Abstract

This paper introduces and analyzes SAE J2716 SENT (Single Edge Nibble Transmission) protocol, a technical standard for serial transmission of digital sensor data in automotive applications. SENT can transmit both high-speed sensor data and low-speed sensor data in one data frame and has a total of 6 transmission modes, including 3 high-speed channel modes and 3 low-speed channel modes. In this paper, a SENT controller that supports all six modes of the SENT protocol was designed in Verilog HDL, implemented in FPGA, and verified with an oscilloscope and PC.

본 논문에서는 차량 어플리케이션에서 디지털 센서 데이터를 직렬 전송하는 기술 표준인 SAE J2716 SENT(Single Edge Nibble Transmission) 프로토콜을 소개하고 분석하였다. SENT는 하나의 데이터 프레임으로 고속 센서 데이터와 저속 센서 데이터를 함께 전송할 수 있으며 고속 채널 3개 모드, 저속 채널 3개 모드, 총 6개의 전송 모드를 가지고 있다. 본 논문에서는 SENT 프로토콜의 6개 모드를 모두 지원하는 SENT 컨트롤러를 Verilog HDL로 설계하고 FPGA로 구현하였으며 오실로스코프와 PC로 동작을 검증하였다.
