Description

  The present invention relates to a vehicle window opening / closing device suitable for being applied to vehicles such as passenger cars, trucks, and buses.

  In recent vehicles, in order to further improve user convenience, the user approaches a detection area formed by transmission antennas installed at a plurality of locations on the vehicle side, approaching the vehicle with a smart key. In this case, the smart key receives the request signal transmitted by the transmitting antenna based on the control of the in-vehicle device, the smart key transmits the answer signal including the authentication code to the in-vehicle device, and the in-vehicle device answers Introduced a so-called smart entry system that locks and unlocks the door of the vehicle when the authentication code included in the signal is authenticated and when the user touches the touch sensor provided on the door of the vehicle. Has been.

As a system to which such a smart entry system is applied, there is a system described in Patent Document 1, for example. In such a system, when the door is unlocked, the windows of the front, rear, left and right doors of the vehicle are closed, when the door is locked, the windows are opened, and when it is raining, the windows are kept closed. It is proposed to open the window when it is not raining, and to open the window if the temperature in the passenger compartment is higher than the predetermined value, and to keep the window closed if the temperature is lower than the predetermined value. ing.
Japanese Patent No. 2815367

  In the prior art described in Patent Document 1, the above-described control is mainly executed to prevent the window from being closed in advance after getting off to prevent theft, and to consider both the rainfall situation and the temperature in the passenger compartment. In a situation where the vehicle interior is hot in a high temperature state, the user once enters the vehicle interior, opens the door window of the vehicle to ventilate the air in the vehicle interior, turns on the cooling, The troublesomeness of starting operation after lowering the temperature in advance is to be eliminated as much as possible.

  However, in the related art described in Patent Document 1, a case where the parking area where the vehicle is parked is an area that frequently goes back and forth even when the user does not aim to drive the vehicle on a daily basis. Even when the user has a smart key and approaches the parking area without aiming to drive the vehicle, the above-described control that always opens and closes the window as appropriate is executed. There is a problem that the battery is wasted and the user feels uncomfortable.

  Furthermore, the mode of the air conditioner installed in the vehicle is not taken into consideration when the user got off the previous time, and the mode that was finally selected at the time of getting off was the inside air circulation. In such a case, the air in the duct constituting the air conditioner is also in a high temperature state, and there is a problem that the hot air is blown out from the air conditioner immediately after getting into the vehicle.

  In view of the above problems, an object of the present invention is to provide a vehicle window opening / closing device that can perform opening / closing of a vehicle window according to a user's request based on more detailed condition settings.

In order to solve the above problems, a first vehicle window opening and closing device according to the present invention is
