Vehicle control system with redundant storage of vehicle control parameters
First Claim
1. A control system for electronically controlled vehicle dynamics control systems and ride control systems, said control system comprising:
- a system electronic control unit having a memory;
a display unit having a memory;
vehicle parameters stored in the memory of said system electronic control unit and in the memory of said display unit;
a communications link by which the memory of said system electronic control unit and the memory of said display unit are communicable;
wherein when one of said system electronic control unit and said display unit is replaced, the other of said system electronic control unit and said display unit communicates via said communications link the vehicle parameters stored in the memory thereof to the replaced one of said system electronic control unit and said display unit;
wherein the vehicle parameters stored on at least one of said system electronic control unit and said display unit are user modifiable; and
wherein when the vehicle parameters stored on one of said system electronic control unit and said display unit are modified by a user, the one of said system electronic control unit and said display unit on which the vehicle parameters were modified communicates via said communications link the modified vehicle parameters to the other one of said system electronic control unit and said display unit.

Abstract
A control system for electronically controlled vehicle dynamics control systems and ride control systems includes a system ECU and a diagnostics ECU, each having a memory with vehicle parameters stored thereon. When one of the system ECU and the diagnostics ECU is replaced, the other one communicates via a communications link the vehicle parameters stored in the memory thereof to the replaced one of the system ECU and the diagnostics ECU. The vehicle parameters stored on at least one of the system ECU and the diagnostics ECU are user modifiable, and when the vehicle parameters stored on one of the system ECU and the diagnostics ECU are modified by a user, the one of the system ECU and the diagnostics ECU on which the vehicle parameters were modified communicates via the communications link the modified vehicle parameters to the other one.

12. A method for controlling electronically controlled vehicle dynamics control systems and ride control systems, said method comprising the steps of:
-
providing a system electronic control unit having a memory;
providing a display unit having a memory;
storing vehicle parameters on the memory of the system electronic control unit and one the memory of the display unit;
replacing one of the system electronic control unit and the display unit;
communicating via a communications link the vehicle parameters stored in the memory of the non-replaced one of the system electronic control unit and the display unit to the replaced one of the system electronic control unit and the display unit;
modifying the vehicle parameters stored on one of the system electronic control unit and the display; and
communicating via the communications link the modified vehicle parameters stored in the memory of one of the system electronic control unit and the display unit on which the vehicle parameters were modified to the other one of the system electronic control unit and the display unit. - View Dependent Claims (13, 14, 15, 16, 17, 18)
