A Vehicle-Based Intelligent Drunk Driving Prevention and Control System

Abstract

The invention discloses an intelligent drunk driving prevention and control system based on a vehicle.The intelligent drunk driving prevention and control system comprises a perception layer, a decision making layer and an execution layer.The perception layer comprises alcohol detection sensors, a steering wheel angle sensor and a torque sensor.The decision making layer mainly comprises a control unit ECU.The execution layer comprises an engine management system (EMS), an indication lamp module, a voice prompting module, a GPS positioning module and a drunkenness assistance module.A skin contact type sensor and an expiration type sensor are adopted for the alcohol detection sensors of the perception layer, and the accuracy of the detection of alcohol concentration in the body of a driver can be improved by synthesizing test data of the two sensors; the steering wheel angle sensor and the torque sensor are shared by an electric power steering (EPS) system.The drunk driving prevention and control system is started through a touch control mode, the driver can be effectively prevented from 'cheating', and drunk driving can be accurately and effectively prevented.A keyboard is arranged on a terminal of the drunkenness assistance module.The drunk driving driver can selectively send a distress signal according to the actual situation of himself / herself.

Description

Technical field: [0001] The invention belongs to the field of automobile active safety, and specifically proposes a vehicle-based intelligent drunk driving prevention and control system, aiming at preventing drunk driving and reducing the accident rate caused by drunk driving. Background technique: [0002] With the rapid development of the economy and society and the significant increase in car ownership, cars have brought great convenience to people, but they have also increased the pressure on road traffic. Among them, frequent road traffic accidents have caused serious economic losses and a large number of casualties. According to statistics, a large part of traffic accidents are caused by drivers drinking and driving. Medical research has proved that the impact of alcohol on drivers is mainly reflected in the following aspects: alcohol will affect the driver's ability to correctly judge the distance; alcohol will affect the driver's attention, coordination and response...

Problems solved by technology

[0004] At present, although some control systems for preventing drunk driving have realized the function of preventing drunk driving, there are also some problems as follows: 1) the breath-type type alcohol sensor is used, which cannot well avoid the influence of other drinkers in the car on the detection device, thus The inaccuracy of the alcohol test will even affect the normal driving of the car; 2) It cannot effectively prevent the driver from "cheating", that is, let the non-drinking driver take the alcohol test instead of the drinking driver, thereby muddling through and burying a major driving safety problem. Hidden dangers; 3) After the driver is detected to be drinking, especially drunk, although the engine is prohibited from starting to make the vehicle unable to drive, since there are no follow-up service measures, even if the purpose of preventing drunk driving is achieved, it will also lead to user dissatisfaction. low acceptability
