ADAS Testing with Virtual Test Drives

Scenario-Based Testing Across All Development Stages With DYNA4
Request a TrialTalk to an Expert

DYNA4 is a modular simulation environment for function development and validation of ADAS/AD with virtual test drives. 

Virtual vehicles, sensors, traffic, and environment models facilitate reproducible, high-coverage test scenarios across all development stages. DYNA4’s 3D environment simulation with road infrastructure and traffic provides virtual test fields for assisted and automated driving wherever environment perception plays a key role.  

From MIL to HIL and VIL, DYNA4 integrates flexibly into existing toolchains and accelerates reliable function validation.

Advantages

  • Test comprehensively
    Reproducible test driving of thousands of kilometers with parameter variations and test automation
  • Fail fast
    Lower development costs through correction of malfunctions early in the ADAS/AD development process
  • Reduce efforts
    Smooth integration into the Vector toolchain and 3rd-party toolchains
  • Improve safety
    Simulation of critical traffic and collision scenarios without harm
     

Application Areas

  • Environment perception: Lane detection, traffic sign recognition, object detection, simultaneous localization and mapping (SLAM) etc.

  • Comfort functions: Adaptive cruise control (ACC), parking pilot etc.

  • Safety systems: Pre-crash, forward collision warning (FCW), automated emergency braking (AEB), lane keeping assistant (LKA, ELKA), blind spot monitoring etc.

  • V2X: Connected and cooperative driving

  • Driving automation: Traffic jam chauffeur, highway pilot, driverless vehicles

  • On object level: object lists, detected lanes, etc.
  • On perception level: radar range-doppler map, camera image, segmented camera image, lidar point cloud, segmented lidar point cloud, ultrasound histogram, etc.
  • Realistic sensor movement due to physically correct dynamic behavior of the vehicle under test

One or More Vehicles Under Test

  • Realistic driving dynamics: Start with basic vehicle dynamics switch to full axle and tire dynamics, if necessary
  • Passenger cars and commercial vehicles with up to two trailers
  • Ready-to use example vehicles
  • Several vehicles under test at the same time in one environment (e.g. for platooning)
  • Actuation of motor/engine torque, brakes, steering etc.
  • Driving tasks for driver
