This paper discusses two equipment layouts for measuring path data, vehicle sideslip angles and tire slip angles by using a gyrosystem, a vehicle speed-measuring unit with contact or non-contact speed sensor(s) and a computer. Measurement errors are analyzed in detail. Analyzing position errors by using vector analysis can produce very concise results. A method for eliminating the effect of vehicle roll on measurement is given. Some relations between measurement errors and instrument errors are derived using vector analysis. A practical and effective error correction method for vehicle path measurements is developed to obtain more reliable motor vehicle kinematic information.
