Definitions

  • the present invention relates to a method for controlling and / or monitoring functions by means of sensors in a region supplied by a power supply, in particular in a vehicle supplied with an on-board voltage.
  • Certain components in vehicles such as the alarm system, interior lighting or the sill trim, are activated when required with a wake-up signal from hibernation. This is important in order to avoid a high power consumption of the components in the vehicle standstill and thus the discharge of the vehicle battery.
  • DE 103 30 451 B3 describes a device which generates such a wake-up signal. Thus, for example in vehicles, all networked ECUs can be "awakened”.
  • the object of the present invention is the simple and cost-effective generation of a wake-up signal, even for non-networked control devices or sensors.
  • the object is achieved according to the invention in that a signal is supplied to the sensor when the current and / or the voltage of the power network is changed.
  • the invention can use the on-board voltage of all vehicles, such as vehicles, trucks, ships, aircraft, helicopters, two-wheelers, agricultural and working machines.
  • the use of the invention for all types of bus systems in conjunction with a mains voltage for.
  • a mains voltage for.
  • the characteristic on-board voltage of a vehicle depends on the battery voltage, the engine operation and the active consumers. Therefore, based on the characteristic on-board voltage changes of the on-board voltage can be defined for which the occurrence of the event to be detected is likely.
  • the senor sends a signal to the control unit of the non-networked controller and the function is executed. After the occurrence of the event, the sensor preferably remains active for a follow-up time and then, if no other event occurs, goes to sleep.
  • Figure 1 is a characteristic of a characteristic on-board voltage
  • Figure 2 is a connection diagram of a controller
  • FIG. 3 is a flowchart "illuminated door sill"
  • FIG. 4 shows another embodiment of a flowchart "illuminated door sill"
  • FIG. 5 shows another embodiment of a flowchart "illuminated door sill".
  • FIG. 1 shows an on-board voltage 1 of a vehicle relative to a time axis 2. From an increase and decrease of a characteristic curve 3, it is possible to conclude certain operating states 4, 5, 6, 7, 8 of the vehicle. At the beginning of 4 is the vehicle, there are no consumers active. The first waste 5 shows e.g. starting the engine. Then follows the rise to 14 V, the engine is running, the characteristic area 6 is constant. The shutdown of the engine is shown in the waste 7 of the characteristic curve 3 to 12 V. The next lower drop 8 shows in this situation that the lock is active. Because of this characteristic curve 3, changes in the on-board voltages 1 can be defined.
  • the controller 9 shown in FIG. 2 generates from the input signals
  • the method is described using the example automobile with a retrofitted illuminated door sill, in FIGS. 3-5 for different situations.
  • the door sill should be illuminated.
  • the state "door open” or “door closed” is determined by a sensor, e.g. Reed switch, captured.
  • Wake-up controller 9 detects the on-board voltage 1 "engine running”, generates a wake-up signal 11 and activates the sensor for the duration of the change of the on-board voltage 1 plus, if applicable, the follow-up time. Now the event “Door is opened” comes in. The sensor detects "door open”, the control unit of the sill rail is activated, the sill rail lights up.
  • the procedure for the starting situation "engine running” is described in FIG. 5.
  • the sensor is active, now the event “engine is stopped” occurs.
  • the wake-up controller 9 detects the change in the on-board voltage 1 and holds the Sensor for an after-run time “X” active Now the event “Door is opened” is activated.
  • the sensor detects "door open” and controls the sill rail.The sill lights.After the occurrence of the event "door closed”, the controller keeps the sensor active for an after-run time "X” and then goes into hibernation mode.
