New international study shows autonomous emergency braking can reduce the risk of hitting the back of another car by 38 per cent.
A study commissioned by ANCAP, the Commonwealth Department of Infrastructure and Regional Development and Euro NCAP has found that autonomous emergency braking (AEB) can reduce the likelihood of hitting the back of another car by up to 38 per cent.
An increasingly common safety feature in new cars, AEB works by monitoring 6m to 8m ahead of a car and automatically applies the brakes if it detects an obstacle in the way – at speeds of up to 50km/h with current technology.
The number of times they were striking cars in front was reduced significantly
Car crash data from six countries was combined by the researchers to compare crashes between cars fitted with AEB with those without, across accidents where the car was either striking a car in front or was being struck from behind.
In non-AEB cars, the split between striking and being struck was close to 50-50. In cars with AEB, the number of times they were striking cars in front was reduced significantly.
The researchers also noted that AEB-fitted cars may be more likely to be struck from behind, as an unintended consequence of AEB’s better reaction time, compared to a human driver. They do note, however, that more study into this particular area is required.
Also requiring more research is the application of high-speed AEB systems designed for highway use, as the study only focussed on systems that work below 50km/h.
