Procedure and device for upshift in an automatic or automatized transmission |
摘要 |
The method of gear change control for a motor vehicle automatic transmission uses the vehicle speed and engine output to determine the required transmission gear ratio. The higher gears are released when the engine regime (Nmot) attains a value (Nmax) determined from the gear change commands and variation in the regime during declutching of the transmission. The regime variation is a function of the gear range and the engine speed. |
