Introduction to Advanced Body Electronics: byteflight: Introduction

WARNING: This page does not describe the selected car, but rather 59 other vehicles, including the 2009 BMW M5, 2009 BMW 650i, 2009 BMW 550i, 2008 BMW M5, and 2008 BMW 760Li. However, it is still accessible from the selected car via links, so may be relevant.

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.
