ISO/TC 22/SC 33/WG 11 - Simulation

A systematic framework has been created that facilitates the definition of the requirements of simulation models for certain applications and driving manoeuvres in a standardized manner. For this purpose, the proposed framework systematically divides the vehicle model into model classes and all model classes into different model types, corresponding to various model characteristics and common modelling methods. The vehicle dynamics manoeuvres have been additionally structured and clustered. Manoeuvres can be assigned to model classes and model types using an allocation and requirements table. This document thus also creates the basis for model recommendations relevant to vehicle dynamics with regard to advanced driver assistance systems and automated driving (ADAS/AD). The application of the framework and the specification of the model requirements are the responsibility of the user. Alternatively, they may be determined by other regulations and standards. This document contains recommendations for selectable model characteristics in terms of adequate simulation quality with respect to performance tests and associated application patterns. The recommendations can be adapted accordingly to be applied to functional testing.

This document specifies methods for comparing computer simulation results from a vehicle mathematical model to measured test data for an existing vehicle according to ISO 7401. The comparison is made for the purpose of validating the simulation tool for this type of test when applied to variants of the tested vehicle. It is applicable to passenger cars as defined in ISO 3833.

ISO 19364:2016 specifies a method for comparing computer simulation results from a vehicle mathematical model to measured test data for an existing vehicle according to steady-state circular driving tests as specified in ISO 4138 or the Slowly Increasing Steer Test that is an alternative to ISO 4138. The comparison is made for the purpose of validating the simulation tool for this type of test when applied to variants of the tested vehicle. It is applicable to passenger cars as defined in ISO 3833. NOTE The Slowly Increasing Steer method is described in regulations such as USA FMVSS 126 "Federal Register Vol 72, No. 66, April 6, 2007" and UN/ECE Regulation No. 13-H, "Uniform provisions concerning the approval of passenger cars with regard to braking".

ISO 19365:2016 specifies a method for comparing computer simulation results from a vehicle mathematical model to test data measured for an existing vehicle undergoing sine with dwell tests that are typically used to evaluate the performance of an electronic stability control (ESC) system. The comparison is made for the purpose of validating the simulation tool for this type of test when applied to variants of the tested vehicle. It is applicable to passenger cars as defined in ISO 3833.
