Window opening-closing control system and window opening-closing control apparatus

摘要

If closing operation to the passenger's seat sub switch continues for not less than a prescribed time period Tb, a passenger's seat relay contact on a close side is turned ON. If the closing operation to the passenger's seat sub switch thereafter ends before a prescribed time period Tc elapses, the passenger's seat relay contact on the close side is kept ON. If opening operation to the passenger's seat sub switch continues for not less than the prescribed time period Tb, a passenger's seat relay contact on an open side is turned ON. If the opening operation to the passenger's seat sub switch thereafter ends before the prescribed time period Tc elapses, the passenger's seat relay contact on the open side is kept ON. The invention is applicable to an automatic window system and the like.

主权项

1. A window opening-closing control system configured to control opening and closing a window at a driver's seat and a window at a passenger's seat other than the driver's seat in a vehicle, the window opening-closing control system comprising:
a passenger's seat unit provided at the passenger's seat; and a window opening-closing control apparatus provided at the driver's seat and configured to control a driver's seat motor configured to open and close the window at the driver's seat and a passenger's seat motor configured to open and close the window at the passenger's seat; the passenger's seat unit including: a momentary passenger's seat sub switch having a first contact operated to close the window at the passenger's seat and a second contact operated to open the window at the passenger's seat; the first contact including: a first common terminal connected to a first end of the passenger's seat motor; a first normally opened terminal connected to a positive electrode of a power supply of the vehicle via a wire, and connected to the first common terminal in response to closing operation for closing the window at the passenger's seat; and a first normally closed terminal; the second contact including: a second common terminal connected to a second end of the passenger's seat motor; a second normally opened terminal connected to the positive electrode of the power supply via the wire, and connected to the second common terminal in response to opening operation for opening the window at the passenger's seat; and a second normally closed terminal; the window opening-closing control apparatus including: a driver's seat main switch operated to open and close the window at the driver's seat; a passenger's seat main switch having a third contact operated to close the window at the passenger's seat and a fourth contact operated to open the window at the passenger's seat, the passenger's seat main switch operated to open and close the window at the passenger's seat; a motor current detector configured to detect current flowing to the passenger's seat motor; a first relay circuit unit including a first common relay terminal connected to the first normally closed terminal, a first normally opened relay terminal connected to the positive electrode of the power supply, and a first normally closed relay terminal connected to ground; a second relay circuit unit including a second common relay terminal connected to the second normally closed terminal, a second normally opened relay terminal connected to the positive electrode of the power supply, and a second normally closed relay terminal connected to ground; an operation detector configured to detect operation to the passenger's seat sub switch in accordance with motor current detected by the motor current detector; and an opening-closing controller configured to control the first relay circuit unit and the second relay circuit unit in accordance with the operation to the passenger's seat sub switch; wherein the operation detector detects whether the closing operation or the opening operation is performed to the passenger's seat sub switch in accordance with an amount of the motor current and detects duration of the operation to the passenger's seat sub switch, and wherein the opening-closing controller controls the first relay circuit unit or the second relay circuit unit to execute automatic motion of automatically closing or opening the window at the passenger's seat in accordance with the duration of the operation to the passenger's seat sub switch.
