Control of Steering Effort and Response for Power Steering of Commercial Vehicles 852250

The sensitivity of steering increases as the vehicle speed rises. It requires a driver to make different steering maneuvers at high speed zone from that at low speed zone. In order to reduce the difference and to have a better steering “feel” for the driver, the characteristics of steering should be studied from both “the vehicle lateral movement corresponding to steering effort” and “the time lag of the vehicle lateral movement to steering effort”. And both should be decreased as vehicle speed rises. This paper explains how the above conclusion was reached through the development of engine/vehicle speed sensing power steering for commercial vehicles.
