Control system for continuously variable transmission |
摘要 |
A control system comprises a line pressure control section which controls a line pressure applied to pulleys of a CVT according to an input load from the engine. When the input load is temporally increased, the line pressure is temporally increased by a pressure increasing section. After the line pressure is held for a predetermined time, the temporally increased line pressure is slowly decompressed by a step amount which is set small according to the increase of a transmission ratio of the CVT. This slow decompression of the line pressure suppresses the generation of vibrations of a drive system. Further, when an anti-skid control apparatus is operating or when a start clutch is engaged by the increase of the line pressure, the slow decompression is cancelled to smoothly execute their operations.
