Vehicle forward collision early warning system

Abstract

The invention provides a vehicle forward collision early warning system that comprises a forward-looking camera, at least four distance sensors, a vehicle-mounted processor and an alarm device. According to the vehicle forward collision early warning system, due to the fact that the four distance sensors are arranged, the position where a vehicle head collides with an obstacle in front can be accurately prejudged, and then accurate collision early warning can be given to a driver; as the four distance sensors are opened only when needed, energy is saved; due to the fact that a machine learningmodule is additionally arranged, system false alarms caused by fallen leaves, branches and other obstacles which do not affect driving safety can be avoided, and the confidence coefficient of the early warning system is improved.

Description

technical field [0001] The invention relates to the field of safe driving, in particular to a vehicle forward collision warning system. Background technique [0002] Collisions are the main cause of traffic accidents. Whether it is a car-to-car collision, a car-non-motor vehicle collision or a car-to-person collision, there will be losses. The light ones will pay a certain amount of economic loss and time loss, and the serious ones will cause car crashes and death, which is beyond regret. According to statistics, if the warning can be issued 0.6 seconds in advance, more than 60% of traffic collision accidents can be reduced; if the warning can be issued 1.5 seconds in advance, more than 90% of traffic collision accidents can be reduced. [0003] As a result, the anti-collision function has attracted a lot of attention in the industry, and some products based on visual perception and lidar detection have been launched, and have entered the pre-installation market successivel...
