Internal Combustion Engine Control Device and Control System for Mobile Object

A control system for a mobile object, the control system comprising:

• an internal combustion engine control device that controls an internal combustion engine for the mobile object, the internal combustion engine including an intake device that guides intake air into a cylinder through an intake passage, a fuel supply device that supplies fuel, and an ignition device that ignites an air-fuel mixture including the intake air and the fuel;
• and
• a communication device that mediates communication between an external device outside the mobile object and the internal combustion engine control device,
• wherein the internal combustion engine control device includes:
• an ignition device temperature estimation unit that measures or estimates a current temperature of the ignition device and estimates a future temperature that is a temperature of the ignition device on a future path based on information regarding a current state of the mobile object;
• an adjuster that adjusts a control instruction of at least any one of the ignition device, the fuel supply device, and the intake device in accordance with the current temperature and the future temperature;
• and
• a current parameter observation unit that measures or estimates a current parameter related to the current state of the mobile object,
• the adjuster includes:
• a prediction parameter acquisition unit that acquires a prediction parameter regarding a state of the mobile object on the future path through communication connection to the external device using the communication device;
• and
• a future parameter prediction unit that predicts a plurality of future parameters related to the state of the mobile object on the future path based on the prediction parameter and the current parameter, and
• the ignition device temperature estimation unit estimates the future temperature based on the current temperature, the plurality of current parameters, and the plurality of future parameters.
