PROBLEM TO BE SOLVED: To improve responsiveness to an operator input by receiving a desired speed signal and an actual speed signal, judging time when an operator requests a rapid change and generating an acceleration command based on a jerk value beyond a prescribed jerk limit in response to a rapid change. SOLUTION: A transmission assembly 10 having a mechanical transmission 14 and a continuously variable transmission 16 is provided with a controller 18 and a command input structure 22. In the command input structure 22, a speed input mechanism 60 including a speed pedal 62 is provided and a speed signal showing desired speed is obtained. A direction control mechanism 64 movable from a neutral position to a forward/reverse position, a jerk input part 71 transmitting a jerk signal showing a jerk value (j) and a maximum acceleration input part 73 are provided. By the controller 18, command speed and actual speed by a speed sensor 80 are processed, a command signal is obtained, and a pump and motor displacement actuators 50, 58 are controlled. |
