Definitions
- the invention relates to a method for determining the current nominal idling speed of an engine of a vehicle with an automated clutch, in particular with an electronic clutch management.
- the instantaneous nominal idling speed is determined from a characteristic curve as a function of the engine temperature in methods known from the prior art.
- a corresponding engine temperature sensor is disadvantageously required in order to obtain suitable engine temperature signals. This increases the installation effort for the vehicle.
- the invention is based on the object of proposing a method for determining the current nominal idling speed, which determines the idling speed even without knowing the engine temperature.
- the object is achieved according to the invention in that the instantaneous nominal idling speed is determined by adapting a known nominal idling speed in a specific operating state as a function of the current idling speed.
- a method according to the invention is proposed with which the current nominal idling speed can be adapted from the current idling speed even without knowing the engine temperature. In this way, an additional engine temperature sensor is not required and the additional installation effort can be saved.
- the nominal idling speed of the previous operating state can be used as the starting value and adapted depending on the current idling speed of the present operating state.
- a large number of current nominal idling speeds are determined for different operating states.
- the nominal idling speed when the engine is cold can be used as the first starting value in the iterative determination and can be decremented depending on the current engine speed of the present operating state. It is also possible that a different idle speed is used for the start value. If e.g. B. the vehicle is switched off in the meantime and the engine is not completely cooled when restarting, the nominal idle speed last determined can preferably be used as the starting value.
- the nominal idling speed used as the starting value is decremented when the current idling speed falls below the nominal idling speed by a predetermined amount.
- the current nominal idle speed z. B. in the states neutral and / or starting the transmission for certain operating conditions such as. B. "clutch open", “idle switch actuated” or the like, changed or decremented.
- the method according to the invention can preferably be used in all vehicles with an electronic clutch management (EKM) or with an actuator for controlling an automated clutch (AK), in particular if no CAN bus is provided.
- EKM electronic clutch management
- AK automated clutch
