Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] By setting or defaulting a detection range, the present invention detects the surrounding parking lot information points at the current location of the vehicle after the driver arrives at the destination, calculates the straight-line distance between the current location of the vehicle and each surrounding parking lot information points, and judges the straight-line distance Whether it is within the set or default detection range, and finally, guide the driver to one of the parking lots within the detection range.

[0020] refer to figure 1 , the implementation process of the parking lot na...

Abstract

The invention is applicable to the vehicle navigation field, and provides a parking lot navigation method and a system. The method comprises the following steps: detecting peripheral parking lot information points of the current location of a vehicle to acquire the peripheral parking lot map data information; according to the map data information, calculating the distances between peripheral parking lot locations and the current vehicle location one by one, and screening out the parking lot information points within a detection scope; presenting the parking lot attribute information within the detection scope; and guiding the vehicle to a target parking lot according to the presented parking lot attribute information. The method and the system well solve the problem that a driver cannot discover a parking lot because of being unfamiliar to the peripheral facilities of a destination. The method and the system are particularly suitable for the situation that a driver can discover an available parking lot on a busy section of a downtown area or an area where parking lots are hidden.

Description

technical field [0001] The invention belongs to the field of vehicle navigation, in particular to a parking lot navigation method and system. Background technique [0002] As a mature positioning technology, the Global Positioning System (Global Positioning System, GPS) has been widely used in people's production and life fields, among which, the vehicle-mounted GPS navigation system is one of the important application directions of GPS navigation technology. The GPS antenna of the vehicle-mounted GPS navigation system receives the data information transmitted by at least 3 of the 24 GPS satellites around the earth, combined with the electronic map stored in the vehicle-mounted navigation terminal, the position coordinates determined by the GPS satellite signal match this , determine the exact position of the vehicle in the electronic map, and at the same time, display the location, parking orientation, nearby roads and surrounding facilities on the map screen set on the dis...
