Abstract:
An engine brake control system in a vehicle in which fuel supply to a cylinder of an engine is cut off when a driver applies engine brake by releasing an accelerator pedal and thereby decreasing an engine throttle opening degree, the engine brake control system comprising:an actuator section capable of varying an engine braking torque during execution of fuel cutoff; anda controller section monitoring a degree of slipperiness of a road surface, calculating, from the degree of slipperiness, a limit engine braking torque which decreases as the degree of slipperiness increases, and decreasing the engine braking torque with increase in the degree of slipperiness by controlling the engine braking torque to a value corresponding to the limit engine braking torque by controlling the actuator.
