The Driver Assistance system (DA) was presented by Volkswagen company for the first time in 2011 named “Temporary Auto Pilot” (shortened TAP), and it has become a standard or available functionality in the lineup of 2016 with the changed name now.
DA is further broken into several pieces of functionality. Let’s consider them below.
1. Adaptive Cruise Control.
It maintains the distance between your car and the front car (the adjustable value), and it keeps the vehicle on the set speed. On Jetta lineup and manual-gear Golf, this option automatically turns off below the 19 mph speed. The system’s override is done in several ways: speeding up, braking, turning the wheel. The set speed is maintained with the clear road in front of a car, and it slows itself down when approaching the object on your lane in front of you.
2. Front Assist system.
It helps the driver to avoid collisions with the still and moving objects – a car or anything else that is located on your lane in the front. The driver is alarmed visually and with a sound about an obstacle. If the driver doesn’t do anything to stop the car – the system brakes down automatically to slow down or fully stop the car. If a driver brakes too lightly to avoid the collision, the system accelerates the breaking process to make sure the car avoids the impact. If the minimal distance between the front car and your car has been sent, when reaching it on the move, the car will slow down and maintain the speed until the front car drives faster allowing increasing the speed maintaining the safe distance.
3.Blind Spot Monitor.
The radar sensors scan the rear side of the vehicle and alert the driver when and if any object appears on the adjacent lane from the back of your car. It does not react on:
• the fixed objects like trees, bridges or rocks,
• the vehicles on the road located farther than one adjacent lane,
• the other vehicles that move not in the blind spot of your car.
When a driver has turned on the turn signal and is going to drive off the lane to go to another one, the system warns a driver if any car is in the blind spot behind to avoid a collision. It allows the turn when the hindrance has passed.
4. Lane Departure Monitoring.
When activated, it preserves the car within the lane. It is enough only one visible road markup to keep it active. It the case when the markup is lost completely, or the car cannot recognize the road markup, the systems turns off and warns a driver about it. If a driver turned on the turn signal, the system would understand that there’ll be a shifting onto another lane, and it will deactivate. If a driver crosses the lane markup, there’ll be an audio signal and a flickering on the screen panel warning a driver to keep within the limits of the lane. The driver is free to override a system and to continue its work after a while when it becomes necessary again. In some models of 2016, this automatic system does not steer the wheel and only warns the driver about the crossing the lane with the vibration of the steering wheel.
5. Parking Assistant System.
It allows a driver to park a car within the available parking lot. The system first defines whether there is enough space on a lot for the specific car model and, if yes, sets the route for the best parking process. Using indications for a driver for steering, braking system and sound signals it makes it easier for a driver to park a car. It indicates the best positions and time to steer, brake, and go to complete the parking.
6. Park Distance Control. It gives the sound signals of proximity to the rear and front cars/objects of the car and reflects the video on the monitor from the back (and some models – from the front) to help a driver to park and leave the parking lot.
7. The Post-Collision Assistance. In Germany, there were about 25% of the cases when the car and/or passengers damage had been produced in the post-collision driving. To avoid this, after the collision has occurred, the vehicle defines the best trajectory to stop and/or to avoid further collisions.
8. Rear Traffic Alert. When leaving the parking lot driving backward, the system scans the area finding the approaching vehicles. If any, the car gives a signal to a driver to stop and becomes silent when the area is clean and safe again to drive.
