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.

In a state where steering request torque is being output (S1: YES), the steering request torque is cancelled (S12) on the basis of continuation of a state where driver torque is being input (S11: YES). A cancel delay time indicating the length of time between the input of driver torque and the cancellation of the steering request torque is shortened when the driver torque is not less than a second timer ON threshold value compared with when the driver torque is between a first timer ON threshold value and the second timer ON threshold value. Thus, when the driver turns the steering wheel quickly and a large torque is input, the control torque is cancelled in a short time, whereby quick steering corresponding to the driver's steering wheel operation is performed. As a result, the sense of discomfort the driver feels can be suppressed.

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.
