Abstract
In an engine starting system, a first controller activates, in response to a driver's starting request, a first starting device to rotate the rotating shaft of an engine. A second controller is communicably connected to the first controller. The second controller recognizes rotation of the rotor of a second starting device resulting from an activation of the first starting device. The second controller starts a power running operation of the second starting device based on the recognition of the rotation of the rotor. The first controller determines whether the power running operation of the second starting device has been started. The first controller deactivates, when it is determined that the power running operation has been started, the first starting device before a rotational angular position of the rotating shaft of the engine arrives at a compression top dead center of the engine.
