A modular auxiliary power module is described for a modular autonomous bot apparatus that transports an item being shipped. The modular auxiliary power module includes a base adapter platform, a cargo door, an auxiliary power source, and an output power outlet disposed on the base adapter platform as part of a modular component electronics interface. A top side of the base adapter platform has a cargo support area configured to support the item being shipped. Interlocking alignment interfaces (such as channels or latches) are on the top and bottom of the platform. The cargo door is movably attached to and extending from an edge of the base adapter platform, and the output power outlet is coupled to the auxiliary power source and provides access to power for other components of the modular autonomous bot apparatus from the auxiliary power source.

Methods perform one or more dispatched medical logistics operations using a modular autonomous bot apparatus assembly and a dispatch server where the operations are related to a diagnosis kit for treating a patient. The MAM of the bot receives a dispatch command, verifies compatibility of the bot assembly with the dispatched operation(s), receives a diagnosis kit in the CSS, has the MAM autonomously causing the MB to move to a destination location while notifying the authorized delivery recipient for the diagnosis kit of the approaching delivery. With appropriate authentication input received, the MAM coordinates with the CSS to provide access to the kit, monitor unloading of the kit, provide instructional information on use of the kit, and autonomously cause the MB to return to the original location with a return item related to the diagnosis kit with notification to personnel at the medical entity about the return item.

A mechanically suspended vehicle has a travel measurement device (9), a control unit (10) and an algorithm stored in the control unit (10). The algorithm performs a method for determining an axle load. In a first test routine a level signal of a travel measurement device is acquired and evaluated, wherein, in a loading operation of the vehicle, a loading curve (F_i) is determined, and, in an unloading operation of the vehicle, an unloading curve (F_u) is determined. The values of the two curves are used to calculate an averaged load-travel characteristic curve (F_m) to be stored in the control unit. After each start of the vehicle, an axle load determination routine is repeated cyclically, and axle load values are continuously determined with the averaged load-travel characteristic curve (F_m). An axle load average value is calculated from the axle load values and displayed as the current axle load value.

A spring assembly for a vehicle bogie suspension arrangement. The spring assembly includes a set of washers moulded into an elastomer body. The spring assembly has an axial extension in an axial direction and the washers are arranged relative to each other in the axial direction. At least one of the washers is a spring washer including a spring washer body and at least two spring tongues. Each spring tongue has a spring base connected to the spring washer body and a spring tip distal to the spring base. At least a portion of the spring tongue is located at a non-zero distance from the spring base in the axial direction.

Techniques are described for compensating for movements of sensors. A method includes receiving two sets of sensor data from two sets of sensors, where a first set of sensors are located on a roof of a cab of a semi-trailer truck and a second set of sensor data are located on a hood of the semi-trailer truck. The method also receives from a height sensor a measured value indicative of a height of the rear of a rear portion of the cab of the semi-trailer truck relative to a chassis of the semi-trailer truck, determines two correction values, one for each of the two sets of sensor data, and compensates for the movement of the two sets of sensors by generating two sets of compensated sensor data. The two sets of compensated sensor data are generated by adjusting the two sets of sensor data based on the two correction values.

An adjustable anti-roll bar arrangement for a vehicle, comprising a bracket configured to be mounted in a fixed relationship to a chassis or a an axle of the vehicle, a linear actuator connected to the bracket, a guided element, the linear actuator being configured to drive the guided element along a first geometrical axis, a supporting shaft mounted to the bracket and defining a second geometrical axis which has a different extension compared to the first geometrical axis, an anti-roll bar, and a stabilizer stay having a first end connected to the anti-roll bar, and a second end movably connected to and supported by the supporting shaft, the second end being also connected to the guided element such that when the linear actuator drives the guided element along the first geometrical axis, the second end follows the motion along the second geometrical axis. The invention also relates to a vehicle comprising such an arrangement.

Methods and systems are provided for a medium duty vehicle. In one example, the medium duty vehicle has a storage compartment with a first suspension system and a cab with a separate, second suspensions system. The cab may be separated from the storage compartment by a physical barrier and may include a rearward extension overlapping with the storage compartment.

A utility vehicle includes a wheel, a vehicle body frame supported by the wheel, a suspension device connecting the wheel to the vehicle body frame, and an acceleration sensor mounted on the suspension device. The suspension device includes: a below-shock absorber member including an arm swingably connecting the wheel to the vehicle body frame; and a shock absorber connecting the below-shock absorber member to the vehicle body frame. The acceleration sensor is mounted on the arm.

Aspects of the disclosure relate to an anti-dive bar system that includes a first bar with a first floating end and a first fixed end mechanically coupled to a first axle. The anti-dive bar system further includes a second bar with a second floating end and a second fixed end mechanically coupled to a second axle. The anti-dive bar system further includes a coupler with a sleeve and a locking member. The sleeve is configured to receive at least a portion of the first bar. The locking member is moveable between a retracted position in which the first floating end of the first bar is moveable relative to the sleeve and the second floating end of the second bar and an extended position in which the first floating end of the first bar is fixed relative to the sleeve and the second floating end of the second bar.

A self contained battery and slide frame houses a pair of trailer axles and an electrical vehicle storage battery secured by parallel slide frame rails adapted for attachment to an underside of a standard tractor trailer (Class 8) trailer frame. The slide frame attaches to an underside of a trailer using perforated frame beams used to vary a position of the wheel/axle assemblies relative to the trailer body and payload. The slide frame rails provide self contained support for a storage battery, e-axle, control electronics and connecting wires for charging and running a vehicle load from the storage battery. Vehicle loads powered by the storage battery include transport refrigeration units (TRUs) and electrical vehicle (EV) tractors.
