Abstract: In order to eliminate the shift-hunting, busy-shift and
skidding occurred in the conventional automatic transmission, a
multi-pattern automatic shift system based on driving environment
recognition is proposed. This system can infer the current driving
environment according to the signals deriving from the conventional
automatic transmission sensors and select the proper shift strategy
correspondingly. Thus, the problems when the vehicle travels in the
specific driving situations can be solved and the vehicle’s driving
performance can be improved effectively. This control method based on
driving environment recognition will be the developing trend of future
automobile control system.
Key words: Driving environment Automatic transmission Shift strategy
