Abstract: A vehicle system comprises a hitch ball mounted on a vehicle and a steering system configured to steer the vehicle. The system further comprises a controller configured to identify a coupler position of a trailer and control a motion of the vehicle at a rate aligning the hitch ball with the coupler position. In response to the rate below a speed threshold, the controller activates a standstill mode suspending a steering control of the steering system.

Abstract: A vehicle system is configured to control a trailer alignment routine. The system comprises a hitch ball mounted on a vehicle and a controller configured to identify a coupler position of a trailer. The controller is further configured to control motion of the vehicle to an aligned position, wherein the hitch ball is aligned with the coupler position. In response to the aligned position, the controller activates a service brake holding the vehicle and while maintaining the service brake activation, the controller activates a parking brake.

Abstract: A hitch assist system and method are provided herein. A human machine interface is configured to receive user-input specifying a target travel direction of a vehicle. A controller is configured to generate commands for autonomously maneuvering the vehicle in the target travel direction, identify a hitch coupler of a trailer based on input received from an object detection system, and request additional user-input updating the target travel direction if the hitch coupler is unable to be identified.

Abstract: A vehicle powertrain includes a controller, a torque converter, and an engine and electric machine coupled by a clutch. The torque converter may be configured to couple the electric machine to an output shaft. The controller may be programed to generate a command for the electric machine to output torque to drive the torque converter toward a desired rotational speed, and to modify the command according to a difference between the desired rotational speed and an actual rotational speed to reduce the difference, wherein values of the difference are limited by thresholds that change with powertrain operation.

Abstract: A table of engine torque correction factors is used to compensate for noise factors. In a hybrid vehicle, the motor is used to measure engine torque during periods of constant transmission input shaft torque. By comparing the measured input torque to the requested engine torque, a controller can update the table of correction factors to compensate for changes in the noise factors. A service procedure may be implemented that systematically provides the controller an opportunity to update many values in the table.
