More than 250 companies worldwide have delved into the self-driving vehicle industry as more people become interested in letting go of the steering wheels. Not all self-driving cars are completely autonomous.

The question is, how do self-driving cars work, and are they safe? Let’s answer this question more in-depth as we look into the ever-growing world of autonomous vehicles. 

How do Self Driving Cars Work?

Before explaining how they work, we need to define what self-driving cars are. 

Autonomous vehicles operate autonomously on the road thanks to hardware and software. The data is gathered by the hardware and organized and compiled by the software.

On the software side, processing the input data typically involves machine learning patterns or intricate lines of code that have been honed in real-world settings. The core of self-driving technology is this machine learning technology.

Self-driving vehicles operate by sensing their environment, navigating around obstructions, obeying traffic rules, and reaching a preselected destination.

They accomplish this task using infrared sensors, GPS, lidar, sonar, radar, and cameras.

Those technologies are positioned strategically across the vehicle. Systems for self-driving cars are powered by AI.

To create systems that can drive independently, self-driving car developers combine huge amounts of information from image recognition systems with neural networks and machine learning.

The algorithms for machine learning are given the patterns that the neural networks found in the information.

Images captured by self-driving car cameras are among the data sources the neural network uses to train itself to recognize objects such as pedestrians, trees, traffic signals, curbside, road signs, and other elements of a given driving environment.

Self-driving Car Example

For instance, Google’s Waymo self-driving car project employs a combination of earlier technologies to recognize everything around the vehicle and forecast what those items may do next.

This takes place in brief intervals of time. These systems must be mature. The system can use deeper learning algorithms to make more sophisticated driving decisions as it accumulates more driving data.

The operation of self-driving cars is described below:

  • The passenger or driver chooses where they want to go. The car’s computer calculates a route
  • A 360-degree rotating Lidar sensor on the roof continuously scans a 60-meter radius around the vehicle to produce a dynamic 3D representation of its surroundings.
  • To determine the car’s location in the 3D map, a rear left tire sensor keeps track of sideways motion
  • Both bumpers’ radar systems measure the distances to obstructions
  • The AI software in the automobile connects to every sensor and gathers data from the Street View as well as internal cameras
  • Using deep learning, the AI mimics human perception and decision-making processes and directs driver control systems like steering and braking
  • To be aware of things like landmarks, traffic signs, and lights in advance, the car’s software consults the GPS
  • Finally, you can take control of the vehicle by engaging the override function, and these are the typical ways when wondering how do self driving cars work.
