Abstract: A traffic signal detection device includes a narrow-angle camera, a wide-angle camera having an angle of view wider than the narrow-angle camera, and a traffic signal detector configured to detect a traffic signal from at least any of a narrow-angle image captured by the narrow-angle camera and a wide-angle image captured by the wide-angle camera. The traffic signal detector selects, as a detection result, any of a traffic signal detected from the narrow-angle image and a traffic signal detected from the wide-angle image, on the basis of a deceleration start region in which a vehicle should start deceleration, the deceleration start region calculated from a position of a traffic signal with respect to the vehicle and a speed of the vehicle in order to stop the vehicle at a stop position with respect to the traffic signal.

Abstract: A cell module for a solid oxide fuel cell includes a cell substrate (1) having gas permeability, one electrode (2) among a fuel electrode and an air electrode formed on the cell substrate, a solid electrolyte (3) formed on the one electrode, and the other electrode (4) formed on the solid electrolyte, wherein in the case of counter-flow of the fuel gas and the oxidant gas flow, the gas permeability of a central portion (1b) of the cell substrate in the gas flow direction is lower than the gas permeability of an inlet portion (1a) and an outlet portion (1c) of the cell substrate.
Abstract: An object of a control method to control a direct injection internal combustion engine that directly injects fuel in a cylinder is to reduce an increase in PN caused by attachment of the fuel to a fuel injection valve distal end. The control method cools the fuel before a fuel temperature when the fuel passes through an injection hole on a fuel injection valve reaches a temperature at which an amount of attached fuel to the fuel injection valve distal end increases.
Abstract: A vehicular display device configured to display a guide route to a destination of a host vehicle includes a navigation device configured to calculate the guide route, a display controller configured to draw an arrow having a shaft with an arrowhead at one end of the shaft, as a guide figure for guidance along the guide route calculated by the navigation device, such that the arrow is shaped as a three-dimensional object in which one surface of the arrow is a continuous flat surface from the shaft to the arrowhead and the other surface of the arrow includes a first portion with a first width having a first height, and a second portion with a second width smaller than the first width and having a second height smaller than the first height, and a display configured to display an image drawn by the display controller in a display area.
Abstract: A power supply system that is mountable on a vehicle has a lead-acid storage battery connected to an electrical load, a lithium-ion storage battery having different charge and discharge characteristics form the lead-acid storage battery, and connected in parallel with the lead-acid storage battery with respect to the electrical load, a power generator configured to charge the lead-acid storage battery and the lithium-ion storage battery, and a controller configured to drive the power generator based on a relationship between a discharge current of the lead-acid storage battery and a discharge current of the lithium-ion storage battery.
Abstract: A wireless power supply system of the present invention performs wireless power supply between a power transmission coil installed at a parking space and a power reception coil mounted on a vehicle, transmits judging power for judging a parking position from the power transmission coil to the power reception coil in an operation of parking the vehicle in the parking space, and sets an excitation frequency of the judging power to a frequency lower than an in-phase resonance point or higher than an anti-phase resonance point.
Abstract: A parking assist method for assisting parking of a subject vehicle uses a parking assist apparatus comprising a controller that guides the subject vehicle to a parking space and a display that displays the parking space. The parking assist method comprises: specifying an available parking space into which the subject vehicle can be parked; displaying the available parking space on the display; when the available parking space is in a parking-unavailable state that represents a state in which the subject vehicle cannot be parked into the available parking space, determining whether or not the parking-unavailable state is canceled; and when the parking-unavailable state is canceled before a first time passes, maintaining a display form of the available parking space on the display.
Abstract: A cell structure for a fuel cell stack that is formed by stacking unit cells C each including a membrane electrode assembly 1 and a pair of separators 2 holding the membrane electrode assembly 1 therebetween. The membrane electrode assembly 1 includes a frame 3 in the periphery having such a size as to extend outward over the edges of the separators 2. Communication holes 21, 22 in communication with the front and back sides are formed in the frame 3 in an area from a sealing part 11 between frames 3 adjacent in the cell stacking direction to a sealing parts 12 between the membrane electrode assembly 1 and the separators 2. The air in a space Q formed between the inner and outer sealing parts 11, 12 is allowed to be released to the outside through the communication holes 21, 22, and a breakage of the adhesive of the sealing parts 11, 12 is thereby prevented.
Abstract: A ground-side coil unit is provided with: a magnetic material plate disposed adjacent to a power transmission coil that transmits electric power to a power reception coil in a wireless manner; and a first filter coil disposed facing the power transmission coil with the magnetic material plate interposed therebetween. The first filter coil is disposed in a position where a magnetic flux generated by the first filter coil cancels out a magnetic flux generated by the power transmission coil in the magnetic material plate.
Abstract: A control device is provided for an electric vehicle that generates a braking force corresponding to an opening degree of an accelerator pedal to decelerate the electric vehicle. The control device for the electric vehicle includes a motor configured to generate a driving force or a regenerative braking force of the electric vehicle, a friction braking unit configured to generate a friction braking force, and a controller configured to control at least one of the motor and the friction braking unit corresponding to the opening degree of the accelerator pedal. The controller determines whether all of regenerative electric power generated by the motor is consumed in the electric vehicle when the motor is caused to perform a regenerative braking. The controller causes the motor to perform the regenerative braking when the regenerative electric power is determined to be consumed in the electric vehicle.
