[0002]
[Prior art]
In recent years, so-called keyless door lock devices have become widespread in automobiles with respect to door locks. The keyless type door lock device receives a door lock control signal transmitted from a key switch device by a receiving unit provided on the vehicle side, and based on the signal, an electronic control unit for electric door control (Electrical Control Unit). Control the driving of the door lock device to lock or unlock the door lock device. As such a key switch device, a so-called wireless remote control device and an electronic key device are known.
[0003]
In the case of a wireless remote control device, when a user operates a switch provided on the remote control device, a door lock control signal is transmitted from the remote control device to a reception unit provided on the automobile side, and the door lock device is locked or locked. An unlock is performed.
[0004]
Also, in the case of an electronic key device, a door lock control transmitted from the electronic key device when the user carries the electronic key device away from the vehicle or approaches the vehicle without operating the user. When the signal is no longer received by the receiver provided on the vehicle, the door lock device is locked, and the door lock control signal transmitted from the electronic key device is received by the receiver provided on the vehicle. When the door lock device is unlocked, the door lock device is unlocked.
[0005]
By the way, in such a keyless type door lock device, since the user does not directly operate the door lock device of the automobile, when the surrounding noise is loud, the operation sound of the door lock device by the key switch device is confirmed. It can be difficult to do.
[0006]
For this reason, conventionally, when locking or unlocking the keyless type door lock device, these operations are linked with these door lock / door unlock operations so that these operations can be visually confirmed from the outside. For example, there are known lamps such as a vehicle width light which is turned on and off a different number of times between a locked state and an unlocked state, and the interior light is turned on or off or blinks.
[0007]
In addition, in conjunction with the locking or unlocking operation of the keyless door lock device, for example, a sound warning device such as a dedicated buzzer provided outside the vehicle compartment for the light inside the cover of the tire house is sounded, so that the keyless door lock device is activated. There is also known a device in which the locking or unlocking operation of a locking device can be acoustically confirmed from the outside.
[0008]
However, providing such a dedicated speaker or buzzer as a voice warning device in a door lock response device requires installation space and wiring of the voice warning device, which limits installation and costs. Will be expensive.
[0009]
On the other hand, there is known an anti-theft device that incorporates an alarm generation circuit in an interior light provided on the ceiling of a vehicle compartment and uses an existing horn as an audio warning device to activate the horn when theft occurs. (See Patent Document 1).
