DETAILED DESCRIPTION

[0057] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application.

[0058] When designing an extended-range hybrid vehicle, a suitable generator is usually matched to the engine according to its characteristic power, and the corresponding relationship between the generator power and the engine speed is established in advance. In actual application, the generator can generate electricity at the corresponding power at different engine speeds according to the pre-established corresponding relationship.

[0059] However, in actual applications, the operating conditions of the entire vehicle may change, such as the engine torque limit failure condition, which will cause the actual output power of the engine at each speed to change compared to the characteristic power of the engine. If at a certain engine speed, the preset generator power is greater than the actual output power of the engine, then if the preset power is used for power generation, the engine will stall, thereby affecting driving safety.

[0060] The power generation control method, device, equipment and readable storage medium provided in this application are intended to solve the above technical problems in the prior art.

[0061] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0062] Embodiment 1

[0063] Figure 1 A flow chart of a power generation control method provided in an embodiment of the present application, such as Figure 1 As shown, the power generation control method provided in this embodiment includes the following steps:

[0064] Step 101: Determine the current operating condition of the target vehicle.

[0065] Step 102: Obtain the current engine speed of the target vehicle, and obtain the current engine output power of the target vehicle according to the pre-calibrated corresponding relationship between the engine output power and the engine speed of the target vehicle under the working condition.

[0066] Step 103: Control the current generator power of the target vehicle to be no greater than the current engine output power of the target vehicle.

[0067] It should be noted that the execution subject of the power generation control method provided in this embodiment may be a power generation control device. In practical applications, the power generation control device may be implemented by a computer program, such as application software, a computer program, etc., or by a medium storing relevant computer programs, such as a USB flash drive, a CD, etc.; or, it may also be implemented by a physical device integrated or installed with relevant computer programs, such as a chip, etc.

[0068] In this embodiment, if the engine power generation is greater than the engine output power, the engine will be turned off, thus affecting driving safety. Therefore, in order to ensure driving safety, the current engine output power can be obtained according to the corresponding relationship between the engine output power and the engine speed under the current working condition, and the current generator power generation can be controlled so that it is not greater than the current engine output power.

[0069] Specifically, the power generation control device can first determine the current operating condition of the target vehicle. The specific determination method will be described in detail in Example 2 of the present application and will not be repeated here.

[0070] It should be noted that the target vehicle is an extended-range hybrid vehicle, which includes but is not limited to any one of a car, a bus or a mining car. Accordingly, different types of target vehicles have different types of operating conditions, including but not limited to normal driving operating conditions, engine torque limit failure conditions, etc. This embodiment does not limit this.

[0071] Next, in order to obtain the current engine output power of the target vehicle and control the generator power generation based on the engine output power, the power generation control device can obtain the current engine speed of the target vehicle. The specific acquisition method is not limited in this embodiment. According to the pre-calibrated correspondence between the engine output power and the engine speed of the target vehicle under this working condition, the current engine output power of the target vehicle is obtained, and the current generator power generation power of the target vehicle is controlled to be no greater than the current engine output power of the target vehicle.

[0072] In an optional embodiment, Figure 2 A flow chart of a power generation control method provided in an embodiment of the present application, such as Figure 2As shown, the power generation control method provided in this embodiment is based on the above-mentioned embodiment 1, and step 102 includes the following steps:

[0073] Step 201: Receive the current engine speed of the target vehicle sent by the electronic control unit of the target vehicle.

[0074] Step 202: Find a pre-calibrated engine output power curve of the target vehicle under the working condition; wherein the abscissa of the engine output power curve is the engine speed, and the ordinate is the engine output power.

[0075] Step 203: According to the engine output power curve, the engine output power corresponding to the current engine speed of the target vehicle is obtained as the current engine output power of the target vehicle.

[0076] In practical applications, in order to obtain the current engine output power of the target vehicle, the power generation control device may receive the current engine speed of the target vehicle sent by the electronic control unit of the target vehicle.

[0077] Specifically, the power generation control device can send an instruction to the electronic control unit of the target vehicle to obtain the current engine speed of the target vehicle. When the electronic control unit of the target vehicle receives the instruction, it can send the current engine speed of the target vehicle obtained by the sensor of the target vehicle to the power generation control device.

