The invention discloses a control signal transmission circuit, vehicle-mounted electronic equipment and a vehicle, and relates to the technical field of electronic circuits. The circuit comprises a passive transmission module, an active transmission module and an enabling power supply module, a passive transmission first port of the passive transmission module is electrically connected with an active transmission second port of the active transmission module and then serves as an I/O transmission port of the control signal transmission circuit, and a passive transmission second port of the passive transmission module serves as a passive output port of the control signal transmission circuit. A first active transmission port of the active transmission module is electrically connected with a first enabling power supply port of the enabling power supply module and then serves as an enabling signal port of the control signal transmission circuit, and a third active transmission port of the active transmission module is electrically connected with a second enabling power supply port of the enabling power supply module. By implementing the technical scheme disclosed by the invention, the signal in two-way transmission can multiplex a single hard wire; hard wire resources are saved, and the wiring space is saved; and the material cost is reduced.
