Definitions

  • the invention is based on a method for controlling an internal combustion engine of a vehicle, in which the internal combustion engine is switched off or started automatically in certain operating states of the vehicle.
  • a method for starting an internal combustion engine of a motor vehicle is known for example from DE 197 43 492 AI.
  • shift operation the engine is automatically switched off by a control device in the presence of certain operating conditions, such as driving speed, the driver's desired torque and the like, and is automatically restarted.
  • the starting process takes place in such a way that fuel is injected directly in a first injection into the combustion chamber whose associated piston is in the working phase.
  • Such a method makes it possible to carry out a start-stop operation of the internal combustion engine without using electrical starting means or other mechanical or electrical energy stores.
  • the internal combustion engine is restarted solely by igniting a mixture in one of the cylinders.
  • operating parameters such as driving speed, driver's desired torque in the form of an accelerator pedal position, neutral position of the transmission, actuated service brake and the like are used in order to recognize a situation in which the internal combustion engine is to be switched off.
  • the present invention has for its object to prevent the engine from turning off in situations where turning off the engine is undesirable or even dangerous.
  • the aforementioned problem is solved by a method for controlling an internal combustion engine of a vehicle, in which the internal combustion engine is automatically switched off or started in certain operating states of the vehicle, characterized in that information from the braking system is included in the determination of the operating states.
  • the internal combustion engine is not switched off during emergency braking even after the vehicle has come to a standstill. In a dangerous situation it can be important that the vehicle can be accelerated again quickly afterwards. A necessary engine start would lead to an undesired deceleration.
  • the information from the brake system can preferably be taken from a so-called brake assistant.
  • the vehicle parking brake or handbrake can be actuated automatically, for example by the ABS control unit, for example when the driver switches off the vehicle.
  • this method comprises steps that can recognize a stop on a mountain. It is advantageous if the internal combustion engine is not switched off during the stop. This mountain situation can be determined, for example, by an independent position sensor of the vehicle or, for example, by determining the braking holding torque or the like.
  • the internal combustion engine is switched off when a parking brake of the vehicle is actuated. The parking brake is usually only applied when the vehicle is to be stopped for a longer period of time.
  • the information from the brake system contains the requested brake pressure.
  • the information from the brake system can include the time gradient of the requested brake pressure.
  • Emergency braking can be derived from the brake pressure and its gradient. In the event of emergency braking, the internal combustion engine is advantageously not switched off even after the vehicle has come to a standstill, in order to enable the driver to react immediately to the changing situation.
  • the system mentioned at the outset is also implemented by a motor vehicle with an internal combustion engine, a service brake and a control device for controlling the internal combustion engine, the control device being designed in such a way that it can carry out a method according to one of the preceding claims and by a storage medium on which a computer program is stored, which is executable on a control device, in particular for an internal combustion engine, wherein the computer program can control one of the aforementioned methods when it is executed.
  • a method for starting the internal combustion engine is Engine stored in a control unit of the internal combustion engine. This method permits a start-stop operation of the t internal combustion engine, in which a restarting of the internal combustion engine of an ignitable mixture in a cylinder of the internal combustion engine, which is currently in the power stroke takes place solely by injection and ignition 5.
  • the control unit is additionally connected to a control unit for the service brake, for example via a vehicle bus or its own wiring or the like.
  • control unit of the internal combustion engine is connected to further sensors, for example to a sensor on the parking brake.
  • the control unit of the internal combustion engine can now recognize the requirements for "engine off” from various parameters, e.g.ffygeschwindig-
  • the brake assistant is a procedure for the detection of an emergency braking, which consists of different parameters
  • a further procedural step can be provided in which the situation when starting off on a mountain can be recognized.
  • the activation of a parking brake can be used as a signal for switching off the engine. As soon as the parking brake is applied, the engine is switched off.

Abstract

L'invention concerne un procédé de commande d'un moteur à combustion interne d'un véhicule, procédé selon lequel le moteur à combustion interne est arrêté ou démarré de façon automatisée dans certains états de fonctionnement dudit véhicule. Ce procédé se caractérise en ce que l'arrêt du moteur dans des situations où cet arrêt est inopportun voire dangereux est évité du fait que des informations du système de freinage interviennent dans la détermination des états de fonctionnement.
