However, for accessories such as a generator, an air compressor, and a hydraulic pump, the engine cannot accurately obtain the working state of the accessories, which leads to inaccurate accessory torque values and further affects the accuracy of clutch control.

[0049] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings.

[0050] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0051] In the following, some of the terms in the embodiments of the present application are explained and described in order to facilitate understanding by those skilled in the art.

[0052] (1) AMT is a device that realizes automatic shifting of the entire shifting process by replacing manual operation to complete the separation and engagement of the clutch and the selection and shifting of the gearbox through the installation of an electronic control device without changing the main structure of the gearbox.

[0053] (2) Actual torque value, i.e. engine internal torque value, is the torque value of the piston driven by fuel combustion.

[0054] (3) Friction torque value is the torque value consumed by the engine to overcome friction.

[0055] (4) Accessory torque value is the torque value consumed by the accessories driven by the engine, which generally includes a fan, an air conditioning compressor, a generator, an air compressor and a hydraulic pump, etc.

[0056] At present, the demand for AMT for vehicles increases year by year, and users also have higher and higher requirements for shifting comfort. When a vehicle is matched with an AMT, the engine needs to accurately send the accessory torque value and calculate the output torque value of the clutch to ensure the accuracy of clutch control. However, for the generator, air compressor, hydraulic pump and other accessories, the engine cannot accurately obtain the working state of the accessories, which leads to inaccurate accessory torque value and further affects the accuracy of clutch control.

[0057] Therefore, the present application provides a method for adjusting engine accessory torque and related devices, which can accurately adjust the accessory torque value of the engine by using the pre-constructed correlation between the running state of the engine and the output torque, thereby ensuring the accuracy of clutch control.

[0058] After introducing the design idea of the embodiments of the present application, the application scenarios to which the technical solutions of the embodiments of the present application can be applied are briefly introduced as follows. It should be noted that the following application scenarios are only used to illustrate the embodiments of the present application but not to limit the embodiments of the present application. In actual implementation, the technical solutions provided by the embodiments of the present application can be flexibly applied according to actual needs.

[0059] Reference Figure 1 which is an application scenario diagram of the system for adjusting engine accessory torque provided by the embodiments of the present application. The application scenario includes an engine 101, an AMT 102, and other components 103 of a vehicle. The engine 101 performs information interaction with the AMT 102 and the other components 103 of the vehicle through a controller area network (CAN). For example, after receiving a signal that the vehicle is in neutral sent by an electronic control unit (ECU), the engine 101 sends an actual torque value, a friction torque value, and an accessory torque value to the ECU.

[0060] As shown in FIG. 1, Figure 2 the embodiments of the present application provide a flowchart of a method for adjusting engine accessory torque, including the following steps:

[0061] S201, the engine is powered on and runs;

[0062] S202, an initial value of the accessory torque based on the engine speed is set to zero;

[0063] S203, it is determined whether the engine is in a running state;

[0064] If yes, step S204 is performed, and if no, step S203 is continuously performed;

[0065] S204, it is determined whether the gearbox is in neutral;

[0066] If yes, step S205 is performed, and if no, step S203 is continuously performed; here, by ensuring that the gearbox is in neutral, it is ensured that there is no power output when the engine runs.

[0067] S205, it is determined whether the engine speed change rate meets a preset requirement;

[0068] If yes, step S206 is performed, and if no, step S203 is continuously performed; here, in order to reduce the influence of angular acceleration on the calculation of the torque value, by ensuring that the engine speed change rate meets the preset requirement, it is ensured that the engine is stably running in the current working condition.

[0069] S206, it is determined whether the running state of the engine is an idle state;

[0070] If yes, step S207 is executed, and if no, step S208 is executed; here, the engine operating state can be a low idle state or a high idle state.

[0071] S207, determining whether the engine operating time meets a preset time;

[0072] If yes, step S2012 is executed, and if no, step S203 is continuously executed; here, by the engine operating time meeting the preset time, the current working condition is ensured to be stably operated.

