ADAS AEB Testing
ADAS & Active Safety

NCAP Validation (AEB/ACC)

The Pain Point: "Validating AEB requires knowing the exact distance between two moving vehicles at 100 km/h. Standard GPS latency is too high."

Don't guess the distance. Our IFS3000 ADAS System connects the Master Vehicle and Target Vehicle via low-latency Wi-Fi, calculating real-time range, lateral error, and Time-To-Collision (TTC) with 2cm accuracy.

  • Output:  Real-time V2V Distance & TTC
  • Standard:  Meets NCAP

Chassis Tuning & Slip Angle

The Pain Point: "Tire development requires precise Sideslip Angle measurement. Optical speed sensors often fail on wet or snowy tracks."

Capture every transient maneuver. Our Reference INS fuses GNSS velocity with a high-grade 250Hz IMU to calculate slip angle directly at the Center of Gravity (CoG), immune to surface conditions (snow, ice, sand).

  • Metric:  Slip Angle Accuracy < 0.15°
  • Feature:  CAN Output for Data Loggers

Benchmarking Your SLAM

The Pain Point: "How do you know if your Lidar localization is accurate? You need a trajectory that is 10x more precise than the DUT."

Establish the absolute truth. By using our DS Insight, you can, in real-time, generate a "Golden Trajectory" with sub-centimeter accuracy, perfect for calculating KPI error reports.

Ground Truth Decision Guide

Understanding the distinction between operational navigation and validation-grade reference systems.

A ground truth system is designed to provide a high-accuracy reference for evaluating and validating other sensors. Unlike navigation systems (optimized for real-time control), ground truth systems prioritize:
  • Accuracy & Repeatability: Serving as the "ruler" for measurement.
  • Time Synchronization: Precise alignment with DUT data.
  • Data Integrity: Relying on robust real-time sensor fusion algorithms for maximum reliability.
They are the benchmark against which system performance is objectively assessed.
Ground truth systems are the standard requirement for:
  • ADAS Validation: Benchmarking AEB, ACC, and Lane Keep Assist.
  • Sensor Benchmarking: Validating performance of new LiDARs, Radars, or Cameras.
  • Algorithm Evaluation: Testing SLAM and localization stacks.
  • Vehicle Dynamics: Precise slip angle and chassis measurement.
Accuracy is a function of system configuration and correction methods (RTK/PPK). DAISCH systems are designed to deliver:
  • Position: Centimeter-level accuracy (1-2 cm).
  • Orientation: Precise Heading (0.05°), Roll, and Pitch.
  • Repeatability: Stable performance suitable for regression testing.
Actual performance may vary based on environmental conditions (e.g., open sky vs. urban canyon).
Time synchronization is a core requirement for validation. DAISCH systems support:
  • PTP (IEEE 1588): For Ethernet-based sensor fusion.
  • PPS / Hardware Triggers: For hard-syncing cameras and LiDARs.
  • GNSS Timing: Absolute UTC alignment.
This enables accurate alignment of reference data with your perception sensors and logging platforms.
Yes. Our systems are agnostic and designed for integration into:
  • Vehicle Test Platforms: Compatible with Vector CANape, Dewesoft, etc.
  • Data Loggers: Standard interfaces (CAN/Ethernet) for easy recording.
  • Test Frameworks: DBC files and SDKs provided for automation.
Yes. DAISCH ground truth systems are built for:
  • Continuous Operation: Stable thermal management for all-day testing.
  • Data Consistency: Minimized drift over long duration data collection.
  • Scalability: Suitable for fleet-wide deployment in field tests.
Our systems support diverse testing environments:
  • Proving Grounds / Test Tracks.
  • Public Roads (Urban, Highway).
  • Off-road terrains.
For challenging environments like tunnels, our systems support tight integration with wheel speed sensors (Odometry) and dual-antenna configurations to minimize drift and maintain high accuracy.
They provide the "Golden Reference" data used to:
  • Quantify positioning errors (e.g., "My SLAM drifted 15cm").
  • Evaluate perception performance under various scenarios.
  • Support automated regression testing and KPI tracking over time.
They are the foundational component of any data-driven validation workflow.
Ground truth systems should be introduced early during:
  • Algorithm development (to tune parameters).
  • Early prototype validation (to catch bugs early).
  • Pre-production road tests (for final sign-off).
Early adoption helps identify performance gaps sooner and reduces risk during later stages.
We act as a partner in your validation process, providing:
  • Configuration Guidance: Selecting the right accuracy tier.
  • Integration Support: Assisting with antenna placement and lever-arm measurement.
  • Data Output: Ensuring your logs are synchronized and valid.
Our goal is to ensure the reference data you generate is reliable and meaningful.
