Vehicle-mounted narrow-band wireless communication apparatus and roadside-to-vehicle narrow-band wireless communication system
First Claim
1. A vehicle-mounted narrow-band wireless communication apparatus comprising:
- a wireless communication unit for receiving, through dedicated narrow-band communication, roadside information relating to a junction that is supplied from a roadside communication apparatus having a communication area that covers a part of a geographical area within a predetermined distance of the junction;
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 storing and managing the roadside information from the wireless communication unit and operating condition information from the operating condition detection unit;
an information provision determination unit for determining whether or not warning information can be provided on the basis of the roadside information and the operating condition information obtained from the information storing/managing section;
an HMI output control unit for controlling HMI output on the basis of a determination result from the information provision determination unit and the parameters obtained from the parameter management unit; and
an information provision output apparatus for performing information provision on the basis of an HMI output request transmitted from the HMI output control unit.
