CONTROL DEVICE FOR TRANSMISSION AND BRAKING TORQUE GENERATION DETERMINATION METHOD FOR TRANSMISSION |
| 摘要 |
A control device for a transmission including m (m>=3) solenoid valves and configured to establish a plurality of shift speeds by engaging n1 (2@n1<m) engagement elements using hydraulic pressures of nl solenoid valves among the m solenoid valves, the control device. The control device having an actual current value detection unit that detects respective values of actual currents flowing through solenoids of the m solenoid valves; and a determination unit that determines whether or not braking torque is generated on an output shaft of the transmission by comparing the detected actual current values for solenoids of n2 (n1<n2@m) solenoid valves and a current threshold. |
