General information

Since the construction of the first automobile more than one hundred years ago, vehicle technology has increasingly been further developed and perfected. Today, the automobile is recognized as an integral part of the complete system of driver, environment and traffic. Strict noise- and pollutant-emission limits as well as the ever-increasing traffic density necessitate new concepts and methods for the vehicle and traffic of the future. These concepts and methods must find ways to solve the conflict between demand for increasing mobility and the call for the lowest possible accident rates and environmental impact. The driver assistance department takes on these challenges in research and development.

Automated Driving

In the driver assistance department new vehicle technologies are researched and developed in their own surroundings. The department's primary goals are the research and analysis of new systems from the area of driver assistance and active safety. New technologies are evaluated with respect to their potential to improve traffic safety, to reduce pollutant- and CO2-emissions, to increase driving comfort and to improve traffic flow. In the past, examples of achieved projects have included:

  • Series development of ACC for commercial vehicles and safety systems built on it
  • ACC Stop&Go und lane keeping controller
  • Algorithms for collision mitigation and collision avoidance
  • Forward-looking powertrain control for conventional and hybrid propulsion concepts
  • Communications-based traffic assistance
  • Development of a communications-based intersection assistants
  • Lane-change assistance
  • Semi-autonomous parking assistance
  • Construction of test vehicles and prototypes

Testing of new vehicle systems and sensors

One focus of the work is the analysis and testing of new vehicle systems and sensors in road tests. A test procedure developed for the automobile industry allows the contact-free measurement of separation distance and evaluation of speed difference using different sensor concepts. The test procedure coveres both road tests in moving traffic on the motorway as well as stationary tests on a test track and in reproducible weather conditions. For this, a special test suite was developed, consisting of mechanical and electronic devices as well as standardized targets for the distance measurement. Methodical test procedures have been developed for assistance systems that allow both objective and subjective evaluation of the systems. The following is an excerpt of available test procedures:

  • Standard test for environment sensors of European vehicle and sensor manufacturer
  • Standard test for ACC, ACC Stop&Go systems
  • Validated test procedures for pre-crash systems and active pedestrian protection
  • Standard tests for collision-warning systems
  • System tests for lane departure warning, traffic sign memory and ACC Stop&Go
  • Standard tests for camera-based high-beam assistants
  • Standard tests for radar and lidar sensors for pre-crash applications

Traffic flow simulation with PELOPS

In addition to road tests, simulation is an important tool for the development and assessment of driver assistance systems. Thus, the traffic flow simulation program PELOPS has been under development since 1990, in cooperation with BWW AG. The program enables a detailed simulation of the driver and vehicle in a realistic traffic environment. PELOPS was introduced within the framework of the European research program Prometheus for the analysis and development of telematic systems. Subsequently, PELOPS was drawn on for the development and analysis of driver assistance systems. Another usage of PELOPS involves the optimization of traffic flow as well as the decrease in fuel consumption through the adoption of driver assistance systems. Today, PELOPS is a powerful development tool. Through various interfaces, existing control algorithms in the source code can be implemented exactly like control modules or entire vehicles (Software- and Hardware-in-the-Loop). In the past, PELOPS has been licensed to diverse OEMs and suppliers.

The analysis and modeling of driver behavior is an important aspect for the understanding and layout of driver assistance systems. To this end, methods are being developed for recording driver behavior in the driving test and in the driving simulator. A high-resolution driver model for path guidance is available for this purpose. This has been developed in cooperation with BMW AG.

The driver assistance department develops complete systems, from the initial ideas to the final testing in the vehicle and futhermore offers targeted support for system development to its customers.
