Abstract

In a drive control system for a vehicle configured to cause the vehicle to travel in a limp-home mode when a malfunction occurs in a selectable one-way clutch, when it is determined that a malfunction occurs in the SOWC, the cause of the malfunction is specified as one of a plate-open failure of a selector plate that is unintentionally placed in an open state, and a sensor failure. In the case of the plate-open failure, a first limp-home traveling mode is carried out in which the vehicle travels in the limp-home mode while keeping the SOWC in a negative rotational speed range. In the case of the sensor failure, a second limp-home traveling mode is carried out in which the vehicle travels in the limp-home mode while the SOWC is placed in the non-engaged state.
