Description

Technical Field

[0001] This application relates to the field of engine technology, and in particular to a control method, device, electronic equipment and storage medium for a hybrid engine. Background Technology

[0002] Traditional vehicles can only start their engines using a starter motor. However, with the development of vehicle technology, hybrid technology has emerged. Vehicles using hybrid technology can save fuel and reduce emissions compared to traditional vehicles. Its biggest feature is that it can start the engine in multiple ways.

[0003] Hybrid technology enables vehicle operation through an electric motor, engine, or a combination of both. The engine offers multiple starting options. When a hybrid engine needs to be started, the Hydraulic Control Unit (HCU) selects the starting method. This is primarily based on information obtained from itself or the Electronic Control Unit (ECU), such as ambient temperature, coolant temperature, remaining battery charge, and power requirements. These conditions are designed to prevent engine damage or meet the driver's needs (e.g., vehicle speed, rapid acceleration). However, they don't consider whether other components involved in the starting process might affect the start-up, potentially leading to starting failures.

[0004] In conclusion, improving the engine start-up success rate is an urgent issue that needs to be addressed. Summary of the Invention

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of the technical solutions of this application, and not all embodiments. Based on the embodiments recorded in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the technical solutions of this application.

[0046] The following describes some of the concepts involved in the embodiments of this application.

[0047] Initial starting method: This indicates whether the engine can be started and by what method. It is determined by the electronic control unit after detecting faults in the starter motor and camshaft, as well as detecting whether there are other faults in the engine. In this application, the initial starting method mainly includes a first initial starting method, a second initial starting method, a third initial starting method, and a fourth initial starting method. The first initial starting method indicates that the engine cannot be started, the second initial starting method indicates that the engine can be started without restriction, the third initial starting method indicates that tow start is used, and the fourth initial starting method indicates that starter motor start is used.

[0048] Engine starting conditions: This includes the conditions required for different engine starting methods and the driver's driving needs.

[0049] Target start-up method: This characterizes whether the engine can start and in what way it can be started. It is determined by the hybrid power controller based on the initial start-up method and the engine start-up conditions.

[0050] Other faults: Faults that, apart from those caused by the engine's camshaft, can directly prevent the engine from running, such as rail pressure issues or throttle valve damage.

[0051] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application. Furthermore, the embodiments and features in the embodiments of this application can be combined with each other without conflict.

[0052] like Figure 1 The diagram shown is an application scenario illustration of an embodiment of this application. The application scenario illustration includes an electronic control unit 110, a hybrid power controller 120, an engine 130, and a starter 140; the engine 130 includes a camshaft 131.

[0053] It should be noted that the control method of the hybrid engine in each embodiment of this application can be executed by the electronic control unit 110. After the electronic control unit 110 is powered on, it will detect the equipment status of the starter 140 and the camshaft 131 respectively, and determine the corresponding initial start mode according to the detection result, and send it to the hybrid power controller 120. Then, the hybrid power controller 120 determines the target start mode based on the initial start mode and the engine start conditions, and controls whether the engine 130 starts and in what way it starts according to the target start mode.

[0054] The following describes the control method for a hybrid engine provided by an exemplary embodiment of this application, in conjunction with the application scenarios described above and with reference to the accompanying drawings. It should be noted that the above application scenarios are only shown to facilitate understanding of the spirit and principles of this application, and the embodiments of this application are not limited in any way in this respect.

[0055] See Figure 2 The diagram shown is a flowchart of a control method for a hybrid engine provided in this application. The specific implementation process of this method is as follows: S201-S202:

[0056] S201: After the electronic control unit is powered on, it detects the status of the starter motor and the engine camshaft respectively and obtains the corresponding detection results.

[0057] The solution provided in this application is mainly applied to hybrid engines, which can be diesel engines, gasoline engines, etc. Unlike traditional engines, hybrid engines can have multiple starting methods, such as starter motor starting, electric motor towing, and vehicle towing. Starter motor starting is achieved by the meshing of the starter motor gear with the engine flywheel gear, and the rotation of the starter motor drives the crankshaft of the engine to rotate; electric motor towing is achieved by the electric motor obtaining electrical energy through the battery system and starting to rotate to tow the engine; vehicle towing relies on the movement of the wheels to drive the engine to rotate.

