DRIVE CONTROL SYSTEM

A drive control system includes an engine, an electric turbocharger, and a controller. The engine includes a cylinder and a piston provided in a slidable manner inside the cylinder and rotates a crankshaft in accordance with sliding of the piston. The electric turbocharger supplies compressed air into the cylinder. The controller controls the engine and the electric turbocharger. The controller includes at least one processor and at least one memory coupled to the processor. The processor transmits a stoppage signal for stopping the engine to the engine, and stops the piston at a position where a crank angle is within a predetermined range from 60° before a top dead center to 30° before the top dead center by causing the electric turbocharger to supply the compressed air into the cylinder in a period from when the stoppage signal is transmitted to when stopping the engine is completed.
