The invention discloses a control system for reducing quiescent current of a vehicle, and the control system comprises a battery energy-saving relay; the battery energy-saving relay is connected in series between a power supply and a vehicle-mounted electric appliance, and the battery energy-saving relay is used for switching off and switching on according to a control signal so as to control the vehicle-mounted electric appliance to switch off power supply; the control end of the battery energy-saving relay is connected with the vehicle body domain controller, and the vehicle body domain controller controls the battery energy-saving relay to be switched off and switched on according to the state of the whole vehicle. The system has the advantages that the relay is additionally arranged to control the electric appliances needing to work in a delayed mode in the forecabin, power supply of the electric appliances is directly cut off after the delayed work of the electric appliances of the vehicle meets the requirement, and therefore the number of the electric appliances needing to be dormant is reduced, the quiescent current of the whole vehicle is reduced, whole vehicle feed caused by too many dormant electric appliances of the whole vehicle can be reduced, the electric quantity safety of the battery is ensured, and the excessive damage to the service life is avoided.

    本发明公开了一种降低车辆静态电流的控制系统,包括电池节能继电器,所述电池节能继电器串接在电源和车载用电器之间,所述电池节能继电器用于根据控制信号来断开和闭合以控制车载用电器的断开供电;所述电池节能继电器的控制端与车身域控制器连接,所述车身域控制器根据整车状态来控制电池节能继电器的断开与闭合。本发明的优点在于:增设继电器来控制前舱需要延时工作的用电器,在车辆用电器延时工作达到要求后直接断开用电器的供电,从而减少需要休眠的用电器数量,进而降低整车静态电流且可以降低整车因休眠电器过多造成的整车馈电,保证了电池的电量安全以及避免寿命的过多损伤。
