METHOD TO DIAGNOSE AUTOMOTIVE BRAKES Russian patent published in 2010 - IPC B60T17/22 G01L5/28 G01M17/07

Abstract RU 2380247 C1

FIELD: automotive industry.

SUBSTANCE: proposed method comprises measuring the weight of tested axis G, force on control member P_P, specific braking force γ_BR, relative difference in braking forces of wheels fitted on axle F, average actual specific braking force γ_CVE, average actual Petrov's magnitude "Э", angular speeds of support and servo rollers, braking time of computation of estimate magnitudes, and current and average S_AVE wheel slippage values for braking time interval. Measurements are performed with due allowance for three new estimate magnitudes, i.e. factor of braking moment increase irregularity K_BMI, factor of vehicle wheel locking irregularity in time and turn K_II and moment of turning around M_TAR. Factor of braking moment increase irregularity K_BMI features difference in braking moment increase intensity in one-axle wheels. Factor of vehicle wheel locking irregularity in time K_II describes braking process. Moment of turning around M_TAR characterises stability of vehicle in braking.

EFFECT: higher validity of diagnostics.
