Abstract

The invention discloses a joint simulation method of a hybrid electric vehicle control strategy. The method comprises the following steps: (1) establishing a whole vehicle simulation model in cuse software, wherein the hardware modules comprise tires, brakes, a differential mechanism, a speed reducer, a gearbox, a driving motor, a generator, an engine and a clutch, the software modules comprise acab module, an ASC antiskid module, a gear shifting program module and a gearbox control program module, and the engine and motor control module is a matlab _ DLL module; (2) establishing a control strategy model in a matlab _ DLL module, simulating VCU control of a whole vehicle, accessing a vehicle speed signal, a clutch signal and a whole vehicle required torque power signal through a matlab interface, and outputting control signals of an engine and a motor; and (3) receiving signals of a motor and an engine in the whole vehicle simulation model from a matlab interface, performing simulation based on two working conditions of NEDC and WLTC, and calculating oil consumption and power consumption per hundred kilometers.

Description

Technical field: [0001] The invention relates to a combined simulation method for a control strategy of a hybrid electric vehicle, which belongs to the field of hybrid electric vehicles. Background technique: [0002] In recent years, as the problems of energy shortage and serious environmental pollution have become more and more prominent, the laws of various countries on energy conservation and environmental protection have become more and more stringent, and new energy vehicles have received more and more attention. Due to the long charging time and continuous driving of pure electric vehicles The two major technical problems of short mileage will seriously affect the convenience of drivers. Hybrid vehicles can not only solve the problem of energy saving and emission reduction, but also achieve a long driving range. They are the most promising new energy vehicles in the future. [0003] At present, simulation software can be used to simulate the control strategy of hybri...
