BS ISO 4138:2021

This standard BS ISO 4138:2021 Passenger cars. Steady-state circular driving behaviour. Open-loop test methods is classified in these ICS categories:

• 43.100 Passenger cars. Caravans and light trailers

This document specifies open-loop test methods for determining the steady-state circular driving behaviour of passenger cars as defined in ISO 3833 and of light trucks, such behaviour being one of the factors comprising vehicle dynamics and road-holding properties. The open-loop manoeuvres included in these methods are not representative of real driving conditions, but are nevertheless useful for obtaining measures of vehicle steady-state behaviour resulting from several specific types of control inputs under closely controlled test conditions.
