DEVICE FOR MONITORING OF SAFE DISTANCE BETWEEN VEHICLES Russian patent published in 2000 - IPC

FIELD: car equipment. SUBSTANCE: device has serial circuit of detector and pulse generator, oscillator, two counters, solving unit, which output is connected to input of signaling unit, two lenses, second detector, frequency divider, two memory registers, second pulse generator. Each detector is designed as linear charge-coupled device, which has n photosensitive cells, which are aligned in one line. It is located in back focal plane of respective lens. Optical axes of lenses are separated by base distance L and oriented in parallel to movement of car which carries equipment. Output of each linear charge-coupled device is connected through respective pulse generator to counting control input of each counter, which output is connected to respective input of solving unit through respective memory register, which information input is connected through frequency divider to output of oscillator in parallel to control input of each linear charge-coupled device and information input of each counter. Oscillator is designed as shift pulse generator. Solving unit is designed as distance calculation unit using data about direction of arrival of detected emission. EFFECT: possibility to conduct measurement in arbitrary road situation, increased precision of measurement for poor visibility conditions. 1 dwg
