Abstract

The invention discloses an energy protection method, device and equipment for an AMT clutch and a storage medium. The method comprises the steps that the current temperature and the current sliding friction power limit value of the AMT clutch are obtained; the current temperature is compared with a preset temperature threshold value to obtain a temperature comparison result, and the current sliding friction power limit value is compared with a preset sliding friction threshold value to obtain a sliding friction power comparison result; and a current energy protection working condition is obtained, AMT clutch energy protection is conducted according to the current energy protection working condition, the temperature comparison result and the sliding friction power comparison result, different coping strategies can be adopted for different working conditions, dry wear during friction plate sliding is avoided, the friction heating burden of the clutch is relieved, the wear rate of the clutch is reduced, the safety of the clutch is ensured, and the service life of the clutch is prolonged.

Description

technical field [0001] The invention relates to the technical field of clutch control, in particular to an energy protection method, device, equipment and storage medium for an AMT clutch. Background technique [0002] Automated Mechanical Transmission (AMT) is an important development trend of commercial vehicle gearboxes, and its market share will continue to expand in the future. AMT gearboxes currently use dry clutches, which will wear out at high temperatures The risk of aggravation and ablation, but long life is an important indicator of the AMT clutch. At present, AMT gearboxes generally have a clutch temperature protection function. When the clutch temperature reaches the limit value, the AMT gearbox will immediately give an instrument alarm. [0003] However, from the ablation faults in the actual application of AMT and the results of a large number of clutch tests, even if the clutch temperature is low, a large amount of sliding work (that is, the energy generated ...
