Control strategy for processing signals of dual sensors of diesel engine

Abstract

A control strategy for processing signals of dual sensors of a diesel engine. The control strategy comprises: acquiring output signals of two sensors, and on the basis of the output signals, determining whether a hardware fault is present; if the output signal of the first sensor is normal and the output signal of the second sensor shows that the hardware fault is present, using the output signal of the first sensor as a target signal; and if the output signal of the second sensor is normal and the output signal of the first sensor shows that the hardware fault is present, using the output signal of the second sensor as the target signal. In this way, the engine still can normally operate when a fault is reported, thereby ensuring the safe operation of the engine, and improving the usage comfort of a user.
