Multiple Sensing Method Using Moving Average Filter for Automotive Ultrasonic Sensor

Abstract

Distance sensing on vehicles is a trend in the development of autonomous cars. So that the use of proximity sensors such as ultrasonic and infrared, is very important. This research paper focuses on developing a reading of 4 ultrasonic sensors simultaneously. Where the reading method is done using 4 pin echo and 4 pins trigger and 1 pin echo with 4 pin triggers. In order for better reading, the programming algorithm for each method is integrated with the moving average filter. The use of this filter is able to correct the noise that occurs when reading the distance. The test was carried out at the computer simulation stage using a microcontroller. The final results of the study obtained a very small reading error.

Processing at the Edge: A Case Study with an Ultrasound Sensor-Based Embedded Smart Device

“…The resolution of the distance is 0.01 m, so it allows relevant variations of vehicle distance so that the detection algorithm can work efficiently. The relative error detected in the measurements is 0.74% on average [20] with a linear relation between distance and error [21]. The sensor sampling rate used in the device was 500 KHz in the experiments.…”

Penerapan Digital Moving Average Filter pada Sensor Dissolved Oksigen untuk Mengukur Kualitas Air

“…Produk DfRobot dengan kode SEN0237-A ini merupakan kit sensor oksigen terlarut, yang kompatibel dengan mikrokontroler Arduino [14]. Prasetyono, dkk [16], menyajikan tentang penerapan metode filtering moving average pada sensor ultrasonic yang dipasang pada mesin kendaraan. Karena getaran dari mesin menyebabkan penyimpangan pembacaan data yang cukup besar, maka digunakan filtering moving average untuk meredam noise pembacaan sensor.…”
