The method can be executed by a vehicle operation control device, as shown in the figure, and specifically includes the following steps: Figure 1

[0051] Step 110, when the hybrid vehicle is driving in the calibration area, determining the battery power of the hybrid vehicle driving in the current working condition according to the current working condition and the global cost optimal curve of the vehicle battery.

[0052] The hybrid vehicle is a vehicle driving in a specific area and having little fluctuation in daily driving mileage, for example, a vehicle driving in a specific mine area or a specific steel plant. The calibration area can be understood as a specific area where the hybrid vehicle drives. When the hybrid vehicle drives in the calibration area, the battery power and the generator power of the hybrid vehicle driving in each working condition considering the lowest global cost of the vehicle battery can be determined according to the embodiments of the present application.

[0053] The hybrid vehicle is built-in with the maximum power provided by the battery considering the lowest global cost of the vehicle battery when the hybrid vehicle drives in various working conditions in the calibration area. The global cost of the vehicle battery can include the battery replacement cost, the fuel consumption cost and the electricity cost. Specifically, the working condition characteristic parameters of various working conditions and the maximum power provided by the battery considering the lowest global cost of the battery can be stored based on the global cost optimal curve of the vehicle battery.

[0054] Specifically, when the hybrid vehicle drives in various working conditions in the calibration area based on the corresponding battery power, the global cost of the battery can be ensured to be the lowest. Therefore, when the hybrid vehicle drives in the calibration area, the current working condition of the hybrid vehicle can be determined, and then the battery power of the hybrid vehicle driving in the current working condition can be determined according to the current working condition in the global cost optimal curve of the vehicle battery.

[0055] ​In the embodiment of the present application, when it is determined that the hybrid vehicle is running in the calibration area, the battery power of the hybrid vehicle running in the current working condition can be determined according to the current working condition and the global cost optimal curve of the vehicle battery, and the global cost of the vehicle battery is the lowest when the hybrid vehicle runs in the current working condition based on the battery power.

[0056] In step 120, the current demand power is determined according to the current demand torque of the hybrid vehicle, and the engine power is determined according to the current demand power and the battery power.

[0057] The demand torque of the vehicle can be determined according to the pedal opening degree and gear information determined by the driver, the running state of the vehicle or the current working condition.

[0058] Specifically, the current demand torque of the hybrid vehicle can be determined according to the acceleration and load of the hybrid vehicle first, and the current demand power can be determined according to the current speed and the current demand torque of the hybrid vehicle second. Specifically, the current angular velocity can be determined according to the current speed and the wheel radius first, and the current demand power can be determined according to the product of the current demand torque and the current angular velocity.

[0059] The battery power determined in the foregoing manner can be used to determine the motor power. Specifically, the motor power can be determined according to the conversion rate of the battery and the battery power, that is, the product of the battery power and the conversion rate can be determined as the motor power.

[0060] It can be determined that W=NQ, wherein W represents the motor power, N represents the conversion rate of the battery, the specific value of N is determined by the battery model, and Q represents the battery power.

[0061] Further, the difference between the current demand power and the motor power can be determined as the engine power.

[0062] In the embodiment of the present application, after the current demand power of the hybrid vehicle is determined, the engine power is determined according to the current demand power and the battery power, and the power source distribution of the hybrid vehicle is realized.

[0063] In step 130, the battery of the hybrid vehicle is controlled to output power based on the battery power, and the engine of the hybrid vehicle is controlled to output power based on the engine power.

[0064] Specifically, after the battery power of the hybrid vehicle is determined, the battery of the hybrid vehicle can be controlled to output power based on the battery power to supply power to the motor, so that the motor provides a power source for the vehicle. After the engine power of the hybrid vehicle is determined, the engine of the hybrid vehicle can be controlled to output power based on the engine power to provide a power source for the vehicle.

[0065] In the embodiment of the present application, the battery power is used to control the power output of the vehicle battery, and the engine power is used to control the power output of the engine, so as to control the motor to provide power source for the vehicle based on the battery power, control the engine to provide power source for the vehicle based on the engine power, and further control the running of the vehicle.

[0066] The running control method of the vehicle provided by the embodiment of the present application comprises: determining the battery power of a hybrid vehicle running in a calibration area according to a current working condition and a global cost optimal curve of a vehicle battery; determining a current demand power according to a current demand torque of the hybrid vehicle, and determining an engine power according to the current demand power and the battery power; controlling the battery of the hybrid vehicle to perform power output based on the battery power, and controlling the engine of the hybrid vehicle to perform power output based on the engine power. According to the above technical solution, when the hybrid vehicle runs in the calibration area, the battery power of the hybrid vehicle running in the current working condition is determined according to the current working condition and the global cost optimal curve of the vehicle battery. When the hybrid vehicle runs in the current working condition based on the battery power, the global cost of the vehicle battery is the lowest. After the current demand power is determined according to the current demand torque of the hybrid vehicle, the engine power is determined according to the motor power that can be converted by the current demand power and the battery power, so as to realize the power source distribution of the hybrid vehicle. The battery power is used to control the power output of the vehicle battery, and the engine power is used to control the power output of the engine, so as to control the motor to provide power source for the vehicle based on the battery power, control the engine to provide power source for the vehicle based on the engine power, and further control the running of the vehicle.

