A signal information providing system and a generation control method are provided. Provided is a technique for ensuring the security of communication disconnection in a mechanism for providing information relating to a signal display relating to an intersection to a vehicle having a function of automatic driving or auxiliary driving. A signal information provision system (1) transmits, for different crossing roads related to an intersection, signal time information for the different crossing roads, the signal time information including a signal change time for one period and a next display stop start time for the one period. The stop display start time is a time at which a change is made to stop display, and the signal time information of the different intersection road does not include a change time of the signal at a future time compared with the next stop display start time. The vehicle (30) compares the change time included in the received signal time information with the current time, and determines the display of the intersection relating to the path of travel of the vehicle.

    提供一种信号信息提供系统和生成控制方法。提供用于在向具有自动驾驶或辅助驾驶的功能的汽车提供与交叉口有关的信号显示的信息的机制中实现针对通信断开的安全性的确保的技术。信号信息提供系统(1)按与交叉口有关的不同交叉道路来发送不同交叉道路的信号时刻信息,该不同交叉道路的信号时刻信息包含一个周期量的信号的变化时刻和该一个周期的下一个停止显示开始时刻,该停止显示开始时刻是变化为停止显示的时刻,该不同交叉道路的信号时刻信息不包含与该下一个停止显示开始时刻相比为未来时刻的信号的变化时刻。汽车(30)将所接收到的信号时刻信息中包含的变化时刻与当前时刻进行比较,来判断与本车的行进路径有关的交叉口的显示。
