Driver-Vehicle Interface Considerations for Lane Keeping Assistance Systems
The purpose of this document is to provide guidance for the implementation of lane keeping assistance systems (LKAS) driver-vehicle interfaces (DVI). LKAS provide support for safe lane keeping operations by drivers through automated vehicle system intervention, but do not perform automatic driving, nor prevent possible lane or roadway departures. LKAS include both LKAS centering-type systems (hereafter LKASCENTERING), which perform constant steering correction to maintain lane center positioning and LKAS intervention-type systems (hereafter LKASINTERVENTION), which only intervene to inhibit a lane departure if the driver fails to initiate corrective action. This document addresses DVI parameters for both system types. Where necessary, unique specifications are given for each system type; otherwise, specifications apply to both system types. The responsibility for the safe operation of the vehicle always remains with the driver. LKAS is intended to operate on highways and equivalent roads. This document applies to original equipment LKAS for light-duty vehicles (i.e., passenger cars and light trucks) with GVWR of less than 10,000 pounds. This document does not apply to the installation of LKAS on motorcycles or medium- and heavy-duty vehicles. Finally, this document does not address system or operational requirements for LKAS systems, which are being addressed by TC204/WG14 ISO 11270.
