Abstract

The invention relates to a vehicle-mounted positioning data integration device and method, and the device comprises an embedded controller, a local storage unit, and a communication module, the inputend of the local storage unit is connected to the embedded controller, the embedded controller is in bidirectional connection with the communication module, and the communication module is also connected to a ground differential base station and a remote control end. The embedded controller is further connected with the wheel speed sensor, the inertial sensor and the GNSS module, receives data from the wheel speed sensor, the inertial sensor, the GNSS module and the communication module, analyzes the received data to obtain vehicle-mounted positioning data, and transmits the vehicle-mounted positioning data to the local memory and the communication module; the communication module is used for transmitting differential data from a ground differential base station to the embedded controllerand transmitting vehicle-mounted positioning data output by the embedded controller to a remote control terminal. Compared with the prior art, local and remote data storage and recording can be achieved, and the method and device have the advantages of being wide in data information source coverage, simple and easy to use.

Description

technical field [0001] The invention relates to the technical field of vehicle positioning, in particular to a vehicle positioning data integration device and a method thereof. Background technique [0002] At present, smart cars have become a major research hotspot in the field of automobiles, and one of the important technologies is vehicle positioning technology. Since a single sensor has its own defects and cannot fully meet the complex and diverse operating conditions of the vehicle, vehicle positioning technology often needs to fuse information from multiple sensors to obtain information such as the speed, position, and attitude of the vehicle. Controlling smart cars provides the necessary data support. [0003] At present, the test of the vehicle positioning system often needs to be carried out on the real vehicle, and the offline analysis is carried out after collecting the information of each sensor separately. However, due to the immature technology of the curren...
