The invention relates to a dormancy awakening circuit of a vehicle parking brake controller and a control method, and belongs to the technical field of circuit control. Comprising a vehicle constant electric signal, a vehicle ignition signal, a voltage division circuit, a C1 filtering double-diode D2 amplitude limiting circuit, an LDO voltage stabilizing device, a low conduction voltage drop diode D1, a power supply circuit, a power supply dormancy awakening control circuit and a main processor, the power supply dormancy awakening control circuit comprises a resistor R1, a resistor R2, a resistor R3 and a triode Q1, and the voltage division circuit comprises a resistor R4 and a resistor R5. The invention provides a dormancy wake-up circuit of a vehicle parking brake controller and a control method, and the dormancy wake-up circuit is mainly characterized in that an LDO (Low Dropout Regulator), a low dropout diode and a main processor are matched to realize the opening and closing of a power supply circuit, so that the controlled dormancy and wake-up states are switched according to conditions. The purposes of reducing cost, simplifying circuit structure, further reducing static power consumption and saving electric energy are achieved.
