Abstract

A method and system for automatically generating panel layout and wiring harness specifications for vehicles. The panel layout system receives as input a list of parts including switches, gauges, connectors, circuit breakers, etc., and automatically places these parts in a control panel (e.g. dash panel or electrical panel) within the vehicle. To place these parts automatically, the system extracts potential panel locations for each part from a database, and then attempts to place the parts in their corresponding potential panel locations. The system can also generate a wiring specification for the vehicle. Once panel locations are assigned, the system attempts to assign circuits in the wiring harness to electrical contact locations associated with panel locations.

Claims

1. A computer implemented method for generating a control panel layout design for a vehicle panel comprising:

displaying a user interface which enables a user to specify potential panel locations;

in response to input from the user specifying the potential panel locations, updating a panel location database for storing the potential panel locations;

reading a part list including a plurality of parts for a vehicle;

for each part in the list, automatically extracting panel location data including a part priority, a plurality of potential panel locations and associated panel location priorities corresponding to each part from the panel location database;

automatically determining a panel location for each part in order of the priority of each part including attempting to locate a current part at a first panel location of the corresponding potential panel locations for the current part, and if the first panel location is occupied, attempting to locate the current part at a second panel location of the corresponding panel locations for the part, and automatically repeating the attempts to locate the current part until a panel location is assigned or it is determined that none of the potential panel locations are available; and

generating a panel layout design for the vehicle including a list of parts and corresponding panel location for each part.
