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.
