The invention relates to a parking space detecting device and method for an automatic parking system. The parking space detecting device comprises a sensor unit, a data processing unit, a buffer, a decision making unit and a correction unit. According to the parking space detecting device and method, a sound pressure sensor is used for detecting parking spaces, sound signals fed back after engine noise and exhaust pipe noise received by the sound pressure sensor are blocked are processed by the data processing unit in real time, longitudinal distance of a target parking space is calculated, whether a vehicle is parked on the parking space or not and whether the longitudinal distance of the parking space meets a requirement or not are judged through the decision making unit and the correction unit, and finally the purpose of automatic parking is achieved. The device and method have the advantage that parking space detection accuracy is further improved through echo detection.
