ACCELERATING SOFTWARE-DEFINED VEHICLE DEVELOPMENT
 
The automotive industry is undergoing a transformation, shifting from hardware-driven design to Software-Defined Vehicles (SDVs) that evolve through continuous updates.

At VI-grade, we empower this revolution by providing cutting-edge simulation and Digital Twin technology to accelerate vehicle development while optimizing both performance and user experience.

Traditional development methods are being replaced by agile, continuous software integration, ensuring vehicles remain adaptable long after production.

With our advanced virtual testing solutions, automakers can efficiently validate features such as ADAS, NVH, HMI and vehicle dynamics without relying on physical prototypes, leveraging key innovations in SDV development such as:

  • Digital Twin Technology – Test vehicle software in a virtual environment before building a single prototype.
  • Continuous Software Integration – Enable vehicles to evolve post-production through over-the-air updates.
  • DataDrive Approach – Merge data simulation with human feedback for a dynamic and realistic testing process.
  • Zero Prototypes Lab – Combine cloud simulations with real-time driver feedback for comprehensive validation.

One solution
for every need

Complete
workflow
Our simulators allow adding real-world elements to the environment, making them the most complete engineering tools. Hardware-in-the-Loop components such as real ECUs, radars, and cameras for ADAS applications can be also added to the simulation scenario, resulting in infinite, high-correlation possibilities.
Unique
architecture
Our dynamic simulators are based on a patented concept. The lower part moves on air pads with 3 main actuators or cables, providing a realistic driving experience with redundant movements. The upper part allows for fast response and high frequency, making them particularly suitable for ride & comfort studies.
Open
environment
VI-grade provides a complete set of software packages for our driving simulators, including VI-CarRealTime, VI-WorldSim, and VI-MotionCueing. Through our VI-Certified program, we support interfaces with all major real-time vehicle models, advanced tire models, traffic simulation software, and Hardware-In-the-Loop platforms.

Applications

It’s all about fine tuning your chassis, developing the right balance, selecting the right tires, tuning the transmission, setting up seamless control systems, to achieve the best driver experience.
Design and engineer the sound of your vehicle to meet brand and customer expectations, before building the first prototype.
Test your algorithms and automatic systems in a safe and collaborative environment, to validate ADAS functions integrating software and hardware sensors.
Evaluate your HMI criteria with a real car cockpit and dashboard and develop new interfaces, in a controlled and easy-to-modify environment.
VI-grade driving simulators help put the driver in front of the toughest conditions, in the most realistic and safest way.