[0073] S208, determining whether the engine operating state is an external speed control state;

[0074] If yes, step S209 is executed, and if no, step S2010 is continuously executed;

[0075] S209, determining whether the speed difference meets a preset difference;

[0076] If yes, step S2012 is executed, and if no, step S203 is continuously executed; here, by the speed difference meeting the preset difference, the current working condition is ensured to be stably operated.

[0077] S2010, determining whether the engine operating state is a throttle pedal state;

[0078] If yes, step S2011 is executed, and if no, step S203 is continuously executed;

[0079] S2011, determining whether the throttle pedal opening degree change rate meets a preset requirement;

[0080] If yes, step S2012 is executed, and if no, step S203 is continuously executed; here, by the throttle pedal opening degree change rate meeting the preset requirement, the current working condition is ensured to be stably operated.

[0081] S2012, calculating the output torque value at the current time;

[0082] Optionally, based on the speed of the engine at the current time, the actual torque value, the friction torque value and the accessory torque value of the engine are determined, and then the difference between the actual torque value and the friction torque value and the accessory torque value of the engine is determined as the output torque value of the engine.

[0083] S2013, adjusting the accessory torque value of the engine based on the correlation between the engine operating state and the output torque value and the output torque value of the engine.

[0084] S2014, if the engine output torque value does not exist in the pre-constructed engine operating state and output torque value correlation, the first output torque value and the second output torque value of the preset difference value of the engine output torque value are determined through the pre-constructed engine operating state and output torque value correlation; the engine accessory torque value is adjusted by interpolating the first output torque value and the second output torque value;

[0085] S2015, the engine power-off operation ends.

[0086] For example, assume that the constructed correlation relationship is idle state-speed 1-output torque value 1-adjusted accessory torque value 1, idle state-speed 2-output torque value 2-adjusted accessory torque value 2, and external speed control state-speed 3-output torque value 3-adjusted accessory torque value 3. If the current output torque value is output torque value 1, the engine accessory torque value at the current time is adjusted by accessory torque value 1. If the current output torque value is greater than output torque value 1 and less than output torque value 2, the engine accessory torque value at the current time is adjusted by accessory torque value 1 and accessory torque value 2. This is only an example, and the application does not limit the specific adjustment method.

[0087] Optionally, the engine operating state and output torque value correlation can be constructed in the following way:

[0088] First, based on the sample operating state of the engine, the sample output torque value of the engine is determined, and then the accessory torque value of the engine under the sample operating state of the engine is adjusted so that the sample output torque value of the engine is zero. Finally, based on the sample operating state of the engine, the sample output torque value of the engine, and the adjusted accessory torque value of the engine, the engine operating state and output torque value correlation is constructed.

[0089] As shown in Figure 3 The embodiment of the application discloses a flowchart of a method for adjusting engine accessory torque, which comprises the following steps:

[0090] S301, based on the current operating state of the engine, the output torque value of the engine is determined;

[0091] S302, based on the pre-constructed engine operating state and output torque value correlation and the engine output torque value, the engine accessory torque value is adjusted.

[0093] The determining module 401 is configured to determine an output torque value of the engine based on a running state of the engine at a current time.

[0094] The adjusting module 402 is configured to adjust an accessory torque value of the engine based on a pre-constructed correlation between the running state of the engine and the output torque value and the output torque value of the engine.

[0097] determine the output torque value of the engine as a difference between the actual torque value and the friction torque value and the accessory torque value of the engine.

[0101] construct the correlation between the running state of the engine and the output torque value based on the sample running state of the engine, the sample output torque value of the engine and the adjusted accessory torque value of the engine.

[0102] In a possible design, the adjusting module 402 is specifically configured to:

[0103] if the output torque value of the engine does not exist in the pre-constructed correlation between the running state of the engine and the output torque value, determine a first output torque value and a second output torque value that are different from the output torque value of the engine by a preset difference through the pre-constructed correlation between the running state of the engine and the output torque value;

[0104] adjust the accessory torque value of the engine by performing interpolation calculation on the first output torque value and the second output torque value.

[0105] In a possible design, the running state of the engine is that the engine is in an idle state, or the running state of the engine is that the engine is in an external rotating speed control state, or the running state of the engine is that the engine is in a throttle pedal state.
