2. Description of the Related Art Conventionally, in vehicles such as automobiles, lock/unlock signals from a portable transmitter are received by a receiver on the vehicle body to drive a door lock/unlock mechanism. A so-called keyless entry device that allows doors to be locked and unlocked even from a certain distance outside the vehicle is generally well known (see, for example, Japanese Patent Laid-Open No. 60-37380).

By being equipped with such a keyless entry device, it is possible to lock and unlock the door remotely with a single switch operation on the transmitter side, and locking and unlocking of the door can be performed remotely using a key operation. - Eliminates the hassle of unlocking.

[0004] Furthermore, among the above keyless entry devices, one is known that has a locking/unlocking function for only the driver's door and a locking/unlocking function for all doors. By providing the above two locking/unlocking functions, only the driver's door can be independently locked or unlocked, further improving convenience.

[0005]

[Problems to be Solved by the Invention] By the way, when locking and unlocking the doors using the above keyless entry device, when the driver operates the switch of the transmitter from a certain distance from the vehicle, the door lock knob Since the actual status of the door cannot be visually checked, it is impossible to confirm whether each door is actually locked or unlocked according to the user's will, which may cause anxiety.

[0006] For example, in a keyless entry device, the range in which the receiver can catch signals from the transmitter is usually limited, but it is not clear whether or not the position to which the keyless entry device has performed the lock operation is within this range. In some cases, it may not be possible to determine the Furthermore, due to incorrect switch operation or carelessness, the door may not actually be locked even though the driver intended to lock it. Conventionally, when such a concern arises, it is necessary to go back to the vehicle and check the condition of the door lock knob, which is troublesome.

In particular, in a keyless entry device that has two locking/unlocking functions, one for only the driver's door and the other for all doors, it is not only possible to lock/unlock the doors, but also to lock/unlock all the doors. In some cases, it may be necessary to confirm whether or not an operation has been performed, and it would be extremely convenient if this confirmation could be performed from a location away from the vehicle.

[0008] Accordingly, the present invention has the following advantages: By controlling the operating state of predetermined electrical components in accordance with the locking/unlocking operation of the door,
The purpose of this invention is to provide a keyless entry device that allows you to easily check whether a door is locked or unlocked from a distance.

[0009]

[Means for Solving the Problem] Therefore, the first invention of the present application provides a keyless entry device having a locking/unlocking function for only the driver's door and a locking/unlocking function for all doors. Therefore, when only the driver's door is locked and unlocked, the specified electrical components are controlled to the specified operating state, and when all the doors are locked and unlocked, the electrical components that are different from the above are controlled. It is characterized by controlling other electrical components to a predetermined operating state.

[0010] A second invention of the present application is a keyless entry device having a function of locking/unlocking only the driver's door and a function of locking/unlocking all the doors. When a locking/unlocking operation is performed, the predetermined electrical components are controlled to a predetermined operating state,
When all the doors are locked/unlocked, the electrical components are controlled to be in an operating state different from the operating state described above.

[0011]

According to the first invention of the present application, when the keyless entry device locks and unlocks only the driver's door or locks and unlocks all doors, different electrical components are automatically activated. Since it is controlled to the operating state of
By selecting electrical components whose operating status can be easily confirmed from a remote location outside the vehicle, it is possible to easily confirm the locked/unlocked status of only the driver's door or all doors from a distance. This improves convenience.

According to the second aspect of the present invention, when the keyless entry device locks and unlocks only the driver's door or all doors,
Since the same predetermined electrical components are controlled to different operating states, by selecting electrical components whose operating states can be easily checked from a remote location outside the vehicle, only the driver's door door can be controlled. Alternatively, the locked and unlocked states of the doors for all seats can be easily checked from a distance, improving convenience. Moreover, in this case, the locking/unlocking state can be checked with one electrical component, so the configuration can be simplified.
