What is a driverless car ?
It is a vehicle that can drive itself from one point to another without assistance from a driver; in other words, with an autopilot system
How will the car detect the traffic lights ?
A sensor “actinometer “ is used to detect the intensity of radiation
Light of different colors will radiate different -2-intensity of radiation
Which will be detected by the sensor
If the detected intensity is of red colour or yellow colour then controller will send a command to stop the vehicle .
The command will be followed by robot(to convert the computer command into mechanical input)
Automatic Braking
Senses an imminent distance with another vehicle or a velocity related danger.
Responds by either precharging the brakes or by applying the brakes to slow the vehicle without any driver input.
Detects by radar, video, infrared, ultrasonic, GPS sensors.
