    摘要： The invention relates to a method for controlling wheel slip of a vehicle (100), wherein the vehicle (100) comprises at least a first and a second motion support device, MSD (116, 114), for providing torque to a common wheel (102) of the vehicle (100). The method comprises receiving a wheel torque request. Based on the received wheel torque request, the method further comprises controlling the first MSD (116) to provide torque to the wheel (102) in a first mode of operation, and controlling the second MSD (114) to provide torque to the wheel (102) 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.

    摘要： The present disclosure relates to a vehicle motion management system (200) as well as an actuator control system (300) of a vehicle. The vehicle motion management system (200) and actuator control system (300) are arranged to control operation of at least one actuator (104) configured to apply a torque to at least one wheel of the vehicle. The vehicle motion management system (200) is configured to transmit a control signal (550) to the actuator control system (300), wherein the actuator control system (300) is configured to, based on the control signal (550), generate an operating torque to be executed subject to the torque limit and the desired wheel speed.

    摘要： A control unit (130, 140) for controlling a heavy duty vehicle (100),
    wherein the control unit is arranged to obtain input data indicative of a desired wheel force (Fx, Fy) to be generated by at least one wheel (210) of the vehicle (100), and
    to translate the input data into a respective equivalent wheel speed or wheel slip to be maintained by the wheel (210) to generate the desired wheel force (Fx, Fy) based on an inverse tyre model (f -1 ) for the wheel (210),
    wherein the control unit (130, 140) is arranged to obtain the inverse tyre model in dependence of a current operating condition of the wheel (210), and
    wherein the control unit (130, 140) is arranged to control the heavy duty vehicle (100) based on the equivalent wheel speed or wheel slip.

    摘要： A control unit (130, 140, 300) for controlling a heavy duty vehicle (100),
    wherein the control unit is arranged to obtain an acceleration profile (a req ) and a curvature profile (c req ) indicative of a desired maneuver by the vehicle (100),
    the control unit (130, 140, 300) comprising a force generation module (310) configured to determine a set of global vehicle forces and moments required to execute the desired maneuver,
    the control unit (130, 140, 300) further comprising a motion support device, MSD, coordination module (320) arranged to coordinate one or more MSDs to collectively provide the global vehicle forces and moments by generating one or more respective wheel forces, and
    an inverse tyre model (330) configured to map the one or more wheel forces into equivalent wheel slips (λ),
    wherein the control unit (130, 140, 300) is arranged to request the wheel slips (λ) from the MSDs.
