摘要： An earth working vehicle which has an internal combustion engine and a driveline for establishing a driving relationship between the internal combustion engine and wheels of the earth working vehicle. The driveline includes a mechanical CVT. The earth working vehicle also has a control for manual operation by a driver of the earth working vehicle, the control operable by the driver to select among at least two modes of operation, namely a first mode of operation and a second mode of operation, the selection of the first mode of operation corresponding to a command to cause the vehicle to move forward, the selection of the second mode of operation corresponding to a command to cause the vehicle to move backwards. The earth moving vehicle also has an electronic controller. While the vehicle is in motion, the electronic controller is responsive to a change of a mode of operation made via the control and indicating a command to reverse a direction of travel of the vehicle, to issue a control signal to the mechanical CVT to cause the mechanical CVT to downshift.
