    • A control device performs fuel injection without cranking when engine-speed Ne is within a first-range (Ne>N1) and an engine-restart request occurs. The device performs the cranking after the synchronization in rotation-speed between pinion and ring gears, and the gear meshing operation between them when the engine-speed Ne is within a second range (N1≧Ne>N2) and the engine-restart request occurs. The device performs the cranking after the gear meshing operation and drives a starter to rotate the pinion gear when the engine-speed Ne is within a third-range (N3≧Ne) and the above request occurs. When the above request occurs in an engine restart ready-range (N2≧Ne>N3), the control device performs the cranking after the engine-speed Ne is decreased to a value within the third-range (N3≧Ne) and after the completion of the gear meshing operation.
    • 当发动机速度Ne处于第一范围(Ne> N1)并且发动机重启请求发生时,控制装置执行燃料喷射而不起动。 在发动机速度Ne处于第二范围(N1≧Ne> N2)之内时,该装置在小齿轮和环形齿轮之间的转速同步之后进行起动,并且在它们之间的齿轮啮合操作,并且发动机重启请求 。 在发动机速度Ne处于第三范围(N3≥Ne)内并且发生上述要求之后,该装置在齿轮啮合操作之后执行起动并且驱动起动器使小齿轮旋转。 当在发动机重起准备范围(N2≥N3> N3)中发生上述要求时,控制装置在发动机速度Ne减小到第三范围(N3≥Ne)之内的值之后,执行起动 完成齿轮啮合操作。
