Abstract: A control unit for managing the motion of a heavy-duty vehicle via real-time kinematic positioning is disclosed. The control unit comprises a vehicle state interface designed to retrieve state information from vehicle state sensors, including kinematic parameters and information about the availability of RTK correction data. The nominal operational design domains and corresponding RTK-enhanced ODDs are defined, wherein each nominal ODD maintains enhanced safety margins when contrasted with its RTK-enhanced counterpart. The control unit's functionality includes the selection of an active ODD based on availability of RTK correction data, selecting an RTK-enhanced ODD when such data is available, and selecting a nominal ODD when absent. The control unit subsequently directs the vehicle's motion using the kinematic parameters in alignment with the active ODD.

Abstract: A computer implemented method for determining a road friction condition associated with at least one wheel on a heavy-duty vehicle includes transmitting a radar signal by at least one polarimetric radar transceiver towards a surface supporting the vehicle, and receiving backscatter from the transmitted radar signal, where the radar signal comprises a first polarization component and a second polarization component different from the first polarization component, processing the received backscatter by a processing device to determine a friction parameter related to the road friction condition of the surface, monitoring the friction parameter over time to detect change in the friction parameter, and in case change in the friction parameter is detected, triggering friction estimation by a secondary physical friction estimation system.

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.

Abstract: A sensor device comprises an advanced antenna array radar transceiver configured to measure motion of the sensor device relative to an external surface in a reference frame of the sensor device and provide corresponding radar data, and an inertial measurement unit, IMU, configured to measure motion of the sensor device in a reference frame of the sensor device and provide corresponding IMU data. The advanced antenna array radar transceiver and the IMU are fixedly mounted relative each other. Processing circuitry is configured to determine an orientation of the sensor device relative an inertial reference frame (e.g., in terms of one or more Euler angle(s)) based on joint processing of the radar data and the IMU data.
