Abstract

The invention provides a vehicle anti-collision method and a vehicle anti-collision system based on an Internet of Vehicles. The vehicle anti-collision method comprises the steps of: acquiring driving data of a current vehicle and vehicles within a certain range of the current vehicle; selecting at least one vehicle as a target vehicle from the vehicles according to the driving data; determining a collision time threshold value of the current vehicle and the target vehicle according to the driving data of the current vehicle, the driving data of the target vehicle and a pre-established judgment model based on an artificial neural network; determining collision time of the current vehicle and the target vehicle according to the driving data of the current vehicle, the driving data of the target vehicle and the pre-established judgment model; and judging whether the collision time is less than or equal to the collision time threshold value, if so, sending a danger signal to a driver of the current vehicle, and warning the driver timely, thereby greatly ensuring the safety of driving.

Description

technical field [0001] The present invention relates to the technical field of automobiles, and more specifically, relates to a vehicle anti-collision method and system based on Internet of Vehicles. Background technique [0002] At present, due to the increasing number of cars on the road and the increasingly complex road conditions, the number of traffic accidents that occur every year is also increasing. According to incomplete statistics, the number of traffic accidents in the country exceeds 500,000 every year, and the death toll exceeds 100,000. Among them, the main cause of traffic accidents is the driver's misjudgment of road condition information or untimely response to emergencies while driving the vehicle. [0003] Based on this, a kind of vehicle anti-collision system applied to automobiles is disclosed in the prior art, such as adaptive cruise system and forward anti-collision system, etc., which mainly adopt sensors such as radar or camera to collect the infor...
