General Description:

The Smart Bump Integrator (BI) is a response-type road roughness measuring system designed to evaluate road surface condition by measuring the relative vertical displacement of a vehicle’s suspension with respect to the vehicle body.

The system records raw bump data and converts it into calibrated roughness indices such as IRI (International Roughness Index) using user-defined calibration equations.

When properly calibrated, the system delivers accuracy comparable to or exceeding conventional bump integrators.

Technical Specifications :
