TY - JOUR PY - 2014// TI - Acceleration testing and modeling of vehicle kinematics under idle conditions JO - SAE International journal of transportation safety A1 - Randles, Bryan A1 - Voss, Daniel A1 - Ikram, Isaac A1 - Furbish, Christopher A1 - Welcher, Judson A1 - Szabo, Thomas SP - 240 EP - 256 VL - 2 IS - 2 N2 - Determination of vehicle speed at the time of impact is frequently an important factor in accident reconstruction. In many cases some evidence may indicate that the brake pedal of a striking vehicle was disengaged, and the vehicle was permitted to idle forward prior to impacting the target vehicle. This study was undertaken to analyze the kinematic response of various vehicles equipped with automatic transmissions while idling, with the transmissions in drive and the brake pedals disengaged. An array of sedans, SUV's and pickup trucks were tested under 3 roadway conditions (flat, medium slope and high slope). The vehicle responses are reported and mathematical relationships were developed to model the idle velocity profiles for flat and sloped roadway surfaces.
