System and method for operating lane departure warning based on rumble strip sensing

Abstract

A lane departure warning (LDW) system that implements a corrective action strategy based on driving conditions for a vehicle is provided. The LDW system comprises a drive unit, first, second, third and fourth wheel speed sensors and a controller. The wheel speed sensors provide a wheel speed signal for a respective first, second, third and fourth vehicle wheel. The controller: receives the wheel speed signals from the respective vehicle wheels, wherein each of the wheel speed signals are indicative of a wheel speed of the respective vehicle wheel; and performs the corrective action strategy based on the determination at least one wheel speed signal satisfies the frequency threshold. The corrective action strategy includes one of: (i) communicating a message to a human machine interface (HMI) in the vehicle indicative of a lane departure event; and (ii) communicating a signal to a steering system to provide a corrective steering input.
