Problems solved by technology

[0004] However, these start-stop automatic control devices may also switch off the internal combustion engine when it is not desired to switch off the internal combustion engine, especially when the vehicle is parked for such a short period of time that the subsequent start of the internal combustion engine results in a significant delay, or due to switching off and Disturbances from restarting, especially vibrations, noise, etc., especially when the fuel-saving advantages are not desired subjectively or for the individual driver
[0005] Therefore, it may not be desirable to automatically switch off the vehicle in the case of a stop sign or a priority sign, a so-called all-way stop (All-Way Stop), etc.

Embodiment Construction

[0053] figure 1 Shows a part of a car with an internal combustion engine 1, an electrical circuit with a clutch and a transmission 2 coupled to it, a front side camera 3, a sensor 4 for detecting the state of the brakes and electrical circuit or clutch and transmission 2 of the car , GPS and / or communication system 5 and a controller 6 for controlling the internal combustion engine, the controller 6 has an automatic start-stop control device, if a predetermined shutdown condition is detected by means of the sensor 4, the automatic start-stop control device commands the shutdown Pre-determined cut-off conditions include disengaging the clutch, shifting gears to neutral and / or braking.

[0054] Controller 6 executes the following reference figure 2 The described method for selectively shutting down the internal combustion engine 1 according to an exemplary embodiment of the invention is, or is configured for, this.

[0055] In step S10 , the traffic situation of the motor veh...

Abstract

The invention relates to a method for the selective deactivation of a motor vehicle, especially the internal combustion engine of of a motor vehicle by an automatic start-stop device, comprising detecting (S10) a traffic situation of the motor vehicle; and preventing or delaying the deactivation in the case that the detected traffic situation corresponds to at least one predetermined traffic situation.

Description

technical field [0001] The present invention relates to a method and a controller for selectively shutting off an internal combustion engine of a motor vehicle, especially a passenger car, with the controller, a motor vehicle, in particular a passenger car, and a method for executing the Method computer program product. Background technique [0002] A motor vehicle with a stop-start control, also known as a stop-start control or system, is known, for example, from DE 10 2014 108 412 A1. [0003] It is thus advantageously possible to wait at a red light, etc. by automatically switching off the internal combustion engine of the vehicle when predetermined switch-off conditions are detected, such as disengaging the clutch, shifting into neutral gear and braking. to save fuel. [0004] However, these start-stop automatic control devices may also switch off the internal combustion engine when it is not desired to switch off the internal combustion engine, especially when the veh...
