The triggering algorithm

The triggering algorithm is the true "brain" of the system, being able to distinguish normal riding from crash conditions, something which is very difficult to achieve.

The effectiveness and safety of an airbag system is largely determined by the quality of the triggering algorithm, which must be able to distinguish between incipient fall conditions and normal use conditions, including sports use. Conditions that can lead to a fall arise when the front wheel starts to slide during braking on a bend, or when the rear wheel loses traction coming out of a bend. The motorcycle-rider system, which was formerly in equilibrium, becomes unbalanced. This phenomenon is the key to the triggering algorithm.

The triggering algorithm is the true "brain" of the system, being able to distinguish normal riding from crash conditions. That's something which is very difficult to accomplish, both on the track, where bikes can reach lean angles of over 50°, and on the road, where the system needs to achieve an extraordinarily short deployment time.

As a result it required a tremendous investment in terms of time, people and equipment to perfect the triggering algorithm. The D-air® system benefits from algorithms that can be calibrated to meet different needs and has been tested extensively in the laboratory, on the road and by the prestigious German certification organisation Tüv Süd.
