Vehicle alcohol detection control system and test method

Abstract

The invention relates to the field of car electron, in particular to an alcohol detection control system and a used test method. The test method of the vehicle alcohol detection control system comprises the following steps: a driver judges whether starts to drive according to a lock switch of a car door and a push switch arranged on the seat of the driver, and a standby state of the system is switched to the working state; a signal is sent to an alcohol sensor by a microprocessor, and the alcohol sensor automatically tests; when the alcohol concentration tested by the alcohol sensor does not exceed 0.0454 mg / L, a solid-state relay is closed, and the vehicle is allowed to start; the test program is started up; the reaction ability and the coordination ability of hands and eyes of the driver are judged in a test program after the test program is started up; if the driver passes through the test, a highest allowance vehicle speed is set, the solid-state relay is closed, and the vehicle is allowed to start at limited speed; and if the driver does not pass through the test, the solid-state relay is cut off, the vehicle is forbidden to start. With the adoption of the vehicle alcohol detection control system and the test method, vehicles can be accurately and flexibly controlled, thereby drunk driving is effectively controlled.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to an alcohol detection control system and a testing method used therein. Background technique [0002] Drunk driving has always been a heavy topic, and the disastrous car accidents caused by drunk driving have made people hate drunk driving. People take multiple measures to curb the phenomenon of drunk driving, but some people are forced to drink under various environmental influences, and then they drink and drive with luck, ignoring the harm of drunk driving. The traffic police department uses the alcohol tester to go on the road to check whether the driver of the vehicle is drinking, and uses its authority to supervise the detection. The alcohol tester can obtain accurate breath alcohol concentration. But it is mainly used by the traffic police to enforce the law and occurs after the driver is driving, and cannot fundamentally stop drunk driving. In addition, some people ...

[0003] But using only gas alcohol content to control vehicle ignition has a big disadvantage

Due to individual differences, different people have different levels of tolerance to alcohol, and the blood alcohol content cannot fully reflect the impact of alcohol on a person's driving skills; secondly, in the closed unsupervised space of the car, determine the source of the gas and accurately measure it The concentration of exhaled alcohol gas is relatively difficult. No matter how close the alcohol sensor is to the driver, what the sensor detects is still a mixture of the driver’s exhaled gas and the gas in the car, and the alcohol concentration of the exhaled gas cannot be accurately measured; in addition, it cannot be judged whether the driver Drinking alcohol may cause the vehicle to fail to start due to the co-pilot or other sources of alcohol; furthermore, it is impossible to determine whether the driver cooperates with the detection
