1. A control system for controlling one or more torque generating devices on a heavy-duty vehicle, the system comprising:
a primary sensor system with a primary sensor control unit configured to interpret an output signal of the primary sensor system, wherein the primary sensor control unit is configured to determine a first load value associated with the heavy-duty vehicle, wherein the first load value is determined based on the output signal of the primary sensor system, and
one or more tire sensor devices mounted on one or more tires of the heavy-duty vehicle, and a tire sensor control unit configured to interpret an output signal of the one or more tire sensor devices, wherein the tire sensor control unit is configured to determine a second load value associated with the heavy-duty vehicle, wherein the second load value is determined based on the output signal of the one or more tire sensor devices,
wherein the control system is arranged to base motion control of the heavy-duty vehicle on the second load value in case of malfunction in the primary sensor system and/or in the primary sensor control unit, and on the first load value otherwise.
