SAE J3155_202604

This SAE Recommended Practice provides test protocols with performance requirements for camera monitor systems (CMS) to replace existing statutorily required inside and outside rearview mirrors for U.S. market road vehicles. This practice expands specific technical content while retaining harmonization with the FMVSS 111 rear visibility standard and other international standards. This is accomplished by defining required roadway fields of view as specific fields of view (FOV) displayed inside the vehicle. Specific testing protocols and/or specifications are added to enhance ease of use using straightforward language, and any specifications are intended to be independent of different camera and display technologies unless otherwise explicitly stated. To address demands for increased blind spot coverage and improving rearward indirect visibility by replacing rearview mirrors with camera monitor systems (CMS). CMS can offer wider and taller field of view coverage rearward of the vehicle in daytime, nighttime, and in varying weather and environmental conditions and can offer increased situational awareness to the vehicle operator. Additionally, replacing rearview mirrors with CMS can improve direct sideways vision, reduce neck rotation angle, and improve energy efficiency.
