Abstract:
1. A safety urging system for a self-propelled vehicle, comprising: an on-vehicle communication unit which communicates with roadside communication equipment provided in a predetermined communication area on a road where a vehicle travels, and inputs information about traffic condition in the communication area; a safety urging information output unit which outputs information to urge a driver of the own vehicle to drive safely based on the information obtained by the on-vehicle communication unit; an on-vehicle computation controller which controls operations of the safety urging information output unit and the on-vehicle communication unit; and a communication availability information storing unit which previously stores communication availability information indicating whether communication by the on-vehicle communication unit with the roadside communication equipment is possible, together with map information including the communication area, wherein the on-vehicle computation controller includes: a communication availability recognizing function, activated when the own vehicle reaches near the communication area, to determine whether communication between the on-vehicle communication unit and the roadside communication equipment is possible based on communication availability information, and an operation instruction output function, activated when communication with the roadside communication equipment is impossible, to send an operation instruction to the safety urging information output unit.
