Problems solved by technology

[0005] However, due to cost and volume considerations, the sensors and satellite positioning systems equipped with mobile phones are only at a usable level, and the sensor data and navigation data obtained by mobile phones are not accurate enough.
When users use it, they often cannot find satellite signals (for example, they cannot find satellite signals in tunnels), so they cannot locate the current location, resulting in the inability of the mobile phone to navigate accurately, or even to assist navigation.

Abstract

The embodiment of the invention discloses an aided navigation method and a terminal. The aided navigation method comprises the following steps: if communication connection is detected to be established between the terminal as well as a vehicle-mounted navigation system and a driving data recorder, acquiring navigation data monitored by the vehicle-mounted navigation system by virtue of the terminal, wherein the navigation data comprises location data and sensor data; according to driving images recorded by the driving data recorder and the biosensor data, judging whether the current road condition information meets preset conditions; if the current road condition information meets the preset conditions, starting an inertial navigation mode, and carrying out aided navigation according to the navigation data. The terminal disclosed by the embodiment of the invention can determine accurate travelling track aided navigation according to the navigation data and a driving state and can realize accurate navigation even under the condition that location information can not be acquired.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an auxiliary navigation method and a terminal. Background technique [0002] In daily life, when people are not familiar with the route to the destination or do not understand the road conditions when traveling, they can turn on the vehicle navigation system for navigation so as to reach the destination. [0003] Because the current car navigation system cannot process a large amount of data in real time, offline maps are generally used, and the offline map data is updated slowly and there is no real-time road conditions. As a result, when driving according to the navigation route planned by the car navigation system, people often take the wrong road or have no way to go. [0004] Aiming at the above disadvantages of the vehicle navigation system, a solution proposed in the prior art is to load real-time map data through the mobile phone for navigation. [0005] Howe...
