    • The purpose of the present invention is providing a supercharging system which uses both of a mechanism such as VN or the like and an electric motor generating an assist force while making the supercharger operate smoothly when the assist by the electric motor is stopped. The system controls the electric motor in a feedback manner so that enough assist force is generated (FIG. 2A and FIG. 2B) while controlling the VN in an open manner (FIG. 2D) until status of the supercharger reaches target status (time t1) when an accelerator requirement arises in a low revolution region. The control of the electric motor is changed to an open control, and the control of the VN is changed to a feedback control, respectively, at time t1. The open control of the electric motor is continued so that necessary complement torque occurs until time t2. After time t2, the system maintains the target status only by the feedback control of the VN.
    • 本发明的目的是提供一种增压系统,其使用诸如VN等的机构和产生辅助力的电动机,同时当电动机的辅助停止时使增压器平稳地工作。 该系统以反馈方式控制电动机,从而在开启状态下控制VN(图2D)直到增压器的状态达到目标状态(时间t1)(图2A和图2B) )当在低转速区域出现加速器要求时。 电动机的控制变为开启控制,并且在时间t1分别将VN的控制改变为反馈控制。 电动机的打开控制继续进行,直到时间t2发生必要的补偿转矩。 在时间t2之后,系统仅通过VN的反馈控制来维持目标状态。
