Automobile low-speed following driving assistance system and decision making method of automobile low-speed following driving assistance system

Abstract

The invention discloses an automobile low-speed following driving assistance system and a decision making method of the automobile low-speed following driving assistance system. The system comprises a distance sensor, a signal processing unit, a control unit and an automobile interface unit, wherein the distance sensor is used for detecting the spacing distance between a current automobile and a preceding automobile; the output end of the distance senor is connected with the signal processing unit; the output end of the signal processing unit is connected with the control unit; the output end of the control unit is connected with an automobile driving unit through the automobile interface unit; a speed sensor used for collecting automobile running speed information is arranged in the automobile driving unit; and the output end of the speed sensor is connected with the signal processing unit through the automobile interface unit. The system can be used for assisting an automobile driver to operate the automobile to advance or to brake in a traffic jam driving state; the driving fatigue degree of the driver can be reduced; the occurrence of traffic accidents is prevented; the distance with the preceding automobile can be monitored and controlled in real time; the occurrence of traffic accidents such as rear-end collision can be effectively avoided; the traffic efficiency of the automobile can also be improved; and the traffic jam is relieved.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to an automobile low-speed following driving assistance system and a decision-making method thereof. Background technique [0002] At present, automobile driving assistance technology is more and more applied to various automobile products. Its main function is to assist the driver to operate and control the driving of the automobile, so as to improve the safety and comfort of automobile driving. From the early electric windows to the popular lane keeping assist system, automatic parking assist system, brake assist system, reversing assist system, adaptive cruise control system, etc. These driving assistance systems greatly facilitate the operation and use of the car, and improve the safety and comfort of car driving. [0003] People who drive in the city often encounter traffic jams. In this case, usually the driving speed is relatively slow, and stop...

AI Technical Summary

Problems solved by technology

In this driving state, drivers are more prone to fatigue due to high concentration and frequent driving, which will bring discomfort to the body and easily lead to traffic accidents such as rear-end collisions and collisions, which will further aggravate traffic congestion. status

However, in the existing car driving assistance systems, there is no driving assistance system that can help the driver to operate and control the car in this driving state.
