In one aspect of the present disclosure, a method is provided for operating a vehicle system comprising a motor, a battery, and a controller. The vehicle system is configured to provide at least one of regenerative braking wherein the motor operates to charge the battery and propulsion wherein the motor uses electrical power from the battery to propel the vehicle. The method includes, at the controller, determining an effective motor power at a motor speed and a motor torque. The effective motor power is determined based at least in part on a calculated motor power and an electrical power loss of the motor corresponding to the motor speed and the motor torque. The method further includes causing the motor to apply the motor torque to a wheel of the vehicle upon the effective motor power satisfying an operating condition of the vehicle system.

A vehicle powertrain comprising a first and second electric machines, and a transmission arranged to transmit torque from said electric machines to a driving axle, the transmission comprising: first and second input shafts arranged to be driven by the machines, respectively, a common output shaft, a first gear set comprising:
first and second input gears via which torque is transmittable from the respective input shafts, to the output shaft; a second gear set comprising:
third and fourth input gears via which torque is transmittable from the respective input shafts to the output shaft; means for disconnecting each machine from each other and from the output shaft; an intermediate shaft drivable by the first and/or the second input gear; and an auxiliary gear set having two gear ratios arranged between the intermediate and common output shafts, at least the first gear set being arranged to drive the output shaft via the intermediate shaft and the auxiliary gear set.

A dolly adapted to be coupled to a semitrailer, where the dolly comprises a first steerable axle and a second axle provided with a drive unit, and where the dolly comprises a fifth wheel and a drawbar, where the dolly further comprises a cover having a front compartment in front of the first axle, where the front compartment comprises a first radiator and where the cover comprises a first air opening adjacent the drawbar. In this way, a dolly with integral cooling is provided.

A compartment for storing an energy source in a vehicle having a protective outer structure and an inner structure. The protective outer structure is maintained in position relative to the vehicle during normal operation of the vehicle. The inner structure, which holds the energy source, is positioned in the outer structure. The inner structure is maintained in position relative to the outer structure and relative to the vehicle during normal operation of the vehicle. During an impact to the vehicle, the inner structure is configured to move independent of the outer structure.

A vehicle powertrain comprising a first and second electric machines, and a transmission arranged to transmit torque from said electric machines to a driving axle, the transmission comprising: first and second input shafts arranged to be driven by the machines, respectively, a common output shaft, a first gear set comprising:
first and second input gears via which torque is transmittable from the respective input shafts to the output shaft; a second gear set comprising:
third and fourth input gears via which torque is transmittable from the respective input shafts to the output shaft; means for disconnecting each machine from each other and from the output shaft an intermediate shaft drivable by the first and/or the second input gear; and an auxiliary gear set having two gear ratios arranged between the intermediate and common output shafts, at least the first gear set being arranged to drive the output shaft via the intermediate shaft and the auxiliary gear set.

A system and method are provided and include a light source projector with a positional actuator mounted on a subject vehicle that projects laser lines on a roadway upon which the subject vehicle is traveling. A controller receives steering angle data from a steering system of the subject vehicle, the steering angle data corresponding to a steering angle of the subject vehicle. The controller determines a turning path of the subject vehicle based on the steering angle data and controls the positional actuator to project the laser lines on the roadway to correspond to the determined turning path of the subject vehicle.

A fuel additive cartridge for use with a dimethyl-ether fuel system of a vehicle includes a reservoir for storing and dispensing a liquid fuel additive into a flow of fuel in a fill conduit during refueling. The cartridge also includes a dispenser actuated by the fuel flow to selectively dispense the liquid fuel additive from the reservoir. The fuel additive cartridge is intended to attach to a dimethyl-ether fuel system at a location between a fueling inlet connector and a storage tank to facilitate a metered mixing of liquid fuel additive from the cartridge and dimethyl-ether during the re-fueling of the storage tank.

A vehicle undercover mounting bracket for mounting an undercover body is provided. The vehicle undercover mounting bracket includes a frame-side mounting portion mounted on a side rail of a truck frame, an undercover-side mounting portion mounted on the undercover body and spaced apart from the frame-side mounting portion in a longitudinal direction of the side rail, and a connecting portion which extends in the longitudinal direction of the side rail and connects the frame-side mounting portion and the undercover-side mounting portion.

A twin-wheel drive module for driving two vehicle wheels which are disposed spaced axially from one another and rotatable around two axes of rotation aligned with one another. For driving each vehicle wheel, provision is made for a traction motor having a motor shaft disposed in parallel to the axes of rotation, a transmission having an input shaft which is connected to the motor shaft of the traction motor and an output shaft in alignment with the axes of rotation, and a second transmission. The second transmission has an input shaft, which is connected to the output shaft of the first transmission, and an output shaft which rotates around a common axis of rotation with the input shaft configured to receive the vehicle wheel.

A fluid system for a vehicle is provided. The fluid system is configured to couple to a chassis of the vehicle. A frame assembly of the fluid system is configured to couple with the chassis directly or with another component that is coupled, directly or indirectly, with the chassis. A cowling of the fluid system can enclose a fuel pressure vessel and an auxiliary fluid vessel. The auxiliary fluid vessel is configured to be placed in fluid communication with the component powered or operated by the fluid therein.
