Problems solved by technology

[0004] In view of the problems existing in the prior art, the present invention aims to improve the simultaneous update of multiple ECU or actuator (Actuator) software due to the fact that the LIN network is not a complete multi-master communication (Multi Master Communication) mode, and the transmission speed is relatively low, only 20kbps It solves the problem that the data transmission time and ID efficiency are greatly reduced, and improves the function and efficiency of updating the bootloader (Bootloader) of the microcomputer software built in the ECU or actuator (Actuator) on the vehicle LIN network, thereby providing an effective application transmission. Time and communication resources required for data, while minimizing communication interference between units, Lin network multi-channel boot loader that supports software reprogramming function of multiple same target units (Target Unit) and its operating method

Abstract

The invention relates to a Lin network multichannel guide installation device and an operation method thereof. The Lin network multichannel guide installation device is characterized in that function and efficiency of a bootstrap program of microcomputer software of an ECU or built-in actuator on a vehicle LIN network are improved and updated; and time and communication resources for data transmission are effectively used; communication interference among units is minimized at the same time, so that multiple software reprogramming functions of the same object are supported.

Description

technical field [0001] The invention relates to a Lin network multi-channel guide loading device and an operating method thereof, in particular to a device and a method for downloading a program in a Lin network field unit of a vehicle. Background technique [0002] The LIN network of the vehicle is shown in Figure 1, and generally consists of a master control unit and multiple slave (Slave) units. Each slave unit has a built-in MCU that is not a simple actuator (Actuator). When using embedded (embedded) SW, for SW reprogramming, it is necessary to disassemble the vehicle or cut off the intermediate LIN communication line before implementing SW reprogramming. Moreover, due to the stability of data transmission and reprogramming time, only one slave unit can be reprogrammed at a time. If the embedded software of multiple slave units is reprogrammed, reprogramming may not be possible due to problems such as vehicle wiring or installation location. Especially for the boot ins...
