Claim 8:
9. A method for controlling power generation of an on-vehicle generator, comprising the steps of:
determining a prescribed distance or a prescribed period for charging, in an on-vehicle battery, a necessary power amount required for an update process of a control program in an on-vehicle control device;
determining whether a preparation range that starts by the prescribed distance or the prescribed period before a scheduled stop of a vehicle includes a current position or a current time of the vehicle;
in response to determining that the preparation range does not include the current position or the current time of the vehicle, setting a first threshold value for vehicle traveling;
in response to determining that the preparation range includes the current position or the current time of the vehicle, setting a second threshold value different from the first threshold value for an update of the control program; and
monitoring a power storage amount of the on-vehicle battery during vehicle traveling, and when the power storage amount is reduced to reach the first threshold value or the second threshold, instructing the on-vehicle generator, which supplies power to the on-vehicle battery, to generate power.
