An ECU executes a program including a step of detecting a running speed of a vehicle and a current gear stage of the vehicle, a step of determining whether or not shifting is required, a step of calculating a required period T(D) for performing double clutch control if shifting is required, a step of calculating a required period T(S) for synchro-rotational synchronization, a step of determining whether or not the required period T(D) for double clutch control is equal to or shorter than the required period T(S) for synchro-rotational synchronization, and a step of carrying out shifting by performing double clutch control if the required period T(D) for double clutch control is equal to or shorter than the required period T(S) for synchro-rotational synchronization. A sense of incongruity felt by a driver during shifting is thereby suppressed.

In a braking-force generator: a master cylinder generates first braking force corresponding to an operational input through a manipulator; a hydraulic-pressure generator connected to the master cylinder through a shutoff valve generates second braking force corresponding to the operational input through the manipulator when the shutoff valve is closed; an abnormality detector repeatedly determines whether or not an operational state of the hydraulic-pressure generator is abnormal; and a controller prohibits generation of the second braking force, opens the shutoff valve, and transmits the first braking force to the hydraulic-pressure generator, when the operational state is abnormal. In the case where the abnormality detector determines that the operational state changes from an abnormal state to a normal state while manipulation with the manipulator is being performed, the controller keeps prohibition of the generation of the second braking force and keeps the shutoff valve open until the manipulation is terminated.

A driving assist system assists steering such that a vehicle travels along a set target course. A steering torque sensor detects a steering torque that serves as a steering operation input value generated by a driver. If the steering torque value is equal to or greater than a preset reference value and a direction corresponding to the steering torque is a direction away from another vehicle present ahead in an adjacent lane, then an ECU corrects the target course to a course that moves away from the other vehicle.

An image decoding apparatus includes an information acquisition section that acquires information of a bit-plane truncation position in an encoded stream from the encoded stream generated by performing bit-plane encoding on a transform coefficient, a decoding process section that performs a decoding process on the encoded stream and generates a transform coefficient, and a significant coefficient detection section that detects whether the transform coefficient generated in the decoding process section is significant. The image decoding apparatus includes a correction value acquisition section that acquires a correction value corresponding to the bit-plane truncation position in the transform coefficient detected to be significant, from a correction value table, and a coefficient correction processing section that performs coefficient correction processing on the transform coefficient using the correction value acquired in the correction value acquisition section only for the transform coefficient detected to be significant in the significant coefficient detection section.

A first-screen is continuously displayed on a display according to contents of the first-screen, in a case where a first display request is cancelled before a continuous display time in which the first-screen based on the first display request has been continuously displayed on the display, reaches a predetermined reference time. Meanwhile, after display of the first-screen has been continued and before the continuous display time of the first-screen reaches the reference time, in a case where a second display request making an instruction for displaying a second-screen to be displayed at a highest priority occurs, the display is switched from the first-screen to the second-screen at a time when the second display request occurs, and, in a case where the second display request does not occur, the first-screen is displayed on the display until the continuous display time of the first-screen reaches the reference time.

A target reaching rotational speed set during a torque phase is set to a value higher than an actual engine rotational speed, the value being higher as one of a vehicle acceleration and an engine rotational speed gradient is larger. That is, as the acceleration is steeper, the target reaching rotational speed is set to a value closer to an upper limit rotational speed or rotational speeds proximate thereto. Thus, a display rotational speed displayed on a tachometer at the end of the torque phase becomes high rotational speed. Accordingly, there is provided a display control device for a vehicle that enables a driver to feel the use of engine performance to the limit.
