What is Blind Spot monitoring system?

This driver assistance technology senses cars coming up in your blind spot behind or alongside you, and if your turn signal is on, it alerts you not to change lanes.

One of the newest technologies used in automotive safety is the Blind Spot Monitoring System.
The blind spot Monitoring system allows the driver to monitor the position of blind spots on the sides of the car. The system entered the automotive industry for the first time in 1995, and as with many other technologies, its origins are military and war jets. The system is based on motion sensors, as well as many technologies used in the field of automotive safety; hence the system is also known as blind spot sensor. Blind spot detection is a key technology among driver aids that provide 360 degrees of electronic coverage around your car, whether you are at speed or moving slowly. This circle of safety also includes adaptive cruise control, lane departure warning, rear and front parking sonar, the rear traffic alert, and parking cameras (ranging from rear-only through four cameras providing a birds-eye view of the car as you snake into and out of tight spaces). This driver assistance technology senses cars coming up in your blind spot behind or alongside you, and if your turn signal is on, it alerts you not to change lanes. You’re warned by a flashing light on the side view mirror and then a beep or steering wheel vibration. If you’re not planning to change lanes (there is no turn signal on), the warning light glows steadily but doesn’t flash and there’s no audible alert. Unfortunately, many road accidents are due to the car’s outright drive to the left or right and to other objects. The left and right blind spots of the car extend along the horizons both perpendicularly and horizontally, and this causes the driver to have very little visibility from the sides of the vehicle. Even side mirrors can only display a limited-angle, and do not see points near the car’s body reflected in the image. The Blind Spot monitoring system has solved this problem. The system, which is today featured in modern and luxury vehicles such as the new DS products, is able to inform the driver by using a motion sensor.

How Do Blind Spot Monitors Work?

The blind spot monitoring system in today’s cars is an advanced technology, and usually each company uses different mechanisms to build and design its system for its products. In modern DS cars, a mobile-propulsion sensor is used. In this system, sensors are installed underneath the car’s side mirrors, and when activated by the driver, they begin to release wavelengths of short wavelength. Because of their short wavelengths, these waves can provide a more precise view of the blind spots of the car to the driver. The propagation of these waves is carried out continuously and without stopping; therefore, when a body is placed against these waves and their path is cut off, the sensor sends a message to the ECU. This message is sent to the driver as a warning. This warning may be displayed on the front of the driver’s monitor or the light mounted on the side of the mirror.
