Automobile active anti-collision system

Abstract

The invention discloses an automobile active anti-collision system, which can reduce the harm to an automobile driver in the sudden unavoidable collision accident. The automobile active anti-collision system includes a control module, a preprocessing module, an execution module, an energy absorbing module and a data acquisition module; the data acquisition module is used for collecting the lane information of a road, the vehicle information, front and rear obstacle information and the relative information of the vehicle and the front and rear obstacles on the lane of the road; the preprocessing module establishes a distribution model of the vehicle and vehicles on the lane of the road under the current status based on the information obtained by the data acquisition module; the control module judges whether collision risk exists or not based on the data processed by the preprocessing module, grades the collision and sends corresponding instructions to the execution module and the energy absorbing module according to different grades so as to reduce avoid collision; the execution module sends out a warning to the driver, and manipulates a brake system and a steering system to execute corresponding operations; and the energy absorbing module is an active ejection and withdrawal 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...

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
