A trailer brake controller 10 for use in a passenger vehicle 12 is provided, including a control element 11 positioned within the passenger vehicle 12, a vehicle speed input 16 and a vehicle brake pressure input 14 providing speed and brake pressure data to the control element 11, and a trailer brake output 18 sending a signal to the trailer in response to the vehicle speed input 16 and the vehicle brake pressure input 14.

A micro processor based electric brake controller includes a multi-axis accelerometer that senses deceleration of a towing vehicle along a plurality of directional axes. The controller also includes a microprocessor that is responsive to the sensed decelerations to supply power to trailer brakes that is a function of the deceleration.

A control system for actuating a trailer braking system on a trailer is disclosed. The control system includes a trailer brake controller in communication with an antilock braking controller and an electronic stability controller of a towing vehicle to receive a wheel speed, a brake pressure, a yaw rate, a lateral acceleration, and a steering angle. The trailer brake controller utilizes the wheel speed, the brake pressure, the yaw rate, the lateral acceleration, and the steering angle to determine the attitude of the towing vehicle, and to calculate a desired braking force for the trailer. The trailer brake controller sends an appropriate output to actuate the trailer braking system on the trailer to stabilize the towing vehicle during extreme braking conditions.

A towed vehicle controller combines a trailer brake controller and lighting driver. The towed vehicle controller can include a trailer battery charging circuit. The towed vehicle controller operates towed vehicle braking, towed vehicle lighting and towed vehicle battery charge functions.

A braking system for a combined tractor-trailer assembly wherein a leading trailer is coupled to a towing tractor and a trailing trailer is coupled to the leading trailer. All of the wheels of the trailers are provided with brakes which may be applied and released in response to the operation of a brake control pedal operated by a driver in the tractor. The brakes also may be applied to the trailing trailer whenever the latter is parked. The brakes of the trailing trailer normally are maintained in applied condition by a spring assisted mechanism when such trailer is parked. Such mechanism normally is disabled by pressurized fluid when the trailer is in service and the pressured fluid is accessible via a valve which simultaneously enables the parking brakes and service brakes simultaneously to be coupled to and uncoupled from the pressure fluid system.

The invention discloses a brake controller for a bicycle pedal brake device, which mainly comprises a braking ratchet mechanism, brake cables and torsion springs. The braking ratchet mechanism comprises a cylindrical brake cable fixing tube which is arranged in a middle shaft tube below a frame and fixedly sleeved in the middle of a middle shaft, the cylindrical brake cable fixing tube is combined with the middle shaft to form the braking ratchet mechanism, the brake cables are arranged on the outer wall of the brake cable fixing tube and extend out of the middle shaft, the braking ratchet mechanism is in linkage with the middle shaft and used for winding and tightening the brake cables so as to pull braking brakes on a front wheel and a rear wheel to brake when a rider reversely pedals, and is not in linkage with the middle shaft when the rider forwardly pedals, the torsion springs are sleeved outside the brake cable fixing tube, and one end of each torsion spring is connected with the middle shaft tube while the other end of each torsion spring is fixed onto the brake cable fixing tube. The brake controller realizes braking of the front wheel and the rear wheel by reversely pedaling, is simple and direct in brake pedaling actions and safe and reliable in braking.
