Claim 0:
1. A control device comprising:
an in-vehicle communication unit capable of communicating with an on-vehicle control device; and
a control unit configured to control the in-vehicle communication unit, wherein the control unit monitors a power storage amount of an on-vehicle battery during vehicle traveling, and executes a charge control for causing the in-vehicle communication unit to transmit an instruction of power generation to an on-vehicle generator that supplies power to the on-vehicle battery, when the power storage amount is reduced to reach a threshold value regarding a power amount, and
the control unit determines a prescribed distance or a prescribed period for charging, in the on-vehicle battery, a necessary power amount required for an update process of a control program in the on-vehicle control device,
the control unit determines 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, the control unit sets a first threshold value for vehicle traveling, and executes the charge control, and
in response to determining that the preparation range includes the current position or the current time of the vehicle, the control unit sets a second threshold value different from the first threshold value for an update of the control program, and executes the charge control.
