DRIVING FORCE CONTROL DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a driving force control device capable of ensuring the driveability without giving any sense of incongruity to a driver.

SOLUTION: The driving force control device (20) controls the driving force of a vehicle according to the driving condition of the vehicle. The driving force control device comprises an acceleration command value operation means (50) to set the final acceleration command value (cACC_end) based on the driving condition of the vehicle, a driving torque command value operation means (60) to set the target driving torque (cTDR) of the vehicle based on the final acceleration command value (cACC_end), and a driving force distribution means (80) to set the target engine torque (cTE) of an engine and the target speed change ratio (cRATIO) of a transmission based on the target driving torque (cTDR). The acceleration command value operation means (50) sets the final acceleration command value (cACC_end) by dividing the acceleration command value (cACC) by the torque amplification ratio (Tconvr) set from the engine speed (aNE) and the transmission input shaft rotation number (aNpri).
