摘要
针对以往车辆防撞雷达报警算法仅处理车辆直道行驶的碰撞距离报警和弯道识别的缺点,建立车辆复杂行驶环境模型。通过车辆安全行驶因素分析,在直道和弯道行驶条件下,判断车辆行驶车道,计算车辆碰撞距离和碰撞时间,提出基于紧张度函数的威胁报警算法。该模型通过仿真达到根据车辆行驶环境分级报警目的,验证了算法的合理性。
Aiming at disadvantageous of automotive anti-collision alarm algorithm only involving range and roadway judgement in curve road, a new model of vehicle safety was established. Through the analysis of vehicle safety under straight and curve road, roadway judgement of aim-car,distance-to-collision and time-to-collision was getted, a new algorithm of alarm based on tensity was presented. The emulation results showed that classification alarm can be achieved by the new algorithm.
