Evaluation of fault handling and detections strategies using the KTH Research Concept Vehicle (AZ Fault Test)
|Coordinator||KUNGLIGA TEKNISKA HÖGSKOLAN - Institutionen för farkost och flyg|
|Funding from Vinnova||SEK 375 000|
|Project duration||September 2015 - October 2016|
Purpose and goal
1.Study the effects of fault-tolerant strategies on driver and vehicle performance. 2.Validate simulation and moving base driving simulator results so far gained in the FT_HEV and EVERSAFE projects. 3.Evaluate new control strategies using torque, steering and combined control strategies. 4.Test performance and actuator limits of the RCV.
Expected results and effects
Goal 1: Have studied the effects of fault-tolerant control strategies on vehicle performance. Was not able to set up a test with multiple drivers. Goal 2: Have validated the simulation and tests done regarding vehicle performance only and not using drivers in the loop. Goal 3: Have evaluated new control strategies using only torque and not steering or combined strategies. Goal 4: Have tested and generated new data on performance and actuator limits of the Research Concept Vehicle platform.
Planned approach and implementation
This project tested theories developed during and after FT_HEV and EVERSAFE in real-life situation giving a better understanding of the area. The tests also increased knowledge of the RCV performance that will be used to update the virtual RCV model for further research. Two test expeditions have been conducted at AstaZero, each beeing two full days. This have generated a lot of new data that were analysed and the results previously seen and reported in Wanner et. al. 2015 have been partly validated, as seen in results and expected effects.
