Many new vehicles come with advanced safety and collision avoidance systems. These systems include both active and passive solutions to help you maneuver your vehicle safely when on the road and when parking. One popular active safety solution is parking sensors. Parking sensors are like having eyes in the back of your head. Just like your eyes, they can judge distance. Prestige Car Audio and Marine in Metairie, Louisiana, can add parking sensors to almost any vehicle.
Passive versus Active
A passive safety system requires you to pay attention to it for it to help make you safer. The best example is a backup camera. Unless you look at the image on the screen, the system does not help. Active safety systems include parking sensors, as well as Lane Keep Assist, Lane Departure Warning and Forward Collision Warning systems. When these systems detect that you are in peril, they sound an audible alert.
How Parking Sensors Work
Parking sensor systems include at least four compact ultrasonic transceivers. We install these transceivers the front and rear bumpers of your vehicle at equal intervals from left to right. The control module included with the system sends a high-frequency signal to each transceiver, which in turn emits that signal as a high-frequency radio wave. When an object approaches, or – more accurately – when you approach an object, the signal is reflected back to the transceiver. The control module sounds an alarm, and you know to stop moving.
How Parking Sensors Detect Distance
The control module of the parking sensor kit can calculate the amount of time it takes for the transmitted ultrasonic signal to return to the transceiver. The faster the signal returns, the closer you are to an object. All of the parking sensor systems we install offer audible warnings that let you know as you get closer and closer to an object, such as a parked car or a wall.
Using a Parking Sensor System
Most of the parking sensor systems we install include four sensors for the rear bumper. The system activates when you put the transmission into reverse. As you move backward and approach an object, the system controller will start to emit a beeping sound when you are between 5 and 3 feet from the object. When you are between 3 and 2 feet from the object, the speed of the beeping increases. Within a distance of 1 to 2 feet, the beeping increased in speed once again. Finally, when you are less than 1 foot from the object, the beeping stops and the system produces a solid tone. These distance ranges can vary slightly depending on the vehicle bumper height, but they are typical of our systems.
