摘要:
In a work vehicle according to the present invention, a control device calculates, for each of a plurality of speed-changing stages in a PTO transmission, an expected maximum rotational speed of PTO rotary power that is output from the PTO shaft when an engine rotational speed changing operation member is operated to a maximum extent, and shows, in a listed manner, the calculated results in a liquid crystal display part of a display device. The present invention can inform an operator of the maximum rotational speed of PTO rotary power that is output from the PTO shaft for each speed-changing stage in the PTO transmission without performing a speed changing operation on the PTO transmission.

摘要:
A control apparatus is applied to a hybrid vehicle (1A). The hybrid vehicle (1A) includes an MG (3) which is connected with an input shaft (11) of a manual transmission (10) via a first clutch (20) that is operated by a press operation to a clutch pedal (CP) and an internal combustion engine (2) which is connected with the MG (3) via a second clutch (21). The hybrid vehicle (1A) is allowed to execute an EV traveling mode where: the internal combustion engine (2) is stopped; the internal combustion engine (2) and drive wheels (5) are separated by the second clutch (21); and the drive wheels are driven by the MG (3). In the control apparatus, when the EV traveling mode is executed, a required torque (T1) is obtained based on an accelerator opening degree, and a required transmission torque (T2) is obtained based on an operation amount to the clutch pedal. And, when a smaller one of the required torque (T1) and the required transmission torque (T2) is greater than a determination value, the internal combustion engine (2) is started.
