Embodiment Construction

[0041] figure 1 It is the application topological diagram of the double mechanical port motor of the present invention in the hybrid electric vehicle. like figure 1 As shown, a hybrid electric vehicle equipped with a dual mechanical port motor is mainly composed of two parts: the mechanical body and the electrical control. The double mechanical port motor is a three-layer structure arranged concentrically, the outermost layer is the stator 4, the middle is the outer rotor 5, and the innermost layer is the inner rotor 3. Wherein, armature windings are installed on the stator 4 and the inner rotor 3 . The inner rotor current can be passed into the armature winding of the inner rotor 3 from an external power source through brushes and slip rings. The inner rotor is directly connected to the crankshaft of the internal combustion engine 1 and the inner rotor 3 of the dual mechanical port motor, and a clutch 2 is installed between the inner rotor 3 and the outer rotor 5 of the du...

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. Therefore, under the condition that the battery technology bottleneck has not been broken, it has become the automobile industry in the world at the beginning of the 21st century. important research topic. Patent CN1945939 "Dual Mechanical Port Motor and Its Drive Control System" provides a new type of motor used in hybrid electric vehicle technology, that is, a dual mechanical port motor (DMPM), which consists of a stator and two rotors. The purpose of electric stepless speed change can be realized. When the dual mechanical port motor is used in hybrid vehicle technology, the second m...
