The utility model relates to a low-static power consumption vehicle body control system. The low-static power consumption vehicle body control system is characterized in that an MCU in a vehicle body controller is connected with a triode Q1, a triode Q2 and a diode D1, a coil end positive electrode of a relay for controlling a central power supply is connected to the exterior of the vehicle body controller, meanwhile, the interior of the vehicle body controller is connected with an ON-gear signal of an external ignition switch and the coil end positive electrode of the relay for controlling the central power supply through a diode D2, one end of a contact of the relay for controlling the central power supply is connected with a storage battery positive electrode B+, and the other end of the contact of the relay for controlling the central power supply outputs a controllable power supply; the central power supply is introduced for control, the number of vehicle body control modules using constant electricity all the time is effectively reduced, and therefore a first-stage static power consumption control mechanism is additionally arranged, and static power consumption is greatly reduced when a vehicle stops.
