Abstract

When a vehicle and a smartphone are in a second communication state, the vehicle can operate, and then if the vehicle and the smartphone are not in the second communication state for a predetermined time or longer, and if a main switch of the vehicle detects a predetermined operation, an emergency advertising is transmitted from the vehicle. Thereby, the smartphone can be used as a key that can receive the emergency information from the vehicle. By enabling the smartphone to be used as a key for the vehicle, it is possible to popularize a smartphone that can be used as a key for the vehicle.

Claims (50)

1. A wireless communication system, comprising:

a vehicle including an operation unit and a first wireless communication circuit conforming to a first wireless method;

a first wireless communication terminal including a second wireless communication circuit conforming to the first wireless method and available to communicate with the first wireless communication circuit; and

a second wireless communication terminal including a third wireless communication circuit conforming to the first wireless method and available to communicate with the first wireless communication circuit, and a fourth wireless communication circuit conforming to a second wireless method different from the first wireless method, wherein

when the first wireless communication circuit of the vehicle and the second wireless communication circuit of the first wireless communication terminal are in a first communication state, the vehicle becomes operable,

when the first wireless communication circuit of the vehicle and the third wireless communication circuit of the second wireless communication terminal are in a second communication state, the vehicle becomes operable, and

after the first wireless communication circuit of the vehicle and the third wireless communication circuit of the second wireless communication terminal are in the second communication state, if the first wireless communication circuit and the third wireless communication circuit do not enter into the second communication state for a predetermined time or longer, and if the operation unit of the vehicle detects a predetermined operation, the first wireless communication circuit of the vehicle transmits a packet including emergency information.

2. The wireless communication system according to claim 1 , wherein

even when the first wireless communication circuit of the vehicle and the second wireless communication circuit of the first wireless communication terminal are in the first communication state, after the first wireless communication circuit of the vehicle and the third wireless communication circuit of the second wireless communication terminal enter into the second communication state, if the first wireless communication circuit and the third wireless communication circuit do not enter into the second communication state for the predetermined time or longer, and if the operation unit of the vehicle detects the predetermined operation, the first wireless communication circuit of the vehicle transmits the packet including the emergency information.

3. The wireless communication system according to claim 1 , wherein

the first wireless communication terminal does not include a wireless communication circuit conforming to the second wireless method.

4. The wireless communication system according to claim 1 , wherein

the second wireless communication terminal is configured to stop at least the third wireless communication circuit from entering into the second communication state via the fourth wireless communication circuit.

5. The wireless communication system according to claim 1 , wherein

the first wireless method is Bluetooth (registered trademark).

6. The wireless communication system according to claim 1 , wherein

the second wireless method is cellular.

7. The wireless communication system according to claim 1 , wherein

8. The wireless communication system according to claim 7 , wherein

in the authentication function of the second wireless communication terminal, if the authentication is successful, at least the third wireless communication circuit continues to be in the second communication state, and if the authentication fails, at least the third wireless communication circuit stops entering into the second communication state.

9. The wireless communication system according to claim 1 , wherein

at least the second wireless communication terminal is registerable in the vehicle.

10. The wireless communication system according to claim 1 , wherein

the first communication state and the second communication state are the same.

11. A wireless communication device mountable on a vehicle including an operation unit, comprising:

a first wireless communication circuit conforming to a first wireless method, wherein

the wireless communication device is able to be communicated with a first wireless communication terminal, the first wireless communication terminal including a second wireless communication circuit conforming to the first wireless method and available to communicate with the first wireless communication circuit,

the wireless communication device is able to be communicated with a second wireless communication terminal, the second wireless communication terminal including a third wireless communication circuit conforming to the first wireless method and available to communicate with the first wireless communication circuit, and a fourth wireless communication circuit conforming to a second wireless method different from the first wireless method,

when the first wireless communication circuit and the second wireless communication circuit of the first wireless communication terminal are in a first communication state, the vehicle becomes operable,

when the first wireless communication circuit and the third wireless communication circuit of the second wireless communication terminal are in a second communication state, the vehicle becomes operable, and

after the first wireless communication circuit and the third wireless communication circuit of the second wireless communication terminal are in the second communication state, if the first wireless communication circuit and the third wireless communication circuit do not enter into the second communication state for a predetermined time or longer, and if the operation unit of the vehicle detects a predetermined operation, the first wireless communication circuit transmits a packet including emergency information.

12. The wireless communication device according to claim 11 , wherein

even when the first wireless communication circuit and the second wireless communication circuit of the first wireless communication terminal are in the first communication state, after the first wireless communication circuit and the third wireless communication circuit of the second wireless communication terminal enter into the second communication state, if the first wireless communication circuit and the third wireless communication circuit do not enter into the second communication state for the predetermined time or longer, and if the operation unit of the vehicle detects the predetermined operation, the first wireless communication circuit transmits the packet including the emergency information.

13. The wireless communication device according to claim 11 , wherein

the first wireless communication terminal does not include a wireless communication circuit conforming to the second wireless method.

14. The wireless communication device according to claim 11 , wherein

the second wireless communication terminal is configured to stop at least the third wireless communication circuit from entering into the second communication state via the fourth wireless communication circuit.

15. The wireless communication device according to claim 11 , wherein

the first wireless method is Bluetooth (registered trademark).

16. The wireless communication device according to claim 11 , wherein

the second wireless method is cellular.

17. The wireless communication device according to claim 11 , wherein

the second wireless communication terminal has at least one authentication function of password authentication, fingerprint authentication, and face authentication.

18. The wireless communication device according to claim 17 , wherein

in the authentication function of the second wireless communication terminal, if the authentication is successful, at least the third wireless communication circuit continues to be in the second communication state, and if the authentication fails, at least the third wireless communication circuit stops entering into the second communication state.

19. The wireless communication device according to claim 11 , wherein

at least the second wireless communication terminal is registerable in the wireless communication device.
