[0003] However, in the above-mentioned conventional systems, the scope of providing information on abnormal parts is limited.
Therefore, even if the content of the abnormality is related to abnormal driving, the surrounding vehicles and pedestrians of the platooning vehicles cannot know the occurrence of the abnormality.

The invention relates to a signal lamp management system and a signal lamp management method. A signal lamp management system for managing signal display of signal lamps includes a communication device, a control device, and a map database. The control device performs emergency control of signal display when abnormal travel information indicating information of a vehicle traveling abnormally is included in information from a communication vehicle. In the emergency control, the control device predicts a future trajectory of the vehicle traveling abnormally on the basis of the abnormal traveling information. Next, the control device generates, on the basis of the map information and the future track, an emergency control signal, which is a signal for temporarily prohibiting passage at intersections and crosswalks on roads along the future track. The control device then transmits the emergency control signal to the control target signal lamp. The signal lamp to be controlled refers to a signal lamp at an intersection and a pedestrian crosswalk on a road along a future track.
Description
technical field [0001] The present invention relates to a system and method for managing the signal display of a signal light. Background technique [0002] Japanese Patent Laid-Open No. 2019-87076 discloses a system including a plurality of vehicles that travel in a platoon and a server that communicates with these vehicles individually. The server of this conventional system detects an abnormal vehicle among a plurality of vehicles based on the behavior information of each vehicle. Detection of abnormal vehicles is performed based on statistical processing of behavior information. In a case where an abnormal vehicle is detected, the server determines an abnormal location based on behavior information of the abnormal vehicle received from a normal vehicle traveling in front of or behind the abnormal vehicle. The determination of the abnormal part can also be performed by V2V (Vehicle to Vehicle: vehicle-to-vehicle communication) between the abnormal vehicle and the normal...
