Definitions

  • the invention relates to a method for operating a fuel pump according to the preamble of claim 1 or 4.
  • a fuel pump of a motor vehicle which serves to deliver fuel toward an internal combustion engine of the motor vehicle, has an EC electric motor to drive the fuel pump.
  • a fuel pump is driven in such a way by the EC electric motor of the same that for the promotion of fuel in the direction of the internal combustion engine of the energized EC electric motor drives the fuel pump in a defined direction of rotation.
  • the EC electric motor of the fuel pump is switched off to switch off the motor vehicle or its internal combustion engine.
  • fuel pumps of the EC electric motor of the fuel pump is turned off such that a rotor of the EC electric motor due to its moment of inertia runs undefined and stops in any relative position to the stator of the EC electric motor.
  • a subsequent starting of the internal combustion engine must then be carried out in advance synchronization between the rotor and the stator of the EC electric motor, so that a certain time elapses until a required for the start of the engine to be performed first ignition amount of fuel and a required fuel pressure are provided can.
  • the time required to synchronize the rotor and stator of the EC electric motor is considered disadvantageous.
  • the present invention based on the problem to provide a novel method for operating a fuel pump.
  • this problem is solved by a method according to claim 1. After that, when no more fuel is needed, the EC electric motor of the fuel pump is turned off such that a rotor of the EC electric motor expires defined, so that after the run of the EC electric motor assumes a defined relative position to the stator of the EC electric motor ,
  • this problem is solved by a method according to claim 4. Thereafter, when no more fuel is needed, the EC electric motor of the fuel pump is turned off such that a rotor of the EC electric motor runs undefined, then at least one pair of coils of the stator of the EC electric motor is energized so that the rotor of the EC -Electric motor occupies a defined relative position to the stator of the EC electric motor.
  • Both aspects of the present invention have in common that for the first ignition when starting an internal combustion engine, the required amount of fuel and the required fuel pressure can be provided within a very short time.
  • the EC electric motor of the fuel pump is turned off such that the rotor of the same expires defined, so that the same assumes a defined relative position to the stator of the EC electric motor after running out.
  • the rotor of the EC electric motor runs undefined, after the leakage, however, at least one pair of coils of the stator of the EC electric motor is energized so that the rotor of the EC electric motor thereof transferred to the defined relative position to the stator becomes.
  • the necessary amount of fuel and the required fuel pressure can be provided within a very short time for the first ignition.
  • the present invention relates to a method for operating a fuel pump of a motor vehicle.
  • a fuel pump is driven by an electric motor.
  • the operation of the fuel pump via the electric motor for conveying fuel toward an internal combustion engine is in Fig. 1 visualized by a block 10.
  • the fuel pump is driven by an EC electric motor.
  • a subsequent block 11 it is checked whether fuel is still needed. Then, when it is determined in the subsequent block 11 that fuel is no longer needed, the system branches to block 12 and the EC electric motor of the fuel pump is turned off in block 12. If, on the other hand, it is determined in block 11 that fuel is still needed, branching back to block 10 takes place.
  • the rotating magnetic field of the stator is changed such that a speed of the rotor is preferably continuously reduced, and the rotor stops in the defined relative position to the stator of the EC electric motor.
  • This change in the magnetic field of the stator takes over the control unit of the EC electric motor.
  • the rotating magnetic field of the stator of the EC electric motor is stopped in a defined angular position, so that the rotor of the EC electric motor stops in the defined relative position to the stand.
  • the inventive method according to the first aspect of the present invention finds particular use when the fuel pump is operated by an EC electric motor with integrated position sensor.
  • the EC electric motor of the fuel pump in block 13 is turned off such that the rotor first runs undefined, wherein then in block 14 at least one coil pair of the stator is energized such that the rotor is transferred to a defined relative position to the stator of the EC electric motor and occupies this relative position. If, on the other hand, it is determined in block 11 that fuel is still needed, then in accordance with the signal flow diagram of FIG Fig. 1 back to block 10 and the fuel pump continues to be driven by the EC electric motor.
  • the transfer of the rotor into a defined relative position to the stator of the EC electric motor according to block 14 can take place either immediately following the undefined running out of the rotor or immediately before a subsequently to be executed engine start.
  • the corresponding current supply of the electric motor is preferably triggered by unlocking a motor vehicle locking system.
  • the fuel pump namely the EC electric motor of the same operate in a low speed range, so as to fill the fuel system of the motor vehicle and build up a defined fuel pressure before the actual start of the engine.
  • This can cause noise the fuel pump can be reduced when the internal combustion engine is not running.
  • the fuel pressure required for the first ignition and the required amount of fuel can be provided even faster.
  • the position of the fuel pump namely the relative position between the stator and the rotor of the EC electric motor of the fuel pump, is known, so that no synchronization between stator and rotor must be performed.
  • the starting time of the internal combustion engine can be reduced because the fuel pressure required for the first ignition and the required fuel quantity can be provided within a very short time.
