Continuously variable transmission and control method for continuously variable transmission |
摘要 |
When a vehicle decelerates rapidly, a lower limit secondary pulley pressure (Plmt) is calculated on the basis of a primary pulley rotation speed (Npri) detected by a primary pulley rotation sensor. When a deceleration speed (Gdata) is greater than a predetermined deceleration speed (G1) and a secondary pulley pressure (Psec) detected by a secondary pulley pressure sensor is lower than the lower limit secondary pulley pressure (Plmt), it is determined that slippage is about to occur in a V-belt 4 on a primary pulley side in particular, and therefore speed ratio fixing control is performed. |
