COORDINATED POWERTRAIN CONTROL METHOD FOR SHIFTING PROCESS OF AUTOMATED MECHANICAL TRANSMISSION IN THE HYBRID ELECTRIC VEHICLE

Abstract

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: Automated mechanical transmission, Coordinated powertrain control, Hybrid electric vehicle, Shift quality
