The invention discloses a reversing blind area monitoring method and system based on an ultrasonic radar, belongs to the field of vehicles, is used for solving the problem that a view blind area exists in a reversing mode of a vehicle through a reversing image or an outside rear-view mirror, and comprises a region division module, a region setting module, a control recording module and an object monitoring module, the area dividing module is used for dividing a view blind area range when a vehicle backs up to obtain six groups of view blind areas, and the area setting module is used for setting reaction duration threshold values of the six groups of view blind areas to obtain reaction duration threshold values of the view blind areas; the control recording module is used for recording the steering condition when the vehicle backs up to obtain a monitoring analysis area when the vehicle backs up, and the object monitoring module is used for monitoring backing obstacles in the monitoring analysis area when the vehicle backs up to generate a backing-up safety signal, a backing-up danger signal or a preset object. According to the invention, all-directional monitoring of the view blind area is realized in the reversing process of the vehicle.
