How can you integrate multiple subsystems in an autonomous vehicle?

由人工智能和领英社区提供技术支持

Autonomous vehicles are complex systems that require the coordination of multiple subsystems, such as perception, planning, control, communication, and power management. How can you integrate these subsystems in a reliable and efficient way? In this article, we will explore some of the challenges and solutions for subsystem integration in autonomous vehicle design.

1 Perception subsystem

The perception subsystem is responsible for sensing the environment and extracting relevant information for navigation, such as road boundaries, traffic signs, obstacles, and other vehicles. The perception subsystem typically consists of various sensors, such as cameras, radars, lidars, and GPS, and algorithms for data fusion, object detection, tracking, and localization. To integrate the perception subsystem, you need to consider the sensor placement, calibration, synchronization, and redundancy, as well as the data processing, storage, and transmission requirements.

2 Planning subsystem

The planning subsystem is responsible for generating feasible and optimal trajectories for the vehicle to follow, based on the perception data, the vehicle state, and the high-level goals. The planning subsystem typically consists of various modules, such as route planning, behavior planning, trajectory planning, and motion planning, and algorithms for optimization, decision making, and risk assessment. To integrate the planning subsystem, you need to consider the trade-off between complexity and performance, the interaction with other vehicles and road users, and the robustness to uncertainty and disturbances.

3 Control subsystem

The control subsystem is responsible for executing the planned trajectories by actuating the vehicle's steering, throttle, and brake. The control subsystem typically consists of various components, such as actuators, sensors, controllers, and feedback loops, and algorithms for stabilization, tracking, and coordination. To integrate the control subsystem, you need to consider the vehicle dynamics, the actuator limitations, the sensor noise, and the control performance and stability.

4 Communication subsystem

The communication subsystem is responsible for exchanging information with other vehicles, infrastructure, and cloud services, such as maps, traffic updates, and emergency alerts. The communication subsystem typically consists of various devices, such as radios, antennas, and modems, and protocols for data encoding, transmission, and reception. To integrate the communication subsystem, you need to consider the communication range, bandwidth, latency, and reliability, as well as the data security and privacy.

5 Power management subsystem

The power management subsystem is responsible for supplying and managing the energy for the vehicle's operation, such as propulsion, sensing, computing, and communication. The power management subsystem typically consists of various elements, such as batteries, converters, inverters, and chargers, and strategies for energy harvesting, storage, and distribution. To integrate the power management subsystem, you need to consider the power demand, supply, and efficiency, as well as the battery life and health.

Integrating multiple subsystems in an autonomous vehicle is a challenging task that requires a holistic and systematic approach. By understanding the functions, components, and interactions of each subsystem, you can design and implement an integrated system that meets the performance, safety, and cost requirements of autonomous vehicle applications.

It’s a very common practice in the industry to make a modular design where each subsystem is assembled separately and can be worked upon as and when required. This is very crucial in increasing the efficiency of the team during testing and validation. The important question that arises is how to make the electrical connections while assembly. Every subassembly must be designed with the harnessing kept in mind and use of connectors such as Deutsch connectors which ensure proper mating. As a mechanical engineer, the design must have proper tolerance for a seamless assembly. One way to do so is through the use of profiles or channels to guide the subassemblies along for a secure connection.

Hacking management system have major role in the autonomous vehicle ,Since it is controlled by controlling center if any deviation in the system may lead to the accident, and malpractice
