DRIVE FORCE CONTROL DEVICE

摘要

Provided is a drive force control device (100) which controls a drive force of a vehicle (1) by controlling an engine torque generated by an internal combustion engine (10) mounted on the vehicle (1) and an engine rpm of the internal combustion engine (10) according to an operation amount of the drive force request operation for the vehicle (1). When an operation point of the internal combustion engine (10) based on the engine torque and the engine rpm is in an optimal fuel consumption band (X) as a region set with a predetermined hysteresis width (a) for an optimal fuel consumption line (L) of the internal combustion engine (10), a rotation fluctuation suppression control is executed to suppress fluctuation of the engine rpm, which improves efficiency of the entire drive system.
