Williams Advanced Engineering’s skilled manufacturing team designs advanced Vehicle Driving Simulators (aVDS) for AB Dynamics. The system is built to exacting manufacturing requirements and dimensions. . It is a versatile and innovative driving simulator, combining a high-performance motion platform and high specification audio and visual hardware with industry-leading virtual content. The result is a simulator capable of accurately representing the smallest changes to a vehicle’s configuration and an ideal instrument for the future of vehicle development.
Automotive industry standard manufacturing and quality principles are applied throughout assembly, with parts and processes controlled to stringent technical requirements.
The aVDS has been designed to reduce new vehicle development timescales and costs by allowing meaningful testing far earlier in the vehicle development process. The simulator can be used across a breadth of applications, including: vehicle dynamics, ADAS and autonomous systems, durability, hardware-in-the-loop, software-in-the-loop and driver monitoring. The ability to change suspension parameters on the fly or to conduct complex automated manoeuvres in chaotic traffic conditions is a level of capability that engineers dream of. Whether testing a pre-prototype model on a digital version of a chosen proving ground or assessing passenger anxiety as an autonomous vehicle negotiates the Arc de Triomphe in Paris, the aVDS gives unparalleled flexibility and freedom, without compromising safety.
In simulation, immersion is critical to maintain the authenticity of the driver’s experience and reactions. When designing the aVDS the objective was to be so involving and detailed that seasoned drivers could detect incremental parameter changes as if they were in a real car. Thanks to the high road surface fidelity reproduced by the aVDS, simulated results and data correlate closely with those attained by physically driving a real vehicle on a specific road or track. Visual, audio, haptic and vestibular cueing ensures that the driver is fully engaged with senses stimulated for an unmatched level of realism. The platform’s motion and visual feed have been precisely synchronised to eliminate the motion sickness often experienced when operating driving simulators.
The aVDS utilises high specification linear actuators to deliver class-leading 6DoF dynamic performance, with up to 60Hz frequency response, providing a tightly harmonised driving experience. The motion platform can be quickly configured to take a variety of payloads up to 500kg, facilitating the installation of real vehicle cabins. Advanced cueing effectively makes the already generous motion envelope seem even bigger. Faithfully recreated vehicle dynamics can be experienced in a variety of common tests, including: cornering, lane change, slalom, braking in turn, impulse, sine, step, ramp, swept steer, braking and more.
The aVDS has been designed to make vehicle and system development simpler and faster. AB Dynamics has ensured that the aVDS integrates seamlessly with the company’s other test equipment, providing a link between simulation, laboratory-based testing, and track testing.
