Problems solved by technology

However, the existing active collision avoidance system simply collects the speed and distance of the vehicle in front relative to the vehicle based on the sensor and then calculates whether there is a possibility of collision
When there is a large angle between the two vectors of relative distance and relative speed, the collision judgment will be inaccurate, and the influence of the acceleration of the front vehicle will also be ignored
[0005] The active collision avoidance system of the car also needs a certain amount of execution time. When the car faces a sudden obstacle, the active collision avoidance system may not be able to avoid the collision
Invention patent application for a car anti-collision system (application number, 201510443395.7) can only respond to avoidable collision accidents, but cannot deal with sudden collisions
At present, there is no active collision avoidance system that can reduce and reduce the damage to car drivers caused by sudden unavoidable collision accidents

Abstract

The invention discloses an active automobile anti-collision system, which can reduce and reduce the damage caused to the automobile driver by sudden unavoidable collision accidents. It includes a control module, a pre-processing module, an execution module, a buffering and energy-absorbing module, and a data acquisition module; the data acquisition module is used to collect road lane information, vehicle information, front and rear obstacle information, and the relationship between the vehicle and the front and rear obstacles on the road lane. Relative information; the pre-processing module establishes the current vehicle and road lane vehicle distribution model based on the information obtained by the data acquisition module; the control module determines whether there is a collision risk based on the data processed by the pre-processing module, and classifies the collision into levels. Different levels send corresponding instructions to the execution module and the buffer energy-absorbing module to reduce or avoid collisions; the execution module issues an alert to the driver and simultaneously operates the braking system and steering system to perform corresponding operations; the buffering energy-absorbing module actively pops up and retracts device.

Description

technical field [0001] The invention belongs to the field of automobile safety, and in particular relates to an automobile active collision avoidance system and a protection device in case of sudden collision. Background technique [0002] With the development of electronic technology and Internet technology, modern cars are also developing in the direction of intelligence. Driverless cars have become the goal of auto workers. However, in the process of developing from ordinary cars to driverless cars, intelligent assisted driving cars will inevitably exist for a long time, as a transition from ordinary cars to driverless cars. Active collision avoidance is the most important component of intelligent assisted driving vehicles. It is the guarantee for the safety of future driverless cars. [0003] With the continuous increase of my country's car ownership, traffic accidents are also increasing year by year, causing huge economic and property losses to the society. Accordi...
