[0050] Figure 1 A flow chart of a vehicle operation control method provided by an embodiment of the present invention is applicable to situations where the vehicle operation control needs to be considered in consideration of the battery health status. The method can be executed by the vehicle operation control device, such as Figure 1 As shown, the specific steps include:

[0051] Step 110: When the hybrid vehicle is traveling in the calibration area, the battery power of the hybrid vehicle when traveling in the current operating condition is determined according to the current operating condition and the global cost optimal curve of the vehicle battery.

[0052] The hybrid vehicle is a vehicle that travels in a specific area and has a small fluctuation in average daily mileage, for example, a vehicle that travels in a specific mining area, a specific steel plant, etc. The calibration area can be understood as a specific area where the hybrid vehicle travels. When the hybrid vehicle travels in the calibration area, the battery power and generator power of the hybrid vehicle under various operating conditions when the battery life cycle cost is the lowest can be determined according to an embodiment of the present invention.

[0053] The hybrid vehicle has a built-in maximum power that the battery can provide when the global cost of the vehicle battery is the lowest when the hybrid vehicle is traveling in the calibration area under various working conditions. The global cost of the vehicle battery may include the battery replacement cost, fuel consumption cost and electricity cost. Specifically, the working condition characteristic parameters of various working conditions and the maximum power that the battery can provide when the global cost of the battery is the lowest under various working conditions can be stored based on the global cost optimal curve of the vehicle battery.

[0054] Specifically, when the hybrid vehicle is running 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 determining that the hybrid vehicle is running in the calibration area, the current working condition of the hybrid vehicle can be determined, and then the battery power of the hybrid vehicle when running in the current working condition can be determined in the global cost optimal curve of the vehicle battery according to the current working condition.

[0055] In an embodiment of the present invention, when it is determined that a hybrid vehicle is traveling in a calibration area, the battery power of the hybrid vehicle when traveling in the current operating condition can be determined based on the current operating condition and the global cost optimal curve of the vehicle battery, and when the hybrid vehicle is traveling in the current operating condition based on the battery power, the global cost of the vehicle battery is the lowest.

[0056] Step 120: Determine the current required power according to the current required torque of the hybrid vehicle, and determine the engine power according to the current required power and the battery power.

[0057] The vehicle's required torque can be determined based on the pedal opening and gear information determined by the driver, the vehicle's driving status or the current operating conditions.

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

[0059] The battery power determined above can be used to determine the motor power. Specifically, the motor power can be determined based on 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, where 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] Furthermore, the difference between the current required power and the motor power can be determined as the engine power.

[0062] In the embodiment of the present invention, after the current required power of the hybrid vehicle is determined, the engine power is determined according to the current required power and the battery power, thereby allocating the power source to the hybrid vehicle.

[0063] Step 130: Control the battery of the hybrid vehicle to output power based on the battery power, and control the engine of the hybrid vehicle to output power based on the engine power.

[0064] 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 to supply power to the motor so that the motor provides 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 to provide a power source for the vehicle.

[0065] In the embodiment of the present invention, the power output of the vehicle battery is controlled by the battery power, and the power output of the engine is controlled by the engine power, so as to realize the control of the battery based on the battery power and then the control of the motor to provide a power source for the vehicle, and the control of the engine based on the engine power to provide a power source for the vehicle, thereby realizing the operation control of the vehicle.

[0066] The vehicle operation control method provided by an embodiment of the present invention includes: determining that a hybrid vehicle is traveling in a calibration area, and determining the battery power of the hybrid vehicle when traveling in the current operating condition according to the current operating condition and the global cost optimal curve of the vehicle battery; determining the current required power according to the current required torque of the hybrid vehicle, and determining the engine power according to the current required 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. In the above technical scheme, when the hybrid vehicle is traveling in the calibration area, the battery power of the hybrid vehicle when traveling in the current operating condition is determined according to the current operating condition and the global cost optimal curve of the vehicle battery. When the hybrid vehicle is traveling in the current operating condition based on the battery power, the global cost of the vehicle battery is the lowest. After the current required power is determined according to the current required torque of the hybrid vehicle, the engine power is determined according to the current required power and the motor power that can be converted by the battery power, so as to realize the power source distribution of the hybrid vehicle, control the power output of the vehicle battery through the battery power, and then control the power output of the motor, and control the power output of the engine through the engine power. Under the premise of considering the lowest global cost of the vehicle battery, dual power sources are provided to the vehicle based on the motor and the engine, so as to realize the operation control of the vehicle.

