Detection of unintended lane departures
First Claim
1. A method of automatically detecting unintended roadway lane departures of a moving vehicle, comprising:
- monitoring the occurrence of actual or forthcoming lane departures by the vehicle;
monitoring one or more vehicle-related parameters that may change continuously in response to a control intervention or activity of a driver; and
generating an alarm signal if a) an actual or forthcoming lane departure is detected and b) if an evaluation of the one or more parameters indicates low or no driver activity.

Abstract
A method and a system for automatically detecting unintended lane departures of vehicles arc described. A lane departure warning system comprises a lane departure recognition unit (10), an alarm generation unit (12), and a driver activity monitoring unit (14). The driver activity monitoring unit (14) is configured to monitor one or more vehicle-related parameters like the steer angle that change continuously in response to a control intervention of a driver. The alarm generation unit (12) generates an alarm if an actual or forthcoming lane departure is detected and if additionally an evaluation of the one or more parameters indicates a low or no driver activity.
