The invention provides an AMT (automated mechanical transmission) clutch starting control method, an AMT clutch starting control system and a vehicle, belongs to the technical field of commercial vehicle control, and optimizes PID (proportion integration differentiation) control parameters in a clutch actuating mechanism based on starting clutch torque in combination with clutch transmission torque curves at different oil temperatures. When the target vehicle meets the starting condition, the target torque of clutch control is determined; according to the selected driving mode, in combination with the accelerator opening degree, the accelerator change rate signal and the target torque, the starting action is executed, the closed-loop adjusting torque of the clutch is analyzed, and a clutch executing mechanism is controlled to operate through the optimized PID control parameters. Correction of the clutch stroke position on PID parameters is added, meanwhile, the I parameter adjusting range is optimized, accurate control over the clutch position is achieved, meanwhile, clutch abrasion can be reduced, and the service life of the clutch is prolonged.
