Description

Technical Field

[0001] This invention relates to the field of vehicle control manufacturing technology, and in particular, to an engine control method, device, medium, and electronic equipment. Background Technology

[0002] Currently, when the phase sensor or speed sensor loses a signal, the engine is usually shut down and the fuel supply is cut off in order to protect the engine.

[0003] However, the loss of signal from the phase sensor or speed sensor may be due to interference rather than an engine malfunction, and therefore can quickly return to normal within a short period of time. In this case, when the engine loses signal, it changes from the original fuel injection and ignition strategy to shutting down and cutting off fuel. After the signal returns to normal, that is, shortly after the shutdown and fuel cut-off, it resumes the original fuel injection and ignition strategy. During the above process, the engine changes frequently, causing the vehicle to jerk and affecting the driving experience. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0057] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0059] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0060] Figure 1 A schematic diagram of the speed sensor in an embodiment of this application is shown. Figure 1In the diagram, 1 represents a magnet, 2 represents a chip, and 3 represents a signal disk. For a better understanding of this embodiment, please refer to [link to relevant documentation]. Figure 1 The detection principles of the speed sensor and the phase sensor are explained below:

[0061] The speed sensor includes a chip and a magnet. A signal disk is positioned along the crankshaft axis and has circumferential signal teeth and slots. The signal teeth and slots are spaced apart, with the spacing between the teeth being the same. Two consecutive signal teeth are removed, resulting in a signal disk with 58 solid teeth and 2 empty teeth (the two removed signal teeth). The signal teeth and slots alternately pass through the speed sensor, changing the magnetic field strength. The chip senses the change in magnetic field and outputs high and low level signals. The phase sensor operates on the same principle as the speed sensor, except that it is positioned along the camshaft axis and has 3 solid teeth and 1 empty tooth. The camshaft and crankshaft work together to ensure the engine functions properly.

[0062] Figure 2 A flowchart of an engine control method according to an embodiment of this application is shown. See also: Figure 2 This application provides an engine control method, including at least S1 to S3, as detailed below:

[0063] In step S1, the vehicle speed detection signal and the vehicle phase detection signal are acquired.

[0064] Specifically, the vehicle speed detection signal can be obtained through a speed sensor, and the vehicle phase detection signal can be obtained through a phase sensor.

[0065] In step S2, if only one of the vehicle speed detection signal and the vehicle phase detection signal is determined to be abnormal, the original fuel injection ignition strategy is maintained within a preset time.

[0066] Specifically, if only one of the vehicle speed detection signal and the vehicle phase detection signal is judged to be abnormal while the other signal is normal, the engine will not be shut down and fuel cut-off will be performed within a preset time, but the original fuel injection and ignition strategy will be maintained.

[0067] For example, if the vehicle speed detection signal is abnormal but the vehicle phase detection signal is normal, the original fuel injection and ignition strategy will be maintained within a preset time, and the engine will not be shut down to cut off fuel.

[0068] In step S3, after a preset time, it is determined whether the signal abnormality has been recovered, and the oil supply is cut off or stopped based on the determination result.

[0069] Optionally, the step of determining whether the abnormal signal has been recovered, and controlling whether to shut down the machine and cut off the oil supply based on the determination result, includes:

[0070] If the signal abnormality is determined to have been resolved, the original fuel injection and ignition strategy shall be maintained.

[0071] If the signal is determined to be abnormal and not recovered, the engine will be shut down and the fuel supply cut off.

[0072] Specifically, "signal abnormality recovered" can be understood as the signal has returned to normal, and the original fuel injection and ignition strategy can be maintained. "signal abnormality not recovered" can be understood as the signal has not returned to normal, indicating that the vehicle has a malfunction and needs to be shut down and fuel cut off.

[0073] Optionally, if only one of the vehicle speed detection signal and the vehicle phase detection signal is determined to be abnormal, the original fuel injection ignition strategy is maintained for a preset time, including:

[0074] If the vehicle speed detection signal is determined to be abnormal, the vehicle speed detection signal is set to momentary abnormality, and the original fuel injection ignition strategy is maintained.

