Vehicle door lock control device

A vehicle door lock control device post-installed on a vehicle including an actuator to actuate a vehicle door lock mechanism;

• a genuine door locking switch including a locking signal lead wire, an unlocking signal lead wire and a neutral lead wire, the locking signal lead wire and the neutral lead wire being conducted through the door locking switch or being cut off by the door locking switch, the unlocking signal lead wire and the neutral lead wire being conducted through the door locking switch or being cut off by the door locking switch, and an actuator control unit which is connected to the genuine door locking switch via the locking signal lead wire, the unlocking signal lead wire and the neutral lead wire, the actuator control unit actuating the actuator so that a door is locked when the locking signal lead wire and the neutral lead wire are conducted, the actuator control unit actuating the actuator so that the door is unlocked when the unlocking lead wire and the neutral lead wire are conducted, the vehicle door locking device comprising:
• a locking relay having a fixed contact connectable to either one of the locking signal lead wire and the neutral lead wire via a first interrupt connection terminal and a movable contact connectable to the other of the locking signal lead wire and the neutral lead wire via a second interrupt connection terminal;
• a locking concealed switch mountable on an exterior of a vehicle body;
• and
• a locking relay control unit which is connectable to a permanent power supply of the vehicle and is connected to the locking concealed switch, the locking relay control unit controlling the locking relay so that the movable contact of the locking relay is connected to the fixed contact when the locking concealed switch is manually operated,
• wherein the first and second interrupt connection terminals include metal needles which are thrust into the locking signal lead wire and the neutral lead wire thereby to be electrically connectable to the locking signal lead wire and the neutral lead wire, respectively.

A vehicle door lock control device post-installed on a vehicle including a genuine door locking switch supplying a door locking signal and a door unlocking signal, a genuine door locking unit having a genuine locking relay and a genuine unlocking relay and a door locking motor, the genuine locking relay being actuated to drive the door locking motor for normal rotation when the door locking signal has been supplied to the genuine door locking control unit, the genuine unlocking relay being actuated to drive the door locking motor for reverse rotation when the door unlocking signal has been supplied to the genuine door locking control unit, the vehicle door lock control device comprising:

• a non-genuine unlocking relay having a movable contact connectable via a first interrupt connection terminal to a first cut end of a lead wire connecting between the genuine unlocking relay and the door locking motor, the first cut end being located at the door locking motor side, a first fixed contact connectable via a second interrupt connection terminal to a second cut end of the lead wire connecting between the genuine unlocking relay and the door locking motor, the second cut end being located at the genuine unlocking relay side, and a second fixed terminal connectable to a permanent power supply of the vehicle;
• an unlocking concealed switch mountable on an exterior of a vehicle body;
• and
• a non-genuine unlocking relay control unit which is connectable to a permanent power supply of the vehicle and connected to the unlocking concealed switch, the non-genuine unlocking relay control unit being configured to control the non-genuine unlocking relay so that the movable contact of the non-genuine unlocking relay is switched from the first fixed contact to the second fixed contact thereby to be connected to the second fixed contact when the unlocking concealed switch has been manually operated, wherein the first and second interrupt connection terminals include metal needles which are thrust into the lead wires thereby to be electrically connectable to the lead wire, respectively.
