AUTOMATIC VEHICLE WHEEL BRAKING SYSTEM Russian patent published in 2020 - IPC B60T8/00 

FIELD: machine building.

SUBSTANCE: disclosed is wheel vehicle automatic braking system. Proposed system comprises wheel rpm transducers (1, 2, 3, 4) and technical vision device. Microcontroller (5) comprises unit (10) for analysing signals of wheel rpm sensors (1, 2, 3, 4), unit (11) for estimating vehicle motion parameters, unit (12) for identification of maximum values of friction coefficients of wheels sliding, unit (13) for prediction of maximum deceleration without wheels blocking, unit (14) for restriction of slowdown by rear obstacle, unit (15) optimization of control for prevention of collisions, unit (16) for generation of control signals, unit (17) for generating control actions on vehicle control elements (18): brakes (19), accelerator (20), steering wheel (21). Above units are made on the basis of microcontroller (5) with possibility of program execution. Threshold of actuation of brake system in unit (15) is set programmatically in multiple times less than maximum deceleration without blocking wheels to compensate for effect of possible prediction errors due to unaccounted factors. System comprises device (22) for input and display of tuning data. Device (23) for generating sound and light alarm transmits emergency control signal to unmanned vehicles located behind, and is connected to control device (17).

EFFECT: identification of adhesion of wheels with road surface, prediction of maximum deceleration without wheels blocking, limitation of slowdown by rear obstacle, optimum braking control.
