Automatic transmission controlling method for commercial motor vehicle, involves adjusting automatic transmission independently of supply pressure in electrical switching position of used gear during short-time switch off of engine

摘要

The method involves driving a hydraulic pump for pressure supply and cooling oil supply, using an internal combustion engine. A hydraulic system is adjusted over a transmission control device, where the hydraulic system includes a valve arrangement with directly controlled electric valves. An automatic transmission is adjusted independently of the supply pressure in an electrical switching position of a used gear during a short-time switch off of the combustion engine, where the transmission is operated in a start-stop-mode.
