Title:
自動変速機の制御方法
Document Type and Number:
Japanese Patent JP4698836
Kind Code:
B2
Abstract:
The invention relates to a method for controlling an automatic transmission wherein several shift programs are provided and allocated to specific values of a driving activity characteristic (FAKG) and in each shift program shifting characteristic lines and shifting rotational speeds are determined by accelerator pedal positions. The shifting rotational speeds are immediately increased to higher rotational speeds when the driver quickly depresses the accelerator pedal causing the accelerator pedal position gradient to exceed a presettable limit value. According to the invention, it is proposed that the shifting rotational speeds be determined according to the actual value of the driving activity characteristic by interpolation between shifting characteristic lines from two respective adjacent shift programs and the driving activity characteristic be immediately increased by a presettable offset amount when the accelerator pedal position gradient exceeds the presettable limit value.
