Definitions

  • the present invention relates to an operating method and a control unit for an active oil separator, in particular in connection with the ventilation of a crankcase of a drive of a working device, a vehicle and/or a motor vehicle, an active oil separator as such and a working device, in particular a vehicle or motor vehicle.
  • crankcase In many work devices and in particular in vehicles and motor vehicles, drives are used in addition to other units, which also have a crankcase, among other things. Due to the limited tightness of the crankcase, portions of a lubricant used can get into the intake air duct of the engine and/or into the atmosphere during operation in connection with blow-by or leakage gas flows. In order to reduce the proportion of the lubricant released into the intake air duct of the engine or into the atmosphere, oil separators are operated in connection with ventilation of the crankcase. Commonly used oil separators are either of a passive nature, e.g. in the sense of a cyclone principle, or, if they are of an active nature, e.g.
  • centrifugal separator for cleaning a crankcase gas generated by an internal combustion engine is known.

At least one element of the rotor is like this stored that it is axially displaceable from a first rest position to a second operating position by means of an actuator element.
  • the invention is based on the object of specifying an operating method for an active oil separator, a corresponding control unit, an oil separator as such and a working device in which the operation of the active oil separator can be adapted to the operation of the higher-level working device using particularly simple means.
  • an operating method for an active oil separator is created, in particular in connection with the venting of a crankcase of a drive of a working device and/or a motor vehicle.
  • a rotary element of the oil separator and in particular a rotary plate of a plate separator is rotated at a specific speed for an oil separation process.
  • the specific speed is controlled and/or regulated according to the invention (a) depending on an operating state of at least one unit of the working device and/or (b) depending on an operating state of at least one component of the active oil separator itself.
  • a particularly high degree of flexibility is achieved with the operating method according to the invention when a target operating mode is a mode from the group of modes which include normal operation, acoustically optimized operation, MSA stop operation, in which the active oil separator is activated when the internal combustion engine is switched off Drive is operated above a certain minimum speed and at a speed sufficient for component protection and has a diagnostic mode.
  • a target operating mode is a mode from the group of modes which include normal operation, acoustically optimized operation, MSA stop operation, in which the active oil separator is activated when the internal combustion engine is switched off Drive is operated above a certain minimum speed and at a speed sufficient for component protection and has a diagnostic mode.
  • the mode for acoustically optimized operation defines an operating mode with a speed below a specific maximum speed, an injection quantity for the fuel in the internal combustion engine below a maximum injection quantity, a maximum speed of the vehicle and possibly other parameter conditions.
  • the active oil separator is generally operated with the lowest possible but still sufficient degree of separation. This corresponds to the lowest possible but sufficient speed for an oil separator with a rotary element, eg a disc separator. This low retention rate or Speed should also be reached as quickly as possible in order to avoid acoustic abnormalities.
  • the MSA stop coasting mode defines an operating mode in which, despite the combustion engine being switched off, the active oil separator is operated above a certain minimum speed and at a speed sufficient to protect the components.
  • the active oil separator In normal operation, the active oil separator should be operated with a separation rate or speed that represents the best compromise between drive power and degree of separation.
  • the separation rate or speed is optimally selected depending on the injection quantity, engine speed of the internal combustion engine, the temperature of the engine oil and/or the temperature of the active oil separator.

  • a setpoint filtering unit is configured, which is set up to receive one or more values for a control value and/or for a setpoint speed as a specific speed for the rotary element of the active oil separator or data characteristic of it and, in particular on the Based on a respective target operating mode and/or recorded data, signals and/or measured values for an operating state of the at least one unit of the working device and/or the at least one component of the active oil separator, in cooperation with and/or at the instigation of the operations coordinator unit and/or the setpoint value creation unit , to filter and to provide one or more filtered values for a setpoint speed.
  • the reference value filtering unit enables filtering by means of different low-pass filters and, in particular, depending on the selected operating mode.
  • the setpoint generation unit enables different filter constants for the rising and falling edges of a setpoint to be filtered. This makes it possible for high setpoint values to be approached as quickly as possible and low setpoint values to be approached more slowly during normal operation. This means that the active oil separator can be operated with a lower setpoint variation.
  • the diagnostic mode also enables independent filter constants.
  • a diagnostic function unit can be configured, which is set up to diagnose the functional integrity of the active oil separator and/or to generate one or more values for a setpoint speed as a specific speed for the rotating element of the active oil separator or data characteristic of it to be determined, obtained and/or provided for diagnostic operation of the active oil separator.
