These sensors help the driver detect obstacles early while parking and avoid collisions.<\/p>\n\n\n\n<p class=\" translation-block\">In a classic <strong>parking assistance system with parking sensors<\/strong>, there are usually <strong>four sensors in the rear bumper<\/strong>. In more advanced systems, <strong>additional sensors can also be installed at the front<\/strong>, allowing obstacles to be detected both when moving forward and when reversing.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">How parking sensors work<\/h4>\n\n\n\n<p class=\" translation-block\">The sensors continuously emit <strong>ultrasonic pulses<\/strong>. As soon as these sound waves hit an obstacle\u2014such as another vehicle, a wall, or a bollard\u2014they are reflected and received again by the sensor.<\/p>\n\n\n\n<p class=\" translation-block\">The control unit of the <strong>PDC parking assistance system<\/strong> calculates the <strong>exact distance to the obstacle<\/strong> based on the time the signal needs to travel to the obstacle and back.<\/p>\n\n\n\n<p>The closer the vehicle gets to an object, the faster the warning signals are emitted.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">How is the driver warned?<\/h4>\n\n\n\n<p>As soon as an obstacle is detected, the system informs the driver in several ways:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\" translation-block\"><strong>acoustic signals (beeping sounds)<\/strong> that become faster the closer the obstacle is<\/li>\n\n\n\n<li><strong>visual display on a screen<\/strong><\/li>\n\n\n\n<li class=\" translation-block\">display in the <strong>vehicle display or infotainment system<\/strong><\/li>\n<\/ul>\n\n\n\n<p>In some systems, the distance is also displayed graphically, allowing the driver to immediately see on which side the obstacle is located.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Activation of the parking assistance system<\/h4>\n\n\n\n<p class=\" translation-block\">Most <strong>parking sensor systems<\/strong> are activated automatically as soon as the <strong>reverse gear is engaged<\/strong>. In vehicles with front sensors, the system is often also activated when driving forward slowly or by pressing a button.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Retrofitting a parking assistance system<\/h4>\n\n\n\n<p class=\" translation-block\">Many vehicles can easily be <strong>retrofitted with a parking assistance system<\/strong>. Modern <strong>parking sensor retrofit kits<\/strong> are suitable for numerous models and can be installed either as universal systems or as vehicle-specific solutions.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p class=\" translation-block\">If you are unsure which system is suitable for your vehicle, we will be happy to advise you.<br>Simply contact us via our contact form.<\/p>\n\n\n\n<p><a href=\"https:\/\/wibutec.de\/en\/kontakt\/\">Contact us \u2013 Wibutec<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Eine Einparkhilfe (PDC \u2013 Park Distance Control) arbeitet in der Regel mit Ultraschallsensoren, die in der Sto\u00dfstange des Fahrzeugs montiert werden.
