Abstract

A method and a device are provided for distance regulation of a motor vehicle equipped with an object detection sensor which detects objects located in front and regulates the velocity of the host vehicle in the sense of distance regulation, the distance control system being able to brake the host vehicle to a standstill. If objects are no longer detected during the stopping process due to the fact that they are located within the invisible region in the immediate vicinity of the object detection sensor, object positions relating to the objects detected earlier are stored, and a starting process of the vehicle resulting from the driver'"'"'s intention to start, implemented via an actuation and/or confirmation element, is prevented until the object is detected again. The restarting process is not prevented when a turning maneuver of the object located in front has been detected due to the fact that the absolute value of the transverse offset of the object located in front exceeds a predetermined threshold value.

Claims

1-11. -11. (canceled)

12. A device for distance regulation of a host vehicle comprising:

an object detection sensor configured to detect at least one object located in front and regulate a velocity of the host vehicle in a sense of distance regulation; and

a distance controller configured to brake the host vehicle to a standstill;

wherein an object position relating to the at least one detected object which is no longer detected during a stopping process is stored, and a starting process of the vehicle is prevented until the object is detected again.

13. The device according to claim 12, wherein the object is no longer detected because it is located within an invisible region in an immediate vicinity of the object detection sensor.

14. The device according to claim 12, wherein the object position is stored by carrying out a tracking of a trajectory of the object located in front.

15. The device according to claim 12, wherein a starting process is not reactivated until the object is at a sufficient distance from the object detection sensor.

16. The device according to claim 12, wherein the vehicle is not started again until a driver activates at least one of an actuating and a confirmation element via which a driver'"'"'s intention to start is signaled.

17. The device according to claim 12, wherein a transverse offset of the object located in front is determined by the object detection sensor.

18. The device according to claim 12, wherein a turning maneuver is detected when an absolute value of a transverse offset of the object located in front exceeds a predetermined threshold value.

19. The device according to claim 12, wherein a restarting process is not prevented when a turning maneuver of the object located in front has been detected.

20. The device according to claim 12, wherein tracking and turn detection are also carried out when the distance regulation is deactivated, so that current object data are already present when the distance controller is activated.

21. The device according to claim 12, further comprising:

a warning device configured to communicate to a driver that a start is not possible on account of being currently prevented by the distance controller.

22. A method for distance regulation of a host vehicle, the method comprising:

detecting at least one object located in front by an object detection sensor;

regulating a velocity of the host vehicle in a sense of distance regulation;

braking the host vehicle to a standstill by a distance controller;

storing an object position relating to the at least one detected object which is no longer detected during a stopping process; and

preventing a starting process of the vehicle until the object is detected again.
