The powertrain domain controller is an intelligent powertrain management unit that leverages CAN/FLEXRAY for transmission management, engine management, battery monitoring and alternator regulation. Its advantages include computing and distributing torque for a variety of powertrain units (internal combustion engines, electric motors, generators, batteries and transmissions), reducing CO2 emissions through predictive driving strategies, and acting as a communication gateway. It is mainly used for powertrain optimization and control, while also providing intelligent electrical fault diagnostics, smart power saving and bus communication functions.
