  • Patent number: 9849910
    Abstract: A method is provided for determining a maximum speed limit for a reversing vehicle combination that includes a towing vehicle and at least one towed trailer. The method includes determining a maneuver that is to be performed by the vehicle combination, simulating the complete maneuver in advance by using a control algorithm and a state space model, thereby obtaining the steering behavior of the vehicle combination during the maneuver, and calculating the maximum speed limit for the vehicle combination during the maneuver by using at least one predefined limiting condition. A maximum speed limit for a reverse assistance function can be estimated in advance, which allows for a faster and more efficient reversing of the vehicle combination, and at the same time allows for an improved comfort for the driver.

  • Patent number: 9598089
    Abstract: An arrangement for improving stability of a vehicle combination includes a towing vehicle and at least one towed vehicle, where the at least one towed vehicle includes an actively steered axle and/or individual brake on at least one axle, where the towing vehicle and the at least one towed vehicle each includes a lateral acceleration determining arrangement.

  • Patent number: 9573589
    Abstract: An arrangement for improving stability of a vehicle combination including a towing vehicle and at least one towed vehicle, where the at least one towed vehicle includes at least one actively steered axle and/or individual brake on at least one axle, where the towing vehicle and the at least one towed vehicle each includes an arrangement for determining yaw rate for determining the yaw rate of the vehicle and the at least one towed vehicle, where the arrangement further includes a vehicle combination model adapted for determining a desired delay value between the yaw rate of the towing vehicle and the yaw rate of the at least one towed vehicle, where the arrangement is adapted to stabilize the at least one towed vehicle by using the determined yaw rate of the towing vehicle and the desired delay value for the at least one towed vehicle to establish a desired yaw rate for the at least one towed vehicle, and to control the steered axle and/or the individual brake of the at least one towed vehicle such that the d

  • Publication number: 20150298738
    Abstract: A method is provided for determining a maximum speed limit for a reversing vehicle combination that includes a towing vehicle and at least one towed trailer. The method includes determining a manoeuvre that is to be performed by the vehicle combination, simulating the complete manoeuvre in advance by using a control algorithm and a state space model, thereby obtaining the steering behaviour of the vehicle combination during the manoeuvre, and calculating the maximum speed limit for the vehicle combination during the manoeuvre by using at least one predefined limiting condition. A maximum speed limit for a reverse assistance function can be estimated in advance, which allows for a faster and more efficient reversing of the vehicle combination, and at the same time allows for an improved comfort for the driver.

  • Publication number: 20150291179
    Abstract: A method is provided for estimating the effective wheelbase length of a trailer in a vehicle combination including a towing vehicle and at least one towed trailer. The method includes driving the vehicle combination forwards, determining the speed of the vehicle combination, determining the steering angle of the towing vehicle, determining the steering angle of each towed trailer, determining the yaw rate of the towing vehicle and the yaw rate of the towed trailer or determining the articulation angle for each towed trailer, and using the determined values to calculate a value for the effective wheelbase for each towed trailer. An arrangement for estimating the effective wheelbase length of a trailer in a vehicle combination is also disclosed.
