A Measuring Device and Monitoring Method of Driver's Pedal Operation Behavior

Abstract

The invention relates to a monitoring technology of an operation behavior of an automobile driver and discloses a measuring apparatus for an operation behavior on a pedal by a driver and a monitoring method thereof. The measuring apparatus comprises: a camera, wherein the camera is fixed on a base plate of a cab and a lens of the camera is headed to an accelerator pedal, a brake pedal, and a clutch pedal and is used for simultaneously collecting motion images of the three above-mentioned pedals; a video collection card, which is electrically connected with the camera and is used for transmitting the motion images of the three above-mentioned pedals; a computer, which is electrically connected with the video collection card and is used for receiving the motion images from the video collection card and comparing and determining actual positions of the three pedals according to foot image positions of a driver at different times to obtain a name of the pedal that is operated by the driver and operation time of the pedal, wherein the foot image positions are obtained by image processing; In addition, the monitoring method comprises the following steps: pedal position calibration; calibration on a column gray scale threshold of a pedal, image collection, image preprocessing, and determination and record on a driving behavior.

Description

technical field [0001] The invention relates to a technology for monitoring the operation behavior of a driver, in particular to a measuring device for the driver's pedal operation behavior and a monitoring method thereof. technical background [0002] The driver's operation behavior on the vehicle pedal directly affects the safe operation of the vehicle and is an important part of driving behavior. Vehicle pedals include accelerator pedal, brake pedal and clutch pedal. When conducting experimental research on driving behavior and vehicle performance, it is usually necessary to measure and record the driver’s operation behavior on the pedals. Specifically, it is necessary to measure which pedals the driver operates at any time, the duration of the operation of a certain pedal, and the duration of the operation. The speed of switching between different pedal operations, etc., to reflect the driver's driving behavior during driving. The driver’s operation on the pedal is div...

AI Technical Summary

Problems solved by technology

These two methods have certain shortcomings. The installed force sensor and displacement sensor will cause some interference to the normal operation of the driver, resulting in differences between the driver's pedal operation behavior and the normal pedal operation behavior, which affects the experimental results. accuracy of results

On the other hand, using a force sensor or a displacement sensor can only determine the pedal operation when the driver steps on the pedal, but cannot determine that the driver has placed his foot on a certain pedal and has not stepped on it. If the driver puts his foot on the brake pedal, but has not stepped on the brake pedal to brake, the driver is ready to brake

Using force sensors and displacement sensors, it is impossible to judge that the driver puts his feet on the pedals, but does not step on the pedals.
