DRIVING FORCE CONTROL SYSTEM FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To improve power control performance and engine performance in balance when compensating an automatic transmission for late transmission by operating an engine through setting an allowable line through calculating a first target engine torque then determining a second target engine torque that is corrected to fall under the allowable value. SOLUTION: A first engine torque calculation means 8 determines a first target engine torque from a target driving force and a gear ratio of an automatic transmission 6. A second target engine torque calculation means 9 first determines a target engine torque allowable value from engine speed detected by an engine speed detecting means 12, and then calculates a second target engine torque from the first target engine torque and the target engine torque allowable value so that the first target engine torque falls under the allowable value. Then a fuel injection amount is adjusted so as to near the second target engine torque. As a result, power control performance and fuel consumption performance are improved in balance.
