Abstract

A keyless entry device includes: a transmitter which includes an operating section relating to a door lock state for transmitting a door operation information and a specific identifying information based on an operating state of the operating section; and a receiving unit for outputting a signal to a door lock device based on the transmitted door operation information when the specific identifying information transmitted coincides with a registered identifying information stored previously; wherein a plurality of pieces of partial informations obtained by dividing the registered identifying information are sequentially received by the receiving unit to permit the information to be stored in the receiving unit.

Claims

1. A keyless entry device, comprising:

a transmitter with an operating section relating to a door lock state for transmitting a door operation information and a specific identifying information based on an operating state of the operating section; and

a receiving unit for outputting a signal to a door lock device based on the transmitted door operation information when the specific identifying information transmitted coincides with a registered identifying information stored previously;

wherein a plurality of pieces of partial informations obtained by dividing the registered identifying information are sequentially received by the receiving unit to permit the registered identifying information to be stored in the receiving unit.

2. The keyless entry device according to claim 1, wherein;

each of the specific identifying information and the registered identifying information includes a number information relating to a number comprising a plurality of digits, and a partial information is the number comprising at least one digit in the number information.

3. The keyless entry device according to claim 2, further comprising a reporting section for reporting that a reception of the partial information by the receiving unit is completed, with respect to each of the plurality of the partial informations.

4. The keyless entry device according to claim 2, further comprising a displaying section for displaying the number information when the registered identifying information is stored in the receiving unit.

5. The keyless entry device according to claim 2, wherein, by operating an operating switch on the transmitter with respect to each digit of the number information, the registered identifying information to be stored in the receiving unit is decided.

6. The keyless entry device according to claim 5, wherein the transmitter holds the registered identifying information and determines whether the partial information inputted from the operating switch coincides with the partial information of the registered identifying information held by the transmitter.

7. The keyless entry device according to claim 5, wherein the operating switch uses a button system and a figure of each digit of the number information is decided on the basis of a number of times of pressing the operating switch.

8. The keyless entry device according to claim 5, wherein the operating switch uses a button system and a figure of each digit of the number information is decided on the basis of a time period of holding on the operating switch.

9. The keyless entry device according to claim 7, wherein the operating switch comprises a figure changing button for changing the figure of each digit and a figure deciding button for deciding the figure of each digit.

10. The keyless entry device according to claim 1, wherein the receiving unit is so structured that storing the registered identifying information is permitted when a predetermined registration permission signal is received.

11. The keyless entry device according to claim 1, wherein a customized information is stored when the registered identifying information is stored in the receiving unit.

12. A keyless entry device comprising:

a transmitter with an operating section relating to a door lock state for transmits a door operation information and a specific identifying information based on an operating state of the operating section;

a receiving unit for outputting a signal to a door lock device based on the transmitted door operation information when the specific identifying information transmitted coincides with registered identifying information stored previously; and

an operating switch installed in a vehicle and connected to the receiving unit;

wherein the registered identifying information is stored in the receiving unit based on an operating state of the operating switch.

13. The keyless entry device according to claim 12, wherein each of the specific identifying information and the registered identifying information includes a number information relating to a number comprising a plurality of digits, and by operating the operating switch with respect to each digit of the number, the registered identifying information to be stored in the receiving unit is decided.

14. The keyless entry device according to claim 13, wherein the operating switch uses a button system and a figure of each digit of the number information is decided on the basis of a number of times of pressing the operating switch.

15. The keyless entry device according to claim 13, wherein the operating switch uses a button system and a figure of each digit of the number information is decided on the basis of a time period of holding on the operating switch.

16. The keyless entry device according to claim 13, wherein the operating switch comprises a digital figure designating switch for designating a figure of each digit of the number information and a digital figure deciding switch for deciding the figure designated by the digital figure designating switch.

17. The keyless entry device according to claim 12, wherein the registered identifying information is stored in the receiving unit based on the operating state of the operating switch and based on a registered identification signal transmitted from a failure diagnosing device provided separately of the vehicle and diagnoses failures of the receiving unit.

18. The keyless entry device according to claim 12, wherein the operating switch is installed in the vehicle for operating a door to enter a locked state or an unlocked state, and when the registered identifying information is stored by an operation on the operating switch, an output of a control signal for controlling the door lock device to enter the locked state or the unlocked state in conjunction with the operating switch is stopped.

20. The keyless entry device according to claim 12, wherein the receiving unit is so structured that storing the registered identifying information is permitted when a predetermined registration permission signal is inputted.

22. The keyless entry device according to claim 12, further comprising a displaying section for displaying the number information when the registered identifying information is stored in the receiving unit.

24. The keyless entry device according to claim 12, wherein when the registered identifying information is stored in the receiving unit, a customized information is stored along with the registered identifying information.

19. A keyless entry device comprising:

a transmitter with an operating section relating to a door lock state for transmitting a door operation information and a specific identifying information based on an operating state of the operating section; and

a receiving unit for outputting a signal to a door lock device based on the transmitted door operation information when the specific identifying information transmitted coincides with registered identifying information stored previously;

wherein the registered identifying information is stored in the receiving unit based on a registered identification signal transmitted from a failure diagnosing device provided independently of a vehicle and diagnoses failures of the receiving unit.

21. The keyless entry device according to claim 19, wherein the receiving unit is so structured that storing the registered identifying information is permitted when a predetermined registration permission signal is inputted.

23. The keyless entry device according to claim 21, further comprising a displaying section for displaying the number information when the registered identifying information is stored in the receiving unit.

25. The keyless entry device according to claim 23, wherein when the registered identifying information is stored in the receiving unit, a customized information is stored along with the registered identifying information.
