2024 - STÄHLE Solution for EV Range Test on Chassis Dynamometers

The difficulty of driving a cycle is not necessarily to execute it optimally, but to repeat it with the same performance, again and again whatever the day, the environment, or the vehicle.

STÄHLE robots are recognized worldwide for delivering this quality. The performances measured according to the regulations of SAE J2951, are delivered as calculated values for ENERGY RATING and DRIVING INDEX. This technology is used by OEMs as well as by institutions. It makes verification traceable and, in certain regions, driving robots are part of the homologation process.

Electric vehicles require specific driving solutions. Increased pedal sensitivity and higher dynamics, coupled with hysteresis for energy recovery. The controller designed by STÄHLE meets each of these expectations. It offers functionality in repeating cycles. It is thus possible to repeat different cycles in a loop in order to test the vehicle under all its states of battery charge or temperature over long periods of time.

The integration of the HIOKI power analyzer and the possibility of full test report generations extends the scope of application and useability in testing.

2022 - For computer controlled driving of cars with drive-by-wire on proving grounds and test tracks

The SDrive system turns any drive-by-wire vehicle into an automated pathfollowing vehicle. In combination with our emergency brake actuator, driverless operation is secured.

The SDrive allows to integrate drive-by-wire vehicles into automated fleets and integration into open scenario fleets using the available interfaces.

2022 - new option for EV Power Report generation

The latest version of the AUTOPILOT software offers the new functionality for measuring, calculating and evaluating typical data of electric vehicles by integrating the HIOKI Power Analyzer. The acquisition of measured values supports 4 channels / measuring points, each with the relevant signals such as voltage, current, power, etc.

In post-processing, a detailed report is created for the entire test and for the individual evaluations of the sections/subcycles.

This report thus includes the complete assessments for the homologation & certification of electric vehicles.

2021 - for AVL customers

AVL, long-term partner and integrator of STÄHLE products, has just released a “Dynamic Steering Force Emulator” developed jointly with STÄHLE. This emulator makes it possible to simulate ADAS / AD tests on chassis dynamometers and powertrain testbeds with the AVL DRIVINGCUBE ™.

2020 - for SfpHybrid

The compatibility portfolio with navigation systems extends to products of the brand iMAR Navigation GmbH (St. Ingbert). In cooperation with DEKRA, Klettwitz, the performance of the iSWACO-ARGUS was verified on the Lausitzring in combination with our SfpHybrid robot.

Thus this interface option is now available in our program.

2020 - for SAE J2951 Evaluation

The latest version of the AUTOPILOT User Interface GUI EMISSION now includes the option of importing CarMaker measurement files directly.

This means that they can be conveniently visualized and analyzed in the offline graphics - the values for ENERGY RATING and DRIVING INDEX can also be calculated and exported in accordance with the specifications of SAE J2951.

2020 - in regard of ASAM Format

The latest version of the AUTOPILOT software makes it possible to save the measurement data directly in the binary ASAM format mdl4 after the end of the test/stop and to store it in a configurable location.

This means that the measurement data created by the AUTOPILOT system can be opened and evaluated in a standardized format by appropriate analysis tools and managed in a higher-level database.

2019 - Drive Quality Evaluation

The latest version of the AUTOPILOT User Interface GUI EMISSION contains, in the protocol of the cycle Recordings, the new output of the calculated values for ENERGY RATING and DRIVING INDEX according to the regulations of SAE J2951.

These rating numbers reflect the quality of cycle performance and are also listed in the offline cycle reports.

2019 - Tire Coefficients

The latest version of the AUTOPILOT User Interface GUI TRACKDRIVER can now calculate the tire coefficients ABC directly from a recorded log file. Hereby all lateral control relevant Vehicle model Parameter can be identified automatically and the Manual Input is limited to geometric Vehicle data.

2019 - The test field of possibilities is growing!

Our proven SfpHybrid is now also available for driving Manual Transmission vehicles. The Extension consists of an one-of-a-kind shift actuator and a clutch actuator - in combination with a newly designed brake actuator - which is mounted to the seat rail adapter, taking into account the driver footroom:
- thanks to SuperSeatPlate, the shift actuator can be fixed to the passenger seat within approx. 30 seconds and can also be easily converted for left- or right-hand drive vehicles
- due to their modular structure, the weights of the individual components of the actuator are under 13 kg

- known and proven functionalities / performance from our chassis dynamometer applications such as start-up logic, shifting sequences, safety monitoring

- no modifications to the vehicle necessary

- the shift actuator can also be used for shifting automatic transmission vehicles

- various other switching actuators (push button, rotary, etc.) can be added optionally.
