Abstract:
1. A control apparatus for a vehicle that includes an internal combustion engine, a catalyst for purifying an exhaust gas of the internal combustion engine, a storage device charged with an electric power from a power supply outside the vehicle, and a rotational electrical machine driven by an electric power of the storage device, and that has, as running modes, a first mode in which the vehicle runs with an aid of a motive power of the rotational electrical machine with the internal combustion engine stopped in principle so as to give higher priority to consumption of the electric power of the storage device than to conservation thereof and a second mode in which the vehicle runs with an aid of a motive power of the internal combustion engine and a motive power of the rotational electrical machine with the internal combustion engine operated according to need so as to give higher priority to conservation of the electric power of the storage device than to consumption thereof, comprising: a control portion that performs intermittent control to intermittently operate the internal combustion engine in accordance with a required discharge amount, namely, an amount of an electric power to be discharged from the storage device even in the first mode when a predetermined condition on warm-up of the catalyst is fulfilled during the first mode; and a calculation portion that calculates the required discharge amount on a basis of a temperature of the internal combustion engine when the intermittent control is performed during the first mode.
