METHOD FOR PREVENTION OF DRIFT AND SLIPPAGE OF CAR WHEELS Russian patent published in 2019 - IPC B60K28/16 B60T7/12 

FIELD: motor vehicle industry.

SUBSTANCE: invention relates to automotive industry, particularly, to active vehicle safety method. Signals generated by pulse wheel rpm transducers are registered and transmitted via interfacing unit to information processing unit. In the data processing unit at the current wheels speeds in real time, values of physical variables are determined and compared with the specified true values characterizing the critical state of the vehicle. Namely, in the unit for processing information in real time, estimating and predicting the predicted speeds of the vehicle center of gravity, the angle of turn of controlled wheels, top values of friction coefficients of wheels sliding, as well as boundary values of front drift speeds, and rear wheels slippage are calculated and generated. Further, based on signals on wheel rpm and tuning parameters using a microcontroller with software and, if the predicted center of mass velocity is exceeded by the minimum of predicted drift and slippage boundary velocities, generating control actions on accelerator and/or braking system control devices for automatic prevention of drift and/or slippage of car wheels and on indication device of braking to transmit to driver information on automatic mode of driving drift or slippage of car wheels and prevention of crash preconditions.

EFFECT: predicting and preventing drift and slippage of car wheels.
