<p>PROBLEM TO BE SOLVED: To change the driving force according to road surface gradient by controlling at least one of an engine and an automatic transmission so as to realize a corrected target driving force obtained by correcting a general target driving force with a weight gradient resistance force. SOLUTION: A PCM 111 comprises a general target driving force setting part 161, a weight gradient resistance estimation part 154, a driving force correcting quantity arithmetic part 162, an engine torque control part 169, a target input and output rotating speed arithmetic part 165, a CVT input and output rotating speed ratio control part 167, an adder part 163, and a multiplier part 168. The PCM 11 performs the control of fuel feed quantity or ignition timing of an engine 102 and the control of gear ratio or hydraulic pressure of a CVT 103. In an uphill slope, the value obtained by adding a driving force correction quantity &Delta RFORCE according to the gradient to a general target driving force tTd-n corresponds to a target driving force tTd, and the engine 102 and the CVR 103 are controlled so as to realize the target driving force tTd.</p> |
