[0048] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, where the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principle of the present invention.
[0049] A clutch self-calibration method for a hybrid electric vehicle. The specific steps of the clutch self-calibration method are as follows:
[0050] S1. Determine whether the hybrid electric vehicle meets the self-calibration condition. The self-learning conditions include: the cumulative deviation between the clutch position measured by the displacement sensor and the clutch position at the last calibration of the TCU exceeds the allowable range (within the range, it can be considered that all the torque output by the engine can be transmitted to the transmission); The switch is in the OFF position. Although the key switch is in the OFF position, the vehi...
