Embodiment Construction

[0019] like figure 2 and image 3 As shown, unnecessary start activations are suppressed by introducing a so-called brake-start indicator. The brake start flag is, for example, one bit, and the bit is "yes", "true" or "1" when the flag is set, and "no", "not" or "zero" when the flag is not set.

[0020] While driving in a car with a manual transmission, the figure 2 The routine program shown in , wherein, in step S1, first set the brake activation flag to "No".

[0021] In step S2, it will be checked whether the following four conditions can be met simultaneously: the internal combustion engine is stopped, for example as figure 1 Results of the parking routine shown on the left; transmission in neutral; brake pedal depressed or applied; clutch pedal released or not depressed. If these four conditions cannot be satisfied at the same time, step S2 is re-executed. If these four conditions are met simultaneously, a timer is started in step S3, that is, a time counter is sta...

Abstract

The invention relates to a method of automatically restarting an internal combustion engine of an automobile with a manual speed changer during the short-time stop thereof based on the current operation state of a clutch and a brake of the automobile.According to the invention, a comfortable and oil-saving restarting of the automobile can be realized in such a way that the brake is actuated within a pre-set period before any operation of the clutch.The internal combustion engine is started when the clutch is fully actuated and the brake (S10) is not actuated.

Description

Technical field [0001] According to the preamble of the independent claim, the invention relates to a method for restarting a briefly stalled internal combustion engine in a vehicle with a manual transmission on the basis of the current operating states of the clutch and brake and a corresponding start-stop system. control device. Background technique [0002] In so-called micro-hybrid vehicles with a start-stop function, that is, hybrid gasoline-electric vehicles, the internal combustion engine can be automatically stopped or shut down when traction power is not required (for example, when waiting at a traffic light), and the internal combustion engine can be automatically stopped when the driver requests traction power again. Restart the internal combustion engine. This start-stop working method reduces fuel consumption and reduces noise pollution. Systems that make this type of start-stop operation possible are, for example, belt-driven integrated starter / generators (be...
