3.1 Introduction to Autonomous Cars Autonomous cars, also known as driverless cars, or self-driving cars are vehicles that can drive themselves without a human driver to control the steering, acceleration, and braking (Thrun, 2010). They are designed to sense their surroundings with techniques of artificial intelligence, sensors with a 360° of view, radar, and global positioning systems, so that the driver is not expected to constantly monitor the roadway while operating in self-driving mode. Advanced control systems analyze the sensory information gathered to plan the best route to the desired destination. Obstacles and road signs are all part of the algorithm to be taken into account ahead of time. In addition, the autonomous vehicles…show more content…
Level 2 Combined Function This level involves automation of at least two primary control functions designed to work in unison to relieve the driver of control of those functions. An example is adaptive cruise control in combination with lane centering. Level 3 Limited Self-Driving Vehicles at this level of automation are able to operate autonomously for some portions of the journey. Transfer of control back to the human driver happens with some warning. The Google car is an example of limited self-driving automation. Level 4 Full Self-Driving The vehicle is designed to perform all safety-critical driving functions and monitor roadway conditions for an entire trip without manual control at any time during the trip. 3.2 Advantages And Limits There are many potential advantages to using a driverless car instead of a traditional human-controlled vehicle: Reduction in car accidents. Most car accidents are caused by driver errors, but the autonomous system can monitor a broader range of sensors and react faster than a human driver. More efficient transportation due to higher speed limit Increase in road capacity and reduction in traffic congestion due to narrowed safety gap and intelligent parking technology. Occupants in an autonomous car will not be constrained due to age, license, disabilities, intoxication and other factors. Although we can benefit from the self-driving cars, potential
