METHOD AND SYSTEM FOR DETECTING A LANE DEPARTURE EVENT

A computer-implemented method and system for detecting a lane departure event are disclosed. The method comprises obtaining a lateral acceleration value of the vehicle; determining a time-to-lane boundary, TTLB, threshold value using a saturated linear function of the lateral acceleration value of the vehicle; determining a current TTLB value of the vehicle with respect to a lane boundary; comparing the current TTLB value to the TTLB threshold value; and outputting a signal indicative of vehicle proximity to the lane boundary if the current TTLB value satisfies a triggering condition with respect to the TTLB threshold value.
