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.
