<p>An automatic gear shifting control device of a vehicle includes a control part 60 for executing an automatic gear shifting operation in response to at least vehicle-speed information, sensors 51, 52 for detecting the rotational speeds of a front wheel WF and a rear wheel WR, and a speed difference detection means 63 for detecting the difference in rotational speed between the front wheel WF and the rear wheel WR based on information from the sensors 51, 52. The control part executes automatic gear shifting control in response to the vehicle-speed information calculated based on the larger of the two rotational speeds when the difference in rotational speed is detected. Even if the wheel from which the vehicle speed is detected is locked or the rotational speed of the wheel is sharply lowered, the control part can execute an appropriate automatic gear shifting control conforming to an actual vehicle speed.</p> |
