Vehicle-mounted narrow-band wireless communication apparatus and roadside-to-vehicle narrow-band wireless communication system

A vehicle-mounted narrow-band wireless communication apparatus comprising:

• a first external interface unit for communicating with a wireless communication apparatus in accordance with a predetermined communication protocol;
• a second external interface unit for communicating with an information provision output apparatus in accordance with a predetermined communication protocol;
• an operating condition detection unit for detecting an operating condition of a host vehicle;
• a parameter management unit for managing parameters relating to an HMI;
• information storing/managing section for managing travel assistance information obtained from the first external interface unit and host vehicle information obtained from the operating condition detection unit;
• one or more information provision determination unit for determining whether or not information can be provided on the basis of the information managed by the information storing/managing section;
• and
• an HMI output control unit for controlling HMI output on the basis of a determination result from the information provision determination unit and environment information relating to a junction neighbourhood obtained from the parameter management unit,
• wherein the HMI output control unit outputs an HMI output request to the information provision output apparatus by using the second external interface unit.
