System to automate hitching a trailer
A vehicle hitch assistance system includes comprising an imaging system, a steering system, a dead reckoning device and a controller. The controller determines a hitch location within a vehicle exterior image received from the imaging system and controls the steering system to guide the vehicle in a reverse direction to align a hitch ball of the vehicle with the hitch location, including by tracking the location of the vehicle using information received from the dead reckoning device.

Human machine interface for vehicle alignment in an acceptable hitch zone
A vehicle hitching assistance system includes a controller identifying a trailer coupler within a specified area relative to the vehicle. The specified area is defined between a maximum distance and a minimum distance from a rear of the vehicle and within left and right lateral vehicle control limits. The controller also outputs a steering signal to the vehicle to cause the vehicle to steer to align a hitch ball of the vehicle with the coupler.

IMPLEMENT CONTROL OF VEHICLE AND IMPLEMENT COMBINATION
An implement includes a global positioning system (GPS) receiver and an implement control system. The global positioning system receiver is configured to obtain position information for the implement. The implement control system is configured to determine a lateral error for the implement based on the position information, estimate a lateral error for a vehicle relative to the implement, the vehicle being attached to the implement, and steer the vehicle to guide the implement based on at least the lateral error for the implement and the lateral error for the vehicle.
Method for steering an articulated vehicle
A method for steering an articulated vehicle traveling on a road, the vehicle comprising a tractor and a trailer, the method comprising determining a position of the tractor in relation to the road, and adjusting the steering in dependence on the determined tractor position. The method further comprises determining an orientation of the trailer in relation to the road, and/or an angular velocity of the trailer in relation to the road, and adjusting the steering in dependence on the determined trailer orientation and/or the determined angular velocity.

BOOSTER STEERING LOCK AND LOAD RELIEF CONTROL SYSTEM
A booster for a trailer system is provided comprising a control system in communication with a sensor(s) for determining the direction and speed of the booster when in motion. The control system comprises instructions corresponding to one or more booster operations such as: detection of a reverse state, retraction of a suspension system when the reverse state is detected; engagement of a steer axle lock when the reverse state is detected; detection of a forward state; extension of the suspension system when the forward state is detected; disengagement of the steer axle lock when the forward state is detected; detection of a high-speed forward state; engagement of the steer axle lock when the high-speed forward state is detected; detection of a low-speed forward state; and disengagement of the steer axle lock when the low-speed forward state is detected.

Configuring motion planning for a self-driving tractor unit
A control system of a self-driving tractor can access sensor data to determine a set of trailer configuration parameters of a cargo trailer coupled to the self-driving tractor. Based on the set of trailer configuration parameters, the control system can configure a motion planning model for autonomously controlling the acceleration, braking, and steering systems of the tractor.
