Description: The complexity of software within passenger cars has increased considerably in recent years and is still growing. The number of components and the scope of intelligent hardware modules as well as the complexity and size of the software have multiplied. And this concerns not only the functionalities that have been needed in cars for many years. In addition, there are further control units that perform signal processing, and decision-making based on measured signals for a wide variety of new sensors. Annette Kempf, CEO of Eclipseina eclipseina.com, used to work as a software developer for combustion engine control systems and is giving insights in the embedded development of powertrain software. Like most of the engineers having worked in this field, she then switched to e-mobility, which askes for faster control algorithms, power electronics and electrical machines. While some of the know-how is required for both engine types, combustion engine and electrical motor, other parts changed completely. The common ground know-how includes typical microcontrollers, the ASPICE process framework, and the bus connections, like LIN, CAN, FlexRay, Ethernet, and SENT youtube.com/watch?v=VF1uUKLReFQ. The basic software drivers which are partly provided as MCAL layer software by the chip producers and the architecture principles defined by Autosar are also mostly in common for both engine types. And what is different for electrical machines? To design control algorithms you need to understand the electrical machine and the power electronics including IGBTs or MOSFETs used for high power switching. youtube.com/watch?v=h5PuZw-FR6A Also the charging of the vehicle is a more complex topic than probably expected in the first place. Different standards in China, Europe, Japan and the US are only a part of the problem as the standardization has changed over time and still has gaps which is resulting in communication problems. This means that not every electric vehicle EV is able to communicate with every charging stations EVSE. youtube.com/watch?v=Balv8tg3Xqg The Embedded Academy e-learnings embedded-academy.com/e-learning-portfolio-en help engineers to master the transition from embedded software development for diesel and gasoline projects to develop solutions for electric vehicles in the future by providing both basics and the dedicated know-how needed for the electrified powertrain and for electric charging.
