The progress made in vehicle development, as well as the increasing demand and complexity of vehicle testing over the last years have led to the requirement of new approaches for technology in driving aid systems for testing and certification.
Our ErgoDrive Professional for road simulation has an ergonomic human-machine interface and can be operated as a stand-alone unit or as an integrated component in an entire automation process.
The typical application examples in the dynamometer or climatic wind tunnel are:
- emission certification
- fuel consumption measurement
- transmission optimization
- cooling capacity study
- braking force measurement
Like on a real road trip, the test driver is integrated in the driving process as a controller of the system with visual feedback.
The ErgoDrive Professional has been ideally adapted to the ergonomic requirements of the driver and the testing task. This was mainly done for standard applications like emission certification, as well as for new applications such as transmission and brake system optimization. As a result, the test driver can fulfill his tasks for long periods in a concentrated but relaxed way.
The visualization offered through ErgoDrive has been enhanced with important functionalities without having to abstain from its standard functionalities and interfaces. The GPS recorder of the ErgoDrive Professional makes it possible to train a driver's aid system. Reality can be reproduced in an existing system through the recording of real road and environmental data in the driver's aid system.
ErgoDrive is currently being used by many well-known manufacturers in the German automotive industry.
RDE driver’s aid for road trips
The RDE driver’s aid for road trips simplifies the handling and evaluation with mobile measuring and test systems, helping to identify potential exhaust gas examination errors at an early stage and to avoid manipulations as best possible.
The module is designed to assist the user on road trips with regard to exhaust emissions under real operating conditions. Daimler is already using the RDE driver’s aid in practice. The measurements of the test facilities and the subsequent evaluation of the data and calculation of the mean values by the RDE driver aid allow the investigation of exhaust systems in real operation on the road and to achieve meaningful results under real conditions. Faulty laboratory values on reel chassis dynamometers are now an issue of the past.
In addition, the RDE driver’s aid allows the early detection of inadmissibly used shutdown devices in any vehicle models.
Thanks to the user-friendly navigation function, a uniform navigation profile can be maintained during real-world conditions during the measurement so that a comparison of data is possible.
The advantages of the RDE driver’s aid at a glance:
- Simple and fast calculation of the mean values based on their measurement data
- Detailed evaluation
- Uniform navigation profile for real road conditions during your measurements (navigation function)
- Early detection of tampering and detection of inadmissible shutdown devices in any vehicle models
- Individual adjustments as required
The RDE driver’s aid is used together with the measuring and test systems. During the measurements, the RDE driver’s aid ensures that the test driver keeps the predefined distance in practice. The routes can be determined via the navigation function, taking into account the specifications of the applicable exhaust emission cycles (for example, ECE driving cycles). These are subdivided into defined sections of the route in the city, country, motorway.
In addition to the navigation function, the RDE driver’s aid also monitors whether the predetermined average speed is maintained for the defined section.
The target speed for the remaining section of the route is constantly determined and displayed to the test driver by means of a slider in the left-hand area of the driver’s aid screen. If the slider leaves the defined range, the test driver will be warned.
For the individual sections (city, country, motorway) predetermined average speeds are determined. On the basis of the exhaust emission measurement technology used by vehicle inspectors, the values given by the manufacturers can then be checked.
The actual speed from the vehicle can be determined by means of the GPS signal or can also be read in via the ODB2 interface or the CAN bus available in the vehicle.
Representations in the vehicle
The user-friendly operation of the RDE driver’s aid makes it possible to install the module software on e.g. a Panasonic Toughpad and then attach it to the vehicle with a universal windscreen mount. In this way, the user can react flexibly to changes and work in a timely manner. Further presentations will be adapted to your requirements.
