Car-to-bike communication
Safe in the network

The idea: networked vehicles communicate with each other regardless of brand and can warn themselves and their drivers of dangers. But only a common standard ensures that a tractor can also be a motorcycle “to understand” can.

Connected Motorcycle Consortium or CMC for short. This is the name of a working group in which leading motorcycle manufacturers define a new safety technology: the networked motorcycle. Networked vehicles communicate with each other regardless of brand and can warn themselves and their drivers of dangers. The exchange can take place via WLAN or 5G technology. Important data such as position, vehicle type, direction of travel, speed, strong braking maneuvers, interventions by stability controls or other driver assistants should be exchanged. But anonymized, encrypted, not manipulable or storable. What is important for the CMC is that motorcycles must also play a role in the discussion of connected traffic. “The goal is a common standard.” This is the only way to ensure that the tractor turning off the oncoming motorcycle “to understand” and as a result can warn the driver of the danger. “This would prevent 70 percent of all intersection accidents”, says a CMC spokesman.

How safe will we be riding a motorcycle tomorrow? The key to success: connected driving in a digital world.

But there is still a long way to go. There are hardly any cars with this technology and with driver assistants the motorcycle is still quite naked. Since the driver assistants, with their semi-autonomous interventions in gas, brakes and, where possible, the steering, are the basis for V2X communication, a few more model generations of networked motorcycles will pass. A part of the development that should not be underestimated is how the motorcycle warns of dangers or ensures that the person in the saddle is ready for a semi-autonomous intervention.

The motorcycles shouldn’t change much. The smart bike of the future should only look like that “interface” differentiate. This is the interface between technology and people, through which the driver receives a warning in the event of danger. With the prototypes here on the right, this is done optically via an additional display in the cockpit.

The network is independent of cell phone networks or data cloud, consists only of the data sent by the vehicles. Range: 200 to 1000 meters. After the vehicle-to-vehicle communication, traffic lights or level crossings are to be added in a second step “have a say” allowed to.

The technique: Two motorcycle cases are still full today and should soon fit into a small, black box. Its content essentially: a high-precision GPS, a processor for generating the WLAN signal and a router plus an antenna for sending and receiving. It must be placed as high as possible without ever being covered.

Comment from Jens Kratschmar (40), MOTORRAD editor and, among other things, also damaged left-turners: “There are two reasons why you are reading my lines here. On the one hand, colleague Mike Schuhmann is injured in the hospital: a driver took him and his ankle head-on. Get well soon, Mike. On the other hand, I was also taken on the radiator by a left turn. My left foot was crushed on the engine block. Mike could write to you today instead of mine and I might have become a foot model after all: If there were already techniques like the ones that the CMC is developing for motorcycles and us. My appeal: These systems shouldn’t take our driving away from us at all, but rather allow us to do so safely under adverse conditions. Just ask Mike’s ankle and my foot for their opinions on this. Ride safely!”
