First and second clutches correspond to systems which include “first gear” and “second gear,” respectively. When the temperature of the first clutch at the time of start of the vehicle is lower than a first temperature, only the first clutch is used as a start clutch for driving the vehicle. When the temperature of the first clutch is not lower than the first temperature but is lower than a second temperature, both the first and second clutches are used as the start clutch. When the temperature of the first clutch is equal to or higher than the second temperature, only the second clutch is used as the start clutch. Thus, the higher the temperature of the first clutch, the smaller the load acting on the first clutch. When the temperature of the second clutch is high, engine torque is reduced, and a warning is issued.

The influence of queuing delay in routing calculation is considered. A queue element is defined, and a queue scheduling mechanism is put forward. In order to avoid the problem that a path selected cannot forward a message, the influence of contact capacity is considered.

The number of redundant message copies in the network can be reduced, and the average transmission delay of messages and the network load rate can be reduced. The residual capacity is sufficient for transmitting messages. The path with the lowest delay is taken as a reference path. Thus, the method better adapts to some sudden faults in the process of communication.
