Overcome the challenges of electric vehicle embedded software development

Reading time: 29 minutes

With the shift toward electrification in the transportation industry comes a heavy burden for engineers and software architects to design safe, secure, and hassle-free systems. All six components of an electric vehicle (EV) powertrain system must function in perfect harmony for maximum performance. Still, there are several architectural challenges and security and safety considerations. Additionally, charging protocols vary depending on geographical region and are constantly evolving. Because of the sheer complexity of electric vehicle (EV) embedded software for electrical powertrain systems, automotive software developers require purpose-built solutions to tackle the complex issues faced during development.

Architectural, safety, and security challenges of embedded software for EVs

Arguably the number one requirement for any vehicle is that it is safe on the road at all times, and with the introduction of high-voltage components, safety requirements for EVs are even more stringent. As modern vehicles become increasingly connected using a highly sophisticated electrical architecture with many entry points, EVs are also vulnerable to cyber threats such as ransomware, malware, or DDoS attacks, putting personal data and payment information at risk. Additionally, ECU developers must grapple with new architectural challenges. While EVs and plug-in hybrid EVs are well established in the market, chargers and charging technology are still evolving, so ECUs need to be developed using a communication stack, keeping the EV compatible with the EVSEs available at the roadside.

Reduce hardware dependency with integrated E/E systems development

Further adding to the complexity of EV systems, all EV components must be designed to meet the designated Automotive Safety Integrity Level (ASIL) requirements for overall system safety. To that end, a microcontroller and an AUTOSAR stack with multicore support and AUTOSAR BSW are extremely helpful. AUTOSAR is the dominant standard for automotive software; all major automotive OEMs and most tier-one suppliers are involved in developing the AUTOSAR standard. Production-proven, Siemens complete solution enables an AUTOSAR-aware environment for integrating, testing, and analyzing software while reducing hardware dependency.

How a multicore solution addresses the challenges of EV embedded software design

Today, advanced, integrated E/E systems development tools are required to deliver tomorrow’s advanced automotive products. Capital VSTAR’s multicore solution enables software distribution that is particularly useful for addressing the performance and safety challenges of EV embedded software design. It also provides a solution to the security challenges of developing a software platform to power high-performing ECUs that drive today’s electric vehicles.
