This paper presents a surrogate modeling technology and the application using the response surface methodology (RSM) for a half-wave rectified brushless synchronous motor (HRSM) for model-based design. HRSM adopts a field winding that is single-phase short-circuited through a diode, instead of a brush at the rotor. This brushless excitation facilitates the maintenance of the motor and variable field flux operation. However, creating a high accuracy motor model for model-based design using HRSM considering field current characteristics with the effects of the diode is difficult, and the problem of an unrealistic complex calculation for applications such as drive cycle simulations exists. To overcome these challenges, we propose a surrogate modeling technique for HRSM using RSM and finite element analysis. The objective of this study is achieve the fast and accurate simulation to predict the wide range and long-time driving conditions of HRSM, which is difficult to validate experimentally.

In this study, we focused on detecting seat belts of drivers from camera images of the front windshield area of cars. When the color of the seat belt differs from that of the clothing worn by the driver, the seat belt can be detected by focusing on edge and pixel value differences. This study created a template representing pixel value differences and applied template matching using a genetic algorithm to achieve higher detection rates than edge-based methods. To quantitatively evaluate the performance, we created a dataset consisting of 73 images and compared the performances of each method. Notably, the proposed method achieved higher detection rates than the other methods.
