Dynamic inclination detecting device for automotive dynamic driving simulator and method thereof

The invention discloses a dynamic inclination detecting device for an automotive dynamic driving simulator, which comprises two acceleration transducers, a signal conditioning circuit, a microcontroller, a data processing module, a communication circuit and an upper computer. The invention discloses a detecting method using the dynamic inclination detecting device, which is characterized in that probes of the two transducers are arranged on a detected object and a movement carrier of the detected object in the same posture respectively, and the arranging positions are as close as possible so that the two transducers are approximately positioned in one rigid body. Meanwhile, three-dimensional acceleration signals on the detected object and the carrier are extracted; data fusion and processing are performed on the two groups of signals to remove common-mode signals of common vibration, rotational inertia, posture change and the like; and the different-mode signals of the taper angle change of the relative movement carrier of the detected object are reserved so as to acquire the angle variable of the relative carrier of the detected object. The device and the method are used for detecting the angle or the taper in the dynamic carrier, and expand the application range of the acceleration transducers.
