Definitions
- the invention is based on a control system for the electric fuel pump of an internal combustion engine according to the preamble of claim 1.
- a circuit arrangement for the control of a fuel pump in an internal combustion engine is known in which the power supply is below a minimum engine speed to the fuel pump is switched off.
- the invention specified there can be guided by the consideration that, when the ignition is switched on, the speed of an internal combustion engine only drops below minimum values if the machine is braked by external influences, especially in the event of an accident. In this case, the delivery of fuel from the tank towards the internal combustion engine should then be interrupted for safety reasons.
- DE-Offenlegungsschriften in the DE-Offenlegungsschriften
- the object of the invention is therefore to develop and provide a safe and reliable shutdown concept. This task is solved with the features of the main claim.
- the exemplary embodiment relates to a control system for the electric fuel pump of an internal combustion engine.
- the electric motor of the fuel pump not shown, is designated by 10. It receives its supply voltage U Batt from a
- 13 denotes a first sensor for a first speed, 14 a second sensor for a second speed.
- sensor 13 is assigned to the crankshaft of the internal combustion engine, sensor 14 to the camshaft.
- the two sensors 13 and 14 are connected to a block 15, in which a threshold value query 16a and 16b for each of the signals from the two sensors 13 and 14 and an AND gate 17 for the output signals of the threshold value query are symbolically shown.
- This AND gate 17 in turn controls the switch 11 between the power supply line 12 and the electric motor 10 of the fuel pump.
- Block 15 is additionally connected to the power supply line 12 via a supply voltage connection 19.
- the basic idea of the present invention is to open the switch 11 in series with the electric motor 10 of the fuel pump depending on the speed only when both the signal from the sensor 13 and the signal from the sensor 14 have a minimum value. In this way it is ensured that the motor vehicle still remains drivable if one of the two sensors 13 or 14 fails.
- the AND gate 17 shown in block 15 takes over in connection with the preceding threshold value queries a known plausibility query of the two signals from the sensors 13 and 14 and only when these two signals are plausible to each other and both speed values fall below a selectable lower value , the switch 11 is also opened.
- the two sensors 13 and 14 are assigned to different shafts of the internal combustion engine, i.e. Sensor 13 e.g. the crankshaft and sensor 14 e.g. the camshaft.
- Sensor 13 e.g. the crankshaft
- sensor 14 e.g. the camshaft.
- the plausibility check of the two output signals of the two sensors 13 and 14 must be
- crankshaft speed and camshaft speed into account.
- care must be taken to ensure that the fuel pump can also deliver fuel at the start of a starting process.
- means are provided which make the plausibility check ineffective at least during phases of the starting process.
- control system in addition to switching off the fuel pump at low speeds, can also be used as an overspeed protection for the internal combustion engine, in that the power supply to the fuel pump is interrupted when speeds critical to safety are exceeded. In this case too, the system can respond when the plausibility check of both values of sensors 13 and 14 results in a safety-critical speed being exceeded.
