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

摘要

A method 1 for testing at least one control unit (2) of at least one first vehicle (3a) by means of a simulator (5) having a plurality of arithmetic units (4a, 4b, 4c) is shown and described, wherein the first vehicle at least one environment sensor (6a), wherein a plurality of environmental sensors (6a, 6b, 6c, 6d) of the first vehicle (3a) and / or at least one further vehicle (3b), the at least one control device (2) and / or further control devices with sensor data of the environmental sensors (6a, 6b, 6c, 6d), which processes at least one control unit function (f) at least part of the sensor data as input variables, and the first vehicle (3a) and, if present, the other vehicles (3b) itself in an environment representing a traffic situation (7), wherein the first vehicle (3a) by means of a first vehicle model (12a), and, if available, the other vehicles (3b) by means of we vehicle models (12b) the environmental sensors (6, 6a, 6b) by means of sensor models (13, 13a, 13b) and the environment (7) by means of an environment model (14) with the computing units (4) of the simulator (5) are simulated, the models are distributed alone or in groups on at least two arithmetic units (4a, 4b), each with directly accessible memory, wherein the environmental model (14) comprises static (14a) and dynamic (14b) environmental data, wherein the sensor models (13) serve as input variables have static (14a) and / or dynamic (14b) environmental data. The most advantageous use of the simulator is achieved by distributing the sensor models 13, 13a, 13b to at least two arithmetic units 4, 4a, 4b, 4c with their directly accessible memories, respectively, that the arithmetic units 4b, 4c identify with sensor models 13a, 13b are the static environmental data 14a as input variables that in the directly accessible memory of the identified computing units 4b, 4c, the static environment data 14a are stored, that after completion storage of the static environment data 14a, the simulation of the models 12, 13, 14 on the computing units , 4a, 4b, 4c are started synchronously with their respectively directly accessible memories of the simulator 5 and that the sensor models 13a, 13b, which have static environmental data 14a as input variables, use the static environmental data 14a of those identified arithmetic unit 4b, 4c with their directly accessible memory on which the respective sensor models 13a, 13b themselves are localized.
