Abstract
A transmission control apparatus detects a drop in power transmission performance of a clutch actuator, and prevents a failure thereof. When power transmission performance drop detecting means detects a drop in power transmission performance of a first clutch even if a power transmission instruction is given to a first clutch actuator, power transmission in a power transmission path through a first geared transmission mechanism is inhibited, and power transmission in a power transmission path through a second geared transmission mechanism is carried out. When the power transmission performance drop detecting means detects a drop in power transmission performance of a second clutch even if the power transmission instruction is given to a second clutch actuator, power transmission in the power transmission path through the second geared transmission mechanism is inhibited, and power transmission in the power transmission path through the first geared transmission mechanism is carried out.
