Document Type and Number:
Japanese Patent JP2020040449
Kind Code:
A
Abstract:
To provide a control device of a hybrid vehicle that is capable of determining abnormality of an engine, without installing a sensor for detecting engine torque, such as a torque sensor.SOLUTION: Provided is a control device of a hybrid vehicle which includes an engine and a motor as drive force sources, and in which an output ratio to the engine out of a command drive force for driving the vehicle, and an output ratio to the motor can be changed. The control device has a controller for controlling an output torque of the engine and the motor. The controller is configured to determine that abnormality has occurred in the engine, in the case that a relationship between the command drive force and vehicle speed when the output ratio to the motor is set to a first predetermined value, and a relationship between the command drive force and vehicle speed when the output ratio to the motor is set to a second predetermined value are different (step S15).SELECTED DRAWING: Figure 5
