Brief History of Blind Spot Monitor System

George Platzer came up with the concept of blind spot monitors. However, the device wasn’t invented till 2001. Platzer introduced the idea that efficiently adjusting the side-view mirrors can lower the dangers of a car’s blind spots. While this tip can work somewhat, finding the right positioning can be pretty challenging.

Another drawback of this idea was that many drivers were inexperienced with adjusting their side-view mirrors. The new positions put them in even graver danger. That is when Platzer presented the concept of blind spot monitors to Ford. George Platzer claimed this device is “an elegant and relatively inexpensive solution” to avoid the dangers of a vehicle’s no-zones.

First Implementation

The first implementation of the blind spot detection system project was also by Volvo in 2001. It introduced the SCC concept car with a BLIS (blind spot information system). However, the device was then removed from production in 2001. Instead, it was implemented in the Volvo XC90 SUV in 2003. The BLIS system used a camera to detect vehicles in the car’s blind spots and had an alert system to notify the driver.

While modern blind spot monitor systems have the same basic framework, they are more advanced. Today, they use radar-based sensors that are weather-resistant, unlike cameras.

4 Popular Car Companies to Adopt the Blind Spot Monitor System

Today, most modern car companies integrate a blind spot monitor in their models. But the following manufacturers are considered the pioneers in adopting this driving assistance technology. Let’s look at them in detail:


1. Volvo

Volvo was the first car company to adopt the blind monitor system’s concept. They implemented BLIS in their 2003 release. The company is often regarded as the pioneer of understanding blind spot dangers. It was given the award for AutoCar Safety and Technology award for using the first BLIS.

2. Ford

Ford is another popular car company to adopt blind spot monitors. Platzer presented his idea of this system to the Ford Motor Company. Since then, the company has utilized blind spot detection systems in many cars, starting in 2009 with Ford Fusion and Hybrid.

3. Mazda

Mazda is the Japanese pioneer in introducing a car with a blind spot monitor system. The company released its 2008 Mazda CX-9 with this driving assistance technology. Later on, it became a recurring feature in its cars from 2009 to 2013. However, Mazda calls this device BSM (blind spot monitoring) instead of BLIS.

4. Mitsubishi

Mitsubishi is one of the later companies to adopt blind spot monitoring systems. This technology was seen in their Pajero Sport, released in 2016. However, the company has since maintained this feature throughout its new releases.

Components Of Blind Spot Monitor System

A blind spot monitor system consists of some components working together to ensure the driver’s protection on the road. Generally, the essential equipment comes in the system package. But that can vary depending on the manufacturer. OYI Electronic provides all the accessories and remote support you will need to install and use blind spot monitors.

That said, let’s go through its components!


1. Radar-based Sensors

The radar-based sensors play the most crucial role in blind spot monitors. These devices emit millimeter waves to detect objects in the vehicle’s surroundings. Typically, their waves can cover up to 10 feet behind the car’s bumper. The sensors will detect any vehicle entering this area.

The best part is that these sensors are weather-resistant and water-proof. They provide accurate results by measuring the oncoming car’s speed and distance, even in extreme weather conditions.

2. LED Lights

LED lights are the interface between the driver and the system. When the sensors detect a vehicle, the waves immediately trigger the LED lights. They start flashing, meaning there is a vehicle in the blind spots.

Generally, modern systems have LED lights connected to buzzers. Not only do they flash, but they create an audible warning. This feature can be good to alert the driver even if they are distracted.

3. Cables

A wireless blind spot detection system is more convenient, as it removes wire clutter. Also, it keeps the interior organized and clean. However, most systems use cables, requiring you to connect with a power source.

You can keep your interior clean even if you choose a system with wires. The key is to hide the cables under the car seats. Make sure to run the wires as efficiently as possible.

4. Additional Equipment

If you choose a modern blind spot monitor system, you’ll get some additional accessories. For instance, newer systems have GPS navigation, RCTA, and automated braking. All of these functions use different equipment than the standard blind spot detection. But the product’s manual will provide insight into these additional features’ installation and operation methods.

Proven Effects Of Blind Spot Monitor System

A blind spot monitor system is beneficial for personal and professional drivers alike. This driving assistance system can reduce road accidents. It has a proven track record, as it has lowered lane-change crashes by 14%.


According to a study, more than 50,000 road crashes can be prevented if everyone in the US uses blind spot detection systems in cars. This driving assistance tool can also reduce road accidents’ impact by minimizing injuries.

That is why many governments, including Italy, emphasize equipping blind spot monitors in vehicles, especially trucks. This straightforward system can prevent road accidents commonly occurring during lane changing and turning. At the same time, a blind spot monitor offers accurate results, regardless of the weather condition.
