NHTSA proposes ESC for trucks and buses
NHTSA (U.S. National Highway Traffic Safety Administration) on May 16 proposed a rule to require that new large commercial truck tractors and buses be equipped with an electronic stability control (ESC) system. If and when the proposed rule is adopted, the mandate would take effect two years later for all new typical 6 x 4 truck tractors and four years for severe-service tractors and tractors with four or more axles. In justifying the lead times, NHTSA noted that there are only two suppliers of ESC systems for truck tractors and large buses: Bendix and WABCO. It said the current rate of ESC installation on new truck tractors is 18%.
EU approves test to prevent grid problems from vehicle charging
The United Nations Economic Commission for Europe (UN ECE) recently approved a measure designed to ensure proper electromagnetic compatibility between the electricity grid and vehicles (battery-electric and plug-in hybrid-electric types) that are being recharged via a plug, according to InterRegs, an online resource for global vehicle safety and emissions regulations. Compliance with these new requirements (in the form of the 04 series of amendments to Regulation No. 10) becomes mandatory from Oct. 28, 2014, for new types of vehicle and from Oct. 28, 2016, for all new vehicles.
Europe toughens truck cab safety test
The United Nations Economic Commission for Europe (UN ECE) on Jan. 4 published the 03 series of amendments to Regulation No. 29 on commercial vehicle cab safety which introduces some significant amendments to the pendulum impact test procedures, according to InterRegs, an online resource for global vehicle safety and emissions regulations. The changes increase the impact energy level for the existing front pendulum impact test from 44 kJ to 55 kJ, specify an additional front pendulum impact test designed to test the cab’s A-pillars, and require that the cab roof be subjected to a lateral pendulum impact prior to the roof crush test being conducted. Compliance with these new requirements becomes mandatory for new types of truck from Jan. 30, 2017.
SAE launches A/C conformance program and database
In response to industry and consumer requests, SAE International has developed a new program to provide conformance measures for the mobile air-conditioning (MAC) industry. Overseen by SAE International's Interior Climate Control Standards Committee, the program offers a procedure for certifying compliance with appropriate SAE International technical standards. It can be used by MAC manufacturers, along with testing facilities and providers of technical training. While certification of any product is voluntary, suppliers or manufacturers that advertise their products as certified to an SAE International “J” standard are required to follow the procedures established by the respective program (the organization has similar conformance programs addressing engine power ratings). In this case, the certification is designed to raise the level of confidence and to assure consumers of MAC components, equipment, and technician training programs that the providers are following and meeting the expected performance criteria set by SAE International standards. The program is governed by SAE J2911—“Procedure for Certification that Requirements for Mobile Air Conditioning System Components, Service Equipment, and Service Technician Training Meet SAE J Standards,” a revised version of which was issued in January. MAC industry suppliers may register for the program at http://macdb.sae.org/. The SAE MAC Manufacturer Database website also provides information about companies that have submitted claims of conformance. For more information, contact SAE conformance program manager Gary Pollak at gary@sae.org.
CARB sets fuel-efficiency rules for 2017-2025
The California Air Resources Board (CARB) on Jan. 27 adopted rules for fuel efficiency and greenhouse gas (GHG) emissions that largely align with proposed federal rules for the years 2017-2025 but add certain mandates designed to help automakers achieve the required fuel-efficiency and GHG levels. The CARB rules deviate most significantly from the federal rules in requiring minimum sales levels of full and partial electric vehicles (including hydrogen fuel-cell vehicles). One of the provisions calls for the construction of hydrogen filling stations. The effect of the rules will be to put more than 1.4 million plug-in-electric and fuel-cell vehicles on California roads by 2025. CARB expects the lifetime savings in fuel costs for the average vehicle buyer to be three times as great as the upfront costs of the advanced technologies developed and deployed to improve fuel efficiency. Unlike the federal program, which addresses only fuel efficiency and GHG emissions, the California rules also address NOx and particulate-matter emissions.
EU proposes lower vehicle noise limits
The European Commission have recently published a new draft regulation on motor vehicle sound levels, according to InterRegs, an online resource for global vehicle safety and emissions regulations. In addition to limiting noise levels, the proposal would establish a new procedure for measuring noise emissions and new requirements on the minimum sound generated by electric and hybrid-electric vehicles. The reduced noise limits would be implemented in two phases. In the first phase, applicable two years after the publication of the regulation, the noise limits applicable to heavy trucks would be reduced by 1 dB (A) to between 77 and 82 dB (A), dependent on engine power and drive configuration. The noise limits applicable to other types of vehicles would be reduced by 2 dB (A) to between 70 and 79 dB (A), dependent on vehicle type, GVWR, engine power, and drive configuration. In the second phase, applicable five years after the publication, the noise limits would be reduced by a further 2 dB (A) for all vehicle types.
