摘要： A method and an arrangement for assisting a driver of a vehicle during operation by providing the driver with a desired steering feel, wherein the vehicle includes a steering arrangement including an input shaft connected to a manually operated steering device, an output shaft connected to at least one pair of ground engaging members and a mechanical interconnection connecting the output shaft and the input shaft. The method involves detecting a first steering angle for the output shaft, which first steering angle indicates the position of the ground engaging members; detecting a second steering angle for the input shaft, which second steering angle indicates the position of the steering device; comparing the first and second steering angles and determining a current state of the steering arrangement; and controlling a first actuator connected to the output shaft and a second actuator connected to the input shaft in response to the detected first and second steering angles, in order to achieve a desired state of the steering arrangement; and applying a torque to the steering device proportional to the angular difference between the output shaft and the input shaft using a resilient portion in the mechanical interconnection, in order to provide the driver with a desired steering feel.

摘要： A wheel suspension arrangement is provided for a vehicle having a longitudinal direction, a transverse direction and a vertical direction. The wheel suspension arrangement includes a wheel holder for supporting a vehicle wheel. A first vertical end region of the wheel holder is pivotally attached to a vehicle support structure by a rigid control arm and a second vertical end region of the wheel holder is attached to the vehicle support structure by a leaf spring. A longitudinal direction of the leaf spring is arranged substantially in the transverse direction of the vehicle. The leaf spring is pivotally attached to the vehicle support structure at a transverse centre region of the vehicle, and a centre of the leaf spring in the transverse direction is located vertically offset from a pivotal attachment location of the leaf spring. The pivotal attachment location of the leaf spring is vertically offset towards the side of the rigid control arm.

摘要： A vehicle suspension leaf spring assembly is arranged to be mounted in the longitudinal direction of the vehicle, on both sides thereof, the leaf spring assembly having a first end, which is arranged for pivotal connection to a first bracket on the vehicle; and a second end, which is arranged for connection to a spring shackle on the vehicle, wherein the leaf spring assembly is arranged to be connected to an axle extending transversely of the leaf spring assembly at a position intermediate the first and second ends of the leaf spring assembly. The leaf spring assembly includes an upper spring arrangement comprising two individual upper leaf springs arranged side-by-side with a predetermined spacing and extending between the first and second ends, and at least one lower spring arrangement arranged below the upper leaf springs.
