Road vehicles. Test method to evaluate the performance of lane-keeping assistance systems
Published By | Publication Date | Number of Pages |
BSI | 2021 | 32 |
This document specifies test methods and performance metrics to evaluate the behaviour of a vehicle equipped with lane keeping assistance system (LKAS, see 3.2).
For this purpose, variables relevant to vehicle dynamics as well as controllability of a vehicle with LKAS and their measurement methods are defined.
A system requiring a driver intervention is excluded from the scope. This document applies to the vehicles of M1 category.
