An electric trailer brake system includes an electric brake receiving energy from a battery. The battery is recharged by a generator disposed on the trailer independent from the towing vehicle. Recharging the batteries that power the electric brake assemblies on the trailer minimizes the effects of power restrictions caused by a standard sized connector and cable connection between the towing vehicle and cargo trailer.

Brake by wire power source

A brake actuator assembly includes a sensor mounted to a push rod which is in communication with a transceiver antenna. The sensor provides positional information of the push rod relative to the antenna. A clearance between a friction element and a rotating brake member is determined based on displacement of the push rod and known mechanical relationships within the brake actuator.

A data logging system includes a data logging unit, a primary power source, an auxiliary power source and a controller. The controller detects whether the primary power source is available or unavailable and the time at which it became available or unavailable. From the time data the controller will then determine the total time the primary power source was unavailable to power the system. The controller adjusts or increases a predetermined auxiliary power source value by the auxiliary power source usage time period. Upon each occurrence in which the primary power source again becomes unavailable, the controller performs the same operations and further adjust or increases the previously reduced predetermined auxiliary power source value by the next auxiliary power source usage time period. Adjusting or increasing the predetermined auxiliary power source value will continue until a predetermined value is reached which triggers an alert. The alert indicates to an operator that the system requires service.
