What Are Narrow Tilting Vehicles? Narrow vehicles which tilt during cornering to maintain stability The C.L.E.V.E.R Vehicle: Tilting system developed by the University of Bath 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 Crash Test: 3* NCAP Equivalent
Steering Direct Tilt Control (SDTC) Hydraulic Active Steering System Response
Experimental Results Steering Response Stability Improvement Steer Input Severity Reduced Wheel Load Variation Reduction ≈ 30% at 7.5m/s
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 UKACC PhD Presentation Showcase
