ACOUSTIC PARKING SENSORS
Parking sensors are proximity sensors for road vehicles designed to alert the driver to obstacles while parking. These systems, which use either electromagnetic or ultrasonic sensors, are marketed variously by vehicle manufacturers under proprietary brand names such as Park Distance Control, Park Assist, or Parktronic.ULTRASONIC PARKING SYSTEMS
- These systems feature ultrasonic proximity detectors to measure the distances to nearby objects via sensors located in the front and/or rear bumper fascias or visually minimized within adjacent grills or recesses.
- The sensors emit acoustic pulses, with a control unit measuring the return interval of each reflected signal and calculating object distances.
- The system in turn warns the driver with acoustic tones, the frequency indicating object distance, with faster tones indicating closer proximity and a continuous tone indicating a minimal pre-defined distance.
- Systems may also include visual aids, such as LED or LCD readouts to indicate object distance.
- A vehicle may include a vehicle pictogram on the car's infotainment screen, with a representation of the nearby objects as colored blocks.
ULTRASONIC PARKING SYSTEMS: WORKING
- Rear sensors may be activated when reverse gear is selected and deactivated as soon as any other gear is selected.
- Front sensors may be activated manually and deactivated automatically when the vehicle reaches a pre-determined speed — to avoid subsequent nuisance warnings.
- As an ultrasonic system relies on the reflection of sound waves, the system may not detect flat objects or object insufficiently large to reflect sound — e.g., a narrow pole or a longitudinal object pointed directly at the vehicle or near an object.
- Objects with flat surfaces angled from the vertical may deflect return sound waves away from the sensors, hindering detection
ADVANTAGES of ULTRASONIC PARKING SENSORS
- The cheapest form of parking aid.
- Sensors detect objects even when the car is stationary.
DISADVANTAGES OF ULTRASONIC PARKING SENSORS
- The ultrasonic backup sensors have difficulty detecting inclined surfaces or slightly reflective obstacles as shrubs and wire mesh.
- They also only detect objects directly behind or in front of the car, and may not work if the sensors are dirty or out of alignment.
- Fitting usually requires drilling the bumper, but stick-on sensors are available (though unattractive).
- Ultrasonic parking sensors are not suitable for use with a tow bar.
ELECTROMAGNETIC PARKING SYSTEMS
- Electromagnetic sensors rely on the vehicle moving slowly and smoothly towards the object to be avoided.
- Once detected, the obstacle, if the vehicle momentarily stops on its approach, the sensor continues to give the signal of the presence of the obstacle.
- If the vehicle then resumes its maneuver the alarm signal becomes more and more impressive as the obstacle approaches.
- Electromagnetic parking sensors are often sold as not requiring any holes to be drilled offering a unique design that discreetly mounts on the inner side of the bumper preserving the 'new factory look' of your vehicle
ELECTROMAGNETIC PARKING SYSTEMS: WORKING
- A system provides an alarm indicative of a presence of an obstacle in a vicinity of a vehicle.
- The system operates by electromagnetic detection and generates an oscillating radiofrequency signal.
- A transmitter transmits the generated oscillated radiofrequency signal to create, all around the transmitter, an electromagnetic radiofrequency near field.
- A receiver receives the electromagnetic radiofrequency near field.
- A detector is connected to the receiver and detects a perturbation resulting in a reduction of an oscillation amplitude of the electromagnetic radiofrequency near field, and an indicator indicates the detected perturbation of the received electromagnetic radiofrequency near field.
- Based on this operation, an obstacle in the vicinity of the vehicle can be detected.
ADVANTAGES OF ELECTROMAGNETIC PARKING SENSORS
- Suitable for use with tow bars, cycle racks, etc.
- Capability to approach the obstacle up to a few centimeters.
- Electromagnetic sensors are mounted inside the bumper, so there's no need for drilling.
DISADVANTAGES OF ELECTROMAGNETIC PARKING SENSORS
- Electronic parking sensors are more expensive –The factory-fitted cost is about the same as ultrasonic sensors.
- Electromagnetic sensors only detect objects once the car has started moving."
Acoustic Parking System PPT Report Conclusion: Indian Context
In a country like India where the parking space is always less than desired, sometimes due to heavy traffic and sometimes due to the irrational parking of others, such a parking assist system can be of great help. The only thing that repels the consumer from buying these systems is the heavy cost they have to pay for them. A vehicle with these systems can cost the buyer anywhere between 30k to 50k more in comparison to the ones which don’t have them. Indians, who are more comfortable with their “simple” cars than in paying the hefty price, often try to avoid the installation of these systems. If the cost is reduced and the people are convinced by the car manufacturers of the benefits of these systems, they may consider buying them for the sake of their vehicle’s safety.
