1. An integrated chassis control system for a vehicle having at least one vehicle subsystem, comprising:
- at least one sensor for sensing at least one vehicle parameter;
at least one vehicle control system for adjusting the at least one vehicle subsystem;
a driving mode switch for selecting at least one driving mode; and
a controller responsive to said at least one sensor and said driving mode switch, said controller for controlling said at least one vehicle control system in accordance with said at least one driving mode;
wherein said driving mode switch has at least two positions for signaling said controller to adjust a plurality of said at least one vehicle control system, resulting in the adjustment of a plurality of said at least one vehicle subsystem between a first driving mode and a second driving mode, said at least two positions comprising a normal position and a sporty position; and
wherein said controller comprises a stability flag register settable to OFF and ON for indicating a stable condition for switching between said first driving mode and said second driving mode.
