APPARATUS FOR SIMULTANEOUSLY APPLYING BRAKES OF A TOWED VEHICLE HAVING A SELF CONTAINED BRAKING SYSTEM WHEN BRAKES OF A TOWING VEHICLE ARE APPLIED

摘要

An apparatus for simultaneously applying brakes of a towed vehicle having a self contained braking system when brakes of a towing vehicle are applied is described. This apparatus includes a vacuum pump linked with a vacuum booster in the braking system of the towed vehicle thereby providing vacuum pressure to the vacuum booster. A servomotor linked with a brake pedal in the braking system of the towed vehicle. Upon activation, the servomotor provides force to move the brake pedal thereby applying the brakes in the towed vehicle. A pedal position sensor is linked with the brake pedal in the towing vehicle, whereby the brake pedal position of the towing vehicle is sensed. An encoder is linked with the pedal position sensor. The encoder receives data from the pedal position sensor regarding the brake pedal position of the towing vehicle and encodes such data. A decoder is linked with the encoder and the servomotor. The decoder receives an encoded signal from the encoder regarding the brake pedal position of the towing vehicle and sends a decoded signal to the servomotor to move the brake pedal of the towed vehicle thereby creating a master to slave connection between the brake pedal of the towing vehicle and the brake pedal of the towed vehicle.
