ABSTRACT:
An electromobile equipped with an automatic transmission which may detect a running condition of a vehicle and selects a gear ratio suited for the running condition. In this electromobile, a build-up characteristic of an electric motor current immediately after gear-change is improved, thereby minimizing delay in power transmission so as to shorten a gear-changing duration, in an attempt to improve an operational feeding of a driver at the time of gear change.
