Method for testing at least one control device function of at least one control device

A method for testing at least one control device function of at least one control device of at least one first vehicle by means of a simulator having a plurality of computing units, the first vehicle having at least one environmental sensor, the method comprising:

• a multiplicity of environmental sensors of the first vehicle and/or of at least one further vehicle supplying the at least one control device and/or further control devices with sensor data of the environmental sensors, the at least one control device function processing at least some of the sensor data as input variables, and the first vehicle and, if present, the further vehicles being located in surroundings which represent a traffic situation,
• the first vehicle being simulated by means of a first vehicle model, and, if present, the further vehicles being simulated by means of further vehicle models the environmental sensors being simulated by means of sensor models, and the surroundings being simulated by means of an environmental model with the computing units of the simulator, the models being distributed alone or in groups between at least two computing units, each with a directly accessible memory,
• wherein the environmental model comprising static environmental data and dynamic environmental data,
• the sensor models having, as input variables, the static environmental data and/or dynamic environmental data,
• wherein,
• the sensor models are distributed between at least two computing units, each with their directly accessible memories,
• wherein there is identification of the computing units which have sensor models which have static environmental data as input variables,
• wherein the static environmental data is stored in the directly accessible memories of the identified computing units,
• wherein, after the storage of the static environmental data has been completed the simulation of the models on the computing units with their respectively directly accessible memories is started synchronously,
• wherein the sensor models which have the static environmental data as input variables use the static environmental data of the identified computing unit which has its directly accessible memory and on which the respective sensor models are themselves located.
