A finely tuned system of suspension, engine management, brakes and tyres combined with an array of electronic measuring devices – all with one single objective: to keep the BMW 3 Series Sedan safely on track in the most demanding situations. Because giving the driver maximum control means ensuring maximum safety.
Active Protection is enabled shortly after the vehicle sets off – above a speed of 18 km/h – and automatically tightens the seat belt slightly. If a critical driving situation arises, the tension of the front seat belts is reversibly increased while the side windows and sunroof are closed. Active Protection detects the threat of a collision via the front camera or front radar, by all-out braking initiated by the driver or if the vehicle shows strong signs of understeering or oversteering.
To prevent hazards from arising in the first place, the attentiveness assistant monitors driving behaviour for symptoms of fatigue. The systems analyses the driver’s steering behaviour and reacts to any irregularities: by recommending a break in the Control Display.
If a crash was unavoidable, the system applies the vehicle’s brakes automatically and brings it to a standstill, without the driver needing to act. This reduces – or in an ideal case completely rules out– the probability of secondary of follow-on collisions and their consequences.
