One of the first commercial vehicle projects to benefit from the use of rFpro technology was a study for Hyundai, carried out by a team from Applus IDIADA, the state-of-the- “In the space of 10 days we were able to evaluate around 25 different vehicle configurations using three professional drivers,” explained Guido Tosolin, Applus IDIADA’s product manager, Chassis Development and Vehicle Dynamics Simulation. “More importantly, because of the high fidelity visual cueing using rFpro software, driver immersion was very convincing which led to good correlation between their subjective ratings and the objective data.” During the study, drivers correctly interpreted the direction and magnitude of various changes to kinematics, springs, dampers and anti-roll bars. An additional benefit was derived from the high volume of data produced, according to Tosolin. “For the first time, we have generated so much data that we are able to use statistical methods effectively to interpret the results,” he said. The IDIADA project is believed to be the first major application of a driving simulator to commercial vehicle chassis dynamics and required a suitable cabin arrangement and driving position to be effective. It also used rFpro’s own virtual Vehicle Dynamics Proving Ground which allows subjective and objective testing to take place just as it is done in real world track testing. “Our software is based on closing the loop as quickly as possible by providing very high bandwidth video and audio feeds to the driver and high bandwidth road surface detail to the vehicle model. This provides the realism necessary to achieve good correlation between driver perceptions and objective vehicle changes,” explained rFpro’s technical director, Chris Hoyle. “The quality of major design decisions in the early stages of a new vehicle programme can be greatly improved by supplementing engineering data with subjective ‘feel’ and in many areas human input is an essential ingredient. Using a driving simulator allows vehicle manufacturers to pull forward this activity, even though no physical prototypes exist.” rFpro works in partnership with motion platform producers, such as MTS and Ansible Motion, to deliver a turn-key system, if required, and the software can wrap around vehicle models from all the popular modelling environments, including Dymola, SIMPACK, CarSim, CarMaker, Simulink, AVL-VSM, LMS Virtual.Lab Motion, VI-Grade and C/C++. Leading global supplier, MTS Systems Corporation, recently selected rFpro software for its new VDS (vehicle driving simulator) in order to provide an off-the-shelf driving simulator with cutting-edge dynamic performance. About rFpro rFpro is a specialist software company that has developed driver-in-the- To deliver complete DIL simulators for the engineering development of vehicle dynamics, and the control systems and active safety systems that affect vehicle dynamics, rFpro works in partnership with motion platform providers such as, Ansible and MTS. The company’s products can wrap around vehicle models from all the popular modelling environments, including Dymola, SIMPACK, Simulink, AVL-VSM, CarSim, CarMaker, LMS AMESim, VI-Grade and C/C++.
