When you are driving or backing up, there are just some obstacles that you can't see from the windshield and mirror, and then, there one more scratch on your car. No one wants to be in a situation like this. To avoid this from happening, we developed a radar system that can be used both as a forward driving collision warning system and a backup radar.
Here is how our system works: the system will be installed in both front and rear bumpers. The one in the front bumper will be used as the forward driving collision system, and the one in the rear bumper will be used as a backup radar. Only one of these systems will be activated based on the gear position. When the distance, measured by ultrasonic ranger, between the car and an obstacle is shorter than a threshold 150 cm, the buzzer will start to make warning noise. As the distance decreases to other thresholds(100 cm, 80 cm, 50 cm, 30 cm), the frequency and pitch of the sound will both increase to further alert the driver.
