A driver behavior state data acquisition device and detection method

Abstract

The invention discloses a driver's behavior state data acquisition device and detection method. The data acquisition device includes a platform base, a seat, a power supply, an industrial computer, a display, an eye tracker, a grip sensing glove, a pedal assembly and a steering wheel. Assembly, in which the seat, power supply, display, industrial computer, pedal assembly and steering assembly are fixed on the base of the platform, the steering assembly is assembled on the upper part of the pedal assembly, and the display is located at the rear of the steering assembly and Corresponding to the seat setting, the method is as follows: the first step is to build two driving scenes; the second step is to collect three-axis acceleration and angular velocity information; the third step is to obtain the driver's eyeball focus direction; The direction is projected to the display plane; the fifth step is to classify the driver's hand posture; the sixth step is to identify the driver's visual distraction and cognitive distraction state. Beneficial effect: the deficiency of the current driver data collection device is solved, and the steering wheel is not required to be reformed.

Description

technical field [0001] The invention relates to a data collection device and a detection method, in particular to a driver behavior state data collection device and a detection method. Background technique [0002] At present, with the development of automotive intelligent technology, autonomous driving technology has become the mainstream research direction, but the current intelligent automotive technology is still difficult to support the large-scale implementation of autonomous driving vehicles, and human-machine co-driving and hybrid enhanced intelligent technologies are gradually attracting attention. Before the realization of fully automatic driving, the driver is still the main body of the car driving process, and will make corresponding active or passive actions according to the driving purpose or road conditions. The driver may experience distracted driving for various reasons, which affects the Driving safety can be roughly divided into visual distraction and cogn...
