A vehicle system includes a sensor that outputs an impact signal and a processing device that is programmed to calculate an acceleration envelope from the impact signal, determine a number of times the impact signal crosses a predetermined threshold, and determine whether the impact signal represents a pedestrian impact. Whether the impact is a pedestrian impact is based at least in part on the acceleration envelope and the number of times the impact signal crosses the predetermined threshold.
