  • Patent number: 11745595
    Abstract: A plurality of control maps respectively corresponding to a plurality of lever operation amounts are stored in a storage device. Each control map defines a driving force to be output from an electric motor such that the driving force corresponds to an accelerator operation amount and a vehicle speed. A control device uses a control map corresponding to an actual lever operation amount among the plurality of control maps and thereby calculates the driving force to be output from the electric motor based on an actual accelerator operation amount and an actual vehicle speed from the control map. This vehicle can alleviate discomfort caused when a driver accustomed to an engine vehicle operates an electric vehicle.

  • Patent number: 11724894
    Abstract: A judgment process of judging whether or not the movable linear module is located in the facing range is performed before the slider transfer operation of moving the slider from the fixed linear module to the movable linear module located in the facing range is performed. As a result, unless the movable linear module is judged to be located in the facing range, the slider transfer operation is performed after a preparation operation of moving the movable linear module into the facing range is performed. Therefore, the slider can be properly moved from the fixed linear module to the movable linear module.

  • Patent number: 11702300
    Abstract: The transfer operation of moving the slider between one fixed linear module and the movable linear module while locating the movable linear module in the facing range facing toward the one fixed linear module, out of the plurality of linear modules arranged in parallel, is performed. At this time, a judgement process of judging whether or not the coordinate axis of the one fixed linear module and the coordinate axis of the movable linear module are continuous is performed. If it is judged that the coordinate axes are not continuous, the transfer operation is performed while the speed control is executed for the slider. Thus, it is possible to suppress the occurrence of a situation where the transfer operation of moving the slider between the movable linear modules cannot be performed due to the discontinuity of the coordinate axes respectively set for the movable linear modules.
