Abstract

The invention discloses an updating method and system for a vehicle-mounted electronic control unit module. The method comprises the following steps of reading out a first piece of record from a preset profile which comprises multiple pieces of record as current record, wherein each piece of the record at least comprises an instruction and a skipping manner; and an instruction sending step comprising: obtaining an instruction contained in the current record as the current instruction and sending the current instruction to the vehicle-mounted electronic control unit module; obtaining a module response value returned by the vehicle-mounted electronic control unit module in response to the current instruction as a current module response value; obtaining the skipping manner contained in the current record as the current skipping manner; and if the current skipping manner comprises a next piece of record corresponding to the current module response value, updating the current record as the next record, and executing the instruction sending step, else finishing the step. According to the updating method disclosed by the invention, the reutilization rate is increased, and the developing cycle is shortened.

Description

technical field [0001] The invention relates to the related technical field of vehicle-mounted electronic control units, in particular to a method and system for refreshing a vehicle-mounted electronic control unit module. Background technique [0002] As early as 1994, ISO formulated ISO14230. Before 2008, ISO14230 was a diagnostic communication standard adopted by many domestic automobile manufacturers, and it was based on K-line diagnosis. However, with the phase-out of the K line and the rise of the CAN network, most OEMs have transitioned to the ISO15765-based diagnostic protocol. However, with the development of vehicle-mounted networks, multiple networks such as MOST, FlexRay, and wireless networks coexist. In order to unify the diagnostic services of different networks, ISO has formulated a new diagnostic communication protocol, ISO14229-1, also called Unified diagnostic services (UDS). The UDS service is not only used in the currently popular CAN network, but also...
