1. Apparatus for indicating vehicle driving condition states in a computer based controller comprising:
- a memory device including predetermined bit positions for storing binary codes of a predetermined bit length; and
at least one valid binary code corresponding to a vehicle driving condition state;
wherein each valid binary code is characterized by a predetermined ratio of corresponding bit states and is differentiated from all other valid binary codes by differences between at least two complementary bits of each respective valid binary code.

Abstract
A vehicle includes a semi-active suspension including suspension dampers controllably adjustable in accordance with electronic stability control commands and ride and handling commands. Vehicle steering response states, turning direction states and vehicle dynamics states are binary coded in respective state variables and suspension control calibrations are binary coded in calibration words. Integrity and security of state variables and calibration words are ensured in efficient binary digit resource allocation schemes.

10. Method for indicating vehicle driving condition states within a memory device of a computer based controller comprising:
-
providing a first binary coded, variable for conveying vehicle steering response states wherein valid binary codes share a first ratio of individual bit states and are differentiated one from another by differences between at least two complementary bits;
providing a second binary coded variable for conveying vehicle turning direction states wherein valid binary codes share a second ratio of individual bit states and are differentiated one from another by differences between at least two complementary bits; and
providing a third binary coded variable for conveying vehicle dynamics states based on combinations of vehicle steering response and turning direction states wherein valid binary codes share a third ratio of individual bit states and are differentiated one from another by differences between at least two complementary bits. - View Dependent Claims (11, 12, 13, 14, 15)
