Driving a car is not an easy job. This has been established in many ways through various reports that suggest, humans are not remarkably great at driving. And it was based on this idea, upon which autonomous cars were built.

In today’s rapidly changing time, we all are aware about autonomous cars. Moreover, companies like Google, Tesla, or Baidu have made the world aware about their innovations with regards to autonomous cars. But what is about the autonomous cars that make them what they are? The thing is technology.

Technology components like processing unit, radar, LiDAR, autonomous emergency braking, cameras, sonar, and sophisticated software are part of it.

Processing Unit

An autonomous car has to have a processing unit, which acts like the car’s brain. Self-driving cars take commands from these processing units and all the data and information goes into it. To analyse the data, it has a computing unit which access the data and take decisions accordingly.

Radar

The basic function in of radar in automated cars is to avoid impact from any object by sending a signal to the on-board processor to apply the brakes, or move out of the way when applicable. Radar works in conjunction with other features on the car such as inertial measurement units, gyroscopes, and a wheel encoder in order to send accurate signals to the processing unit of the vehicle in order to better make decisions on how to avoid potential accidents.

LiDAR

Much like radar, a LiDAR also works toward avoiding impact, but it is more associated with the car’s vision. The LiDAR system provides accurate 3D information on the surrounding environment, which enables it to take split-second decisions for self-driving cars. A LiDAR adds more to the car’s safety feature, but at the same time, it’s too expensive that manufacturers sometimes decide to work without it.

Autonomous Emergency Braking

One of the most incredible thing about autonomous car is its emergency braking system. The car system uses radar to detect obstacles, warned drivers, and primed brakes so that they would be more effective when the driver finally used them.

Sonar

Although sonar is more a liability than an asset to the car, its inclusion provides redundancy in the system and allows the car to effectively cross-reference the data in real time, giving it enough time to apply the brakes, pre-tension seat belts for impact, or swerve to avoid obstacles. The limitations of sonar are its narrow field of view and its relatively short effective range.
