The VEHICO Steering Robot is a special development to stimulate test vehicles with any steering movements. Tests with automatic steering maneuvers becoming increasingly important, because by reproducible steering trajectories reliable measurement data for vehicle development can be derived. Not only the positioning precision is far superior to a human driver but also the operating speed. With steering angel velocities of 1200 °/s, even the required dynamics for the testing of electronic stability systems (FMVSS 126) according to the NHTSA is achieved.
The concept of the VEHICO Steering Robot appeals through the following features
-
no special steering wheel necessary
The vehicle's own default steering wheel can be used as well as a possibly existing measurement steering wheel. A special actuator steering wheel is not required. The steering robot is designed so that existing measuring equipment remain unaffected from the use of the steering robot and thus minimal extra expenses and integration costs occur.
The force application point on the steering wheel corresponds a normal driver so that even investigations at the steering mechanism lead to realistic results. The use of vehicle's own steering wheel also has advantages at the installation effort and security, because even the regular airbag control remains unaffected.
- quick and easy installation
A universal mounting concept consisting of bearing arms be attached to the windscreen over vacuum cups enables the rapid adaptation to different vehicles. Therefore no stiffening of the cabin occurs. The torsion stiffness or other vehicle properties are not or only minimally affected.
- driver's seat remains free
The actuator principle developed by VEHICO has the advantage that the driver even with built-in steering robot can normally use the vehicle. The driver's seat remains unaffected by the steering robot components. The control of the vehicle's own steering wheel is therefore still possible.
- scripting language for simple programming of steering profiles
In addition to many preconfigured standard steering profiles any steering profiles can be programmed using the VEHICO scripting language.
Therefore future standardized steering profiles can be implemented with the help of the scripting language as well as any own steering profiles. Even external trigger signals can be considered.
- record and replay steering maneuver
Due to the special design of the VEHICO steering robot it is possible to record the manually driven steering maneuver, and then replay them again. In replay mode the steering robot realizes exactly the previously recorded steering maneuver with highest precision.
- unique price / perfomance ratio
The VEHICO steering robot achieves a so far unique price / performance ratio with a very attractive price and simultaneously excellent features.
