PARKING GUIDANCE DEVICE AND METHOD THEREOF
First Claim
1. A parking guidance device, adapted for mounted on a car to be used as parking assistant while having information relating to the length and width of the car to be stored therein, comprising:
- a central controller;
a distance detector, electrically connecting to said central controller for detecting distances between obstacles surrounding the car;
an image detector, electrically connecting to the central controller for detecting the shape of a parking space;
a two-axis rotating detector, electrically connecting to the central controller for detecting information relating to the locality of the car;
a human-machine operation interface, electrically connecting to the central controller for inputting signals; and
a car controller area network bus interface, electrically connecting to the central controller for controlling the wheel, engine and braking system of the car;
wherein, the central controller integrates the information of distances and shape of the parking space while comparing the integrated information with the information of length and width of the car as well as it locality information so as to gain a parking track, and then directs the car to move in a moving track conforming to the parking track by controlling the wheel, engine and braking system through the car controller area network bus interface.

Abstract
A parking guidance device storing the information of length and width of a car is disclosed, which comprises: a central controller, a distance detector electrically connecting to said central controller for detecting the distances from obstacles, an image detector electrically connecting to said central controller for detecting the shape of a parking space, a two-axis rotating detector electrically connecting to said central controller for detecting the direction of said car, a human-machine operation interface electrically connecting to said central controller for inputting signals, and a car controller area network bus interface electrically connecting to said central controller for controlling wheel, engine and braking system, wherein said central controller integrates the information of distances and shape of said parking space, compares the same to the information of length and width of said car to gain a parking track, and makes the moving track of said car correspond with said parking track by controlling wheel, engine and braking system through the car controller area network bus interface.

13. A parking guidance method, comprising the steps of:
-
(a) providing a parking guidance device, being comprised of a central control, a distance detector, an image detector, a two-axis rotating detector, a human-machine operation interface, and a car controller area network bus interface, being electrically connected to the central control in respective; (b) activating the parking guidance device for enabling the two-axis rotating detector to acquire information relating to the locality of a car; (c) using an image detector to detect images from the two lateral sides of the car while using a distance detector to detect distances measured between obstacles located at the two lateral sides of the car; (d) enabling a central controller to make an evaluation by the use of the obtained images for determining whether there is a parking space available for parking;
if so, the flow proceeds to step (e);
otherwise, the flow proceeds back to step (c);(e) enabling the central controller to make an evaluation for determining whether the size of the available parking space is larger than that of the car;
if so, the flow proceeds to step (f);
otherwise, the flow proceeds to step (c);(f) enabling the central controller to generate a relative position information between the car and the parking space according to the distances measured between obstacles surrounding the car and the locality information of the car; (g) enabling the central controller to perform a calculation for gaining a parking track according to the relative position information; and (h) enabling the central controller to direct the car to move in a moving track conforming to the parking track by controlling the wheel, engine and braking system through the car controller area network bus interface. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
