[0006] According to a first aspect of the present application, there is provided an engine torque control method, comprising: determining a first torque value and a second torque value of the vehicle's engine according to the vehicle's current speed, respectively, when the vehicle satisfies a preset speed condition; the preset speed condition is used to indicate that the vehicle's speed is greater than a preset threshold; the first torque value comprises a torque value required to maintain the current speed and the vehicle's charge when the vehicle's driving mode is a hybrid mode; the second torque value comprises a torque value required to maintain the current speed when the vehicle's driving mode is an oil-powered mode; the minimum value of the first torque value and the second torque value is determined as the output torque value, and the vehicle is controlled to be in the driving mode corresponding to the output torque value.

[0007] According to the above technical means, the present application can determine a first torque value and a second torque value of the vehicle's engine based on the vehicle's current speed, respectively, when the vehicle meets a preset speed condition; determine the minimum of the first and second torque values ​​as the output torque value, and control the vehicle to enter a driving mode corresponding to the output torque value. Thus, since the first and second torque values ​​can reflect the power of the vehicle's engine, by determining the minimum of the first and second torque values ​​as the output torque value and controlling the vehicle to enter the driving mode corresponding to the output torque value, it is possible to determine an economical driving mode when the vehicle is traveling at high speeds. Furthermore, since the first torque value can simultaneously maintain the vehicle's current speed and charge, it is also possible to maintain a stable charge in hybrid mode.

[0008] In one possible implementation, determining the first torque value includes: obtaining a current torque value at a current speed; determining a third torque value based on the current speed; the third torque value includes a torque value required to increase to maintain the current speed and charge of the vehicle when the vehicle's driving mode is a hybrid mode; and determining the sum of the third torque value and the current torque value as the first torque value.

[0012] In a possible implementation, the method further includes: if the speed of the vehicle continues to be greater than a preset threshold within a preset time period, determining that the vehicle meets a preset speed condition.

In this way, another method for determining whether the vehicle meets the preset speed condition is realized.

[0014] In a possible implementation, the method further includes: the speed of the vehicle is negatively correlated with the preset duration.

[0018] In a possible implementation, the second torque value further includes a torque value required to maintain the operation of the vehicle's on-board electrical appliances when the vehicle's driving mode is an oil-powered mode.

[0041] In order to enable ordinary people 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 accompanying drawings.

[0042] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0043] For ease of understanding, the engine torque control method provided in this application is described in detail below with reference to the accompanying drawings.

[0044] FIG1 is a flow chart of an engine torque control method according to an exemplary embodiment. As shown in FIG1 , the engine torque control method includes the following steps:

[0045] S101: When a vehicle meets a preset speed condition, the electronic device determines a first torque value and a second torque value of an engine of the vehicle according to a current speed of the vehicle.

[0046] Among them, the preset speed condition is used to indicate that the vehicle speed is greater than a preset threshold; the first torque value includes the torque value required to maintain the current speed and the vehicle charge when the vehicle's driving mode is a hybrid mode; the second torque value includes the torque value required to maintain the current speed when the vehicle's driving mode is a gasoline mode.

[0047] As a possible implementation, if the current speed of the vehicle is greater than a preset threshold, the electronic device determines that the vehicle meets the preset speed condition; if the current speed of the vehicle is less than or equal to the preset threshold, the electronic device determines that the vehicle does not meet the preset speed condition.

[0048] When the vehicle meets a preset speed condition and the vehicle's driving mode is hybrid, the electronic device obtains a current torque value at the current speed and determines a third torque value based on the current speed; then, the electronic device determines the sum of the third torque value and the current torque value as the first torque value of the vehicle's engine.

[0049] When the vehicle meets a preset speed condition and the driving mode of the vehicle is the oil-powered mode, the electronic device calculates the torque value required to maintain the current speed of the vehicle and determines the torque value as the second torque value.

[0050] As another possible implementation, when the vehicle meets a preset speed condition and the vehicle's driving mode is the oil-powered mode, the electronic device calculates the torque value required to maintain the vehicle's current speed and the operation of the vehicle's electrical appliances.

