PROBLEM TO BE SOLVED: To suppress the occurrence of hunting of a vehicle speed even if a second driving force control for setting a target input shaft rotational speed of a continuously variable transmission on the basis of an optimum fuel consumption line while a first driving force control is being executed for setting the target input shaft rotational speed of the continuously variable transmission on the basis of a relationship between the vehicle speed and an accelerator opening degree without need to make an engine operating point along the optimum fuel consumption line.SOLUTION: If a first driving force control is switched to a second driving force control during the first driving force control, a driving force control is exerted with a latest target input shaft rotational speed Nintgt set during the first driving force control as the target input shaft rotational speed Nintgt set during the second driving force control. If the first driving force control is executed again even when the second driving force control is executed during the first driving force control, the target input shaft rotational speed Nintgt is not changed. Owing to this, it is possible to suppress hunting of a vehicle speed V due to the re-execution of the first driving force control by the change of the target input shaft rotational speed Nintgt due to the execution of the second driving force control.SELECTED DRAWING: Figure 7 |
