Abstract
An in-vehicle terminal device includes: a wireless LAN communication section capable of performing wireless communication over a short range; a cellular communication section capable of performing wireless communication over a longer range than the wireless LAN communication section; and a communication method selection section which selects the wireless LAN communication section or the cellular communication section according to a real-time communication requirement for data to be transmitted to or received from outside of a vehicle.
Claims9
An in-vehicle communication device to be installed in a vehicle, comprising:
- a short-range communicator configured to perform wireless communication with a first access point over a first range;
- a long-range communicator configured to perform wireless communication with a second access point over a second range longer than the first range;
- a memory that stores therein a level of a real-time communication requirement of each of different types of data in association with of the types of data, the data comprising probe or accident information to be transmitted from the vehicle and traffic or weather information to be received by the vehicle, said information being associated with a higher level than data other than said information;
- and
- a communication selector configured to select the short-range communicator or the long-range communicator to perform the wireless communication according to said each level of the real-time communication requirement for the data to be transmitted to or received from the first or second access point outside of the vehicle,
- wherein the communication selector selects the long-range communicator to perform the wireless communication of the probe or accident information and the traffic or weather information.
An in-vehicle data-transmission device to be installed in a vehicle, comprising:
- a short-range data-transmitter to perform wireless transmission of data to a first access point from the vehicle over a first range;
- a long-range data-transmitter configured to perform wireless transmission of data to a second access point from the vehicle over a second range longer than the first range;
- and
- a data-transmission selector configured to select the short-range data-transmitter or the long-range data-transmitter to perform the wireless transmission according to a real-time communication requirement for the data to be transmitted to the first or second access point outside of the vehicle,
- wherein the data to be transmitted comprises accident information related to the vehicle, which has a higher level of the real-time communication requirement than other data such that the data-transmission selector selects the long-range data-transmitter to transmit the accident information.
