摘要： 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. In a preferred embodiment, the brake controller includes an input circuit (16) for generating a brake level signal representing the braking force to be applied by the towed vehicle's brakes, a display circuit (22) including a plurality of indicator lights, a power switching circuit (24) adapted for coupling to the brakes of the towed vehicle and to the power supply of the towing vehicle, for selectively supplying power from the towing vehicle power supply to the brakes of the towed vehicle in response to a switching control signal supplied to a control input terminal, a current sensing circuit (26) for sensing a level of braking current supplied to the brakes of the towed vehicle through the power switching circuit (24), and for generating a current level signal representing the sensed level of braking current, and a microcontroller (10) for generating and supplying a switching control signal to the control input terminal of said power switching circuit (24) thereby causing the power switching circuit (24) to deliver a braking current to the brakes of the towed vehicle that is related to the brake level signal supplied to the microcontroller (10) by the input circuit (16), the microcontroller (10) illuminates one or more of the indicator lights of the display circuit (22) to indicate a relative level of braking of the towed vehicle brakes and controls one or more of the indicator lights to indicate that the towed vehicle brakes are or are not properly connected to the power switching circuit (24).

摘要： 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 acquire an operating point of the brake control signal when the brake control unit is mounted within a range of operating positions.

摘要： 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. The apparatus and system further includes a power unit typically mounted on the towed vehicle (e.g., under the hood) has a drive motor that operates through a controllable slip clutch, preferably a magnetically engageable and controllable clutch device, for generating the pulling force applied to the towed vehicle brake pedal by the cable/tension member. Also, the power unit preferably includes a vacuum pump or other power assist unit coupled to the towed vehicle power brake system unit, to enable use of that system when the brake pedal is pulled down by the cable during the remotely controlled braking process.

摘要： 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. In its most preferred embodiment, the voltage responsive component may be a diode switch, and the variable-conductance circuit component may be a positive temperature coefficient (PTC) thermistor.

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.
