  • EU to reduce C0 2 emissions, in many market segments through the so-called start / stop function.
  • various operating strategies for requesting start and stop in start / stop operation by the driver are known.
  • Document DE 10 2009 045 409 A1 describes a method and a device for the automatic restart of a combustion engine with an automatic start-stop function that is switched off a second time.
  • the restart is made possible by the fact that, if within a preset period of time before any actuation of the clutch, the brake has been applied, the engine is not started until the clutch is complete and the brake is not applied.
  • From the document DE 10 2010 003 673 A1 a method for operating a vehicle, for which a free running operation is provided between a transmission and a drive motor, in which when operating an accelerator pedal after the freewheeling operation provided a gear recommendation and a current speed of the drive torque to a recommended speed is increased, which corresponds to the gear recommendation in a current speed situation of the vehicle.
  • Stop-in-Neutral a stop of the motor is triggered when all necessary start / stop Releases or no start / stop prohibitions, eg idle phase requested by diagnoses or tank ventilation, speed threshold not fallen below, present and the driver first enters the clutch, the gear lever in the "neutral" position, which corresponds to the idle position, bring and release the clutch.
  • the engine start may be initiated by start-up requirements of the system, for example when the catalyst temperature is below a predetermined threshold, the state of charge of the battery is below a threshold, the air conditioning is on, etc., independently of the driver, which is an automatic start , Alternatively, when the driver wishes to continue, the engine is restarted by pressing the clutch pedal. The driver then has to insert the gear.
  • Another operating strategy with manual switches turns off the engine when the vehicle is below a speed threshold and the driver simultaneously holds the clutch and presses the brake. This corresponds to rolling out at a red traffic light.
  • This operating strategy is referred to as "stop-in-gear" (SiG), as it can remain engaged in this gear. As soon as the driver releases the brake, the engine is restarted, possibly independent of system startup requirements.
  • the advantage of this operating strategy is the development of additional fuel savings, especially in the NEDC.
  • the times when the clutch has to be stepped on are exactly defined.
  • the use of the brake pedal is free.
  • SiN is five seconds before starting the Engine already started by pedaling the clutch.
  • SiG the engine is only started when the vehicle is to start, ie the brake is released.
  • Triggering the engine when the brake is released may result in unintentional rolling back of the vehicle on a slope or idling on the vehicle

  • HHC is not necessarily necessary in the presented process.
  • a stop of the engine even in extreme mountain driving situations must not be generally prohibited, since the vehicle in extreme hill-climbing situations, namely when a threshold is exceeded, only with the handbrake before rolling or rolling back must be secured before an engine stop is allowed.
  • This can be achieved, in particular, by incorporating the signal, for example, of the conventional handbrake (handbrake securely tightened) or the foot parking brake (active).
