Abstract
A method of alerting the driver of a vehicle to a lane departure condition. The method includes operating a lane detection system to detect that the vehicle is experiencing a lane departure condition, operating a sensor to detect background vibration experienced by the vehicle, determining a characteristic making a haptic signal likely to be distinguishable from the background vibration, and operating a haptic signal generator in response to the lane departure condition to deliver to a driver the haptic signal having the characteristic.
