Parking system with 4 sensors

parking sensors is proximity sensors for road vehicles designed to alert the driver of obstacles while parking. These Systems use ether electromagnetic ultrasonic sensors.

thesestems feature ultrasonic proximity detectors to measure the distances to nearby objects via sensors in the rear bumper fascias or visually minimized within adjacent or recessses.

the sensors emit acoustic pulses, with a control unit measure the return interval of each reflecting sign and calculating objects.

The System in Turns Warns the Driver with Acoustic Tones, The Frequency Indicing Object Distance, With Faster Tones Indicing Close Proximity and A Continuous Tone Toneing of Minimal Pre-Defined Distance.

rear sensors may be active when reverse gear is selected and deactivated as soon as any gener is selected.

as an ultrasonic system relieves on the reflection of sound waves, the system not detect flat or object insufficient to reflect sound - e.g., a Narrow polle or a longitudinal objctal directy at the vehicle or near an object. Objects with Flat Surfaces Angled from the Vertical May Deflen Sound Waves From the Sension. ALSO SOFT OBJECT WITH STRONG SOUND Absorption May Have Weker Detection, E.G. wool or moss.
