Passengers that everyone likes to have

Driver assistance programs such as ABS or ESP increase safety when driving in a car. Some are now available as standard in almost every new car. Others, such as lane change assistant or night vision assistant are initially included in just few models. We will introduce you to the most important systems.

ESP - Electronic Stability Program

If a vehicle threatens to spin, the ESP keeps the car on course by deliberately braking individual wheels and thus gives the driver control. Spinning out is one of the main causes of serious traffic accidents. ESP can prevent 80 percent of these. According to a Volkswagen study, the number of vehicle occupants killed in traffic accidents could be reduced around 25% if all vehicles were equipped with ESP.

Traction control

Traction control regulates engine performance when too much gas causes the wheels to spin. The traction control intervenes when needed in the engine management, throttles the gas supply and brakes the driven wheels until they have enough grip again and the maximum power can be put on the road. Traction control also enables optimal acceleration with less tire wear. 

ABS - Anti-lock Braking System

ABS is a braking aid that prevents the wheels from locking when braking. The car remains fully steerable despite maximum possible braking effect so that the driver can avoid possible obstacles. An electronic control monitors the speeds of all four wheels. If one of those wheels threatens to block, the braking force is reduced. Thus, the braking distance shortens in as blocking wheels extend by sliding on the road in most cases. 

Lane Change Assistant

If you look at the lane change only briefly in the mirror, you can quickly overlook someone. The lane change assistant warns you of vehicles in the blind spot. It keeps an eye on the area next to and behind the vehicle at all times and helps to reduce the risk of accidents during overtaking and lane changes. 

Cruise Control

Driving in dense traffic and maintaining the correct safety distance to the vehicle in front requires high concentration and attention from the driver. The distance controller automatically adjusts the safety distance and automatically adapts the speed to the traffic flow. This allows the driver to better focus on current traffic. 

Night View Assistant

Poor visibility in the darkness and back-lighting often results in accidents because dangers are often detected too late. The Night Vision Assistant extends the field of vision of conventional headlamp systems. Two infrared spotlights on the front of the car illuminate the street for up to 150 meters. An infrared camera uses light invisible to the eye to project a high resolution black-and-white image onto a monitor in the dashboard. Thus, the driver gets a better overview of the traffic situation at night than by the beam alone. 

Early Warning System

The tire manufacturer Continental is developing an early warning system for roads. A combination of sensors is designed to detect both wet and black ice: an optical sensor perceives ice and moisture based on the reflection of the road surface. A laser scanner recognizes raindrops and snowflakes up to 100 meters away. Sensors on the tires sense the danger. In addition, two thermostats measure the temperature of the road surface and the ambient temperature. All available information is then linked to the data from the ESP. A processor then calculated the adhesion of tires and the road. 

Here for your safety

TUV NORD is continuously working on optimizing the review of electronic driver assistance systems during the main inspection. We develop and test technologies with which we can efficiently check all safety-related control units and intelligent sensors on the vehicle via an interface.
