Against the backdrop of the global exploration of intelligent transportation and the advocacy of green travel, Easy Semiconductor Technology (Hong Kong) Limited, with its keen market insight and profound technical expertise, has dedicated itself to the research and development (R&D) of autonomous buses, aiming to bring revolutionary changes to urban public transportation.

I. Technical Core - In - depth Application of Radar QT128

The company has selected Hesai Technology's near - range ultra - wide - angle LiDAR QT128 as the key sensing device, serving as the "eyes" for precise perception of autonomous buses. The QT128 boasts numerous outstanding features. Its ultra - wide vertical field of view (FoV) of 105° is the best among similar products. Through a reasonable tilting installation method, it can comprehensively cover the blind spots around the vehicle body. Whether it is low - lying obstacles such as road cones and scurrying small animals, or elevated objects like multi - storey car parks and high - rise buildings, the radar can identify them clearly, providing the vehicle with a seamless environmental perception.

This radar is equipped with 128 vertical lines, which doubles the number compared to the previous generation architecture. Thanks to its unique line distribution design, the minimum horizontal and vertical resolutions in the encrypted area of the QT128 both reach 0.4 degrees, approaching the resolution level of long - range main radars. Even the dynamic movement of an object as small as a table tennis ball can be accurately detected, greatly enhancing the ability to perceive the details of road objects. Meanwhile, the QT128 has increased effective reflectivity information compared to its predecessors, with a high level of accuracy. This significantly improves the recognition and classification capabilities for lane lines, road signs, and various objects, providing more abundant and accurate data support for the vehicle's decision - making system. From design to verification, the QT128 strictly adheres to the automotive - grade product development process, and its reliability tests are carried out in accordance with top - tier OEM standards. This ensures that it can operate stably and reliably in the complex and changeable operating environment of buses, guaranteeing the safety of vehicle operation.

II. Project Progress - Completion of the Test Vehicle

After the tireless efforts of the R&D team, the project's test vehicle has been successfully completed. The test vehicle integrates an advanced sensing system with the QT128 radar at its core, coupled with high - precision positioning modules, intelligent decision - making algorithms, and efficient communication units. In terms of vehicle body design, passenger comfort and safety have been fully considered. The interior space is spacious, the seat layout is reasonable, and it is equipped with complete safety handrails and emergency braking devices.

During the previous R&D process, the R&D personnel carried out a large number of adaptation and debugging works for the QT128 radar, optimizing the data interaction process between it and other vehicle systems to ensure the timeliness and accuracy of data transmission. At the same time, by simulating various complex road conditions, the vehicle's intelligent decision - making algorithms have been repeatedly trained and optimized, enabling the vehicle to quickly and accurately make driving decisions such as accelerating, decelerating, and turning based on the data collected by the QT128 radar and other sensors.

The completion of the test vehicle marks the project's entry into the crucial field - testing stage. Next, Easy Semiconductor Technology (Hong Kong) Limited will conduct multi - scenario and high - intensity tests on the vehicle in a specific closed - test site. These tests will cover operation under different weather conditions and road environments, comprehensively inspecting the vehicle's performance, with a particular focus on evaluating the perception effect and stability of the QT128 radar in real - world scenarios. Once the closed - site tests meet the standards, the vehicle will gradually be promoted to open - road actual operation tests. Real - world operation data will be collected to continuously improve the vehicle's performance, laying a solid foundation for the commercial operation of autonomous buses and helping urban public transportation in Hong Kong and even globally to move towards an intelligent, efficient, and green new era.
