Abstract
A device for operating an apparatus comprising a first controller configured to be controlled by a first control signal, a second controller configured to be controlled by a second control signal, a control unit operatively connected to the first controller and the second controller, wherein the first controller and the second controller are both configured to operate the apparatus.
Claims20
A method for operating an apparatus of a vehicle comprising:
- generating a control signal by a first controller operating the apparatus in a first operation mode;
- evaluating the control signal by a main controller to provide an evaluation result;
- and
- taking over operating of the apparatus by a second controller according to the evaluation result,
- wherein the second controller is implemented in a diverse architecture with respect to the first controller.
