1. A vehicle chassis comprising:
- a structural frame;
vehicular systems mounted with respect to the structural frame, the vehicular systems including a suspension system, a steering system, a braking system, an energy conversion system, and an energy storage system operatively connected to the energy conversion system;
at least three wheels rotatably mounted with respect to the suspension system; and
a plurality of preassembled modules having vehicular components at least partially forming at least one of the suspension system, the steering system, the braking system, the energy conversion system, and the energy storage system;
wherein the steering system, braking system, and energy conversion system are responsive to nonmechanical control signals and operatively connected to at least one of the wheels;
wherein each of the plurality of preassembled modules is characterized by a module interface having at least one locking or fastening element, wherein said vehicle chassis further comprises a plurality of frame interfaces mounted with respect to the structural frame, each of the plurality of frame interfaces having at least one complementary locking or fastening element engageable with the at least one locking or fastening element in the module interface of one of the plurality of preassembled modules;
wherein the module interface of each of the plurality of preassembled modules is operatively engaged with one of the plurality of frame interfaces such that each of the plurality of preassembled modules is mounted with respect to the structural frame; and
wherein the preassembled modules have module interfaces different from one another; and
wherein each of the plurality of frame interfaces is engageable with the module interface of only one of the plurality of preassembled modules to prevent errors in assembly.

Abstract
A chassis having systems responsive to a nonmechanical control signals and a simplified body-attachment interface includes preassembled modules to enhance ease and simplicity of chassis assembly. The chassis is preferably configured to minimize the possibility of a preassembled module being incorrectly positioned within the chassis. Methods for advantageously employing preassembled modules to assemble vehicle chassis are also provided.
