Accuracy of Recorded Driver Inputs in Toyota Part 563 EDR 2014-01-0505

Four Toyota vehicles were tested in 12 test conditions to compare the Event Data Recorder (EDR) results with data gathered from onboard test instrumentation and the test protocol. The four Toyota vehicles tested were 2013 Model Year (MY) vehicles with EDRs that meet 49 CFR CH. V Part 563. While the previous Toyota EDR versions captured four pre-crash parameters, this generation Toyota EDR (12EDR) includes additional operating parameters and a faster sampling rate before the event trigger, including additional parameters not required by Part 563.
The main focus of this research was to analyze the recording of the following driver inputs: accelerator pedal application, brake pedal application, steering wheel angle, and cruise control activation. The EDR-recorded inputs were compared with the values on the HS-CAN. The test results indicate that the 12EDR accurately recorded these driver inputs.
