METHOD AND ARRANGEMENT FOR ADAPTING SHIFTING STRATEGIES IN A HEAVY VEHICLE INCLUDING AN AUTOMATED TRANSMISSION AND EXPERIENCING A PTO LOAD |
摘要 |
Method and arrangement for adjusting shift characteristics of a transmission of a heavy vehicle. A heavy vehicle is operated and that is powered by an internal combustion engine equipped with an automated manual transmission and a power take off. The power take off, when operating, imposes a torque-consuming load on the engine. Operation of the power take off is detected when the engine of the vehicle is in a power mode. At least one gear-shift event is adapted to occur at a higher engine speed when power take off operation is detected than when power take off operation is not detected. The gear-shift event is affected at an engine speed that is approximately five to twenty-five percent higher than when power take off operation is not detected. The gear-shift event may be an up-shift to a lower ratio gear engagement or a down-shift to a higher ratio gear engagement. |
