Vehicle window opening and closing control device

A vehicle window opening and closing control device comprising:

• a driver seat unit that controls opening and closing of a window based on a manipulation of a switch provided in a driver seat of a vehicle;
• and an other-seat unit that controls the opening and closing of the window based on a manipulation of a switch provided in any other seat except the driver seat, wherein the driver seat unit includes a driver seat switch that opens and closes the window of the driver seat and an other-seat switch that opens and closes the window of any other seat, the other-seat unit includes a switch that opens and closes the window of the any other seat, the driver seat unit and the other-seat unit are connected by a single signal line, the other-seat unit includes a first relay and a second relay, which switch a direction of a current passed through a window opening and closing motor, the switch of the other-seat unit includes a window opening switch that is manipulated in opening the window and a window closing switch that is manipulated in closing the window, the current is passed through a coil of the second relay from a power supply via the window closing switch and a forward current is passed through the motor to normally rotate the motor by switching a contact of the second relay when the window closing switch is manipulated by the other-seat unit, the current is passed through a coil of the first relay from the power supply via the window opening switch and a reverse current is passed through the motor to reversely rotate the motor by switching a contact of the first relay when the window opening switch is manipulated by the other-seat unit, the current is passed through a route to the coil of the second relay from the power supply via the driver seat unit, the signal line, and the window closing switch and the forward current is passed through the motor to normally rotate the motor by switching the contact of the second relay when the other-seat switch is manipulated onto a window closing side by the driver seat unit, and the current is passed through a route to the driver seat unit from the power supply via the window opening switch, the coil of the first relay, and the signal line and the reverse current is passed through the motor to reversely rotate the motor by switching the contact of the first relay when the other-seat switch is manipulated onto a window opening side by the driver seat unit.
