FIELD: physics; control.
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. The radiation is then converted into electrical signals and, based on said information, the possibility of safe overtaking is determined for the overtaking vehicle, followed by signalling to the driver of the overtaking vehicle moving on the with-flow lane. 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.
EFFECT: safer overtaking.
