Imagine a car that drives itself! That’s an autonomous vehicle (AV), also called a self-driving car (SDC). A combination of technologies senses the surroundings and navigates without a human at the wheel. Just as we perceive the world with eyes and ears, and use a map or GPS to find our way, the major parts that will make AVs work are:​

• Sensors: These are like eyes and ears for the car. Cameras, radar, and LiDAR (like radar, but with lasers) work together to create a 3D picture of the road and everything around it.​
• Artificial Intelligence (AI): This is the brain of the AV. It receives information from the sensors and uses complex algorithms to decide what the car should do next, like accelerate, brake, or turn.​
• Software: Think of this as the instructions for the AI. It tells the car how to interpret the sensor data and make safe driving decisions and determine how to find the way to its destination.​

There are different levels of autonomy, for example”, 1) needing a human driver ready to take over (like some advanced driver assistance systems), or 2) a fully self-driving car (still under development), and 3) several levels in between.​

Here is a list of software that is present is today’s Tesla’s

Impacts

Social, Environment, and Cultural Impact: The ubiquity of self-driving cars has the potential to bring about significant changes in society, culture, and the environment. Some of the impacts:​

Technology of Self Driving Cars

​
Dramatic advances in electronics, computing and automation have brought us to where we are today. An Autonomous Vehicle describes something that can operate ​ independently, with no constant ​ outside control. ​

1. Self-Governing:​ An autonomous car has its own set of rules or internal mechanisms that guide its actions. This could be a pre-programmed set of instructions or the ability to learn and adapt based on its environment.​

2. Limited External Control:​ While some external oversight might be present, an autonomous car doesn’t require constant human intervention to operate. It can make its own decisions within its defined parameters.​

3. Levels of Autonomy:​ Autonomy is specified on a scale (Level 0-5). Self-driving cars, for instance, might require some human intervention in complex situations, while a thermostat might operate with very little outside influence.

Society of Automotive Engineers (SAE)

The Society of Automotive Engineers (SAE) provides a standard, “Recommended Practice: Taxonomy and Definitions for Terms Related to Driving Automation Systems for On-Road Motor Vehicles”, commonly referenced as the SAE Levels of Driving Automation™, the industry’s most-cited source for six levels of driving automation. Place holder – TBD​ 

This table provides a quick overview of sensor or sensor-like systems for the car to determine its location, perceive the environment, spaces, and obstacles around the car, and move the car safely along the road. The following slides provide more detail about these technologies.​ 

Sensors

Lidar

Radar

• Detection and Ranging: Radar (Radio Detection and Ranging) uses radio waves to detect objects and measure their distance, speed, and direction. It is crucial for identifying other vehicles, pedestrians, and obstacles in a self-driving car’s surrounding environment.​
• Weather Resilience: Unlike other sensors such as cameras and LiDAR, radar performs well in various weather conditions, including rain, fog, and snow. This makes it a reliable sensor for autonomous vehicles in challenging weather.​
• Doppler Effect Utilization: Radar systems in self-driving cars use the Doppler effect to measure the relative speed of objects. This helps the car understand how fast other vehicles or pedestrians are moving, which is essential for making safe driving decisions.​
• Long-Range Detection: Radar can detect objects at greater distances compared to some other sensor technologies. This long-range capability allows autonomous vehicles to anticipate and respond to potential hazards well in advance, enhancing safety.​
• Integration with Other Sensors: Radar is often used in conjunction with other sensors such as cameras and LiDAR in a sensor fusion approach. This integration provides a more comprehensive understanding of the environment, combining the strengths of each sensor to improve the overall reliability and accuracy of the self-driving system.​

Ultrasonic

• Short-Range Detection: Ultrasonic sensors are highly effective for short-range detection, typically up to a few meters. They are commonly used for parking assistance, detecting obstacles, and low-speed maneuvering in tight spaces.​
• Object Proximity Measurement: These sensors measure the distance to objects by emitting ultrasonic waves and calculating the time it takes for the waves to bounce back after hitting an object. This helps self-driving cars understand the proximity of nearby objects.​
• Weather and Lighting Independence: Ultrasonic sensors are not affected by lighting conditions, making them reliable for operation in both day and night. They are also relatively unaffected by weather conditions such as rain and fog, which can impair other sensors.​
• Cost-Effective: Ultrasonic sensors are relatively inexpensive and easy to integrate into vehicles. This makes them a cost-effective solution for enhancing the situational awareness of self-driving cars, particularly for low-speed applications.​
• Integration with Other Systems: Ultrasonic sensors are often integrated with other sensor systems, such as cameras and radar, to provide a comprehensive understanding of the vehicle’s surroundings. This integration helps improve the accuracy and reliability of obstacle detection and avoidance, particularly in complex environments like parking lots.​

