Abstract
The safety device, especially in an electronic motor vehicle control system, protects external circuit branches supplied with current from an engine/motor vehicle control unit so that a single short circuit results in failure of only that circuit branch in which the short circuit is located, so that an emergency operation of the electronic motor vehicle control system is possible. The respective reference grounds of the external circuit branches are connected to a common ground conductor (11) via an interface (3) including respective reference ground connectors (d, k, m). Each reference ground connector includes a safety device in the form of thin wire plug bonds, whose maximum current load sets the maximum current load of the respective external circuit branches. Then, if there is a short circuit to the reference ground of the concerned external circuit branch to a main supply voltage, the remaining circuit branches remain unaffected and operational.
