Application Summary AI generated
This standard specifies the steering-pulse open-loop test method for evaluating the free-steer behaviour of passenger cars. It is applied in vehicle dynamics testing to assess how a car responds to a sudden, brief steering input without driver correction, typically during chassis development and homologation. The standard is used by automotive manufacturers and testing agencies to ensure predictable and safe handling characteristics in production vehicles.
