The invention provides a visual blind zone detection method. The visual blind zone detection method comprises the following steps: arranging ultrasonic distance measuring modules at the two ends of a back bumper and on center pillars of two side doors of a vehicle, and outputting distance measuring signals; performing power amplification on the distance measuring signals through an operational amplifier; converting the distance measuring signals from analog signals into digital signals through an A/D converter; receiving the digital distance measuring signals through a controller, and simulating running tracks of vehicles in a blind zone on a liquid crystal display panel; when a measured distance is smaller than an alarm value, giving out an alarm sound.
