Right-turn anti-collision three-level early-warning system and method for intelligent vehicles

Abstract

The invention discloses a right-turn anti-collision three-level early-warning system for intelligent vehicles. The intelligent vehicle right-turn anti-collision three-level early-warning system comprises a data acquisition system, a calculation simulation system and a three-level early-warning system, wherein the data acquisition system is used for acquiring the speed and motion posture information of an own vehicle, the positions and speeds of other vehicles, as well as the positions, speeds and motion postures of pedestrians; the calculation simulation system is used for recognizing a right-turn working condition, calculating the collision probability and drawing a collision probability curve; and the three-level early-warning system is used for drawing a three-level early-warning graph,judging the early-warning level through an early-warning area and a collision probability curve, and sending an alarm. According to the right-turn anti-collision three-level early-warning system forintelligent vehicles, driver information is fed back through the three-level early-warning system in order to lower the collision probability, so that the security of the intelligent vehicle in turning at intersections is improved, and the aim of protecting the vehicles and pedestrians is fulfilled.

Description

technical field [0001] The invention relates to the field of intelligent vehicle technology and intelligent vehicle collision probability calculation and early warning system design, in particular to a right-turn anti-collision three-level early warning system and early warning method for intelligent vehicles. Background technique [0002] The intelligent vehicle safety system continues to develop with technological progress. The turning condition of intelligent vehicles at intersections is a complex traffic scene with a high incidence of accidents. Therefore, it is necessary to reduce the collision probability through technical means. Among the many traffic accidents, collisions between pedestrians, vehicles and turning cars are more and more common in urban conditions. At present, there are many researches on collision warning and active collision avoidance, but many researchers have not considered the collision caused by turning cars at intersections. Research at home an...

Problems solved by technology

In terms of turning collisions, some scholars have optimized the design of intersections from the perspective of transportation to reduce the probability of collisions between large vehicles turning right and pedestrians, but they cannot accurately cover all possible collisions in turning conditions.
