Systems and method for controlling braking at a trailer based on forward looking imaging sensor data

A system comprising:

• memory;
• and
• at least one processor in communication with the memory and configured to:
• receive instructions to initiate braking of a vehicle and a trailer coupled with the vehicle;
• receive information from an imaging sensor, the information comprising at least data regarding a forward-looking view from the vehicle;
• receive vehicle performance information regarding the vehicle and the trailer;
• determine a predicted path of the vehicle and trailer based on the information from the imaging sensor and the vehicle performance information;
• determine autonomous braking controls for the vehicle and the trailer based on the predicted path;
• and
• transmit the autonomous braking controls to the trailer, where the autonomous braking controls are configured to adjust a braking pressure level and a braking duration at the trailer as the vehicle and trailer travel through at least a portion of the predicted path;
• wherein:
• the predicated path comprises a first braking zone and a second braking zone in a path of the vehicle, wherein the first braking zone is a straight path and the second braking zone includes a curve;
• and
• the autonomous braking controls for the trailer in the first braking zone in the predicted path provide for up to full braking and the autonomous braking controls for the trailer in the second braking zone in the predicted path comprise a pulsing duty cycle that is adjusted based on a degree of a radius of the curve and a speed of the vehicle in the second braking zone.
