System for discriminating operating state of vehicle clutch mechanism |
摘要 |
A system for discriminating operation state of a lockup clutch of a torque converter of a transmission of a vehicle, more particularly to a system for detection a lockup clutch failure. In the system, three discrimination areas are preestablished with respect to the throttle opening and vehicle speed and reference value are determined in response to a selected discrimination area. The converter slip ratio is compared with the data and when the ratio is out of a range determined by the data, the lockup clutch operation is discriminated to be not normal. At that time, however, when the area is in a weak-engaged region, the engaging force is forcibly increased and the discrimination is conducted once again, thereby making it possible to conduct failure detection in the slip-engaged region and enhancing detection accuracy.
