摘要： A speed change system for work vehicle having a continuously variable transmission device selects a first change gear ratio which is set larger than a smallest change gear ratio, when an engine rotational speed is a first set rotational speed which is set equal or close to an idling rotational speed of an engine; retains the change gear ratio of the continuously variable transmission device at the smallest change gear ratio, when the engine rotational speed is equal to or above a second set rotational speed set on a high-speed side relative to the first set rotational speed; and makes the change gear ratio of the continuously variable transmission device larger between the first change gear ratio and the smallest change gear ratio, as the engine rotational speed at that moment becomes lower, when the engine rotational speed is between the first and second set rotational speeds.

摘要： A speed changing control system for a vehicle including a speed changing device for speed changing a rotational power from an engine and outputting the resultant power, a speed changing control unit for setting a speed change ratio of the speed changing device, and an engine control unit for setting an engine rotational speed of the engine. Based on an operational instruction in response to a driver's operation, a rotational speed reducing instruction is given to the engine control unit for reducing an engine rotational speed set by the engine control unit by a predetermined amount. Also, a speed changing ratio changing instruction is given to the engine control unit for requesting, to a speed changing control unit, a change of the speed change ratio for compensating for the reduction in the engine rotational speed by the rotational speed reducing instruction so as to maintain the vehicle speed.
