The invention provides a parking space identification simulation method based on an ultrasonic technology, and the method comprises the steps: configuring a simulation vehicle and an ultrasonic sensor, and building a parking space environment scene; establishing a communication mode between the simulation vehicle and the parking space identification system; enabling the simulation vehicle to advance in the environment scene, and carrying out the parking space recognition through a parking space recognition system; comprising the steps of establishing a coordinate system according to an initial position of a simulation vehicle, and determining vehicle body coordinate data; opening up a queue, acquiring ultrasonic data every certain distance during the driving of the simulation vehicle, and storing the ultrasonic data into the queue; taking two adjacent data of the queue and the advancing distance of the simulation vehicle to perform triangular judgment, and drawing an obstacle contour; a jump edge in the queue is identified in a jump identification mode, and coordinates of a jump point are recorded; and judging whether the transverse and longitudinal distances of the two adjacent jump points meet the parking space requirement of the simulated vehicle or not. According to the invention, the parking space contour can be drawn, and the accuracy and precision of parking space identification are improved.
