ELECTRONIC CONTROL DEVICE AND METHOD FOR CONTROLLING THE OPERATION OF MOTOR VEHICLE COMPONENTS

摘要

According to the invention, operation voltage is monitored in a microcontroller (12) having associated output stages (14-1, 14-2) which are used to control components. In the case of over voltage, the output stage (14-1, 14-2) is disconnected. Two technology-related, voltage monitoring devices (22, 24) working in different operation voltage areas, are provided. Due to the combination thereof, a highly precise disconnection threshold and a greater area for the operation voltage, which is to be monitored, can be obtained. If a malfunction of an overvoltage occurs, the output stages (14-1, 14-2) can be disconnected in a reliable manner.
