  • Controller and control method for vehicle
    Patent number: 11536169
    Abstract: A controller for a vehicle that includes an internal combustion includes processing circuitry. The processing circuitry obtains a predicted temperature outside the vehicle and estimates the viscosity of a lubricating oil based on the oil pressure and the oil temperature of the lubricating oil when the internal combustion engine satisfies a specific operation condition. When the processing circuitry determines that there is a likelihood of a cranking failure occurring in the internal combustion engine on condition that the predicted temperature is less than a threshold value that is based on the viscosity, the processing circuitry outputs a notification signal indicating that that there is a likelihood of a cranking failure occurring in the internal combustion engine.
