System and method for detecting and responding to pressure losses in a hydraulic automatic transmission |
摘要 |
A control system for a hydraulic automatic transmission includes a fault detection module and a transmission diagnostic module. The fault detection module detects faults of components of the transmission, wherein the faults may indicate low hydraulic fluid pressure in the transmission or failure of one or more of the components. The transmission diagnostic module determines whether the faults are due to low hydraulic pressure based on the detected faults, a predetermined number of faults, and a plurality of conditions. |
