Engine electronic control redundant system

Abstract

The invention discloses an engine electronic control redundant system. The engine electronic control redundant system comprises a main ECU, an auxiliary ECU, a first detecting assembly, a second detecting assembly, a first executing assembly, a second executing assembly and a switching box, wherein the first detecting assembly and the second detecting assembly are used for monitoring parameters oftwo sides of a V-type internal combustion engine correspondingly, the first executing assembly and the second executing assembly are used for controlling work of the two sides of the V-type internalcombustion engine, and the switching box is used for switching control signals of the main ECU and the auxiliary ECU. The signal output end of the first detecting assembly is connected with the signalinput end of the main ECU, the signal output end of the second detecting assembly is connected with the signal input end of the auxiliary ECU, the control signal output end of the main ECU is connected with the control end of the first executing assembly and the control end of the second executing assembly through the switching box, the control signal output end of the auxiliary ECU is connectedwith the control end of the first executing assembly and the control end of the second executing assembly through the switching box, and the communication end of the main ECU is connected with the communication end of the auxiliary ECU. According to the engine electronic control redundant system, engine parameters of the two sides of the V-type internal combustion engine can be monitored, measuresare taken according to parameter abnormity occurring on the two sides, and stable operation of the engine is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of engine control, and more specifically, it relates to an engine electronic control control redundancy system. Background technique [0002] At present, V-type internal combustion engines generally use a set of electronically controlled fuel systems. The electronically controlled fuel system only monitors the cylinders on one side of the V-type internal combustion engine, and cannot monitor the operating parameters of the cylinders on the other side. This control method has the following problems: 1. The electronically controlled fuel system only monitors the engine parameters on one side, and adjusts itself according to the parameters of one side, such as alarm, correction, torque limit or shutdown, etc., and the monitoring side is normal and the other side is normal. Abnormalities cannot be diagnosed. This type of problem will cause the user to have a safety hazard when using the engine; 2. When the ECU fails,...

AI Technical Summary

Problems solved by technology

[0002] At present, V-type internal combustion engines generally use an electronically controlled fuel system, which only monitors the cylinders on one side of the V-type internal combustion engine, and cannot monitor the working parameters of the cylinders on the other side.

This control method has the following problems: 1. The electronically controlled fuel system only monitors the engine parameters on one side, and adjusts itself according to the parameters on one side, such as alarm, correction, torque limit or shutdown. Abnormalities cannot be diagnosed, and such problems will cause potential safety hazards when users use the engine; 2. When the ECU fails, it will be stopped immediately in an emergency, and the fault state cannot be restarted. Such problems have potential safety hazards and are prone to major failures
