Federal Motor Vehicle Safety Standards; Hydraulic Brake Systems; Passenger Car Brake Systems

摘要

This document amends Federal Motor Vehicle Safety Standards Nos. 105 Hydraulic Brake Systems and 135 Passenger Car Brake Systems to accommodate the brake systems on electric vehicles. The amendments address unique characteristics of brake systems on electric vehicles, such as regenerative braking, and are intended to assure safe performance for those brake systems. The amendments of Standard No. 105 apply to electric trucks, buses, and multipurpose passenger vehicles. They also apply to electric passenger cars that have not availed themselves of the option of conforming to Standard No. 135, which is mandatory for all passenger cars manufactured on and after September 1, 2000. The amendments to Standard No. 135 complement those made to Standard No. 105.
