Title:
DRIVE TORQUE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/002033
Kind Code:
A1
Abstract:
Provided is a drive torque control device capable of suppressing a drive torque error in the actual drive torque relative to the torque command value in a drive unit even during a period other than when travelling in a straight line. The drive torque control device is characterized in that a vehicle controller (11) is provided with a portion that executes a process illustrated in a flowchart shown in Fig. 3B for correcting a torque command value (tTm) to be outputted to the electric motor (3) of at least one of the left and right drive units (WD, WD) on the basis of lubricant temperature (To), motor temperature (Tmo), and pump lubricant amount (Ov), which are drive-torque shift factors causing the actual drive torque to shift from the target drive torque for the right and left drive units (WD, WD), said correction being carried out so that the torque difference between the actual drive torque of the left drive unit (WD) and the actual drive torque of the right drive unit (WD) approaches the torque difference between the right and left drive units (WD, WD) when no torque difference exists between the target drive torque and the actual drive torque in the right and left drive units (WD, WD).
