Abstract
In response to an upshift of a gearshift position SP in a sequential gearshift range, the drive control of the invention once lowers the rotation speed Ne of an engine. This variation in rotation speed of the engine enables the driver to have adequate gear change feeling, which is similar to the familiar gear change feeling in a conventional motor vehicle equipped with a stepped automatic transmission. Namely the drive control of the invention effectively prevents the driver from feeling something is wrong.
