Frankfurt am Main, Germany, The international automotive supplier Continental has convinced another European vehicle manufacturer to adopt its proximity sensor for the Emergency Brake Assist (EBA) city version for the prevention of rear-end collisions. The sensor system monitors the road ahead of the vehicle and is networked with the braking system. It automatically applies the brakes if there is a risk of a nose-to-tail collision and the driver either fails to react or his reactions are too slow. Continental supplies the infrared sensor, which monitors the road ahead and detects hazards, and the electronic braking system, both of which are core components.
Preventive intervention at speeds of up to around 30 km/h The risk of rear-end collisions is particularly great in city traffic with its constant alternation between braking and accelerating. 75 percent of accidents recorded by the police occur at speeds below 30 km/h. It is precisely at these speeds, in slow-moving or in "stop and go" traffic, that this sensor system, developed and produced by Continental based on the Closing Velocity (CV) sensor, reduces the risk of a rear-end collision. Fitted level with the inside mirror in the area cleaned by the windshield wiper, this sensor uses three laser beams to scan the road conditions ahead up to a distance of around eight meters. The sensor picks up vehicles which are stationary or traveling in the same direction. If the gap is less than the distance regarded as critical at the current speed, the system applies the brakes automatically.
If the maximum speed differential between the vehicles was 15 km/h, a rear-end collision would be avoided in most cases. And, at greater relative speeds, the severity of the impact would be considerably mitigated. At the same time, the system optimizes occupant protection by providing additional data to the airbag control unit and triggering the restraint systems as required. Dr. Ralf Cramer, President of the Chassis & Safety Division and member of the Executive Board at Continental: "Tailor-made solutions for all vehicle classes and applications are ideals that we make possible with our scalable modules. The adoption of this system by another manufacturer brings us a significant step closer to our 'safety for everyone' target and will prevent numerous accidents and injuries."
