Abstract

The invention provides a hybrid power dynamic control method and a vehicle. The hybrid power dynamic control method comprises the steps that according to the SOC of a power battery of the hybrid electric vehicle, the power battery is subjected to charge mode dividing; traveling parameters of the hybrid electric vehicle are obtained, and according to the traveling parameters, expected torque of a front-axle belt-type generator and a driving rear-axle motor is obtained; according to the charge mode of the power battery, the expected torque of the front-axle belt-type generator and the expected torque of the driving rear-axle motor, hybrid power output of the engine and a driving motor is controlled; and the driving motor comprises the front-axle belt-type generator and the driving rear-axlemotor. The problem that in the prior art, a hybrid electric vehicle cannot save energy and reduce emission during mutual cooperation of battery driving and fuel driving is solved.

Description

technical field [0001] The invention relates to the automobile field, and relates to a hybrid dynamic control method and device. Background technique [0002] Due to the increasing energy crisis and air pollution, the state has introduced a series of energy-saving and emission-reduction measures, and introduced stricter emission regulations for the automobile industry, thus promoting the development of new energy vehicles. At present, pure electric vehicles are an ideal development goal, but limited by the relatively backward technical status of power batteries, it is still difficult to ensure the two factors of vehicle power and battery life for pure electric vehicles. Therefore, hybrid electric vehicles, which combine the advantages of traditional vehicles and pure electric vehicles, are the mainstream of development at present. [0003] In the process of using a hybrid car, if the car is driven by fuel, when the engine works in an uneconomical area, that is, when the veh...
