What is ISO 19586- Vehicle dynamics simulation and validation about?
ISO 19586 is an international standard on heavy commercial vehicles and buses that discusses the task of evaluating the dynamic behaviour.
ISO 19586 specifies a method for comparing simulation results from a vehicle model to measured test data for an existing vehicle combination’s lateral stability according to driving tests. The comparison is made for the purpose of validating the simulation model for this type of test. A complete validation comprises the comparison for at least one tested vehicle and one variant of this vehicle, covered by a parameter variation in the vehicle model.
NOTE: ISO 19586 applies to heavy vehicles, including commercial vehicles, commercial vehicle combinations, buses and articulated buses (trucks and trailers with a maximum weight above 3,5 tonnes and buses and articulated buses with a maximum weight above 5 tonnes, according to ECE and EC vehicle classification, categories M3, N2, N3, O3 and O4).
Who is ISO 19586 - Vehicle dynamics simulation and validation for?
ISO 19586 on heavy commercial vehicles and buses is useful for:
- Manufacturers of trucks and buses
- Mechanical engineers
Why should you use ISO 19586 - Vehicle dynamics simulation and validation?
The dynamic behaviour of a road vehicle is the most important aspect of active vehicle safety.
ISO 19586 provides guidance regarding the pseudo-random and the single sine wave steering input to determine lateral stability by calculating the rearward amplification (RA) and yaw damping (D) of heavy commercial vehicles and buses. The variables of motion used to describe the behaviour of the vehicle are determined in ISO 19586.
ISO 19586 navigates you through the minimum vehicle model parameters and requirements to predict lateral dynamic behaviour in the linear range.
ISO 19586 specifies the principle for comparing simulation and physical test results.
Moreover, ISO 19586 guides you with the study of the vehicle dynamics and its behaviour on heavy vehicles under certain driver input like the steering wheel and braking systems. in this manner, you can ensure the vehicle line stability and handling that could be able to carry people safely, comfortably and economically.
