A touch operation detection device (100) includes a controller (13). The controller (13) recognizes a direction of a swipe operation performed on a touch sensor (11) based on a touch point of a finger of an operator on the touch sensor (11), the touch sensor (11) being arranged in a range in which the touch sensor (11) is operable with the finger of the operator in a state where an operation device (2) is gripped by the operator. The controller (13) determines the direction of the swipe operation based on a plurality of regions (R1 to R8) radially divided from a central portion of the touch sensor. A size of at least one of the plurality of regions (R1 to R8) is different from sizes of the other regions.

An all-solid-state battery (1A) includes a power generating element (30) stacked with a positive electrode layer (40), a solid electrolyte layer (60), and a negative electrode layer (50) in this order along a Z-direction, a positive electrode current collector (10) in contact with the positive electrode layer (40), a negative electrode current collector (20) in contact with the negative electrode layer (50). The positive electrode layer (40) includes a side surface (40b) in contact with the solid electrolyte layer (60). The side surface (40b) inclines to approach a center of the positive electrode layer (40) as approaching from the positive electrode current collector (10) to the negative electrode current collector (20). The all-solid-state battery (1A) further includes a non-Li ion conductivity covering portion (70) that is disposed in the positive electrode current collector (10) and covers the side surface (40b), and the covering portion (70) has a thickness (T<3>) in the Z-direction thinner than a thickness (T<1>) of the power generating element (30) in the Z-direction.

An electric vehicle in which an electric unit including an electric motor and a case housing the electric motor is mounted and fixed to a vehicle body at a plurality of fixing points is provided.. In the electric vehicle, the fixing points include at least a first fixing point set on a side member positioned on a side surface side of the electric vehicle relative to the electric unit, and a second fixing point set on a suspension member positioned on a rear side of the electric vehicle relative to the electric unit. The case is provided with a reinforcing portion having enhanced rigidity at a part on a rear side of the electric vehicle relative to a straight line connecting the first fixing point and the second fixing point in a top view of the electric vehicle.

A harness attachment structure in a vehicle is provided. The vehicle includes a drive unit configured to drive the vehicle and a battery unit configured to supply power to the drive unit via a harness. The drive unit is disposed on a vehicle rear side relative to the battery unit and includes a drive motor configured to drive a driving wheel and an inverter unit configured to convert power of the battery unit and supply the converted power to the drive motor. The harness includes one end configured as the first connection portion that is connected to the battery unit toward a vehicle front side at a rear portion of the battery unit, and the other end configured as the second connection portion that is connected to the inverter unit in a vehicle width direction at a side portion of the inverter unit. The harness is routed to curve at least in the vehicle width direction between the first connection portion and the second connection portion.

Provided is an electric vehicle control method that selectively executes either a first power limit mode or a second power limit mode as a battery thermal protection mode in which a vehicle driving force is limited based on an upper limit battery power. In the first power limit mode, the upper limit battery power is calculated using a basic upper limit battery power function. In particular, the basic upper limit battery power function is determined to decrease in accordance with an increase in the battery temperature in a temperature region equal to or higher than a basic battery protection temperature. In the second power limit mode, the upper limit battery power is calculated using a corrected upper limit battery power function. In particular, the corrected upper limit battery power function is determined to decrease at a change rate lower than that of the basic upper limit battery power function in accordance with the increase in the battery temperature in a temperature region equal to or higher than a corrected battery protection temperature lower than the basic battery protection temperature.

A resin part of the present invention includes a photocatalytic coating on a surface of a resin base body.The photocatalytic coating has a sea-island structure in which island parts containing anatase type titanium dioxide particles are dispersed within a sea part containing a metal material, so that it is possible to provide a resin part including a photocatalytic coating that achieves both high photocatalytic effect and prevention of deterioration of the resin base body.
