Abstract: A sensor arrangement includes at least one sensor which is connected to a first control unit and a second control unit. The at least one sensor has two sensor connections, and each of the sensor connections of the at least one sensor is electrically connected to an assigned node. Each node is respectively connected downstream of a control unit input of the first control unit and respectively connected upstream of a control unit input of the second control unit.

Abstract: An operating method is for a redundant sensor arrangement of a vehicle system. The sensor arrangement includes two controllers and multiple sensors. Individual sensors of the multiple sensors, in a normal mode of the vehicle system, are each coupled to a controller embodied as a primary controller and, in an emergency mode of the vehicle system, are each coupled to a controller embodied as a secondary controller and are supplied with power. The corresponding controller coupled to the sensors receives and evaluates signals from the individual sensors. Initialization of the sensor arrangement involves an operating voltage being applied to both controllers and a check on the sensor arrangement being performed. The sensors, in a first checking step, are coupled to a first controller and are checked by the latter and decoupled from a second controller, and the first controller subsequently hands over the sensors to the second controller.

Abstract: An operating method for a redundant sensor arrangement of a vehicle system including a primary controller, a secondary controller and multiple sensors, wherein the individual sensors, in a normal mode of the vehicle system, are each coupled to the primary controller and, in an emergency mode of the vehicle system, are each coupled to the secondary controller and are supplied with power, wherein the controller that is coupled to the sensors receives and evaluates signals from the individual sensors, includes applying an operating voltage to both controllers and coupling the sensors to the primary controller and checking the coupled sensors with the primary controller. The secondary controller, in the decoupled state, checks its internal voltage supply and at least one internal signal path. Then, the secondary controller is connected to the sensors to checking their power supply. The system initialization is concluded when no errors have occurred.

Abstract: A method for determining a slope of a roadway on which a vehicle is located includes imputing image data, supplied by an image sensor, pertaining to surroundings of the vehicle, identifying a defined reference object in the surroundings of the vehicle using the image data, determining an angle relationship between the reference object and the surroundings, estimating a slope of the roadway with reference to the determined angle relationship, and generating a signal indicative of the slope of the roadway. A device for determining a slope of a roadway on which a vehicle is located is configured to execute such a method.

Abstract: A method for determining an incline of a road on which a vehicle is located includes importing image data of an environment of the vehicle, the image data being generated by an image sensor. The method further includes identifying a defined reference object in the environment of the vehicle from the image data and identifying a relationship between the identified reference object and a defined reference system of the image sensor. The method also includes estimating the incline of the road on the basis of the identified relationship and providing a signal representing the incline of the road.
