Abstract
A system and method for providing adaptive lane centering in an autonomous or semi-autonomous vehicle driving system includes activating a lane centering control system, detecting a driver steering override of the lane centering control system, monitoring a lane centering offset when a driver override condition is detected, determining if the lane centering offset represents a driver bias and adjusting the lane centering offset in the lane centering control system to compensate for the driver bias.
Claims15
A method for providing adaptive lane centering in an autonomous or semi-autonomous vehicle driving system, said method comprising:
- a controller for:
- activating a lane centering control;
- detecting a driver steering override during the lane centering control;
- monitoring a lane centering offset when a driver override condition is detected;
- determining if the lane centering offset represents a driver bias;
- and
- determining if the driver override condition has ended prior to determining if the offset is a driver bias by detecting if the lane centering variation is smaller than a predetermined threshold for a predetermined time;
- and
- adjusting the lane centering offset to compensate for the driver bias.
A system for providing vehicle steering control in an autonomous or semi-autonomous vehicle driving system, said system including non-transitory computer-readable storage medium with an executable program stored thereon, wherein the program instructs a controller to:
- activate a lane centering control;
- detect a driver steering override of the lane centering control;
- monitor a lane centering offset when a driver override condition is detected;
- determine if the lane centering offset represents a driver bias;
- determine if the driver override condition has ended prior to determining if the offset is a driver bias by detecting if the lane centering variation is smaller than a predetermined threshold for a period of time;
- and
- adjust the lane centering offset to compensate for the driver bias.
A system for providing vehicle steering control in an autonomous or semi-autonomous vehicle driving system, said system comprising:
- a controller programmed to provide:
- means for activating a lane centering control;
- means for detecting a driver steering override of the lane centering control system;
- means for monitoring a lane centering offset when a driver override condition is detected;
- means for determining if the lane centering offset represents a driver bias;
- means for determining if the driver override condition has ended prior to determining if the offset is a driver bias by detecting if the lane centering variation is smaller than a predetermined threshold for a period of time;
- and
- means for adjusting the lane centering offset to compensate for the driver bias.
