CONTROL DEVICE OF HYBRID VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a control device of a hybrid vehicle that can estimate the engine torque of the engine that drives an engine driving shaft by using the torque of the motor that drives the motor driving shaft.

SOLUTION: The control device of the hybrid vehicle includes: an engine information detection means (steps S5-S8 and steps S10-S13) that detects the engine state information that has the proportional relation to the engine torque, and is displayed by the proportion to the maximum engine torque; a conversion factor calculating means (steps S14-S19) that calculates the conversion factor which converts the engine state information into the engine torque based on the variation of the motor torque when the motor torque is changed by the prescribed amount in a state where the total driving force of the vehicle is maintained constant and the variation of the engine state information according to the change in the motor torque; and an engine torque calculating means (steps S20-S23) that calculates the engine torque based on the conversion factor and the engine state information.
