BMW’s next-generation electric vehicles (EVs) are set to revolutionize the driving experience, thanks in part to an unassuming black box known as the “Heart of Joy.” This all-in-one Electronic Control Unit (ECU) was designed by BMW engineers in-house and has been developed to power a variety of driving dynamics across the brand’s lineup.
The Heart of Joy combines driving dynamics and powertrain control into one computer, serving as the control module for upcoming Neue Klasse electrified vehicles. With its unique development process, which took just three years and over 7,500 hours of testing, BMW aims to differentiate its EVs from competitors like Kia.
One of the major features of the Heart of Joy is braking and stability control, which can actively use regenerative braking to bring vehicles to a full stop without driver input. This results in more stability at the limit and recuperation that’s 60 percent more efficient. The system also enables less latency in vehicle response, reducing wear and tear on brakes and tires.
BMW’s Chief Technical Officer (CTO) Frank Weber attributes the company’s success with this project to its near-miss experience launching the 7-series 25 years ago. This failure forced BMW to develop more robust processes for advanced digital technologies earlier than others. With the Heart of Joy, BMW aims to minimize risks associated with globalization in the automotive industry.
The new ECU system brings BMW closer to its “Ultimate Driving Machine” roots and promises a dynamic all-electric driving future. With its cutting-edge technology and commitment to regionalization, BMW is poised to revolutionize the EV landscape.
