What do you do if you are behind the speeding car slow and just barely got a gap to overtake? Which appeared in your mind of a skepticism that eventually could even cause an incident. Addressing this problem, BMW had its own answer. The German manufacturer has just released a high-tech gadget called BMW Narrow-passage Assistant. Literally this gadget serves as a navigational aide or assistant driver when trying to overtake at a tight angle.
The technology behind the BMW Narrow-passage Assistant is actually quite simple. This tool embedded in a computer system uses various sensors to determine whether the car can go between the narrow roads without scratching the paint or crashing a car. How it works, BMW Narrow-passage Assistant take into account, when calculating the lateral distance, the yellow road signs, safety fences, barriers and even a vehicle in the neighboring lane. This system is activated simultaneously with a lane departure warning system, which helps the orientation of the yellow road signs.
It calculate the area of the road, referred to by BMW
is preSite and clearance lateral side of the object, the distance is called the BMW, Insite. The calculation is being carried out after information received from either laser or ultrasonic sensors. Depending on the findings of the sensor, assistant sends the result to the driver with visual displays and advise them what to do.
Second, understand preSite. PreSite comes from a system that is intended to display the effective width of the available road, before the maneuver precedes. PreSite showing the lateral clearance on both the left and right side, sending three types of readings back to the driver. One ring means a lot of space (0.5-1 meters), 2 circle means a small space (0.2 - 0.5 meters), while the third circle means it will be narrow (below 0.2 meters). If the distance to the bottom of the security clearance, the system will send an additional warning through HUD.
The third is that Insite, after assessing the driver he had just enough room to squeeze through, Insite monitoring system kicks in This makes the driver in maneuvering along the track, the lateral distance monitoring. Using data derived from the laser, the system will send back information directly through the steering wheel, as well as through HUD.
Fourth, Sensor. There are two types of sensors used by BMW Narrow-passage Assistant, which as said, laser and ultrasonic-based. Lasers are used by the system to monitor the space in front of the vehicle, scanning for other cars, obstacles and safety fence. Laser works at a beam angle of 160 degrees horizontal and one vertical of 3.2 degrees. They can scan the road ahead for distances up to 100 meters. Ultrasonic sensors, on the other hand, measures the lateral clearance to objects. They work at an angle of 32 degrees horizontally and vertically of 9.5 degrees. They have a range of up to 5 meters, depending on the speed of the car. BMW's own testing this new gadget is the variant of the BMW X5 and change the degree of this car so a compact SUV. Although still a lot of opposition because of the reliance on the tool. The usefulness of this system is obvious, because it can help reduce the stress on both the driver who does not know where the car should be as well as possible damage to arise as a result of vehicle collisions.
