Problems solved by technology

[0004] In practical applications, it is found that the programming tool developed using the CCP calibration protocol, because the CCP protocol uses CRO and DTO (Data Transfer Object, data transfer object) instructions to communicate in a corresponding interactive way, the length of the CAN message and the baud rate must be constant. In the case of increased data transmission time, thereby reducing the transmission speed

Abstract

The invention provides a programming device of a vehicle controller. The programming device comprises a communication interface which is a controller local area network CAN bus interface and connected with the vehicle controller, and a controller, the controller sends a transmission mode starting instruction to the vehicle controller via the communication interface so as to control the Boot loader of the vehicle controller to enter a transmission mode, and then analyzes an application program file to be programmed to obtain data information and sends the data information to the vehicle controller by virtue of a predetermined number of continuous data frames to program the vehicle controller. The programming device of the vehicle controller is compatible with a plurality of CAN communication conversion tools, and capable of checking and recording CAN data in real time and displaying the CAN data by virtue of a progress bar. Under the circumferences of a certain Baud rate and the same application file, in contrast with a programming tool based on CCP (CAN Calibration Protocol), the programming device of the vehicle controller has the advantages of few response times of the controller, short data transmission time and high working efficiency.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a programming device for a vehicle controller. Background technique [0002] At present, the online update of the automotive controller application program is carried out using calibration tools such as ETAS (Etuo Agent Server) or VECTOR (dynamic array), and only specific CAN (Controller Area Network, controller local area network) communication conversion can be used. tools, and the software price is relatively high and the code is closed, which is not conducive to independent customization and development. [0003] At present, the automotive controller uses the CAN bus CCP (CAN Calibration Protocol, CAN bus calibration protocol) protocol to update the application program file online, and the PC (personal computer, personal computer) software communicates with the controller bootloader (system boot loader) through the CCP protocol. Perform communication, analyz...
