Device for prompting a controller

摘要

A device for prompting a controller in a vehicle to switch the controller from a normal operating state into an idle state includes a prompting device which switches a power supply through to the controller when activated to bring it into the normal operating state. The prompting device is connected in series to a first condenser and a resistor between power supply lines. A central tap between the first condenser and the resistor is connected directly or indirectly with the control input of a first transistor. An output of the first transistor is connected directly or indirectly with a control input of a second transistor that switches the supply current for the controller to be prompted. A connection line led back from the second transistor to the node between central tap and control input of the first transistor.
