A study on the case of sudden car accident estimation of frequency slope estimation method

초록

As automobiles become more common, accidents caused by sudden outbreaks are increasing every year. In this paper, we use a slope of the frequency change to analyze the vehicle. The values measured using these slopes are very important features for objective analysis. Therefore, in this paper, we propose a method to detect sudden emergencies by analyzing sound source of black box engine sound in order to identify suspicious accidents of vehicle type and to minimize damage caused by accident. Experimental results show that the fundamental frequency increased significantly from 90Hz to 180Hz for a short time unit (1 second) and showed the instantaneous slope graph. The slope of the sound source 1 and the sound source 2 corresponding to the medium-sized car was 50 to 100, and the slope of the sound source 3 corresponding to the semi-medium-sized car was 179.59. Therefore, this study can be continued to standardize the rapid acceleration limits of various vehicle types and to accurately identify the sudden acceleration. © Research India Publications.
