Abstract:

The Pedestrian Safety Enhancement Act (PSEA) of 2010 requires NHTSA to conduct a rulemaking to establish a Federal Motor Vehicle Safety Standard requiring an alert sound for pedestrians to be emitted by all types of motor vehicles that are electric or hybrid. NHTSA completed acoustic measurements for hybrid and electric heavy-duty vehicles (gross vehicle weight rating over 10,000 lb.) and for electric motorcycles. This acoustic data analysis was conducted to support activities related to the PSEA.

The measurements protocol used follows general procedures in SAE J 2889/1, Measurement of Minimum Noise Emitted by Road Vehicles, May 2012. Two electric motorcycles were tested at the Transportation Research Center in Columbus, Ohio. The test surface conforms to ISO 10844:2011 specifications. One electric vehicle delivery truck was tested at Navistar’s Fort Wayne, Indiana, proving grounds. The test surface conforms to an ISO 10844:1994 surface that is suitable for heavy vehicles.

In addition, screening data for four hybrid and electric heavy-duty vehicles were collected. The purpose of screening test was to obtain raw descriptions of the sound characteristics for a subset of heavy-duty vehicles. The measurements protocol used for the screening tests follows general procedures in SAE J 2889/1, Measurement of Minimum Noise Emitted by Road Vehicles. However the measurement protocol used for screening tests does not fulfill all the parameters stated in SAE J 2889/1. Several aspects are different, including the acoustic environment, operating conditions, test surface, number of microphones, and microphone position. Therefore the results obtained may deviate appreciably from the results obtained using specified conditions.
