Abstract:
An auxiliary brake system comprising:a turbocharger operable to variably adjust a supercharging degree;an engine brake unit for generating an engine brake force by discharging suction air, compressed in a combustion chamber of an internal combustion engine, at timing in the vicinity of compression top dead center of the internal combustion engine;a controller for driving said turbocharger, when said engine brake unit is in operation, so as to permit the supercharging degree to become larger than that attained when said engine brake unit is disabled; andengine load detecting means for detecting a Load state of the internal combustion engine,wherein said engine brake unit is rendered operative when said engine load detecting means detects that a load applied to the internal combustion engine is smaller than a predetermined load indicative of the deceleration of the vehicle.