[0067] Figure 2 This is a flow chart of another vehicle operation control method provided by an embodiment of the present invention. This embodiment is specific based on the above embodiment. Figure 2 As shown, in this embodiment, the method may further include:

[0068] Step 210: determine the calibration area in which the hybrid vehicle travels, and determine the operating condition characteristic parameters of each operating condition in the calibration area.

[0069] Specifically, the calibration area where the hybrid vehicle is traveling can be determined according to the demand of the hybrid vehicle. For example, if the demand is for the transportation of steel products in a steel plant, the calibration area can be determined as the steel plant. Then, all operating conditions in the calibration area and the operating condition characteristic parameters of each operating condition can be determined. For example, the average speed and variance, the average pedal opening and variance, and the allowable power of each operating condition can be determined.

[0070] In the embodiment of the present invention, the calibration area in which the hybrid vehicle is traveling and the operating condition characteristic parameters of the hybrid vehicle when traveling in various operating conditions are determined.

[0071] Step 220: Determine a target battery power corresponding to each of the operating conditions according to a global battery cost when the hybrid vehicle is driven in each of the operating conditions based on a plurality of preset battery powers.

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

[0073] Determine the global battery cost of the hybrid vehicle when it is traveling in each of the operating conditions based on each of the preset battery powers; and 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 operating conditions, the global battery cost is lowest when the hybrid vehicle travels in the operating condition based on the target battery power.

[0075] Specifically, first, a plurality of preset battery powers can be determined according to the total battery power. For example, a preset number of preset battery powers can be determined between 100% V-20% V, where V represents the total battery power. Secondly, the global battery cost of the hybrid vehicle when it is traveling in each operating condition based on each preset battery power can be determined. Specifically, the battery loss, fuel consumption and electricity cost of the hybrid vehicle when it is traveling in each operating condition based on each preset battery power within a preset time period can be determined by experiment, and the global battery cost of the hybrid vehicle when it is traveling in each operating condition based on each preset battery power can be determined. Of course, it is necessary to ensure that the whole vehicle operates normally when the hybrid vehicle is traveling in each operating condition based on each preset battery power. Furthermore, the target battery power corresponding to each operating condition can be determined based on the 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, and the global battery cost of the hybrid vehicle is the lowest when it is traveling in the operating condition based on the target battery power corresponding to the operating condition.

[0076] In an embodiment of the present invention, within a preset time period, by conducting experiments on vehicles traveling in various operating conditions within a calibration area based on multiple predicted battery powers, the target battery power corresponding to each operating condition is determined.

[0077] Step 230: construct the global cost optimal curve according to the operating condition characteristic parameters of each operating condition and the target battery power.

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

[0079] Specifically, the operating condition 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 corresponding relationship between the operating condition characteristic parameters and the target battery power of the operating condition.

[0080] In the embodiment of the present invention, a global cost optimal curve is constructed according to the operating condition characteristic parameters of each operating condition and the corresponding target battery power.

[0081] Step 240: When the hybrid vehicle is traveling in the calibration area, the battery power of the hybrid vehicle when traveling in the current operating condition is determined according to the current operating condition and the global cost optimal curve of the vehicle battery.

[0082] In one embodiment, determining the battery power of the hybrid vehicle when traveling in the current operating condition according to the current operating condition and the global cost optimal curve of the vehicle battery includes:

[0083] An operating condition characteristic parameter of the current operating condition is determined, and the battery power is determined in the global cost optimal curve based on the operating condition characteristic parameter.

[0084] Specifically, when determining that the hybrid vehicle is traveling in the calibration area, the current operating condition can be determined first according to the current vehicle state of the hybrid vehicle, and secondly, the battery power corresponding to the current operating condition can be determined in the global cost optimal curve of the vehicle battery according to the operating condition characteristic parameters corresponding to the current operating condition, and the battery power is determined as the battery power when the hybrid vehicle is traveling in the current operating condition.

[0085] In an embodiment of the present invention, when it is determined that the hybrid vehicle is traveling in a calibration area, the battery power of the hybrid vehicle when traveling in the current operating condition is determined in the global cost optimal curve of the vehicle battery according to the current operating condition. When the hybrid vehicle is traveling in the current operating condition based on the battery power, the global cost of the vehicle battery is the lowest.

