How can you use programming languages to create safer autonomous vehicles?

1 Control Engineering Basics

Control engineering is a branch of engineering that deals with the design, analysis, and implementation of systems that can regulate their own behavior according to desired goals and constraints. Control engineering applies mathematical models, algorithms, and feedback loops to monitor and adjust the inputs and outputs of a system, such as sensors, actuators, and controllers. Control engineering can be used to create AVs that can sense their environment, plan their actions, and execute them in a safe and efficient manner.

2 Programming Languages for AVs

Programming languages are essential tools for control engineers to create AVs, enabling them to define the logic, data, and interfaces of their AV system, as well as to test, debug, and optimize it. Depending on the level of abstraction, performance, and compatibility needed, there are many programming languages that can be used for AVs. C/C++ is a low-level language that offers high performance, flexibility, and control over hardware and memory; it is often used for developing embedded systems such as microcontrollers, sensors, and actuators. Python is a high-level language that offers simplicity, readability, and productivity; it is commonly used for prototyping, data analysis, and scripting. MATLAB/Simulink are specialized languages and tools that offer powerful capabilities for modeling, simulation, and analysis of dynamic systems; they are regularly employed for designing, testing, and validating control systems.

3 Safety-Critical Aspects of AVs

AVs are safety-critical systems, meaning any failure or error can have severe consequences for human lives, property, and environment. Therefore, control engineers must consider various safety-critical aspects of AVs, such as fault tolerance, security, and ethics. Fault tolerance can be achieved by using redundancy, diversity, and error detection and correction techniques. Security can be attained through encryption, authentication, and firewall techniques. Adhering to moral principles and values can be accomplished by using ethical frameworks, guidelines, and standards; as well as by involving stakeholders, regulators, and users in the design and evaluation of the system.

4 Best Practices for AV Programming

In order to create safer AVs, control engineers need to adhere to certain best practices when programming. This includes selecting the right programming languages and tools for each task and component of the system, ensuring their compatibility and interoperability. Additionally, code should be modular, reusable, and maintainable; coding standards and conventions should be followed. Version control, documentation, and comments should be used to keep track of code changes and explain the code functionality. Testing, debugging, and verification tools should be used to ensure code quality and correctness, as well as identify and fix bugs. Lastly, simulation, emulation, and experimentation tools should be used to evaluate the code performance and behavior; this allows for comparison and improvement of different solutions and scenarios.

5 Resources for AV Programming

If you are looking to gain more knowledge about programming languages and techniques for AVs, there are plenty of online resources available. Coursera offers various courses and specializations on AVs, such as Introduction to Self-Driving Cars, State Estimation and Localization for Self-Driving Cars, and Sensor Fusion Engineer. Udacity has nanodegrees and projects on AVs, including Self-Driving Car Engineer, Computer Vision, and Robotics Software Engineer. Medium is an online publishing platform that features many articles and blogs on AVs, like How to Code a Self-Driving Car, The Ultimate Guide to Programming Languages for Self-Driving Cars, and Top 10 Programming Languages for Autonomous Vehicles.
