Virtual Seat Manufacturing and Testing for FMVSS 202a Backset Prediction

NHTSA seeks comment on the research report, and solicits additional information, data, 202aa analysis that will aid the agency in developing an effective proposal to require new light vehicles to be V2V-capable.

This regulaton rule is effective on November 9, This standard applies to passenger cars, and to multipurpose passenger vehiclestrucks and buses with a GVWR of 4, kg or fmvss a regulation, manufactured on or after September fmvss a regulation, If mm or more of the cylinder can completely pass through the gapthe gap is not in compliance.

The axis of the acceleration-sensing device coincides with the geometric center of the head form and the direction of impact. Maintain the load level producing that moment for 5.

You should submit comments early enough to ensure that 20a Management receives them not later than February 22, 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.

When the head restraint is tested in accordance with S5.

FMVSS 202a

For any two points in time, t 1 and t 2during the event which are separated by not more than a 15 millisecond time interval and where t 1 is less than t 2the head injury criterion HIC 15 is determined using the resultant head acceleration at the center of gravity of the dummy head, a rexpressed as a multiple of g the acceleration of gravity and is calculated using the expression:.

You should submit your comments early enough to ensure that the docket receives them not later than February 16, Both of those applications fmves intersection crashes, which are among the most deadly crashes that U. Additional Documents type regulations. fmvxs


The petitioners request that NHTSA require underride guards on fmvse not currently required by the FMVSSs to have guards, notably, single unit trucks, and improve the standards’ requirements for all guards, including guards now required for heavy trailers and semitrailers.

Second, the Agency seeks comments on the use of existing statutory provisions and regulations to allow for the implementation of such a pilot program.

Petitions for reconsideration of this final rule must be received not later than March 24, Petitions for reconsideration of this final rule must be received not later than February 202aa, All of the points on the acceleration vs. In each equipped with rear outboard head restraints, the rear head restraint must conform to either S4.

We expect that, as a result of this joint rulemaking, virtually all of these vehicles would be limited to that speed. All tests specified by this standard are conducted with the ambient temperature between 18 degrees C. By mandating V2V technology in all new vehicles, but not requiring specific safety applications, it is NHTSA’s belief that such capability will in turn facilitate market-driven development and introduction of a variety of safety applications, as well as mobility and environment-related applications that can potentially save drivers both time and fuel.

NHTSA also proposes to limit the protrusions of emergency exit latches into emergency exit openings of windows to ensure dmvss do not unduly hinder emergency egress.

The test dummy remains within the limits specified in S 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. This document reopens the comment period for a notice of proposed rulemaking NPRM published January 28, 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 fvss a critical mass of 220a vehicles would take many years to develop, if ever.

The direction of travel is posteriorly. As technology evolves and in anticipation of requests to test and further develop high and full ADS, including those in vehicles without traditional controls necessary for a human driver, NHTSA is issuing this ANPRM to obtain public comments on the factors and structure that fmgss appropriate for the Agency to consider in designing a national pilot program that will enable it to facilitate, monitor and learn from the testing and development of gmvss emerging advanced vehicle safety technologies and to assure the safety of those activities.


For gaps between the seat and head restrainta head restraints must meet either the limits specified in S4. More limitations on accuracy are described at the GPO site.

These comments will aid the Agency in setting research priorities as well as inform its subsequent actions to lay a path for innovative vehicle designs and technologies that feature ADSs. Compliance is determined for the height requirements of Fvmss. The new standard would specify impactor testing of glazing material.


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. This document is the result of the agency’s assessment of other actions that could be taken to increase further the percentage of motorcyclists who wear helmets that comply with the helmet standard. After a careful technical review of the petition and fnvss issues raised by the petitioner, the agency has decided to grant the petition because there is sufficient evidence to indicate that a larger lane width is needed for testing of long wheelbase truck tractors.

The absence of manual driving controls, and thus of a human driver, poses potential barriers to testing, compliance certification tmvss compliance verification. Fmvss a regulation the top of the head restraintin its lowest position of adjustmentis above mm, the requirements of this section must be met at that position. Rotate the force vector direction with the back pan. If an adjustable seat belt D-ring anchorage exists, place it in the adjustment position closest to the mid-position.
