Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, so as to have a further understanding and recognition of the present invention.

[0014] As shown in Figure 1, the driver state assessment system based on the vehicle sensor network includes:

[0015] 1. Vehicle driving status evaluation sensor network, which monitors the vehicle's speed, acceleration, gear position, steering wheel position, oil volume, water temperature, electricity, voltage, current, airbag status, tire pressure, bearing temperature and other safe driving elements in real time, and timely reports to The driver responds to the running status and health status of the vehicle. At the same time, the vehicle driving state sensor network provides data to the vehicle driving state evaluation sensor network, compares the vehicle driver's operating state with the output state of the vehicle driving state sensor network, checks whether there ar...

Abstract

The invention provides a driver state evaluation system based on an onboard sensor network which comprises a vehicle running state evaluation sensor network, a vehicle driving state evaluation sensor network and a driver physical quality real-time evaluation sensor network. The invention enhances monitoring strength of safety driving, reduces occurrences of traffic accidents and ensures safety and smoothness of road by evaluating driving behavior and physical quality of a driver before driving and during driving.

Description

technical field [0001] The invention relates to the field of sensor networks and intelligent transportation, in particular to a driver state evaluation system based on vehicle sensor networks. Background technique [0002] Information from the China Public Security Traffic Management Bureau shows that from January to September 2007, there were 241,734 road traffic accidents across the country, resulting in 57,168 deaths, 288,490 injuries, and direct property losses of 850 million yuan. In frequent traffic accidents, driver fatigue has become one of the main factors causing traffic accidents. [0003] Driver fatigue monitoring technology plays an important role in reducing traffic accident rate. At present, there are video processing, image processing, and a variety of technologies that can monitor the driver's fatigue. Vehicle driving status assessment and vehicle driving status assessment technology have also made great progress. Most high-end vehicles are equipped with d...
