Single-wire bidirectional wake-up circuit and vehicle

The embodiment of the invention discloses a single-wire bi-directional wake-up circuit and a vehicle. The single-wire bi-directional wake-up circuit is used for a controller and comprises a first interface, a second interface, a third interface, an external wake-up module and an internal wake-up module. The first interface is used for connecting the input port of the current controller. The secondinterface is used for connecting the output port of the current controller. A third interface is used for connecting with a third interface of another controller; The external wake-up module is positioned between the first interface and the third interface. The external wake-up module includes a first transistor. When the first interface receives an external wake-up signal, the first transistor is conducted, and the third interface outputs the external wake-up signal. The internal wake-up module is positioned between the second interface and the third interface and includes a second transistor which is conducted when
