Automotive Technology Overview Systems and products Safety Emissions Fuel consumption Driving pleasure Subjects Technical Solutions for commercial vehicles The car of tomorrow Trade Fair dates Business Divisions In China At a glance		Electronic Control Units Printed-circuit board technology is the tried-and-tested technol- ogy for ECUs for installation in locations with lower exposure to mechanical or thermal load, i.e. in the passenger compartment. ECUs in microhybrid technology feature an array of advan- tages compared to PCB design: even greater functionality compressed into smaller areas, lower weight and suitability for direct local installation with high mechanical and thermal loads. Bosch microhybrid ECUs have proven their reliability in millions of cars. ECU networking  Example for networking with CAN  More and more electronic components are being used to implement functions for safe, clean, and economic driving. In order to coordinate their performance, it is necessary for the ECUs to communicate with each other. This leads to the setting up of a functional alliance. Today, the Controller Area Network (CAN) developed by Bosch is the global standard for electronics networking in the vehicle. The advantages Wiring harnesses are superseded by a bus line Lower weight Simpler installation Lower costs	Product family Engine-management ECUs ECUs for active driving-safety systems ECUs for steering systems ECU modular systems The evolution of the Motronic ECUs  The first Motronic generation needed a lot of space. It was necessary to protect it, keep it cool, and vibration had to be kept to a minimum. Today's microhybrid ECUs on the other hand can be directly attached to the engine.
