Regarding the power supply voltage diagnosis strategy, the high-profile instrument controller needs to be consistent with the low-profile instrument controller. However, during actual communication and analysis, it was found that the diagnostic logic and strategy analysis of the low-profile instrument controller related to power voltage was not in place, which affected the high-profile instrument control. device design
[0005] After systematically understanding the current practices of controllers in the prior art, it is found that they are scattered and inconvenient for unification, cross-platform transplantation and management

The invention provides an automobile electronic control unit stability evaluation method and device. The method comprises the following steps: inputting the voltage type and the voltage value of the automotive power supply of the automotive electronic control unit into an automotive electronic control unit program to obtain the voltage state output by the automotive electronic control unit program; wherein the automobile electronic control unit program is obtained on the basis of SIMULINK, and the voltage state comprises voltage undervoltage, voltage normality and voltage overvoltage; and if the voltage state is under-voltage or over-voltage, judging that the automobile electronic control unit is unstable. The embodiment of the invention provides a method and device. Obtaining an automobile electronic control unit program on the basis of SIMULINK; whether the working state of the automobile electronic control unit is stable or not is judged by running an automobile electronic control unit program, a voltage diagnosis and analysis model of a power supply is designed through an SIMULINK model-based design method to generate a code to be compiled into a program, and the method is suitable for software control of all automobile electronic control units.
Description
technical field [0001] The invention relates to the technical field of automotive electronic control, in particular to a method and device for evaluating the stability of an automotive electronic control unit. Background technique [0002] Automotive electronic control technology is changing with each passing day, and more and more automotive electronic control unit nodes are used in complete vehicles. In the increasingly large and complex vehicle electronic architecture and electrical environment, the stability of the automotive electronic control unit is becoming more and more important. [0003] Reasonable diagnosis and analysis of the power supply voltage is the basic condition to ensure the stability of the automotive electronic control unit. How to reasonably analyze the power supply voltage and realize accurate diagnosis is an urgent expectation and requirement of both OEMs and parts suppliers. [0004] In the prior art, when making a high-end instrument controller ...
