  • Publication number: 20210300363
    Abstract: The present invention provides a saddle ride type vehicle including a sensing unit configured to sense a four-wheel vehicle that is present in front of a self-vehicle and is traveling in a travel lane of the self-vehicle, and a control unit configured to, in a case where the four-wheel vehicle is sensed by the sensing unit, perform follow-travel control for causing traveling of the self-vehicle to follow traveling of the four-wheel vehicle, wherein the sensing unit senses a vehicle width of the four-wheel vehicle, and the control unit, in the follow-travel control, controls a travel position in a vehicle width direction of the self-vehicle so that at least a portion of the self-vehicle falls within a region within the vehicle width of the four-wheel vehicle.

  • Publication number: 20210284190
    Abstract: A straddle type vehicle includes a setting unit configured to set a warning line along a boundary between a traveling lane of a self-vehicle and an oncoming lane, a warning unit configured to issue a warning if the self-vehicle has crossed the warning line, a detection unit configured to detect a difficult-to-travel region in the traveling lane, and a determination unit configured to determine whether it is difficult or possible for the self-vehicle to pass between the boundary and the difficult-to-travel region. If it is determined by the determination unit that it is difficult for the self-vehicle to pass, the setting unit changes a position of the warning line to a position shifted from the boundary toward the oncoming lane side.

  • Patent number: 10800489
    Abstract: A rider operates a driving source switching lever to switch an operation mode to a normal traveling mode or an auxiliary moving mode. During the normal traveling mode, a motorcycle travels by a driving force generated by an engine. During the auxiliary moving mode, the motorcycle moves at a low speed by a driving force generated by a vehicle driving motor. When the rider operates a forward-backward movement operator during the auxiliary moving mode to put the forward-backward movement operator in a forward movement instruction state, the vehicle driving motor is controlled such that the motorcycle moves forward. When the rider operates the forward-backward movement operator during the auxiliary moving mode to put the forward-backward movement operator in a backward movement instruction state, the vehicle driving motor is controlled such that the motorcycle moves backward.

  • Patent number: 10457288
    Abstract: A motorcycle includes an engine that generates a driving force during a normal traveling mode, and a vehicle driving motor that generates a driving force for moving a vehicle main body forward and backward during an auxiliary moving mode. A traveling speed of the vehicle main body is detected by a speed sensor, and the detected traveling speed is presented to the rider by a speedometer. A rotation speed of the vehicle driving motor or a rotation speed of a gear rotated by the vehicle driving motor is detected by a rotation speed sensor as a physical quantity that changes depending on a moving speed of the vehicle main body during the auxiliary moving mode. The vehicle driving motor is controlled based on the detected rotation speed such that the moving speed of the vehicle main body is close to or coincides with a target speed.

  • Patent number: 8920588
    Abstract: A substrate may include a plurality of wirings arranged side by side to extend in a predetermined direction, and a protective insulating layer formed between adjoining pixels and formed as a rib protruding from the substrate. An emissive layer formation method for transferring, to the substrate, an emissive layer provided on a transfer element may include pressing the emissive layer on the transfer element onto the protective insulating layer and affixing it through pressure to a top surface of the rib. Thereby the emissive layer transferred to the substrate is confined to an area which is surrounded by the rib of the protective insulating layer, the substrate and the transfer element, and diffusion of the emissive layer is controlled by the area, thereby transferring the emissive layer in the area.
