Automatic Braking Could Save Countless Lives

Autonomous Emergency Braking Explained

Autonomous Emergency Braking systems could reduce the number of people killed or seriously injured on the road by seventeen thousand over ten years, Thatcham has claimed. This assumes it is fitted to every new vehicle from 2015. The impact of such technology could, therefore, be comparable to the benefits felt in the eighties when legislation first required motorists to wear seatbelts. There was then a fifty percent reduction in casualties in a short period. Autonomous Emergency Braking – or AEB – comes in various forms and each manufacture has its unique twist on the recipe. In general terms, however, it works by monitoring the road ahead via laser/radar then calculates the stopping distance to the nearest hazard. This might be a lorry, etc. If the distance becomes to small – perhaps because the motorist fails to notice that the hazard is losing speed - the system typically warns him/her via a beeping tone and warning light. If the motorist fails to react - perhaps because he/she panics or is distracted – it can override the driver and perform a full-power emergency stop. This has one of two effects. Either the vehicle misses the hazard completely or the severity of the impact is reduced. The latter – at the very least – minimises personal injury and the cost of repair to cars, etc.

Blind Spot Monitoring, Lane Departure And Attention Assist

But there is more to modern vehicles than automatic braking systems. Blind Spot Monitoring – which again is available in various forms from various manufacturers – makes changing lane significantly safer. In general terms, the system presents the motorist with a warning light in the wing mirror when a vehicle is concealed. Blind spots, of course, are typically caused by rear pillars, etc. Warning lights enable the motorist – even if the vehicle is completely obscured – to recognise there is a hazard and maintain a safe line. And there is more. If the motorist signals to change lane when the light is illuminated, it might flash to emphasis the risk. There might be a beeping tone too. Very clever. Lane Departure Warning, in contrast, scans the road for lane markings. It can then inform the motorist that the vehicle is wandering off line (perhaps because the driver is distracted). Advanced systems automatically steer back to the intended route. This is emphasised by a buzz in the steering. Furthermore, Attention Assist scans for signs of fatigue. These systems – again, in general terms – recognise that when a driver is alert there are consistent, small, steering movements. As such, a lack of input followed by a sharp correction suggests tiredness. The vehicle then recommends rest via its dashboard.


This is only the tip of the iceberg..when peer to peer traffic networking comes in, along with vehicle communications(cars talking to each other so they know where each other is)it will significantly reduce accidents. @davidement, couldn't agree more!lol @mikeaston bmw's have had variable brake lights for years,my 2002 e46 m3 has them.

I note the car has blacked out windows. Very safe, I'm sure.

Seat belts for drivers increased the accident rate by reducing injury to drivers making them feel safer. A cheese wire round the drivers throat would decrease accidents overall (and be much fairer to others).

Several years ago i thought that a variable brake light when stopping quickly would prevent rear end collisions ie when a g sensor showed you were breaking hard the stoplights would pulse or get much brighter
