Method of designing and manufacturing vehicles
View Patent ↗An accelerated vehicle development process includes establishing a common, standardized interface system whereby different types of vehicle bodies may be attached to a single chassis design. Chassis and bodies are designed, manufactured and validated independently of each other in accordance with the standardized interface system, thereby accelerating the development process. As new bodies are designed to mate with the previously manufactured and validated chassis, the newly designed bodies may be developed more quickly in response to market demand and attached to the previously validated chassis.
1. A method of designing and manufacturing vehicles comprising:
establishing a standard vehicle chassis design including a structural frame; a suspension system mounted to the structural frame; at least three wheels rotatably mounted to the suspension system; an energy conversion system mounted to the structural frame, operably connected to at least one wheel, controllable by wire; a by-wire braking system mounted to the frame and operably connected to at least one wheel; and a computer operatively connected to the energy conversion system and braking system, wherein said standard vehicle chassis design includes a common, standardized interface system having body connection components arranged to facilitate selective attachment of any of a plurality of different body types to the standard chassis;
manufacturing a plurality of chassis in accordance with said standard vehicle chassis design, independently of vehicle bodies; and
after said step of manufacturing a plurality of chassis, designing and manufacturing a plurality of different bodies having different body types and configured to conform to said standardized interface system for attachment to said manufactured chassis.
2. The method of claim 1 , wherein said different body types are of at least two body categories taken from the group consisting of sedans, pickup trucks, convertibles, coupes, vans, station wagons, sport-utility vehicles, and other types of transports.
3. The method of claim 1 , further comprising, after said step of designing and manufacturing a plurality of bodies, attaching the said manufactured bodies to manufactured chassis.
4. The method of claim 3 , further comprising, after said attaching step, designing and manufacturing additional bodies having body types different from said attached bodies and configured to conform to said standardized interface system for selective attachment to said manufactured chassis.
5. A method of designing and manufacturing vehicles comprising:
predefining a vehicle body-chassis interface system wherein mechanical and electrical connection components are required to be in predetermined spatial positions relative to each other in a body-attachment interface on a chassis and in corresponding predetermined spatial positions relative to each other in a corresponding chassis-attachment interface on any body to be attached to the chassis;
manufacturing vehicle chassis conforming to said predefined vehicle body-chassis interface system,
said vehicle chassis each including a structural frame, a suspension system mounted with respect to the structural frame, at least three wheels rotatably mounted with respect to the suspension system, an energy conversion system mounted with respect to the structural frame, operably connected to at least one wheel, and controllable by wire, and a by-wire braking system mounted with respect to the frame and operably connected to at least one wheel; and
after said step of manufacturing chassis, designing and manufacturing vehicle bodies conforming to said standardized interface system for attachment to said manufactured chassis, said bodies including at least three different body styles.
6. A method of designing and manufacturing vehicles comprising:
establishing a standard vehicle chassis design including a structural frame; a suspension system mounted to the structural frame; at least three wheels ratatably mounted to the suspension system; an energy conversion system mounted to the structural frame, operably connected to at least one wheel, controllable by wire; a by-wire braking system mounted to the frame and operably connected to at least one wheel; and a computer operatively connected to the energy conversion system and braking system, wherein said standard vehicle chassis design includes a common, standardized interface system having body connection components arranged to facilitate selective attachment of any of a plurality of different body types to the standard chassis;
manufacturing a plurality of chassis in accordance with said standard vehicle chassis design, independently of vehicle bodies; and
after said step of manufacturing a plurality of chassis, designing and manufacturing a plurality of different bodies having different body types and configured to conform to said standardized interface system for attachment to said manufactured chassis, wherein said different body types include at least three types of bodies taken from the group consisting of sedans, pick-up trucks, convertibles, coupes, vans, station wagons and sport-utility vehicles.
