1. Active Steering Control to Enhance Narrow Tilting Vehicle Stability James Robertson Centre for Power Transmission and Motion Control University of Bath Bath, United Kingdom Supervisors: Dr J. Darling, Prof A. Plummer

2. 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

3. Direct Tilt Control (DTC)

4. Steering Direct Tilt Control (SDTC) Hydraulic Active Steering System Response

5. Experimental Results Steering Response Stability Improvement Wheel Load Variation Reduction ≈ 30% at 7.5m/s Steer Input Severity Reduced

6. 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