[0058] When the car key is turned to the ignition position (or the start button is pressed, depending on the vehicle design), the electronic control unit (ECU) is powered on. At this time, the hybrid system is in pure electric mode, and the engine is in a waiting-to-start state. Afterwards, in addition to checking the status of the starter motor and engine camshaft, the ECU can also detect other engine faults and obtain the corresponding test results.

[0059] Other faults mainly include serious issues such as rail pressure and throttle body damage. This application does not specify a particular order for testing the starter motor, camshaft, and other faults; they can be tested simultaneously or sequentially according to a certain order.

[0060] For example, suppose a driver turns the key to a hybrid vehicle to the ignition position. After the electronic control unit (ECU) is powered on, it first checks for engine rail pressure or other faults, and then further checks the starter motor and engine camshaft. Let's assume the ECU detects no other engine faults, the starter motor is working properly, but the camshaft is faulty.

[0061] S202: The electronic control unit determines the initial start-up method that matches the detection result and sends the initial start-up method to the hybrid power controller, so that the hybrid power controller determines the target start-up method based on the initial start-up method and the engine start-up conditions, and controls the engine's operating state based on the target start-up method.

[0062] In the above, the electronic control unit will determine the corresponding starting strategy, i.e. the initial starting method, based on whether the starter motor is faulty, the camshaft is faulty, and whether there are other faults in the engine.

[0063] In one scenario, if other engine malfunctions are detected, the electronic control unit sends a first initial start mode to the hybrid power controller; the first initial start mode indicates that starting is not possible. In another scenario, if no other engine malfunctions are detected, the electronic control unit determines an initial start mode that matches the detection results of the starter and camshaft, and sends the initial start mode to the hybrid power controller.

[0064] In other words, regardless of the starter and camshaft test results, if other engine faults are detected, the electronic control unit (ECU) directly sends a first initial start mode to the hybrid power controller to inform it that the engine cannot start. If no other engine faults are detected, the initial start mode is determined based on the starter and camshaft test results. Therefore, the ECU can choose to prioritize detecting other engine faults; if so, it sends the first initial start mode, otherwise it tests the starter and camshaft. Alternatively, it can simultaneously test the starter, camshaft, and other engine faults before determining the test results; this application does not impose specific limitations. The following explanation will elaborate on the example of prioritizing the detection of other engine faults before testing the starter and camshaft.

[0065] In the above context, "other faults" refers to faults other than those caused by the engine's camshaft that directly prevent the engine from running, such as rail pressure issues or throttle body damage. The scope of these other faults can be preset and can be detected by the electronic control unit.

[0066] When there are no other faults in the engine, the electronic control unit determines the condition of the starter and the engine camshaft.

[0067] Case 1: If the starter motor and camshaft are not faulty, the electronic control unit determines the corresponding initial starting mode as the second initial starting mode and sends the second initial starting mode to the hybrid power controller; the second initial starting mode indicates that there is no limit to starting.

[0068] When the starter motor is functioning normally and without faults, the engine can be started by starting with the starter motor. When the camshaft is not faulty, the engine can be started by starting with the electric motor or by starting with the entire vehicle. Therefore, the electronic control unit can send a second initial starting mode to the hybrid power controller, indicating that the engine can be started by any starting mode and there are no restrictions on starting.

[0069] Scenario 2: If the test results indicate that the starter motor is faulty but the camshaft is not faulty, the electronic control unit determines the corresponding initial starting mode as the third initial starting mode and sends the third initial starting mode to the hybrid power controller; the third initial starting mode indicates that tow start is used.

[0070] The aforementioned towing start includes two methods: motor towing and vehicle towing. If the starter motor is detected to be overheating or has a short circuit or open circuit, but the camshaft is not faulty, it means that it is not suitable to start the vehicle with the starter motor at the moment. However, it can be started by motor towing or vehicle towing. Therefore, the electronic control unit can send a third initial start mode to the hybrid power controller, indicating that the starter motor start mode is prohibited, but the motor towing and vehicle towing start modes can be used.

[0071] The existing technologies do not inspect the starter motor, making it impossible to determine if it is overheating, short-circuited, or has an open circuit. If the starter motor overheats and the engine is still started using it, it could lead to starter motor burnout or other accidents. Therefore, this application checks the starter motor for these issues before starting the engine. If these issues are present, but the camshaft is normal, the electronic control unit sends a third initial starting method message to the hybrid power controller, informing it that starting with the starter motor is not recommended, but the engine can be started using either electric motor towing or vehicle towing.

