At the time of low temperature starting in vehicle drive train protective method

摘要

This invention at the time of low temperature starting in the vehicle drive train regards protective method. When temperature is less than the ru specified temperature limit which the normal time of the engine is lower than operation temperature, largest approved engine torque and/or the highest approved engine rpm speed is restricted (T1, n1, T2 and n2,4,5,6,7), while restricting which because of this at least at the time of low temperature starting of one side of the aforementioned engine and the aforementioned transmission is adapted to sensitivity the drive train operation area is demarcated. Transmission control is suitable, although automatically while restricting the engine operation area is made effective. Selective figure Figure 1
