PROBLEM TO BE SOLVED: To restrain the occurrence of the situation of excessively raising the temperature of a clutch, when a vehicle starts, in a power transmission control device of the vehicle of using a double clutch transmission.SOLUTION: First and second clutches C1 and C2 correspond to systems including a "first speed" and a "second speed" respectively. When the vehicle starts, when the temperature of the first clutch C1 is less than the first temperature T1, only the first clutch C1 is used as a starting clutch used for driving the vehicle. When the temperature of the first clutch C1 is the first temperature T1 to the second temperature T2, both the first and second clutches C1 and C2 are used as the starting clutch. When the temperature of the first clutch C1 is the second temperature T2 or more, only the second clutch C2 is used as the starting clutch. Thus, as the temperature of the first clutch C1 becomes high, a load received to the first clutch C1 is further reduced. When the temperature of the second clutch C2 is further high, engine torque is reduced and a warning is issued. |
