Method for controlling a motor vehicle's automatic gearbox reduces an engine's torque with an automatic gearbox driven by an internal combustion engine affected by an accelerator pedal

摘要

A signal (HDK) in proportion to an accelerator pedal's position passes to an electronic gearbox control (EGS) storing gearshift programs (SKL,SKLred) with gearshift mapping. Reduction in engine torque is accounted for in a gearshift program selection routine, so that in a quasi-stationary condition and during an approximately full load operation an engine torque reduction factor (kMOMred) acts as an effective variable for selecting the gearshift program.
