Vehicle-mounted intelligent parking guidance system

Abstract

The invention discloses a vehicle-mounted intelligent parking guidance system which consists of a vehicle-mounted navigation unit and several wireless devices for transmitting the information of parking lots, wherein first wireless communication modules transmit the coordinates of the parking lots and the numbers of vacant parking spaces through 2.4G common communication channels, a GPS (Global Positioning System) module obtains the coordinate of the vehicle and then transmits the coordinate to a second microprocessor, a second wireless communication module receives the coordinates of the parking lots and the numbers of the vacant parking spaces transmitted by the first wireless communication modules, the second microprocessor compares the coordinate of the vehicle with the coordinates of the parking lots to calculate the distance from the vehicle to each of the parking lots, and the second microprocessor optimizes the distance to each parking lot and the vacant parking spaces, and predicts and dynamically optimizes the relative bearing of the parking lot. The vehicle-mounted intelligent parking guidance system is capable of conveniently, rapidly and flexibly guiding a driver to search a parking lot so as to conveniently and rapidly park the vehicle in an unfamiliar road network.

Description

technical field [0001] The invention relates to the fields of embedded technology, wireless communication technology, GPS positioning technology, optimal search technology and the like. Using the synthesis and integration of multiple technologies, it is applied in the field of transportation to solve the static traffic problem in intelligent transportation, specifically involving a vehicle-mounted intelligent parking guidance system. Background technique [0002] In recent years, my country's automobile industry has developed rapidly. In 2009, my country's automobile production and sales have jumped to the first place in the world. More and more urban families have private cars, resulting in increasing urban traffic flow. "Parking difficulty" has become a very difficult problem, seriously affecting the traffic environment and residents' lives, and restricting the development of the city. However, the construction speed of parking lots in my country is far behind the growt...

AI Technical Summary

Problems solved by technology

[0004] The traditional parking guidance system needs to build a large number of LED electronic displays on both sides of the road, which not only has high construction and maintenance costs, but also affects the appearance of the city; drivers will also be distracted when observing the LED displays; Difficult to get parking information

For drivers who are not familiar with road conditions, sometimes it is difficult to find a suitable parking lot in the intricate road network under the limited three-level guidance mode even if they see the LED display
