Abstract:
1. 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 speed-changed power, the system comprising: a speed changing control unit for setting a speed change ratio of the speed changing device; an engine control unit for setting an engine rotational speed of the engine; an operational instrument for delivering an operational instruction in response to a driver's operation; and a speed changing module, wherein based on said operational instruction, speed changing module is configured to provide said engine control unit with a rotational speed reducing instruction for reducing an engine rotational speed set by said engine control unit by a predetermined amount, and wherein said speed changing module is configured also to request, to said speed changing control unit, a change of the speed change ratio for compensating for said reduction in the engine rotational speed by said rotational speed reducing instruction so as to maintain the vehicle speed.
