1. A vehicular control system controlling a vehicle device, the vehicular control system comprising:
- a first electric control unit controlling a first function of the vehicle device that is normally required to control the vehicle device; and
a second electric control unit controlling a second function of the vehicle device different than the first function and associated with the first function of the vehicle device, whereinthe first electric control unit and the second electric control unit are in communication and are separately disposed in a vehicle,at least the second electric control unit is removable from the vehicular control system such that controlling the first function of the vehicle device is unaffected by removal of the second electric control unit,the first electric control unit directs control of the first function according to (a) an internal condition of the first electric control unit based on control of the first function of the first electric control unit and (b) an internal condition of the second electric control unit based on the control of the second function by the second electric control unit, andthe first electric control unit receives and uses the internal condition of the second electric control unit to direct control of the first function.

Abstract
A method of preparing a vehicle control system having an intended function by using at least two ECUs is provided. One of the at least two ECUs is used for adaptively incorporating a modified portion of the intended function of the vehicle control system through re-design in a short period, while the rest of the ECUs in the vehicle control system sustain and support an unchanging portion of the intended function of the vehicle control system.
