Amtd hybrid transmission upshift point calculation method, device and equipment

Abstract

An AMT hybrid transmission upshift point calculation method, device and equipment, comprising: obtaining the oil-driven fuel consumption rate curve about torque and speed when the AMT hybrid transmission performs each gear switching operation in the oil-driven mode; obtaining the power generation fuel consumption rate curve about torque and speed when each gear switching operation is performed in the power generation driving mode; obtaining the target switching gear, the power generation power of the engine, the total power, the current speed and the current torque in the hybrid mode; according to the proportion of the power generation power of the engine in the total power, the speed and the torque, the upshift speed is determined by interpolating between the oil-driven fuel consumption rate curve and the power generation fuel consumption rate curve corresponding to the target switching gear. For the driving condition of the hybrid mode, according to the proportion of the power generation power of the engine in the total power in the hybrid mode, the optimal upshift point position of the hybrid mode at this time can be determined between the two extreme cases, that is, the optimal upshift speed is determined.
