Summary: | The invention relates to a bulldozer torque converter locking and unlocking control method which comprises the following steps: acquiring first corresponding relation data between a turbine speed and a turbine output torque of a torque converter at a locked state; acquiring second corresponding relation data between the turbine speed and the turbine output torque of a torque converter at an unlocked state; searching an overlapping point turbine speed corresponding to an overlapping point in the first corresponding relation data and the second corresponding relation data; calculating a critical engine speed corresponding to the overlapping point turbine speed according to preset corresponding relation data between the turbine speed and the engine speed; and monitoring locking and unlocking of the engine speed torque converter. According to the bulldozer torque converter locking and unlocking control method, the detection of the turbine speed under a locked condition of the torque converter is converted into de |
