Abstract: A method for controlling motion of a heavy-duty vehicle includes estimating a current vehicle state comprising at least velocity and acceleration, wherein the estimated current state is associated with a current state uncertainty, estimating a future vehicle state based on the current vehicle state, and on a predictive motion model of the vehicle, wherein the future vehicle state is associated with a future vehicle state uncertainty, defining a vehicle control envelope representing an operational limit of the vehicle, wherein the vehicle control envelope defines a range of vehicle states, comparing the estimated future vehicle state, and the associated future vehicle state uncertainty, to the vehicle control envelope, and, if a probability that the future vehicle state breaches the control envelope is above a configured threshold value, limiting a motion capability of the vehicle.

Abstract: A wheel module arranged to generate torque to accelerate and to decelerate a heavy-duty vehicle. The wheel module comprises at least one electric machine arranged for regenerative braking, an eddy current braking device, and an electronic control unit, ECU. The wheel module further comprises a communications port arranged for communication with an external control unit and a power distribution network arranged to connect the electric machine to the eddy current braking device and to a power port arranged to input and to output electrical power to and from the wheel module. The ECU is arranged to obtain configuration data via the communications port indicative of a maximum output power of the power port, and to control the power distribution network to maintain the output power of the power port below the maximum output power by distributing power from the at least one electric machine between the eddy current braking device and the power port.
