Abstract

The invention provides a vehicle-mounted integrated navigation method. The vehicle-mounted integrated navigation method comprises the steps of respectively acquiring satellite signal information and vehicle angle changing information; resolving a satellite signal to obtain position and speed information of a current vehicle; obtaining real-time angle speed information by the vehicle angle changing information; and outputting corresponding information to a vehicle-mounted terminal to use. The vehicle-mounted integrated navigation method is characterized by comprising the following steps: acquiring vehicle speed information of a driving computer by an OBD (On-Board Diagnostics) and carrying out comparison and selection on the speed information resolved by the satellite signal and the OBD vehicle speed information; and if the received satellite signal is not good, outputting the OBD vehicle speed information. According to the method, on the basis of not increasing the cost of hardware, the continuity and the reliability of an integrated navigation system are guaranteed to the great extent. Meanwhile, the invention further provides a vehicle-mounted integrated navigation system.

Description

technical field

[0001] The invention relates to the field of satellite navigation, in particular to a vehicle integrated navigation method and a navigation system based on OBD technology. Background technique

[0002] With the improvement of people's living standards, higher requirements are put forward for continuous real-time positioning. However, due to the complexity of the use environment, a single satellite navigation and positioning system is difficult to meet the real-time and continuous positioning needs of vehicles. At present, vehicle-mounted integrated positioning systems mostly use GPS receivers and DR (Dead Reckoning, Dead Reckoning) composed of gyroscopes, vehicle speed pulses or accelerometers for system integration through microprocessors to form GPS / DR combined positioning solutions, but these The schemes have certain limitations. First of all, the use of additional microprocessor chips increases the system cost. Secondly, the DR solution composed of gyros...
