Abstract
A remote control circuit for regulating current to electric trailer brakes as a function of the brake fluid pressure within the tractor brake system or in response to activation of a control arm by the tractor operator. A hydraulic transducer is connected directly to the tractor brake system to produce an electrical signal at the control circuit which varies as a function of the hydraulic fluid pressure. An electromagnetic, pressure-responsive circuit is also provided which is operatively connected to the trailer brakes and which retards movement of the operator control arm at the control circuit in proportion to the brake torque applied at the trailer.
Claims5
In an electronic brake control circuit for trailers equipped with electric brakes of the type in which brake torque is a function of electric current through an electromagnetic brake coil, said control circuit including means to provide an output to said coil as a function of displacement of an operator-responsive control arm, the combination comprising means to provide an electrical signal which varies as a function of said controller output, and electromagnetic means magnetically coupled to said control arm to retard displacement thereof as a function of said electrical signal.
