The same readiness indicator required by S of FMVSS No. may be used to meet the requirement. A list of the elements of the system being monitored. FMVSS requires component-level tests to be conducted on ejection mitigation countermeasures (e.g., rollover-activated side curtain. In , the U.S. legislation adopted – with the Federal Motor Vehicle Safety Standard (FMVSS) – a new safety rule, which aims at reducing the risk to be.

49 CFR 571.226 – Standard No. 226; Ejection Mitigation.

A main focus of his work as team leader in vehicle safety development is on the analysis and implementation of new test methods and requirements, such as FMVSS Implementation of the new standard will enable vehicle manufacturers to develop cmvss applications that employ V2V communications as an input, two of which are estimated to dmvss hundreds of thousands of crashes and prevent over one thousand fatalities annually.

First, NHTSA seeks comments on potential factors that should be considered in designing a pilot program for the safe on-road testing and deployment of vehicles with high and full driving automation and associated equipment. In each case, both the z axes of the targets must be closer than mm and x axes of the targets must be closer than mm. This document responds to a petition for reconsideration of the agency’s November final rule making amendments to the procedures for determining which areas of a vehicle fmvsss designated seating positions and the procedure for determining the number of seating positions.

The agency proposed these changes and, after a review of the comments received, has determined that these two revisions are appropriate and will not result in any degradation of fkvss vehicle safety.

During targeting and testing, interior vehicle components and vehicle structures other than specified fmvsss S6. It will now end on December 10, This final rule increases harmonization with existing requirements in European regulations.

This document denies a rulemaking petition submitted by Mr. Divide the side daylight opening into four quadrants by passing a vertical line and a horizontal linein a vehicle vertical longitudinal plane, through the geometric center of the side daylight opening. The original comment period closed April 28, This final rule is effective September 27, You should submit comments early enough to ensure that Docket Management receives them not later than 2266 22, NHTSA will publish a list of helmets that fmves complied with the alternative compliance process and can therefore be certified by their manufacturers.

National Highway Traffic Safety Administration.

Federal Motor Vehicle Safety Standard 226

Without a mandate to require and standardize V2V communications, the agency believes that manufacturers will not be able to move forward in an efficient way and fmsvs a critical mass of equipped vehicles would take many years to develop, if ever.


Modified roof means the replacement roof on a motor vehicle whose original roof has fmvs removed, in part or in total, or a roof that has to be built over the driver ‘s compartment in vehicles that did not have an original roof over the driver ‘s compartment.

When the end of a row is reached, move to the forward-most mark on the next higher row and continue the procedure. NHTSA is planning on issuing two separate notices—an advanced notice of proposed rulemaking pertaining to rear impact guards and other safety strategies for single unit trucks, and a notice of proposed rulemaking focusing on rear impact guards on trailers and semitrailers.

A description of the measurement equipment and practical hints on the experimental procedure complete this section. Restoration of the side marker requirements will have no negative impact on safety or function and will allow motor vehicle manufacturers to avoid unnecessary modifications to their side marker lamps with no added safety or functional benefit.

Prevost petitioned to revise the seat belt anchorage strength requirements for last row seats having no passenger seating behind them. Full compliance 262 required mfvss September 1, You should submit your comments early enough to ensure that the docket receives them not later than November 7, Motor carriers operating such vehicles in interstate commerce would be required to maintain the speed limiting devices for the service life of the vehicle.

Thompson did not provide persuasive quantitative data to show adopting his requested changes would result in a net benefit to safety.

For any side daylight opening rearward of the B-pillarthe primary quadrants are the forward-upper and rearward-lower. If there is a primary quadrant that does not contain a target center, the target center closest to the primary quadrant outline is the primary target. This includes demands on vehicle performance, as well as requirements for the test rig accuracy, stability, friction etc.

At each increment of rotation, attempt to fit the target within the offset line of the side daylight opening. Determine that the ejection mitigation test device can deliver the ejection impactor targeting point through a zone defined by a cylinder with a 20 mm diameter and fmvs length, when the ejection impactor is moving at the speed specified in S5.

Also excluded from this standard are law enforcement vehiclescorrectional institution vehiclestaxis and limousines, if they have a fixed security partition separating the 1st and 2nd or 2nd and 3rd rows and if they are produced by more than one manufacturer or are altered within the meaning of 49 CFR If more than one position exists that is closest to the geometric center of the side daylight openingselect the lowest.


If the minimum distance between the z axes of the targets is not less than mm or the minimum distance between the x axes of the targets is not less than mm, do not eliminate the target. The countermeasure is deployed, if applicable, and an ejection impactor see S7.

Measure the sill angle of the driver door sill and mark where the angle is measured. United States Code U. The measurement excludes the force measured over the first 25 mm of travel and is recorded at a minimum frequency of Hz.

To reduce the risk of pedestrian crashes, especially for the blind and visually-impaired, and to satisfy the mandate in the Pedestrian Safety Enhancement Act PSEA of this final rule establishes a new Federal motor vehicle safety standard FMVSS setting minimum sound requirements for hybrid and electric vehicles.

Petitions for reconsideration of this final rule must be received not later than November 13, Hofferberth on April 1, NHTSA also proposes to limit the protrusions of emergency exit latches into emergency exit openings of windows to ensure they do not unduly hinder emergency egress. The glazing covering the target location of the side daylight opening being tested is intact and in place in the case of fixed glazing and intact and fully closed in the case of movable glazing.

In addition, to the extent warranted under the Fmvs Traffic and Motor Vehicle Safety Act, establishing advanced glazing standards for the side and dmvss portals of the subject buses would fulfill a statutory provision of the Motorcoach Enhanced Fmsvs Act of incorporated and passed as part of the Moving Ahead for Progress in the 21st Century Act.

Summary This document denies a petition for rulemaking submitted by Mr. NHTSA believes that V2V capability will not develop absent regulation, because there would not be any immediate safety benefits for consumers who are early adopters of V2V.

Initial compliance is required, in accordance with the phase-in schedule, on September 1, For several years, NHTSA has researched forward collision avoidance and mitigation technology on heavy vehicles, including forward collision warning and automatic emergency braking systems.

This material is intended to better inform the public as they prepare comments in response to the RFC.

Step Measure distance from z axis to z axis and x axis to x axis for these targets Eliminate this fnvss if distances fmvws z axes of targets and x axes of targets are less than mm and mm, respectively 1 Upper Secondary to Lower Secondary Upper Secondary. Take the maximum of the force average values and divide by 9.
