Efficient management of the power and energy flows taking place in a hybrid vehicle is the key to optimizing driving dynamics, reducing consumption and emission as well as ensuring safety. Applying our expertise in the entire vehicle and our know-how in developing production-ready control systems for all present-day drives, we also develop, simulate and test all energy-specific control functions in vehicles propelled by hybrid and electric drives.
We design the architecture for the energy-management system and develop the basic software and functions. This not only includes drive-related functions – first and foremost the systems for controlling the combustion engine, e-machine, power battery and hybrid manager – but also integrating the vehicle-related functions into the energy-management system, such as for controlling the energy from the power battery or generator for air-conditioning the passenger compartment.
Using our high-performance simulation tools, we can find the best possible solution for our clients’ particular needs in an early phase of the development process. We work with multi-criteria optimization in particular for resolving the trade-offs between drivability on the one hand and consumption and emissions on the other. In developing the safety concept and OBD functions of the energy management system, we follow the safety standards defined in IEC 61508 or ISO 26262.
Energy management functionality is validated and verified on our own hybrid powertrain test bench with battery simulator. And our experienced calibration engineers are there for calibrating the energy management system.
