Detailed ways

The present application will be described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all the structures related to the present application.

Example 1

FIG. 1 is a flowchart of a method for calculating energy consumption of a hybrid electric vehicle according to Embodiment 1 of the present application. This embodiment is applicable to the case of calculating the energy consumption of a plug-in hybrid electric vehicle, and the method can be executed by a device for calculating the energy consumption of a hybrid electric vehicle, which can be implemented by hardware and/or software, and the method includes the following steps .

Step 110: Calculate the cost of engine fuel consumption according to the engine fuel consumption and the local fuel price under the preset vehicle use state.

The preset vehicle usage state can be a vehicle usage scenario in which the hybrid vehicle consumes both fuel and battery power. During a driving cycle, the vehicle consumes both fuel and battery power, and can be used for fuel and battery power in some stages of the driving cycle. Power is consumed at the same time. The fuel consumption of the engine can be obtained by accumulating the fuel consumption of the car in this driving cycle according to the instantaneous fuel consumption of the engine. The local oil price can be the average oil price of the accumulated fuel of the car, and the average oil price can be stored in the vehicle control unit (Vehicle Control Unit, VCU) locally or stored in the cloud. When the energy consumption cost needs to be calculated, the average oil price stored in the VCU is obtained from the cloud. operation, and then provide the calculation result to the vehicle end.

Step 120: Calculate the cost of battery power consumption according to the power consumption of the battery, the local electricity price, the charging amount of the hybrid vehicle to the battery, and the charging cost of the hybrid vehicle.

In the process of using a hybrid vehicle, the power of the battery not only comes from external charging, but also comes from the charging of the vehicle in use. For example, the engine drives the generator to charge the battery, and the on-board energy recovery system converts the kinetic energy into electrical energy as Charging batteries. Then, the cost consumed when the engine drives the generator to charge the battery is the charging cost of the self-vehicle (hybrid electric vehicle). The charging of the battery by the self-vehicle will make the local electricity price change dynamically. Then, the local electricity price is dynamically adjusted according to the charging amount of the self-vehicle to the battery and the charging cost of the self-vehicle, and then the cost of the battery consumption is calculated according to the battery consumption. The local electricity price can be the average electricity price of the cumulative charging of the car, which is a static electricity price. The average electricity price can be stored locally in the vehicle VCU, or stored in the cloud. When the energy consumption fee needs to be calculated, the average electricity price stored in the VCU local is obtained from the cloud. , the VCU performs energy consumption cost calculation and fuel-electricity cost ratio calculation, or the cloud can perform corresponding calculation operations, and then provide the calculation results to the vehicle end.

Step 130: Calculate the ratio of energy consumption cost and oil and electricity cost according to the cost of engine fuel consumption and the cost of battery power consumption.

According to the cost of the overall engine fuel consumption and the cost of battery power consumption in the driving cycle, the energy consumption cost of the vehicle for 100 kilometers can be calculated, and the ratio of the cost of engine fuel consumption and the cost of battery power consumption can be calculated to obtain the fuel and electricity cost ratio . In this way, users can intuitively understand the energy consumption costs in the process of using the car. The calculated energy consumption cost and fuel and electricity cost ratio can be displayed to the user through the vehicle's dashboard and other devices, and can also be sent to the cloud, which is forwarded to the user's terminal, such as the user's mobile phone.

Optionally, before calculating the cost of engine fuel consumption according to the engine fuel consumption and the local oil price, it also includes: if the hybrid vehicle is refueling, calculate the fuel price after fueling according to the fuel volume, fuel price, remaining fuel volume and local fuel price, and use The local oil price is updated to the oil price after refueling.

When the vehicle is refueling, the oil price after refueling is calculated according to the refueling amount and oil price, the original remaining oil amount of the vehicle and the local oil price in the VCU. A gas station or a refueling application (Application, APP) sends the vehicle's refueling information (oil price, fuel quantity) to the VCU through the cloud or Bluetooth. If the vehicle is powered off when the vehicle is refueling, the refueling information is temporarily stored in the VCU. The cloud or mobile phone, after the vehicle is powered on, sends the refueling information to the VCU, or the vehicle has a refueling wake-up mode, and directly sends the refueling information to the VCU after the refueling is completed.

For example, Pp_new=(Lp_add*Pp_add+Lp_old*Pp_old)/(Lp_add+Lp_old); unit: Yuan/L, among which, Pp_new: oil price after refueling; Lp_add: oil amount for refueling; Pp_add: oil price for refueling; Lp_old: vehicle Pp_old: The original local oil price of the vehicle calculated by the VCU. After the vehicle is refueled, the Pp_old stored in the VCU is updated to Pp_new, that is, Pp_old=Pp_new.

Optionally, before calculating the cost of battery power consumption according to the battery power consumption, the local electricity price, the charging amount of the hybrid vehicle and the charging fee of the hybrid vehicle, it also includes: if the hybrid vehicle is charged, according to the charging amount. , charging electricity price, remaining electricity and local electricity price, calculate the electricity price after charging, and update the local electricity price to the electricity price after charging.

When the vehicle is charging, the electricity price after charging is calculated according to the charging amount and the charging electricity price, the original remaining electricity of the vehicle and the local electricity price in the VCU. The charging station or charging APP sends the charging information (electricity, electricity price) of the vehicle to the VCU through the cloud or Bluetooth. Since the vehicle VCU is in the wake-up state when the vehicle is generally charged, the VCU can directly receive the charging information when the charging is completed. .

For example, Pe_new_s=(Le_add*Pe_add+Le_old*Pe_old)/(Le_add+Le_old); unit: yuan/kWh, among which, Pe_new_s: updated local electricity price (electricity price after charging); Le_add: electricity charged, unit: kWh; Pe_add: the electricity price for charging; Le_old: the remaining electricity of the vehicle, unit: kWh; Pe_old: the original electricity price of the vehicle calculated by the VCU. After the vehicle is fully charged, Pe_old stored in the VCU is updated to Pe_new_s, that is, Pe_old=Pe_new_s.

The technical solution of this embodiment directly reflects the energy consumption cost of the vehicle through the engine oil consumption and battery power consumption, solves the problem that the user cannot intuitively know the energy consumption cost of the vehicle, and realizes the intuitive understanding of the two energy sources of the hybrid vehicle. The energy consumption cost situation, prompting the user to drive the vehicle in a more energy-efficient manner, improves the effect of the environmental friendliness of the hybrid vehicle.
