Abstract
Relaxed cruising with Active Cruise Control, without having to adjust the riding speed to the vehicle in front – already available in cars for years, not yet in series production for motorcycles. BMW Motorrad is the first motorcycle manufacturer to offer the Active Cruise Control (ACC) rider assistance system in the new R1250RT, giving motorcyclists a completely new, comfortable riding experience.
This article presents the new rider assistance system for motorcycles in detail and discusses the motorcycle-specific features that need to be taken into account when integrating the system into a single-track vehicle. Starting with the integration of the radar sensor into the front of the vehicle, the functional adaptations especially for cornering, and the challenging driving dynamics of motorcycles. The display and operating concept and the consideration of functional safety, which is a further focus of development due to the newly created interfaces to the engine and braking system, are discussed.
The article also provides an outlook on further assistance systems that could be introduced on motorcycles in the next few years. I.e. the expansion of environment sensor technology and the introduction of collision warning systems in both the front and rear areas of motorcycles.
ABS, which is essential for rider assistance systems, plays a central role in the new BMW Motorrad Active Cruise Control. In particular, the roll angle-dependent ABS functions and the full integral function are explained in more detail.
