Abstract

The embodiment of the invention provides a vehicle turning reminding method, device and system. The vehicle turning reminding method includes the steps that an Internet of vehicles communication base station intelligently informs the limited speed of a vehicle during turning through a V2X system, the vehicle sends turning information to the base station, and the Internet of vehicles communication base station receives the turning information reported by the vehicle, updates an information database according to the turning information to obtain new speed limit information, and sends the new speed limit information to vehicles in the turning area to accurately remind drivers of different limit speed under different environment when driving vehicles different in models. Vehicle safe turning is realized, safety coefficient is increased, and traffic accidents are prevented.

Description

technical field [0001] Embodiments of the present invention relate to the field of vehicle control, and in particular, to a method and device for prompting vehicle turning. Background technique [0002] With the development of the automobile industry, the number of automobiles is increasing. For drivers, driving safety issues are very important. In the process of driving, the driver usually needs to perceive the situation around the vehicle through vision. The binocular vision limit of human beings is 120 degrees, which is extremely limited. When the vehicle is turning, the actual range that the driver can observe will be smaller, which poses a safety hazard. Therefore, it is stipulated that when vehicles are approaching a turn, they need to pass at a speed limit. [0003] At present, speed limit prompts are designed at the turning places of expressways and road bridges. For example, the speed limit signs of 40KM / h and 20KM / h. On some of the more advanced roads, speed li...
