An engine control device for controlling an engine of a vehicle includes a microcomputer for executing an engine control process, and an abnormality detection unit for detecting an abnormality of the microcomputer. A reset execution unit executes a process of causing an external monitor IC to reset the microcomputer on condition that the abnormality of the microcomputer is detected and an engine rotation speed is higher than a threshold engine speed value. The microcomputer may alternatively be reset on condition that a vehicle speed is higher than a threshold vehicle speed value, or that all or a part of torque output from the engine is able to be supplemented by another vehicle drive power source.

Systems and methods for operating a vehicle that may be driven to or sold in different geographical locations that may have different engine emissions and fuel economy standards are described. The systems and methods may adjust vehicle operation to comply with standards that may be enforced where the vehicle is geographically located. The standards may apply to countries, treaty zones, race track areas, off-road areas, and other geographically related standards.
