#

Working of PCTThe radar system emits invisible high frequency radio waves (Faster than sound).These waves collides the nearest obstacles or objects and bounce back to the sensors.The sensors installed evaluate the distance and time travelled by the signals.


#

Working of PCT (...)The system ECU, on the basis of the gathered information, immediately determines the cars position, speed, distance and relative velocity, if there is potential accident threat or situation and warns the driver about a potential crash or accident.Prepared By: Vishnu Bhadolwala, Sem-7, B.Tech-IV, Enrol No:-20120310131005516/03/2017

Advanced Pre Collision Technology16/03/2017Prepared By: Vishnu Bhadolwala, Sem-7, B.Tech-IV, Enrol No:-201203101310055It employs an infrared camera behind the steering wheel that monitors where your head is at.If your face is turned away from the road when the system detects a potential collision, the Driver Attention Monitor warns you and, if necessary, gently applies the brakes. If a collision is unavoidable, the same PCT measures prepares Brake Assist and tightens the seatbelts.
