Rapid adaptation method and system for electric vehicle controller protocol

Abstract

The invention relates to a rapid adaptation method and system for an electric vehicle controller protocol, and the system comprises a controller, an instrument and a terminal, and the rapid adaptation method comprises the steps: enabling the instrument to recognize whether the received controller data is integrated services digital network data, and transmitting the recognized integrated services digital network data to the terminal; the terminal determines a unique analysis program of the integrated service digital network data in the terminal according to the identified message structure of the integrated service digital network data and the vehicle information of the electric vehicle to be adapted; and the terminal matches or updates the unique analysis program with the analysis program in the remote server, and transmits the updated analysis program to the instrument. The method can quickly adapt to various integrated service digital network controllers, so that the compatibility and universality of the liquid crystal instrument to different electric vehicle factory controllers are improved, and the updating process is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of communication between electric vehicles and instruments, and in particular relates to a method and system for fast adaptation of an electric vehicle controller protocol. Background technique [0002] At present, domestic two-wheeled electric vehicle and electric motorcycle manufacturers will use the one-line communication method to communicate information between the controller and the LCD instrument. Although the international standard SIF (source-input-format, sif) communication protocol is adopted between the interfaces, and the level also complies with the TTL (Transistor-Transistor-Logic, triode logic) specification, it can only maintain the one-line power-on interface. Universality. [0003] The initial physical level is high level or low level, as well as the length of the data sent, the number of bytes, the data analysis method, all these must require the first-line communication controller provi...

[0003] Whether the initial physical level is high or low, the number of bytes of data to be sent, and the data analysis method, all of these must require the provider of the one-line communication controller to inform the LCD instrument factory in advance, and the instrument factory will follow the control Modify the host code of the instrument according to the data attributes and data encryption methods of the instrument, recompile and generate the burn-in image, and re-burn the new image software to ensure that the instrument can communicate with the controller normally, so as to ensure that the LCD instrument of the electric vehicle can be normal Display the vehicle body information such as speed, gear position, and fault sent by the controller, but the adaptation period between this LCD instrument and the electric vehicle controller is long, the modification is difficult, the adaptation process is complicated, and the adaptation method is only suitable for the front of the car factory. The installation market cannot meet the needs of the LCD instrument aftermarket
