The mandatory implementation date of GB 45672-2025 is July 1, 2027, with only 14 months remaining. While most people know the timeline, few understand the real industry dynamics, hot project progress and information asymmetry status in 2026 Q1.
·Industry AECS Development & Application Exchange Conference held by China Automotive Engineering Research Institute (CAERI) in Chongqing on March 19, 2026, gathering nearly 100 experts from chip modules, complete vehicles, auto parts, certification testing and platform operation sectors. Co-organizers cover test solutions, platform operation, voice acoustic processing and terminal R&D, reflecting full industrial chain collaborative layout for eCall compliance.
·Talent market demand explosion: A large number of M1/N1 new vehicles need phased compliance verification before the transition deadline. Traditional 2G/3G eCall testing talents cannot meet LTE/5G GB 45672-2025 requirements. Compound talents proficient in communication underlying protocol, Beidou positioning analysis, collision signal linkage and acoustic performance evaluation are in severe short supply.
2. Three Core Pain Points Confusing Automakers
Most automakers have finalized system architecture solutions, trapped in three key difficulties:
-Voice Call Performance ComplianceBased on GB/T 45314-2025, mandatory indicators include loudness, frequency response, duplex performance, echo and noise suppression. GB 45672-2025 adds mandatory driving position call performance and post-collision communication effectiveness requirements, directly affecting microphone selection, acoustic algorithm tuning and power amplifier calibration.Rumors of mandatory Chinese language testing, dedicated Chinese corpus and full rear seat voice testing have no standard basis, avoiding misleading R&D formulation.
-Model Change Boundary DefinitionThe biggest practical problem lies in change management. Clear judgment rules:
·Mandatory re-certification & filing: Communication module model replacement, positioning chip scheme upgrade, AECS main hardware iteration.
·Need professional evaluation & supplementary testing: Acoustic algorithm adjustment, collision trigger threshold modification, MSD message format & sending strategy change.
·Exempt from any filing: Vehicle appearance redesign, infotainment system UI OTA upgrade, non-safety parameter adjustment.Clarifying this boundary avoids unnecessary repeated testing costs.
·Local Emergency Platform DockingMany enterprises underestimate background platform docking workload. China adopts localized platform access specifications for message protocol and rescue center docking; vehicle terminal hardware & software compliance is only half the process, with real platform protocol connectivity unavoidable. Involve platform access partners in the early solution design stage to avoid later project rework.
3. Testing Equipment & Industry Capacity Status
Complete test capabilities including base station simulation, 5G communication testing, Beidou positioning verification, collision signal linkage and vehicle acoustic testing have been fully established in domestic authoritative laboratories. Core test equipment supports LTE/5G dual-cell simulation, collision scenario simulation and MSD decoding with automated batch testing scripts; hardware equipment is not the industry bottleneck.
The real bottleneck is professional talents: Novices cannot be proficient in GB 45672-2025 localized rules in 3-6 months; eCall testing requires cross-disciplinary knowledge of communication protocol, Beidou positioning, collision signal linkage and audio acoustic evaluation.
