An in-vehicle inertia test platform for dynamics control system

To support vehicle dynamics controller development, verification and evaluation, an independent practical in-vehicle inertia test platform(ITP) has been developed to measurement and monitor vehicle dynamics states. In this paper, the basic principle of the proposed inertial measurement unit is explained, the system architecture of the ITP is proposed, as well as the main functionality of software is given. As a typical test result, an antilock brake system (ABS) performance assessment is provided to illustrate that a fast and accurate measurement of the vehicle longitudinal acceleration, lateral acceleration, yaw rate and roll rate can be obtained with a proposed test scheme.
