Brake assist systems and autonomous emergency braking systems were able to avoid vehicle-pedestrian crashes 12 percent and 42 percent of the time, respectively.

Experience with brake assist systems and autonomous emergency braking systems in a 50-crash sample from Spain.


Summary Information

This paper investigates the effects of two active safety systems, a brake assist system (BAS) with anti-lock brakes (ABS) and Daimler Chrysler’s PROTECTOR autonomous emergency braking system (AEB), to reduce the number of vehicle-pedestrian collisions. The paper describes how the technology works and how the project reconstructed 50 vehicle-pedestrian conflicts virtually simulating the effects the results had the braking systems been implemented.


The study evaluated 50 vehicle-pedestrian collisions in PC-Crash, a simulation software. With the software each crash was reconstructed under the actual conditions and simulated with the active safety systems. The methodology was established to encompass into one optimal procedure to investigate on the spot every single accident, perform reconstructions and simulations, and analyze the obtained data and the results.

  • Avoiding a collision with a pedestrian entirely was found to be possible 12 percent of the time with the BAS system with ABS and 42 percent of the time with the PROTECTOR system.
