The most advanced safety systems and driver assistance for affordable car The new system – optimized security and convenience The new driver assistance systems – emergency braking system with multiple collisions. The Volkswagen Group is the only global automaker, establishing a system for compact cars as standard – Proactive occupant protection system, standard with electronic differential lock XDS (as in the previous generation Golf GTI); Adaptive Cruise Control ACC in combination with the Front Assist and Brake function at low speeds, City Emergency Braking; warning system output of occupied bandwidth Lane Assist; detection of driver fatigue, feature recognition of road signs and the latest generation of ParkAssist with function Omnidirection OPS (360 degrees), as well as an automated lighting system Light Assist and Dynamic Lighting Dynamic Light Assist. In addition, the car used and innovative solutions such as the steering progressive characteristics (for optimization of performance and increase the level of comfort), and select a profile system with five driving modes (Eco, Sport, Normal, Individual and Comfort combined with DCC). Driver assistance systems – automatic protection Emergency braking system with multiple collisions. The new advanced emergency braking system with multiple collisions, implemented in Golf, has received an award for innovation in the field of security from the largest automobile club in Germany (ADAC). Principle: research on road traffic accidents (RTAs) have shown that about one quarter of all accidents that resulted in injury occurs involving multiple vehicles, which means that the initial collision results in the next. Emergency braking system with multiple collisions automatically activates the brakes when the car is involved in an accident, which can significantly reduce its residual kinetic energy. Activation of the emergency braking of multiple collisions is based on the determination of the parameters of the initial collision with the air bag sensors. Decelerate the vehicle with emergency braking when multiple collisions limited ESC control unit within the maximum permissible 0,6 g. This restriction applies braking, carried out under the control function Front Assist. Driver’s ability to drive a car is maintained even when activated automatic braking. The driver can inhibit the action of emergency braking in multiple collisions, for example, when the system detects signs of his actions to accelerate the car, it goes off. The automated system is also disabled when the driver is making an emergency stop with the brake force, resulting in the rise of high deceleration. Brake Assist is active in multiple collisions to those long as the vehicle speed drops to 10 km / h This residual speed of the vehicle can be used to send the car to a safe place after braking. Proactive occupant protection system (PreCrash). Of proactive occupant protection is a typical example of the transfer of technology, commonly used in cars “premium” class, in the compact segment.

Volkswagen has implemented a system of proactive protection

For the first time Volkswagen has implemented a system of proactive protection for the driver and passengers in the model Touareg. Now this system is presented in the Golf, so this car is one of the few in the class model, is equipped with this safety system. When the proactive occupant protection system determines the probability of collision, for example, when braking with Brake Assist, to seat belts for driver and front passenger pretensioners automatically activated to provide the most effective action cushions and seat belts themselves. When it detects a critical situation with the loss of stability, such as understeer or oversteer intervention of ESC, close the side windows (except when the window slightly ajar) and sunroof. This is because the optimal efficiency of front and side airbags is achieved with a fully closed windows and hatch. Adaptive cruise control. Until now, adaptive cruise control (ACC) had the advantage of a higher class cars, such as the Volkswagen Passat CC and Phaeton. Thanks to the new generation Golf ACC system appeared in the compact class. The system uses a radar sensor installed in the front of the car. ACC is active in a range of speeds from 30 to 160 km / h for cars with manual transmission, and from 0 to 160 km / h for cars with manual transmission DSG (dual-clutch). On cars with a manual transmission DSG intrusion adaptive cruise control is dependent on the situation, when you need to slow the car down to a stop, and in a mode of motion with constant stops in heavy traffic system shuts down. ACC support the selected driver speed and distance, enabling automatic acceleration and braking when driving in traffic. The nature of the system can individually change a program of management in selecting the profile driver that the new Golf is available as an option. Function of distance control Front Assist. Front Assist function works like cruise control ACC and is based on the testimony of a radar sensor located in the front of the car, which continuously monitors the distance to the vehicle ahead. Even when the cruise control is disabled, Front Assist helps the driver in critical situations, carrying out pre-deployment training brake and warning the driver visual and audible warnings about the need for any action. If the driver brakes not efficient enough, the system automatically increases braking force to prevent a collision. If the driver does not react to the warning served, Front Assist system automatically reduces the speed of the vehicle in such a way that, under optimal conditions, the rate of collision is minimal. The system also alerts the driver if the car is too close to the car going forward. New brake function at low speeds in city traffic City Emergency Braking function is part of the Front Assist. It is intended for scanning area in front of the car, with the radar sensor.

