Description

technical field [0001] The present invention relates to a keyless entry device suitable for, for example, door locking / unlocking control of automobiles, and more particularly to a keyless entry device for interlocking the operation of an automatic window mechanism with the door locking operation. Background technique [0002] Conventionally, as an example of such a keyless door opening device, a passive type keyless door opening device having a vehicle-mounted device mounted on a vehicle and a portable device for wireless communication with the vehicle-mounted device is known as an example of such a keyless door opening device. The remote control device, the vehicle-mounted device has a door locking mechanism for locking / unlocking the car door, an automatic window mechanism for driving the opening and closing of the window, and a microcomputer capable of controlling the door locking mechanism and the automatic window mechanism. The door lock / unlock request signal from the po...

Problems solved by technology

[0005] In the above-mentioned conventional passive type keyless door opening device, when the user with the portable remote control leaves the vehicle, the doors are automatically locked and the windows are automatically closed. Therefore, it is possible to reliably prevent the theft of articles in the vehicle, etc. , for example, when the user parks in hot weather in summer, there is a problem that the temperature inside the car will rise because the car cannot be ventilated

In addition, the user switches the window opening and closing operation using the automatic window mechanism to the manual mode, stops the window with an appropriate gap opened, and if the door is automatically locked after the manual operation, the interior of the vehicle can be ventilated. At this time, since the user must manually open and close the window, there are also problems of cumbersome operation and poor convenience.
