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.
Claims9
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.
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 responsive to an actuation of the towing vehicle brakes for producing a brake control signal which is representative of a desired braking of the towed vehicle;
- a microprocessor responsive to said brake control signal for generating an output signal for actuating the electric wheel brakes of the towed vehicle, said microprocessor including a memory, said memory storing a plurality of microprocessor gains which relate said output signal to said brake control signal;
- and
- operator actuated means for selecting one of said plurality of gains from said memory, said microprocessor being responsive to said selected gain to generate said output signal.
