Abstract
A control unit for controlling at least one MSD on a heavy-duty vehicle is provided. The control unit is arranged to determine a limiting operating point of the MSD associated with a performance limit of the MSD, determine a preferred operating point of the MSD indicative of an operating point of the MSD associated with an improvement in a secondary objective function value compared to the limiting operating point, and transmit a capability message to a VMM function comprising the limiting operating point of the MSD and the preferred operating point of the MSD.
Claims16
A motion support device (“MSD”) control unit for controlling at least one MSD on a heavy-duty vehicle, wherein the control unit is arranged to:
- determine a limiting operating point of the MSD associated with a performance limit of the MSD,
- determine a preferred operating point or range of operating points of the MSD indicative of an operating point or range of operating points of the MSD associated with an improvement in a secondary objective function value compared to the limiting operating point, and transmit a capability message to a vehicle motion management (“VMM”) function comprising the limiting operating point of the MSD and the preferred operating point of the MSD.
A vehicle unit computer (“VUC”) arranged for vehicle motion management (“VMM”) of a heavy-duty vehicle, wherein the VUC is arranged to:
- obtain a motion request comprising an acceleration profile and/or a curvature profile from a traffic situation management (“TSM”) function,
- perform vehicle state and/or motion estimation to estimate a current and/or future state of the heavy-duty vehicle,
- perform force generation to determine a set of global forces to cause the vehicle to move according to the motion request, and
- coordinate a plurality of motion support devices (“MSD”) by an MSD coordination module to generate a set of MSD actuator requests,
- wherein the MSD coordination module is arranged to receive at least one capability message from an MSD control unit, where the capability message comprises a limiting operating point of the MSD and a preferred operating point of the MSD,
- where the MSD coordination module is arranged to coordinate the plurality of MSDs based on the received at least one capability message.
A computer implemented method performed in a motion support device (“MSD”) control unit for controlling at least one MSD on a heavy-duty vehicle, the method comprising:
- determining a limiting operating point of the MSD associated with a performance limit of the MSD,
- determining a preferred operating point of the MSD indicative of an operating point of the MSD associated with an improvement in a secondary objective function value compared to the limiting operating point, and
- transmitting a capability message to a vehicle motion management (“VMM”) function comprising the limiting operating point of the MSD and the preferred operating point of the MSD.
