The invention relates to the technical field of vehicle detectors, and discloses a parking space vehicle detector, which comprises two ultrasonic probes which are independent units and are used for self-transmitting and self-receiving and synchronous and staggered transmission; a microwave probe; and the microwave sensor is used for carrying out self-inspection on the microwave probe. According to the parking space vehicle detector provided by the invention, microwave and ultrasonic sensors are adopted for detection, and the detection is not influenced by the external environment; multi-probe acquisition can effectively reduce the probability of missed detection; the ultrasonic inclined 45-degree design can prevent water from being accumulated in the center of the probe; a probe self-checking function is added, so that whether the probe is damaged can be identified; the ultrasonic receiving circuit adopts an active filter design, so that external interference signals can be effectively reduced.
