Vehicle intelligent cockpit penetration reaches 75%–80%, and on-board voice interaction installation rate exceeds 80%. Lacking unified evaluation rules for a long time, GB/T 45314-2025 fills the industry gap with unified performance test specifications.
·Unify technical standards for vehicle manufacturers and parts suppliers to reduce communication disputes.
·Provide official arbitration basis for product publicity, user complaints and market supervision spot checks.
·Serve as a hard bonus for parts suppliers in manufacturer admission and project bidding.
2. Three Types of Enterprise Status
Leading automakers and first-tier suppliers have completed standard alignment; SMEs adopt a wait-and-see attitude without customer mandatory requirements; low-end vehicle manufacturers ignore the standard due to no voice configuration.
3. Core Assessment Content
Test hands-free call clarity, echo suppression and road noise adaptability; evaluate voice wake-up success rate, instruction recognition accuracy, far-field pickup and anti-interference ability under background music. Voice control of vehicle functions is not included; security constraints are governed by GB 44495.
4. Associated Standard Matching Logic
·GB/T 45314-2025: Performance specification for voice interaction and hands-free call.
·GB 44495-2024: Mandatory cybersecurity control for voice communication interfaces.
·ISO/SAE 21434: Whole vehicle security system framework for export and joint venture vehicles.
·Intelligent cockpit suppliers need dual compliance with performance (45314) and cybersecurity (44495).
5. Practical Q&A
Testing cycle: 1–1.5 months for full item testing; extended by rectification and retest. No unified fixed cost, quoted by test items and product complexity. No official validity period, subject to annual sampling rules of automakers.
GB/T 45314 sets unified evaluation criteria for the automotive voice industry, standardizing product performance measurement. For professional compliance consultation, contact Blueasia Testing & Certification Consultant: 13534225140
