A sensor specifically designed for use in low-speed maneuvering scenarios (Speed 10 km/h) is the Ultrasonic Parking Sensor for Parking. It gauges how long an object takes to fly (Echo-Localization principle).
Parking sensors are close-range sensors installed in motor vehicles to warn the driver of potential hazards when parking. These systems employ either ultrasonic or electromagnetic sensors.
These systems use sensors that are visibly reduced within nearby grills or recesses or installed in the front and/or rear bumper fascias to measure the distances to nearby objects.
A control unit measures the return interval of each reflected signal and determines object distances after the sensors generate acoustic pulses.
The device periodically alerts the driver via acoustic tones, the frequency of which indicates object distance, with quicker tones denoting closer closeness and a continuous tone denoting a minimum pre-defined distance.
Systems may also come with visual aids like readouts on an LCD or LED that indicate how far away an object is. On the infotainment screen of a car, there may be a vehicle pictogram that shows surrounding objects as colored blocks.
When the reverse gear is selected, rear sensors may be engaged; they may also be deactivated when any other gear is selected. To prevent more annoyance warnings, front sensors may be manually activated and deactivated automatically when the vehicle reaches a predetermined speed.
A flat object or an object too small to reflect sounds, such as a narrow pole or a longitudinal object aimed directly toward the vehicle or close to an object, may escape detection by an ultrasonic system because it depends on the reflection of sound waves.
Returned sound waves from flat objects having angles other than vertical may be refracted away from the sensors, making them harder to detect. Wool and moss are examples of soft objects with strong sound absorption but weaker detection.
The Global Ultrasonic Parking Sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Jieshun recently introduced a completely new ultrasonic parking sensor together with an all-encompassing ultrasonic parking guiding system.
The system can gather real-time data on the parking spaces using the parking sensors placed above the spaces. The parking sensor will automatically recognize a parked automobile and turn the signal from green to red.
The primary controller will then compile all the data, process it, and send information about available parking spaces to the front-end display screen, directing more vehicles into the open spots.
Ultrasonic parking advice is still crucial even if many parking lots are gradually adopting video parking guidance systems. Ultrasonic parking guiding systems are simpler to implement in terms of installation. Ultrasonic parking systems are substantially less expensive and require no video storage compared to video parking systems.