[0072] Case 3: If the test results indicate that the starter motor is not faulty but the camshaft is faulty, then the corresponding initial starting mode is determined to be the fourth initial starting mode, and the fourth initial starting mode is sent to the hybrid power controller; the fourth initial starting mode indicates that the starter motor is used for starting.

[0073] During towing and starting, the camshaft and crankshaft movements need to be synchronized. If the camshaft malfunctions, the electronic control unit (ECU) cannot determine the synchronization status and will therefore stop fuel injection to prevent the engine from continuing to run and causing further damage. In other words, when the ECU detects a camshaft malfunction, it indicates that starting using either the electric motor or the entire vehicle is not suitable. However, if the starter motor is detected to be functioning normally, and therefore can be used for starting, the ECU can send a fourth initial starting mode message to the hybrid power controller, indicating that towing and starting is prohibited and starting with the starter motor is recommended.

[0074] The existing technology does not inspect the engine camshaft, thus making it impossible to determine if the camshaft is faulty. If the camshaft is faulty and the engine is still started using a tow start method, the electronic control unit (ECU) cannot determine the synchronization status, resulting in fuel injection failure and engine start-up failure. Therefore, this application checks for the aforementioned camshaft problem before engine start. If the problem exists, but the starter motor is functioning normally, the ECU sends a fourth initial start method message to the hybrid power controller, informing it that tow start is not recommended and that the engine should be started using the starter motor instead.

[0075] Case 4: If the test results indicate that the starter motor and camshaft have failed, the corresponding initial starting mode is determined to be the first initial starting mode, and the first initial starting mode is sent to the hybrid power controller; the first initial starting mode indicates that the starter cannot be started.

[0076] When both the starter and camshaft fail, it means that neither starting with the starter nor starting with the tow engine is currently available. In this case, the electronic control unit can send the first initial start mode to the hybrid power controller, indicating that the engine cannot start and run.

[0077] In the above, the first initial start method, the second initial start method, the third initial start method and the fourth initial start method can be sent to the hybrid power controller in the form of messages, etc., and this application does not make specific limitations.

[0078] Following the assumption in S201, the electronic control unit detects that there are no other faults in the engine and the starter is functioning normally, but there is a fault in the camshaft. Therefore, the electronic control unit sends a fourth initial start mode to the hybrid engine. This allows the hybrid power controller to determine the target start mode based on the initial start mode and the engine start conditions, and to control the engine's operating state based on the target start mode.

[0079] The above process has been explained primarily using the electronic control unit. Next, we will explain the control method of the hybrid engine, focusing on the hybrid power controller. Figure 3 The diagram shown is a flowchart of another control method for a hybrid engine provided in this application. The specific implementation process of this method is as follows: S301-S302:

[0080] S301: The hybrid power controller receives the initial start-up mode sent by the electronic control unit.

[0081] In the above, the initial starting method is determined based on the detection results; the detection results are obtained by the electronic control unit detecting the respective equipment status of the starter and the engine camshaft. The initial starting method may be a first initial starting method, a second initial starting method, a third initial starting method, or a fourth initial starting method.

[0082] Following the assumption in S202, the hybrid power controller receives the fourth initial start mode sent by the electronic control unit.

[0083] S302: The hybrid power controller determines the target start-up mode based on the initial start-up mode and engine start-up conditions, and controls the engine's operating state based on the target start-up mode.

[0084] After receiving the initial start method, the hybrid power controller will first determine whether there is a need to start the engine before determining the target start method based on the initial start method and engine start conditions. If so, it will proceed with the process of determining the target start method.

[0085] Vehicles using hybrid technology can operate not only using the engine, but also solely using the electric motor, or a combination of both. If the vehicle can be started and started using only the electric motor, the engine does not need to be started. Alternatively, even if the driver presses the start button simply to turn on the radio, the engine also does not need to run.

[0086] If it is determined that the engine needs to be started, the hybrid power controller will combine the initial start method with the engine start conditions to select the final start method, which is the target start method mentioned above.

[0087] The hybrid power controller can determine the appropriate starting method based on the engine starting conditions. These conditions include the driver's driving needs and the different conditions required for different engine starting methods. For example, if the driver needs the vehicle to start quickly in a short time, the starter motor will be selected; another example is the electric motor-driven starting method, which requires that the ambient temperature and engine coolant temperature not be too low.

