<p>PURPOSE: To provide an automated adaptive upshift control device continuously renewing the value of a control parameter showing the deceleration of a vehicle by deciding the feasibility of selected upshift and starting the upshift only in deciding it feasible. CONSTITUTION: A transmission system is provided with an engine E, a fuel throttle device P, an input shaft 16 drivablly connected by the engine E via a main friction clutch C, an output shaft 90 connected to a drive wheel of a vehicle, and a multi-stage gear transmission 10 with a control unit for receiving input signals. The control unit calculates the engine speed changes in the whole period till the engine speed is reduced to the synchronous speed during each upshifting. The present engine deceleration is processed by the control parameter set beforehand and the processed value is used as a new control parameter so that the feasibility of the upshift is decided.</p> |
