Abstract
An electric trailer brake controller includes a deceleration sensor for generating a brake control signal. The controller also includes a device to decrease the sensitivity of the deceleration sensor to spurious inputs. Additionally, the controller includes a brake current limiting circuit that progressively reduces the current supplied to the controlled trailer brake when the brake current exceeds a predetermined level.
