摘要
A CPU mounted on a vehicle obtains positional data by the GPS. Next, the CPU identifies an octane number, which is a parameter related to combustion of fuel, on the basis of the positional data corresponding to the position of the vehicle and the date and time at which the positional data was obtained. Then, the CPU calculates a correction amount on the basis of the identified parameter. The CPU assigns, to ignition timing, a value calculated on the basis of the correction amount. The CPU controls an ignition device so that the ignition device generates spark discharge at the calculated ignition timing.
