Car Parking Sensors

Steelmate Front and Rear Parking Sensors - Take the risk out of Parking and Reversing

Parking Sensors are proximity detectors for road vehicles which can alert the driver to unseen obstacles during parking. Parking Sensor systems use ultrasonic proximity sensors embedded in the front and/or rear bumpers, to measure the distances to nearby objects at low level. The Parking Sensors measure the time taken for each sound pulse to be reflected back to the receiver.

Depending on the speed of the vehicle and the distance to the obstacle, the system will warn the driver by audible and/or visual means about the risk of collision. The feedback to the driver will generally indicate the direction and proximity of the obstacle. Warnings are deactivated when the vehicle exceeds a certain speed, and can be switched off for situations such as stop-and-go traffic.

Audible Feedback
The most common form of feedback to the driver in a car with Parking Sensors is audible "beeps" and/or tones. Generally, the frequency of the beep indicates distance from an obstruction, with the beeps becoming faster the closer the vehicle moves to an object. A continuous tone may be heard when the vehicle is extremely close, often warning a driver to stop immediately to avoid collision.
Visual Feedback
Some Parking Sensor Systems use visual aids as well as or instead of audible tones, such as LED or LCD readouts to indicate distance from an object. The direction and distance to the obstacle is indicated by the location and strength of the warning symbols
