| 发明名称 | Method for operating a powertrain in a motor vehicle | ||
| 摘要 | A method is provided for operating a powertrain in a motor vehicle, the powertrain having an internal combustion engine and components for coupling the internal combustion engine to the drive wheels of the motor vehicle in a controllable manner. The internal combustion engine is decoupled from the drive wheels if specified operating conditions are present while the motor vehicle is traveling in order to allow the vehicle to coast. Further, a rotational engine speed is set to a specified target idle speed. The target idle speed is specified in a variable manner depending on the situation. | ||

| 主权项 | 1. A method for operating a motor vehicle powertrain having an internal-combustion engine and components for coupling the internal-combustion engine to drive wheels of the motor vehicle in a controllable manner, the method compromising the acts of: when the motor vehicle is traveling, decoupling the internal-combustion engine from the drive wheels under predefined operating conditions in order for the motor vehicle to coast, wherein a rotational engine speed of the internal-combustion engine is set to a predefined desired rotational idling speed, and the predefined desired rotational idling speed is variably predefined as a function of a situation of the motor vehicle. | ||
