Parking sensors are a technology that allows the driver of an automobile, truck, or commercial vehicle to be alerted to nearby objects in their path. Parking sensors are also known as backup sensors, parking sonar or just sonar depending on the automaker. While there are variations in the design and features of these systems, the basic design puts sensors in the vehicle's bumper or on brackets. These sensors send ultrasonic waves at 40,000 times per second that detect obstacles behind the vehicle. A controller installed inside the vehicle then receives the signal from the sensors and transmits it to a speaker that emits a tone, or to a combination speaker and display unit. As it results, the first invention of ultrasonic Parking sensors has been invented in Italy by electronic Engineer Massimo Ciccarello and Professor Architect Ruggero Lenci.

But I think, this technology is quite expensive and not for every kind of people.

There are two common types of reverse parking-assist systems. The first is a simple audio warning indicating that the vehicle is approaching an object out of view. The second is a sophisticated camera and video-monitoring system that provide the driver with a view of the blind spot. Both types are available as options on new vehicles and from aftermarket providers. They can easily be installed in nearly any type of vehicle, regardless of the vehicle’s age. commercialfleetproducts.com
