Schaltungsanordnung zur Aktivierung eines CAN-Bus-Steuergerätes

摘要

The invention relates to a circuit for activating a control unit such as an ABS controller in a vehicle via a CAN (car area network) bus when the ignition is switched off. Said circuit is characterized by having a first input (E1) for a logic activation signal (CAN1RXI) for the control unit, an input filter for suppressing interfering pulses in the activation signal, and a device for generating an output signal (CAN_WU) that activates the control unit when a predeterminable number of activation signals are detected within a predeterminable period of time.
