Winterthur, June 2021 – The Kistler Group is launching the world's first wireless wheel force measurement system – an innovation that will massively reduce the effort involved in vehicle dynamics, durability and tire testing. The new KiRoad Wireless HDR features far-field telemetry compliant with the 2.4 GHz WLAN standard, and it can be used with existing RoaDyn wheel force transducers.
Vehicle developers use high-precision wheel force transducers (WFTs) to measure wheel forces and moments directly on the hub, yielding data that is especially critical for durability tests. These measurements are also used to evaluate vehicle dynamics and characterize tire performance. Wheel force transducers in the RoaDyn series were the first systems that used near-field telemetry to transmit data to the vehicle – and now, the measurement technology experts at Kistler have broken new ground yet again.
KiRoad Wireless HDR (High Data Rate) features remote wireless transmission for wheel force measurements – eliminating the need for time-consuming adaptations and cabling both inside and outside the vehicle. Automobile and tire manufacturers, suppliers to the automotive industry, research institutions and motorsport teams are among the many users who will benefit from reduced installation effort and easy operation – freeing up valuable time for over-the-road and on-track testing.
