AN ESTIMATION OF AERODYNAMIC DRAG COEFFICIENT OF A PASSENGER CAR BY COAST-DOWN TESTS IN WINDY ENVIRONMENTS

Kenji Hamabe, Kozo Kitoh, Hiroyuki Ogata, Toshio Kobayashi

Open publisher page 9 citations

Abstract

In this paper, the aerodynamic drag is separated from the total drag acting on a passenger car during coast-down in windy environments by using the least square method. The coefficients for the rolling resistance of tires and the losses in the driveline are determined to minimize the variations of aerodynamic drag coefficients over the yaw angle ranges tested and the aerodynamic drag coefficient is expressed in terms of yaw angle.
