PROBLEM TO BE SOLVED: To suppress an excess rotation of a first motor when an automobile is moved in reverse.SOLUTION: In a control scheme in which an upper limit rotation speed Nm1 max of a first motor is set so as to allow a higher rotation speed when a shift position SP is at an R-position than when the shift position is at a D-position within a range of less than an excessive rotation-determining speed of the first motor, upper-limit torque Tm1 max is set so that a rotation speed Nm1 of the first motor is decreased from the upper limit rotation speed Nm1 max in a greater degree with the shift position SP at the R-position than with the shift position at the D-position, when a rotation speed Nm1 of the first motor approaches the upper limit rotation speed Nm1 max. Further, a torque instruction of the first motor is set within the upper-limit torque Tm1 max so as to control the first motor. |
