Definitions

  • the invention relates to a method and a device for controlling an electromagnetic consumer.
  • a method and a device for controlling an electromagnetic consumer are known. Such electromagnetic consumers are used in particular for controlling the metering of fuel in internal combustion engines.
  • a solenoid valve determines the duration of injection and / or the start of injection.
  • solenoid valves In solenoid valves usually passes between the actuation time and the response of the solenoid valve a certain period of time. This period of time is commonly referred to as the switching time of the valve. This switching time depends on various parameters. Such parameters are, for example, the coil voltage and / or the coil temperature and / or the current flowing through the coil.
  • a variable switching time of the solenoid valve in turn has a variable injection duration and / or a variable start of injection and thus an undesirably changing amount of injected fuel result.
  • the DE 40 20 094 describes a method and a device for controlling an electromagnetic consumer. This device is based on the task of safely closing the solenoid valve and terminating the injection when an error occurs. For this purpose, the voltage applied to the switching means, which corresponds to the extinguishing voltage, monitored. Upon detection of a fault, the control of the solenoid valve is terminated. It is provided that the solenoid valve is driven so long that a certain amount of fuel is still metered, so that emergency operation is possible. When switching off the solenoid valve, a high voltage is induced at this, which is limited by the extinguishing device to a certain value. It is checked whether this voltage increase occurs. For this purpose, the voltage at a point B is compared with a reference value. If the voltage at the point B exceeds the reference value, a signal is generated. If this is the case, then the device works properly. If this is not the case, then errors are detected. That is, based on the period during which the erase voltage is applied is detected on error.

  • the time is determined at which the erase voltage drops below a threshold value (TS).

  • the duration of the erase voltage then corresponds to the time interval between the switching off of the consumer and the falling below the threshold value.
  • a switch-on time in the specification of the beginning and the switch-off time in the specification of the duration of the control is taken into account. Instead of the duration of the control and the end of the control can be specified. When setting the end, the switch-on time and the switch-off time must be taken into account.

  • the current I flowing through the load 100 generates a voltage drop at the current measuring resistor 120 which is detected by the current detection 125. Starting from the voltage drop, the current detection determines the current value I and writes this into the register 126. The switching time determination 152 reads the current value I from the SPI register and determines, based on the current value I, the switching times TA. The switching times TA are taken into account by the drive timing 154 in the determination of the drive signal T.