[0078] Next, the power generation control device can search for a pre-calibrated engine output power curve of the target vehicle under a working condition consistent with the current working condition, wherein the abscissa of the engine output power curve is the engine speed and the ordinate is the engine output power.

[0079] Specifically, the power generation control device can search for an engine speed that is consistent with the current engine speed of the target vehicle in the horizontal axis of the engine output power curve, and determine a point in the engine output power curve whose horizontal axis is the engine speed, and the vertical axis of the point is the engine output power corresponding to the current engine speed of the target vehicle.

[0080] For example, if the current operating condition of the target vehicle is an engine torque-limited fault condition and the current engine speed is 1100 rpm, the power generation control device can search for a pre-calibrated engine output power curve of the target vehicle under the engine torque-limited fault condition, and find 1100 rpm in the horizontal axis of the curve, and then determine a point with a horizontal axis of 1100 rpm in the engine output power curve, and the vertical axis of the point is the engine output power corresponding to the current engine speed of the target vehicle.

[0081] Finally, the power generation control device may use the engine output power corresponding to the current engine speed of the target vehicle obtained according to the engine output power curve as the current engine output power of the target vehicle.

[0082] The power generation control method provided in this embodiment determines the current working condition of the target vehicle, obtains the current engine speed of the target vehicle, and obtains the current engine output power of the target vehicle according to the pre-calibrated corresponding relationship between the engine output power and the engine speed of the target vehicle under the working condition, and controls the current generator power generation of the target vehicle to be no greater than the current engine output power of the target vehicle. That is to say, in the embodiment of the present application, the corresponding relationship between the engine output power and the engine speed of the target vehicle under various working conditions is pre-calibrated. In practical applications, after determining the current working condition of the target vehicle, the current engine output power can be obtained according to the current engine speed, and the current generator power generation can be controlled to be no greater than the current engine output power, thereby effectively avoiding the problem of engine stalling caused by using the preset power generation for power generation, thereby ensuring driving safety.

[0083] Embodiment 2

[0084] On the basis of the above-mentioned embodiment 1, in order to further illustrate the power generation control method of the present application, the target vehicle is a mining car, and step 101 includes: receiving the current lifting switch state and engine running state of the target vehicle sent by the electronic control unit of the target vehicle; determining the current operating condition of the target vehicle according to the lifting switch state and the engine running state; wherein the operating condition includes one of the following operating conditions: normal driving operating condition, lifting operating condition and engine torque limit fault condition.

[0085] In this embodiment, the target vehicle is a mine car, and the types of working conditions of the mine car include normal driving working conditions, lifting working conditions and engine torque limit fault conditions.

[0086] Accordingly, in order to determine the current working condition of the target vehicle, the power generation control device can receive the current lifting switch state and engine running state of the target vehicle sent by the electronic control unit of the target vehicle, and determine the current working condition of the target vehicle according to the lifting switch state and the engine running state. The current working condition can be one of a normal driving working condition, a lifting working condition and an engine torque limit fault working condition.

[0087] In one example, based on the above-mentioned embodiment 2, the current operating condition of the target vehicle is determined according to the lift switch state and the engine operating state, including: if the lift switch state is off and the engine operating state is normal, then the current operating condition of the target vehicle is determined to be a normal driving operating condition.

[0088] Correspondingly, in step 102, the current engine output power of the target vehicle is obtained based on the pre-calibrated correspondence between the engine output power and the engine speed of the target vehicle under the operating condition, including: searching for a pre-calibrated first engine output power curve of the target vehicle under the normal driving operating condition; wherein the horizontal coordinate of the first engine output power curve is the engine speed, and the vertical coordinate is the first engine output power; and according to the first engine output power curve, obtaining the first engine output power corresponding to the current engine speed of the target vehicle as the current first engine output power of the target vehicle.

[0089] Correspondingly, step 103 includes: controlling the current generator power of the target vehicle to be no greater than the current first output power of the engine of the target vehicle.

[0090] Figure 3 A schematic diagram of a first output power curve of an engine provided in an embodiment of the present application, such as Figure 3 As shown, the first engine output power curve is a pre-calibrated engine output power curve of a target vehicle under normal driving operating conditions, wherein the horizontal axis is the engine speed and the vertical axis is the first engine output power.

