Vehicle-mounted inertial navigation system

Abstract

The invention relates to the technical field of vehicle-mounted systems and provides a vehicle-mounted inertial navigation system to overcome the technical problem of poor navigation experience of conventional vehicle-mounted navigation systems. The vehicle-mounted inertial navigation system comprises a data acquisition module, a data processing module and a data output module, wherein the data acquisition module comprises a pressure altitude sensor, an acceleration sensor, an image acquisition module and a mileometer; the data processing module comprises a one-chip microcomputer, a signal processing unit, a USB interface, an interruption response module, an I2C bus interface module and a serial port communication interface module; the one-chip microcomputer is connected with the signal processing unit; the signal processing unit is connected with the USB interface; the data output module comprises a communication module and a display module; the pressure altitude sensor is connected with the I2C bus interface module; the acquisition module and the data processing module are connected with the data output module through data lines via the USB interface; the mileometer is connected with the interruption response module; and the communication module and the display module are connected with the serial port communication interface module. Thus, navigation experience of three-dimensional location is provided.

Description

technical field [0001] The invention relates to the technical field of vehicle systems, in particular to a vehicle inertial navigation system. Background technique [0002] With the rapid growth of China's economy, the number of cars in China is increasing at a rate of millions every year, and cars have entered thousands of households. There are more and more functions in the car, which can independently locate the current position and provide navigation for users, etc. However, the existing navigation devices are not very flexible, especially on bridges with a certain height, the height cannot be detected information, and functions such as navigation and positioning cannot be continued when the signal is weak, so the navigation experience is poor. Contents of the invention [0003] The embodiment of the present invention solves the technical problem of poor navigation experience of the vehicle navigation system in the prior art by providing a vehicle inertial navigation ...
