Abstract:
A controller for a hybrid vehicle controls a first motor generator and a second motor generator such that electric power input to a battery does not exceed an input upper limit value and electric power output from the battery does not exceed an output upper limit value. The controller executes motoring to rotate an output shaft using the first motor generator with combustion operation of an engine stopped, thereby causing a braking force generated by friction of the engine to act on a driven wheel. The controller executes a valve-opening limitation process that limits an increase in a throttle open degree in correspondence with the input upper limit value upon issuance of an increase request for the throttle open degree that is not based on an operation of requesting a change in the braking force performed by a driver during the execution of the motoring.
