Abstract

The invention provides a navigation method and system based on automatic correction drift, a storage medium, and a vehicle-mounted terminal. The method comprises the following steps: according to a starting point, a midway point, and an ending point, acquiring a first navigation path and a second navigation path based on a first electronic map and a second electronic map and carrying out navigation based on the first navigation path; identifying whether a drift track exists in the current navigation path; and if so, carrying out navigation based on the second navigation path. According to theinvention, automatic switching from current electronic map navigation to another electronic map navigation is carried out under the condition of the positioning drift, so that automatic drift correction is realized.

Description

technical field [0001] The invention relates to the technical field of vehicle navigation, in particular to a navigation method and system based on automatic drift correction, a storage medium and a vehicle terminal. Background technique [0002] Car navigation equipment uses car GPS (Global Positioning System) and electronic map for positioning and navigation. It can know the location of the vehicle anytime and anywhere when driving the vehicle, and can tell the driver the shortest or shortest time to the destination conveniently and accurately. fast path. Currently, vehicle navigation devices have been widely used in vehicles. [0003] However, in the actual navigation process, due to reasons such as lack of roads on the map, loss of GPS, and gyroscope failure, etc., often encounter the situation of positioning drift, that is, the positioning is not accurate, or the actual position of the positioning deviates from the actual position. situation, and there is a continuous...
