Abstract

A method for detecting a lane change by a moving vehicle is disclosed. In one embodiment, it is detected that a first heading of a moving vehicle has met a parameter defining a stable heading. It is then detected that a second heading of the moving vehicle has subsequently met a parameter defining an unstable heading. It is then detected that a third heading of the moving vehicle has subsequently met a parameter defining a stable heading within a pre-determined time parameter and that the third heading equals the first heading within a pre-defined margin. An indication is then generated that the moving vehicle has performed a lane change.

First claim

What is claimed is:

1. A method for detecting a lane change by a moving vehicle, performed by a computer processor said method comprising:
detecting that a first heading of a moving vehicle has met a parameter defining a stable heading;
storing a plurality of previously determined headings of said moving vehicle;
detecting that a second heading of said moving vehicle has subsequently met a parameter defining an unstable heading by:
determining a deviation in said first headin…
