Monitor Bezel Blind Spots: Understanding The Unseen

Blind spots are areas on either side of a car that the driver cannot see when looking into the rearview or side-view mirrors. To compensate for this, many car companies offer vehicles with blind-spot monitoring (BSM), a system that uses technology such as radar, ultrasonic sensors, and cameras to detect vehicles or objects in a driver's blind spot and alert the driver. BSM is designed to increase safety by providing visual, auditory, or tactile warnings to the driver, although it is not a substitute for checking mirrors and looking over one's shoulder. While BSM was once only found in high-end luxury cars, it is now available in various vehicles, including economy cars and pickup trucks, and can also be added to older vehicles through aftermarket kits.

How does a monitor bezel blind spot work?

A monitor bezel blind spot refers to the area on either side of a car that the driver cannot see when looking into the rearview or side-view mirrors. Blind spots are dangerous because they can hide vehicles approaching in adjacent lanes, often resulting in crashes when merging.

Blind-Spot Monitoring (BSM) is an advanced driving assistance system (ADAS) designed to increase safety by alerting the driver to vehicles that may be in their blind spot. BSM uses radar, ultrasonic sensors, or cameras to detect vehicles in the driver's blind spot and then warns the driver through visual, auditory, or tactile cues.

The simplest BSM systems use radar or ultrasonic sensors embedded in the rear bumper to detect vehicles approaching from the side. More sophisticated systems employ side-mounted cameras in addition to sensors. Once the system detects an approaching vehicle, it warns the driver through a visual indicator (such as a blinking light on the side mirror or in the gauge cluster), an auditory signal (such as a beeping noise), or a tactile alert (such as a vibrating steering wheel or seat).

Some BSM systems also provide more intrusive interventions, such as applying subtle autonomous steering or braking input to prevent the driver from changing lanes into another vehicle. These systems can even steer the driver back to the centre of their lane. While BSM is a valuable safety feature, it is important to note that it is not a substitute for proper mirror usage and checking over one's shoulder before merging or changing lanes.

What are the benefits of a blind spot monitor?

All vehicles have blind spots, which are areas on either side of a car that the driver cannot see when looking into the rearview or side-view mirrors. Blind spots are why a driver should always turn their head and check for cars before changing lanes. To help drivers become more aware of objects in these blind spots, many car companies offer vehicles with blind-spot monitoring (BSM).

• It will prevent some accidents and can minimize others: Blind-spot monitoring can help prevent accidents by alerting the driver to vehicles that may have escaped visibility in the side-view mirrors. It also helps to minimize accidents by providing an early warning, increasing the time the driver has to respond.
• Increased driving awareness: A blind-spot monitor provides extra coverage by constantly viewing the spots that drivers can't always track while driving.
• Increased confidence: Drivers will feel safer and more confident, and so will their passengers.
• Stress relief: Driving in close quarters can be stressful, and a blind-spot monitor can relieve some of that stress by monitoring areas that are hard to see.
• The larger the vehicle, the greater the benefit: The larger the vehicle, the bigger the blind spot. The bigger the blind spot, the more a blind-spot monitor can help prevent the driver from changing lanes into another vehicle.

How do you install a blind spot monitor?

Blind-spot monitoring (BSM) is a safety feature that helps drivers become more aware of objects in their blind spots. It is an advanced driving assistance system (ADAS) designed to alert the driver to vehicles that may not be visible in the side-view or rearview mirrors.

If your vehicle does not have BSM, you can install an aftermarket blind spot monitor. Here is a step-by-step guide on how to do it:

Step 1: Prepare the Calibration

Place a measuring tape parallel to your vehicle's wheels. Take out the calibration cloth from your system and place it behind the vehicle, aligning it with the measuring tape at a 90-degree angle. Use a level to ensure it is straight, and mark a line on the rear bumper.

Step 2: Remove and Clean

Remove the rear bumper and, if necessary, the taillights. Clean the calibrating positions on the inner rear bumper with a cloth and rubbing alcohol.

Step 3: Position the Magnets

Place one magnet on the outside of the vehicle, along the line you marked, and the other inside, so they attract each other. Play around with the placement to find the optimal angle for the sensors, which should be around 20 degrees from the bumper. Mark the spot inside the bumper where the magnet rests.

Step 4: Install the Sensors

Apply adhesive to the sensors and stick them to the marked spots inside the bumper.

Step 5: Mount the Indicators

Mount the LED indicators inside the cabin, ensuring they are in a location that is easily visible without taking your eyes off the road. Some kits may have specific recommendations for indicator placement.

Step 6: Adjust the Volume

Test the system and adjust the volume to ensure it is loud enough to hear without being too startling.

Step 7: Seek Professional Help if Needed

If you encounter any issues or have questions during the installation process, reach out to a service centre for professional assistance. Some blind spot monitor systems can be complex, and a professional installation may be recommended.

By following these steps, you can enhance your driving experience and increase your awareness of potential hazards on the road.

What are the limitations of a blind spot monitor?

Blind-Spot Monitoring (BSM) is a driver aid system designed to increase safety by alerting the driver to vehicles that may be in their blind spots. While BSM is a valuable safety feature, it does have some limitations.

Firstly, BSM systems are primarily designed for highway use and highway speeds, and their effectiveness may be reduced on city streets or slower roads. Additionally, BSM has a maximum speed differential limit, meaning it cannot detect vehicles passing at significantly higher speeds. This limit varies by system, and drivers should refer to their owner's manual or contact the manufacturer for specific information.

Another limitation of BSM is that it relies on sensors and cameras to detect vehicles. If these sensors become blocked by snow, ice, mud, dirt, or condensation, the system may not function correctly. It is important for drivers to regularly clean and maintain the sensors and cameras to ensure proper operation.

Furthermore, while BSM can detect most vehicles, it may not always detect smaller objects such as motorcycles. It is also important to note that BSM is not a replacement for safe driving practices. Drivers should still use their turn signals, check their mirrors, and look over their shoulders when changing lanes, as BSM is only an assistive technology.

Finally, BSM systems are designed to monitor the sides and rear of the vehicle, but they do not always detect objects directly behind the vehicle or approaching from the opposite direction. Additionally, not all BSM systems recognize pedestrians, cyclists, or pets, so drivers should remain vigilant and use their own judgement when operating their vehicles.

How much does a blind spot monitor cost?

Blind-spot monitoring (BSM) is an advanced driver-assistance system (ADAS) designed to increase safety by alerting the driver to vehicles that may be in a blind spot. All vehicles have blind spots, which are areas on either side of a car that the driver cannot see when looking into the rearview or side-view mirrors.

The cost of a blind-spot monitoring system varies depending on its features and specifications. Basic systems can range from $100 to $350, while more advanced systems with features like a buzzer alarm or extra mirrors can cost between $350 to $750. The price also depends on the type of vehicle, with truck blind-spot systems generally being the most expensive, followed by car systems, and motorcycle systems being the least costly.

Aftermarket blind-spot monitoring kits are available for older cars, ranging in price from $300 to $500, with installation costing at least an additional $200. These kits typically include sensors and indicators, such as warning lights and audio alarms.

Blind-spot monitoring systems are a valuable investment, offering increased safety and peace of mind for drivers and passengers alike. They can prevent accidents, improve driving awareness, and provide early warnings to increase response time.
