  • Publication number: 20170267247
    Abstract: A vehicle capable of regenerative braking includes a motor that is configured to be driven with electric power. The vehicle selectively sets a drive mode of the vehicle in an accelerator-off state between an ordinary mode and a deceleration enhanced mode that decelerates the vehicle with higher deceleration force than deceleration force in the ordinary mode. The vehicle performs regenerative control of the motor in the ordinary mode or performs deceleration control of generating the deceleration force in the deceleration enhanced mode, in order to decelerate the vehicle in the set drive mode. When an accelerator stroke based on a driver's depression of an accelerator becomes higher than a cancellation threshold in the drive mode set to the deceleration enhanced mode, the cancellation threshold being determined in advance corresponding to the accelerator stroke being greater than zero, the vehicle changes the drive mode from the deceleration enhanced mode to the ordinary mode.

    Abstract: 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.
