Abstract : Automotive vehicles are increasingly being equipped with collision avoidance and warning systems for predicting the potential collision with an external object, such as another vehicle or a pedestrian.
Upon detecting a potential collision, such systems typically initiate an action to avoid the collision and/or provide a warning to the vehicle operator.
This system consist of a distance-measuring system based on ultrasonic sound utilizing the PIC 16f877A microcontroller and transmits a burst of ultrasonic sound waves towards the target and then receives the corresponding echo.
An ultrasonic sound sensor is used to detect the arrival of the echo to the system. The time taken for the ultrasonic burst to travel the distance from the system to the subject and back to the system is accurately measured by the microcontroller.
It also provides a warning signal to the driver if the distance between vehicle and obstacle crosses a particular limit. It also monitors the speed of the vehicle and if the speed limit is exceeded it is informed to the driver.
The speed limit for different class of vehicles is set by authorities at different.
