Abstract

A method of determining “true” standstill in a vehicle. The method includes detecting an object outside of the vehicle via a camera, saving first data on the detected object in a memory, detecting the same object after a delay, saving, after the delay, second data on the detected object in a memory, analyzing, by a controller, the first and second data, and determining “true” standstill has occurred based on the analysis.

Claims

1. A method of determining “

true”

standstill in a vehicle, the method comprising;

detecting an object outside of the vehicle via a camera;

saving first data on the detected object in a memory;

detecting the same object after a delay;

saving, after the delay, second data on the detected object in a memory;

analyzing, by a controller, the first and second data;

determining “

true”

standstill has occurred based on the analysis.

2. The method of claim 1, wherein the detecting steps are performed by a camera and the first and second data are images of the detected object.

3. The method of claim 1, wherein the detected object is a stationary object.

4. The method of claim 1, wherein the detected object is a moving object.

5. The method of claim 1, further comprising setting a standstill flag when “

true”

standstill is determined.

6. The method of claim 1, further comprising resetting a standstill flag when the determining “

true”

standstill determines the vehicle is moving.

7. The method of claim 1, further comprising providing an indication of a standstill condition when requested.

8. The method of claim 1, further comprising continuously providing an indication of a standstill condition on a bus in the vehicle.

10. The system of claim 1, wherein the captured objects are a stationary object.

11. The system of claim 1, wherein the captured object is a moving object.

12. The system of claim 1, wherein the controller sets a standstill flag when “

true”

standstill is determined.

13. The system of claim 1, wherein the controller resets a standstill flag when the determining “

true”

standstill determines the vehicle is moving.

14. The system of claim 1, wherein the controller provides an indication of a standstill condition when requested.

15. The system of claim 1, further comprising a bus the controller continuously providing an indication of a standstill condition on the bus.

9. A system for determining a “

true”

standstill condition of a vehicle, the system comprising;

a camera configured to capture an image of objects outside the vehicle; and

a controller configured to

receive images of objects from the camera,

save images received to memory,

compare images saved in memory,

determine from the comparison of the images in the memory if the vehicle is moving, and

provide an indication whether the vehicle is at a “

true”

standstill.
