Abstract
A vehicle brake controller includes a variable pulse-width modulator operating at a constant frequency and with a variable pulse width to provide control pulses to a MOSFET element which actuates vehicle braking. The controller further includes a visual indicator which displays different colors to representatively indicate the amount of current applied to the brakes, and also to indicate whether an operable connection exists between the electronic controller and the vehicle brakes.
