Vehicle body roll angle, pitch angle, lateral acceleration, yaw acceleration and other parameters are important physical quantities describing vehicle behavior. These parameters are particularly important in research tests of active safety equipment and passive safety systems such as body stability control systems. NE has specially developed a body attitude test system for the field of automobile road testing. This system has comprehensive data collection, easy installation of equipment, rich host computer software functions, interface layout and user-friendly operation. It is a body attitude test, improving vehicle performance, and finding potential problems. And the ideal test equipment for objective evaluation of car sound performance.
