Abstract
To control the speed reduction ratio SLIP of an automatic transmission and a throttle opening TA of a vehicle engine to minimize fuel consumption while satisfying the driving needs of the vehicle's driver, a target acceleration setting section sets a target acceleration GT based on a target speed VTX and an actual speed SPD selected by a target speed selection section. A target drive torque setting section sets a target drive torque TDRV based on an actual speed SPD and the target acceleration GT. The target drive torque TDRV set in this way is input to a speed reduction ratio control section, and the speed reduction ratio control section controls the speed reduction ratio SLIP and lockup state XLU of the automatic transmission so that the target drive torque TDRV is achieved and fuel consumption is minimized based on the target drive torque TDRV and the target speed VTX. A target throttle opening setting section computes and sets a target throttle opening TTA based on the actual speed SPD, the target acceleration GT, the speed reduction ratio SLIP and the lockup state XLU.
