predetermined monitoring area.
