Problems solved by technology

[0004] 2) The synchronization requirements of the two programming are high and the process is cumbersome, and improper handling will cause the system to fail to work normally;
[0005] 3) A complete programming process includes two programmings, both of which need to be connected to the programming device. The programming process has many steps and low efficiency, which is not conducive to the mass production of the controller and the program update after production.

Embodiment Construction

[0022] Such as figure 1 As shown, the vehicle-mounted controller includes a main control chip and a safety monitoring chip. The main control chip is used to realize the main control function of the controller. The safety monitoring chip and the main control chip monitor each other's working status to ensure the safety and reliability of the entire controller. In the first operation, both chips need to burn corresponding program codes to realize their respective functions. In the multi-chip application programming mode, the entire controller only needs to provide a program burning interface for the main control chip. First, the program of the main control chip and the safety monitoring chip can be burned into the Flash of the main control chip through this interface. Then the main control chip burns the safety monitoring code into the safety monitoring chip through the application programming module, and finally completes the program burning of the entire controller;

Abstract

The invention discloses a method for programming a multi-chip application program of a vehicle-mounted controller, which includes: division of the address space of the main control chip and segmented storage of codes, integration of the code of the main control chip and the code of the safety monitoring chip, and The application programming module in the chip code burns the code of the security monitoring chip into the security monitoring chip. The present invention can complete the downloading and updating of the codes of the main control chip and the safety monitoring chip through a program burning process.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a method for programming a multi-chip application program of a vehicle-mounted controller. Background technique [0002] In the development of vehicle-mounted controllers, the control system must meet the requirements of high safety and high reliability. One technical solution is to use multiple processing chips in the control system to realize the safety monitoring function: the main control chip realizes the control of the controller. The main control function, the cooperation and mutual monitoring between the safety monitoring chip and the main control chip, ensures the safe and reliable operation of the entire control system. However, when the security monitoring chip is added to the controller, both the main control chip and the security monitoring chip need to be programmed. If each chip is simply programmed separately, there will be the following problems: [0003] 1) The progr...
