Pre-charge control system of automatic transmission |
摘要 |
A control system for controlling operation of a pre-charge system of an automatic transmission. The control system comprises a first section which receives first and second gear change instructions which are issued in succession. The first and second gear change instructions are of a type of needing an engaged condition of a same friction element. The control system further comprises a second section which, when the second gear change instruction is issued during a pre-charge period of the friction element which is needed by the first gear change instruction, extends the pre-charge period of the friction element to a time when a pre-charge period needed by the second gear change instruction lapses.