[0088] In addition, information such as engine coolant temperature, airflow, and battery charge can be acquired and compared with engine starting conditions to determine the appropriate starting method. This application does not impose specific limitations on this. The methods of acquiring information differ; some information can be directly detected by the hybrid power controller, while other information needs to be detected by the electronic control unit and sent to the hybrid power controller.

[0089] Finally, the hybrid power controller combines the initial starting method with the starting method determined by the hybrid power controller based on the engine starting conditions to obtain the target starting method. If there is overlap between the initial starting method and the starting method determined based on the engine starting conditions, the engine is started according to the overlapping starting method; for example, if the initial starting method is the second starting method (i.e., no starting restrictions), and the starting method determined based on the engine starting conditions is electric motor towing, then the hybrid power controller uses electric motor towing to start the engine; if the initial starting method is the fourth initial starting method (i.e., starter motor starting), and the starting method determined based on the engine starting conditions is also starter motor starting, then the hybrid power controller uses starter motor starting to start the engine.

[0090] When there is no overlap between the initial start method and the start method determined based on the engine start conditions, the hybrid power controller can either abandon engine start, i.e., not start the engine; or it can force the engine to start based on either the initial start method or the start method determined based on the engine start conditions, depending on the actual situation.

[0091] Furthermore, during vehicle operation, the vehicle operating mode can be adjusted according to the method proposed in this application, combined with the remaining battery charge percentage (State of Charge, SOC). For example, if the vehicle is currently in pure electric mode, that is, it relies entirely on the electric motor for operation, but the remaining battery charge gradually decreases and the engine needs to be started, the target starting method can be determined according to the above method, that is, how to start the engine.

[0092] Following the assumption in S301, after the hybrid power controller receives the fourth initial start method sent by the electronic control unit and confirms that the engine needs to be started, assuming that the start method determined according to the engine start conditions is also to start by the starter motor, the hybrid power controller starts the engine by starting the starter motor.

[0093] Based on the above process, such as Figure 4 The diagram shown is an interaction timing diagram of a control method for a hybrid engine provided in an embodiment of this application. The specific process is as follows:

[0094] After power-on, the electronic control unit (ECU) begins its checks, while the engine is in a waiting-to-start state. The ECU first checks for faults such as rail pressure. If any are found, the ECU sends a first initial start mode to the hybrid power controller, indicating that the engine cannot start. Otherwise, the ECU further checks for overheating in the starter motor. If the starter motor is overheating, the ECU checks for a fault in the camshaft. If the camshaft is also faulty, the ECU sends a first initial start mode to the hybrid power controller. If the camshaft is not faulty, the ECU sends a third initial start mode to the hybrid power controller; the third initial start mode indicates whether towing is done by electric motor or the entire vehicle.

[0095] If the starter motor does not overheat, the electronic control unit also needs to check if the camshaft is faulty. If the camshaft is faulty, the electronic control unit sends a fourth initial start mode to the hybrid power controller, which indicates that the starter motor is used for starting. If the camshaft is not faulty, the electronic control unit sends a second initial start mode to the hybrid power controller, which indicates that there are no restrictions on starting.

[0096] After receiving the initial start method, the hybrid power controller first needs to determine whether there is a need to start the engine. If so, it compares the engine start conditions with information such as the driver's driving needs, the current ambient temperature, engine water temperature, coolant temperature, and airflow to determine the appropriate start method. For example, when the driver needs to start the engine quickly, a start method with high torque and high power is required. Therefore, the hybrid power controller will choose to use a starter motor to start the engine, which can quickly turn the engine to the appropriate position in a short time.

[0097] It should be noted that the methods of obtaining the information mentioned above differ. Some information can be directly detected by the hybrid power controller, while other information needs to be detected by the electronic control unit and sent to the hybrid power controller.

[0098] Finally, the hybrid power controller combines the initial start-up method with the start-up method determined based on the engine start-up conditions to select the final target start-up method.

[0099] The order in which the starter motor, camshaft, and other engine faults are tested can be changed or performed simultaneously, and this application does not impose any restrictions on this.

[0100] Based on the same inventive concept, embodiments of this application also provide a control device for a hybrid engine. For example... Figure 5 The diagram shown is a structural schematic of the control device for a hybrid engine, which may include:

[0112] Optionally, the determining unit 502 is specifically used for:

[0118] The determining unit 602 is used to determine the target starting mode based on the initial starting mode and engine starting conditions, and to control the engine's operating state based on the target starting mode.
