Draft national standard for passenger-car steer-by-wire released for consultation
China’s Ministry of Industry and Information Technology has issued a draft mandatory national standard for steer-by-wire systems, marking a new stage in standardising steering technology.
Selecting acoustic sensors for EV low-speed alert testing: five considerations
Acoustic vehicle alerting systems (AVAS) support pedestrian safety. UNECE R138, China’s GB/T 37153-2018 and US NHTSA requirements specify alert sound levels and frequency characteristics.
Vehicle noise testing advances in accuracy and scenario coverage
From combustion-engine noise to electric-vehicle pedestrian alerts, vehicle noise affects performance, comfort and road safety. Testing is expanding towards higher accuracy and broader operating-condition coverage under UNECE regulations and Chinese standards.
New emergency braking requirements: automatic avoidance from 2028
GB 39901-2025 introduces mandatory AEB for all light vehicles from 1 January 2028, as described in this article.
Preparing for GB 21670-2025: braking tests for manufacturers and inspection organisations
GB 21670-2025 replaces the 2008 passenger-car braking standard as braking becomes increasingly electronically controlled. Requirements for electronically transmitted braking and functional safety bring new challenges and opportunities for vehicle testing.
