Driver assistance systems save lives. When driving for a long time, the driver can be alerted by a sound warning or a coffee cup icon displayed in the dashboard. According to a study by Bosch on the various newly registered main types of vehicles in Germany in 2013, nearly a quarter of the 2.95 million newly registered vehicles (680,000 vehicles) are equipped with a driver fatigue detection system that enables the driver Fatigue Driving and may cause a warning before it causes an accident. This allows driver fatigue detection to become the most equipped driver assistance in the new car.

The importance of driver assistance systems, the "invisible passenger," is on the rise. Gerhard Steiger, President of Chassis Control Systems at Bosch, said: "The development of a driver assistance system is an important step toward eliminating traffic fatalities and achieving the vision of a" zero-accident "drive." To this end, the European Union New Car Crash Test (NCAP) Sexual emergency braking systems and lane keeping assist systems are included in the new grading standards, thereby increasing the availability of both systems. And this trend has also affected the key component of the driver assistance system - sensor production. According to Gerhard Steiger, "Bosch expects to ship more than two million radar and video sensors in 2014, more than double last year." Here are the top-of-the-line driver assistance systems in six German new cars by equipment availability:

23% of new cars equipped with driver fatigue detection system

A brief drowsiness, lack of concentration and fatigue in the driver's driving can easily lead to traffic accidents. Now, all these signs can be detected in advance by driver fatigue detection. When the driver is distracted, steering accuracy is reduced and the frequency of the fine-tuning of the steering wheel is increased. Bosch's driver fatigue detection system continuously analyzes the driver's steering behavior and uses steering angle sensors or electric steering to identify typical fatigue modes. The system can also record any slight burst of steering action. By combining more parameters such as accumulated driving duration or driving time information, the system analyzes the level of fatigue identified and then sends audible or visual signals informing the driver to take a break and avoid drowsiness. Twenty-three percent of all newly registered new cars in Germany in 2013 were equipped with fatigue detection systems.

20% of the new car is equipped with intelligent headlight control system

The vehicle is equipped with a smart headlamp control system for better visibility. When driving at night or in a tunnel, this assistance system automatically turns on or off the low beam as required. If the intelligent headlamp control system does not find the car in front of or opposite to the car, it will automatically switch the high beam (such as the vehicle is not in the construction area). Moreover, the intelligent headlamp control system can adjust the headlamps according to the direction of the road or repeatedly switch between low beam and high beam. As a result, the system ensures optimal lighting in this way, while avoiding dazzling of other road users. 20% of the newly registered vehicles in Germany in 2013 were equipped with intelligent headlamp control system.

11% of new cars equipped with automatic emergency braking system

Rear-end accidents are one of the most serious road accidents, especially when it comes to pedestrians or cyclists. Automatic emergency braking system to avoid such accidents or reduce the risk of accidents. Once the system detects an obstacle in the road ahead, the Auxiliary Function pre-brakes the emergency brake or automatically brakes automatically when the driver can not respond. Such predictive pedestrian protection is widely recognized as a sine qua non for the five-star achievement of the EU New Car Crash Test (NCAP) since 2016. If all cars in Germany are equipped with an automatic emergency braking system, up to 72% of rear-end collisions involving personal injury can be avoided. In 2013, 11% of newly registered German vehicles were equipped with this system.

10% of new cars are equipped with lane assist systems

Of the newly registered vehicles in Germany in 2013, 10% were equipped with lane assist systems. Lane assist function consists of three systems. Lane departure warning system to prevent accidents by warning the driver. For example, driver's attention may be alerted by steering wheel vibration when the driver is unconsciously deviating from the lane. Lane Keeping Support The system reverses direction in a gentle and steady way when the car is too close to the lane edge to further prevent accidents. Lane lane assist system monitors the area on the side of the car and behind the car. When the rear of the car quickly approached or appeared in the blind spot, the warning lamp on the exterior rearview mirror will warn the driver. According to data provided by the German Institute for Advanced Accidents (GIDAS), lane keeping support systems prevent up to 28% of traffic accidents caused by accidental lane departure.

4% of new cars equipped with road sign recognition system

Of the newly registered vehicles in Germany in 2013, 4% were equipped with road sign recognition systems. This feature makes it easier for pilots to walk through the "road markings jungle", both in the speed limit zone and in the no-go zone. The video camera reads the traffic signs and displays the information in the dashboard with the symbol. In addition to systems specifically designed for on-board deployment, Bosch has also developed a free road sign identification solution for smart phone users, myDriveAssit. The app uses smartphones' built-in cameras to identify road signs and is available on Apple's App Store and Google Play.

4% of the new car is equipped with adaptive cruise control or stop-type adaptive cruise control system

The Adaptive Cruise Control (ACC) works in conjunction with a radar sensor to keep driving safe with the car in front of you even in crowded traffic. Through automatic acceleration and braking, the system adjusts the vehicle speed to traffic flow, while ensuring smooth travel and fuel economy. Stop-and-go adaptive cruise control reduces vehicle speed or stops the car completely in the event of a traffic jam. If equipped with an automatic transmission, the system will restart when the vehicle is restarted after a brief stop. Ultimately, the driver can be freed from boring driving and stay awake for a longer period of time. Of the newly registered vehicles in Germany in 2013, 4% were equipped with adaptive cruise control or stop-and-go adaptive cruise control. By providing more cost-effective sensors such as mid-range radar sensors, Bosch continues to increase market penetration and lower the price of related system solutions to meet the broader technological needs, including small and compact models.

As one of the largest suppliers to the automotive industry, Bosch offers a full range of driver assistance systems. The anti-lock braking system (ABS) and electronic stability program (ESP) developed by the company laid a solid foundation for the continuous reduction of traffic accidents. In addition, electronic stability programs are also basic technologies for developing autonomous driving. Vehicles continue to use sensors to learn step-by-step how to "observe" and perceive the environment, and over the years, Bosch continues to provide the necessary radar and video sensors. In addition, a powerful computer can think like a good driver and ensure that the driver assistance system responds quickly.
