Embodiment Construction

[0033] figure 1 A schematic flow chart of a method according to the invention for assisting a driver of a motor vehicle in using an automatic engine start-stop control device of a motor vehicle is shown. The method comprises the following steps: In a first step 101, at least one running time t of the vehicle is detected and saved B , and for the engine start-stop automatic control device at the running time t B Each of the total number P of engine stop processes performed within , at least detects and saves its respective duration t MS,k , where k=0,1,2,…P, and P∈[0,1,2,…]. In a second step 102, determine and run time t B and the total duration t MS,k The first proportional value related to W 1 :

[0034] (1) W 1 = Σ k = 0 P t MS ...

Abstract

The invention relates to a method and a device for supporting a driver of a motor vehicle in utilizing an automatic engine start-stop system of the motor vehicle. The method includes the steps of firstly, (101) registering and storing, for at least one operating time tB of the motor vehicle and for each engine stop of a total number P initiated by the automatic engine start-stop system in the operating time tB, at least the respective time durations tMS, wherein k=0, 1, 2, . . . P and P belongs to [0, 1, 2, . . . ]; Secondly, (102), determining a first ratio value W1 that is dependent on the operating time and the added time durations; and thirdly, (103), generating and outputting the first ratio value and / or an output which is dependent on the first ratio value.

Description

technical field [0001] The invention relates to a method and a device for assisting a driver of a vehicle in using an automatic engine start-stop control device. The invention also relates to a motor vehicle with such a device. Background technique [0002] An automatic engine start-stop control device is an automatically working system for reducing the fuel consumption of a vehicle during stationary phases (such as when stopped at a red light). When the neutral gear is engaged and the clutch of the car is released, the automatic engine start and stop control device performs an automatic engine stop process. If the clutch pedal is operated again, the automatic engine start-stop control device performs an automatic engine start process. The automatic engine start and stop control device usually only performs the engine stop process under certain preset conditions: only when some temperature regulations are met (engine, outside temperature is within a certain range, for exam...
