Blind Spot Monitoring: A Guide To Enabling This Feature

Blind-spot monitoring (BSM) is an advanced driver assistance system (ADAS) that helps drivers stay aware of their surroundings and avoid accidents. It uses sensors and sometimes cameras to detect vehicles or other objects in a driver's blind spot and alerts the driver with visual or auditory cues. BSM is available as a factory-installed feature in many modern vehicles, but it can also be installed as an aftermarket addition.

Blind-spot monitoring systems can be purchased as an aftermarket product and added to older vehicles

Blind-spot monitoring systems are a great way to enhance your driving experience and improve safety. While they were once only found in high-end luxury cars, blind-spot monitoring systems have now become more accessible and are available as an aftermarket product for older vehicles.

An aftermarket blind-spot monitoring system can be purchased for vehicles that lack certain types of technology, especially older models. These systems are designed to alert you of potential hazards in your blind spots, which are areas that you might not be able to see immediately when driving or changing lanes. This added safety feature can provide you with peace of mind and help prevent accidents.

The aftermarket blind-spot monitoring systems typically consist of sensors and indicators. The sensors act as the eyes of the system, using technologies like sonar, radar, lidar, or cameras to detect vehicles, objects, or pedestrians in adjacent lanes or blind spots. Once the sensors detect something, they trigger the indicators, which usually consist of visual LED lights and an alarm to notify you of the potential hazard.

When choosing an aftermarket blind-spot monitoring system, it's important to consider the type of indicators you prefer. Some systems offer visual signals, while others have audio alerts or a combination of both. You can also adjust the volume of the indicator to ensure it's at a comfortable level.

The installation process for aftermarket blind-spot monitoring systems can vary in complexity. While some systems offer easy-to-follow instructions for self-installation, others may require professional installation. It's recommended to consult your vehicle's manual or a professional for guidance on the specific installation process for your car.

Overall, adding a blind-spot monitoring system to your older vehicle can significantly improve your driving experience and safety. With this system in place, you can feel more confident on the road, knowing that you have an extra set of eyes keeping track of potential hazards.

The system uses sensors and sometimes cameras to detect objects in a driver's blind spot

Blind-spot monitoring is a safety feature that uses sensors and sometimes cameras to detect objects in a driver's blind spot. This technology is designed to assist drivers and help prevent accidents by alerting them to potential hazards that they might not be able to see.

The system typically employs ultrasonic, radar, or sonar sensors embedded in the side mirrors or rear bumper of a vehicle to detect objects in adjacent lanes. When an object is detected, the driver is alerted through visual and/or audible warnings. These alerts usually consist of lights and beeps, indicating that it is unsafe to change lanes.

Some vehicles also use cameras as part of the blind-spot monitoring system or to complement the sensors. These cameras are typically side-mounted and work in conjunction with the sensors to track approaching traffic in adjoining lanes.

While blind-spot monitoring is not a replacement for manually checking one's blind spots, it provides an extra layer of safety and convenience. It is especially useful for larger vehicles with bigger blind spots and reduced rear visibility.

Aftermarket blind-spot monitoring systems are available for older vehicles that lack this technology. These systems can be purchased from retailers like Amazon, Walmart, and Crutchfield, with prices ranging from $300 to $500 for a solid system. Professional installation is recommended to ensure proper functioning and can cost at least $200.

When the system detects an object, it alerts the driver through visual or auditory cues

Blind-spot monitoring (BSM) is a safety feature that can be a literal lifesaver for drivers. When the system detects an object, it alerts the driver through visual or auditory cues, or a combination of both. These alerts are designed to be attention-grabbing but not startling, and in some systems, you can adjust the volume of the auditory alerts. Visual alerts are usually in the form of a yellow warning light, and they can appear on the outboard rearview mirror, the A-pillar (the pillar between the windshield and the front door), the driver information display, or the head-up display. Some systems also provide auditory alerts, which may sound when you use your turn signal to indicate a merge into an occupied lane.

Visual alerts are standard on most BSM systems, and they are designed to be easily visible without the driver having to take their eyes off the road. The lights are typically bright and positioned in the driver's peripheral vision, making it easy to notice when the system detects an object in the blind spot. Some systems also include a heads-up display that shows a live feed from side-mounted cameras, providing an even clearer picture of the vehicle's surroundings.

Auditory alerts are another effective way to warn the driver of potential hazards. These alerts are typically loud and clear, ensuring that the driver notices them. In some systems, the volume of the auditory alerts can be adjusted to suit the driver's preferences and the ambient noise level in the cabin. This customisation ensures that the alerts are noticeable but not overly startling or distracting.

In addition to visual and auditory alerts, some advanced BSM systems provide tactile feedback through the steering wheel. This feature, known as haptic feedback, adds another layer of warning by vibrating the steering wheel when the system detects an object in the blind spot. This feature is particularly useful in noisy environments or for drivers who may have difficulty hearing the auditory alerts.

It's important to note that while BSM systems provide valuable assistance, they should not be solely relied upon. Drivers should still use their mirrors, check their blind spots, and be aware of their surroundings at all times.

Blind-spot monitoring systems are available at different price points and vary in accuracy

Blind-spot monitoring systems are available at different price points, ranging from $100 to $750, and vary in accuracy. The accuracy of the system depends on the type of radar used, with 77GHz and 79GHz radars offering greater accuracy than 24GHz options. The higher the frequency band of the radar, the better the detection and the faster the warning to the driver.

The most affordable blind-spot monitoring systems, costing $250 or less, tend to have limited functionality and accuracy. They include a few sensors and a basic level of indicator technology. Systems in the $250 to $500 price range offer increased accuracy, but are still not as accurate as factory-installed systems in newer vehicles. The highest accuracy is found in the premium systems costing $500 or more, which use advanced algorithms to reduce the likelihood of false triggers.

The cost of a blind-spot monitoring system also depends on its features. Systems with a buzzer alarm system, extra mirrors, or a built-in camera will be more expensive. The type of vehicle also affects the cost, with truck systems generally being the most expensive, followed by car systems, and motorcycle systems being the least costly.

Aftermarket blind-spot monitoring systems are available for older vehicles that lack this technology. While these systems are slightly less accurate than factory-installed ones, they can still be effective in increasing driving awareness, response time, and overall safety.

The system can be bundled with rear cross-traffic alert features

Blind-spot monitoring (BSM) is often bundled with rear cross-traffic alert (RCTA) features. RCTA is a useful tool when reversing out of parking spots, as it detects vehicles, objects, or pedestrians in the car's path. When shifting into reverse, RCTA is activated and monitors vehicles on a course to cross behind the car. When the system detects a crossing vehicle, it issues an audible warning. More advanced RCTA systems also recognise pedestrians and will sound an alert when a person is behind the vehicle.

Some car manufacturers, such as Nissan and Ford, bundle BSM with their active safety technologies. Others, like Toyota, Hyundai, Honda, and Subaru, offer BSM in upper trims or more expensive vehicles.

The Ford Blind Spot Information System (BLIS) with Cross-Traffic Alert is an example of a bundled BSM and RCTA system. BLIS uses radar sensors on both sides near the rear of the vehicle to detect objects in the blind spot zone. When an object is detected, the driver is alerted with an indicator light in the side-view mirror. The Cross-Traffic Alert feature uses the same radar technology to detect traffic when the vehicle is in reverse. When a vehicle is approaching from either side, an indicator light flashes in the side-view mirrors, an audible warning is emitted, and a visual display in the message centre indicates the direction of the approaching vehicle.
