Technology is increasingly present on cars, including in terms of safety, with the introduction of driver assistance systems. Among the most common are those related to the aid in parking or reversing maneuvers, that is the sensors and the 360 ​​° camera, increasingly present as standard in modern cars. But how do these systems work in our car?

 

How parking sensors work

Let’s start with the parking sensors, both front, and rear. The operation is identical in both cases: the sensors emit ultrasonic waves and send them to the control unit. The latter receives them, processes them, and then transmits them to a loudspeaker, to emit intermittent tones with variable intensity and frequency, depending on the distance from the obstacle.

On some cars, there are also bright LEDs, which light up progressively at the distance from the obstacle. By doing so, the driver is able to understand the space available to carry out the maneuver, avoiding hitting another car or an obstacle while parking.

 

How the 360 ​​° camera works

In addition to sensors, many cars have the most advanced 360 ° camera. In addition to the sensors, in fact, this technology uses four wide-angle cameras, positioned at the ends of the car: one on the front grille, two under the rear-view mirrors, and one on the rear. The combined vision and processing of the electronic control unit allow you to have an overview.

The view is offered on the infotainment system screen, where, with the latest evolutions, the car can often also be seen in three-dimensional reproduction and not only from above.
