Abstract
A driving force control system is provided for an automotive vehicle powertrain. In the driving force control system, an ordinary (or base) target driving force (tTd#n) is determined in response to operator depression of an accelerator (APO) and vehicle speed (VSP). A driving force correction (ADDFCE) is determined in response to a running resistance increment. The driving force correction is added to the ordinary target driving force to provide a first corrected target driving force (tTde) to an engine torque control The driving force correction is multiplied with a correction coefficient (&agr;) to provide a corrected driving force correction. The corrected driving force correction is add to the ordinary target driving force to provide a second corrected target driving force (tTdr) to a CVT ratio control.
