  • Patent number: 11932137
    Abstract: A regenerative torque upper limit is set to a larger value when a rear-wheel distribution ratio is small than when the rear-wheel distribution ratio is large. Accordingly, when a distribution of a drive power to front wheels is large, a regenerative torque of a second rotary machine can be increased such that wheels are less likely to slip at the time of performing of regeneration control when the distribution of the drive power to the front wheels is small in comparison with a case in which the regenerative torque upper limit is set to a constant value similarly to when the distribution of the drive power to the front wheels is small. In this way, it is possible to increase the regenerative torque of the second rotary machine according to the rear-wheel distribution ratio.

  • Publication number: 20240067158
    Abstract: A vehicle including an internal combustion engine and an automatic transmission capable of transmitting and receiving torque to and from an output shaft of the internal combustion engine is controlled. During operation of the internal combustion engine, a process that calculates a diluted water amount based on an operation state of the internal combustion engine is executed. The diluted water amount is the amount of water contained in lubricating oil in the internal combustion engine. Further, a process that controls the automatic transmission such that torque per unit period in the internal combustion engine becomes smaller when the diluted water amount is relatively large compared to when the diluted water amount is relatively small, while continuing the operation of the internal combustion engine, is executed.

  • Patent number: 11592296
    Abstract: The purpose is to provide a nautical chart display device which enables a measurement of a distance on an electronic nautical chart, like a measuring method which is performed by using a divider. The nautical chart display device includes a display unit, an operation detector, a registration processing module, and a change processing module. The display unit has a screen and displays a nautical chart on the screen. The operation detector detects a touch operation to the screen. The registration processing module accepts two points of the touch operation on the screen, and registers a scale at which a distance between the touched points on the screen matches a distance setting on the nautical chart as an additional scale. The change processing module changes the scale of the nautical chart to the additional scale.

  • Patent number: 11572235
    Abstract: An aligner device includes a robot hand, a lifting mechanism, sensors, a misalignment calculating unit, an x-y misalignment correcting unit, and a ? misalignment correcting unit. The robot hand includes vertically aligned hand members each configured to hold a planar workpiece. The lifting mechanism moves planar workpieces transported by the robot hand up from and down to the hand members, respectively. Each of the sensors, vertically spaced apart from each other, has a downward sensor surface to capture the outline of a planar workpiece brought close to the sensor surface by the workpiece lifting mechanism. The misalignment calculating unit calculates, by using the images of the captured outline shapes of the planar workpieces, an amount of positional misalignment of each planar workpiece with a reference position in X, Y and ? directions.
