New energy vehicle entire vehicle matching analysis system, data acquisition method and analysis method

Abstract

The invention belongs to the technical field of a new energy vehicle and particularly relates to a new energy vehicle entire vehicle matching analysis system and a new energy vehicle entire vehicle matching data acquisition method and analysis method. The new energy vehicle comprises an entire vehicle controller, an engine, a generator and a driving motor, the analysis system comprises an embeddedsystem, a remote data access server, a data processing server and a computer, the entire vehicle controller is used for acquiring vehicle work condition parameters, the embedded system can upload theacquired information to the remote data access server, the remote data access server is used for transmitting the received data to the data processing server and storing the data in a database, and the computer is used for analyzing the information in the database. the system is advantaged in that parameter adjustment and calibration of system software of the entire vehicle controller can be carried out according to a power system energy saving optimization scheme under specific actual work conditions, work points of the generator system and the driving motor are made to distribute at the optimal areas, and the economical and energy-saving goal can be realized.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a new energy vehicle vehicle matching analysis system, a data collection method and an analysis method. Background technique [0002] With the continuous development of new energy hybrid power and pure electric vehicle technology at home and abroad, the difficulty of matching the engine and motor hybrid power system has greatly increased. Different matching designs, different regions, different driving habits, and different working conditions will affect the vehicle. Energy consumption and motor efficiency have a direct impact, and the demand for the vehicle R&D environment is increasing. [0003] The prior art discloses a method for matching the power system of an engineering vehicle, the application number of which is CN200810172620.8. The engineering vehicle uses an electronically controlled engine, and the engine calibrates the engine power and engine ...

Problems solved by technology

But the disadvantage is that the working efficiency of the actuators is not taken into account (such as hydraulic pumps, generators, drive motors, etc.), because the low fuel consumption area of ​​the engine corresponds to the efficiency of the actuators at the same speed and torque, which is not necessarily the best area, resulting in There is a corresponding deviation from the ideal state of the optimal matching strategy according to the prior art

[0005] In addition, the amount of information collected by the existing technology is relatively small, and it is impossible to analyze the applicability of the power system matching from the perspective of the vehicle's working conditions and driving habits, and it does not meet the complex conditions of the multiple power modes of the motor, generator, and engine of the new energy vehicle. matching needs
