摘要:
A vehicle drive control for a wheeled vehicle including a first motor generator, and a second motor generator. A planetary gear set includes a first rotating element connected to the first motor generator, a second rotating element connected to the second motor generator, and a third rotating element connected to a drive wheel. A rotation control mechanism selectively restricts rotation of one of the first and second rotating elements of the planetary gear set to establish a fixed speed ratio mode, and releases the one of the first and second rotating elements to establish a variable speed ratio mode. A control unit is configured to control each operating state of the rotation control mechanism, the first motor generator, and the second motor generator, and configured to establish the variable speed ratio mode when a slip state of the drive wheel is detected in the fixed speed ratio mode.
