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 power supply system includes a plurality of electrical storage devices, a distributor configured to distribute electric power between the plurality of electrical storage devices in a desired distribution mode, and an electronic control unit. The electronic control unit configured to (i) set the desired distribution mode based on at least one of a magnitude relation between first rates of change in dischargeable power of the corresponding electrical storage device to a charge state value indicating a remaining level of charge of the corresponding electrical storage device, or a magnitude relation between second rates of change in chargeable power of the corresponding electrical storage device to the charge state value, and (ii) control the distributor such that electric power is distributed in the set distribution mode.

Power supply system

A control system for a hybrid vehicle configured to reduce frequency of establishing an engine braking force is provided. The control system is configured to operate a first motor as a motor to increase torque of an output member while halting the output shaft of the engine by a brake, and to increase the deceleration torque of the second motor, if a state of charge of the battery is higher than a predetermined threshold level when deceleration of the hybrid vehicle is demanded.

Control system for hybrid vehicle

A control system for hybrid vehicles that prevents an occurrence of shock resulting from manually shifting an operating mode is provided. The control system is configured to switch an operating mode between HV mode in which the vehicle is powered mainly by the engine and EV mode in which the vehicle is powered mainly by said motor in response to a manual switching operation. The control system delays a startup of the engine until satisfaction of a predetermined running condition, if the manual switching operation is executed to shift from the EV mode to the HV mode under a condition that the running condition falls within a region where both of the HV mode and the EV mode are selectable.

A hybrid vehicle includes: an electricity storage device configured to output electric power to and receives electric power from a vehicle-driving electric motor and to be charged with electricity generated by using output of an engine; an external charging portion that charges the electricity storage device with electric power supplied from outside the vehicle; and a control device that controls switching between the traveling of the vehicle which does not use the engine but uses the electric motor and the traveling which uses the engine. The control device restrains the traveling that uses the engine, during a period until charging is newly executed by the external charging portion, if degree of execution of the traveling that uses the engine following previous execution of the external charging is greater than a predetermined degree.

Hybrid vehicle

A hybrid vehicle includes an engine including a purification device, a motor, a battery, a navigation system, and a controller. The controller is configured to set a predetermined section, which is an initial section of a hybrid traveling priority section in a travel plan, for a warm-up section for warming up the purification device. The controller is configured to reset the travel plan by changing any one of an electric traveling priority sections before the predetermined section to the hybrid traveling priority section when a traveling load of the predetermined section is higher than a predetermined load corresponding to an output limit of the battery. The controller is configured to reset the section changed to the hybrid traveling priority section for the warm-up section for warming up the purification device.

A hybrid vehicle includes: an engine; a motor; a battery; a navigation system; and a controller configured to carry out navigation coordination traveling, the controller being configured to stop the navigation coordination traveling when a state of charge of the battery becomes lower than or equal to a first switching threshold, the controller being configured to resume the navigation coordination traveling when the state of charge of the battery becomes higher than or equal to a second switching threshold higher than the first switching threshold, the controller being configured to set a first predetermined state of charge for the first switching threshold when there is no regenerative travel section, and the controller being configured to set a second predetermined state of charge lower than the first predetermined state of charge when there is the regenerative travel section.

A vehicle includes: an engine driven with gasoline; a lid member opening/closing an opening of an accommodation room that accommodates a nozzle receiving unit when gasoline is supplied; a rotating electric machine driven on electric power; a charging/power feeding unit receiving electric power; a lid member opening/closing an opening of an accommodation room accommodating a charging/power feeding unit; and an open/close control mechanism setting the other of the lid member and the lid member in the closed position when one of the lid member and the lid member is set in the open position.
