Car Parking Sensors are the proximity sensors that assist the driving force in detecting nearby objects while parking a car. Manufacturers typically install them on the bumpers of a car. Thus, this method is a type of driver assistance system. With the increasing overall dimensions of vehicles and shrinking parking spaces, these sensors are gaining rapid popularity.

1. Front sensors are located on the front bumper.

2. Rear sensors are located on the rear bumper.

1. Reduction in blind spots around the vehicle eases the arduous task of parking in narrow spaces.

2. this technique reduces driver fatigue while parking a vehicle.

3. Improved perception of the realm behind the vehicle reduces the possibilities of injury to the vehicle or other nearby objects.

1. Flat objects or vertical objects of an awfully thin section are difficult to detect.

2. The sensor fails to detect properly if mud or snow holds close to its surface.

These sensors work either on ultrasonic or electromagnetic principles, with the previous being more popular. When the motive force engages reverse gear, rear parking sensors get activated automatically and send ultrasonic waves. When these waves hit the nearby object, they get reflected and are captured again by the sensors. supported the time elapsed between sending and recapturing of waves, ECU calculates the space of the article from the vehicle.

Once the vehicle approaches an object, the system alerts the driving force by an audible tone or signal on the dashboard. because the vehicle advances further towards the article, the intensity of the alarm tone amplifies thereby signaling the motive force to prevent the vehicle. additionally, to those sensors, some vehicle manufacturers also provide cameras to urge a more accurate view of the world behind the vehicle.