The new system operates at speeds below 30 km / h In case of danger of collision with a parked vehicle in front, or in the absence of reaction on the part of the driver’s brake system is being prepared in the same manner as in the action of Front Assist. If necessary, the system initiates the City Emergency Braking brake system in order to reduce the severity of the collision. In addition, if the driver is not strong presses the brake pedal, the system applies full emergency braking. The detection system of driver fatigue. The system, first implemented in the output model Passat, allows to determine the loss of concentration and alert the driver to an acoustic warning lasting five seconds. On the instrument panel displays a visual warning of the need to rest. If the driver does not stop traffic for 15 minutes, the warning appears again. At the beginning of each trip, the system analyzes a number of factors, including the nature of the impact of the driver on the steering wheel. Further, during the movement of the system continuously monitors parameters such as the angle of the steering wheel. If the impact on the steering wheel is different from the settings stored in the system beginning of the trip, it takes the driver audio and visual warnings. Regardless of the results of monitoring, if the system is active, it is recommended to take a break in the movement of every four hours of continuous motion. Control system exit from the band Lane Assist. Control system exit from the band with a front camera intervenes in driving and has extended functionality and adaptive control car while driving on the strip. If desired, the system, which was first used in the model Golf, now can always help the driver to drive within the selected band with an increased level of comfort. In addition, if necessary, the system Lane Assist corrects the trajectory of the vehicle using a steering: as soon as the system detects that the vehicle is outside the band occupied by the driver, or carries without rebuilding the direction indicators, it is by acting on the steering, the car gently moves in the opposite side. System to improve the level of comfort – steering, braking, visibility steering with progressive characteristic.

In a conventional steering system uses a constant ratio, but in the new Golf has an optional steering progressive characteristic ratio. This will reduce the steering effort when making maneuvers at low speeds and in parking lots. When driving on country roads with many bends driver noticed improved dynamic performance thanks to a closer interaction with the vehicle and the driver’s lower corners of the steering wheel. Technically steering with progressive characteristic is different from ordinary variable tooth pitch rack pinion steering with a more powerful electric motor. Functional differences: in contrast to the constant steering gear ratio, which is always a trade-off between dynamic performance and comfort, in this case the tooth pitch steering rack changed simultaneously with the change of the angle of the steering wheel. As a result of the transition from the regime with less direct steering response in the “near-zero” zone (motion in a straight line) to a regime with a more direct response at high angles of rotation, when, as described above, it becomes more “spicy” in situations that require dynamic maneuvers. Thus, car parking becomes more comfortable, because the angles of the steering wheel are reduced. For a long time the gearbox ratio was associated exclusively with the power steering, but the settings of the steering gear can be in a very narrow range, so that the driver did not have negative feelings to transient conditions. In the case of a steering system with a progressive characteristic of the new Golf everything is completely different: a combination of progressively changing the gear ratio and adjustable steering electromechanical actuator, which is used in the Golf for the optimization of control, allows you to conduct a more sporty steering and also practical in daily trips . Electromechanical parking brake. For drivers of larger vehicles Volkswagen, such as the Passat and Tiguan, electromechanical parking brake is already regarded as conventional equipment. Now a parking brake will be present in the cars Golf.

Instead of the brake lever using the main switch, and the switch Auto Hold, located on the central console. Electromechanical parking brake has a number of advantages: free space on the center console, which previously held the traditional parking brake lever, the brake is automatically turned off when pulling away, making it easy hill start. Last, but not least – the function Auto Hold, preventing unintended car slide after shutdown. Dynamic lighting Dynamic Light Assist. With the camera on the windscreen, the system analyzes the motion of the counter and the associated transportation. Based on these data, the system automatically turns the head lights at speeds over 65 km / h Principle of Dynamic Light Assist: using front camera system obscures modules beam bi-xenon headlights with dynamic cornering lights only in areas that are not being closed may dazzle other road users. This feature is technically implemented as rotary screen with openings between the reflector xenon optical element and the lens. Along with the ability to rotate in the horizontal plane of the module, and each module separately, the screen helps to mask the light source and to avoid blinding drivers, moving in opposite directions and passing. System Light Assist. For vehicles not equipped with dynamic cornering lights, available in the basic version of automatic main beam control. Light Assist system analyzes the flow of cars moving in opposite directions, and passing through a camera mounted on the windshield and automatically controls the switching on and off beam (at a speed ranging from 65 km / h). Recognition of road signs. Traffic Sign Recognition system was first introduced in the model Phaeton. The new Golf, it will operate in conjunction with the satellite navigation system.

If the camera is mounted on the windshield near the rear view mirror, detects speed limit sign or overtaking is prohibited, these characters (up to three at a time) are displayed on the instrument panel and display navigation system. Will be displayed and additional information, and the signs will be presented in a logical order: those that operate continuously (for example, the speed limit of 130 km / h) will be shown in the first place, and those that operate under certain conditions (for example, limiting to 80 km / h, operating in wet weather) – in second place. If rain sensors determine that it begins to rain and the effect the sign comes into force, it is moved to the first position mark “in the rain.” Parking Assist Park Assist 2.0. The latest version of Active Parking Assist is now not only makes it easier to “parallel”, but the “perpendicular” parking performed in reverse at a right angle to the road. In addition, the system is equipped with Park Assist 2.0 braking function and provide space for the exit of the car. The system can be activated at speeds up to 40 km / h by pressing a button on the center console. With the turn signal switch driver chooses which side it will park your car. If the Park Assist system with ultrasonic sensor detects enough space for parking (distance ahead of the vehicle and may be followed by a total of 40 cm), begins with a semi-automatic parking system: the driver only has to turn on a reverse gear and press the gas pedal and brake. The car will take care of the steering wheel. Audible warnings and visual information displayed on the multifunction display, will further assist the driver to navigate during the maneuver. In the event of a threat of collision system itself uses the brake system of the car.
