A New Generation of ADMA Gyro Systems for Measuring

Press release

January 2013

Small, compact and unique worldwide:

A new generation of ADMA gyro systems for measuring

the vehicle dynamics with an output rate of 1000 Hz

For more than a decade, GeneSys Elektronik GmbH in Offenburg has produced a GPS-aided gyro system named Automotive Dynamic Motion Analyzer, ADMA in short. It is developed and produced specially for measurements of vehicle dynamics and driver assistance parameters in the automotive sector. With a significantly enhanced computing performance, interface extensions and an improved real-time capability, the new generation of ADMA meets customers' needs worldwide. Achievable previously was a maximum output rate of 400 Hz with limited data records. ADMA 3.0 now allows an output rate of 1000 Hz with unlimited data records and a data latency of less than 1 millisecond! Besides CAN-bus interfaces, the device now includes new Ethernet interfaces for data output, configuration and updating. Measurement data are available for an evaluation in real time, enabling a user access at very high data rates.

Driver assistance systems are becoming increasingly significant in automotive engineering, due to their ability to further enhance the safety and comfort of modern vehicles. When measuring the vehicle dynamics in the automotive sector, the accurate determination of all movements is an important requirement for it. The ADMA permits a high-precision dynamic measurement of all states of motion such as acceleration, velocity, position, rotational speed, position angle and slip angle of the vehicle. GeneSys Elektronik GmbH developed the first ADMA (Automotive Dynamic Motion Analyzer) gyro system specially for such applications already more than a decade ago.

With the new ADMA 3.0 generation, the data output rate has been increased to 1000 Hz by using a very fast signal processor and a modern FPGA. A total of 3 Ethernet and 5 CAN-bus interfaces allow a rapid data transfer, the various Ethernet interfaces serving for data output, configuration and updates.

In practice, such high data rates in real time prove particularly valuable in developing driver assistance systems. For example, the position of a vehicle moving at 100 km/h can be resolved to less than 3 cm. Thus, many new possible applications with even more accurate results can be realized.

Another positive feature in addition to the extremely high sampling rate is the ability to transmit GPS correction data via Ethernet. In the case of distance measurements previously, for instance, it was necessary to equip each participating vehicle with a receiver for DGPS correction data. With the latest generation of ADMA, it suffices to simply link the target vehicle to the correction data service. All other vehicles can be connected free-of-charge via WLAN to the target vehicle. This saves time and additional connection costs.

An enhanced computing power with a very fast DSP in conjunction with a modern FPGA permits relative data calculations directly inside the newly developed ADMA. The target vehicle sends its position data to the following Ego vehicle via WLAN. The calculations of the distance, the relative speed and the position angle with respect to the Ego vehicle still take place inside the ADMA 3.0, the data being made available online right away. Besides serving for the classical data output, the Ethernet interface is also a convenient and simple means of configuration and firmware upgrade. A linkage to a robot driver for an autonomous vehicle guidance is still possible.
