Embodiment Construction

[0061] In order to make the purpose and technical solution of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0062] The communication messages described in Table 1-1 are used between the system and electric vehicles.

[0063] Table 1-1 Communication message format

[0064]

[0065] Note: Since the data obtained by network communication and electric vehicles are all in the form of byte streams, the data larger than 8 bits needs to be split, and the Intel format is uniformly used here.

[0066] The system first sends a seed request to the electric vehicle, and the electric vehicle provides seeds to the system after receiving the request. After receiving the seed response, the system generates a key and sends it to the electric vehicle. T...

Abstract

The invention provides an electric vehicle big data analysis optimizing system and method. The system comprises an electric vehicle database, an algorithm module assembly and a control parameter database, wherein the electric vehicle database receives and stores data transmitted by an electric vehicle controller through a mobile data module supporting 3G communication, the algorithm module assembly accesses the electric vehicle database according to a corresponding algorithm and generates new control parameters to be retained in the control parameter database according to a logic strategy adopted by the algorithm till the new control parameters are covered, the parameters are transmitted to the electric vehicle controller through the mobile data module, and constant optimization of the control parameters of the controller is achieved. The electric vehicle big data analysis optimizing system adopts modular programming, and the modules can be independently used and can be flexibly and conveniently also combined for usage. The rich and online electric vehicle data makes constant control parameter update and ensuring of always efficient and comfortable operation of a vehicle possible.

Description

technical field [0001] The invention relates to the field of electric vehicles, and provides a big data analysis and optimization system and method for electric vehicles. Background technique [0002] Electric vehicles are mainly composed of power supply, drive motor, braking device, charging device and auxiliary devices. Among them, the vehicle controller and its control software realize the unified coordination and control of the battery, motor and other electronic devices of the electric vehicle, and are the command center of the electric vehicle. The control parameter map ("MAP") of the traditional new energy vehicle control unit is solidified in the FLASH area of ​​the control unit in the form of an array variable at the factory. The MAP parameters are obtained through a large number of manual calibration experiments on individual vehicles. Therefore, for mass-produced vehicles, the control parameters do not have the optimal generality of the operating environment and ...
