Abstract: The
optimum valve generator is set up by the radial basis function network
and fuzzy controller is given for variable valve timing (VVT) system of
automotive engine. It has been proved by vehicle road test that the
system has a better static and dynamic performance, and good
reliability. The equal speed fuel consumption of automobile is reduced
by 10% over no-install VVT at high speed. The acceleration time on
direct speed is reduced by 4.8% over no-install VVT. The minimal stabile
speed of automobile is reduced by 8.3% over no-install VVT.
