Abstract

The invention relates to an electronic control unit for a motor vehicle with a plurality of data networks and an electronic immobilizer. The control unit according to the invention is configured both as a vehicle-end control section for the electronic immobilizer and as a gateway between at least two of the data networks. At least one component of the gateway also serves as a component of the vehicle-end control section for the electronic immobilizer. Preferably, there is common use of components of the gateway for the immobilizer function such that, in addition to the normal vehicle-end immobilizer control section, a further, redundant vehicle-end immobilizer control section, is formed, which significantly reduces the failure rate of the immobilizer.
