摘要：Abstract This paper aims to answer a key question during the design and development of a new product i.e. how many and where should one install the sensors to ensure effective health monitoring. In this paper, a sensor installation guideline for a 4R automatic transmission is presented. The guideline helps to visualize different possible combinations of sensors and their locations such that all malfunctions are monitored. The guideline is an outcome of structural analysis conducted on a kinematic model of the transmission. Faults in sensors, clutches and band brakes have been considered. The list of sensors include speed sensors to monitor shaft speeds and pressure sensors that can sense if the clutches/brakes are engaged or disengaged. It is concluded that turbine speed sensor, output shaft speed sensor and a pressure sensor can help to isolate all possible faults in the transmission under consideration.
