Patent number: 12233974Abstract: The present disclosure relates to a method for controlling steering of a vehicle arrangement. The method is controlling steering of the vehicle arrangement during a turning maneuver, by applying a differential wheel speed by at least one of individually controllable electric machines and reducing the operational capacity of a power steering system, when a first power utilization value, obtained by operating the individually controllable electric machines with the differential wheel speed, is equal to, or greater than a second power utilization value, obtained by operating the power steering system during the turning maneuver.Type: GrantFiled: August 24, 2020Date of Patent: February 25, 2025Assignee: Volvo Truck CorporationInventors: Leo Laine, José Vilca, Rebecka Villiamsson

Publication number: 20240208567Abstract: A steering assembly for a vehicle comprises first and second steering actuators, each configured to be actuated in accordance with at least one signal issued from a motion control system to control a steering angle of at least one steerable ground engaging member of the vehicle. The first and second steering actuators are associated with corresponding first and second nominal steering capabilities, each defining at least one limitation of at least one of the following: steering angle, steering angle rate and steering torque, for the at least one steerable ground engaging member. The motion control system is adapted to, upon detection of a malfunction associated with the first steering actuator, associate the second steering actuator with a second enhanced steering capability instead of the second nominal steering capability. The second enhanced steering capability is different from the second nominal steering capability.Type: ApplicationFiled: March 6, 2024Publication date: June 27, 2024Inventors: Leo Laine, Jan-Inge Svensson, Lionel Farres, Christian Oscarsson, Leon Henderson, Jose Vilca, Kristoffer Tagesson, Johanna Majqvist
