Abstract: A trailer backup assist system is provided herein. The system includes a calibration feature for calibrating an imaging device used for hitch angle detection. The system also employs multiple hitch angle detection methods, a number of which may run in parallel to increase the intervals at which a hitch angle can be measured. The system additionally includes a predictive feature in which a hitch angle can be predicted in instances where a trailer sensing device fails. The system is further configured to estimate a trailer length and generate steering commands that are invariant to the estimated trailer length under certain conditions.

Abstract: Systems and methods for cancelling brake torque variation in a motor vehicle are disclosed. Signals indicative of brake torque variation are received at a controller. Based on the signals, a frequency associated with the indicated brake torque variation is determined. At least one of an output time and output volume of pressurized brake fluid is adjusted based on the frequency to cancel the indicated brake torque variation.

Abstract: A first computer including a processor is programmed to receive an indication of a failure mode in a vehicle and wirelessly transmit the indication of the failure mode to a remote server. The computer is further programmed to receive a revised route to a destination based at least in part on the failure mode and operate the vehicle along the revised route.

Abstract: A vehicle parking brake system includes a power bridge. The power bridge is electrically connected to a primary power source and to a secondary power source. The power bridge has a first condition in which the primary power source is active in which the primary source is electrically connected to a parking brake actuator. The power bridge has a second condition in which the primary power source is not active in which the secondary power source is electrically connected to the parking brake.

A direction of the vehicle is controlled based at least in part the curvature performance profile.

Abstract: A current value of a state-of-motion from a second controller can be received by a first controller. The first controller determines a subset of a target value of the state-of-motion to be achieved by a subsystem and transmits a command to a third controller in communication with the subsystem to achieve the subset of the target value of the state-of-motion. The third controller commands the subsystem to approach the subset of the target value of the state-of-motion.
