Abstract: In an engine starting apparatus, a starter control unit is configured to, upon command to start the engine, put a starter in a drive ON state to begin cranking of the engine and then put the starter in a drive OFF state at a predetermined timing. The starter control unit is configured to, when acceleration is requested within a predetermined time period from the command to start the engine, keep the starter in the drive ON state even after the time when the starter would be put in the drive OFF state without the acceleration request within the predetermined time period, and drive the starter to torque-assist the engine, thereby performing an assist mode in which both the engine) and the starter serve as drive sources for driving a vehicle.

Abstract translation: 在发动机起动装置中，起动控制单元构成为，在启动发动机的命令时，将起动器置于驱动器接通状态，开始发动机的起动，然后在预定的时刻将起动器置于驱动关闭状态。 起动控制单元被配置为当从启动发动机的命令的预定时间段内请求加速时，即使在起动器将被置于驱动器关闭状态的时间内也将起动器保持在驱动器接通状态，而没有 在预定时间段内加速请求，并且驱动起动器来对发动机进行扭矩辅助，从而执行辅助模式，其中发动机）和起动器都用作驱动车辆的驱动源。
