Title: FMVSS No. 124, Accelerator Control Systems Upgrade
Abstract: The agency is considering several revisions to FMVSS No. 124. First, we are considering revisions to the test procedures for vehicles with electronically controlled throttles as well as electric vehicles and hybrid vehicles. These test procedures are the product of several workshops and public meetings. We anticipate that all vehicles would be able to meet them because it would not involve changes to the existing basic requirements of the standard. Second, we are considering adding a new requirement for a brake-throttle override system on light vehicles. Under certain conditions, this would require that the braking system overrides the throttle control in the event of a conflict. All vehicle manufacturers are in the process of equipping all of their U.S. vehicles with such technology, if they have not done so already. We anticipate that this new requirement would accommodate the current and planned override technologies.
