Abstract
A pull-drift compensation controller device for a vehicle configured to perform operations including identifying a current pull-drift compensation torque and a current driver input torque while in an adapt-and-compensate state in which pull-drift compensation torque is learned and applied, wherein the vehicle is moving at a substantially straight heading; and performing a transition from a normal pull-drift compensation adjustment sub-state of the adapt-and-compensate state to a fast pull-drift compensation adjustment sub-state of the adapt-and-compensate state based on the current driver torque opposing the direction of the current pull-drift compensation torque without a change in the heading.
Claims18
A pull-drift compensation controller device for a vehicle configured to perform operations comprising:
- identifying a current pull-drift compensation torque and a current driver input torque while in an adapt-and-compensate state in which pull-drift compensation torque is learned and applied, wherein the vehicle is moving at a substantially straight heading;
- and
- performing a transition from a normal pull-drift compensation adjustment sub-state of the adapt-and-compensate state to a fast pull-drift compensation adjustment sub-state of the adapt-and-compensate state based on the current driver torque opposing the direction of the current pull-drift compensation torque without a change in the heading.
A method, comprising:
- identifying a current pull-drift compensation torque and a current driver input torque while in an adapt-and-compensate state in a vehicle moving at a substantially straight heading;
- and
- performing, by a pull-drift compensation controller, a transition from a normal pull-drift compensation adjustment sub-state of the adapt-and-compensate state to a fast pull-drift compensation adjustment sub-state based on the current driver torque opposing the direction of the current pull-drift compensation torque without a heading change.
A pull-drift compensation controller device for a vehicle configured to perform operations comprising:
- identifying a pull-drift compensation torque and a driver input torque opposing for a predetermined reset threshold;
- and
- performing, based on the pull-drift compensation torque and a driver input torque opposing for the predetermined reset threshold, a transition from a compensate-only state in which pull-drift compensation torque is applied but not learned to a reset state in which the pull-drift compensation torque is reset to a default value and neither learning nor applying pull-drift compensation torque is performed.
