Mechatronic or Electronic Modules are in mass production since 1998, with increasing market share. They are dominant at European and some North American transmission makers. In Japan and Korea most of the transmissions are controlled by PCU or sTCU with single components within the transmission or at least sensor modules in Korea. But with Jatco and Mazda two Japanese transmission makers have at least one product each with an electronic module in series. Main reason for Japanese transmission makers is to be flexible for upcoming variants of transmissions. But the complexity of variants among different car makers and different car classes can be handled as well with EM's as this is proven by the European companies. With increasing number of sensors and introduction of electric oil pumps the systems with sTCU and PCU require significant larger wiring harnesses outside and inside the transmission than in the past plus more complex connectors. Because of cost, weight and package reasons therefore the EM could become more interesting as well for confirmed sTCU customers. PCU system are declining as the complex combination of engine and transmission and the increasing complexity of the transmission control (content and calibration) itself sets limits to those systems. With the two product lines EM-2 and EM-3 Bosch is well prepared for all kind of modules, the worldwide operating customers and for all kind of automated transmissions.
