METHOD FOR PREVENTION OF CAR COLLISIONS WITH OBSTACLES AND SYSTEM FOR ITS REALISATION Russian patent published in 2008 - IPC G08G1/16 

FIELD: transportation, safety arrangements.

SUBSTANCE: in suggested method impulse signals from wheels rotational velocity sensors are recorded and inputted to data processing unit. Values of physical variables defining vehicle condition and limit values of physical variables are determined in real time according to values of wheel rotational velocities. At the output of data processing unit, signal is generated which contains information about approximation of physical variables defining vehicle condition to limit values or about exceeding the limit values. Depending on physical variables values and limit values of physical variables defining vehicle condition, the signal with control action preventing vehicle contact with obstacle is generated. Suggested system contains wheels rotational velocity sensors. Data processing unit includes microprocessor being able to identify the operative conditions of wheels rotational velocity sensors, to determine in real time the values of physical variables defining vehicle condition and limit values of physical variables according to values of wheels rotational velocities, and to generate signal containing information about approaching of mentioned values of physical variables to limit values or exceeding limit values.

EFFECT: group of inventions allows preventing typical collisions.
