Abstract

A vehicle chassis having substantially all of the mechanical, electrical, and structural componentry necessary for a fully functional vehicle includes at least an energy conversion system, a steering system, and a braking system. The chassis is configured for matability with a variety of different types or styles of vehicle bodies. Various prior art mechanical control linkages between a driver and controlled systems are replaced with non-mechanical control signal transmission components. Fuel cell technology is also implemented. The chassis may also include an electrical connector operably connected to the fuel cell and configured to transmit electrical energy from the fuel cell to an offboard system that consumes electrical energy. Chassis may be stacked and/or have interconnected fuel cells to increase electrical energy output.

Claims (11)

1. A vehicle chassis comprising:

a structural frame; a steering system mounted with respect to the structural frame; a by-wire braking system mounted with respect to the structural frame; an energy conversion system including a fuel cell configured to generate electrical energy, controllable by wire, and mounted with respect to the structural frame; a body-attachment interface supported with respect to the frame and having body connection components including at least one load-bearing body-retention coupling; and an electrical connector operably connected to the fuel cell and and configured to transmit electrical energy from the fuel cell to an off-board system that consumes electrical energy;

wherein the body connection components further include at least one control signal receiver, and wherein the braking system and energy conversion system are both operably connected to said at least one control signal receiver; and

wherein said steering system is controllable by wire, and the steering system is operably connected to said at least one control signal receiver.

2. A vehicle comprising:

a chassis having

a structural frame; a by-wire steering system mounted with respect to the structural frame; a by-wire braking system mounted with respect to the structural frame; an energy conversion system including a fuel cell configured to generate electrical energy, controllable by wire, and mounted with respect to the structural frame; a body-attachment interface supported with respect to the structural frame and having body connection components including at least one load-bearing body-retention coupling; and an electrical power connector operably connected to the fuel cell and configured to transmit electrical energy from the fuel cell; and

a body mounted to the chassis at the at least one load-bearing body retention coupling, and having a first electrical connector operably connected to the electrical power connector and a second electrical connector operably connected to the first electrical connector and configured to transmit electrical energy to an off-board system that consumes electrical energy.

3. The vehicle of claim 2 , wherein the chassis further includes an energy storage system configured to store hydrogen and operably connected to the energy conversion system.

4. The vehicle of claim 2 , wherein the body connection components further include at least one control signal receiver, and wherein the steering system, braking system, and energy conversion system are each operably connected to the control signal receiver.

5. The vehicle chassis of claim 2 , further comprising a plurality of wheels operably connected to the steering system, energy conversion system and braking system.
