System and method for preventing fatigue driving of motor vehicles

Abstract

The invention provides a system for preventing fatigue driving of motor vehicles. A camera is installed at a pillow part of a driver seat, and is started to shoot a sitting posture image of a driver;a first pressure sensor and a second pressure sensor are arranged in a preset area of the bottom of the driver seat, and pressure values after the driver is seated are collected; an ECU receives the sitting posture image and pressure values collected by the first pressure sensor and the second pressure sensor, it is judged that a sitting posture of a driver fails when the sitting posture image ismismatched with a preset correct sitting-posture image or a pressure difference formed between the first pressure sensor and the second pressure sensor is larger than or equal to a preset threshold value, then an alarm command is issued to a sitting posture reminding module, and the sitting posture reminding module is driven to extract alarming information for voice broadcasting to remind the driver to adjust the sitting posture. According to the system and method for preventing fatigue driving of the motor vehicles, a fatigue driving state of the driver is identified combined with the image identification technology and the pressure sensing technology, the driver can be reminded in time to prevent fatigue driving, fatigue of the driver can be further relieved, and the driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of safe driving of motor vehicles, in particular to a system and method for preventing fatigue driving of motor vehicles. Background technique [0002] As one of the most important means of transportation for human beings, motor vehicle driving safety has been widely concerned by car companies and consumers. In recent years, the performance of motor vehicles has been significantly improved in all aspects, but the problem of driver fatigue driving has not been improved, and no corresponding measures have been provided for fatigue driving. [0003] As we all know, sitting for a long time, sitting with uneven force for a long time or incorrect sitting posture can easily cause problems such as thigh numbness, buttocks, lumbar disc herniation, and lumbar muscle strain. These phenomena often occur when driving for a long time. on the driver. [0004] Image recognition technology has been applied to the fields of...
