SUBSTANCE: invention relates to systems for preventing collision of vehicles when overtaking. In the method of preventing collision of cars, optical radiation from vehicles on with-flow and contra-flow lanes, as well as from the vehicle moving ahead is received at the overtaking vehicle.

In case of a risk of collision, signalling is made to prohibit overtaking on the contra-flow lane. The apparatus for implanting the method comprises two electro-optical transducers, an acceleration sensor, a velocity sensor, a sensor for the longitudinal slope of the road, a computer, a switch for input of information on geometric dimensions of vehicles, light and audio signalling devices.

SUBSTANCE: invention is intended to prevent collision of vehicles. When monitoring the surrounding space, a first initial state is obtained for a first object (18) located in the surrounding space (14) as a reference point during a first stopping event, wherein the initial state includes an indication of the initial position of the first object (18). During a second stopping event (S1), a determination (S2) is made of whether a vehicle (10) has moved between the first and second stopping events by a given minimum distance and/or whether a given minimum time has passed. The initial state is refreshed (S3) by indicating the position of at least a second object (18) located in the surrounding space (14) as a reference point if it is determined that a vehicle (10) has moved between the first and second stopping events by a distance exceeding the given minimum value and/or that a time greater than the given minimum time has passed. The actual position of the second object (18) is determined (S5) as the actual state for further intent to begin movement. A possible collision situation is detected (S6) if comparison of the actual and the initial state yields a distance greater than a given value. The invention also relates to an anti-collision apparatus.
