Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, the present invention provides a valve sticking simulation apparatus including:
the throttle valve signal simulator 1 is used for simulating and outputting different throttle valve signals to the control circuit, wherein the different throttle valve signals comprise a normal throttle valve signal and a stuck throttle valve signal.
And the control circuit 2 is used for determining and outputting different throttle signals to the ECU according to different judgments of the received control signals.
The control signal is derived from an electrical signal (e.g., a key signal, etc., which is selected according to the control logic of a different manufacturer) on the vehicle. The ECU judges whether to enter the diagnosis of the OBD throttle valve jamming according to the difference of the signals. This signal is also used as a control input to a signal simulation device for OBD throttle stuck diagnostics for synchronization with the diagnostic logic.
When the control circuit 2 receives the control signal, whether the engine is in a normal state or enters an OBD throttle valve clamping stagnation diagnosis state is judged according to the signal, and corresponding action is carried out to determine whether a normal throttle valve signal or a clamping stagnation throttle valve signal when the OBD throttle valve is clamped.
The throttle signal simulator 1 can accurately simulate signals of the throttle in various states.
The specific principle is shown in fig. 2, and includes:
the input module 3 is a manual input device and is used for outputting different signal adjusting instructions to the voltage adjusting circuit;
a signal source 4 for outputting a reference signal to the voltage regulating circuit, the reference signal being generally a voltage signal of a fixed magnitude;
the voltage regulating circuit 5 is used for regulating the reference signal according to different signal regulating instructions sent by the manual input module to obtain different throttle valve signals meeting the requirements and outputting the signals to the signal output module;
the signal output module 6 is used for outputting the throttle valve signal to the control circuit and the signal display module;
and the signal display module 7 is used for displaying the throttle valve signal output by the signal output module to observe whether the obtained electric signal meets the requirement.
A control method of the throttle valve clamping stagnation simulation equipment comprises the following steps:
A. a tester connects the equipment to an ECU system on the vehicle;
B. and setting the signal size of the throttle valve jamming according to the requirements of the test outline. The jamming was previously established by pushing the throttle through a hard object and the measured jamming signal was recorded. The output analog throttle valve signal is regulated on the equipment through a manual input module, and the voltage control circuit outputs the corresponding throttle valve signal according to the manual input signal. And in the adjusting process, whether the signal meets the requirement can be observed through the signal display module.
C. When the vehicle is running, the control circuit can monitor the change of the control signal on the vehicle at any time. Under normal conditions, namely when the control signal received by the control circuit is a high-level signal, the control circuit can output a normal throttle valve signal; when the ECU enters OBD throttle clamping diagnosis, the control signal changes (generally, the signal falling edge changes from high level to low level), the control circuit detects the change of the control signal and outputs the clamping throttle signal simulated by the throttle signal simulator to the ECU end, and at the moment, the OBD diagnosis completes corresponding diagnosis according to the simulated signal.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Those not described in detail in this specification are within the skill of the art.
