Summary:

The Mobile Tire Traction Dynamometer measures the braking and cornering traction of passenger car tires on outdoor pavements at highway speeds. Its hydrostatic wheel speed control system, wheel loading and positioning system, pavement wetting system, transducers and instrumentation are described in detail. The data processing methods for its several test modes are explained.Results of experiments (1) to determine the effect of the rate of change of slip on the peak braking coefficient, (2) to identify filters suitable for peak braking coefficient measurement, (3) to determine the effect of the rate of change of slip angle on the lateral force coefficient, and (4) to explore various pavement friction testing methods are included as examples of the use of this testing device
