An arrangement for improving manoeuvrability of a vehicle combination that includes a first vehicle unit, a second vehicle unit and a third vehicle unit interconnected by articulated joints, where the vehicle combination includes two driven axles and where each driven axle can be controlled independently, an arrangement for determining the articulation angel between the vehicle units, an arrangement for determining a steering wheel angle of the vehicle combination, an arrangement for determining the speed of the vehicle combination, an arrangement for determining the yaw rate of the vehicle units, and an arrangement for determining a delay value between the steering wheels of the vehicle combination and at least one articulated joint, where the arrangement is adapted to control a desired articulation angle of the articulated joints by coordinating the force ratio between the two driven axles by using the determined yaw rate of the vehicle units and the determined delay value.
Arrangement for improving manoeuvrability of a vehicle combination comprising a first vehicle unit, a second vehicle unit and a third vehicle unit interconnected by articulated joints, where the vehicle combination further comprises a distributed propulsion system, in which the vehicle combination comprises a first driven axle and a second driven axle and in which the first and the second driven axles can be controlled independently, means for determining the articulation angle between the vehicle units, means for determining a steering wheel angle of the vehicle combination, means for determining the speed of the vehicle combination, means for determining the yaw rate of the vehicle units, and means for determining a delay value between the steering wheels of the vehicle combination and at least one of the articulated joints, wherein the arrangement is adapted to control a desired articulation angle of the first and the second articulated joints by coordinating the force ratio between the first driven axle and the second driven axle by using the determined yaw rate or articulation angle of the vehicle units and the determined delay value.
A method for improving the manoeuvrability of a vehicle combination comprising a first vehicle unit, a second vehicle unit and a third vehicle unit, where the vehicle combination comprises a first driven axle and a second driven axle, where the vehicle units are interconnected by articulated joints, comprising the following steps:
