Abstract
An in-vehicle device has a calculator which obtains subject vehicle information, detects a vehicle in a preset range based on a detection signal from a laser radar for obtaining a vehicle detection result, obtains a curvature of a road, and determines whether the curvature of the road is equal to or smaller than a threshold. If the radius is less than the threshold, a packet having data regarding the subject vehicle information, range position information, and vehicle presence information is generated. If the radius exceeds the threshold, a packet having data regarding the subject vehicle information is generated. The generated packet is then transmitted to an outside of a subject vehicle.
