Method and device for adapting strategies gearshift in a vehicle or heavy, comprising an automatic transmission and a load subjected PTO.

摘要

Procedure for adjusting the characteristics of speed change of a transmission (40) of a truck (10), the method comprising: operating a heavy vehicle (10) that is driven by an internal combustion engine (15) having an automated manual transmission (40) and a power output (25) whose output power (25), when it is operating, imposes a torque-consuming load to the motor (15, 70); detect the operation of the power output (25) when the motor (15) of the vehicle (10) is in a power mode (72); characterized in that it is adapted at least to take place an event shifting passing a higher engine speed when the activity of a power take in the case where not detected (74) activity a is detected PTO.
