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 military vehicle includes a passenger capsule, a front module coupled to a front end of the passenger capsule, a rear module coupled to a rear end of the passenger capsule, a front axle coupled to the front module, a rear axle coupled to the rear module, an engine coupled by the front module, a front differential coupled to the front axle, a transaxle, and an actuator. The transaxle is coupled to the engine, the rear axle, and the front differential. The transaxle includes an internal mechanical disconnect that facilitates decoupling the transaxle from the front differential. The actuator is accessible from an exterior of the passenger capsule to engage the internal mechanical disconnect.

A vehicle chassis platform including: a frame having a front frame end, a rear frame end, a longitudinal frame axis, an upper frame surface, a bottom frame surface, a first longitudinal lateral frame surface and a second longitudinal lateral frame surface, wherein the upper frame surface is substantially flat; and two or more mechanical connection assemblies each coupled to one of the first and second longitudinal lateral surfaces, each of mechanical connection assemblies to couple a vehicle corner module (VCM) to the frame and to transfer mechanical loads between the frame and the VCM when the VCM is coupled to the frame.

Systems, apparatus and methods to implement sectional design (e.g., in quadrants) of an autonomous vehicle may include modular construction techniques to assemble an autonomous vehicle from multiple structural sections. The multiple structural sections may be configured to implement radial and bilateral symmetry. A structural section based configuration may include a power supply configuration (e.g., using rechargeable batteries) including a double-backed power supply system. The power supply system may include a kill switch disposed on a power supply (e.g., at an end of a rechargeable battery). The kill switch may be configured to disable the power supply system in the event of an emergency or after a collision, for example. The radial and bilateral symmetry may provide for bi-directional driving operations of the autonomous vehicle as the vehicle may not have a designated front end or a back end.

A method for assembling a vehicle from a set of modules for travelling a planned route, wherein the set of modules comprises at least one functional module and a plurality of drive modules. Each drive module comprises a pair of wheels, electrical motor, and an interface releasably connectable to a corresponding interface on another module, wherein each drive module is configured to operate autonomously and has an individual set of energy parameters. The method comprising obtaining route information associated with route segments of the planned route, selecting a first drive module having an individual set of energy parameters matching route information associated with a first route segment and selecting a second drive module having an individual set of energy parameters matching route information associated with a second route segment, and thereafter commanding the drive modules to connect together and with a functional module.

A military vehicle includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, and a driveline. The driveline includes an engine, an energy storage system, a front end accessory drive positioned in front of and coupled to the engine, a transmission coupled to at least one of the front axle or the rear axle, a second motor coupled to the transmission and electrically coupled to the energy storage system, and a clutch positioned between the engine and the second motor. The front end accessory drive includes an air compressor and a first motor. The first motor is electrically coupled to the energy storage system. The clutch is spring-biased into engagement with the engine and pneumatically disengaged by an air supply selectively provided thereto based on operation of the air compressor. The driveline is operable in an engine-only mode and an electric-only mode.

An electrically powered motor vehicle includes a main frame, a front axle assembly, and a rear axle assembly. The main frame includes a front frame subassembly, a floor-panel subassembly, a rear frame subassembly, and a top frame subassembly. Each of these frame subassemblies includes a lattice structure including steel box-section elements, preferably high-strength steel elements. Each of the frame subassemblies is prearranged for being pre-assembled separately and then subsequently assembled together with the other subassemblies to constitute the main frame. The structure is such as to afford high flexibility of production, and presents at the same time considerable safety characteristics, thanks to a high capacity of absorption of impact energy. In one embodiment designed for transport of goods, the motor vehicle is equipped with a transporting body having a hollow-walled body made of plastic material, filled with foamed plastic material, preferably obtained with the rotational-moulding technique.
