Drive force control device for vehicle

摘要

A target drive force is computed according to an accelerator pedal opening. A target input rotation speed lower limit basic value to an automatic transmission is computed based on a vehicle speed and a shift range of the automatic transmission. A target drive force lower limit correction value is computed based on the target input rotation speed lower limit basic value. The target drive force is corrected based on the target drive force lower limit correction value. A target input torque of the automatic transmission is computed based on the target drive force after correction. An input torque to the automatic transmission is controlled to the target input torque. By this control, an arbitrary drive force characteristic can be obtained in a PTD control.
