Abstract

An Electronic Control Unit (ECU) is an embedded system in automotive electronics that control one or more electro-mechanical systems or subsystems in a vehicle. For a sophisticated automotive will almost have 200 ECUs for multipurpose. Optimal Accelerated Life Test (ALT) Plan of Temperature Cycling (TC) and Mechanical Vibration (MV) for ECU are developed. TC is carried out as per IEC60068-2-14 (Nb) and MV was carried out as per IEC60068-2-64. Failure data is recorded and fitted to Weibull Distribution using Maximum Likelihood Estimation (MLE) in Minitab. Coffin and Manson Model (CMM) has been used to observe failures due to TC and Minor Fatigue Model (MFM) has been used to observe failures due to Random MV. Reliability and Life of the ECU are estimated and compared with Sherlock Simulation.
