The stable working state refers to that after the vehicle is detected to start, the ECU of the detected vehicle judges the working state of the vehicle, and after the vehicle is judged to be capable of running normally, the vehicle is determined to be in the stable working state.
In an embodiment of the present invention, the determining whether the detected vehicle is in a stable operating state includes:
monitoring a dew point signal sent by an Electronic Control Unit (ECU) of the detected vehicle in real time, wherein the dew point signal indicates that the detected vehicle can work normally;
and when the dew point signal sent by the ECU is monitored, determining that the detected vehicle is in a stable working state.
The sulfur content detection device and the ECU CAN be in data connection through a CAN bus. After the detected vehicle is electrified, the ECU automatically judges whether the detected vehicle enters a stable working state according to the critical value of the normal working of the detected vehicle, and the critical values of the normal working of different vehicles are different, so that a manufacturer is required to calibrate the detected vehicle before leaving a factory of the detected vehicle; when the ECU determines that the vehicle is detected to enter a stable working state, the dew point signal is used as a mark, and the sulfur content detection device is enabled to know that the vehicle is in the stable working state through the CAN bus.

Further, the sensed value of the SOX sensor has the fourier measurement system SOX value as the calibration reference value.
S130, determining the sulfur content of the diesel oil of the detected vehicle according to the sulfur content effective value.
The sulfur content of diesel oil and the representation sulfur oxide concentration obtained by the SOX sensor need to be subjected to data judgment and mapping, because the sensing value of the SOX sensor represents the sulfur oxide concentration in tail gas, and the sulfur content of diesel oil represents the liquid sulfur content.

But the oxygen sensor and the exhaust temperature sensor are state sensors. A is the upstream region of the DOC, B is the downstream region of the DOC and the downstream region of the DPF, and C is the downstream region of the DPF. The nitrogen-oxygen sensor 10, the sox sensor 11, and the exhaust temperature sensor 12 should be provided at the same time. The SOX sensor can be independently arranged at any position of the A, B, C area, and the temperature exhaust sensor and the SOX sensor can be arranged at the same position. The signals of the sensors CAN be sent out through a CAN bus.

For example, the period of time is maintained on the condition that the exhaust gas temperature change value Δt, the exhaust gas back pressure Δp, and the air-fuel ratio Δλ are each smaller than a certain threshold value. For example, when the exhaust gas temperature change value is less than 5 ℃, the air-fuel ratio Δλ is less than 0.4, the load percentage is not more than 50% and is maintained for 5 minutes, for example, the interval between the detection time points is half a minute, the difference between the sensing values of the sensors obtained at the 10 detection time points is within the above-mentioned exemplary values, and it is determined that the engine is in a stable operation state.

wherein S is i For the sulfur content of diesel oil, i represents the air-fuel ratio of i, x n Is the effective value of sulfur content, k n To correspond to x n Is a multiple of the factor, Σk n x n Is the combination of the effective value multiple of sulfur content and the power of n, n is more than or equal to 0, n is a positive integer, and b is an offset coefficient factor.
After the engine is in a stable working state, namely the data conversion condition is met, the sulfur content effective value of the SOX sensor is obtained, and the data conversion is carried out by the formula to obtain the sulfur content of diesel oil of the detected vehicle.

and determining the sulfur content of the diesel oil according to the air-fuel ratio, the sulfur content effective value, the multiple factor and the deviation factor through the formula.
Because the formula variables in the above formula are continuously changed, each formula variable which is currently applicable needs to be determined when the calculation is performed, the saved air-fuel ratio, the sulfur content effective value, the multiple factor and the deviation factor need to be acquired first and substituted into the above formula for calculation, so as to obtain a data conversion result.
In an embodiment of the present invention, the air-fuel ratio, the sulfur content effective value, the multiple factor, and the offset factor are stored in an offline storage medium in a MAP format.

FIG. 4 is a schematic diagram of a MAP format table for use in an embodiment of the invention, wherein formula variables are stored in the table, and each formula variable is obtained by querying the table during the process of performing data conversion by the formula.
Furthermore, in the embodiment of the present invention, the data conversion module may include a state machine for implementing the measurement step in the above embodiment. FIG. 5 is a schematic diagram of a state machine to which the present invention is applied, where the data conversion module enters state 1 after power-up initialization is completed; the state 1 reads MAP data, waits for entering a stable working condition state, and sets an active flag; the state 2 activates the data screening condition, if the screening condition is met, a trans mark is set, and the effective value sensed by the SOX sensor is output; otherwise, clearing the active mark and returning to the state 1; and the state 3 converts the effective value of the sensor data according to the MAP data, sets a complex flag if the MAP preset data is met, outputs the sulfur content value of diesel oil, otherwise clears a trans flag, and returns to the state 2.
