Abstract
A method is provided for assisting a driver of a vehicle during operation by providing the driver with a desired steering feel. The method includes determining a desired steering device guiding force including a part representing a desired friction in a steering arrangement, and providing the driver with the desired steering feel based on the determined steering device guiding force.
Claims11
A method for assisting a driver of a vehicle during operation by providing the driver with a desired steering feel in a mechanical steering arrangement, where the mechanical steering arrangement comprises a steering device, at least one ground engagement member, and a mechanical connection between the steering device and the at least one ground engagement member, comprising the steps of
- determining a desired steering device guiding force comprising a part representing a desired friction in a steering arrangement, wherein the desired steering device guiding force is determined by at least one predetermined friction model of the desired friction in the vehicle steering arrangement, and
- providing the driver with the desired steering feel based on the determined steering device guiding force,
- wherein the friction model represents friction between a flexible element and the steering device in the steering arrangement, wherein the flexible element is configured for a relative displacement in a circumferential direction about a steering axis, which displacement is generated between an upper and a lower shaft of the steering arrangement.
A system for assisting a driver of a vehicle during operation by providing the driver with a desired steering feel in a mechanical steering arrangement, the mechanical steering arrangement comprising a steering device, at least one ground engagement member, and a mechanical connection between the steering device and the at least one ground engagement member, comprising
- means for determining a desired steering device guiding force comprising a part representing a desired friction in a steering arrangement, wherein the means for determining the desired steering device guiding force comprises at least one predetermined friction model of the desired friction in the vehicle steering arrangement, and means for providing the driver with the desired steering feel based on the determined steering device guiding force,
- wherein the friction model represents friction between a flexible element and the steering device in the steering arrangement, wherein the flexible element is configured for a relative displacement in a circumferential direction about a steering axis, which displacement is generated between an upper and a lower shaft of the steering arrangement.
