Abstract
The experimental campaign discussed in publication 2019-01-0635 was extended to emulate more vehicle parameters and also to increase severity leading to deployment event. The engine speed (RPM) and Accelerator Pedal Position (APP) were emulated using LabVIEW and added to the previously reported emulated parameters of wheel speeds and brake status. Overlapping non-deployment events were generated and the EDR data is presented enriched with additional (faster) CAN bus data sniffed from the vehicle harness. While the non-deployment events were still generated using the rubber mallet in pendulum configuration as in 2019-01-0635, a series of tests were performed using an Izod pendulum to incrementally increase event severity until deployment event was generated. The Izod pendulum was instrumented with a rotational potentiometer to measure its instantaneous angle while laboratory accelerometers were used to separately measure acceleration. The Air bag Control Module (ACM) was mounted in a box whose inertia was increased by using sand bags and hit by the Izod pendulum whose weight was increased by an additional 18kg. The Izod pendulum impact produced a very short crash pulse and extensive development was required to lengthen the crash pulse to better represent real world crashes, using crushable foam together with adjustable hydraulic piston as damping.
