Abstract

The invention discloses a driver attention testing device based on a detection response task, and belongs to the technical field of an automobile driving assistance system. The device is mainly composed of an adjustable helmet which is provided with an LED lamp soft hose, an Arduino Uno R3 chip, a button and a computer end carrying a control program, wherein the adjustable helmet provided with the LED lamp soft hose is worn on the head of a driver; the soft hose extends from the left side face of the driver and the button is bound with the pulp of the index finger of a dominant hand of the driver, and the soft hose and the button are connected to the Arduino Uno R3 chip by virtue of insulating wires; and a hardware control program, which is arranged in the chip, of the driver attention testing device can communicate with the software control program of the computer end by virtue of a serial port, so as to achieve detection response task triggering, performance data recording and data file generating. The driver attention testing device disclosed by the invention, with the application, can conveniently conduct distraction degree testing on such increasing products as automobile electronic equipment and the like under a driving state, and the driver attention testing device can conveniently and rapidly test differences in people; and the driver attention testing device is convenient to carry and simple to use, and the driver attention testing device is not affected by normal head motions of the driver during driving.

Description

Technical field: [0001] The invention belongs to the technical field of automobile driving assistance systems, in particular to a driver's attention testing device. Background technique: [0002] In the road traffic system composed of personnel, motor vehicles and road environment, motor vehicle drivers are a weak link in the system. The driving process is complex, including multiple links such as situation awareness, decision-making, and execution. It is inevitable that sudden abnormalities such as distraction errors and judgment errors will directly lead to increased driving risks. Driving is a highly complex information processing (cognitive) process, which can be divided into three stages: situation awareness, decision-making and execution. The driver's attention resources are used to process a large amount of information, make complex decisions, and sometimes process multiple Task. Attention is regarded as an important mechanism of information processing by cognitive ...
