Title: Engine brake control apparatus and method

Abstract

This patent describes a compression brake controller for use with a vehicle having an engine, a clutch, a transmission, a compression brake apparatus having a brake input and activated in response to signals supplied to the brake input, and a throttle control device. It comprises fuel metering means for controlling fuel delivery to the engine; throttle position sensor means for sensing the position of the throttle control device; pressure sensor means in fluid communication with the intake manifold of the engine; control circuit means for supplying a fueling signal to the fuel signal input in accordance with the throttle signal; RPM sensor means for producing an RPM signal corresponding to engine RPM; and brake circuit means for supplying a braking signal to the brake input of the compression brake apparatus in accordance with concurrence of the following conditions. This patent also describes a method for activating and deactivating a compression brake in an internal combustion having a throttle control. It comprises detecting a throttle control position below a predetermined throttle limit; detecting an intake manifold pressure below a predetermined pressure limit; detecting an engine speed above a predetermined RPM limit; detecting a fuel metering signal corresponding to a fueling ratemore » below a predetermined fueling limit.« less
