1. A hybrid vehicle, comprising:

  • an internal combustion engine configured to output power for driving;

    a motor configured to output power for driving;

    an accumulator configured to transmit electric power to and from the motor;

    an accelerator operation amount detector configured to acquire an amount of a driver'"'"'s accelerator operation;

    a drive mode selector configured to select an object drive mode between a first drive mode for ordinary driving and a second drive mode having a tendency of a better response of power output to the driver'"'"'s accelerator operation than a response in the first drive mode;

    an auto cruise selector configured to give an instruction for enabling a preset auto cruise function; and

    a controller configured to, in the case of no instruction for enabling the preset auto cruise function, control the internal combustion engine and the motor to ensure output of a power equivalent to a driving force demand, which is set based on the acquired amount of the driver'"'"'s accelerator operation and a driving force setting restriction corresponding to either the first drive mode or the second drive mode selected as the object drive mode, and, in the case of the instruction for enabling the preset auto cruise function, to control the internal combustion engine and the motor to ensure output of a power equivalent to the driving force demand, which is set based on a restriction for execution of the preset auto cruise function without using a driving force setting restriction corresponding to the second drive mode, regardless of selection of either the first drive mode or the second drive mode as the object drive mode.
