METHOD FOR COORDINATED CONTROL OF VEHICLE ELECTROMECHANICAL DRIVELINE Russian patent published in 2015 - IPC B60L15/20 B60L11/08 B60W20/00 B60W10/00 

FIELD: transport.

SUBSTANCE: in the method, minimum and maximum parameters of each traction motor, motor generator, thermal engine, traction motors are prespecified. For each thermal engine, required rotational speed value versus required power relationship and net torque versus required or actual speed of engine rotation relationship is specified. At every instant, required value of traction motors total electromagnetic torque is specified which value is distributed between traction motors determining required moment for each of them. Following parameters are determined: DC bus voltage, rotational speeds of motor-generators, traction motors, thermal engines, required power for each traction motor, value of total power of motor-generators, required for this total power generation quantity of thermal engines and associated motor-generators. Required value of total motor-generator power is distributed between thermal engines. Following parameters are determined: required rotational speed of thermal engine, total electromagnetic torque which should be provided by motor-generators driven by a-th thermal engine, difference between actual and required rotational speed of each thermal engine, total electromagnetic torque which should be provided by all motor-generators, and feasible value of total electromagnetic torque of all motor-generators. This feasible value is distributed between motor-generators, determining feasible electromagnetic torque of each of them. Feasible value of total electromagnetic torque of traction motors is determined and feasible value of total electromagnetic torque is distributed between traction motors, determining feasible torque of each of them. Electromagnetic torque of each traction motor and electromagnetic torque of each motor-generator is created.

EFFECT: electric machine torque soft limiting preventing electromechanical driveline operating parameters from falling outside permissible limits, optimal distribution of power flows, optimal operation of electromechanical driveline.
