Detailed Description
The relevant terminology of the present invention is explained first, as follows:
a throttle valve: a core part of an air inlet system of a gasoline engine and a natural gas engine mainly comprises a driving motor, a return spring, a valve body, a position sensor and the like, wherein a throttle valve applied to the diesel engine is similar to a throttle valve, and the difference is that the throttle valve is normally closed and the throttle valve is normally open.
Opening degree of a throttle valve: and converting the electric signal acquired by the throttle position sensor into an actual opening.
MAP: the two-dimensional array, input X, Y, gets the corresponding output Z.
An EEPROM: EE is an electrically erasable programmable read-only memory, a memory chip without data loss after power failure.
Minimum opening degree of throttle valve: the technical route has the defect of air inlet delay characteristic, for convenience of engine control, a minimum required opening degree of a throttle valve is set at different rotating speeds and is used as a feedforward for control, for example, when the engine is idling, the minimum opening degree of the throttle valve can bear the torque requirement of most idling working conditions, the engine is guaranteed not to be flameout due to responsiveness when the engine is idling, and the residual idling partial torque is adjusted through the closed-loop PID control of the rotating speed. When the type of the throttle valve is larger to a certain degree, even if the throttle valve is at the minimum opening position, the rotating speed of the engine at idle speed can be larger than the idle speed set value due to the fact that the air inflow is larger than that of a normal throttle valve;
the front-rear pressure ratio of the throttle valve: the pressure ratio is the ratio of the measured value of a pressure sensor behind the throttle valve to the measured value of a pressure sensor in front of the throttle valve, according to a throttling formula and a gas flow characteristic, after the pressure ratio is larger than 0.95, the throttle valve is close to full open, a waste gas valve of the supercharger starts to intervene for supercharging, and the variation of the flow rate of intake air is large when the pressure ratio before and after the throttle valve is small, so the engine working condition when the pressure ratio is smaller than or equal to 0.95 is selected in order to ensure the diagnosis accuracy, or the pressure ratio when the waste gas valve of the supercharger calibrated in software starts to intervene is selected.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for detecting a throttle valve mis-installation according to an embodiment of the present invention, where the method includes:
s11, judging whether the throttle valve misloading detection state is a first state when the ECU is electrified;
s12, if not, judging whether the system to be detected has throttle control failure;
s13, if not, judging whether the engine is in an idling state;
s14, if yes, judging whether the current throttle opening is equal to the minimum throttle opening or the engine speed is greater than the idle speed set value;
s15, if yes, determining that the throttle valve is in a first throttle valve misloading fault state;

and S21, when the throttle valve misloading detection state is a first state when the ECU is electrified, judging whether the service trigger state of the throttle valve replacement is a second state, and if so, judging whether the system to be detected has throttle valve control failure.

and S41, setting the wrong throttle valve installation detection state, and storing the wrong throttle valve installation detection state into a preset memory.
Schematically, in conjunction with fig. 4, the working principle of the present embodiment is explained as follows:
① to prevent fault misjudgment caused by throttle aging in use, the diagnosis of fault of throttle installation is executed only once, when the diagnosis is completed, the state is detected, set and stored in EE, and read after power up, if the state is equal to 1, repeated detection is not carried out.
② if the engine throttle is replaced after sale, the self-learning function of the throttle will be triggered by the service tool, at this time, the fault detection is triggered synchronously to prevent the fault when replacing the throttle;
③ obtains engine speed, idle state, throttle actual opening, actual intake air flow, throttle front-to-back pressure ratio, and system fault status light parameters.
④ before fault diagnosis, it is first judged whether there is fault related to throttle control in the system, such as self-learning fault of throttle, deviation fault of throttle control, fault of electrical appliances of throttle, fault of position sensor of throttle, pressure and flow rate, if there is no fault, the subsequent judgment is made.
⑤, judging whether the opening of the throttle valve is abnormal when idling and no-load, if the required opening of the throttle valve for maintaining the target idling is equal to the minimum opening and/or the engine speed is larger than the idling set value, judging that the throttle valve has a fault and the throttle valve type is larger.
⑥ to prevent misjudgment, selecting the engine working condition with the pressure ratio less than or equal to the standard quantity 1, wherein the standard quantity 1 can be reasonably calibrated according to the pressure ratio when the supercharger exhaust valve is controlled, and the standard quantity 1 is generally selected to be equal to 0.95.
⑦ when the pressure ratio meets the condition, judging whether the actual opening of the throttle valve under the current working condition is smaller than the preset opening of the throttle valve and the duration is T1, if the condition is met, the current throttle valve is proved to be larger than the normal throttle valve, and the fault that the throttle valve is mistakenly installed is reported that the model of the throttle valve is larger, wherein the preset opening of the throttle valve is obtained by checking MAP according to the engine speed and the actual intake air flow, and the time is T1 can be calibrated.
⑧, judging whether the actual opening of the throttle valve under the current working condition is larger than the preset opening of the throttle valve and the duration time is T2, if the conditions are met, the current throttle valve is proved to be smaller than the normal throttle valve, and the fault 2 that the throttle valve is mistakenly installed is reported, namely the type of the throttle valve is smaller, wherein the preset opening of the throttle valve is obtained by checking MAP according to the rotating speed of the engine and the actual intake air flow, and the time is T2 can be calibrated.
⑨ when the above steps are all detected, setting the 'wrong throttle valve installation detecting state' and storing it in EE after the ECU is powered down.
It should be noted that in this embodiment, the throttle valve misloading detection is performed only once when the engine leaves the factory, so as to prevent the misjudgment of the fault caused by the long-term use and aging of the throttle valve, and meanwhile, if the throttle valve is replaced during the market service, the service tool can trigger the throttle valve misloading fault detection during the self-learning process, so as to prevent the misloading of the market replacement throttle valve.
