  • Publication number: 20220410733
    Abstract: A power transfer system includes: a compact mobility; a ground unit disposed on a second lane which is a driving lane for the compact mobility, the ground unit being capable of wireless power transfer; and a controller that controls the ground unit. The compact mobility has an amount of electric power that can be stored less than a predetermined amount, and travels at a speed dependent on electric power wirelessly received from the ground unit. When a pedestrian is sensed in the second lane, the controller forces the compact mobility to decelerate by reducing transmission power from the ground unit to the compact mobility, as compared to when the pedestrian is not sensed in the second lane.

    Abstract: A vehicle is capable of receiving electric power supplied from a charger and capable of receiving electric power supplied from a charging mat. The charging mat is movable and capable of wireless power transfer. A method for providing a vehicle charging service includes a first step and a second step. The first step is giving, by a server, an instruction for installing the charging mat on a lane at which charging congestion is detected or predicted to occur, the charging congestion being traffic congestion for charging the electric power supplied from the charger. The second step is transmitting the electric power from the charging mat when the vehicle is detected above the charging mat installed on the lane in accordance with the instruction, and transmitting no electric power from the charging mat when the vehicle is not detected above the charging mat.

  • Patent number: 11060472
    Abstract: There is provided an engine working machine capable of suppressing functional disorder of an exhaust catalyst and decline of engine performance. If, during input of a dummy load to an engine, fuel supply volume of a fuel supply device reaches a predetermined dummy load cutoff determination value as a result of elevation of a total load for an engine including the dummy load and a work load, then an electronic control device switches a load switching device to cut off the dummy load; and if, during input of the work load without including the dummy load to the engine, the fuel supply volume of the fuel supply device reaches a predetermined dummy load re-input determination value as a result of decline of the work load, then the electronic control device switches the load switching device to re-input the dummy load.
