Abstract:
1. A control apparatus for a hybrid vehicle in which a conversion device that converts thermal energy to kinetic energy, a first driving force source that has a function of generating electric power, and an output member are connected to each other through a power splitting mechanism that produces a differential effect; a second driving force source is connected to the output member through a transmission in which a gear ratio can be changed; and a manual changing device that changes, according to manual operation, a driven state of the output member that depends on a driving state of the conversion device and a driving state of the second driving force source is provided, comprising: a first detection device which detects required driving force of the vehicle; a second detection device which obtains a required output value that is a value of required output of the second driving force source, based on the detected required driving force when the driven state of the output member that depends on the driving state of the conversion device and the driving state of the second driving force source is changed by the manual changing device; a comparison device which compares the obtained required output value to an upper limit value of output that can be transmitted to the output member from the second driving force source at the gear ratio of the transmission after the driven state of the output member is changed; and a shifting control device which adjusts the gear ratio of the transmission so as to increase the upper limit value when the obtained required output value is greater than the upper limit value.
