Embodiment Construction

[0030] The driver's cognitive load test device based on detection and response tasks of the present invention, such as figure 1As shown, its main components include vibration module 1, vibration module-chip connection insulation wire 2, Arduino Uno R3 chip 3, computer terminal with control program 4, chip-computer connection wire 5, button 6, button-chip connection insulation wire 7.

[0031] The connection relationship of the above components is as follows:

[0032] The vibration module 1 is connected to the Arduino Uno R3 chip 3 through the vibration module-chip connecting insulated wire 2 . Button 6 is the response component of the cognitive test attention device, which is bound with the index finger pulp of the driver's dominant hand through Velcro. Every time a vibration stimulus is detected, the driver presses button 6 with the thumb of the dominant hand to complete the detection and response task. The button 6 is connected to the Arduino Uno R3 chip 3 through the butt...

Abstract

The invention belongs to the technical field of automobile driving assistance systems and discloses a touch detection response task based driver cognitive load testing device, which mainly comprises avibration module, an Arduino Uno R3 chip, a button and a computer terminal with a control program. The vibration module is fixed to a driver's body by adhesive tapes, the button is bound to a forefinger of a dominant hand of a driver, and the vibration module and the button are connected with the Arduino Uno R3 chip through an insulating line. The chip is internally provided with a hardware control program and communicated with a software control program of the computer terminal through a serial port to realize detection response task triggering, performance data recording and data file generation. By application of the touch detection response task based driver cognitive load testing device, cognitive load allowance testing of products such as an increasing number of automobile electronic devices under a driving state can be completed conveniently and quickly, difference in crowds can be tested simply, conveniently and quickly, portability and simplicity in use are realized, and insusceptibility to normal head motion of the driver in a driving process is realized.

Description

Technical field: [0001] The invention belongs to the technical field of automobile driving assistance systems, in particular to a driver's cognitive load testing device. Background technique: [0002] Along with the overall development of our country, the number of traffic accidents in our country is also increasing rapidly. In the occurrence of traffic accidents, the driver's use of mobile phones, broadcasting and other human-computer interaction devices, which distracts the driver, should not be underestimated. Cognitive distraction of drivers while driving has a considerable impact on driving safety. The total amount of driver's attention is limited. When the driver shifts part of his attention to behaviors that are not related to driving safety, the driver's attention on driving will inevitably decrease, making the driver less sensitive to driving emergencies. The reaction time increases, which increases the safety risk of driving. In recent years, with the developmen...