[0067] Figure 2 The flowchart of another running control method of a vehicle provided by the embodiment of the present application is based on the embodiment described above. As shown in the figure, Figure 2 the method can further comprise:

[0068] In step 210, the calibration area in which the hybrid vehicle runs is determined, and the working condition characteristic parameters of each working condition in the calibration area are determined.

[0069] Specifically, the calibration area in which the hybrid vehicle runs can be determined according to the demand of the hybrid vehicle, for example, the demand is to transport steel products of a steel plant, and at this time, the calibration area can be determined as the steel plant. Further, all working conditions in the calibration area and the working condition characteristic parameters of each working condition can be determined, for example, the average value and variance of the vehicle speed, the average value and variance of the pedal opening, the allowable power, etc. of each working condition can be determined.

[0070] In this embodiment of the invention, the calibration area in which the hybrid vehicle travels and the characteristic parameters of the hybrid vehicle under various operating conditions are determined.

[0071] Step 220: Determine the target battery power corresponding to each operating condition based on the global battery cost of the hybrid vehicle when it operates under each operating condition based on multiple preset battery power.

[0072] In one implementation, step 220 may specifically include:

[0073] Determine the global battery cost of the hybrid vehicle when it operates under each of the preset battery power conditions; determine the target battery power corresponding to each of the operating conditions based on a global optimization algorithm.

[0074] Among them, for each of the aforementioned operating conditions, the overall battery cost is lowest when the hybrid vehicle operates under the aforementioned operating condition based on the target battery power.

[0075] Specifically, firstly, multiple preset battery power values ​​can be determined based on the total battery power. For example, a preset number of preset battery power values ​​can be determined between 100% V and 20% V, where V represents the total battery power. Secondly, the global battery cost of the hybrid vehicle under various operating conditions based on each preset battery power value can be determined. Specifically, battery wear, fuel consumption, and electricity costs of the hybrid vehicle under various operating conditions based on each preset battery power value can be experimentally measured over a preset time period, and the global battery cost of the hybrid vehicle under various operating conditions based on each preset battery power value can be determined. Of course, it is necessary to ensure that the hybrid vehicle operates normally under various operating conditions based on each preset battery power value. Furthermore, the target battery power corresponding to each operating condition can be determined based on a global optimization algorithm. Specifically, for each operating condition, the preset battery power corresponding to the lowest battery cost can be determined as the target battery power corresponding to the operating condition. The global battery cost is lowest when the hybrid vehicle operates under the target battery power corresponding to the operating condition.

[0076] In this embodiment of the invention, within a preset time period, experiments are conducted on vehicles operating under various conditions within a calibrated area based on multiple predicted battery powers to determine the target battery power corresponding to each operating condition.

[0077] Step 230: Construct the global cost-optimal curve based on the operating condition characteristic parameters of each operating condition and the target battery power.

[0078] The cost-optimal curve is constructed based on the battery power corresponding to the lowest global battery cost when the hybrid vehicle is driving under various operating conditions within the calibrated area. The global battery cost includes battery replacement cost, fuel consumption cost, and electricity cost.

[0079] Specifically, the characteristic parameters of each operating condition can be used as independent variables, and the target battery power corresponding to each operating condition can be used as the dependent variable to construct a multi-dimensional global cost-optimal curve. The global cost-optimal curve can show the correspondence between the characteristic parameters of the operating condition and the target battery power.

[0080] In this embodiment of the invention, a globally optimal cost curve is constructed based on the operating condition characteristic parameters of each operating condition and the corresponding target battery power.

[0081] Step 240: When the hybrid vehicle is driving in the calibrated area, determine the battery power of the hybrid vehicle when it is driving in the current operating condition based on the current operating condition and the global cost-optimal curve of the vehicle battery.

[0082] In one implementation, determining the battery power of the hybrid vehicle when it is operating under the current conditions, based on the current operating conditions and the global cost-optimal curve of the vehicle battery, includes:

[0083] Determine the operating condition characteristic parameters of the current operating condition, and determine the battery power based on the operating condition characteristic parameters in the global cost-optimal curve.

[0084] Specifically, when determining that a hybrid vehicle is driving in a calibrated area, the current operating condition can first be determined based on the current vehicle status. Then, the battery power corresponding to the current operating condition can be determined in the global cost-optimal curve of the vehicle battery based on the operating condition characteristic parameters corresponding to the current operating condition. This battery power is then determined as the battery power of the hybrid vehicle when it is driving in the current operating condition.

