Mitsubishi Electric’s autonomous driving system is realized through the use of sensor fusion technology. Peripheral sensors, millimeter-wave radars and cameras, as well as infrastructure auxiliary technology, combine the CLAS signal and high-definition three-dimensional map of the Quasi-Zenith Satellite System. The system can now drive on ground roads, without high-definition maps and automatic parking functions indoors and outdoors, and has been tested in actual environments.

The specific features of xAUTO include:

(1) Local autonomous driving without high-definition maps

The trajectory data is measured by fusing the fusion algorithm with CLAS-based positioning data and other vehicle data (such as speed, yaw rate (lateral movement), etc.), and then these trajectory data are combined into a high-definition local map to match Used in conjunction with the automatic driving system. The system can work in places where there are no high-definition maps, such as residential areas, private roads, farm roads, etc.

(2) Accurate positioning and route arrangement, automatic parking outdoors and indoors

xAUTO’s automatic valet parking system calculates the best driving route to the designated parking space according to the operation plan (parking space, access point, etc.) provided by the control system. When parking outdoors, the system uses CLAS-based positioning to track the calculated route. Indoors, the system uses the camera installed on xAUTO to detect landmarks installed in the parking lot to accurately calculate the location.

(3) Proprietary sensor fusion technology can continuously detect the surrounding area of ​​the vehicle quickly and accurately

Generally, autonomous driving systems require various sensors, such as radars, cameras, and so on. However, since the data processing time and data update cycle will be different according to the data collection of each sensor, if the information with different time is processed at the same time, a recognition error will occur. To solve this problem, Mitsubishi Electric has developed a “sensor fusion technology” that can seamlessly integrate the information of various sensors by adjusting the data output time of each sensor. Therefore, the system can robustly and accurately detect the conditions around the vehicle and the speed of the vehicle.
