Cockpit Testing Services
Smart Cockpit Full-Chain Testing
From function, interaction and performance to user experience, ZD Technology provides full-chain testing services for smart cockpits covering requirement analysis, test case design, test execution, issue tracking and acceptance support, together with voice automation and large model / multimodal model testing.
Service Overview
Smart cockpit platform development faces persistent challenges: multiple vehicle models in parallel, rising software complexity and tightly packed delivery milestones. ZD Technology places an on-site R&D team with customers to carry out full-chain testing around the smart cockpit system, covering requirement analysis, test case design, test execution, issue tracking and acceptance support, safeguarding software delivery quality at every stage. The team works on site at the customer's R&D location with China–Germany collaboration, delivering against quantifiable test case and defect metrics.
Industry Challenges We Solve
The complexity and iteration speed of cockpit software place higher demands on the coverage capability and engineering maturity of the test team.
Multiple vehicle models developed in parallel
Under platform-based development, multiple vehicle model projects advance in parallel, cockpit software complexity keeps rising and delivery milestones are tightly packed, making it hard for in-house resources to achieve full coverage.
Difficult cross-subsystem integration testing
Cockpit functions span sub-systems such as vehicle control and settings, navigation, multimedia, voice, basic services and phone connectivity, and problems often only surface during cross-domain integration testing.
Lack of unified standards for experience metrics
Experience aspects such as start-up latency, interaction smoothness and multi-screen interaction lack a unified, reproducible quantitative definition.
Rapid iteration of voice and large model capabilities
Model capabilities such as intent understanding, rewriting and routing change quickly from version to version, requiring continuous, reproducible automated verification.
High requirements for defect flow efficiency
Defects must flow efficiently between the test and R&D teams and support stage acceptance.
Testing Service Capabilities
Covers the core stages of smart cockpit R&D verification, and can be undertaken as a whole or combined by module.
Function and Integration Testing
Covers functional testing and whole-vehicle integration testing for modules such as IVI, vehicle control and settings, navigation, multimedia, basic services and phone connectivity.
Performance and Stability Testing
Performance-specific testing such as start-up latency, resource usage and smoothness, plus long-duration stress and stability verification.
User Experience Testing
Quantitative evaluation of experience aspects such as interaction smoothness and multi-screen interaction, forming a reproducible evaluation standard.
Voice-Specific Testing
Full-process testing of voice wake-up, recognition and interaction; an in-house automation solution automates the whole chain of injection, capture, judgment and recording.
Large Model and Multimodal Testing
Quantitative evaluation of capability and performance for intent understanding, routing, rewriting, creative recommendation, knowledge base and in-cabin / exterior multimodal recognition.
Navigation and Real-Vehicle Road Testing
Navigation-specific testing and real-vehicle road test coverage, delivered in step with whole-vehicle integration and acceptance test milestones.
End-to-End Test Process and Process Control
A five-step closed loop runs through the entire project, supported by plan, risk and measurement management mechanisms.
Requirement Analysis
Analyzes requirement change points and vehicle model differences, updates test cases and provides analysis recommendations.
Test Case Design
Module design documents are provided, with 100% review coverage for test cases and requirements.
Test Execution
Delivers according to the vehicle model schedule and completes functional testing, sharing the workload of stability-specific and road-test tasks.
Issue Tracking
Platform-based defect flow and weekly measurement, tracking fix plans against actuals.
Acceptance Support
Submits test reports at milestones and supports stage acceptance and on-site joint debugging.
▎Safeguards Throughout the Project
- Multi-dimensional test plan breakdown: goals and strategy, staffing, functional / performance / automation / real-vehicle plans, quality and defect management, equipment resources and training support
- Five-step risk closed loop: plan definition → identification and assessment → response planning → response execution → tracking and monitoring
- Measurement mechanism: defect metrics are reported weekly and at milestones to monitor fix progress
- On-site delivery: the team works at the customer's site throughout the project and provides on-site support at production lines and other locations as needed