Camera

• Image Recognition: Cameras provide high-resolution images and video feeds that are essential for image recognition and computer vision algorithms. They enable self-driving cars to recognize and classify objects such as traffic signs, pedestrians, lane markings, and other vehicles.​
• Color and Texture Information: Unlike other sensors like LiDAR and radar, cameras capture detailed color and texture information. This is crucial for tasks such as traffic light recognition, reading road signs, and identifying lane markings.​
• Affordability and Ubiquity: Cameras are relatively inexpensive and widely available compared to other sensor technologies. This makes them an attractive option for equipping autonomous vehicles with the necessary sensing capabilities without significantly driving up costs.​
• Close-Range Detection: Cameras excel at detecting objects at close range and providing detailed visual information. This is particularly useful for tasks such as parking, navigating through complex urban environments, and avoiding obstacles.​
• Complementary Sensor Role: In a self-driving car’s sensor suite, cameras complement other sensors like LiDAR and radar. By integrating data from multiple sensors (sensor fusion), cameras help provide a more complete and accurate understanding of the vehicle’s surroundings, enhancing overall safety and performance.​

Software and Algorithms​

Perception and localization are fundamental components in autonomous driving systems, enabling the vehicle to understand its surroundings and position. Perception processes data from various sensors, such as cameras and LiDAR, to detect objects, pedestrians, traffic signs, and road markings. Machine learning and computer vision techniques are employed to classify these elements in real time. Localization, on the other hand, determines the vehicle’s precise location using GPS, inertial measurement units (IMUs), and sensor data. This real-time data is combined with pre-mapped information to provide an accurate understanding of the vehicle’s current position within its environment.

Once the vehicle has a clear sense of its surroundings and location, planning and decision-making algorithms create a safe path to follow. These systems consider the vehicle’s destination and environmental factors, such as nearby objects and traffic, to make real-time decisions like changing lanes or stopping for pedestrians. Control systems then execute these plans by managing steering, acceleration, and braking to ensure smooth movement, adapting to road conditions and the vehicle’s speed. Connectivity further enhances these processes by enabling communication with other vehicles, infrastructure, and pedestrians, sharing real-time data about road conditions. Cloud computing also plays a crucial role, providing additional computational power, enabling software updates, and enhancing the vehicle’s AI-driven decision-making through real-world data and simulations. AI and machine learning systems are integral in refining perception, planning, and control by continuously learning from real-world and simulated experiences.

Human-Machine Interface​

In the world of self-driving cars, the Human-Machine Interface (HMI) acts as a bridge between the automated driving system and the human occupants. It’s essentially a communication system that allows the car to:​

• Inform the driver: The HMI keeps the driver informed about the car’s status, upcoming maneuvers, potential hazards, and the overall driving environment. This might involve visual displays on dashboards or heads-up displays (HUDs), as well as audible alerts or voice messages.​
• Receive driver input: While a self-driving car aims to handle most situations autonomously, there might be scenarios where human intervention is necessary. The HMI provides a way for the driver to take control of the vehicle, disengage self-driving features, or input commands if needed. This could involve buttons on the steering wheel, touchscreens, or voice commands.​

Some key characteristics of a well-designed HMI for self-driving cars:​

• Clarity and Simplicity: The information presented through the HMI should be clear, concise, and easy for the driver to understand. Avoidance of technical jargon and use of intuitive visuals are important.​
• Minimal Distraction: The HMI shouldn’t overload the driver ​
  with unnecessary information or complex interfaces. It ​
  should be designed to minimize distraction while keeping ​
  the driver informed of critical situations.​
• Timely and Accurate Information: The information displayed through the HMI needs to be timely and accurate to allow the driver to make informed decisions when necessary.​
• Trust and Transparency: A good HMI fosters trust between the driver and the self-driving system. It should provide clear indications of the car’s capabilities and limitations, and when human intervention might be required.​
• Adaptability: The HMI should ideally be adaptable to different driving situations and user preferences. For example, it might display more information when the car is in manual mode compared to fully autonomous driving.​

Since self-driving car technology is still evolving, HMI design is an important area of research and development. The goal is to create a seamless and intuitive interface that fosters trust, keeps the driver informed, and ensures a safe and comfortable driving experience.​
