Warning and intervention system for drunk driving of drivers and operation and control method of warning and intervention system for drunk driving of drivers

Abstract

The invention discloses a warning and intervention system for drunk driving of drivers and an operation and control method of the drunk driving detecting, warning and intervening system. The system comprises a system enable detection unit, a driver alcohol detection unit, a driver response ability detection unit and an execution unit, the system enable detection unit consists of a WISDD (warning and intervention system for drunk driving) controller (20), a vehicle door opening sensor (11) and a driver seat pressure sensor (12), the driver alcohol detection unit comprises a primary alcohol detection unit and a secondary blowing type alcohol detection unit (6), the driver response ability detection unit comprises four signal lamps and four switches, structures of the four signal lamps are identical, structures of the four switches are identical, and the execution unit mainly consists of a voice prompting loudspeaker (3), a speed limiting prompting lamp (4), a double-flash warning relay (13), a double-flash warning lamp (15) and a system fault lamp (17). The system enable detection unit, the driver alcohol detection unit, the driver response ability detection unit and the execution unit are respectively connected with the WISDD controller (20) by electric wires. The invention further provides the operation and control method of the warning and intervention system for drunk driving of drivers.

Description

technical field [0001] The invention relates to a driver's drunk driving detection warning intervention system (WISDD: Warning and Intervention System for Drunk Driving). Specifically, the present invention relates to a vehicle-mounted device for detecting and judging a driver's drunk driving behavior ability, intervening in vehicle speed, storing illegal behavior, and warning pedestrians, and also provides a control method for the driver's drunk driving detection and warning intervention system. Background technique [0002] Drunken driving, especially drunken driving, is very serious to the harm of road traffic safety. Drunk driving has been listed as the leading cause of death in traffic accidents by the World Health Organization, and about 50% to 60% of traffic accidents are related to drunk driving. After a driver drinks excessively, the alcohol concentration in the blood has a direct impact on the driver's ability to operate. For drivers, when the blood alcohol conce...

This judgment method ignores the differences in the drivers' individual physique and alcohol capacity, and does not distinguish between drunkenness and drinking

And when the detection exceeds the predetermined value, the engine will not be ignited directly. Like this, if the driver encounters an emergency (such as hijacking, natural disasters, etc.) and is only slightly drunk but still possesses safe driving ability, unnecessary losses may be caused.

Furthermore, the non-mouth blowing device, because only one alcohol...
