    • The present invention relates to a start-stop “mild hybrid” vehicle with a starting system which utilizes traditional engine and transmission architecture. The present invention separates the pinion actuator solenoid from the starter motor power switching circuit. A power relay is provided to switch the starter motor. The pinion gear in the present invention is pre-shuttled to, and held in mesh with, the flywheel ring gear during engine stop conditions. A “prime current” is then applied to the power relay just below that which is required to energize the power relay. Upon request for an engine start, the current will increase to energize the relay and allow the starter motor to spin. A significant amount of time lag is thusly removed from the starting system permitting an expedient restart and launch. The pinion actuator solenoid in this invention may also have two coils which may be selectively energized.
    • 本发明涉及一种采用传统发动机和传动结构的启动系统的起停“轻度混合动力”车辆。 本发明将小齿轮致动器螺线管与起动马达功率切换电路分离。 提供电源继电器来切换起动电机。 本发明中的小齿轮在发动机停止条件期间被预先往飞轮齿圈啮合并保持与其啮合。 然后将“主电流”施加到刚好低于为功率继电器通电所需的功率继电器。 要求发动机启动时,电流将增加以使继电器通电并允许起动电机旋转。 因此,可以从启动系统中移除大量的时间延迟,从而允许重新启动和启动。 本发明中的小齿轮致动器螺线管还可以具有可以选择性地通电的两个线圈。
