DRIVE CONTROLLER OF VEHICLE

摘要

A drive controller of a vehicle capable of accurately estimating engine torque while traveling in a fixed change gear ratio mode. The drive controller of a vehicle has a gear mechanism including a rotary element rotated by torque of an internal combustion engine and a fixed element engaging with the rotary element, a torque applying means for applying the torque to the rotary element and a first transmission control means for engaging the gear mechanism thereby supporting reactive force of the torque of the internal combustion engine. A torque estimation control means controls to apply the torque from the torque applying means to the rotary element during the control of the first transmission control means to detect a change in phase of the rotation direction between the rotary element and the fixed element and estimates the torque of the internal combustion engine based on the change in phase and the torque of the torque applying means. Thus, the torque of the internal combustion engine can be accurately estimated while the rotary element and the fixed element engage with each other.
