A power output method and system

Abstract

The embodiment of the invention provides a power output method and system. The power output method comprises the following steps: obtaining hardware parameters, selecting performance indexes and testing road conditions, dividing operation time into a plurality of basic time intervals, using the hardware parameters and the testing road conditions to calculate target values of the performance indexes in the basic time intervals, selecting power standards in the basic time intervals according to the target values of the performance indexes, and using power standard combinations corresponding to the basic time intervals as a power output scheme according to time sequences. The power output system comprises a performance module, a standard module and a combination module, wherein the performance module is used for obtaining the hardware parameters, selecting the performance indexes and the testing road conditions, dividing the operation time into the multiple basic time intervals and using the hardware parameters and the testing road conditions to calculate the target values of the performance indexes in the basic time intervals, the standard module is used for selecting the power standards in the basic time intervals according to the target values of the performance indexes, and the combination module is used for using the power standard combination corresponding to the basic time intervals as the power output scheme according to the time sequences.

Description

technical field [0001] The present invention relates to the technical field of hybrid vehicles, in particular to a power output method and system. Background technique [0002] Hybrid vehicles (also known as hybrid vehicles) refer to vehicles with at least two power sources. At present, hybrid vehicles often use traditional internal combustion engines as the main power source. In addition to internal combustion engines, batteries and fuel cells are also installed. , solar cells or internal combustion engine generator sets, etc., auxiliary power sources in the form of electricity. At present, the most common form of hybrid vehicle is a vehicle powered by an internal combustion engine, a generator and a battery. [0003] It is precisely because there are at least two power sources in hybrid vehicles, and the distribution ratio of each power source will affect the performance indicators of the vehicle (such as minimum fuel consumption, maximum speed or acceleration, etc.), so ...

Problems solved by technology

However, the defect of the existing technology is that the power output method obtained according to the above mathematical model is only a static result obtained by balancing the states at each moment, and cannot change the power output at any time with the passage of time, so the effect does not approach the theory In addition, the existing mathematical model calculation method can only be calculated for one hardware configuration and one fixed performance index at a time. If there are parameters in the mathematical model changed, it must be Complicated repeated calculations cannot be easily and widely applied
