Risk early warning control method for autonomous vehicle and intelligent network connection system

Abstract

The embodiment of the invention discloses a risk early warning control method for an automatic driving vehicle and an intelligent network connection system. The method comprises the steps: a plurality of automatic driving vehicles carry out real-time interaction on the position and speed of each automatic driving vehicle; any automatic driving vehicle calculates forward collision time between the vehicle and the front vehicle and backward collision time between the vehicle and the rear vehicle in real time according to the positions and speeds of the vehicle, the front vehicle and the rear vehicle; if the forward collision time and/or the backward collision time are/is larger than or equal to a preset collision time threshold value, the vehicle sends an early warning prompt to the front vehicle and/or the rear vehicle; after the front vehicle and/or the rear vehicle receives the early warning prompt, the speed is adjusted according to the safety state of the front vehicle and/or the rear vehicle; and the vehicle adjusts the speed of the vehicle according to the adjustment result of the front vehicle and/or the rear vehicle. According to the embodiment of the invention, road network risk control is realized through mutual communication between the autonomous vehicles.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of intelligent networked vehicles, and in particular to a risk warning control method and an intelligent networked system for autonomous vehicles. Background technique [0002] With the continuous development of autonomous driving technology, there are more and more autonomous vehicles. Since the driving rules of autonomous vehicles are different from the driving habits of drivers of human-driven vehicles, the risk warning and control between autonomous vehicles is also significantly different from that of human-driven vehicles. [0003] In the existing technology, the risk warning control of autonomous vehicles is mostly realized through the control center outside the vehicle. The driving parameters of each vehicle are adjusted through the control center to form a centralized road network control system. The performance requirements of the equipment in the center are very high, wh...
