The related real-time test method for vertical adhesion feature between tyre and road comprises: arranging the testing tyre on a wheel of running test vehicle, detecting the drive torsion and wheel rate by sensor fixed on vehicle drive wheel, and obtaining the wheel rate omega of driven wheel by the sensor on driven wheel; according to the normal pressure N and wheel radius rw, calculating the adhesion factor mu and drive wheel trackslip rate lambda by formula (1) and (2). Wherein, it uses a data process SCM programmed as (1) and (2) to receive rate and torsion signal, calculate target value and send to note-book to record, store and display.
