Parking Assist System

Parking Assist System is a system with sensors that are mounted on a vehicle to alert the driver of any obstacle while driving or parking.

This technology is based on the usage of two types of signals: ultrasonic or electromagnetic signals.

These systems that use ultrasonic signals have ultrasonic proximity detectors integrated into sensors that are mounted on the bumper fascias(rear /front) and measure the distances to surrounding objects.

The acoustic pulses are measured with a control unit on the return interval of each signal that is reflected.

This way the distances to the objects in the environment are measured and calculated and acoustic tones are used to warn the driver.

The different frequencies of the acoustic tones indicate how near or far the object is, faster tones for proximity and continuous for a predefined minimum distance.

These systems have included LCD readouts or even vehicle pictogram displayed on the infotainment screen to allow visualization of objects as colored blocks.

When the reverse gear is selected the rear sensors are activated to enable you to park safely, even rear back-up camera can be used to visualize the rear part of the vehicle.

Ultrasonic parking systems use sound wave reflection and have some minor lacks because some small or flat objects that do not reflect sound can be missed and provoke damage to the vehicle.

To eliminate any blind spots electromagnetic parking sensors were introduced. This kind of sensors uses back-up cameras also and assure visualization of objects along with the acoustic signals.

Extra options as blind spot sensors and cross-traffic alerts are often included making even more effective the parking assist system.
