Abstract: A tow bar system for an independently steered and powered trailer includes a front tow bar configured to removably couple to a hitch of a lead vehicle, a rear tow bar configured to removably couple to a hitch of the trailer, and a damper system disposed between the front tow bar and the rear tow bar. The damper system is configured to absorb compressive and tensile loads occurring during steering, accelerating, and braking of the independently steered and powered trailer.

Abstract: A trailer platform system with independent propulsion and control includes a steerable first axle connected to a pair of first wheels, a second axle connected to a pair of second wheels, and at least one electric traction motor configured to drive the steerable first axle and/or the second axle. A high voltage battery system is configured to power the at least one electric traction motor. A load platform is supported by a chassis and a suspension, wherein the load platform is a wagon-style platform with the first and second wheels located at the four corners of the load platform. A lead vehicle hitch connection is configured to removably couple to a lead vehicle.

Abstract: A trailer system with independent propulsion and control is configured to be towed by a lead vehicle. The trailer system includes a steerable first axle connected to a pair of first wheels, a second axle connected to a pair of second wheels, at least one electric traction motor configured to drive the steerable first axle, and a high voltage battery system configured to power the at least one electric traction motor. A trailer control system (TCS) includes a controller configured to steer, accelerate, and brake the first and/or second wheels. A trailer sensor suite is in signal communication with the TCS. The TCS is configured for signal communication with a lead vehicle sensor suite, and is configured to control driving and/or operation of the trailer system based on one or more signals from the trailer sensor suite and the lead vehicle sensor suite.

Abstract: A dolly platform system with independent propulsion and control is configured to support a trailer and includes a steerable first axle connected to a pair of first wheels, a second axle connected to a pair of second wheels, and at least one electric traction motor configured to drive the steerable first and/or second axle. The system further includes a high voltage battery system configured to power the at least one electric traction motor, a load platform having a trailer hitch structure configured to removably couple to the trailer, and a lead vehicle hitch connection configured to removably couple to a lead vehicle. An advanced driver assistance system (ADAS) or autonomous driving system includes a controller in signal communication with one or more sensors and/or cameras. The controller is configured to steer, accelerate, and brake the dolly platform system, based on signals from the one or more sensors and/or cameras.
