Zusammenfassung: | FIELD: physics. ^ SUBSTANCE: optical radiation from vehicles moving on the same and opposite lanes is simultaneously received at a car; said optical radiation is converted to electric signals; the distance to vehicles on the same and opposite lanes is calculated; the approach speed of said vehicles is calculated; geometric dimensions of the vehicle moving in the same direction are determined. Based on said information, light signalling is issued to keep a safe distance from the vehicle in front and on possibility of overtaking in conditions when there is a vehicle in the oncoming lane. Also the maximum acceleration of the car given its current load and technical condition is determined; the longitudinal slope of the road is determined; the possibility of safe overtaking the vehicle in front is determined based on the distance travelled over the overtaking time. During overtaking, conformity of the current values of acceleration, speed of the overtaking car and distance to an oncoming vehicle with calculated is monitored and a light and audio signal is emitted to prevent overtaking if there is risk of collision, and also on a dangerous distance to the vehicle in front, based on the slope of the road. ^ EFFECT: group of inventions increase reliability of evaluating safety of overtaking and selecting a safe distance to the vehicle in front by taking into account such additional factors as slope of the road surface, the current and maximum possible acceleration of the car given the current load. ^ 2 cl, 2 dwg
Группа изобретений относится к технике предотвращения столкновений и наездов автомобилей и других транспортных средств (ТС). На автомобиле одновременно принимают оптическое излучение от ТС, находящихся на попутной и встречной полосах движения, преобразовывают их в электрические сигналы, определяют расстояния до ТС, находящихся на попутной и встречной полосах движения, определяют скорости сближения с ними, определяют геометрические размеры ТС, движущегося в попутном направлении. На основе данной информации обеспечивают выдачу световой сигнализации о соблюдении безопасной дистанции до впередиидущего ТС и о возможности выполнения маневра обгона в условиях нахождения ТС на полосе встречного движения. Кроме того, определяют максимально достижимое при текущей загрузке и техническом состоянии ускорение автомобиля, определяют продольный уклон дороги, определяют возможность безопасного обгона впередиидущего ТС до начала его проведения, с учетом проходимого им за в |
