| 摘要 |
A system for a vehicle includes an engine torque module, a torque detection module, a torque estimation module, a torque monitoring module, and a diagnostic module. The engine torque module generates a first estimated torque signal based on engine signals and/or GPS signals. The torque detection module generates an actual torque signal of a transmission. The torque estimation module generates a second estimated torque signal based on the first estimated torque signal and/or vehicle/engine values. The diagnostic module detects a fault of a torque sensor based on a torque difference between the actual torque signal and the second estimated torque signal. The torque monitoring module generates a first and a second torque signals based on actual torque signals that represent a lowest and a highest torque values respectively over a predetermined period. The diagnostic module detects the fault based on a torque difference the first and the second torque signals.
