The Side View Assist is the World’s first rider assistance system for two-wheelers. This is a Blind Spot Warning system, which uses four ultrasonic sensors to monitor the surrounding of the rider. Whenever there is a vehicle (i.e. a car, truck, or another motorbike) in the rider’s blind spot, the technology warns the rider with an optical signal close to the mirror. This will allow the rider to avoid a collision when changing lanes.
In the current vehicle application, Side View Assist is active at speeds ranging from 25 to 80 kilometers per hour and supports riders whenever the difference in relative speed to other road users is small. The system helps to improve safety especially in cities, where heavy traffic makes it necessary to change lanes more often.
Originally such systems have been developed for cars and different system solutions for cars have been in serial production for several years. The challenge was to adapt these systems so they would work for two-wheelers as well.
Using the system components of car solutions is highly beneficial, because the hardware as well as the corresponding software already exists. However, adapting car components to motorcycles generated new problems for the developer:
- lean angle;
- ultrasonic noise generated by the motorcycle itself;
- installation of the ultrasonic sensors; and
- high vibration at the fixation of the ECU (Electronic Control Unit) compared to cars.
