Volkswagen leads as first van manufacturer to fit AEB as standard
Volkswagen is to become the first commercial vehicle brand to fit all its vans with autonomous emergency braking systems (Front Assist with City Emergency Braking), meaning all customers ordering a new Caddy, Transporter or Crafter van from 1 June will be guaranteed safety as standard.
According to Thatcham Research, the motor insurers’ automotive research centre and respected experts in safety, security and crash repair, autonomous emergency braking (AEB) systems are ‘probably the most significant development in vehicle safety since the seat belt’ and have the potential to save more than 100 lives and 120,000 casualties over the next ten years.
Not only does autonomous emergency braking have the potential to reduce the number and severity of accidents, it has also been proven to cut third party injury insurance claims by 45 per cent. For van drivers and fleet operators, this means lower costs as well as less downtime thanks to fewer crashes and therefore drivers and vans kept on the road – and working – for longer. In addition, vehicles fitted with autonomous braking systems have an average insurance premium reduction of ten per cent compared to those which don’t.

How does it work?
Using a radar built into the front end of the van, Front Assist recognises critical distances to the vehicle in front and helps to ensure safe stopping. In any dangerous situations Front Assist reacts here in two stages: in the first the assistance system warns the driver with audible and visual signals of any vehicle in front driving slowly or suddenly braking and of the associated risk of collision. In parallel it gets the vehicle ready for emergency braking – by applying the brake pads and alerting the brake assistant. If the driver fails to react to the warning, a one-off short jolt of the brake indicates in the second stage the looming danger of a collision and the brake assistant’s responsiveness is further increased. If the driver then hits the brakes, full braking power is immediately available. If the driver does not brake strongly enough, Front Assist increases the braking pressure to the required level, so that the vehicle comes to a stop before reaching the obstacle.
The system also includes the City Emergency Braking function, which provides assistance at low speeds of under 18 mph. If the driver fails to see or react to an obstacle, the system automatically applies the brakes and ensures that the speed of any collision is reduced. Ideally, it completely prevents the vehicle from running into the obstacle.
Three quarters of collisions occur in so-called city environments (at under 25 mph) and a 2015 study by Euro NCAP and Australasian NCAP showed autonomous braking leads to a 38 per cent reduction in real-world rear-end crashes.
