Abstract:
1. A method for assisting a driver of a vehicle during operation by providing the driver with a desired steering feel, wherein the vehicle comprises a steering arrangement comprising a manually operated steering device, at least one pair of ground engaging members and a mechanical interconnection between the steering device and the ground engaging members, comprising detecting a steering angle in a position at a ground engaging member side of an elastic steering force transmitting element in the steering arrangement, determining a desired steering device guiding force based on the detected, steering angle, determining a current steering torque in the steering arrangement via the elastic steering force transmitting element, determining the desired guiding force by means of at least one steering device guiding force operational model using the detected steering angle as an input, and providing the driver with the desired steering feel based on a difference between the determined desired steering device guiding force and the determined current torque in the steering arrangement, further comprising determining the current torque in the steering arrangement by detecting a relative angular movement of the elastic steering force transmitting element: and further comprising detecting a relative angular movement of the elastic steering force transmitting element by means of a first angular sensor arranged at an upper end of the elastic steering force transmitting element and a second angular sensor arranged at a lower end of the elastic steering force transmitting element.
