Evaluation method and system for driving attention distraction caused by automobile HMI design

Abstract

The invention discloses an evaluation method for distracting driving attention caused by automobile HMI design. The method comprises the following steps that an HMI visual foothold detection model analyzes and obtains a driver attention area on an HMI picture according to the input size of an HMI display device, position data in a cockpit and input HMI picture data, and marks the driver attentionarea; the HMI operation attention distraction evaluation model outputs the number of fixation points, the number of review times, the fixation duration and lane departure and speed maintenance data ofthe HMI picture. The invention further provides an evaluation system for the driving attention distraction caused by the automobile HMI design. The evaluation system comprises an HMI visual footholddetection model, an HMI operation attention distraction evaluation model and an HMI operation driving safety influence grade classification model. By adopting the technical scheme, the collected datais accurately marked by combining the HMI picture, and the analysis target can be accurately marked to the design element by using the target detection method, so that a designer is guided to accurately improve the problem.

Description

technical field [0001] The invention relates to an evaluation method and system for driving distraction caused by automobile HMI design, and belongs to the technical field of automobile research and development and design. Background technique [0002] With the continuous application and promotion of intelligent network technology in the automotive industry, more and more models represented by Tesla are equipped with smart cars, and their functions are becoming more and more diversified, such as navigation, music playback, air conditioning control, etc. More and more applications such as video, video, games and audiobooks have begun to be carried on this platform. However, the driving scene is different from that of the PC or mobile phone, and its driving safety is particularly important.

Problems solved by technology

However, the driving scene is different from that of the PC or mobile phone, and its driving safety is particularly important. The distraction caused by the unreasonable design of the HMI (Human Machine Interface) is very dangerous for the driver, but not all responsible for the HMI Design and R&D OEMs, design companies, and automotive application content suppliers all have the ability to evaluate HMI design, and it is difficult to verify whether the HMI design meets safety standards. The current evaluation is mostly based on actual road scenarios. During the task, the safety of the testers is difficult to guarantee, and it will cost a lot of money. Therefore, the HMI design often skips the safety test evaluation link. In this case, the HMI design has a very large safety hazard

At present, OEMs and various application developers with HMI design capabilities have the following problems: 1. It is difficult to quantitatively evaluate the safety design rules that are subjectively inferred and formulated by designers; 2. Only developed products can be tested for actual road conditions. The cost of testing, risk, and trial and error is very high, and it is difficult to actually implement it
