Abstract
A system for detecting an operating state of an automobile free-wheel hub mechanism used for connecting and disconnecting a driveshaft to and from a wheel hub by engaging and disengaging a fixed gear firmly connected to the driveshaft for rotation with the driveshaft with and from a movable gear slidably splined to the inner periphery of a cylindrical housing of the wheel hub, comprises sensors for detecting a revolution speed of a road wheel having the wheel hub to generate a wheel-speed indicative signal, another sensors for detecting a revolution speed of the driveshaft to generate a driveshaft revolution-speed indicative signal, and a controller for detecting an operating state of the free-wheel hub mechanism on the basis of a deviation between a value of the wheel-speed indicative signal and a value of the driveshaft revolution-speed indicative signal.
