  • Patent number: 11102475
    Abstract: A video encoding device includes a local decode generation unit for generating a reference image based on a result of encoding of a divided image, a compression unit for compressing the reference image to generate a compressed data, a reference image storage determination unit for determining whether to store the compressed data in a memory, and an inter-prediction unit for performing motion vector search for inter-coding based on a reference image stored in the memory. The reference image storage determination unit sets an allowable data amount used for storing the reference image for each determined area of the moving image data, and determines whether or not to store the compressed data obtained by compressing the reference image in the memory based on the allowable data amount. Inter-prediction unit sets the reference image corresponding to the compressed data stored in the memory as the search range of motion vector search.

  • Patent number: 9856980
    Abstract: In a vehicular parking lock device, supplying a hydraulic pressure from pressure regulation of a line pressure by a linear solenoid valve to a hydraulic brake via a switching valve operated by a first solenoid valve enables a transmission to carry out a shift change. If desired that a parking lock is not operated when an engine stops, the hydraulic pressure stored under pressure in an accumulator is discharged to a drain oil passage by connecting the linear solenoid valve selectively to the drain oil passage by the first solenoid valve, thereby making it possible to prevent the hydraulic pressure stored under pressure in the accumulator from being supplied to a locking oil chamber at the other end of the hydraulic actuator. The first solenoid valve is used for both controlling the operation of the hydraulic brake and discharge of the hydraulic pressure stored under pressure in the accumulator.

  • Patent number: 9488269
    Abstract: A hydraulic control device for an automatic transmission includes a cut-off valve and a line pressure detector. The cut-off valve has a valve element located at one of a first position and a second position. The first position disables supply of a hydraulic fluid to a frictional engagement mechanism of the automatic transmission. The second position enables supply of the hydraulic fluid to the frictional engagement mechanism. The line pressure detector is configured to detect a line pressure. The cut-off valve is to control a hydraulic fluid passage so that the line pressure is supplied to the line pressure detector in a case where the valve element is at the first position and so that the line pressure is not supplied to the line pressure detector in a case where the valve element is at the second position.

  • Patent number: 9205813
    Abstract: In case of power supply loss, a parking lock is operated by moving a piston of a hydraulic actuator rightward by use of hydraulic pressure accumulated in an accumulator. If a hydraulic pressure generating source becomes unable to generate line pressure due to its failure after the power supply loss, it is desirable that the parking lock be releasable to tow a vehicle, for example. In that time, because the hydraulic pressure in the accumulator has got out via an orifice, the parking lock can be released by moving the piston in the hydraulic actuator leftward by use of a manual operation device without interruption by the hydraulic pressure accumulated in the accumulator. Because the hydraulic pressure in the accumulator is automatically released via the orifice, a complicated mechanism for enabling the manual operation device to work without interference from the hydraulic actuator becomes unnecessary.
