METHOD OF ENSURING ACTIVE SAFETY FOR TRANSPORTATION VEHICLES MOVING IN FILE Russian patent published in 2010 - IPC G08G1/16 

FIELD: physics; control.

SUBSTANCE: invention relates to transport engineering and specifically to anti-collision systems for automobiles moving in a traffic stream. The method of ensuring active safety of transportation vehicles moving in a file involves availability of a system which has two antennae, two modulators, two power amplifiers, a mixer, a frequency converter, a detector, first and second speed detectors, range detector, a device for calculating dangerous distance, ground speed and approach speed, a continuous oscillation generator, an adder, circulator, Doppler filter and a comparator. The system has an antenna position control circuit, a first actuating circuit whose output is connected to a sound source, a second actuating circuit whose output is connected to a throttle valve, a third actuating circuit whose output is connected to the control unit of the antiskid system of the service handbrake system of the vehicle, a fourth actuating circuit whose output is connected to a light indicator.

EFFECT: more efficient control of speed of objects in a traffic stream.
