Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Introduction to Advanced Body Electronics: byteflight: Introduction
The permanently increasing complexity of in-car electronics and the rapidly growing amount of sensors, actuators and electronic control units, places higher demands on high-speed data communication protocols.
Safety critical systems need quick "thinking" protocols with fault tolerant behavior. The need for onboard diagnostics calls for flexible use of bandwidth and an ever-increasing number of functions.
None of the communication solutions available on the market until now have been able to fulfill all these demands.
To solve these problems, BMW together with several semiconductor companies have developed byteflight a new protocol for safety-critical applications in automotive vehicles.
The byteflight is the bus system used exclusively for the ISIS system.
