Auto parking sensor system

Types of auto parking sensor system

Auto parking sensor systems are devices installed in vehicles that assist drivers while parking. Parking sensors use ultrasonic sound waves to detect obstacles in a vehicle's path. The sensors are usually mounted on the vehicle's bumper. When the vehicle reverses, the sensors can detect nearby objects. There are two types of parking sensors:

• Park distance control: Park distance control is an automatic parking sensor system that helps drivers park their cars accurately. The system uses ultrasonic sensors located on the rear and front bumpers to detect nearby objects. When a driver attempts to park their car, the sensors emit sound waves that help identify obstacles. The system also has a control unit that processes data from the sensors and displays it on the screen. Park distance control can help avoid damage to pedestrians and objects close to the car.
• Cross traffic alert: Cross-traffic alert is a parking sensor system found in modern vehicles. The parking sensor system alerts drivers of oncoming traffic when backing out of a parking space. The system uses radar sensors mounted on the rear bumper to monitor the traffic in parking lots. When a driver reverses their car from the parking space, the cross-traffic alert system can detect vehicles or pedestrians close to the car and give visual and audible warnings. The system helps prevent collisions with objects or pedestrians that may be out of sight.

Specification and maintenance of auto parking sensor systems

Auto parking sensor systems have several specifications that vary depending on the manufacturer and model. These specifications include:

• Sensor type: The sensor type determines the capability of the parking sensor system. Different sensor types have various functionalities. The ultra-sonic sensors are designed to emit high-frequency sound waves. These sound waves bounce off surrounding objects, creating an echo that the sensor interprets, indicating the distance and proximity of obstacles. On the other hand, electromagnetic sensors work by creating a magnetic field around the vehicle, detecting changes in the field caused by nearby objects or obstacles. This system is generally less common than the ultrasonic sensor system.
• Number of sensors: The number of sensors in a parking sensor system can vary. Some vehicles are manufactured with only two sensors integrated into the rear bumper. This is mainly for basic parking assistance. Others come with four sensors placed on the front and rear bumpers. The four-sensor system offers more comprehensive parking assistance, making it easier to detect obstacles when parking.
• Detection range: The detection range is important because it determines the distance the sensors can detect obstacles. Different parking sensor systems have varying detection ranges, typically between 1 to 2 meters. This allows the sensors to provide accurate distance information and warning alerts to the driver. Some advanced models of the parking sensor system have a longer detection range of up to 3 meters. This extended range allows for earlier detection of obstacles, enhancing overall safety during parking.
• Alert system: Different auto parking sensor systems have different alert systems. The alert system is designed to notify the driver about nearby obstacles and their proximity. Some basic models have only audio alerts, which become increasingly frequent as the vehicle approaches an obstacle. More advanced models feature both visual and audio alerts. The visual alert is displayed on a screen, showing the distance to the obstacle, while the audio alert gives a warning.
• Integration with vehicle systems: Parking sensor systems are designed to integrate with other vehicle systems. This includes the central control unit and the display unit. This integration enables advanced features, such as automatic brake activation in case of a collision and integration with rear-view cameras. The integration enhances parking sensor functionality, improving overall safety and convenience while parking.
• Power supply: Parking sensor systems have different power supply specifications. They can be powered through the vehicle's electrical system or have their own dedicated power source. The parking sensor systems that have a dedicated power source offer more reliable performance, especially in advanced models with features like adaptive cruise control.

Different parking sensor systems have different maintenance requirements, which are as follows:

• Regularly inspect the sensors for dirt, debris, and damage. This ensures the sensors maintain their optimal performance. The sensors are usually located on the bumpers and can accumulate dirt and debris from regular driving. Clean the sensors to remove any build-up using a soft cloth and mild soap. Avoid using abrasive materials that may scratch the sensor's surface.
• Visually check the wiring and connections of the parking sensor system. This helps to identify any loose connections or damaged wires. Properly secure any loose connections and replace any damaged wires to prevent malfunctioning of the parking sensor system.
• Some parking sensor systems may require software updates from the manufacturer. This is to ensure the system operates effectively. Contact the manufacturer's technician to schedule the updates. The technician will use specialized tools to install the latest software updates to the parking sensor system, improving functionality and performance.
• When replacing the vehicle battery, ensure the parking sensor system is properly reconnected. Follow the manufacturer's instructions for disconnecting and reconnecting the parking sensor system to prevent any damage or malfunctioning.
• Some advanced parking sensor systems have features like automatic emergency braking. In such cases, ensure the brake system is properly maintained and functioning. This includes regularly inspecting the brake pads, brake discs, and brake fluid levels and replacing them when necessary. This enhances the parking sensor system's safety features.

How to choose an auto parking sensor system

When choosing an automatic parking sensor system for resale, consider the following factors:

• Market trends: Consider the current market trends and what customers are looking for. Are they looking for sensors that come with a display? Do they want sensors that can connect to their smartphones? Knowing the trends will help select products that will sell out quickly.
• Quality: Choose parking sensors from reputable manufacturers known for their quality. The sensors should last a long time and offer accurate readings. If the sensors keep on giving false readings, it will not only cause accidents but will also ruin the reputation of the business.
• Price: The sensors should be affordable, but they should also offer value for money. Avoid overly cheap sensors, as they might be of poor quality. Strike a balance between quality and affordability.
• Features: Choose sensors that are packed with features. The sensors should have a good detection range and an angle of the sensor to detect objects early. They should also have visual and audio alerts so that the driver can know what is happening behind the car. Sensors with a display screen that show the distance of the object from the car are also better.
• Ease of installation: Consider how easy the sensors will be to install. Can the average person install them by reading the manual, or do they need a professional? While installers make sure the sensors are working right, they can be costly. Choosing sensors that are easy to install will save the customer a lot of money.
• Compatibility: Ensure the sensors are compatible with various car models. Not every sensor is made to work with all car models. The sensors should be designed to work with different cars without any issues.
• Test and review: Look for customer reviews about the sensors. Find out if they are as good as the manufacturer claims. Also, test the sensors if possible before purchasing them.
