Method for operating an automatic or semi-automatic transmission of a heavy vehicle when in idle-driving mode |
摘要 |
A method for operating a semi-automatic or automatic mechanical transmission of a heavy truck when driving at idle speed is provided. The method includes supplying fuel to the engine of the heavy truck at a rate that facilitates engine-idle operation. In another step, the method engages the automatic or semi-automatic transmission in a gear higher than the starting gear of the transmission and permits the truck to operate at a first substantially uniform driving velocity under engine-idle power. Depending upon traffic and environmental requirements which require a higher speed, the driver upshifts the semi-automatic or automatic transmission by depressing a control device for manual gear selection arranged on a gear shift lever of the truck and then drives the truck at a second substantially uniform driving velocity under engine-idle power. The second substantially uniform driving velocity is greater than the first substantially uniform driving velocity. |
