The shift stage is set according to the shift pattern in which the point is moved to the high-speed area, and the corresponding shift signal is output. After the accelerator pedal is operated, the shift pedal outputs the shift signal according to the original shift pattern. A shift control unit; The engine brake device by the change of the shift pattern during rapid deceleration comprising a shift drive unit that performs a shift operation for determining a shift stage according to a shift signal applied by the shift control unit may cause a downshift when rapid deceleration occurs during high speed driving. By shifting the shift point of the shift pattern to the high speed range, the down shift occurs even at high speed, and the engine brake effect is obtained. The foot brake is prevented from being worn due to excessive braking force, and the durability is improved to ensure safe driving. And a method can be provided.
