Low speed autonomous emergency braking (AEB) can reduce rear-end crashes by 38 percent.

A study was conducted to evaluate the effectiveness of low speed AEB technology in passenger vehicles, based on real-world crash experience.

Effectiveness of low speed autonomous emergency braking in real-world rear-end crashes

Summary Information

Advanced crash avoidance technologies are increasing rapidly in passenger and commercial vehicles as industry, government and the community focus on improved vehicle safety systems. One of the more promising safety technologies that is starting to appear as standard equipment on modern passenger cars and sport utility vehicles is autonomous emergency braking (AEB). Autonomous emergency braking systems apply the vehicle brakes when a collision is eminent in spite of any reaction by the driver. In some technologies, the system forewarns the driver with an acoustic signal when a collision is still avoidable, but subsequently applies the brakes automatically if the driver fails to respond.



The validating vehicle safety through meta-analysis (VVSMA) group comprising a collaboration of government, industry consumer organizations and researchers, pooled data from a number of countries using a standard analysis format and the established MUND approach. Induced exposure methods were adopted to control for any extraneous effects. Areas requiring further research were identified and widespread fitment through the vehicle fleet was recommended.

FINDINGS

  • The findings showed a 38 percent overall reduction in rear-end crashes for vehicles fitted with AEB compared to a comparison sample of similar vehicles.
  • There was no statistical evidence of any difference in effect between urban (<60km/h) and rural (>60 km/h) speed zones.
