1. An electronic brake controller for actuating electric wheel brakes of a towed vehicle, the towed vehicle being associated with a towing vehicle having a set of wheel brakes, the electronic brake controller comprising:
- means for generating a triggering signal at a voltage level when the towing vehicle brakes are actuated;
a sensor for producing a brake control signal which is representative of a desired braking of the towed vehicle;
control means responsive to said triggering signal and said brake control signal for generating an output signal for actuating the electric wheel brakes of the towed vehicle; and
means for limiting said voltage level of said triggering signal such that said voltage level does not exceed a predetermined amount.

Abstract
An electronic brake controller for actuating electric wheel brakes of a towed vehicle in response to actuation of the brakes of an associated towing vehicle. The brake controller includes a sensor for producing a brake control signal which is representative of the desired braking of the towed vehicle. The controller also includes a microprocessor for responsive to the brake control signal for generating an output signal for actuating the electric wheel brakes of the towed vehicle.
