Active Steering Control to Enhance Narrow Tilting Vehicle Stability
James RobertsonCentre for Power Transmission and Motion Control
University of BathBath, United Kingdom
Supervisors: Dr J. Darling, Prof A. Plummer
What Are Narrow Tilting Vehicles?
Narrow vehicles which tilt during cornering to maintain stability
Can provide a safe low carbon alternative to existing personal transportation methods. Particularly suited to urban environments
The C.L.E.V.E.R Vehicle: Tilting system developed by the University of Bath
The C.L.E.V.E.R Vehicle Crash Test: 3* NCAP Equivalent
Direct Tilt Control (DTC)
Steering Direct Tilt Control (SDTC)
Hydraulic Active Steering System Response
Experimental Results
Steering Response Stability Improvement
Wheel Load Variation Reduction ≈ 30% at 7.5m/s
Steer Input Severity Reduced
UKACC PhD Presentation Showcase
Conclusion and future work
Conclusions Active steering improves vehicle roll stability Steer inputs and can be delayed or countersteering action
introduced Moment generated by DTC actuators reduced
Further Work Improvements to the lateral acceleration estimation model Further experiments to establish system performance in a
variety of manoeuvres and operating conditions
