<p>PROBLEM TO BE SOLVED: To provide a vehicle driving force control device attaining the improvement of a target operability by sufficiently suppressing generation of a driving force step difference by operating a variable speed ratio of a continuously variable transmission when changing over an engine driving state. SOLUTION: This vehicle driving force control device is provided with an engine driving state changeover command means 1, an engine torque detecting means 2, a variable speed ratio detecting means 3 detecting the variable speed ratio of the continuously variable transmission 9 connected to the engine 10, a car speed detecting means 4, a variable speed ratio correcting quantity calculating means 5 calculating a variable speed ratio correcting quantity hRatio of the continuously variable transmission 9 considering inertial between the engine 10 and the continuously variable transmission 9 based on the engine driving state changeover command, the engine torque, the variable speed ratio, and the car speed, a first target variable speed ratio setting means 6 setting a first target variable speed ratio of the continuously variable transmission 9, a second target variable speed ratio calculation means 7 calculating a second target variable speed ratio from the first target variable speed ratio and the variable speed ratio correcting quantity hRatio, and a variable speed ratio operation means 8 operating the variable speed ratio of the continuously variable transmission 9 so as to obtain the second target variable speed ratio.</p> |
