Abstract:
Systems, methods and computer program products for lane change detection and handling of lane keeping torque during an un-signaled lane change. Disclosed herein is an exemplary embodiment for a method including calculating a distance between a center of a vehicle and a center of a lane, determining a discontinuity in the calculation of the distance between the center of the vehicle and the center of a lane and disabling torque corrections to compensate for the discontinuity until the vehicle is near the center (position based) of the new lane and a certain time has elapsed (time based) from the detection of the discontinuity. Hysterisis or smoothly changing torque controls are offered to work with the Time and Position based lane change handling method.
