Embodiment 1

[0043]At present, the new energy vehicle operation cloud platform in the industry is basically based on single-core centralized deployment. However, with the rapid development of information technology and the sharp increase in the number of vehicles, the data generated by the real-time system has increased sharply. It is difficult for a single-machine real-time database to handle massive data. Standards for analysis and processing. The use of multi-layer data transmission structure, distributed storage and hierarchical statistical computing technology can significantly improve the system capacity and response speed of the cloud server, and further improve system performance.

[0044] This embodiment provides a cloud platform-based vehicle controller optimization design system, and its overall system functions are implemented as follows: figure 1 As shown, the traffic lights, surrounding environment and other road condition information collected in real time by the vehicle-mou...

Embodiment 2

[0060] Such as image 3 As shown, the present embodiment provides a method for optimizing a vehicle controller based on a cloud platform, including:

[0061] The vehicle controller packs the received real-time road condition information and vehicle status information into a data message and sends it to the cloud platform through the wireless intelligent terminal;

[0062] The cloud platform performs information analysis after receiving the data message transmitted by the wireless smart terminal, and performs information fusion of the analyzed real-time road condition information and vehicle status information to obtain a road condition test data set;

[0063] Based on the road condition prediction model, the road condition prediction is completed with the road condition test data set as input;

[0064] Generate optimal control instructions for vehicle energy management control based on road condition prediction results;

[0065] The optimal control command is sent to the veh...

Abstract

The invention discloses a vehicle control unit optimization system and method based on a cloud platform. The method comprises steps that a vehicle control unit packages the received road condition real-time information and the vehicle state information into a data message and sends the data message to the cloud platform through a wireless intelligent terminal; the cloud platform performs information analysis after receiving the data message transmitted by a wireless intelligent terminal, performs information fusion by utilizing the road condition real-time information and the vehicle state information to complete road condition prediction, performs optimal control on vehicle energy management based on the road condition prediction result, obtains an optimal control strategy and generates acontrol instruction; the cloud platform further sends the control instruction to the vehicle control unit through the wireless intelligent terminal, and the vehicle control unit controls and executesthe control instruction. The method is advantaged in that by means of the powerful cloud platform technology, the data transmission and processing capacity of the whole vehicle control system is improved, and stability, safety and real-time performance of the system can be guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of new energy electric vehicles, in particular to a system and method for optimizing a vehicle controller based on a cloud platform. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Vehicle controller (VCU) is the control core of new energy vehicles, and its performance will affect the economy and safety of new energy vehicles. In the competition with traditional internal combustion engine vehicles, a high-performance vehicle controller is particularly important for new energy vehicles. The performance of the vehicle controller lies in its data transmission and processing efficiency and system stability. For almost all new energy vehicles at present, the road condition information collected during driving, the prediction of future road conditions, the optimizati...
