Control system and method utilizing generic modules
First Claim
1. A method for performing a control function in a vehicle having a plurality of sensors and actuators, a trunkline for providing power distribution and at least one communication channel throughout the vehicle, a first control module coupled to the trunkline and the plurality of sensors and actuators, and at least one additional control module coupled to the trunkline, the method comprising:
- locating the first control module proximate to the plurality of sensors and actuators so as to reduce point-to-point connection lengths; and
distributing the control function among the first control module and the at least one additional control module based on a required response time of the control function.

Abstract
A control system and method for motor vehicles uses generic control modules which communicate over a vehicle trunkline to accommodate applications of varying functional content and complexity. The vehicle trunkline provides power distribution and a number of communication channels for the various generic control modules which include controller modules, interface modules, and combination controller/interface modules. Each generic control module is connected to the vehicle trunkline via a standardized connector. The combination modules and interface modules are connected to system actuators and sensors with relatively short, simple overlay wiring. The system allows distributed computation for the control of functions and utilizes communication networks to reduce the number of conductors required while increasing the utilization of processing capabilities.
