A lower kick section sloping with a downward gradient on progression toward a vehicle rear side is formed at a rear section of each of the front side frames. The left and right front side members extend along the vehicle front-rear direction at a vehicle upper side of the left and right front side frames, are supported by the left and right front side frames, and configure part of a vehicle body. An upper kick section sloping with a downward gradient on progression toward the vehicle rear side is formed at a rear section of each of the front side members.

Vehicle front section structure

Instrument panel side parts are provided integrally with an instrument panel main body part. Vehicle-mounted components are housed in the instrument panel side parts. Thus, even in a vehicle in which an engine compartment is not provided on a vehicle front side in a vehicle cabin it is possible to ensure a housing space for these vehicle mounting parts. Further, the instrument panel side parts are provided integrally with the instrument panel main body part. Thus, compared to a case in which the instrument panel side parts are separated from the instrument panel main body part, a space around the driver's seat can be expanded by the reduced amount of dead space, and the comfortability of the driver can be ensured.

Front sections of the left and right front side members and the corresponding left and right deformation portions are connected by left and right coupling members. The left and right coupling members are configured so as to more readily undergo plastic deformation under collision load at a time of head-on collision than the left and right front side members.

A vehicle front portion structure includes: a dash panel separating a power unit compartment provided at a lower portion of a vehicle front portion from a cabin; a partition wall having a lower end portion secured to a vehicle rear end portion of the dash panel and extending in a vehicle upward direction to divide the cabin into a front portion and a rear portion; a front portion vehicle seat disposed on the dash panel; a seat support member supporting the front portion vehicle seat from a vehicle lower side and having a front end portion secured to the dash panel and a rear end portion secured to the partition wall; and an autonomous driving unit, at least part of the autonomous driving unit being disposed in an area surrounded by the dash panel, the partition wall, and the seat support member.

Vehicle front portion structure

A compressor installation structure for a vehicle has: a battery that is disposed at a vehicle lower side of a floor portion of a vehicle cabin; a power unit that is disposed at one side in a vehicle front-rear direction with respect to the battery; and a compressor that is configured to be driven by electric power supplied thereto from the battery, and that is disposed at one side in the vehicle front-rear direction with respect to the battery, and that is disposed at another side in a vehicle front-rear direction with respect to the power unit.

Compressor installation structure for vehicle

The bottom bracket supports the bottom wall of the housing of the electronic device unit. The rear end of the support rod is in contact with the front wall of the housing. The support rod extends from the front wall of the housing to the front of the vehicle. A front bracket supports the front portion of the support rod. The front bracket has a flange and a hook. The flange is secured to the vehicle body in an area adjacent to the support rod in the width direction. The hook is connected to the flange at one end. The hook extends from the vehicle-width side of the support rod across the top surface of the support rod to the opposite side of the vehicle-width side. Furthermore, the hook is free-ended at the other end.

Support structure for onboard electronic device assembly

A vehicle lower part structure includes: center rail portions disposed at a central part in a front-rear direction of the vehicle; front rail portions disposed forward of the center rail portions in the front-rear direction of the vehicle; rear rail portions disposed rearward of the center rail portions in the front-rear direction of the vehicle; front connecting rail portions connecting the center rail portions and the front rail portions in the front-rear direction of the vehicle; rear connecting rail portions connecting the center rail portions and the rear rail portions in the front-rear direction of the vehicle; first mount portions supporting a vehicle body constituting a cabin; and second mount portions supporting the vehicle body.

Vehicle lower part structure

An electric vehicle cooling system, including: a first radiator installed at a vehicle and configured to cool a power unit driven by electrical power; and a second radiator installed at the vehicle, disposed at least at one side in a vehicle width direction, or another side in the vehicle width direction, of the first radiator so as not to overlap with the first radiator as viewed along a vehicle front-rear direction, and configured to cool an autonomous driving control device configured to control autonomous driving of the vehicle.