[0051] It should be noted that the third torque value includes the torque value required to increase in order to maintain the current speed and charge of the vehicle when the vehicle's driving mode is the hybrid mode.

[0052] S102 : The electronic device compares the first torque value and the second torque value to obtain the minimum value between the first torque value and the second torque value.

[0053] S103: The electronic device determines the minimum value between the first torque value and the second torque value as the output torque value.

[0054] S104 : The electronic device controls the vehicle to be in a driving mode corresponding to the output torque value.

[0055] Exemplarily, when the minimum value between the first torque value and the second torque value is the first torque value, the electronic device controls the vehicle to be in the hybrid mode.

[0056] When the minimum value between the first torque value and the second torque value is the second torque value, the electronic device controls the vehicle to be in the oil-powered mode.

[0057] It will be appreciated that the technical solution provided in the embodiments of the present application determines, when the vehicle satisfies a preset speed condition, a first torque value and a second torque value of the vehicle's engine based on the vehicle's current speed. The minimum of the first and second torque values ​​is then determined as the output torque value, and the vehicle is controlled to operate in a driving mode corresponding to the output torque value. Thus, since the first and second torque values ​​can reflect the power of the vehicle's engine, determining the minimum of the first and second torque values ​​as the output torque value and controlling the vehicle to operate in the driving mode corresponding to the output torque value can achieve an economical driving mode when the vehicle is traveling at high speeds. Furthermore, since the first torque value can simultaneously maintain the vehicle's current speed and charge, the vehicle's charge can be kept stable in hybrid mode.

[0058] In some embodiments, to determine the first torque value, as shown in FIG2 , the engine torque control method provided by the embodiment of the present application further includes the following steps:

[0059] S201: The electronic device obtains a current torque value at a current speed.

[0060] As a possible implementation manner, the electronic device obtains the current torque value of the engine at the current speed from the engine feedback signal of the vehicle.

[0061] S202: The electronic device determines a third torque value according to the current speed.

[0062] The third torque value includes a torque value required to increase in order to maintain the current speed and charge of the vehicle when the vehicle's driving mode is the hybrid mode.

[0063] As a possible implementation manner, the electronic device searches a preset speed-torque value correspondence table to obtain a third torque value corresponding to the current speed.

[0064] It should be noted that the torque values ​​in the preset speed and torque value correspondence table are torque values ​​that need to be increased to maintain the speed and charge of the vehicle, obtained through calibration.

[0065] S203: The electronic device determines the sum of the third torque value and the current torque value as the first torque value.

[0066] As a possible implementation manner, the electronic device calculates the sum of the third torque value and the current torque value, and determines the sum of the third torque value and the current torque value as the first torque value.

[0067] As can be understood, the technical solution provided in the embodiments of the present application obtains the current torque value at the current speed; determines a third torque value based on the current speed; and then determines the first torque value as the sum of the third torque value and the current torque value. Thus, because the third torque value includes the additional torque required to maintain the current speed and charge when the vehicle is in hybrid mode, a method for determining the first torque value is implemented based on the third torque value and the current torque value.

[0068] In some embodiments, in order for the vehicle to meet a preset speed condition, as shown in FIG3 , the engine torque control method provided in the embodiment of the present application further includes the following steps:

[0069] S301. The electronic device determines whether the speed of the vehicle is continuously greater than a preset threshold within a preset time period.

[0070] As a possible implementation manner, the electronic device calculates the duration during which the speed of the vehicle continues to be greater than a preset threshold.

[0071] If the time period during which the vehicle's speed is continuously greater than the preset threshold is greater than or equal to the preset time period, the electronic device determines that the vehicle's speed is continuously greater than the preset threshold within the preset time period; if the time period during which the vehicle's speed is continuously greater than the preset threshold is less than the preset threshold, the electronic device determines that the vehicle's speed does not meet the requirement of being continuously greater than the preset threshold within the preset time period.

