Blind spot monitor
The blind spot monitor or blind-spot monitoring is a vehicle-based sensor device that detects other vehicles located to the driver’s side and rear. Warnings can be visual, audible, vibrating, or tactile.Get more news about blind spot sensor,you can vist our website!
Blind spot monitors may do more than monitor the sides and rear of the vehicle. They may also include "Rear Cross-Traffic Alert", "which alerts drivers backing out of a parking space when traffic is approaching from the sides.
Drivers are taught to assess surrounding traffic before changing lanes by checking their rearview and side mirrors and looking over each shoulder. However, even for those who follow this sequence of checks, the vehicle's blind spot – the area alongside and just behind the vehicle – is a constant source of danger and often the cause of serious accidents. To make changing lanes safer, the blind spot detection warns of impending collisions.The basic variant of blind spot detection can be implemented using ultrasonic sensors or corner radar sensors. The function uses the sensors to cover the dangerous blind spot. If another vehicle is situated in the monitored area, the driver is alerted to the potential danger by means of a warning sign in the side mirror. If the driver fails to spot or ignores this warning and activates the turn signal to change lanes, the system can also trigger an additional warning. The system recognizes stationary objects on or alongside the road, such as guardrails, masts or parked vehicles, as well as the driver's own overtaking maneuvers – and does not trigger the warning in this case.
The advanced variant of blind spot detection works by using two corner radar sensors that are concealed in the rear bumper – one on the left, one on the right. These two sensors monitor the area alongside and behind the car. Powerful control software collates the sensor information to create a complete picture of all traffic in the area behind the vehicle. The rear corner radar sensors exceed the sensing range of the ultrasonic sensors. In contrast to the ultrasonic-based system, even fast-approaching vehicles can thus be detected at an early stage before a lane change.
