Google Car Technology and How Automatic Car Works
Google propelled in the market another innovation self-driven Google Waymo Car, mean Autonomous Car OR Google Car.Google Vehicle auto could be worked without driver self-governing auto.This is automation google technology, application of Robotics and Artificial Intelligence (Google Car). As an advantage, Reducing road accidents, congestion, fuel, and power consumption is very low as well as respect all traffic law.This is about Self Driving Cars Articles.
Components & Working Principle of the Autonomous Waymo Car:-
Google Driverless Vehicle / Waymo Car / Google Self Driving Cars Articles / Working principle of the Google Self Driving Vehicle: Automation Technology
Before studying the operation of the car, we would need to study Sensor Science and Technology.
Global Positioning System GPS detects the physical geographical position Latitude, Longitude & Altitude by fetching reading from the tachometer, altimeter, and gyroscope.GPS device combines all reading and provides as possible as the accurate measurement of Latitude, Longitude & Altitude of the Google Waymo Car. This is the start of the Self Driving Cars Articles.
Ultrasonic Sensor provides an easy method of distance measurement. This sensor is ideal precisely for any number of utilization that needs you to perform estimations between moving or/and stationary items.An input ultrasonic burst (good enough for human hearing) is to be applied by triggering and generated echo return back in pulse form.The time required for echo return back and velocity of echo is measured distance value by multiplication. The ultrasonic sensor measures the position of an object very close to the car. This device throws an ultrasonic wave to the object. Ultrasonic Sensors measures echo reflect back velocity and time. Hence, Distance between car and object is to be determined by meter box that is calibrated in terms of distance.Ultrasonic sensors may be used to measure the position of objects very closed to the vehicle, such as curbs and other vehicles when parking, the essential part of the Autonomous Car.
Odometry Sensors is the use of data from motion sensors to determine the change of position of google car with respect to time. Mean Odometry Sensor is used for motion estimates such as displacement, velocity, acceleration, and retardation of the car with respect to time. Odometry Sensor is connected by a few robots, it is possible that they are legged or wheeled, to gauge around (not decide) their position with respect to a beginning stage area. This measurement method is sensitive to errors.Accurate and speedy data collection, equipment calibration and processing are required for effective applications, the essential part of the Autonomous Car.
Central Computer: Central computer lies at the central position of the car.Almost all peripherals are attached to the central computer.Centralized computer act as the heart of Google self-driving car by controlling physically connected peripherals directly.Some peripherals are to be controlled indirectly by centralized computer those are not physically connected directly. The data from all sensors is broke down by the local PC that controls the directing, quickening agent, and brakes.Its software must understand the rules of roads, both formal and informal, the control part of the Autonomous Car.
Lidar Sensors also well known as LIDAR, LiDAR or LADAR is a measurement technology which measures the distance between two objects by illuminating a laser light. It measures distance by illuminating a laser light on a target moving or/and stationary object(s). Lidar is an acronym of Light Detection And Ranging and it was originally created as a package of “light” and “radar”.It is also known as surveying technology. It measures, monitors the distance between the car and surrounding road, vehicle, pedestrian etc by illuminating laser light. Lidar sensors bounce pulses of lights off the surroundings. These are analyzed to identify lane markings and the edges of roads.
Radar Sensor is an object-detection device which uses radio waves or microwaves to determine the properties (such as range, angle, or velocity, acceleration) of the target object(s).Applicable field area of such system detects aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A Radar transmits radio waves or microwaves that make collision with the target object and reflect back in the same path. A receive radar that is typically the same system as the transmitting radar.The properties of the target object could be determined by receives, analyzing and processes these reflected waves. Radar Sensor is an object detection system that transmits radio waves to the object like road, other vehicle and pedestrian etc.Radar sensor receives the reflected wave from objects to determine properties of the objects like road, vehicle, pedestrian etc. The radar sensor detects and monitors the position of other vehicles nearby surrounding. Such sensors are already used in adaptive cruise-control systems.
Video camera detects and monitors nearby surrounding object(s) of the car.Video camera detect traffic light, read road sign(s), keep track of the position of another vehicle(s) and look out for pedestrian(s) and obstacle(s) on the road.This is the vital characteristics of the google car.
