On-Track Vehicle Dynamics Testing – Obstacle Avoidance and Double Lane Change Test

Abstract

Evaluating the behavior of vehicles passing through a corner is a very important task in the testing of passenger vehicles, i.e. in assessing the ability of vehicles to maintain the specified direction ofmovement. Some of the most important tests that evaluate these vehicle characteristics are the so-called severe lanechange maneuver tests: double lane change test or obstacle avoidance test. ISO 3888-1 and ISO 3888-2 standards define the test track dimensions and conditions under which tests are performed. This paper describes the method of performing the mentioned tests on the example of theBMW650i 2014 vehicle, the equipment used for the test, and the comparison of the obtained results for various conditions. The results of measurements include pitch, roll, yaw rate, and acceleration of the vehicle body. Lateral acceleration and longitudinal velocity of the vehicle are also shown for every test.
