| titleOfInvention | Power split hybrid power system mode switching control method based on state estimation |
| abstract | The invention relates to a mode switching control method of a power split hybrid power system based on state estimation, which aims at the switching of pure electric and hybrid power modes of the power split hybrid power system and comprises the following steps: s1: calculating a motor driving torque meeting the power performance requirement of the whole vehicle on the basis of the torque required by the power output end on the energy management layer; s2: designing an unknown input observer on a coordination control layer to estimate torques of an input shaft and a power output end of the gearbox on line; s3: designing a model predictive control strategy to realize stable start and stop of an engine and solve the start and stop torque of a motor based on the torque estimated value of the input shaft of the gearbox; s4: designing a torque impact suppression strategy based on the torque estimation value of the power output end and solving a motor compensation torque; s5: and superposing the motor driving, start-stop and compensation torques to obtain a motor target torque decision value. Compared with the prior art, the method has the advantages of improving the driving smoothness of the whole vehicle in the mode switching process of the power-split hybrid power system and considering the start-stop performance of the engine. |