[0085] In this embodiment of the invention, when the hybrid vehicle is driving in the calibrated area, the battery power of the hybrid vehicle under the current operating conditions is determined from the global cost-optimal curve of the vehicle battery. When the hybrid vehicle is driving under the current operating conditions based on this battery power, the global cost of the vehicle battery is the lowest.

[0086] Step 250: Determine the current required power based on the current required torque of the hybrid vehicle, and determine the engine power based on the current required power and the battery power.

[0087] In one implementation, step 250 may specifically include:

[0088] The current required torque is determined based on the current accelerator pedal opening of the hybrid vehicle; the current required power is determined based on the current speed of the hybrid vehicle and the current required torque; the motor power is determined based on the battery power; and the difference between the current required power and the motor power is determined as the engine power.

[0089] Specifically, firstly, the current demand torque of the hybrid vehicle can be determined according to the pedal opening degree and the gear information, and in actual application, the current demand torque of the hybrid vehicle can also be determined according to the current working condition of the hybrid vehicle. Secondly, the current demand power can be determined according to the current speed and the current demand torque of the hybrid vehicle, specifically, the current demand power can be determined as P=Tv / r Wherein, P represents the current demand power, T represents the current demand torque, v represents the current speed, and r represents the wheel radius.

[0090] Of course, the motor power can also be determined according to the battery power, specifically, the motor power can be determined as W=NQ, wherein W represents the motor power, N represents the conversion rate of the battery, the specific value of N is determined by the battery model, and Q represents the battery power.

[0091] Further, the difference between the current demand power and the motor power can be determined as the engine power.

[0092] In the embodiment of the present application, after determining the current demand power of the hybrid vehicle, the engine power is determined according to the current demand power and the battery power, and the power source distribution of the hybrid vehicle is realized.

[0093] Step 260, controlling the battery of the hybrid vehicle to output power based on the battery power, and controlling the engine of the hybrid vehicle to output power based on the engine power.

[0094] Specifically, after determining the battery power of the hybrid vehicle, the battery of the hybrid vehicle can be controlled to output power based on the battery power, and the motor can be controlled to output power, thereby providing a power source for the vehicle. After determining the engine power of the hybrid vehicle, the engine of the hybrid vehicle can be controlled to output power based on the engine power, thereby providing a power source for the vehicle.

[0095] In the embodiment of the present application, the battery of the vehicle is controlled to output power by the battery power, and the engine is controlled to output power by the engine power, thereby realizing the control of the battery based on the battery power and the control of the motor to provide a power source for the vehicle, and realizing the control of the engine based on the engine power and the control of the engine to provide a power source for the vehicle, thereby realizing the operation control of the vehicle.

[0096] The vehicle operation control method provided in this embodiment of the invention includes: determining the calibration area in which the hybrid vehicle is traveling, and determining the operating condition characteristic parameters of each operating condition within the calibration area; determining the target battery power corresponding to each operating condition based on the global battery cost of the hybrid vehicle traveling under each operating condition based on multiple preset battery power; constructing the global cost optimal curve based on the operating condition characteristic parameters of each operating condition and the target battery power; determining the battery power of the hybrid vehicle traveling under the current operating condition based on the current operating condition and the global cost optimal curve of the vehicle battery when the hybrid vehicle is traveling in the calibration area; determining the current demand power based on the current demand torque of the hybrid vehicle, and determining the engine power based on the current demand power and the battery power; controlling the battery of the hybrid vehicle to output power based on the battery power, and controlling the engine of the hybrid vehicle to output power based on the engine power. The above technical solution, after determining the calibration area where the hybrid vehicle will operate, determines the characteristic parameters of each operating condition within the calibration area. Within a preset time period, experiments are conducted on the vehicle operating under each operating condition within the calibration area based on multiple predicted battery powers. The target battery power corresponding to each operating condition is determined. When the hybrid vehicle operates under the target battery power corresponding to the operating condition, the global battery cost is minimized. Based on the characteristic parameters of each operating condition and the corresponding target battery power, a global cost-optimal curve for the vehicle battery is constructed. This construction of the global cost-optimal curve for the vehicle battery is achieved. When the hybrid vehicle is operating within the calibration area, the global cost-optimal curve for the vehicle battery is determined based on the current operating condition and the global cost-optimal curve for the vehicle battery. The system determines the battery power of the hybrid vehicle under the current operating conditions. When the hybrid vehicle operates under the current battery power, the overall cost of the vehicle battery is minimized. After determining the current required power based on the current required torque of the hybrid vehicle, the engine power is determined based on the current required power and the motor power that can be converted from the battery power. This achieves the allocation of power sources for the hybrid vehicle. The power output of the vehicle battery is controlled through the battery power, which in turn controls the power output of the motor. The power output of the engine is controlled through the engine power. Under the premise of minimizing the overall cost of the vehicle battery, the system achieves dual power sources for the vehicle based on the motor and engine, thereby realizing the operation control of the vehicle.
