With radar technology, Bosch is opening a whole new chapter in motorcycle assistance systems: Among other things, it allows automatic speed and distance control. This pioneering innovation is now being used at BMW, Ducati and KTM.

In the Bosch vocabulary, the name is short and sweet ARAS – the acronym stands for Advanced Radar Assistance Systems. In the equipment lists of BMW, Ducati and KTM, on the other hand, there is talk of Adaptive Cruise Control (ACC), cruise control or adaptive cruise control. Nevertheless, the same thing is meant: a new generation of assistance systems that can also capture the motorcyclist’s surroundings.

ABS – the mother of all assistance systems

More than 30 years ago, BMW first offered an anti-lock braking system (ABS) for the K-100 series, heralding the age of electronic safety technology for motorcycles. ABS is now mandatory for all newly registered machines across Europe. The anti-lock system is practically the mother of all assistance systems, and on its triumphant advance up to the must-have equipment it has had a number of daughters: for example, traction control, which uses the existing ABS sensors (wheel speed) to prevent the rear wheel from spinning by regulating it intervenes in the engine control, i.e. taking the gas back accordingly. The same applies to the wheelie and stoppie control – also called rollover preventers.

Cornering ABS for motorcycles

Owing to the fact that 46 percent of all motorcycle accidents happen in curves, the Bosch accident researchers came to the conclusion years ago that the ABS should be expanded to include a mechanism for stability control. In 2013 – less than five years after the start of the MSC (Motorcycle Stability Control) research project – this type of ESP for motorcycles went into series production. In 2014, KTM was the first motorcycle manufacturer to use Bosch cornering ABS in the 1190 Adventure. In addition to the engine control, it includes the lean angle sensors (gyro sensor) in the control. Under normal conditions, this allows the driver to step safely into the irons even at an incline of 40 degrees, without the risk of falling due to excessive slippage. The trick: the brake pressure is reduced by the increasing lean angle. In the meantime, stability control has become almost standard equipment on new motorcycles – at least in Europe.

Slip preventer with cold gas

Bosch researchers are currently working on increasing cornering stability, for example when driving over oil stains, sand or wet leaves. They demonstrated to the public three years ago how this could work: The “Sliding mitigation” ignites so-called cold gas generators, such as those used in car airbags, as soon as the MSC sensors detect that the front wheel is slipping. The gas escapes with a bang through a side nozzle. The recoil generated in this way virtually compensates for the lost lateral guidance and pushes the machine back on track. Yes, we can! But at the moment the slip prevention device is still a dream of the future from Bosch accident research.

Radar-based assistance systems

With the implementation of radar-based assistants, the manufacturer is now going one step further in realizing the self-imposed three-stage security concept. ABS and MSC stand for accident avoidance and improvement of driving stability, ARAS now provides a precise picture of the vehicle environment, and the third stage is ultimately aimed at networking vehicles and traffic infrastructure. According to the Bosch accident researchers, radar-based assistance systems such as adaptive cruise control (ACC), blind spot warning systems and collision warning systems could prevent every seventh motorcycle accident. You are never distracted and, if necessary, always react faster than humans – the radar acts as the machine’s sensory organ. The technology behind it: a combination of radar sensor, braking system, engine management and the interaction between man and machine.

If the driver does not react to a critical approach to the vehicle in front, a visual warning is given, but no braking intervention.

What sounds so simple now was a huge challenge for the developers. Although the application originates from the car like so many other things, the transfer to the two-wheeler turned out to be far more demanding. As banal as it may sound, a motorcycle is not a car. Starting with completely different input parameters for the driver’s position, steering characteristics, driving dynamics, braking behavior and operating conditions, right up to more cramped accommodation options for the radar sensors.

ACC also marks a milestone in that, for the first time, the system actively supports the driver with controlled deceleration to maintain a constant safety distance. One thing is clear, however: In emergency situations, the driver has to brake himself as much as he can, as a limited delay is stored in the system, which is not nearly as effective as in the car.

The distance radar is part of the standard equipment of the KTM 1290 Adventure S. BMW charges a surcharge of 500 euros for this extra safety feature on the R 1250 RT. And in Ducati’s Multistrada V4 S, the cruise control is combined on top with a blind spot warning – but only available in a package with side case, main stand, heated grips and heated seats at a slim price of 2,150 euros.
