Abstract

The invention relates to an automobile driving assisting system which comprises a host, an actuating mechanism and a sensing circuit, wherein the host comprises a central processing unit, an input interface circuit and an output interface circuit; the sensing circuit comprises a steering wheel angle sensing circuit, a short-range distance meter, a long-range distance meter and an automobile speed sensing circuit; the actuating mechanism comprises a brake control mechanism and an oil channel control mechanism; the central processing unit is connected with the input and output interface circuits through a data bus; and the steering wheel angle sensing circuit, longitudinal/transverse acceleration sensing circuits, the short-range distance meter, the long-range distance meter and the automobile speed sensing circuit are respectively connected with the input interface circuit. By organically combining acoustic, optical and electric sensing technologies with the computer technology, the system has the advantages of high intellectualization, high sensitivity, high reliability, all-weather use and the like. Under the premise of not changing the structure and the performance of the original automobile, the automobile provided with the system can become an intelligent automobile which not only has the active collision prevention and automatic alarm functions but also has the driving assisting function.

Description

technical field [0001] The invention relates to an automobile driving system, in particular to an automobile driving assistance system. Background technique [0002] With the continuous improvement of the quality of life of the general public and the acceleration of the pace of life, various cars have increasingly become the mainstream means of transportation for people of different classes to participate in social activities and logistics. Therefore, people rely on cars because it brings convenient and fast life, expands people's range of activities, and extends people's horizons. However, while automobiles bring convenience and speed to people's life, they are also accompanied by traffic accidents. Traffic accidents not only bring material losses, but also have a bad impact on people's life safety, and even life-threatening when serious. [0003] In order to reduce the incidence of car accidents, the car must measure the distance of the obstacle ahead with certain equipme...
