Abstract: A kind of powertrain structure is introduced which adopts
automated manual transmission (AMT) in the hybrid electric vehicle (HEV).
Automated mechanical transmission in the hybrid electric vehicle has
three problems of wear of synchronizer, wear of cluth and interruption
time of powertrain. It is difficult to solve these problems by
traditional shifting control method. The coordinated powertrain control
method is presented to shorten interruption time of power and to minish
wear of synchronizer and cluth through analyzing the matter and
resolvent of problems. This method is tested and verified in simulating
test, hard-in-loop test and proving ground test. Results of test prove
that the method is effictive.
Key words: Hybrid electric vehicle Automated mechanical
