The new, fifth generation of radar sensors from Continental, which features advanced object recognition, enables the implementation of an emergency brake assistant that specifically meets the need of motorbike riders. Experience with safety systems from the passenger car and commercial vehicle sectors has been incorporated into the development of the two-wheel system. But there are differences: While in a car such an assistant autonomously performs emergency braking with maximum braking force to avoid a collision, the motorcycle system reduces speed in a much more controlled manner. It is designed more to support the driver than to take control.

With the aid of a radar sensor, the emergency brake assistant monitors the area in front of the motorcycle. If there is a danger of a collision with a vehicle in front or another obstacle, the driver is first warned: visually, acoustically or haptically, for example by vibrations in the handlebars. A low pre-braking pressure then supports the driver during the active braking process. If the driver does not react to the warning, the Emergency Brake Assistant automatically builds up braking force – provided both hands are on the handlebars. The braking deceleration is considerably lower than is usual in a car emergency braking system.


“Unlike in a car, on a motorcycle you are largely exposed to environmental influences such as wind, weather and vibrations. As a result, motorcyclists are more likely to find themselves in situations where it is difficult to assess the speed of other road users. The Motorcycle Emergency Brake Assistant is therefore primarily indicative in character: it draws the driver’s attention to critical situations and makes them easier to understand,” says Christian Pfeiffer, Project Manager ARAS for the 2-Wheeler & Powersports division at Continental. As with the car, the system reduces the speed here as well. But the goal is to initiate a process that the driver then controls. This shortens the reaction time and the stopping distance can be considerably reduced.

A key component for the emergency brake assistant is Continental’s new 5th generation radar sensor. With improved object detection algorithms, the sensor can also detect smaller objects that may already be relevant for a motorcyclist. In addition, the so-called elevation measurement capability allows the height of objects to be determined. This enables the sensor, for example, to detect traffic jam ends under a bridge or road boundaries such as kerbstones even better.
