VEHICULAR DRIVE FORCE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To suppress a vehicular under-steer state while suppressing deterioration in vehicular drivability.SOLUTION: A method includes: computing a target reduction correction amountΔFv of a drive force of vehicle for reducing a vehicular under-steer state at every given time (S20) when the vehicular under-steer state reaches or exceeds a predetermined degree (S40); computing a target transmission ratio Rgt of a step-less transmission corresponding to a target minimum drive force of the vehicle for reducing a vehicular under-steer state on the basis of the target reduction correction amount (S140, 150); computing an increasing correction amount of rotary drive force of an engine 12 on the basis of the target reduction correction amount (S170) while controlling a transmission ratio of the step-less transmission so as to reach the target transmission ratio (S160); and controlling rotary drive force of the engine 12 on the basis of the increasing correction amount (S180).
