In-vehicle apparatus and obstacle report system
First Claim
1. An in-vehicle apparatus in a vehicle communicating with a road management apparatus, the in-vehicle apparatus comprising:
- an in-vehicle communicator that receives, from the road management apparatus, (i) obstacle existence or nonexistence information, and (ii) traffic signal information,the obstacle existence or nonexistence information indicating an existence of an obstacle that exists in a designated range containing a crosswalk around an intersection and/or a crosswalk-adjacent area that is adjacent to the crosswalk around the intersection, and further distinguishing an obstacle in the crosswalk and an obstacle in the crosswalk-adjacent area from each other,the traffic signal information containing a currently indicating color of a traffic signal corresponding to the crosswalk; and
a report processing section that executes a report with respect to an obstacle around the intersection to a driver of the vehicle, the report processing section being further configured to suppress a report of an existence of an obstacle that is indicated by the obstacle existence or nonexistence information, which is received via the in-vehicle communicator, based on current traffic signal information contained in the traffic signal information received via the in-vehicle communicator, whereinthe report processing section suppresses the report of the obstacle in the crosswalk-adjacent area from the obstacles indicated in the received obstacle existence or nonexistence information based on the received current traffic signal information.

Abstract
In a left-hand traffic rule, a subject vehicle turns right at an intersection and then passes over a crosswalk, which is corresponded to by a pedestrian-use traffic signal. When the pedestrian-use traffic signal presents a green color as a currently indicating signal color, an obstacle report range is designated as covering both an area A and an area B so as to report an existence of an obstacle. In contrast, when the pedestrian-use traffic light presents a red color as a currently indicating signal color, an obstacle report range is designated as covering only the area A during a red light elapsed time ranging greater than a first marginal time and less than a time, which is obtained by subtracting a second marginal time from a red light cycle time.

16. An obstacle report system including a road management apparatus provided for an intersection, and an in-vehicle apparatus mounted in a vehicle to receive information transmitted from the road management apparatus,
the road management apparatus comprising: -
an obstacle detection section to detect an obstacle in a designated range containing (i) a crosswalk around an intersection, and/or (ii) a crosswalk-adjacent area that is adjacent to the crosswalk around the intersection; a traffic signal information acquisition section to acquire traffic signal information containing a currently indicating signal color of a traffic signal corresponding to the crosswalk; and a transmission section to transmit (i) obstacle existence or nonexistence information that indicates an existence of an obstacle detected by the obstacle detection section and (ii) traffic signal information acquired by the traffic signal information acquisition section, the in-vehicle apparatus comprising; an in-vehicle communicator to receive (i) obstacle existence or nonexistence information, which is received from the obstacle detection section via the transmission section of the road management apparatus, and (ii) traffic signal information, which is received from the traffic signal information acquisition section via the transmission section of the road management apparatus; and a report processing section to execute a report of an obstacle indicated in the obstacle existence or nonexistence information, which is received from the obstacle detection section via the in-vehicle communicator, to a driver of the vehicle, the report processing section being further configured to suppress the report of the obstacle based on current traffic signal information contained in the traffic signal information via the in-vehicle communicator, wherein the obstacle existence or nonexistence information distinguishes an obstacle in the crosswalk and an obstacle in the crosswalk-adjacent area from each other, and the report processing section suppresses the report of the obstacle in the crosswalk-adjacent area out of the obstacles indicated in the received obstacle existence or nonexistence information based on the received current traffic signal information.
