Traffic safety auxiliary control method and system thereof

Abstract

The invention provides a traffic safety auxiliary control method and a traffic safety auxiliary system and belongs to the field of automobile safety. The invention can detect the safe distance between an automobile with the system and an automobile in the front in real time, timely prompt a driver by voice, and control the automobile to operate in an forced manner if necessary; and in overtaking, the invention can calculate the overtaking safe distance in real time, prompts the driver to carry out overtaking or not, and controls the automobile to operate in the forced manner if necessary, so that the vehicle safety is greatly ensured. The traffic safety auxiliary system consists of a signal acquisition unit, a signal amplification and shaping unit, a processor unit and an actuator unit; the traffic safety auxiliary system is communicated with an anti-locked braking system, an electronic steering column lock, an electronic power-assisted steering system and an automobile body control system through a vehicle bus.

Description

technical field [0001] The invention belongs to the field of automobile safety, and relates to a method and a system for improving safety during vehicle running. Background technique [0002] As we all know, when a car is running at high speed, the safety distance between the front car and the rear car increases with the increase of speed. However, the driver sometimes underestimates or deviates from the speed and safety distance of himself and the vehicle in front, which makes it easy to fail to make correct judgments when the vehicle in front brakes suddenly or in an unexpected situation, or because the braking distance is too short and the vehicle speed is too fast There are also traffic accidents when overtaking, because the speed and distance of the oncoming vehicle are underestimated, and blind overtaking is carried out, or when overtaking, because the speed of the oncoming vehicle is too fast, there is no time to respond and a traffic accident occurs These accidents ...

Problems solved by technology

However, the driver sometimes underestimates or deviates from the speed and safety distance of himself and the vehicle in front, which makes it easy to fail to make correct judgments when the vehicle in front brakes suddenly or in an unexpected situation, or because the braking distance is too short and the vehicle speed is too fast There are also traffic accidents when overtaking, because the speed and distance of the oncoming vehicle are underestimated, and blind overtaking is carried out, or when overtaking, because the speed of the oncoming vehicle is too fast, there is no time to respond and a traffic accident occurs These accidents have brought heavy consequences to society, victims and their families. In view of this phenomenon, if a kind of intelligent vehicle distance judgment and overtaking auxiliary system can be proposed, the occurrence of this phenomenon can be effectively avoided.
