- Computer Vision: Self-driving cars use computer vision technology to process visual data. The visual data is captured by cameras. This enables the vehicle to detect and classify objects, read traffic signs, and interpret road markings.
- Control Systems: Self-driving cars have sophisticated control systems. The control systems manage acceleration, braking, and steering. These systems interpret the decisions made by AI algorithms. These systems then translate it to navigate the vehicle safely.
- Connectivity: Self-driving cars rely on wireless communication systems. Connectivity allows vehicles to share information and receive real-time updates, It further enables the improvement in safety and efficiency.
- Redundancy and Safety Features: Self-driving cars use redundant systems and safety features to ensure reliability. It also minimizes the risk of failure. These include backup sensors and redundant computing systems, that can take over control if necessary.
- Human-Machine Interface (HMI): Autonomous cars provide an interface for human passengers as well. The interface allows humans to interact with vehicles. The interaction can be made through touchscreens, voice commands, or other intuitive controls. Humans can input destinations, monitor the vehicle’s status, and intervene when needed.
The features and capabilities of autonomous cars may vary depending on the model, and level of autonomy. Moreover, ongoing advancements are continuously enhancing the features available in self-driving car systems
Levels of Automation
The Society of Automotive Engineers (SAE) has categorized the levels of driving automation in vehicles. This classification is known as the SAE levels of driving automation. It defines six levels that describe the extent of automation in a vehicle’s operation. Here are the SAE levels:
Some level 3 and level 4 autonomous vehicles have been tested and deployed in certain locations. Level 5 fully autonomous vehicles are still in the development stage. These are not yet widely available to the public. The deployment of autonomous vehicles at higher levels is subject to technological advancements.
Autonomous, Automated and Self-driving Vehicles
The terms “autonomous,” “automated,” and “self-driving” are often used interchangeably, but there is a subtle difference between them. Here’s is a generalized definition of these terms:
An autonomous car refers to a vehicle that has the capability to operate and make decisions without human intervention. It can sense and interpret its environment. Moreover, it performs driving tasks independently. The level of autonomy can vary from limited control ( adaptive cruise control) to full control over all aspects of driving ( steering, acceleration, and braking). In general, autonomous cars are capable of adapting to dynamic driving situations. These cars make decisions based on their internal algorithms and sensors.
An automated car is a broader term that incorporates automated systems to assist the driver or perform specific driving tasks. It includes features like adaptive cruise control or automated parking systems. These systems typically require human oversight and are not designed to operate independently in all driving situations.
Self-driving cars can operate without direct human input. These cars are designed to handle all driving tasks. The tasks can be steering and acceleration to braking and decision-making. It can perform these tasks without the need of human intervention.. This allows human passengers to relax or engage in other activities while the vehicle handles all driving responsibilities. The goal of self-driving cars is to provide a fully autonomous driving experience
In summary, “autonomous” generally refers to the vehicle’s ability to operate independently. “Automated” car encompasses a wider range of driving assistance systems. The “Self-driving” car specifically can perform all driving tasks without human intervention.
