Driving force control device

A driving force control device, which controls a gear ratio of an automatic transmission to thereby achieve a target driving force calculated by an onboard control device, said driving force control device comprising:

• vehicle speed sensor for detecting a vehicle speed;
• throttle opening sensor for detecting a throttle opening;
• virtual throttle opening converter for calculating a driving force that is outputted from said automatic transmission according to a predetermined shift map based on the vehicle speed and the throttle opening, setting a target driving force characteristic whose parameters are the vehicle speed and the throttle opening according to a result of the calculation, and converting said target driving force into a virtual throttle opening by using said target driving force characteristic and the detected vehicle speed;
• throttle opening information selector for selecting the virtual throttle opening from said virtual throttle opening converter as throttle opening information when a driving force is controlled, and selecting an actual throttle opening from said throttle opening sensor as throttle opening information when a driving force is not controlled;
• and
• target shift value calculating means for calculating a target shift value according to the selected throttle opening information, the detected vehicle speed value and said predetermined shift map.
