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.
