Form 101 – Proposal Improving Safety, Comfort and Efficiency of Convoy Vehicles through Novel Preview Control
1 Improving Safety, Comfort and Efficiency of Convoy Vehicles Through Novel Preview Control Fuel consumption and emissions are major concerns associated with heavy trucks, and both can be reduced if the trucks travel in a very closely-spaced platoon [1]. The military deploys trucks in closelyspaced convoys where the terrain can be highly variable and the drivers often inexperienced. Traffic acc...
متن کاملPreview estimation and control for ( semi - ) active suspensions
The dynamic behaviour of a vehicle (e.g. the dynamic tire forces, the suspension deflection, and the vertical acceleration of the sprung mass) can be improved significantly if the passive suspension is replaced by an active suspension with preview. Preview means that a priori information of the road surface is used in the control of the suspension. In this report, the rear wheels of the tractor...

متن کاملNeural Controller Design for Suspension Systems
The main problem of vehicle vibration comes from road roughness. An active suspension systempossesses the ability to reduce acceleration of sprung mass continuously as well as to minimizesuspension deflection, which results in improvement of tire grip with the road surface. Thus, braketraction control and vehicle maneuverability can be improved consider ably .This study developeda new active su...
متن کاملA case study towards the application of NMPC to a con- tinuously variable semi-active suspension
This paper presents a simulation-based study of the performance achievable by a continuously variable electro-hydraulic semi-active suspension system. By applying state-of-the-art dynamic optimization techniques, a direct optimal controller is developed for a nonlinear quarter car model that includes an identified semi-physical damper model. The direct optimal control approach offers an intuiti...
