Definitions

  • the invention relates to a device for monitoring a starting device according to the preamble of claim 1.
  • the start request of the Driver usually by closing an electrical contact, for example a switch communicated to the starting device.
  • an electrical contact for example a switch communicated to the starting device.
  • a device known that only enable starting if, for example, the Clutch pedal is depressed In this context and further The environment is referred to WO 94/15808 and JP 09042005 A. In these Publications describe devices that are unintended Prevent driving away by only starting certain engines Vehicle operating conditions, such as operating a clutch pedal, allow.
  • the present invention is in contrast to a newer type of starting devices aimed for motor vehicles.
  • electrical machines are used both as starters and operated as a generator.
  • This electrical Machines are connected via an inverter to a power grid connected, to which consumers and batteries are connected are.
  • An electrical valve train for example, can serve as a consumer be provided, which is operated reliably during the starting process must become. With such an electric valve train, but also with others Consumers must have sufficient electrical energy already at Be ensured.
  • a control unit used which at certain time intervals not even with one vehicle in operation can be activated and the electrical state of the electrical system checked. With such an automatic activation the control unit must be completely excluded, that the electrical machine also serving as the starter is unintentionally is operated and, for example, with the gear engaged, the vehicle in Movement sets.
  • the object of the present invention is therefore a device of the beginning mentioned type to the extent that such an unintentional Movement is excluded.
  • an additional control is provided that the inverter activated or deactivated depending on vehicle operating information.
  • the link between the vehicle operating information and the The inverter can be enabled or disabled using software. Most security, however, brings a hardware circuit in the form of a Driver.
  • the inverter which is the connection between the vehicle electrical system and the electrical machine, is only activated, if the vehicle operating information permits.
  • a speed signal can preferably be used as vehicle operating information of the engine and a clutch actuation signal can be used.
  • the additional control is designed such that the inverter is only set to active when either the clutch is actuated or the speed exceeds a certain value. With this configuration it is ensured that the electrical Only start the machine when the clutch pedal is depressed can. In addition, continued operation of the electrical machine is also without Clutch actuation possible when a certain engine speed has been reached or exceeded.
  • Fig. 1 is a starting device with a control unit in a schematic manner 10, which shows an inverter 14, a DC / DC converter 22, a central unit 30 and an additional controller 40.
  • the inverter 14 is connected to an asynchronous motor 12 which can be operated both as a starter and as a generator.
  • the of the asynchronous machine 12 in the generator mode current supplied or of this current required in starter mode is supplied via the inverter 14 converted into a direct current and fed into an electrical system or taken from this.
  • the vehicle electrical system consists of a power supply unit 16 with a Mains voltage of 42 V, which is connected directly to a 36 V battery 20 as well as to a Consumers are concerned.
  • this consumer is an electrical one Valve train 18.
  • a 12 V electrical system 24 is provided, that of the 42 V electrical system is supplied via the DC / DC converter 22. There are 24 on the 12 V electrical system in the present case a 12 V battery 26 and other consumers 28 are connected.
  • the central unit 30 and the electronic unit are connected via a local CAN bus 34 Valve train 18 connected to digital engine electronics DME 36.
  • the digital engine electronics 36 is also with a further CAN bus system in connection and also receives signals from terminal 50 and one Diagnostic management.
  • the central processing unit 30 receives its commands from the digital motor electronics 36. In addition, information is read in via the CAN bus 32. Further input information of the central processing unit 30 is a wake-up signal W, a charge signal L, a voltage signal from the 36 V battery U 36V and a temperature signal from the 36 V battery T 36V .
  • the central controller 30 acts on the inverter 14, more precisely one Driver circuit 15 of the inverter 14 and causes one accordingly operation of the asynchronous machine as required by the input variables 12th
  • the central control 30 is not activated even in the case of one temporarily activated (woken) vehicle in operation.
  • the wake-up signal can also be within the central controller 30 to be generated.
  • the central processing unit 30 now also checks when the computer is switched off Vehicle the 42 V vehicle electrical system voltage at certain intervals, to recognize whether the power / voltage required for a starting case can also be provided by the 36 V battery 20 can. If this is not the case, the 36 V battery 20 becomes the 12 V battery 26 loaded via the DC / DC converter 22.
  • a separate controller 40 is provided, which as the input signal Speed signal n of the engine and a clutch signal KS receives.
  • the controller 40 generates a signal and these input variables sends this to the driver circuit 15 of the inverter 14, which thereby being put into an active or a deactivated state.
  • FIG Block diagram shown in Fig. 2.
  • this is Speed signal n of the motor into a frequency-voltage converter Voltage converted.
  • This voltage is applied to a threshold comparator 52 applied, which then generates a signal when the voltage U exceeds a predetermined value.
  • the resulting signal is converted into a 0/1 information in a unit 54 and an AND Gate 58 passed.
  • the unit 56 converts in accordance with the actuation of the Coupling switch KS the signal applied to it also in a logical 0/1 signal and also passes this on to the AND gate 58.
  • the electrical machine can be operated upon automatic activation of the central processing unit 30 effectively avoided by the alarm signal W.
  • An actuation of the asynchronous machine 12 from a standing position can thus only be activated when the Coupling switch done. Only when the engine speed then a certain The asynchronous machine can also exceed the threshold value continue to be operated without actuating the clutch switch.
