The invention relates to an electric auxiliary device (10) for a motor vehicle, comprising an electronic high-voltage motor (12) driven by an electronic high-voltage power circuit (HVC), an electronic low-voltage control circuit (LVC) electrically isolated from the electronic high-voltage power circuit (HVC), and a wake-up unit (15) for waking up the electronic high-voltage power circuit (HVC), the wake-up unit (15) comprises a low voltage wake-up input port (41) for receiving a single wake-up edge, an inductive coupling element (20) for inductively transmitting the single wake-up edge to a releasable latch unit (30) which converts the single wake-up edge to a set constant high voltage activity signal level, the set constant high voltage activity signal level is used to indicate a non-sleep mode to an electronic high voltage power circuit (HVC). The invention allows waking up the control unit (60) of the motor vehicle electric coolant pump (10) from an energy-saving sleep mode.
本发明涉及一种机动车电动辅助装置(10),该机动车电动辅助装置具有由电子高压电力电路(HVC)驱动的电子高压马达(12)、与电子高压电力电路(HVC)电隔离的电子低压控制电路(LVC)以及用于唤醒电子高压电力电路(HVC)的唤醒单元(15),该唤醒单元(15)包括用于接收单个唤醒边沿的低压唤醒输入端口(41)、用于将单个唤醒边沿感应地传输至可释放锁存单元(30)的感应耦合元件(20),该可释放锁存单元(30)将单个唤醒边沿转换为设定的恒定高压活动信号电平,该设定的恒定高压活动信号电平用于向电子高压电力电路(HVC)指示非休眠模式。本发明允许将机动车电动冷却剂泵(10)的控制单元(60)从节能休眠模式唤醒。
