A fuel cell system includes a fuel cell including a plurality of stacked cells, a fuel gas supply unit configured to supply fuel gas to a supply port of the fuel cell and return the fuel gas exhausted through an exhaust port of the fuel cell, and a controller configured to control an operation of the fuel gas supply unit. The controller is configured to execute a drain process for draining residual water accumulated in the fuel cell through the exhaust port. In the drain process, a first process in which the fuel gas is supplied to the fuel cell until a pressure in the fuel cell reaches a predetermined threshold pressure and a second process in which the pressure in the fuel cell is reduced after the first process are repeatedly executed.

Fuel cell system

A fuel cell system includes a fuel cell stack, a fuel gas supply path, an injector, an ejector, a circulation path, a pressure difference detection unit that detects a pressure difference between an ejector inlet port pressure and an ejector outlet port pressure, and a control device. The control device calculates a required circulation flow rate that is required for a fuel off gas supplied from the fuel cell stack to the ejector, based on a required load for the fuel cell stack, calculates an estimated circulation flow rate that is an estimated flow rate of the fuel off gas supplied from the fuel cell stack to the ejector, based on the required load and the pressure difference, and increases the flow rate of a fuel gas supplied from the injector to the fuel cell stack when the estimated circulation flow rate is lower than the required circulation flow rate.

A fuel cell system includes a fuel cell stack, a fuel gas supply path, an injector, an ejector, a circulation path, an outlet port pressure detection unit, and a control device. The control device stops driving the injector when an ejector outlet port pressure is equal to or more than a required upper limit value with the injector driven, and drives the injector when the ejector outlet port pressure is equal to or less than a required lower limit value with the injector stopped. The control device reduces the required upper limit value stepwise and reduces the required lower limit value stepwise in a range defined by a first target upper limit value and a second target upper limit value when a required load is varied from a first required load to a second required load and a load reduction amount is more than a first predetermined load.

A fuel cell system includes a fuel cell, a fuel gas supply channel, a regulator, an injector, and a controller. The controller drives the regulator in conjunction with the injector. The controller compares a fuel gas flow amount necessary for the fuel cell to generate electricity with a predetermined fuel gas flow amount, selects the fuel gas flow amount that is larger, and issues commands to the regulator and the injector. The predetermined fuel gas flow amount is set to be larger than the fuel gas flow amount necessary for the fuel cell to generate the electricity when a generated current or output of the fuel cell is smaller than a predetermined threshold value.

Provided is a fuel cell system that can effectively suppress clogging of a pipe due to freezing of water in a fuel gas supply system thereof without the need for halting the operation of the fuel cells, and thus is highly reliable. When possible freezing of water is detected or presumed to be present downstream of an injector, the amount of a fuel gas to be supplied from a circulation pump that is disposed in a circulation channel is relatively increased compared to the amount of the fuel gas to be supplied from the injector.

A control unit of a fuel cell system includes a valve control unit configured such that, when it is determined that an exhaust valve is stuck open in a quick warming-up operation, the valve control unit sets at least one of an operable opening area which is an opening area capable of being changed by control and a rate of opening change which is an opening changeable frequency at which an opening is changeable per unit time, for at least one of a pressure adjusting valve and a flow division valve, such that a flow rate of a cathode gas supplied to a fuel cell is in an allowable range of a requested supply flow rate required for the quick warming-up operation.

Display control systems, methods, and programs obtain an indicated location indicated by a pointer, based on an output from a pointing device, and display, on a display, a user interface screen that displays icons at predetermined locations and displays the pointer indicating the indicated location. The systems methods, and programs draw, when the indicated location is present in a draw-in region including one of the icons, the indicated location into the icon. The systems methods, and programs set, when a first icon and a second icon for performing operations related to a same function are arranged side by side on the display, a first draw-in region including the first icon and a second draw-in region including the second icon such that the first draw-in region and the second draw-in region are present in a region between the first icon and the second icon and adjacent to each other.

Display control system, method, and program

A vehicular input device includes a position detection unit, a display unit, and an ECU. The ECU is configured to set, based on a movement amount of a position of an operative input, a determination threshold of the movement amount of the operative input used in determination of movement to a next object from a current object to be smaller than a determination threshold of the movement amount of the operative input used in determination of movement to a next second object from the next object. The ECU is configured to display a selection image that indicates selected objects on the display unit on the current object.

Vehicular input device and method of controlling vehicular input device

A vehicular input device includes a position detection unit that is disposed within a vehicle cabin, has an operative input surface on which a user performs an operative input, and detects a position of the operative input performed on the operative input surface; a display unit that is disposed within the vehicle cabin; and an ECU configured to display a selection image in an overlaid manner on an object within the display unit in a position corresponding to the position of the detected operative input when the position detection unit detects the operative input. The selection image is used to select the object within the display unit. The ECU highlights the selection image displayed on the display unit when the position of the operative input is detected by the position detection unit, further than when the position of the operative input is not detected by the position detection unit.

A vehicular display apparatus includes a display section, a pointing device, and a display control section. The display control section is configured to display an operation screen on the display section. The display control section is configured to generate an image that includes one of an object and an object group across a specified area on the operation screen, and execute processing of setting a part of the one of the object and the object group in a different display mode from the other part of the one of the object and the object group when the operation finger is recognized by a recognition section.

Vehicular display apparatus

An input device for a vehicle includes a determiner to calculate a correspondence position corresponding to the position of an input operation in a display unit, and to determine a content of the input operation; and a controller to control displaying an object depending on a determination result of the determiner, and to overlappingly display a selection image to select an object at the correspondence position. When the selection image is overlappingly displayed with an object whose selection items are consecutively replaced and displayed by the input operation, if the position is moved without a preceding press or long press operation, the selection item to be displayed is changed by a predetermined count in the moved direction of the position; or if the position is moved after a preceding press or long press operation, the selection item is consecutively changed proportionally to the moved amount of the position.
