The invention discloses an automobile blind area detection alarm method and system. The method comprises steps of S1, judging an automobile driving mode according to the speed Vo, steering wheel angleand yaw velocity of an automobile, and then executing S2; S2, determining an alarm area according to the vehicle driving mode and the vehicle driving speed Vo, and then executing S3; S3, judging whether a target enters an alarm area or not, if so, executing the step S4, and otherwise, ending; S4, judging whether the target has a historical tracking track or not, if so, executing the step S6, andotherwise, executing the step S5; S5, judging whether the target meets a secondary screening condition or not, if so, executing the step S6, and otherwise, returning to execute the step S3; S6, judging whether the duration time of the target in the alarm area exceeds a preset first time threshold value or not, if so, performing target alarm, and then ending, otherwise, returning to execute S3. According to the method, the false alarm rate under the environment where false alarm is easy to occur, such as static guardrails and enclosing walls, can be reduced.

    本发明公开了一种汽车盲区检测报警方法及系统,该方法包括:S1、根据车辆行驶的车速Vo、方向盘转角、横摆角速度,判断车辆行驶模式,然后执行S2;S2、根据车辆行驶模式和车辆行驶的车速Vo,确定报警区域,然后执行S3;S3、判断是否有目标进入报警区域,如果是,则执行S4,否则结束;S4、判断目标是否有历史跟踪轨迹,如果是,则执行S6,否则执行S5;S5、判断目标是否满足二次筛选条件,如果是,则执行S6,否则返回执行S3;S6、判断目标在报警区域持续时间是否超过预设的第一时间阈值,如果是,则进行目标报警,然后结束,否则返回执行S3。本发明能降低在静止的护栏、围墙等容易产生误报警的环境下的误报警率。
