  • Publication number: 20200109682
    Abstract: In a first region on a low load side of an operation region of a direct fuel injection engine, homogenous combustion is performed, while, in a second region of the operation region on a load side higher than the first region, stratified combustion is performed. In the stratified combustion, a fuel is dispersed in a cylinder by a first injection operation and a fuel is unevenly distributed in a vicinity of the ignition plug by a second injection operation. Shift control by the stratified combustion is executed at a time of shifting when an operation state of the engine has shifted from the first region to the second region, and in the shift control, a fuel in an amount larger than a target amount of the second injection operation in the second region is injected by the second injection operation and then, an injection amount of the second injection operation is decreased toward the target amount.

  • Patent number: 10612651
    Abstract: In a vehicle equipped with a torque converter 4 having a lock-up clutch (3), learning control for obtaining a learning value (L_n) on the basis of meet-point information, with which the lock-up clutch (3) initiates torque transmission, is carried out. When the lock-up clutch (3) experiences a transition to an engaged state during travel, a meet-point learning control unit (12c) calculates an LU transmission torque estimate on the basis of the difference between the engine torque (engine torque signal value Te) and the torque converter transmission torque (?·Ne2). Excess clutch capacity is detected when the LU transmission torque estimate is greater than an excess capacity determination transmission torque threshold within a prescribed amount of time after an initial pressure (P_n) based on the learning value (L_n) is instructed. When excess clutch capacity is detected, a learning value correction that reduces the learning value (L_n) is carried out.

  • Patent number: 10585435
    Abstract: The travel route calculation device includes a travel route calculation unit configured to calculate a travel route for a subject vehicle to arrive at a destination, a feature detection unit configured to detect a feature, and a distance measurement unit configured to measure a distance from the subject vehicle to the feature as a necessary recognition distance. The necessary recognition distance is necessary for the subject vehicle to recognize the feature when deciding an action of the subject vehicle. The travel route calculation device further includes a determination unit configured to determine difficulty in recognizing the feature, on the basis of a detection range of the feature detection unit and the necessary recognition distance. The travel route calculation unit calculates the travel route while avoiding a location at which recognition of the feature is determined to be difficult by the determination unit.

    Abstract: A method for molding a composite material and a device for molding a composite material are provided which are able to suppress the occurrence of voids in a composite material and improve the mechanical characteristics and appearance quality of the composite material. In the method for molding a composite material (10), a seal region (270) including a cavity (250) in which a reinforcing base material (11) is disposed and an outer peripheral region (260) that communicates with an outer periphery of the cavity is air-tightly sealed by means of a first sealing member (310). Then, an operation of suctioning a gas from the outer peripheral region to evacuate the gas in the seal region is started, and a resin (12) is injected into a part of the cavity. Next, a mold (200) is clamped to provide a liquid-tight seal between the cavity and the outer peripheral region by means of a second sealing member (320) while pressing the resin to fill the cavity with the resin.

  • Patent number: 10580296
    Abstract: Methods, apparatuses, systems, and non-transitory computer readable storage media for generating risk indicators are described. The disclosed technology includes determining a vehicle route of a vehicle and external object routes of external objects. The vehicle route is determined using vehicle route data including a vehicle location and a vehicle destination. The external object routes are determined using external object route data including external object locations and external object destinations. Based on a comparison of the vehicle route data and the external object route data, external object routes that satisfy a proximity criterion are determined. Risk data for the vehicle is generated based on a vehicle state of the vehicle and external object states of the external objects corresponding to the external object routes that satisfy the proximity criterion. In response to determining that the risk data satisfies a risk criterion, at least one risk indicator is generated.

  • Patent number: 10581096
    Abstract: A fuel cell system calculates a target value of a flow rate of cathode gas to be supplied to a fuel cell stack according to a request of the fuel cell stack, controls a flow rate of the cathode gas to be supplied by the compressor according to an operating state of the fuel cell system, controls a bypass valve based on a target fuel cell supply flow rate so that the flow rate of the cathode gas to be supplied from the compressor to the fuel cell stack reaches the target fuel cell supply flow rate, and limits the flow rate of the cathode gas to be supplied by the compressor when the bypass valve has a predetermined opening and the flow rate of the cathode gas to be supplied to the fuel cell stack is not smaller than the target fuel cell supply flow rate.

    Abstract: A gear pair includes a first gear and a second gear that are engaged and paired with each other, wherein the arithmetic average roughness Ra of the tooth surface of the first gear is less than 0.10, and the arithmetic average roughness Ra of the tooth surface of the second gear is equal to or greater than 0.15. An improvement of the transmission efficiency is achieved due to the improved composite roughness of the gear pair. Accordingly, both of the improvement of the transmission efficiency of the gears and an improvement of the pitting fatigue life are achieved at low cost.

  • Patent number: 10578069
    Abstract: In an information providing method and device for a vehicle, an engine of the vehicle is stopped automatically when a predetermined permission condition is satisfied in a state in which the vehicle is stopped by a brake operation executed by a driver. The driver is notified of support information for satisfying the permission condition when the permission condition is not satisfied in the state in which the vehicle is stopped by the brake operation. A vehicle stop keeping control generates a braking force capable of maintaining a vehicle stopped state even when the brake operation decreases. The notification of the support information is stopped when it is determined that the brake operation has been released and a notification continuation time has elapsed since the brake operation was released during a state in which the support information is being notified and the vehicle stop keeping control is in operation.

  • Patent number: 10576972
    Abstract: A host vehicle has an automatic brake control that is executed for avoiding contact between the host vehicle and a pedestrian upon detecting a pedestrian is present in a forward position of the host vehicle using a front camera and a radar. In a driving assist control method, upon detecting an object in front of the host vehicle to be a pedestrian candidate based on an image signal from the front camera, execution of an automatic brake control is permitted with the detected pedestrian candidate as the control target. Thereafter, whether or not the pedestrian candidate detected by the front camera matches an object detected by the reflected waves from the millimeter wave radar is determined by comparison. Execution of the automatic brake control is continued or stopped based on the result of the comparison determination.
