Whole-Vehicle Testing Services
From R&D to Series Production One-Stop Verification
From vehicle networks, function integration and OTA updates to real-vehicle road testing, ZD Technology provides one-stop whole-vehicle testing services covering the journey from R&D to series production, safeguarding delivery at every stage and quality stability after SOP.
Service Overview
Whole-vehicle E/E architectures are moving from domain-based control toward centralized control, with deep hardware-software decoupling and smarter vehicle updates. ZD Technology has long been deeply engaged in whole-vehicle testing; drawing on project experience with next-generation E/E architectures, we have taken part in vehicle network and function testing for multiple models, helping customers verify whether vehicle communication is reliable, whether functions work well and whether the system is stable.
Six Test Modules
Covers the key stages of whole-vehicle R&D verification, and can be undertaken module by module or as a whole according to project milestones.
Whole-Vehicle Network Testing
Covers communication matrices, gateway routing, diagnostics and flashing, and network management verification for automotive Ethernet and CAN/CAN FD buses.
Whole-Vehicle Integration Testing
Functional integration verification for real vehicles and bench systems, covering cross-domain function interaction, power management and whole-vehicle behaviour consistency.
VMM Testing
Specific verification of whole-vehicle battery drain and quiescent power consumption, covering low-voltage energy management and multi-controller coordination of sleep/wake strategies.
OTA Testing
Verification of the update chain across the vehicle, the OTA server and the TSP platform, covering failed-update rollback and stress scenarios.
RVDC Testing
Functional verification of the whole-vehicle remote data terminal, covering signal acquisition accuracy, the reporting chain and cloud data consistency.
Real-Vehicle Road Testing
Scaled multi-city road testing with full-process monitoring of whole-vehicle network sleep behaviour and quiescent current, recording data to form traceable test records.
Industry Challenges We Solve
The verification complexity brought by architecture changeover and parallel vehicle models requires systematic testing capability to handle.
A Leap in Complexity with Architecture Changeover
New technologies such as automotive Ethernet, SOME/IP and AUTOSAR network management vastly expand the communication chain and verification boundary, making it hard for traditional test methods to cover.
Parallel vehicle models, densely packed milestones
Multiple vehicle model projects on the same platform advance in parallel, with trial-production and series-production milestones densely packed, concentrating pressure on test resource and manpower scheduling.
Risk of battery drain and quiescent power consumption
Low-voltage energy management and sleep/wake involve multi-controller coordination; once a defect reaches the market it turns directly into customer complaints and after-sales cost.
Fast software iteration, long update chain
Remote updates span the vehicle and the cloud, requiring chain debugging, stress testing and scenario verification within a limited window.
Strict quality traceability requirements
Electrical problems arising after SOP from insufficient test coverage lead to accountability, requiring the test process to be fully documented and problems traced back to their source.
Delivery Process and Quality Assurance
A standardized main process runs through the entire project, supported by risk, baseline, measurement and communication management mechanisms.
Requirement Analysis
Breaks down test requirements according to the customer's overall plan, defines a tiered test plan and tracks its implementation.
Test Case Design and Review
100% review coverage for test cases and requirements; once the review is passed, a test baseline is established and execution begins.
Test Execution
Advances in parallel by module group, with defects flowing through the platform throughout and fix progress measured weekly.
Reporting and Review
Outputs test reports and issue statistics by stage, with milestone reviews to attribute causes and drive continuous improvement.
▎Safeguards Throughout the Project
- Five-step risk closed loop: plan definition → identification and assessment → response planning → response execution → tracking and monitoring
- Platform-based defect management: one-click flow of test cases and defects, with custom workflows and plan-versus-actual curve tracking
- Measurement mechanism: defect metrics are reported weekly and at milestones to monitor fix progress
- Communication mechanism: kick-off meeting, weekly meetings, pre-milestone and wrap-up meetings, supported by daily and weekly reports
