Abstract: Referring
former methods of driver’s intention inference, according to vehicle
dynamics, the balance throttle open on plane and straight road and
relative throttle open are defined. Based on these, driver demand
acceleration characteristics are discussed and driver intentions on
plane and straight road are classified to five relative styles. Driver
usual operation characteristics under these five classic conditions are
summarized. It is proved that driving environment is equivalent to
certain driver intention and they can be integrated to infer. A
multi-input single-output fuzzy reasoning model is established and the
fuzzy rules are based on test data and driver experiences. This model
can be applied to micro controller unit and an improved real-time
algorithm is brought up. Validated with the test data, this model can
infer the intentions quite well.
Key words: Driver’s
