![]() ![]() The technology doesn’t know the condition of your tyres and suspension, and therefore your overall braking ability.AEB doesn’t necessarily react much quicker than you could as it’ll warn you first and will only brake as a last resort.Some systems will look ahead 200m and can identify a potential issue well in advance of the average driver.īoth systems are becoming common on cars because they are needed to score a maximum EuroNCAP crash test score, and also have been introduced on trucks and buses. Radar, cameras or a mixture of both are used to look ahead and determine what is happening. If AEB can shave a second off your reaction time, you’ll have 31.3m extra to play with and that could mean the difference between hitting the obstacle at around 35mph, or stopping completely. From 70mph it could take upwards of 90 metres to stop, meaning your total stopping distance will be around 150m. Therefore if there’s an incident ahead on the motorway, you’ll cover at least 31.3 metres and probably more like 60 metres before your foot even hits the brake. Younger people might have faster general reactions but not the experience to make the decision quickly enough, while older people have slower reactions but more experience.Īt 70mph we’re covering 31.3 metres per second. Typically this is between 1-2 seconds depending on your age and experience. The amount of time you take from first seeing the hazard to taking action is the reaction time. While our brains are evaluating these inputs we continue to travel towards the hazard. What is the appropriate action to take (brake, swerve, brake and swerve, nothing, accelerate, etc).how fast are you travelling, what type of road surface, etc) ![]() you may not have seen an escaped zoo elephant in the road, but it’s obvious that it could present a problem in the very near future)
