PROBLEM TO BE SOLVED: To provide a drive control device which can suppress the excessive rotation of an electric motor even if it cannot be determined whether or not the electric motor is excessively rotated.SOLUTION: In a drive control device which is mounted to a hybrid vehicle having a gear mechanism in which an output shaft of an engine, a rotor shaft of an MG1, a rotor shaft of an MG2, and a drive shaft which can transmit power to drive wheels are connected to one another, at least one of a current engine rotation speed Ne being an engine rotation speed Ne_mg1max when a rotation speed Nmg1 of the MG1 becomes an upper limit rotation speed Nmg1max, an engine rotation speed Ne_mg2min when a rotation speed Nmg2 of the MG2 becomes a lower limit rotation speed Nmg2min, and an engine rotation speed Nemax being an upper limit rotation speed of the engine is equal to or more than the engine rotation speed, lowering control for lowering the engine rotation speed Ne is performed. |
