By its shorter reaction time emergency brake systems can reduce the stopping distance significantly. As a result, accidents can be avoided or at least the consequences of an accident can be minimized.
Emergency Brake Assist
The ARAS™ function “ Emergency Brake Assist“ (EBA) detects critical traffic situations and ensures an optimum use of the available braking power. Therefore, the area in front of the motorcycle is continuously monitored. Taking the tilt angle into account, the sensor measures the distance to the detected object as well as its speed. When a rear-end accident threatens the motorcyclist will be alerted first, before the EBA function support his active braking with a slight pre-brake pressure. If the rider does not respond to the alert, the emergency brake assist starts to build up brake pressure autonomously. A necessary prerequisite for this is that the rider has both hands on the handlebar.
Forward Collision Warning
As a preliminary stage to the EBA, the ARAS™ function ” Forward Collision Warning” (FCW) is meant to avoid accidents caused by inattentive riders by means of optical and haptic alerts. A forward facing radar sensor or camera sensor detects, classifies, and positions preceding traffic. The sensor is able to measure the way to the detected traffic object by taking into account the motorcycle´s lean angle. In doing so, it warns the motorcyclist if a collision is imminent. When vehicles approach quickly or strong deceleration is required, the motorcyclists´ miscalculations often leads to accidents. By using the FCW function this can be avoided.
