A braking arrangement for decelerating a heavy duty vehicle, the arrangement including a control unit, at least one electric machine arranged for regenerative braking, an electrical energy absorption device, an eddy current braking device, and a power distribution network arranged to connect the electric machine to the energy absorption device and to the eddy current braking device, wherein the control unit is configured to distribute regenerated electrical power from the electric machine between the energy absorption device and the eddy current braking device by the power distribution network in dependence of a target deceleration value of the heavy duty vehicle.

Braking arrangement for heavy duty vehicles

A wheel brake arrangement for a vehicle, the wheel brake arrangement comprising an eddy current wheel brake configured to receive electric power from a source of electric power of the vehicle during braking, and a transmission arrangement comprising a first shaft connected to the eddy current wheel brake and a second shaft connectable to a wheel of the vehicle, wherein the transmission arrangement comprises a ratio varying arrangement, the ratio varying arrangement being configured to, for any rotational speed below a predetermined threshold speed of the second shaft during braking, control a rotational speed of the first shaft to be maintained within a predetermined rotational speed range.

Wheel brake arrangement for a vehicle

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.

Electrical wheel module for acceleration and braking of a heavy-duty vehicle

A single axle dolly vehicle unit for a heavy duty vehicle combination, the dolly vehicle unit comprising an electrical energy source arranged to power at least one electric machine configured to drive left and right wheels of the single axle, the dolly vehicle unit further comprising a drawbar and a fifth wheel connection for mating with first and second trailer units, respectively, wherein the fifth wheel connection is arranged to be adjusted in height over ground by a variable height suspension system, the dolly vehicle unit further comprising a control unit arranged to control the variable height suspension system.

Self-powered single axle dolly vehicle unit with auto-coupling ability

A wheel end computer, WEC, () for hosting and executing one or more motion support device abstraction modules (MSDA,) configured to monitor and/or to control operations of one or more respective motion support devices, MSDs, () on a heavy duty vehicle, where an MSDA provides a control and/or a monitoring interface between an external vehicle unit computer (VUC,), and a respective MSDs operational functionality, wherein the WEC () is arranged to identify a matching MSDA for each MSD in a set of MSDs, such that each MSD connected to the WEC is matched to a respective MSDA, and wherein the WEC () is arranged to receive a monitor and/or a control command from the VUC () for monitoring and/or controlling an MSD connected to the WEC, and to control the MSD via the respective matching MSDA.
