Abstract

A vehicle receiver registers unique IDs of a plurality of portable transmitters in memory regions of a vehicle internal memory, and the plurality of portable transmitters registers each unique ID in a memory region of each portable internal memory. During a period for which an operation mode of the vehicle receiver is changed to a registration mode, when a predetermined operation member of the portable transmitter is operated according to a predetermined operation aspect, the IDs are transmitted to the vehicle receiver and are sequentially written in memory regions of the vehicle internal memory.

Claims

1. A remote keyless entry device including a plurality of portable transmitters and one vehicle receiver, the respective portable transmitters transmitting an instruction signal including a unique ID assigned to each portable transmitter to the vehicle receiver as a wireless signal, the vehicle receiver controlling and driving a controlled member mounted on a vehicle according to the instruction signal when the vehicle receiver receives the wireless signal and confirms that the ID included in the instruction signal is the same as one of IDs stored in an internal memory of the vehicle receiver,

wherein the plurality of portable transmitters store the unique IDs in memory regions of portable internal memories, respectively,

the vehicle receiver stores the unique IDs of the plurality of portable transmitters in respective memory regions of the vehicle receiver internal memory, and

during a period for which an operation mode of the vehicle receiver is set to a registration mode in which a unique ID of a portable transmitter is written and registered in each memory region of the vehicle receiver internal memory, when a predetermined operation member of any one of the plurality of portable transmitters is operated according to a predetermined operation aspect, the ID stored in the portable internal memory of the portable transmitter is read out, the read out ID is repeatedly transmitted to the vehicle receiver a designated number of times, and the ID is sequentially written in respective memory regions of the vehicle receiver internal memory.

3. The remote keyless entry device according to claim 1,

wherein when the predetermined operation member is operated according to the predetermined operation aspect, the portable transmitter further performs an operation for designating the number of times of writing the unique ID, and

when the corresponding unique ID is written in the memory regions of the vehicle receiver internal memory, the vehicle receiver makes the unique ID repeatedly written in the memory regions by the designated number of times of writing the unique ID.

2. A remote keyless entry device including a plurality of portable transmitters and one vehicle receiver, the respective portable transmitters transmitting an instruction signal including a unique ID assigned to each portable transmitter to the vehicle receiver as wireless signal, the vehicle receiver controlling and driving a controlled member for vehicle according to the instruction signal when the vehicle receiver receives the wireless signal and confirms that the ID included in the instruction signal is the same to an ID stored a first memory region of an internal memory of the vehicle receiver,

wherein the plurality of portable transmitters stores the unique IDs in memory regions of portable internal memories, respectively,

the vehicle receiver stores the unique IDs of the plurality of portable transmitters in the first memory region of the vehicle internal memory, and

during a period for which an operation mode of the vehicle receiver is set to a registration mode in which a unique ID of a portable transmitter is written and registered in the vehicle internal memory, when a predetermined operation member installed in the vehicle is operated according to a predetermined operation aspect, the unique ID assigned to the portable transmitter is read out from a second memory region of the vehicle receiver internal memory, and the ID is sequentially written in the first memory region of the vehicle receiver internal memory.

4. The remote keyless entry device according to claim 2,

wherein the vehicle receiver includes an instruction unit for instructing to write the IDs written in the second memory region in the first memory region, and

when the unique ID is written in the memory region of the vehicle receiver internal memory, the unique ID is repeatedly written in the memory region by the number of times designated by the instruction unit.

5. A keyless entry device including a plurality of portable transmitters and one vehicle receiver, the respective portable transmitters transmitting an instruction signal including a unique ID assigned to each portable transmitter to the vehicle receiver as a wireless signal, the vehicle receiver controlling and driving a controlled member for a vehicle according to the instruction signal when the vehicle receiver receives the wireless signal and confirms that the ID included in the instruction signal is the same as any one of IDs stored in an internal memory of the vehicle receiver,

wherein the plurality of portable transmitters store the unique IDs in memory regions of portable internal memories, respectively,

the vehicle receiver stores the unique IDs of the plurality of portable transmitters in respective memory regions of the vehicle receiver internal memory, and

during a period for which an operation mode of the vehicle receiver is set to a registration mode in which a unique ID of a portable transmitter is written and registered in each memory region of the vehicle receiver internal memory, when a predetermined operation member provided in any one of the portable transmitters or a predetermined operation member provided in the vehicle is operated according to a predetermined operation aspect, a random ID different from the unique ID of the portable transmitter is sequentially written in respective memory regions of the vehicle internal memory by the designated number of times, and

when an operation member different from the operation member is operated according the operation aspect or the operation member is operated according to an operation aspect different from the operation aspect, the unique ID of the portable transmitter is written in the vehicle receiver internal memory.
