Volvo Trucks - Demonstration of Collision Warning with Emergency Brake


Recommended Posts

Volvo Trucks Press Release  /  November 7, 2017

The aim is to reduce accidents in which a truck drives into the back of a vehicle in front of the truck, an accident scenario that accounts for about one-fifth of all road accidents involving trucks.

As of November 2015 there is an EU-wide legal requirement for new two- and three-axle heavy trucks to be equipped with the function automatic emergency brake.

At present, legislation requires that the emergency braking system must reduce the trucks speed by 10 km/h.

Next year, this will be tightened to 20 km/h.

Volvo Trucks has developed a system that goes well beyond both current and future legal requirements. The emergency brake is only used if it is absolutely necessary, and it is deployed extremely quickly. The braking speed – or retardation to use the correct technical term – is about 7 m/sec2, which is on par with what many passenger cars can manage. In practice this means that the truck’s speed can be cut from 80 to 0 km/h in about 40 metres.
