Authors Abstract
Content
The accuracy of the Powertrain Control Module (PCM) Event Data Recorder (EDR) was tested on a 2009 Ford Crown Victoria Police Interceptor during both straight line steady state conditions and maximum ABS braking, at the Michigan State Police training facility in Lansing, MI. Six runs were made starting from 64 km/h (40 mph) and six runs starting from 96km/h (60 mph). Data was collected from the PCM EDR and the primary speed reference instrumentation was a Racelogic VBOX III (with IMU) 100 Hz differential GPS speed data acquisition system. On selected runs Radar was used as additional steady state speed verification and for the braking portion a Vericom 3000 was used to verify speed loss and calculated stop distance. Visible ABS tire marks were documented following each test, and the length of marks was compared to the calculated braking distance from each measurement device. Graphs of PCM speed/brake/accel pedal data versus VBOX speed over time are presented. The differences between PCM and VBOX are plotted and analyzed statistically, separated into steady state and braking conditions.
