When the notification signal output time determination means 55E determines that the notification time has been reached, the output of the notification signal from the notification signal output means 55C is stopped, so that, for example, the engine during idling is forcibly stopped during this notification time. By setting the time according to the timing,
It is possible to prevent the useless operation of continuously outputting the notification signal even after the engine is forcibly stopped.

Further, according to the in-vehicle device for a keyless entry system of the present invention as defined in claim 9, an operation command signal output from the key device 3 in response to a switch operation in the operation switch group 33A of the key device 3. Is received during the output of the notification signal, the output of the notification signal from the notification signal output means 55C is stopped. Therefore, for example, when the key device 3 outputs an alarm based on the notification signal,

Further, according to the keyless entry system of the present invention as set forth in claim 10, the signal receiving means 37 of the key device 3 receives the notification signal output from the notification signal output means 55C of the in-vehicle device 5. Then, the notification means A of the key device 3 is activated. Therefore, the in-vehicle device 5
The engine start switch 3 included in the key device 3
Third elapsed time measuring means 55 started by operation 3c
Second idling time determination means 5 based on the measured time of A
5B is interlocked with determining that the elapsed time since the engine is automatically started without using the key 31 has reached the predetermined idling time required for idling of the engine. By activating the means A, it becomes possible to reliably inform the driver outside the vehicle that the idling state started without using the key 31 has continued longer than necessary.

According to the keyless entry system of the present invention as set forth in claim 11, the on-vehicle device 5 automatically starts the engine of the vehicle upon receiving the keyless start command signal from the key device 3 in response to the operation of the engine start switch 33c. After that, the normal starting operation detecting means 55F of the in-vehicle device 5
When the normal starting operation of the vehicle engine using the key 31 of the key device 3 is detected, the notification signal output means 5 of the in-vehicle device 5
The output of the notification signal from 5C is stopped. Therefore, for example, by the output of the notification signal from the vehicle-mounted device 5 and the operation of the notification means A of the key device 3 when the notification signal is received by the signal receiving means 37, the idling state started without using the key 31 is changed. The driver outside the vehicle, who recognizes that the operation has continued longer than necessary, performs a normal engine starting operation using the key 31 of the key device 3, and the engine idling is performed by pressing the key 31.
At the time of shifting from the state of automatic starting without using the key 31 to the state of normal starting using the key 31, the output of the notification signal from the vehicle-mounted device 5 and the key device 3 receiving this notification signal by the signal receiving means 37 It becomes possible to return to the normal state by stopping the operation of the notification means A together. In addition, as the key device 3 of the keyless entry system of the present invention described in claim 10 and claim 11,
The key device 3 described in 3, 4, 5 or 6 can be used.

Similarly, in the keyless entry system 1 of the first embodiment, even after the alarm buzzer 38 and the vibrator 39 of the key device 3 are actuated until the elapsed time Ta reaches the engine forced stop time T3, the engine stop switch is also used. The configuration is such that the operations of the switches 33a to 33c and 33e to 33g of the key device 31 except for 33d are ignored.

Therefore, during operation of the alarm buzzer 38 and the vibrator 39, the driver who notices the alarm sounds and vibrations of the alarm buzzer 38 and the vibrator 39 stops the engine start switch 33c and the engine stop in order to stop the operation of the alarm buzzer 38 and the vibrator 39. When the switches 33a, 33b, 33e to 33g of the key device 31 excluding the switch 33d are operated, it is possible to prevent the keyless operation corresponding to the switches from being unnecessarily performed on the vehicle side.

Incidentally, in the above-described first embodiment, after the elapsed time Tb reaches the predetermined time T5 and before the elapsed time Ta reaches the engine forced stop time T3,
When the normal start operation is performed in the vehicle, the vehicle-mounted device 5 wirelessly sends an idling stop signal to the key device 3 via the signal transmitter / receiver 53 to notify the key device 3 that idling has ended. At the same time, the vehicle-mounted device 5 may be configured to stop measuring the elapsed time Ta from the start of the engine.

In the first embodiment, the elapsed time T
Two types of signals, a notification signal and a notification stop signal, are wirelessly transmitted from the vehicle-mounted device 5 when a reaches a predetermined time T1 and thereafter, when the elapsed time Tb reaches a certain time T3. did. However, the form of the notification signal used to notify the idling continuation state of the engine by keyless starting is not limited to the two types of signals as in the first embodiment. For example, the elapsed time Ta is the predetermined time T.
