DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiments shown in the accompanying drawings.

FIG. 1 relates to an embodiment of the present invention.
At least antenna 1 for transmitting a predetermined code as a signal
1 is a portable non-contact key having a transmission unit 1 and a transmission unit 12.
A storage unit 13 for storing the code and a control unit 14 for controlling transmission are integrally provided, and are driven by a power supply such as a button battery (not shown). In addition, 15 is a receiving unit for receiving a signal from the outside, and 16 is an antenna for the receiving unit 15.
Can also be used.

Reference numeral 20 denotes a receiving unit installed in the cabin of the vehicle, which includes an antenna 21 and a receiving unit 22 for receiving a signal from the key 10, a storage unit 23 storing a predetermined ID code, The control unit 24 includes, for example, a microcomputer that sends a signal to the door lock motor 30 to open and close the door lock when the signal is determined to be normal by comparing the signal with the code stored in the storage unit 23. are doing. Note that reference numeral 25 denotes a transmitting unit for transmitting a signal to the outside, and reference numeral 26 denotes an antenna for the transmitting unit 25. This antenna 26 can also be used as the antenna 21 for the receiving unit 22.

Reference numeral 40 denotes an audio device as an auditory display device installed in the vehicle interior; 50, a combination meter as a visual display device installed in the vehicle interior;
Is a room lamp, which is a lighting device installed in the interior of the vehicle.
4 is electrically connected.

Next, each pattern relating to the control of the display device performed by the control unit 24 of the receiving unit 20 will be described.

In pattern A, a key such as a driver
0 is artificially operated to transmit a predetermined code as a signal to the transmitting unit 1
2 through the antenna 11, and this signal is received by the receiving unit 22 through the antenna 21, and the control unit 24 compares the signal with a predetermined ID code stored in the storage unit 23,
If it is determined that the door is normal, a signal is sent to the door lock motor 30 to unlock the door. At the same time, the control unit 24 starts the performance of the audio device 40 and the combination meter 50.
One of the start of the check mode and the start of lighting of the room lamp 60 according to the automatic pointer rotation instruction is appropriately selected, that is, the display device is activated.

The pattern B is the same as the pattern A except that the key 10 transmits a predetermined code as a signal at a fixed timing. That is, the display device can be activated in the same manner as in the pattern A, without a user such as a driver operating the key 10 artificially. Specifically, for example, a predetermined signal is transmitted from the transmission unit 25 of the reception unit 20 to the surroundings via the antenna 26 as a request signal, and a user such as a driver is moved from the reception unit 20 (that is, the vehicle) by a predetermined distance. In the case of being located in the range, when the receiving unit 15 of the key 10 receives via the antenna 16, the control unit 14 of the key 10 transmits a predetermined code as a signal from the transmitting unit 12 via the antenna 11 and receives this signal. By receiving the signal via the antenna 21 at the unit 22 and comparing the signal at the control unit 24, the display device can be activated in the same manner as in the pattern A without any manual operation. Note that, even in a configuration in which a predetermined code is always transmitted as a signal from the key 10 at a constant cycle without responding to a request signal from the receiving unit 20, the display device is activated in the same manner as in the pattern A without any manual operation. However, in this case, the load on the power supply of the key 10 is increased, which is not practical.

In the pattern C, the storage unit 13 of the key 10 stores personal information of a user such as a driver instead of storing a predetermined code for locking or unlocking a door. To send. In the case where a plurality of users use one vehicle, for example, by storing personal information with a larger amount of information and using this as a signal instead of storing a predetermined code for simply locking or unlocking a door. ,
If a plurality of keys 10 are individually set for each user, the display device to be activated for each user can be set,
Convenience is improved.

When the display device is activated together with the unlocking of the door, the load on the battery mounted on the vehicle increases because the engine has not been started yet. It is not desirable to continue.

Therefore, if there is no operation related to the vehicle within a predetermined time after the unlocking, it is effective that the control unit 24 stops the activation of the display device.

For example, if there is no door opening operation within a certain period of time after unlocking, the control unit 24 stops the activation of the display device, or starts the engine within a certain period of time after unlocking. If not, the control unit 24 may stop the activation of the display device.

Alternatively, when the voltage of the battery mounted on the vehicle is equal to or lower than a predetermined level, the control unit 24 activates the display device even if it receives a signal from the key 10 and determines that the signal is normal. It is also possible to prohibit.

[0033]

According to the present invention, the control device detects unlocking of the door of the vehicle, and activates a display device such as an auditory display device, a visual display device, or a lighting device installed in the cabin of the vehicle. This makes it possible to easily inform the user of the state of the opening / closing operation of the door lock, thereby reducing the mental burden on the user such as the driver.

Further, by activating the display device before the user such as a driver gets on the vehicle, a new effect which has never been achieved can be exhibited.
