Electronic control device for vehicle components has a microcontroller to produce control signal, final stage to activate and deactivate components and monitoring device

摘要

The electronic control device includes a microcontroller (12) with end stages (14-1, 14-2). The voltage is monitored, and in the event of excessive voltage, even the end stages are switched off. There are two monitoring devices (22, 24) to provide more reliability, precision and versatility. If one of these is unserviceable, the other will remain in operation.
