Abstract

A vehicle-mounted safety control device for detecting fatigue driving comprises a first ECU, a second ECU and a third ECU. The first ECU, the second ECU and the third ECU are connected on a CAN bus of the same gateway. A video capture module, a storage module and a voice alarm module are respectively connected with the first ECU used for detecting the fatigue driving, a camera module is connected with the video capture module, a brake pedal sensor and a speed sensor are respectively connected with the second ECU used for ABS (anti-lock braking system), and an accelerator pedal position sensor and a piston position sensor are respectively connected with the third ECU used for automatic speed changing. The vehicle-mounted safety control device for detecting the fatigue driving has the advantages of being low in power consumption, high in reliability, good in stability, low in cost, and capable of reducing traffic accidents to some extent, reducing damages caused by the traffic accidents, and improving the safety of driving for drivers and walking for the public.

Description

A kind of vehicle-mounted fatigue is driven and is detected safety control
Technical field
The utility model relates to a kind of intelligent vehicle-carried fatigue driving detection and safety control.
Background technology
Fatigue driving is the one of the main reasons that causes traffic accident.According to statistics, the traffic accident that driving fatigue causes is that absolute number or proportion are all the highest.How effectively to detect the fatigue state of chaufeur, and in the time that it occurs sleepiness, warn or remind its rest of stopping to become study hotspot.Apply intelligent vehicle-carried fatigue driving detection and safety control system and initiatively prevent traffic accident, can reduce to a certain extent the generation of traffic accident, reduce the harm that traffic accident brings, make chaufeur driving and Public Traveling safer.
Summary of the invention
The purpose of this utility model is to provide a kind of intelligent vehicle-carried fatigue driving detection and safety control, it have low in energy consumption, reliability is high, good stability, low cost and other advantages.
The utility model is achieved like this, a kind of intelligent vehicle-carried fatigue driving detection and safety control system, it comprises an ECU, the 2nd ECU and the 3rd ECU, an ECU, the 2nd ECU and the 3rd ECU are connected in the CAN bus of same gateway; An ECU who detects for fatigue driving is connected with video acquisition module, memory module, audio alert module respectively, and camera module is connected with video acquisition module; The 2nd ECU for abs braking anti-lock connects respectively brake pedal sensor and car speed sensor; Connect respectively accelerator pedal position sensor and piston position sensor for self-shifting the 3rd ECU.Described an ECU, the 2nd ECU and the 3rd ECU are embedded ARM processor.Described video acquisition module is cmos image sensor.
Technique effect of the present utility model is: the utlity model has low in energy consumption, reliability is high, good stability, low cost and other advantages, can reduce the generation of traffic accident to a certain extent, reduce the harm that traffic accident brings, make chaufeur driving and Public Traveling safer.
Accompanying drawing explanation
Fig. 1 is block diagram of the present utility model.
The specific embodiment
Intelligent vehicle-carried fatigue driving detection and safety control system block diagram as shown in Figure 1, it comprises an ECU, the 2nd ECU and the 3rd ECU, an ECU, the 2nd ECU and the 3rd ECU are connected in the CAN bus of same gateway; An ECU who detects for fatigue driving is connected with video acquisition module, memory module, audio alert module respectively, and camera module is connected with video acquisition module; The 2nd ECU for abs braking anti-lock connects respectively brake pedal sensor and car speed sensor; Connect respectively accelerator pedal position sensor and piston position sensor for self-shifting the 3rd ECU.Described an ECU, the 2nd ECU and the 3rd ECU are embedded ARM processor.Described video acquisition module is cmos image sensor.Actual use is such, video acquisition module control camera module Real-time Collection chaufeur facial image information, then data are sent in the SDRAM of memory device with dma mode by PPI interface, the complete two field picture of every transmission, the one ECU(fatigue driving detecting system) by fatigue detecting Algorithm Analysis input data and the video flowing of operation, by detecting the fatigue of method reflection chaufeur of closed degree information of driver's eyes, it can reflect fatigue state exactly.Then video MPEG-4 compression coding is saved in the IDE hard disk of memory module.In the time driver fatigue being detected, can send voice warning by audio alert module.If warn continuously No. three the automobiles first ECU(fatigue driving detecting system that still do not slow down) just will brake or restriction signal (determining to brake or deceleration according to the degree of fatigue detecting) uploads to automobile CAN gateway by CAN bus, gateway is according to control policy, by CAN bus, braking or restriction signal are passed to the 3rd ECU(automatic speed-changing system again) and the automatic antiblock device of the 2nd ECU(ABS), make automobile in best gear and the braking of startup ABS antiblock device or deceleration, because automobile application CAN fieldbus is more extensive at present, therefore the convenience in order to be connected with the electronic control system of automobile, so increased CAN bus interface.
