In the framework of tighter emission requirements and environmental protection, future standards will soon lead to the use of an on board diagnostics (OBD) soot sensor to monitor Diesel particle filter (DPF) leakage. The sensor will first be introduced in the US by MY 2015 and then in Europe in 2017. The resistive ceramic sensing technology has been selected by most OEM as the most appropriate. The smart soot sensor must diagnose filter leakage whatever the driving conditions are, smoother or tighter than the standard NEDC, FTP or WLTC cycles. In order to guarantee a robust detection of failure, Electricfil Automotive and IFPEN have developed strategies capable to accommodate with OEM request and available database. The paper describes the innovative hardware and software solutions and presents the simulated and measured performances.
