  • Patent number: 10843518
    Abstract: A fragile portion is provided at a portion of a suspension arm which is positioned near a vehicle-body attachment portion. The fragile portion is configured such that when a load which is greater than a specified magnitude is inputted to a front wheel from a vehicle forward side, the suspension arm is bent at the fragile portion, whereby the front wheel is rotated rearwardly around the fragile portion.

  • Patent number: 10773752
    Abstract: A reinforcing member is provided inside a closed cross section of a front side frame at a position, in a vehicle longitudinal direction, which corresponds to a forming position of a bead. The reinforcing member extends between an outward side wall portion and an inward side wall portion of the front side frame. The reinforcing member is joined to the outward side wall portion and the inward side wall portion of the front side frame. A joint length, in the vehicle longitudinal direction, of the reinforcing member and the inward side wall portion is set to be longer than that of the reinforcing member and the outward side wall portion.

  • Patent number: 10703313
    Abstract: A vehicle body structure includes a frame extending in a vehicle longitudinal direction outside a power train in a vehicle width direction, the power train being mounted on a front portion of a vehicle. The vehicle body structure further includes a load receiving portion expanding outward in the vehicle width direction from a front end of the frame and configured to receive impact load acting upon front collision of the vehicle outside the frame in the vehicle width direction, a cutout portion provided at the front end of the frame and cut out rearwardly from the front end of the frame to leave two side portions, and a connection member connecting the side portions of the cutout portion in the vehicle width direction.

  • Patent number: 10696179
    Abstract: An electrically powered vehicle includes a power supply device, a first outlet, a second outlet, and an electronic control unit. The first outlet configured to be connected to an external equipment that is not constituent equipment of the electrically powered vehicle. The second outlet is configured to be connected to an external equipment that is not constituent equipment of the electrically powered vehicle. While first power feed and second power feed are being executed simultaneously, in a case where first power feed electric power exceeds a first threshold or in a case where total electric power of the first power feed and the second power feed exceeds a second threshold, the electronic control unit is configured to temporarily stop the second power feed and continue the first power feed.

  • Patent number: 10676134
    Abstract: A dash cross member which extends in a vehicle width direction is provided at a dash panel. A hinge-pillar reinforcing member which rigidly connects a hinge pillar to a side sill is provided at a lower end portion of the hinge pillar. A load-transmission portion (a dash reinforcement) to transmit a load which is inputted to the hinge-pillar reinforcing member in an inward direction of the vehicle width direction to the dash cross member is provided at the dash panel.

  • Patent number: 10647361
    Abstract: A frame (extension frame) extending in a vehicle longitudinal direction on an outward side, in a vehicle width direction, of a powertrain mounted at a front portion of a vehicle includes front-side and rear-side high strength portions which are spaced apart, in the vehicle longitudinal direction, from each other and a low strength portion which is positioned, in the vehicle longitudinal direction, between the both high strength portions. The low strength portion has a lower bending strength than each of the both high strength portions. A specified portion which is a part of the low strength portion is positioned on the outward side, in the vehicle width direction, of and in front of a part of the powertrain (oil pan) which is located at the same level as the specified portion of the frame.

  • Patent number: 10384543
    Abstract: An electrically powered vehicle includes a power supply device, a first outlet configured to be connectable to external equipment that is not constituent equipment of a vehicle, a second outlet configured to be connectable to external equipment that is not constituent equipment of the vehicle, a display device configured to display a first image representing that first power feed is in progress and a second image representing that second power feed is in progress, and an electronic control unit configured to control an image to be displayed on the display device. In a case where the first power feed and the second power feed are being executed, the electronic control unit is configured to perform control such that a display form of the first image is more noticeable than a display form of the second image.
