Abstract
The present invention describes a circuit for activating a control unit such as an ABS controller in a vehicle by way of a CAN bus, with the ignition turned off, which is in particular characterized by a first input for a logic activation signal for the control unit, an input filter for suppressing disturbing pulses in the activation signal, and a device for producing an output signal (CAN_WU) that activates the control unit when a predeterminable number of activation signals is recorded within a predeterminable duration.
