Abstract:
A controller for controlling the electric current supplied to at least one electric wheel brake comprising:a brake control signal generator which is adapted to be connected to a vehicle stop light switch, said brake control signal generator including a device for sensing deceleration of a towing vehicle and generating a brake control signal which is a function of the towing vehicle deceleration; a brake control signal amplifier having an input terminal and an output terminal, said brake control signal amplifier input terminal connected to said brake control signal generator, said amplifier operative to amplify said brake control signal, said brake control signal amplifier also having a feedback terminal, and feedback terminal connected through a feedback resistor to said brake control signal output terminal; at least one damping capacitor connected between said output and feedback terminals of said brake control signal amplifier, said damping capacitor operative to decrease the sensitivity of said deceleration sensor; an output signal generator having an input terminal which is connected to said output terminal of said brake control signal amplifier, said output signal generator also having an output terminal, said output signal generator being responsive to said amplified brake control signal to generate an output signal at said output terminal which is a function of said amplified brake control signal; and an electric current controller which is adapted to be connected between a vehicle power supply and the controlled electric wheel brake, said electric current controller coupled to said output terminal of said output signal generator, said electric current controller responsive to said output signal to supply an electric current to the controlled wheel brake which is a function of said output signal.
