- Environmental Perception
Multi-sensor cooperative sensing and fusion technologies are studied to achieve the key information collection and knowledge extraction for autonomous vehicles, which include the detection and identification of drivable areas, lane lines, traffic signs, traffic lights, other vehicles, people and obstacles as well as the prediction ofposition and motion. Our technology exploits an appropriate multi-sensor layout to fulfill the 360-degree coverage and the enhanced coverage effect for key areas. Moreover, we also design a software system with safety redundancy design to ensurethe accuracy of surroundings perception and eventually achieve the safety and stability of driving.
- High-precision Localization
High-precision intelligent localization based on high-precision maps and exactmappings between physical world and digital world will provide the accurate traffic elements, POI, and other surrounding information for autonomous vehicles. Thus, we study the new positioning technology of multi-source fusion in the cloud, build up the cloud platform for information fusion and processing, and eventually establish a dynamic location network to connect “vehicle to human” and “vehicle to vehicle”. This network not only provides the location services for autonomous driving, but also supports the data collection and backhaul with accurate location to online update the high-precision maps, which dramatically improves the accuracy, reliability, and intelligence of the localization system.
- Decision and Planning
The studies on decision and planning can be divided into two parts: driving decision-making system and motion planning system. The driving decision-making system is to explore the nature mechanism of human’s driving behaviors, train the optimal behavior model and parameters, and optimize the online driving behavior through the analysis of high volume real-life high-precision traffic data. Moreover, with consideration of the limited computing resource, the motion planning system is to search thousands of possible trajectories to choose the best one based on the surrounding environment information, which achieves better and more steady driving experience.
- Smart Control
Smart control consists of horizontal control and vertical control. Horizontal control helps to improve autonomous vehicles’ path tracking ability, i.e., control the vehicles to safely and steadily drive along the planned way. On the other hand, vertical control manages autonomous vehicles’ speed tracking ability to let them cruise at the predefined speed.
- Autonomous Driving Simulation Platform
The simulation platform consists of four parts:（1）Traffic intelligent system is to extract realistic behavioral models from large traffic data, and simulate the behaviors of vehicles, pedestrians and other objects.（2）Scene editing and generation system is to edit various extreme scenarios and generate the similar scenarios, which can fulfill the stress test on the autonomous driving algorithm.（3）Rendering system for virtual world is to visualize the simulated scenarios and improve the intuitive feeling of problem analysis.（4）Large-scale server deployment system targets on improving the scalability and efficiency of simulation, which can fulfill the simulation test for hundreds of millions of kilometers per year.
The simulation platform enables to save huge time and cost on autonomous driving test and greatly reduce the test risks. It can randomly simulate various extreme scenarios and cover all the tests.
- Data Platform
Data platform collects abundant data for perception to improve the robustness of autonomous driving. Our studies focus on the following aspects:（1）how to build an efficient labeling system to reduce the labeling cost and improve the labeling efficiency and accuracy;（2）how to effectively monitor the vehicle’ status and problem and how to appropriately visualize the data.（3）how to combine the actual data and simulated data. The objective is to provide the integration and index of structured, semi-structured, and unstructured data.
- Cooperative Vehicle-Infrastructure Systems (CVIS)
Cooperative vehicle-infrastructure system constructs a new model of “vehicle-road-cloud”. Thus, we target to study the frontier road technologies, i.e., multi-sensor perception, multi-modal data fusion and processing, low power edge computing and direct communications for medium and short range, as well as implement a brand-new intelligent device to provide the real-time data services for vehicles and offer the traffic information for the cloud.
- Intelligent Driving
Autonomous Driving Lab participates in the construction of national intelligent logistics backbone networks. It works on building a huge logistics network to connect different cities and various in-transit warehouses and maximizing the utilization of road resource at different time periods, which eventually facilitates the smart, accurate, fast, safe, and green circulation and delivery for goods.
