Conventional inertial measurement systems determine pitch and roll relative to the horizon, so road gradients and banked curves distort the results. The new HMS height measurement system from Sensoric Solutions eliminates this error: using laser triangulation, it measures vehicle height, pitch, roll and camber angle directly relative to the road surface.

The compact laser sensors (HMS 1) operate at over 1,000Hz with a repeatability below 0.1mm. Depending on configuration with up to four sensors, the system captures ride height at individual points, dynamic camber at the wheel, or simultaneous pitch and roll motion. An H-frame setup delivers dual roll signals and torsion data.

All sensor signals are synchronized in a central integrator unit and output via CAN/CAN FD. Combined with the OMS optical ground speed sensors, the HMS forms a fully synchronized measurement platform covering all vehicle dynamics parameters, from speed and side-slip angle to height and camber.

Sensoric Solutions will demonstrate the HMS live at Automotive Testing Expo in Stuttgart, for applications in chassis and suspension development, tire testing, motorsport and ADAS.
