摘要:
The present invention pertains to a method for the regulation of a temperature in an exhaust stream in a motor vehicle through control of its driveline, the motor vehicle of which comprises: a driveline comprising a combustion engine which may be connected to a gearbox via a clutch device and an exhaust system arranged for the removal of an exhaust stream from the said combustion engine; where the said method comprises the step: control of the said driveline for activation or deactivation of coasting based on one or several first parameters P 1 and one or several second parameters P 2 for regulation of a temperature T Ex in the said exhaust system; where at least one of the said one or several first parameters P 1 is a first temperature difference between the said first temperature T 1 in the said exhaust system and a reference temperature T Ref , and the said second parameter P 2 is related to a calculated speed and/or a calculated road inclination over the road section ahead for the said motor vehicle. Further, the invention pertains to a computer program, a computer program product, a system and a motor vehicle comprising such a system.
摘要(中):
本发明涉及一种用于通过其动力传动系统的控制来调节机动车辆中的排气流中的温度的方法,其机动车辆包括:包括内燃发动机的传动系,所述内燃机可经由离合器连接到齿轮箱 装置和排气系统,其布置成用于从所述内燃机中除去废气流; 其中所述方法包括以下步骤:基于一个或几个第一参数P1和用于调节所述排气系统中的温度TEx的一个或多个第二参数P2来控制所述传动系统用于启动或停用惯性滑行; 其中所述一个或多个第一参数P1中的至少一个是所述排气系统中的所述第一温度T1与基准温度TRef之间的第一温度差,并且所述第二参数P2与计算出的速度和/或 在所述机动车辆的前方的路段上计算出的路面倾斜度。 此外,本发明涉及包括这种系统的计算机程序,计算机程序产品,系统和机动车辆。
