Abstract: A comprises a vehicle control unit, VCU, and a control module, CM, configured to control the torque actuators. The VCU is configured to send to the CM a parameter request and a desired recuperation power or a desired parameter split ratio. If the CM determines that these are conflicting targets, then based on one or more predefined criteria, the CM will apply a parameter value and allocate a recuperation power or a parameter split ratio such that the applied parameter value is different from the requested one and/or the allocated recuperation power or parameter split ratio is different from the desired one. A method of controlling a wheel is also disclosed.

Abstract: A vehicle motion management (VMM) system for a heavy-duty vehicle, configured to obtain a desired wheel force value of a wheel of the vehicle; determine a torque limit for a first motion support device (MSD) associated with the wheel based on the desired wheel force value; determine a tire model based on a relationship between wheel force and wheel speed of the wheel; determine a desired wheel speed for the first MSD based on the tire model; and determine a torque fill request for a second MSD of the vehicle based on the desired wheel force and on a torque capability of the first MSD. The VMM system determines the torque fill request for the second MSD in dependence of the torque limit for the first MSD in case the operating torque of the first MSD is limited by the torque limit, and to determine the torque fill request for the second MSD in dependence of an applied torque status signal in case the operating torque of the first MSD is not limited by the torque limit.

Abstract: A system and to a method executed in a vehicle control unit for controlling wheel slip of a vehicle, wherein the vehicle comprises at least two wheels driven by at least primary actuator via an open differential. The primary actuator is controlled to rotate at a speed resulting in a slip λem of the primary actuator. A signed wheel slip limit λlim is determined by adding a configurable value to the slip λem of the primary actuator, such that λlim>λem. The at least two wheels are controlled to rotate at wheel speeds resulting in respective wheel slips λl, λr below the signed wheel slip limit λlim, wherein each one of λl, λr and λem are signed numerical values.

Abstract: A method for controlling wheel slip of a vehicle. The vehicle comprises at least a first and a second motion support device, MSD, for providing torque to a common wheel of the vehicle. The method comprises receiving a wheel torque request. Based on the received wheel torque request, the method further comprises controlling the first MSD to provide torque to the wheel in a first mode of operation, and controlling the second MSD to provide torque to the wheel in a second mode of operation which is different from the first mode of operation. The controlling of the first MSD and the controlling of the second MSD are, at least temporarily, performed simultaneously.

IPC: B60W30/18
Abstract: The invention relates to a control unit for controlling torque applied to a vehicle wheel provided with a tyre, wherein the control unit comprises or is operatively connected to a data storage, which data storage has a stored tyre model for the tyre, wherein, in the tyre model, longitudinal tyre force is represented as at least a function of longitudinal wheel slip, longitudinal wheel slip being dependent on rotational speed of the wheel and velocity of the vehicle. The control unit is configured to correct said function based on a tyre parameter input and to convert a wheel torque request to a wheel rotational speed request based on the corrected function, and to send the wheel rotational speed request to an actuator for providing a rotational speed of the wheel corresponding to said wheel rotational speed request. The invention also relates to a method and to a kit.
