The invention discloses an automobile obstacle avoidance method based on millimeter wave radar ranging and STM32 intelligent decision. The millimeter wave radar is used as an efficient data acquisition module, namely the millimeter wave laser radar is used for measuring the distance; sTM32 is used as core processing equipment of an obstacle avoidance algorithm, the obstacle avoidance algorithm and distance detection are executed, and safety judgment is carried out on the obstacle distance; obstacle information detected by the STM32MP157 is displayed on the LCD liquid crystal display screen, and meanwhile, a loudspeaker is used for alarming the distance. The system provided by the invention comprises two main modules: 1) acquiring data of distance to an obstacle by using a millimeter wave radar AWR1642; and 2) the STM32 is used for judging the distance between the vehicle tail and the obstacle according to the distance data, a loudspeaker is driven to give an alarm, and relevant information of the obstacle is displayed on an LCD.
