摘要： PROBLEM TO BE SOLVED: To determine gear shift points (shift down/up points) so that economical power running operation is performed.
SOLUTION: A transmission controller 13 checks on whether a brake signal is outputted from a hydraulic switch 19 (S41) or whether an accelerator pedal operation signal is outputted from an accelerator pedal 17 (S43). The controller also checks on whether any engine mode signal is outputted from a mode selector switch SW21 (S45). When the controller determines that the accelerator pedal operation signal is outputted and the accelerator pedal 17 is operated, it sets one of high power/economy modes according to the selection by a driver. When the controller determines that the accelerator pedal 17 is not operated, it sets the traveling mode in the retarder mode when the brake signal is turned on, and sets it in the coasting mode when the brake signal is not turned on.
