DRIVE CONTROL DEVICE FOR A VEHICLE

摘要

There is provided a drive control device for a vehicle capable of estimating an engine torque with high accuracy during traveling in a fixed gear ratio mode. The drive control device includes the engagement mechanism including the revolution component that is revolved by the torque of the internal combustion engine and the fixed component that engages with the revolution component, the torque applying unit which applies the torque to the revolution component and the first transmitting control unit which engages the engagement mechanism to make the engagement mechanism receive the reaction force of the torque of the internal combustion engine. The torque estimating control unit executes the control of the torque applied to the revolution component by the torque applying unit during executing the control by the first transmitting control unit thereby to detect the phase change between the revolution component and the fixed component in a direction of rotation, and estimates the torque of the internal combustion engine based on the phase change and the torque applied by the torque applying unit. Therefore, it becomes possible to estimate the torque of the internal combustion engine with high accuracy in such a state that the revolution component and the fixed component are engaging.
