Self-Driving Cars and How Do They Operate?


Over the last few decades, automakers and technological giants have constantly been dumping billions and billions of dollars into researching and making the true accident-free autonomous/self-driving car. It has been a dream for every car maker or car owner nearly as long as the cars came into existence. Getting inside the car, shuffling the songs while a self-correcting and self-driving computer operated car swivels & swerves through the traffic effortlessly that too better than any human driver. Autonomous cars have the power to completely change the world. Google and Tesla are the biggest names in the field of mapping and fabrication of these cars. Google’s confidence in their models of self-driving cars can be inferred from the fact that they’ve taken the steering wheel and even the pedals out altogether in their models, which removes any chance of the driver’s interference with the program or working of the car.

How Do They Work?

Driverless cars or the Autonomous cars on the roads use an array of sensors, real-time 3D maps, radars, cameras and gigabytes of the specialized software to assess and witness (see)  the road ahead of the car, behind the car, and all around every corner of it. Self-driving cars are operated by actuators which are attached to the driving column and pedals. Actuators serve the purpose of translating the constant stream of data incoming from all the corners of the vehicle into the motions of driving. These cars incorporate what the car see into one coherent image, as result making them able to navigate on almost any of the terrains or in any type of weather conditions. In order to feel the surroundings autonomous vehicles make use of technologies and equipment like radar, odometer, lidar, GPS and computer aided vision. Sensory information is interpreted by advanced control systems for the identification of apt navigation paths, obstacles & relevant sign age. Autonomous vehicles have the capability of updating maps of the system on the basis of sensory input, hence allowing the vehicles to stay on track even on entering the uncharted environments. The control systems are capable of planning a path to the desired destination by analyzing the sensory data to differentiate between other vehicles or cars on the road.

The autonomous cars carry with them numerous advantages like:-

  • Traffic collisions which are caused by errors of human driver like reaction time, rubbernecking or distracted & aggressive driving can be avoided.
  • Because of reduced necessity of safety gaps roadway capacity can be improved.
  • These cars will help in the reduction of physical space which is required for parking of the vehicle. Better driving on roads where space availability is scarce.

Apart from all this considering the fact that semi autonomous cars basically rely on a network of safety systems which are always active to work, the safety in these cars if very high. The benefits of these systems like warning of forward-collision have greatly reduced the probability of accidents however when it comes to technology and software there is always a possibility of a system failure even though the probability is very less meaning that you just can’t take a nap behind the wheel.

In today’s world where people long for comfort in everything a smoother ride in self-driving cars is something people will willingly splash their cash for.
