First Claim
1. A roadside-vehicle cooperative illumination system comprising an in-vehicle apparatus mounted in a vehicle and responsible for controlling a headlight of the vehicle and a roadside apparatus positioned along a roadside and responsible for controlling a road illumination lamp, the headlight and the road illumination lamp being controlled cooperatively through communications between the in-vehicle apparatus and the roadside apparatus, whereinthe in-vehicle apparatus comprises:
- a communication unit that communicates with the roadside apparatus;
a detector that detects information pertaining to operation of the headlight of the vehicle; and
an arbiter that transmits a request to the roadside apparatus for altering at least one of an illuminance and an illumination range of the road illumination lamp on the basis of the information pertaining to operation of the headlight of the vehicle detected by the detector; and
the roadside apparatus comprises;
a communication unit that communicates with the in-vehicle apparatus;
an arbiter that determines whether or not to accept the request from the in-vehicle apparatus side arbiter, and determines at least one of the illuminance and the illumination range of the road illumination lamp on the basis of the determination of whether or not to accept the request from the in-vehicle apparatus side arbiter; and
a controller that controls the road illumination lamp according to the at least one of the illuminance and the illumination range of the road illumination lamp determined by the roadside apparatus side arbiter.

Abstract
A roadside-vehicle cooperative illumination system in which a headlight of a vehicle and a road illumination lamp can be controlled cooperatively through communications between an in-vehicle apparatus and a roadside apparatus. For example, when power consumption of the headlight has to be reduced, an in-vehicle apparatus side arbiter transmits a request to the roadside apparatus for increase illumination of the road illumination lamp. A roadside apparatus side arbiter determines whether or not to accept the request from the in-vehicle apparatus, and a roadside apparatus side controller controls the road illumination lamp according to the determination of the roadside apparatus side arbiter. This enables the road illumination lamp to be controlled cooperatively so that illumination of the road illumination lamp can compensate for deficiencies in illumination of the headlight, which leads to enhancement of vehicle driver'"'"'s convenience and ensuring of safety.