[0075] Specifically, when the vehicle speed detection signal is in a momentary abnormal state, the engine will not stop and the fuel will be cut off, but the original fuel injection and ignition strategy will be maintained.

[0076] Optionally, the vehicle speed detection signal is determined to be abnormal, including:

[0077] If any tooth tip of the speed sensor is not detected, the vehicle speed detection signal is judged to be abnormal.

[0078] Specifically, if the tip of any tooth of the speed sensor is not detected, it indicates that the speed sensor has lost a signal tooth, and is therefore judged as abnormal.

[0079] Optionally, if only one of the vehicle speed detection signal and the vehicle phase detection signal is determined to be abnormal, the original fuel injection ignition strategy is maintained for a preset time, including:

[0080] If the vehicle phase detection signal is determined to be abnormal, the vehicle phase detection signal is set to momentary abnormality, and the original fuel injection ignition strategy is maintained.

[0081] Optionally, the vehicle phase detection signal is determined to be abnormal, including:

[0082] If any tooth tip of the phase sensor is not detected, the vehicle phase detection signal is judged to be abnormal.

[0083] Specifically, if any tooth tip of the phase sensor is not detected, it indicates that the phase sensor has lost a signal tooth, and is therefore judged as abnormal.

[0084] Optionally, before acquiring the vehicle speed detection signal and the vehicle phase detection signal, the method further includes:

[0085] The preset time is obtained based on the engine speed.

[0086] Specifically, the preset time can be multiple engine cycles, such as 10 engine cycles. The engine cycle is the time it takes for the engine to rotate once, which can be obtained from the engine speed.

[0087] In addition, the preset time can be a fixed time, such as 100ms.

[0088] Optionally, it also includes:

[0089] If both the vehicle speed detection signal and the vehicle phase detection signal are determined to be abnormal, the engine will be shut down and the fuel supply will be cut off.

[0090] In this embodiment, when the vehicle speed detection signal is abnormal, it is determined whether the vehicle phase detection signal is abnormal. If the vehicle phase detection signal is normal, the vehicle speed detection signal is set to momentary abnormality, and the original fuel injection ignition strategy is maintained for a preset time, instead of directly shutting down the engine and cutting off fuel based on the abnormal vehicle speed detection signal. After the preset time, it is determined whether the vehicle speed detection signal has returned to normal. If the vehicle speed detection signal has not returned to normal, then the engine is shut down and fuel is cut off. If the vehicle speed detection signal returns to normal, it indicates that the abnormality of the vehicle speed detection signal is an occasional tooth loss, and the engine is not shut down and fuel is cut off, and the original fuel injection ignition strategy is maintained. Similarly, when the vehicle phase detection signal is abnormal, it is determined whether the vehicle speed detection signal is abnormal. If the vehicle speed detection signal is normal, the vehicle phase detection signal is set to momentary abnormality, and the original fuel injection ignition strategy is maintained for a preset time, instead of directly shutting down the engine and cutting off fuel based on the abnormal vehicle speed detection signal. If the vehicle phase detection signal is abnormal, the engine will be shut down and fuel cut off immediately. After a preset time, it will be determined whether the vehicle phase detection signal has returned to normal. If the vehicle phase detection signal has not returned to normal, the engine will be shut down and fuel cut off. If the vehicle phase detection signal returns to normal, it indicates that the abnormality of the vehicle phase detection signal is an occasional missing tooth, and the engine will not be shut down and fuel cut off, and the original fuel injection and ignition strategy will continue. By verifying the vehicle phase detection signal and the vehicle speed detection signal, if only one signal is abnormal, the engine will not be shut down and fuel cut off temporarily. Instead, it will be determined whether the abnormal signal can return to normal within a preset time. If it can return to normal, the engine will not be shut down and fuel cut off throughout the process. If it cannot return to normal, the engine will be shut down and fuel cut off will be performed. In this way, the engine will not be shut down and fuel cut off when the vehicle speed detection signal and the vehicle phase detection signal are occasionally missing teeth, thereby reducing the number of times the engine will shut down and fuel cut off and reducing vehicle jerking.
