UN R79: Proposal for Supplement 2 to 03 series of amendments
Reference Number: GRVA/2019/19
Proposal to amend the draft text (GRVA/2019/9) submitted to resolve measurement concerns in the test requirements for ACSF of Category B1 and C by introducing provisions for tolerances, including:
inclusion of the position at which the lateral acceleration was measured and the position of the centre of gravity of the vehicle for better traceablility,
sampling rate of at least 100 Hz for dynamic testing,
specification of filters and cut-off frequency for determination of lateral acceleration,
option to measure “overriding force” torque via an internal sensor or an external device (e.g., steering robot).
Proposal for modifications to draft tolerances in the testing of ACSF B1 and C systems with regard to lane width, coordinate system, lateral acceleration, and overriding-force test.
