Systems, methods and computer program products for lane change detection and handling of lane keeping torque
First Claim
1. A method for lane change detection and handling of lane keeping torque, the method comprising:
- detecting a driver input torque exceeding a threshold value;
disengaging a lane keeping torque in response to said driver input torque exceeding said threshold value;
detecting said driver input torque decreasing below a threshold value;
calculating a time period; and
re-engaging a lane keeping torque in response to an expiration of the time period.

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.

12. A method for lane change detection and handling of lane keeping torque, the method comprising:
-
detecting a movement of a vehicle from a first lane to a second lane; increasing a first torque to the vehicle to retain the vehicle in the first lane; detecting further movement of the vehicle from the first lane to the second lane; in response to detecting the further movement of the vehicle from the first lane to the second lane, decreasing the first torque to the vehicle; and applying a second torque to the vehicle to retain the vehicle in the second lane.
