Driver status estimation system based on vehicle mounted sensor network

Specific embodiment:

Below and in conjuction with the embodiment of a detailed description of this invention, in order to have more of the present invention to further understand and recognized.

As shown in Figure 1, the vehicle sensor network-based driver state evaluating system, comprising:

1, vehicle running state evaluating sensor network, the real-time monitoring the speed of the vehicle, acceleration, position, steering wheel position, oil quantity, water temperature, power, voltage, current, air bag status, tire pressure, safe driving elements the temperature of the bearing, and the like, the reaction to the driver of the vehicle in the running state and the state of health. At the same time, vehicle running state sensor network offers the data to the vehicle driving state evaluating sensor network, the operating state of the driver of the vehicle with the vehicle running state is compared with the output state of the sensor network, the operating performance of the vehicle checks whether there is a danger, and the timely supplied to the current state of the driver, and vehicle operation management, improving vehicle safety inspection efficiency and reliability of the pump, reduce the regular safety inspection cost. Vehicle running state sensor node can be a concrete realization of the various detection technology, including a temperature detection circuit, a current detection circuit, the voltage detection circuit, the liquid level detection circuit, the code disc, vehicle speed sensor circuit, pressure sensor circuit, magnetic switch circuit means.

2, vehicle driving state evaluating sensor network, the real-time monitoring with the driver's driving behavior of the vehicle, including start-up, shifting, braking, parking, opening, closing, steering and driving behaviour switch signal lamp and the like, according to the vehicle driving state of the output data of the sensor node, one can initially determine whether the vehicle is in parking violation, peccancy traffic, traffic rules and regulations such as law, illegal acts, and the driver can be judged to be made when in emergency driving condition whether the driving behaviour of properly, to the traffic accident processing sector providing accident processing valid evidence. Vehicle driving state sensor node can be a concrete realization of the various detection technology, the magnetic switch circuit, the code disc, a digital input circuit, detection circuit of the electric current, a voltage detection circuit or the like detects the technical means.

3, real-time assessment of the driver's body of the sensor network quality, real-time monitoring of the physical state of the driver, including eye state, auditory state, physical index, reaction timeliness, sleep demand, psychological state, attention concentration influencing the driving of the main physical index. Quality real-time assessment of the driver's body according to the above-mentioned data of the sensor network to judge whether the driver of the current physical state of the ability to continue to drive the vehicle, replacing or remind the drivers rest in place. The quality of the driver's body of the sensor network real-time assessment of the recording data can also be used as a traffic accident processing sector accident processing reference. The quality of the driver's body of the sensor network real-time assessment of the machine vision means can be adopted to the fatigue of the driver when the mouth, eye movement of the real-time monitoring of the state of technology, ECG detection technology, humours electrolytic level detection technology, brain electrical technology, technology for detecting fatigue eye face the optic nerve, blood pressure, blood-sugar content, blood viscosity and other physical state detection technology and medical index measuring technology to the comprehensive assessment of the real-time index to the fatigue of the driver driving skill, the quality assessment of whether the current of the driver body is suitable to continue to assume the task of the driver.

Assessment system according to the vehicle running state evaluating sensor network to the vehicle running state is recorded and dynamic assessment, guarantee the security state of the vehicle; vehicle driving state evaluating sensor network to manipulation of the vehicle of the driver can carry out the recording and dynamic assessment, real-time observation of the level of control of the driver and service level, security driving safety; according to the driver's physical quality real-time assessment of the sensor network to assess the state of the driver's body, a capacity of a driving time period of driving the vehicle, reducing the probabilities of occurrence of fatigue driving, vehicle safety is ensured, road safety and traffic safe operation of the system.

Vehicle running state evaluating sensor network, vehicle driving state evaluating sensor network and the driver's body the sensor network, the quality of a real-time assessment of the on-board sensor network-based system for evaluating the state of the driver, and the driver of a vehicle during running before the driving action and physical quality to perform the real-time dynamic assessment, monitoring of the improving driving safety, reduce the occurrence of traffic accidents, guarantee safety and smoothness of the road. Assessment data can be provided by the system as the driver driving skills and driving ethics reference evaluation index. At the same time, data also can be a traffic accident to the traffic processing sector of the reference information that the liability for the accident.
