A system is disclosed having a primary vehicle and a secondary vehicle that is carried by the primary vehicle when not in use. The system further includes at least one of an immobilizing device to immobilize the primary vehicle if the secondary vehicle is removed from the primary vehicle, a data storage device for storing information regarding usage of the primary and secondary vehicles, a user interface device for displaying information regarding usage of the primary and secondary vehicles, and a user prompt for providing information regarding potential opportunities for use of the secondary vehicle to encourage usage of the secondary vehicle and lower CO2 emissions.

Join two automobiles safely, securely and strongly with weatherproof joint, temporarily on need basis to become one automobile, in such a manner that the interior space of joined automobiles becomes contiguous and weather protected to allow the occupants to move within the bigger contiguous, enclosed weather protected space without having to step outside any of the joined automobiles. Such joined automobiles shall combine their propulsion power, increase their driving range and allow bigger or heavier payload to be carried that cannot be carried by any of the unjoined automobile alone.

A stackable mobile platform vehicle with a body with attached tires and wheels with a load bearing strength of at least 2500 pounds. In some instances the platform vehicle is powered by an electrical motor coupled to a generator which is powered by an internal combustion engine. A large flat load bearing deck on top of the vehicle is sufficient to support the weight of at least one additional stackable mobile platform vehicle. In some instances electricity produced by the generator can by exported from the mobile vehicle platform for use external to the mobile vehicle platform.

A towable road motor vehicle including: at least three wheels, capable of driving the motor vehicle on a level road, distributed between two front and rear wheel trains of the motor vehicle; a chassis, including an articulation device, interposed between front and rear portions of the chassis and enabling the front portion to pivot, relative to the rear portion, to modify an articulation angle of the vehicle; front and rear hitches, respectively positioned at the front and rear of the motor vehicle, and a steering device, capable of modifying the steering angle of each wheel of the front train in response to a command by a driver of the vehicle, the steering device adapted to be actuated independently of the articulation device.

A vehicle includes a first vehicle part including a first running wheel rotatable about a first axis of rotation and a second vehicle part including a second running wheel rotatable about a second axis of rotation. The first and second running wheels have the same running-wheel diameter. A first and second bearing means for rotatably mounting the first and second running wheels are interconnected by means of a joint mechanism so that the orientation of the first and second axes of rotation relative to each other can be varied. By means of the joint mechanism, the vehicle can be transferred from a first driving configuration to a second driving configuration and from the second driving configuration to the first driving configuration while the vehicle is in motion. The conversion between the first and second driving configurations takes place automatically as a function of a driving speed of the vehicle.

A material vehicle, a traction apparatus and system, a method for controlling the bidirectional traveling of a material vehicle, and a storage medium. A material vehicle (10) comprises a vehicle body (101), an unlocking assembly (102), a plurality of front universal wheels (103) and a plurality of rear universal wheels (104), wherein the plurality of front universal wheels (103) and the plurality of rear universal wheels (104) are all in a locked state; the vehicle body (101) is used for placing a target article; the unlocking assembly (102) is used for releasing the plurality of front universal wheels (103) from the locked state when same are in a horizontal rotation direction, and controlling the material vehicle (10) to travel in a first direction by means of the plurality of front universal wheels (103); and the unlocking assembly (102) is further used for releasing the plurality of rear universal wheels (104) from the locked state when same are in the horizontal rotation direction, and controlling the material vehicle (10) to travel in a second direction by means of the plurality of rear universal wheels (104), the first direction and the second direction being opposite to each other. By means of the unlocking assembly, the plurality of front universal wheels or the plurality of rear universal wheels can be released from the locked state thereof, such that the material vehicle can change the positions of driving wheels, and bidirectional traveling can be realized without needing to turn the material vehicle around.

A versatile, modular, and stackable four-wheeled mobile platform vehicle includes a chassis having a substantially flat deck and an in-built compartment for housing battery module(s). The vehicle includes a steering assembly with a steering column configured to be selectively used in a first configuration, a second configuration, or a third configuration. The vehicle further comprises a relatively flat suspension system, and attachment provisions provided on and around the chassis for removably attaching one or more attachments to transform the vehicle into one or more useful vehicle types. The chassis allows mounting of seat(s) in multiple seating configurations. Further, each of the four wheels is motor-controlled, and is coupled to the chassis to support the chassis for rolling on a surface using a pair of control arms.
