Vehicle control apparatus

A vehicle control apparatus comprising:

• a storage apparatus in which software has been written;
• a receiver that receives updating software for updating the software;
• a power-source-remaining-capacity detector that detects power-source remaining capacity of a battery;
• a power-source-remaining-capacity decrease detector that detects a power-source remaining capacity decreasing amount of a battery;
• a software-updating-power calculator that calculates software-updating electric power for writing the updating software in the storage apparatus;
• a software-updating-starting permitter that permits starting of updating the software in the case where remaining capacity of the battery detected by the power-source-remaining-capacity detector is larger than the software-updating electric power calculated by the software-updating-power calculator;
• a software-updating-continuation permitter that permits continuation of updating the software in the case where a power-source remaining capacity decreasing amount of the battery is smaller than a predetermined decrease determination value;
• and
• a software-updating controller that starts writing the updating software in the storage apparatus in the case where the software-updating-starting permitter permits starting of software updating, that continues writing the updating software in the storage apparatus in the case where during writing the updating software in the storage apparatus, the software-updating-continuation permitter permits continuation of software updating, and that interrupts writing the updating software in the storage apparatus in the case where the software-updating-starting permitter or the software-updating-continuation permitter determines not to provide permission.
