The Challenges of Software in the Automotive Industry: Volvo’s Approach
Introduction
Building cars is a complex task that involves thousands of components working together to meet safety regulations and customer expectations. With the advent of electric cars, the automotive industry faces even greater complexity due to the integration of software for advanced safety and automated driving functions. Volvo, a leading car manufacturer, is leveraging this opportunity to revolutionize the in-car experience.
Software Engineering for Safety
Alwin Bakkenes, head of software engineering for Volvo, emphasizes that Volvo’s focus on software is driven by their commitment to safety. The advanced software capabilities in Volvo cars aim to make their products as safe as possible. Volvo utilizes software-defined vehicles (SDVs) to enhance safety through over-the-air updates. Unlike other car makers who only update maps, Volvo updates the software on ADAS control units and every ECU in the car if necessary.
The Benefits of the SPA2 Platform
Volvo’s new EX90 is based on the SPA2 platform, which offers improved computing power and software capabilities. Bakkenes highlights the platform’s ability to quickly add and enhance safety features. With the infrastructure in place, Volvo can continuously update and improve the performance of their vehicles by retraining models based on sensor data.
Software Beyond Code
According to Bakkenes, the term “software” encompasses more than just lines of code. It includes the software used to build the machine, test automation, integration machines, network infrastructure, and mobile applications. Volvo’s extensive cloud infrastructure and global network operators are also part of their software ecosystem.
The Challenges of Software Architecture
Building a software architecture for cars presents unique challenges for legacy car manufacturers. Bakkenes acknowledges that the transformation to becoming proficient in software was a tough journey. Volvo carefully selects which aspects to develop in-house and which to collaborate with suppliers on. While centralizing ECUs for easier updates is a common goal, Bakkenes believes that stability and efficient management of product variants are more important than minimizing the number of ECUs.
Learning from Feedback
Volvo’s previous model, the EX30, faced criticism for its software. Bakkenes acknowledges the importance of customer feedback and the need to deliver a fantastic experience. Over-the-air updates allow Volvo to address issues and continuously improve their products. Bakkenes encourages customers to share their observations and preferences, as Volvo values customer input and strives to meet their expectations.
Conclusion
Volvo’s focus on software engineering and advanced capabilities reflects their commitment to safety and customer satisfaction. By leveraging software-defined vehicles and the SPA2 platform, Volvo aims to continuously enhance the safety and performance of their vehicles. Through active listening and continuous improvement, Volvo strives to deliver exceptional in-car experiences to their customers.
