Mobile object control apparatus and mobile object control system

A mobile object control system comprising:

• a mobile object control apparatus included in a mobile object;
• and
• a communication apparatus configured to communicate with the mobile object control apparatus, wherein
• the mobile object control apparatus includes
• a storage unit configured to store a function setting value that is a setting value of a predetermined function built into the mobile object,
• a communication unit configured to communicate with the communication apparatus outside the mobile object,
• a first control unit configured to execute a function setting value update process of changing the function setting value stored in the storage unit to an update value of the function setting value when the communication unit receives the update value, the update value being transmitted from the communication apparatus,
• a second control unit configured to change setting of the predetermined function on a basis of the function setting value stored in the storage unit,
• a power supply control unit configured to control supply of power to the communication unit, the first control unit, and the second control unit, and
• a power supply mode switching unit configured to switch the mobile object between a power-on mode and a power-off mode in response to power-on and power-off switching operations by a user of the mobile object, and
• the power supply control unit
• supplies the communication unit, the first control unit, and the second control unit with power in the power-on mode, and
• enables a communication standby state in the power-off mode, and, in the communication standby state, supplies the first control unit with power to allow the function setting value update process by the first control unit to be executed when the communication unit receives the update value of the function setting value transmitted from the communication apparatus and imposes a restriction on supply of power to the first control unit to return the mobile object control apparatus to the communication standby state after the function setting value update process by the first control unit is completed, the power supply control unit supplying the communication unit with power and imposing a restriction on supply of power to the first control unit and the second control unit in the communication standby state.
