Hella new active safety systems
Ultrasound-based electronic parking assistant
And an ACC 24 GHz sensor in development

The parking assistant from Hella works reliably in one go.

Hella is the first supplier to received three orders for series production of driver assistance systems in international markets, with series production to start shortly:

- Lane change assistant with 24 GHz radar sensors for a German car manufacturer,
- an adaptive cruise control (ACC) system based on infrared sensors, and
- a rear view camera system for a US manufacturer.

In the case of an impending lane change, the lane change assistance system determines the distance and relative speed of other vehicles and generates, if necessary, an optical, haptic or acoustic warning.

New is Hella’s electronic parking assistant which enables the driver to automatically, comfortably and safely back into even narrow parking spaces. An ultrasound sensor automatically measures the length and width of a parking space while driving alongside it, even taking account of curb stones. If the parking space is large enough, the parking process may be started. The driver only operates the accelerator and brake pedals, while all steering is done automatically.

The focus is on the large-scale introduction of driver assistance systems for sustained improvement of road traffic safety. “A prerequisite to this is that the price-benefit ratio is acceptable to car manufacturers and drivers,“ explained Dr. Tilman Seubert, head of Hella’s electronics preliminary development department. “Both with the 24 GHz radar sensor which can be used in various applications, and the ACC system based on infrared, we offer robust technology at a price level that does not stand in the way of wide-spread use in all vehicle classes.“

At present, Hella engineers are developing an ACC system with a 24 GHz radar sensor. In contrast to the existing infrared technology (LIDAR), the system is designed for lower and medium speed ranges. Moreover, Hella is working on an additional function of the infrared-based ACC: the “automatic emergency brake“.

The continuous development of driver assistance systems at Hella is in line with the European Union’s campaign for road traffic safety. According to investigations of the Federal Ministry of Transport, more than fifty percent of all accidents could be influenced by preventive measures.
