Abstract: An apparatus and system for automated operation of the brakes on a towed vehicle, in particular the conventional hydraulic brakes on an automotive vehicle, by controlled actuation of its own brake pedal or other such conventional operating component which is normally manipulated by the operator of the vehicle. The preferred embodiment of the system utilizes a power-actuated tension member such as a cable which is attachable to the towed vehicle brake pedal to pull it downward and thus apply the vehicle brakes in controlled response to commands from a controller mountable at a remote location such as on the towing vehicle, and the controller preferably includes, and operates in response to, an inertia sensor and related system which monitors deceleration of the towing vehicle caused by application of its brakes etc., as well as a manual control for selective optional braking of the towed vehicle by the tow vehicle driver at any desired time.

Abstract: A brake control unit for providing a brake output signal to a brake load includes a processor, an accelerometer and a memory subsystem. The accelerometer is coupled to the processor and provides a brake control signal to the processor, which is configured to provide the brake output signal to the brake load in response to the brake control signal. The memory subsystem is coupled to the processor and stores processor executable code, which causes the processor to automatically set at least one of a gain level and a boost level for the brake control unit.

The accelerometer is coupled to the processor and provides a brake control signal to the processor, which is configured to provide the brake output signal to the brake load in response to the brake control signal. The memory subsystem is coupled to the processor and stores processor executable code, which causes the processor to automatically acquire an operating point of the brake control signal when the brake control unit is mounted within a range of operating positions.

Abstract: An electrical charging circuit for applying a controlled charge to a receiving device, such as a battery, and particularly such as a battery carried on a towed vehicle such as a trailer for actuating the trailer brakes during emergency situations such as unexpected disconnection from the towing vehicle, i.e., break-away. In a basic sense, the charging circuit includes a voltage potential-responsive element or component for sensing the charged level of the receiving device coupled to the circuit and enabling or disabling the circuit charging operation, together with a variable-conductance circuit component for producing a generally constant charging voltage output to the receiving device over a wide range of applied voltages but also operable to provide a first amount of current flow to the receiving device at a given applied voltage and temperature but a second a limited amount of current flow when the voltage across the charging circuit is sufficiently large.

Abstract: An electronic brake controller for controlling the brakes of a towed vehicle in response to commands from the towing vehicle. The controller implements a microcontroller (10) that works in conjunction with analog circuit technology.

Abstract: An electronic controller for outputting pulses of current to actuate towed vehicle brakes includes a trigger point inertial sensor for varying the gain thereof. The trigger point inertial sensor includes a switch connected to the controller for switching the gain between two levels. In the preferred embodiment, the inertial sensor and switch comprise a mercury switch supported on a platform which is rotatable to adjust the switching threshold of the inertial sensor, and to adjust for the mounting position of the brake control.
