The invention provides a wake-up circuit. In a passive wake-up module of the wake-up circuit, a first signal input end of a comparison unit is connected with a passive wake-up signal input end, and a first signal output end of the comparison unit is connected with a control end of a second switch. One end of the second switch is grounded and the other end is connected with the base electrode of the triode, one end of the tenth resistor, the first connecting end of the third capacitor and the second signal input end of the comparison unit; a collector of the triode is connected with the other end of the tenth resistor; a second connecting end of the third capacitor is grounded; one end of the fourth resistor is connected with the power supply, and the other end is connected with one end of the fifth resistor and a second reference signal input end of the comparison unit; the other end of the fifth resistor is grounded; the wake-up time of the input signal of the passive wake-up signal input end is adjusted by adjusting the resistance values of the fourth resistor and the fifth resistor. The invention further provides an automobile comprising the wake-up circuit.
