Engine brake control integration with vehicle service brakes

摘要

An engine brake control system that is integrated with service brakes for a diesel engine powered vehicle. Three manually selectable modes of operation include an operation with the engine brake control system disabled, an operation with engine braking activated by a zero throttle application and engine braking power level determined by manually actuated dashboard switches or the like, and an operation with engine braking activated by a brake pedal and engine brake power level being proportional to brake pedal displacement and limited by the manually actuated dash-mounted switches or the like.
