A tractor includes a working motor, a work machine including a roller configured to rotate by an output from the working motor, a support mechanism configured to support the work machine such that a working posture and a retracting posture are achievable, and a control device. The control device executes: an adherence amount acquisition process of acquiring an estimated adherence amount as an estimated value for the amount of mud attached to the roller; and a mud removal process of, when the estimated adherence amount is equal to or more than a determination adherence amount, removing the mud from the roller by driving the working motor in a state where the work machine takes the retracting posture.

Tractor

Provided is a control device of a working vehicle including a prime mover and a driving mechanism that drives an implement based on power of the prime mover, wherein the control device is configured to obtain a steering angle of the working vehicle, and detect switching between tasks performed by the working vehicle in a farm field, when the steering angle is equal to or greater than a predetermined angle indicating the switching between tasks.

Control device of working vehicle

A hybrid vehicle includes: an engine; a motor; a drive system battery connected to a drive system power line; an auxiliary system battery connected to an auxiliary system power line; a bidirectional power converter configured to step down power on the drive system power line to supply the stepped-down power to the auxiliary system power line, and configured to boost power on the auxiliary system power line to supply the boosted power to the drive system power line; and a control device. The control device is configured to, upon a cold start in which the engine is started, control the engine, the motor, and the bidirectional power converter to cause the motor to crank the engine while causing the bidirectional power converter to boost the power on the auxiliary system power line to supply the boosted power to the drive system power line.

Hybrid vehicle and method for controlling hybrid vehicle

In a hybrid vehicle configured such that a sun gear, a carrier and a ring gear of a planetary gear are respectively connected with a rotating shaft of a motor MG, a crankshaft of an engine and a driveshaft and that a motor MGis connected with the driveshaft, when a required braking force that is to be output to the driveshaft is equal to or less than a reference value Tref in an accelerator-off state, the braking force by engine braking is output to the driveshaft by motoring of the engine by the motor MG. When the required braking force becomes greater than the reference value Tref, on the other hand, the power output from the engine by load operation of the engine in a reverse rotating direction is output as the braking force to the driveshaft.
