Operating method for a redundant sensor arrangement of a vehicle system, and corresponding redundant sensor arrangement

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.
