ABSTRACT:
An engine compression brake control device is disclosed. The control device is electronic and prevents activation of the engine compression brakes during operating states wherein undesirable conditions will result if the engine brakes are active. The electronic control device monitors various conditions and activates the engine brakes only if all of the following conditions are simultaneously detected: a valid gear ratio is detected; the driver has requested or enabled engine compression brake operation; the clutch pedal is out; the throttle is at a minimum engine speed position; and the electronic controller is not presently attempting to execute an electronically controlled final drive gear shift.
