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.

NHTSA is issuing this NPRM to propose a new Federal motor vehicle safety standard to enhance the rollover structural integrity of certain types of large gmvss generally, over-the-road buses of any weight and non-over-the-road buses with a gross vehicle weight rating GVWR greater than 11, kilograms kg 26, pounds lb.

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.

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. Today’s fmvxs would facilitate the introduction of new technologies including hydrogen fuel cell vehicles and 48 volt mild hybrid technologies, and responds not only to GTR No.

NHTSA seeks comments on the economic impact of its regulations on small entities.

Ejection propulsion mechanism means a device that is a component of the ejection mitigation test device consisting of a mechanism capable of propelling the ejection impactor and constraining it to move along its axis or shaft.

The documents referenced in this notification will be available in the docket as of April 16, This course is available as an in-house seminar.

This NPRM proposes rulemaking on these and other requirements to increase the correct use of child restraint anchorage systems and 2226 anchorages, and the correct use of child restraints, with the ultimate goal of reducing injuries to restrained children in motor vehicle crashes.

Public comments are welcome at this meeting, but all should be oral, and any supporting presentations or materials should be submitted to the docket for consideration.

Performance requirements would apply to side and rear windows, and to glass panels and windows on the roof to mitigate partial and complete ejection of passengers from these windows and to ensure that emergency exits remain 22 after a rollover crash.

Ejection Mitigation FMVSS 226: Requirements – Testing – Development Strategies

If after performing the procedure in this section, the remaining targets exceed the number of targets determined with the original orientation of the targetthe reoriented targets represent the final target locations for the side daylight opening. Measure the horizontal distance between the centers of the primary targets. The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register as of August 24, Global Automakers petitioned the agency for reconsideration, seeking to correct what it believes is an error in formula for determining the number of designated seating positions in longer seating positions.


For vehicles that have an ejection mitigation countermeasure that deploys in the event of a rollover, the vehicle manufacturer must make available to the agency, upon request, the following information: Further, the compliance test procedures of some FMVSS depend on the presence of such things as a human test driver who can follow instructions on test driving maneuvers or a steering wheel that can be used by an automated steering machine.

Federal Motor Vehicle Safety Standard – Wikipedia

The agency believes that requiring V2V communication capability in new light vehicles would facilitate the development and introduction of a number of advanced vehicle safety applications. Additionally, consumers can purchase their own tool and locate it in the vehicle where they would be likely to access it in an emergency. Finally conflicts with other safety requirements are identified and discussed. Apply the pressure only once at each mark location, even if the glazing does not break or no hole results.

You should submit your comments early enough to ensure that the docket receives them not later than September 21, The incorporation by reference of certain publications listed in the standard is approved by the Director of the Federal Register as of February 13, Place another secondary target center rearward of the forward primary target by two-thirds of the horizontal distance between the primary target centers and tangent with the lower portion of the offset-line see figure 4 figure provided for illustration purposes.

Summary This document grants the petition for rulemaking submitted by the Truck Safety Coalition, the Center for Auto Safety, Advocates for Highway fmvzs Auto Safety, and Road Safe America on February 19,to establish a safety standard to require automatic forward collision avoidance and mitigation systems on certain heavy vehicles.

NHTSA has granted Toyota’s petition and proposes to establish appropriate performance requirements to ensure the safe introduction of adaptive driving beam headlighting systems if equipped on newly manufactured vehicles. Side daylight opening means, other than a door openingthe locus of all points where a horizontal lineperpendicular to the vehicle vertical longitudinal plane, is tangent to the periphery of the opening.

This document denies a petition for rulemaking submitted by Mr. More limitations on accuracy are described at the GPO site.

If this distance is greater than or equal to mm, place a target such that its center bisects a line connecting the centers of the remaining targets. Target means the x-z plane projection of the ejection headform face as shown in Figure 1. Marianne Karth and the Truck Safety Coalition Petitioners requesting that the agency improve the safety of rear impact fvmss guards on trailers and single unit trucks.

The data available to the agency shows there is a great deal of uncertainty surrounding the actual number of occupants that may have died due solely to drowning while trapped in an immersed vehicle.

ESC systems in truck tractors and large buses are designed to reduce untripped rollovers and mitigate severe understeer or oversteer conditions that lead to loss of control by using automatic computer-controlled braking and reducing engine torque output.

Your contact person Dr. The compliance fnvss is September 1,with full phase in by September 1, The resulting value must not exceed 0. The Petitioners’ request to initiate rulemaking on rear impact guards on trailers and single unit trucks is granted on July 10, NHTSA will determine whether to issue a rule in the course of the rulemaking proceeding, in accordance with statutory criteria.

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

Zero displacement plane means, a vertical plane parallel to the vehicle longitudinal centerline and tangent to the most outboard surface of the ejection headform when the headform is aligned with an impact target location and just touching the inside surface of a tmvss covering the side daylight fmsvs. This notification announces the docketing and availability of this research. This document reopens the comment period for a notice of proposed rulemaking NPRM published January 28, It will now end on December 10, NHTSA believes that V2V capability will not develop absent regulation, because there 262 not be any immediate safety benefits for consumers who are early adopters of V2V.

The potential effectiveness of such a tool to successfully aid an occupant’s safe exit from an immersed vehicle is also not known. At the first increment of rotation where the target will fit, place the target center as close as possible to the geometric center of the side daylight opening. Motor carriers operating such vehicles in interstate commerce would be required to maintain the speed fmvsz devices for the service life of the vehicle.

Optional early compliance as discussed below.
