Dynamic gear state change detecting method for use in motor vehicle, involves calculating state variables of gear from speed signals for diagnostics purpose, and evaluating measurement signals to simulate physical system performance of gear
摘要
<p>The method involves calculating state variables of a gear from speed signals for diagnostics purpose, and evaluating the measurement signals in a gear model. The evaluation of the measurement signals simulates the physical system performance of the gear. The deviation of measured variables from variables calculated in the gear model is used for detection change of system parameters.</p>
