Embodiment Construction

[0016] The present invention proposes a mechanism for quickly and accurately finding a parking space, such as figure 1 Shown is the architecture diagram of the present invention. The parking space detection device 10 is installed on a vehicle. When the driver is ready to find a suitable parking position, the parking space detection device 10 can be activated, which includes an ultrasonic distance sensor 12, a moving distance sensor 14, and a storage unit 16. And a processing unit 18 connected to the above components.

[0017] Wherein, the ultrasonic distance sensor 12 is located at the side of the vehicle, for further understanding of the parking space detection method of the present invention, please refer to figure 1 , figure 2 , figure 2 It is a flowchart of the steps of the present invention. First, step S10 is executed to detect multiple pieces of boundary data, wherein each piece of boundary data includes using the ultrasonic distance sensor 12 to detect the ultras...

Abstract

The invention provides a parking space probing method and a device thereof. The probing method comprises the following steps of: firstly, storing boundary data, such as multiple vehicle moving distances, ultrasonic pass-back distances between a vehicle and a barrier; secondly, judging whether the boundary data fits an estimation condition or not; if probing a state from a space to the barrier or a state from the barrier to the space at first, calculating whether a first differential value between each boundary data and a total mean value of the boundary data is more than a standard difference of the boundary data or not when one state fits; and if so, extracting at least two data points from the corresponding boundary data, namely a first data point and a second data point, so as to calculate the differential value as a weighing value of the first data point and the second data point for allocation, so as to obtain a parking space distance with high accuracy and at least one actual boundary position.

Description

technical field [0001] The present invention relates to a parking space detection method and its device, in particular to a parking space detection that uses ultrasonic waves to detect the distance of a parking space and at least one actual boundary position to improve the accuracy of detecting the actual parking space Method and device thereof. Background technique [0002] With the rapid development of technology and machinery, such as automobiles, as a means of transportation and transportation, the quality of human life has been greatly improved, and it has already played an important and indispensable role. However, the modern society is crowded with people, and the size of the parking space is usually only slightly larger than that of a car. Therefore, when the driver parks, they all rely on their eyes and senses to judge whether the parking space can allow vehicles to park, but such a Judgment method, it is often found that the parking space is insufficient because o...
