The invention discloses a multiplex circuit of vehicular relays, which is characterized in that two twin relays K1 and K3 carry out parallel output; a coil a of the twin relay K1 is connected with an anode of a gate lock motor; a coil b of the twin relay K1 is connected with a cathode of the gate lock motor and an anode of a back gate lock motor; a coil a of the twin relay K3 is connected with a cathode of the back gate lock motor and an anode of a rearview mirror folding and unfolding motor; and a coil b of the twin relay K3 is connected with a cathode of the rearview mirror folding and unfolding motor.With the adoption of the structure, the circuit does not adopt a relay multiplexing technology in comparison to direct driving, and the cost of the circuit is lowered by above 30%.The circuit adopts time sharing multiplexing at the same time and avoids heavy current when the motors are started synchronously.
