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.

Abstract: An electronic brake controller for actuating electric wheel brakes of a towed vehicle in response to braking of an associated towing vehicle. The controller includes a microprocessor responsive to the braking of the towing vehicle for generating an output signal for actuating the towed vehicle brakes in accordance with a brake response curve. The brake response curve can include a non-linear portion.

Abstract: A mono-stable brake system having a mono-stable magnetic array composed of one or more permanent magnets and one or more electromagnets, the stable brake system condition being the brake applied mode in which the magnetic array is magnetically latched by permanent magnet power, without any electromagnet power, to a rotatable member being braked. To release the brake, the permanent magnet field strength is neutralized or at least decreased by appropriate energization of the one or more electromagnets until the magnetic array is moved by magnetic force away from the rotatable member being braked. The brake is preferably in a vehicle braking system, and particularly a trailer braking system, in which the electromagnets are kept energized at all times when the brake is released for trailer movements. The amount of brake application in the service braking mode is controlled by decreasing the magnetic field strength of the one or more electromagnets in accordance with the braking action demand placed on the system.
