Abstract: A control device of an engine includes an adjustment mechanism and a controller. The adjustment mechanism is configured to adjust an intake air amount. The controller is configured to save a first learning value in a volatile storage medium, the first learning value being obtained by learning an operation amount of the adjustment mechanism when the engine is idle. The controller is configured to control the adjustment mechanism according to the first learning value. The controller is configured to save a second learning value in a non-volatile storage medium, the second learning value being equal to the first learning value. The controller is configured to correct the first learning value using the second learning value after the first learning value is cleared.

Abstract: Provided is an abnormality determination device of a vehicle including an engine and a first motor that is configured to output a torque to an output shaft of the engine, the abnormality determination device determining an output abnormality of dropping output of the engine in the vehicle. The abnormality determination device has an abnormality determination unit that determines that an output abnormality of the engine has occurred when an actual torque that is estimated, based on a torque of the first motor, as a torque actually output from the engine falls below a lower limit of an allowable range for a target torque to be output from the engine, and when an amount of increase in a rotational speed of the engine is smaller than a threshold value for misdetermination suppression, which is a threshold value that is larger as the target torque is higher.