[0091] For example, in actual applications, if the current engine speed of the target vehicle is 1300 rpm, the power generation control device can obtain the first engine output power corresponding to the current engine speed of the target vehicle of 1300 rpm, that is, 330 kilowatts, based on the first engine output power curve, and use 330 kilowatts as the current first engine output power of the target vehicle. Next, the power generation control device can control the current generator power of the target vehicle to be no more than 330 kilowatts, thereby avoiding engine flameout and ensuring driving safety.

[0092] In another example, based on the above-mentioned embodiment 2, the current operating condition of the target vehicle is determined according to the lifting switch state and the engine operating state, and it also includes: if the lifting switch state is on and the engine operating state is normal, then the current operating condition of the target vehicle is determined to be a lifting operation condition.

[0093] Correspondingly, in step 102, the current engine output power of the target vehicle is obtained based on the pre-calibrated correspondence between the engine output power and the engine speed of the target vehicle under the operating condition, including: searching for a pre-calibrated second engine output power curve of the target vehicle under the lifting operation condition; wherein the horizontal coordinate of the second engine output power curve is the engine speed, and the vertical coordinate is the second engine output power; and according to the second engine output power curve, obtaining the second engine output power corresponding to the current engine speed of the target vehicle as the current second engine output power of the target vehicle.

[0094] Accordingly, step 103 includes: controlling the current generator power of the target vehicle to be no greater than the current second output power of the engine of the target vehicle.

[0095] Figure 4 A schematic diagram of a second output power curve of an engine provided in an embodiment of the present application, such as Figure 4 As shown, the second output power curve of the engine is a pre-calibrated engine output power curve of the target vehicle under a lifting operation condition, wherein the abscissa is the engine speed and the ordinate is the second output power of the engine.

[0096] For example, in actual applications, if the current engine speed of the target vehicle is 1300 rpm, the power generation control device can obtain the second engine output power corresponding to the current engine speed of the target vehicle of 1300 rpm, that is, 260 kilowatts, based on the second engine output power curve, and use 260 kilowatts as the current second engine output power of the target vehicle. Next, the power generation control device can control the current generator power of the target vehicle to be no more than 260 kilowatts, thereby avoiding engine flameout and ensuring driving safety.

[0097] In another example, based on the above-mentioned embodiment 2, the current operating condition of the target vehicle is determined according to the lift switch state and the engine operating state, and it also includes: if the lift switch state is off and the engine operating state is abnormal, then the current operating condition of the target vehicle is determined to be an engine torque limiting fault condition.

[0098] Correspondingly, in step 102, the current engine output power of the target vehicle is obtained based on the pre-calibrated correspondence between the engine output power and the engine speed of the target vehicle under the operating condition, including: searching for a pre-calibrated third engine output power curve of the target vehicle under the engine torque limiting fault condition; wherein the horizontal coordinate of the third engine output power curve is the engine speed, and the vertical coordinate is the third engine output power; and according to the third engine output power curve, obtaining the third engine output power corresponding to the current engine speed of the target vehicle as the current third engine output power of the target vehicle.

[0099] Correspondingly, step 103 includes: controlling the current generator power of the target vehicle to be no greater than the current third output power of the engine of the target vehicle.

[0100] Figure 5 A schematic diagram of a third output power curve of an engine provided in an embodiment of the present application, such as Figure 5 As shown, the third engine output power curve is a pre-calibrated engine output power curve of a target vehicle under an engine torque limit fault condition, wherein the abscissa is the engine speed and the ordinate is the third engine output power.

[0101] For example, in actual applications, if the current engine speed of the target vehicle is 1300 rpm, the power generation control device can obtain the second engine output power corresponding to the current engine speed of the target vehicle of 1300 rpm, that is, 160 kilowatts, according to the third output power curve of the engine, and use 160 kilowatts as the current third engine output power of the target vehicle. Next, the power generation control device can control the current generator power of the target vehicle to be no more than 160 kilowatts, thereby avoiding engine flameout and ensuring driving safety.

[0102] The power generation control method provided in this embodiment takes the mining car as the target vehicle and pre-calibrates the engine output power curve of the target vehicle under various operating conditions. In actual applications, after determining the current operating condition of the target vehicle, the current engine output power can be obtained according to the corresponding output power curve, and the current generator power generation power is controlled not to be greater than the current engine output power, thereby effectively avoiding engine stalling and ensuring driving safety.
