A refuse vehicle includes a lift assembly configured to engage and lift a refuse receptacle, an electrical energy system configured to store power and supply power to the refuse vehicle, and a controller configured to determine an amount of power required to move the refuse vehicle to a charging location, measure one or more electrical attributes of the refuse vehicle to determine an amount of length of time the refuse vehicle can operate based on a remaining power of the electrical energy system, and limit operations of one or more components of the refuse vehicle based on a comparison of the amount of power required to move the refuse vehicle to the charging location and the amount of length of time the refuse vehicle can operate.

A multipurpose vehicle system with interchangeable operational components and power supplies is operational in multiple operational modes. The operational modes include: a personal transport vehicle mode, a service vehicle mode, and a commercial vehicle mode. The vehicle system has a dimensionally adjustable chassis module. The chassis module has the capacity to detachably attach to multiple exterior, interior, motor, and transmission components. The chassis module supports a cabin module and a rear module that enables formation of different iterations of vehicles. The vehicle system provides multiple different and interchangeable power supplies, like a rechargeable battery and a hydrogen tank. The power supplies are interchangeable. The used components can be recycled and interchanged with new components. The vehicle system also comprises at least one autonomous trailer that comprises a receiver in communication with a transmitter in the chassis module, allowing the autonomous trailer to be remotely towed by the chassis module.

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.

An electric machine drive arrangement for a heavy-duty vehicle. The electric machine drive arrangement comprises a motor drive system inverter with an alternating current side for interfacing with an electric machine. The electric machine drive arrangement comprises a brake arrangement comprising a braking resistor circuit connectable to a control circuit. The electric machine drive arrangement comprises a rectifier arrangement connected in parallel between the brake arrangement and the motor drive system inverter on the alternating current side of the motor drive system inverter.

A method for determining aging of a fuel cell system for a vehicle, comprising identifying a future interval in terms of time or distance during which the fuel cell system is expected to operate at stationary operating conditions, obtaining measurement values pertaining to at least one fuel cell parameter indicative of degradation of the fuel cell system during the identified interval, and determining an aging state of the fuel cell system using the measurement values.

A driverless transport vehicle, a conveying system, and a method for transporting piece goods. The driverless transport vehicle overcomes a climbing section equipped with a primary side of an energy transmission device. The driverless transport vehicle, which can be moved individually and autonomously on a conveying plane, has a secondary side for energy pick-up in order, assisted by the energy pick-up, to overcome a height difference of the climbing section and/or a transition between the conveying plane and the climbing section. The formation of a connection between the primary side and the secondary side and the overcoming of the climbing section and of the transition between the conveying plane and the climbing section take place at a throughput speed without a slowing-down.

The disclosure relates to a method for actuating an electrical drive of a trailer vehicle with a towing vehicle. According to an embodiment, the method include the steps of: determining a current mass of the towing vehicle; determining a current drive force of the towing vehicle; determining an acceleration demand in dependence upon the current mass and the current drive force; and, actuating the electric drive via an actuating signal in dependence upon the acceleration demand. The disclosure also relates to a control device for executing the method, a towing vehicle, a trailer vehicle and a semi-trailer truck.

Various systems are provided for charging electric vehicles. The systems may include a power transformation module in electrical communication with a power supply, any number of charge nodes in electrical communication with the power transformation module via one or more power distribution lines, and any number of charge transfer devices, each in electrical communication with a power system of an electric vehicle. A charge node of a charge pad may be connected to a contact pad of a charge transfer device to transfer power from the charge node, through the charge transfer device, to the vehicle power system to thereby charge the vehicle.

Devices, systems, and methods for redundant braking systems and architectures are described. An example method for controlling a vehicle includes receiving, by a braking system, a first set of commands generated by a primary brake controller and a primary vehicle control unit (VCU) comprising multiple processors, receiving a second set of commands generated by the primary VCU and a secondary brake controller, receiving a third set of commands generated by a secondary VCU and the primary brake controller, receiving a fourth set of commands generated by the secondary VCU and the secondary brake controller, and selecting, based on an arbitration logic, exactly one of the first, second, third, and fourth sets of commands to operate the braking system, wherein the primary VCU and the secondary VCU are configured in a master/slave architecture.