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

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

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

[0089] Specifically, the current required torque of the hybrid vehicle can be determined based on the pedal opening and gear information. In practical applications, the current required torque of the hybrid vehicle can also be determined based on the current working condition of the hybrid vehicle. Secondly, the current required power can be determined based on the current speed and current required torque of the hybrid vehicle. Specifically, Among them, P represents the current required power, T represents the current required torque, v represents the current speed, and r represents the wheel radius.

[0090] Of course, the motor power can also be determined based on the battery power. Specifically, W=NQ can be determined, where 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] Furthermore, the difference between the current required power and the motor power can be determined as the engine power.

[0092] In the embodiment of the present invention, after the current required power of the hybrid vehicle is determined, the engine power is determined according to the current required power and the battery power, thereby allocating the power source to the hybrid vehicle.

[0093] Step 260: Control the battery of the hybrid vehicle to output power based on the battery power, and control 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 then the motor can be controlled to output power to provide 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 to provide a power source for the vehicle.

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

[0096] The vehicle operation control method provided by the embodiment of the present invention includes: determining the calibration area in which the hybrid vehicle is traveling, and determining the operating condition characteristic parameters of each of the operating conditions in the calibration area; determining the target battery power corresponding to each of the operating conditions according to the global battery cost of the hybrid vehicle when traveling in each of the operating conditions based on multiple preset battery powers; constructing the global cost optimal curve according to the operating condition characteristic parameters of each of the operating conditions and the target battery power; when determining that the hybrid vehicle is traveling in the calibration area, determining the battery power of the hybrid vehicle when traveling in the current operating condition according to the current operating condition and the global cost optimal curve of the vehicle battery; determining the current required power according to the current required torque of the hybrid vehicle, and determining the engine power according to the current required 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 is traveling, determines the operating condition characteristic parameters of each operating condition in the calibration area, and within a preset time period, conducts experiments on vehicles traveling in each operating condition in the calibration area based on multiple predicted battery powers to determine the target battery power corresponding to each operating condition. When the hybrid vehicle is traveling in the operating condition based on the target battery power corresponding to the operating condition, the global battery cost is lowest. According to the operating condition characteristic parameters of each operating condition and the corresponding target battery power, the global cost optimal curve of the vehicle battery is constructed, and the construction of the global cost optimal curve of the vehicle battery is realized. When the hybrid vehicle is traveling in the calibration area, the global cost optimal curve of the vehicle battery is determined according to the current operating condition and the global cost optimal curve of the vehicle battery. The battery power of the hybrid vehicle when it is traveling in the current operating condition is determined. When the hybrid vehicle is traveling in the current operating condition based on the battery power, the global cost of the vehicle battery is the lowest. After determining the current required power according to the current required torque of the hybrid vehicle, the engine power is determined according to the current required power and the motor power that can be converted by the battery power, so as to realize the power source distribution of the hybrid vehicle, control the power output of the vehicle battery through the battery power, and then control the power output of the motor, and control the power output of the engine through the engine power. Under the premise of considering the lowest global cost of the vehicle battery, dual power sources are provided to the vehicle based on the motor and the engine, so as to realize the operation control of the vehicle.

[0097] Figure 3 This is a schematic diagram of the structure of a vehicle operation control device provided by an embodiment of the present invention, which can be applied to situations where the vehicle operation control needs to be considered in consideration of the battery health status. The device can be implemented by software and / or hardware and is generally integrated in the vehicle.

[0098] like Figure 3 As shown, the device comprises:

[0099] A determination module 310 is used to determine the battery power of the hybrid vehicle when the hybrid vehicle is traveling in the calibration area according to the current operating condition and the global cost optimal curve of the vehicle battery;

[0100] An execution module 320 is configured to determine a current required power according to a current required torque of the hybrid vehicle, and determine an engine power according to the current required power and the battery power;

[0101] The control module 330 is configured to control the battery of the hybrid vehicle to output power based on the battery power, and to control the engine of the hybrid vehicle to output power based on the engine power.

[0102] The vehicle operation control device provided in this embodiment determines that when a hybrid vehicle is traveling in a calibration area, the battery power of the hybrid vehicle when traveling in the current operating condition is determined according to the current operating condition and the global cost optimal curve of the vehicle battery; the current required power is determined according to the current required torque of the hybrid vehicle, and the engine power is determined according to the current required power and the battery power; 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.
