Study on Dynamic Responses of the Vehicle Handling Models with a Speed-sensitive Hydraulic Power Steering System 2007-01-4239

In this work, a speed-sensitive electronically controlled hydraulic power steering (ECHPS) system is analyzed. The use of an electro-hydraulic transducer and a hydraulic bypass in parallel with the hydraulic power steering system makes it possible to vary steering effort with vehicle speed. In order to research the dynamic responses of the vehicle with the ECHPS system during maneuvers, an ECHPS model and a vehicle handling model are developed. These models can be used for performance evaluation of the steering motion of the vehicles, and also for the design of new power steering system.
