16 Jan 2019 2019-01-25 13:52:54 UTC 8 6 11 series of amendments | Supplement 16 Based upon the adopted proposal: WP.29/2018/53

The 02 series of amendments to UN R79 introduced requirements for RCP systems. An RCP system requires the engagement of an EPB (electronic parking brake) once the manoeuvre has finished and the ignition is switched off. This proposal would allow the release or disconnection of the EPB by a remote control system (approved to R79) so the RCP can subsequently drive the vehicle out of a parking spot.
