Embodiment Construction

[0038] figure 1 Five different driving strategies are shown, according to the present invention, a motor vehicle can operate according to this strategy, and the drive system of the motor vehicle can be started accordingly. In the figure, the current speed of the motor vehicle is plotted at the top. The different strategies 1 to 5 are shown on the right, indicated by the numbers above the corresponding columns.

[0039] In all driving strategies, at speeds below v 1 Drive the drive system in a static mode (SSS, "static start and stop"), especially in a static state. The static mode is defined as the frictional engagement interruption of the drive train; in the case of an automatic transmission with a torque converter, the frictional engagement can be closed by the torque converter. In the stationary mode, the internal combustion engine used to drive the motor vehicle is stopped; the starter of the internal combustion engine can be disconnected from the internal combustion engine ...

Abstract

In a method for operating a motor car with a driving engine, the driving engine is an internal combustion engine. The method involves detecting the traveling speed of vehicle and an operation of a speed control unit. The driving mode is automatically selected. The sail mode above the minimum speed of the sailing mode during non-operation state of the speed control unit is selected. The roll mode above the maximum speed of sailing mode, during non-operation state of the speed control unit is selected. The invention also relates to a driving system of the motor car.

Description

Technical field [0001] The invention relates to a method of operating a motor vehicle with a drive engine implemented as an internal combustion engine. The invention also relates to a drive system of such a motor vehicle. Background technique [0002] The driving engine of a motor vehicle mainly plays a role of generating driving force, which is transmitted to at least one driving wheel to generate the moving force of the motor vehicle. The driving engine is embodied here as an internal combustion engine, such as a spark ignition engine or a diesel engine. Since the internal combustion engine already consumes fuel when running without generating driving force, various methods have been proposed to reduce fuel consumption under driving conditions where driving force is not required. [0003] Therefore, it is known from, for example, WO 2010 / 121861A1 that the vehicle is operated according to the result of the authenticity check of the automatic speed control function or the adaptive...