[0072] S302: If the speed of the vehicle continues to be greater than a preset threshold within a preset time period, the electronic device determines that the vehicle meets a preset speed condition.

[0073] It should be noted that the speed of the vehicle is negatively correlated with the preset time.

[0074] It is understandable that by reducing the preset time when the vehicle's speed is high, the vehicle can meet the preset speed condition earlier, and the vehicle can be controlled to be in an economical driving mode earlier.

[0075] It is understood that the technical solution provided in the embodiments of the present application determines whether the vehicle's speed is continuously greater than a preset threshold value within a preset time period; if the vehicle's speed is continuously greater than the preset threshold value within the preset time period, then the vehicle is determined to have met the preset speed condition. In this way, another method for determining whether a vehicle has met the preset speed condition is implemented.

[0076] In some embodiments, as shown in FIG4 , in actual application, the engine torque control method provided by the embodiment of the present application further includes the following steps:

[0077] S401. The electronic device obtains the current speed of the vehicle.

[0078] S402: The electronic device determines whether the vehicle is at a permitted high speed based on a preset speed threshold.

[0079] As a possible implementation method, if the current speed of the vehicle is greater than a preset first speed threshold, the electronic device determines that the vehicle meets the high-speed permission and sets the high-speed permission state to 1; if the current speed of the vehicle is less than or equal to the preset second speed threshold, the electronic device determines that the vehicle does not meet the high-speed permission and sets the high-speed permission state to 0.

[0080] In actual application, the second speed threshold is preset as a preset hysteresis interval.

[0081] It should be noted that the preset first speed threshold can be set according to the maximum speed of the expressway, and is usually set to be lower than the maximum speed limit.

[0082] Exemplarily, the preset hysteresis interval is 10 kilometers per hour.

[0083] S403: If the vehicle meets the high-speed permission, the electronic device triggers the high-speed driving timer.

[0084] S404: If the high-speed driving timer has been triggered, the electronic device obtains the timing duration of the high-speed driving timer.

[0085] S405: The electronic device determines whether the timing duration is greater than a preset timing duration.

[0086] In actual application, if the timing duration is greater than the preset timing duration, the electronic device determines that the vehicle meets the torque increase and sets the torque increase state to 1; if the timing duration is less than or equal to the preset timing duration, the electronic device determines that the vehicle does not meet the torque increase and sets the torque increase state to 0.

[0087] S406: If the vehicle meets the torque increase requirement, the electronic device determines the engine torque increase value at the current speed of the vehicle.

[0088] It should be noted that the electronic device may determine the engine torque increase value at the current speed of the vehicle by referring to the implementation of S202 described above, which will not be repeated here.

[0089] The increase in engine torque is positively correlated with the speed of the vehicle.

[0090] S407: The electronic device determines the sum of the engine torque increase value and the current torque value of the engine as the total engine torque value.

[0091] S408: The electronic device performs slope control processing on the total engine torque value to obtain the engine target torque.

[0092] For example, as shown in FIG5 , FIG5 is a schematic diagram showing an engine torque limit value 501 , a current engine torque value 502 , an engine target torque 503 , and a vehicle speed.

[0093] When the vehicle speed is 90 kilometers per hour, 100 kilometers per hour, or 110 kilometers per hour, the engine target torque value 503 and the current engine torque value 502 are both less than the engine torque limit 501 .

[0094] When the vehicle speed is 120 kilometers per hour, the engine target torque value 503 is greater than the engine torque limit 501 , and the engine current torque value 502 is less than the engine torque limit 501 .

[0095] When the vehicle speed is 130 kilometers per hour, the engine target torque value 503 and the current engine torque value 502 are both greater than the engine torque limit 501 .

[0096] In actual application, the electronic device performs filtering processing on the total engine torque value to reduce the interference value in the total engine torque value.

[0097] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of method. In order to realize the above functions, the engine torque control device or electronic device includes hardware structures and / or software modules corresponding to the execution of each function. It should be easy for those skilled in the art to realize that, in combination with the units and algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software.
