What is a Driverless car?
A Driverless car is a vehicle that is capable of sensing the nearby environment and can operate without human interference. In a self-driving car system, the human passenger is not required to take control of the vehicle at any time. This automated car can go everywhere in a similar way to a conventional car and do everything that an experienced human driver does.
Based on the automation system of cars we can classify driverless cars into the below categories:
As per its name, there is no automation in the car driving system. Inside these cars, control systems are manual or human-controlled. Inside passenger performs all driving tasks like steering, acceleration, braking, nearby environment, etc.
This vehicle features a single automated system. While driving on an open road for a long time, it would be pretty tiring to keep pressing the accelerator pedal. Cruise control is a feature that helps to reduce such fatigue of the driver. Here this control system uses an actuator to control the throttle and helps your car continue cruising at a consistent speed. In older cars, the cruise system was connected to the accelerator through a cable to maintain the hydraulic pedal in a certain position to keep the speed constant. In modern cars, speed is being controlled electronically through a program without any cable. This newer technology can automatically adjust the speed based on how fast the vehicle ahead is going while maintaining a safe distance.
A partial automation system is also known as the Advanced Driver Assistance System (ADAS). By using this system a vehicle can control both steering and accelerating/decelerating. Here the automation falls short of self-driving because the driver can control the car at any time.
There is a higher automation level inside this system as compared to Partial automation. By using this system cars can control a significant number of operations. Here drivers still monitor all tasks and can take control at any time. This automation system has Environmental Detection capabilities and can make informed decisions for them, such as accelerating past a slow-moving vehicle.
The high automation system of the car is advanced than conditional automation. In this automation system, vehicles can intervene if things go wrong or there is a system failure. In simple words, these cars do not require human interaction in most circumstances. Here, the human being has the power to take over the control in this automation.
Vehicles under this category are completely automated and do not require human attention. Complete automation system would not even have steering wheels or acceleration/deceleration pedals. These cars will be free from geo-fencing, able to move anywhere and do any task that an experienced driver can do.
