Abstract
A managing method for the output power of power system of the car with mixed features that the total output torque on the output axle of speed variator, which is required by the driver, is calculated by the vehicle control unit according to speed and the openness of acceleration pedal, and then is distributed to engine and motor according to the share coefficient of engine.
Description
Technical field
The present invention relates to the control method of hybrid power automobile power system, particularly relate to a kind of kinetic system outputting power management of mixed-kinetic automobile.
Background technology
Along with becoming increasingly conspicuous of global environment and energy problem, the new automobile of exploitation anti-emission carburetor, low oil consumption becomes the top priority of current automobile industry development.The mixed power electric car technology has been avoided the deficiency of pure electric automobile on battery technology and energy Infrastructure, is a good solution of current problem, has become the focus of current international automobile research and development.
Power output and reasonable distribution thereof how to control driving engine and two kinds of propulsions source of motor are one of important contents of hybrid vehicle research, and it directly affects the driving sensation and the travelling comfort of car load.At present, in parallel hybrid electric, driving engine adopts throttle opening value, motor to adopt current value control power output separately, because the relation of two Be Controlled parameter disunities and this two parameters and moment of torsion output valve all be non-linear, institute thinks and reaches the control theory that the total moment of torsion of pulsation-free hybrid power system is exported the needs complexity.
Summary of the invention
The object of the present invention is to provide a kind of kinetic system outputting power management of mixed-kinetic automobile, simplify control theory, no matter be driving engine individual drive, motor individual drive or both common drivings, the driving torque of vehicle ' equates under the condition of the identical speed of a motor vehicle and identical acceleration pedal opening value, thereby has guaranteed the stationarity of moment of torsion output and good driving sensation and travelling comfort.
Technical scheme of the present invention is achieved in that kinetic system outputting power management of mixed-kinetic automobile, be to be carrier with the entire car controller, realize by the control system that comprises compositions such as entire car controller, driving engine and control unit thereof, motor and controller thereof, battery and administrative unit thereof, car speed sensor, acceleration pedal jaw opening sensor; It is characterized in that: the information that entire car controller provides according to car speed sensor, acceleration pedal jaw opening sensor, obtain driver requested hybrid power system total output torque on transmission output shaft by the functional relation of the total output torque of hybrid power system and the speed of a motor vehicle, acceleration pedal opening value, share coefficient by engine torque afterwards, total output torque distributed to driving engine and motor with following formula:
