What is ISO 22140 about ?
ISO 22140 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.
ISO 22140 is applicable to passenger cars as defined in ISO 3833.
Who is ISO 22140 for ?
ISO 22140 on validation of vehicle dynamics simulation — lateral transient response test methods is applicable to:
- Passenger car manufacturers
- Vehicle testing laboratories
- Automobile engineers
- Vehicle regulatory authorities
Why should you use ISO 22140 ?
The dynamic behaviour of a road vehicle is a very important aspect of active vehicle safety. Any given vehicle, together with its driver and the prevailing environment, constitutes a closed-loop system that is unique. The task of evaluating the dynamic behaviour is therefore very difficult since the significant interactions of these driver–vehicle–environment elements are each complex in themselves. A complete and accurate description of the behaviour of the road vehicle necessarily involves information obtained from a number of different tests.
ISO 22140 provides a repeatable and discriminatory method for comparing simulation results to measured test data from a physical vehicle for a specific type of test.
ISO 22140 gives a test to demonstrate that a vehicle simulation tool can predict the vehicle behaviour within specified tolerances. A vehicle simulation tool is used to simulate a specific existing vehicle running through the open-loop tests specified in ISO 7401.
ISO 22140 lays out guidelines for data analysis and data presentation which will help you in understanding the results effectively.
