The National Highway Traffic Safety Administration is seeking comments on an advanced notice of proposed rulemaking that could lead to camera-based, rear-visibility systems replacing mirrors on heavy trucks and cars.<\/p>\n
The ANPRM, published in the Federal Register on Oct. 10, is in response to two rulemaking petitions from manufacturers seeking permission to install camera monitoring systems on light vehicles and heavy trucks, reports Transport Topics. The ANPRM builds on the agency\u2019s prior efforts to obtain supporting technical information, data and analysis on camera monitoring systems so that it can determine whether the systems can provide the same level of safety as the rearview mirrors currently required under federal regulations.<\/p>\n
The agency said its responsibility in carrying out its safety mission is not only to develop and set safety standards for new motor vehicles and motor vehicle equipment, but also to modify existing standards to respond to changing circumstances, such as the introduction of new technologies.<\/p>\n
\u201cExamples of previous technological transitions that triggered the need to adapt and\/or replace requirements in the Federal Motor Vehicle Safety Standards include the replacing of analog dashboards by digital ones, the replacing of mechanical control systems by electronic ones and the first production of electric vehicles in appreciable numbers,\u201d the agency announcement said.<\/p>\n
Comments to the agency must be submitted by Dec. 9.<\/p>\n
Under current law, trucks and buses must have two outside mirrors positioned to show the driver a view of the highway to the rear, and the area along both sides of a commercial motor vehicle.<\/p>\n
An October 2018 NHTSA \u201cexamination\u201d of a passenger car equipped with a rear-camera system showed that while system display glare caused by sunlight was a foreseen issue, only minimal such glare was observed.<\/p>\n
\u201cCMS image clarity was good, comparable to that of outside rearview mirrors,\u201d researchers concluded. \u201cVisibility was especially good during dusk and dawn conditions when the displayed areas appeared brighter than would be seen with traditional mirrors.\u201d<\/p>\n
However, aspects of the prototype system\u2019s performance included excessive blooming and lens flare from headlights of other traffic at night, the examination concluded.<\/p>\n
\u201cOther issues included image obscuration due to water droplets remaining on the camera lens while driving and high display brightness that in dark driving conditions may glare and annoy drivers, as well as make discerning of forward objects more difficult,\u201d researchers said. \u201cIt is currently unclear whether these issues may be adequately remedied in a cost-effective manner.\u201d<\/p>\n
NHTSA said it has been made aware through media reports that some portion of the driving population may not be \u201cphysiologically capable of using the rear-camera systems.\u201d<\/p>\n
Although NHTSA said it believes that CMS is a promising technology, the agency has some lingering safety concerns that it believes should be addressed prior to deciding whether to propose amending federal regulations to permit CMS as a compliance option for rear visibility.<\/p>\n
\u201cNHTSA invites comments on all aspects of permitting camera-based technologies to be installed as an alternative to mirrors to meet the FMVSS No. 111 rear visibility requirements,\u201d the announcement said. \u201cHowever, the agency requests that commenters provide as much research, evidence, and\/or objective data as possible to support their comments to inform the agency in determining the appropriate next steps.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
