Study on the Synchronizing Time and Shift Quality of Automated Manual Transmission (AMT)

Abstract:

By the synchronizing time, the synchronizing force was controlled reasonably. The impact factors on synchronizing were analyzed and the shift synchronization time was studied. The benchmarking and the road tests were carried out for further investigation. Test data show that by the developed AMT shift control strategies, the average synchronization time is as follows: under the benchmarking condition the minimum time is 100ms (3->4 gear) while the maximum time is 485 ms (0->1 gear); under the road test condition the minimum time is 55ms (4->5 gear) while the maximum time is 100 ms (3->4 gear); The jerk as the utility comfort evaluation index under the road test condition was analyzed and the result was 5.43 m/s3 which satisfied the automated transmission requirement perfectly.
