Control method for hybrid power automobile equipped with two mechanical end motors

Abstract

The invention relates to a control method of an electric motor hybrid power car loaded with dual mechanical ports, wherein, the switching of car working modes is controlled by an entire car control unit, and the power of the entire car is distributed according to the information of gears and accelerator pedals, the power Pa required by auxiliary equipment on the car, the nominal torque and the actual rotation speed value of an inner electric motor and an external electric motor of the dual-mechanical port electric motor, the throttle percentage of an internal combustion engine and the nominal power which the internal combustion engine can provide and the state of the charge of batteries sent by a battery control unit; in the reversing process and the running process, the torque Tm of the external electric motor and the rotation speed Omega of the inner electric motor of the dual-mechanical port electric motor which are calculated by the entire car control unit are sent to the controller of the dual-mechanical port electric motor to control the dual-mechanical port electric motor, and the power P provided by the internal combustion engine is sent to a control unit of the internal combustion engine to control the throttle percentage of the internal combustion engine; the torque T of energy recovery is sent to the external electric motor of the dual-mechanical port electric motor by the entire car control unit in the braking process; the braking control value is sent to the controller of the dual-mechanical port electric motor when the car is stopped and generates electricity.

Description

technical field [0001] The invention relates to a control method of a hybrid electric vehicle loaded with dual mechanical port motors. Background technique [0002] Hybrid electric vehicles can not only give full play to the advantages of ultra-low emissions of electric vehicles, but also maintain the characteristics of high specific energy of traditional internal combustion engine vehicles.
