Abstract

The invention discloses a power assembly testing platform based on power data driving. The power assembly testing platform comprises a dynamometer controller, a first dynamometer, a first torque rotating speed sensor, a speed reducer, a second torque rotating speed sensor and a second dynamometer which are sequentially connected; the speed reducer is connected with a tested motor, the tested motoris controlled through a motor controller, the motor controller is connected with a power battery, and the power battery is used for providing electric energy; the power assembly testing platform further comprises a vehicle model, a wheel and tire model, road models, a driver model, a throttle model and road spectra; and the vehicle model, the wheel and tire model, the road model and the driver model are used for providing simulation functions based on a rack. According to the power assembly testing platform, the problem that matching verification of each subsystem of simulation variable working condition vehicles under variable parameters cannot be achieved in the prior art can be solved through a method of customizing driving working conditions and by combining the various road spectra,the various road models and the like which operate in the rack.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a power assembly testing platform driven by power data. Background technique [0002] With the rapid development of the automobile industry and the continuous improvement of people's living conditions, automobiles have become one of the indispensable means of transportation for people. The number of cars is increasing year by year, and more and more people own private cars. With the depletion of oil resources and the enhancement of people's awareness of environmental protection, traditional fuel vehicles have gradually changed to new energy vehicles. [0003] New energy vehicles include pure electric, hybrid and fuel cell vehicles, etc. For new energy vehicles that use motors and batteries as electric drive and energy recovery devices, their electric drive systems generally include drive motors and motor controllers, among which drive motors It is the active power of ...
