Problems solved by technology

But now there are more and more large-scale comprehensive commercial centers, and large-scale comprehensive commercial centers often include multi-storey parking garages. When vehicles are parked in such indoor parking garages, the GPS signal is not seriously hindered, and the vehicle can only be obtained through GPS. The approximate location of the parking position, but it is very difficult to accurately find a parking vehicle in a multi-storey parking garage with complex guides

Embodiment 1

[0013]In this embodiment, the device binding inertial guidance method is made, the principle is based on the pre-set reference point, based on the relative displacement of the user car with respect to the reference point, is calculated to calculate the position relative to the reference point. Specifically, it is located in two positions including A and B, and the B point is 20m in the orientation of the A point, and the driving method from the A point is from the reference point A, 20 meters to the east, and then north Displacement 10 meters and reaches the B point.

[0014]In practical applications, driving vehicles depart from A, record path data such as each line displacement of each line displacement, and until the point B. When the funker gets the path data, it will be started from the A point, and when the path data is found to stop in the B point. However, it will be apparent, due to the accuracy of the data, the farther distance of the B point distance A, the accumulation of t...

Abstract

An inertial guidance road guiding method based on equipment binding is provided by the invention, and can be realized according to a vehicle driving path without positioning cooperation of a GPS (Global Positioning System) or other external electronic equipment. According to the method, the navigation problem caused by the fact that GPS signals are shielded is avoided, other physical or electronic markers do not need to be added in a parking garage, natural unique signboard information with a plurality of parked vehicles in a parking lot is used as a base point, and the length of the road based on inertial guidance is divided, so the road based on inertial guidance is more accurate, and the problem that a car seeker seeks a car in a large-scale parking garage is solved.

Description

Technical field[0001]The present invention relates to a position navigation method based on a reference point and an inertia, particularly an inertial guiding guide method based on device binding.Background technique[0002]With the increasing amount of electric vehicles, some new energy vehicles have also begun to introduce the operational model of the power transmission. However, during the exchange, the service personnel find the efficiency of the user's vehicle is one of the key factors of the success of the user experience. When the vehicle is moored in the empty area, the GPS signal is not obscured, and the vehicle can be accurately positioned. However, there are now more and more large integrated business centers, while large integrated business centers often contain multi-storey parking garages. When the vehicle is moored in such an indoor parking garage, there is no GPS signal to be seriously hindered, only GPS can be obtained from the vehicle The parking position is substant...
