Method for controlling powertrain for motor car, involves calculating vehicle data e.g. slope, speed and rolling resistance, powertrain data e.g. rotation speeds, and track information e.g. altitude and driving line in control unit

摘要

The method involves issuing (2) a request for switching off the combustion engine. A grip is interrupted (8) by hydraulically actuatable coupling arrangement between engine and gearbox. The engine is switched OFF (12) in a coasting mode. A request for switching ON the engine is issued (14) to control unit, and the engine is started (24) by producing (28) the grip. The vehicle data (6) such as slope, speed and rolling resistance, powertrain data such as translation and rotation speeds, and track information such as altitude and driving line are calculated in control unit. An independent claim is included for a powertrain for motor car.
