ENGINE REVOLVING SPEED CONTROL DEVICE FOR HYDRAULIC DRIVEN VEHICLE

摘要

PURPOSE:To instantly reduce the revolving speed of an engine without performing the slowdown control even though a pedal is stamped momentarily and set free at the time a vehicle is stopped in case the setting is such that the engine revolving speed is subjected to slowdown control during running deceleration. CONSTITUTION:A controller 33 is provided with a deceleration judging means, which judges that the stamping amount of a running pedal 6a has decreased, and a stamping time judging means which judges that the pedal has been stamped over the specified time. If declarative operation is made in this condition that the pedal has been stamped over the specified time, the revolving speed of the engine will reduce at least with the elapse of the time. No slowdown control will be made even though the decelerative operation is introduced in case a momentary light stamping is applied to the pedal.
