Abstract
A vehicle control apparatus includes: an accessory that adjusts torque that is output from an internal combustion engine, by giving load to the internal combustion engine; an ignition timing control portion that is provided so as to adjust ignition timing of the internal combustion engine, and that adjusts the torque output from the internal combustion engine by performing a retardation control of the ignition timing; an accessory load adjustment portion that adjusts an accessory load that is the load given from the accessory to the internal combustion engine; and a catalyst that purifies exhaust gas discharged from the internal combustion engine. The ignition timing control portion reduces the retardation of the ignition timing with increase in temperature of the catalyst. The accessory load adjustment portion increases the accessory load with increase in the temperature of the catalyst.
