The paper reports test results for accuracy of pre-crash speed, brake, and accelerator pedal position data recorded in a new family of Ford RCM EDR’s under steady state conditions. The authors drove 2 test vehicles at 3 different speeds from 48 to 113 km/h (30 to 70 mph), and artificially created EDR events so pre-crash data would be stored. The authors collected RCM data and PCM data. A GPS based Racelogic VBOX was used to measure speed and record CAN bus information real time. Maximum error, average error, and 98% confidence intervals are reported for RCM to VBOX and PCM to VBOX. Accelerator pedal position accuracy and brake on/off reporting latency of the RCM to CAN bus data and/or auxiliary brake switches are documented.
