Abstract
An automobile is equipped with a gear type transmission having a first torque transfer path between input and output shafts formed by mesh type clutches and a second torque transfer path between input and output shafts formed by transfer torque variable systems, and actuators for selecting the torque transfer path. When a wheel slips while the automobile is driving using the first torque transfer path, the actuators are controlled so that at least part of the torque being transferred via the first torque transfer path is instead transferred via the second torque transfer path.
