Description

Technical Field

[0002] Externally plug-in hybrid electric vehicles (PHEVs) are currently gaining popularity among major automakers as a key technology for energy conservation and emission reduction. PHEVs combine the characteristics of both electric and gasoline vehicles, making their technology more challenging than that of traditional gasoline and pure electric vehicles.

[0003] There are many technical indicators for evaluating plug-in hybrid electric vehicles (PHEVs), but the most relevant to users is the cost of ownership. A simple way to calculate the cost of ownership is by looking at the driving range with a full charge and a full tank of gas. This is a key indicator of the user's perceived experience, and if there is a discrepancy between the company's claims and the user's actual experience, it often leads to user complaints.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] Currently, the industry generally uses real-world driving methods for testing, resulting in poor consistency and repeatability of measurement results, with deviations exceeding 5%, and no laboratory testing methods are available. Therefore, this application provides a method and apparatus for determining the driving range category of hybrid electric vehicles.

[0053] Step S101: Test the driving range of the hybrid vehicle in pure electric consumption state under different driving scenarios to obtain the first full-charge driving range test results under different driving scenarios.

[0054] In this embodiment, the ambient temperature, driving conditions, and driving style differ in different driving scenarios. Different driving scenarios can be pre-constructed to test the full-charge, full-fuel range of hybrid vehicles, thus obtaining the range under different driving scenarios.

[0055] The constructed driving scenarios include: normal temperature driving scenario, extreme high temperature driving scenario, low temperature driving scenario, constant speed driving scenario, and normal temperature aggressive driving scenario. The normal temperature driving scenario refers to: an ambient temperature set at 23±3℃, air conditioning off, driving under WLTC conditions in a loop, and driving speed controlled within ±2km / h of the WLTC curve. The extreme high temperature driving scenario refers to: an ambient temperature set at 38±3℃, solar radiation intensity at 850±45W / m², air conditioning set at 23℃ automatic mode, driving under WLTC conditions in a loop, and driving speed controlled within ±2km / h of the WLTC curve. The extreme low temperature driving scenario refers to: an ambient temperature set at -7±3℃, air conditioning set at 22℃ automatic mode, driving under WLTC conditions in a loop, and driving speed controlled within ±2km / h of the WLTC curve. In the WLTC driving cycle, the vehicle speed is controlled within ±2km / h of the WLTC curve. In the constant speed driving scenario, the ambient temperature and air conditioning settings are based on the constructed normal temperature, high temperature, and low temperature scenarios, and the driving conditions are tested at 140km / h, 120km / h, and 100km / h, with a speed tolerance of ±2km / h. In the aggressive driving scenario, the ambient temperature and air conditioning settings are based on the constructed normal temperature, high temperature, and low temperature scenarios, and the driving conditions are tested in a cycle under the US06 driving cycle, with the vehicle speed controlled within ±2km / h of the US06 curve.

[0056] In this embodiment of the application, the hybrid electric vehicle can be, for example, an externally rechargeable hybrid electric vehicle.

[0057] Depending on the scenario, tests were conducted on the driving range of hybrid vehicles in pure electric mode and the fuel consumption in battery-maintaining mode.

[0058] Test method for driving range under pure electric consumption: The vehicle starts with a full charge and drives continuously in a cycle until the engine starts, at which point the test ends. Record the vehicle's energy consumption Q1 (kWh) and driving distance S1 (km). Pure electric driving energy consumption EC (Wh / km). Calculation method: EC = Q1 / S1.

[0059] Step S102: Obtain the fuel consumption of the hybrid vehicle in the battery-holding mode under different driving scenarios, and obtain the first full-fuel range test results under different driving scenarios.

[0060] Range test in battery hold mode: The vehicle was driven continuously for three cycles starting from the state of charge (SOC) mode, and the fuel consumption was measured. The average fuel consumption FC (L / 100km) was calculated. Based on the fuel tank capacity V (L), the driving range S2 (km) was calculated. Calculation method: S2 = V / FC.

[0061] Step S103: Determine the range attenuation rate based on the first full-charge range test result and the first full-fuel range test result.

[0062] In this step, the first total mileage under full charge and full fuel conditions in different driving scenarios can be determined based on the first full charge range test results and the first full fuel range test results. Then, the range attenuation rate can be calculated based on the first total mileage. For the specific calculation method, please refer to the following embodiments.

[0063] Step S104: Determine the driving range evaluation category of the hybrid vehicle based on the numerical range of the driving range attenuation rate.

[0064] The driving range of hybrid vehicles with a full charge and full tank of fuel was obtained through testing in different scenarios. Based on the driving range with a full charge and full tank of fuel in a normal temperature driving scenario, the attenuation rate of the driving range with a full charge and full tank of fuel in other driving scenarios was calculated relative to the driving range with a full charge and full tank of fuel in a normal temperature driving scenario.

[0065] The correspondence between different attenuation rates and evaluations can be established in advance, as shown in Table 1 below:

[0066] Table 1

[0067]

[0068]

[0069] The product is rated as excellent, average, or poor based on its attenuation rate in various scenarios. Excellent indicates that the indicator is industry-leading, Good indicates that the indicator is competitive, Average indicates that the indicator is at the industry average level, and Poor indicates that the indicator is below the industry average level.

[0070] This application embodiment obtains the first fully charged range test results and the first fully fueled range test results under different driving scenarios. Based on the first fully charged range test results and the first fully fueled range test results, the range attenuation rate is determined. Then, the range evaluation category of the hybrid vehicle is determined according to the numerical range of the range attenuation rate. This realizes the construction of an evaluation of the range of hybrid vehicles in a fully charged and fully fueled state in the laboratory. Compared with the test results of real vehicle road tests, the consistency and repeatability are better, and the deviation of consistency and repeatability is greatly reduced.

[0071] In another embodiment of this application, step S103, based on the first full-charge range test result and the first full-fuel range test result, determines the range attenuation rate, including:

[0072] Step S201: Obtain the second full-charge range test result under normal temperature driving scenario by testing the range of the hybrid vehicle in pure electric consumption state.

[0073] In this embodiment of the application, the attenuation rate of other driving scenario test results relative to the normal temperature driving scenario can be evaluated based on the results of the normal temperature driving scenario range test.

[0074] The following is a test of the driving range under normal temperature driving conditions with a full charge and full fuel tank: The driving range test method under pure electric consumption conditions is as follows: The vehicle is fully charged to 100% SOC in an environment of 23±3℃; the vehicle is immersed in the environment at 23±3℃ for no less than 8 hours; the test begins in the laboratory, starting from a full charge, and the vehicle is continuously driven under WLTC cycle conditions until the engine starts, at which point the test ends. The results of the second full-charge driving range test under normal temperature driving conditions are recorded. These results include: the vehicle's energy consumption QN1 (kWh) and the driving range SN1 (km). The calculation method for pure electric driving energy consumption ECN (Wh / km) is: ECN = QN1 / SN1.

[0075] Step S202: Obtain the fuel consumption of the hybrid vehicle in the battery-holding mode under normal temperature driving scenario, and obtain the second full-fuel range test result under normal temperature driving scenario.

[0076] The driving range test under normal temperature driving conditions with a full charge and full tank of fuel is as follows: Driving range test in battery hold mode: The vehicle's SOC value was set in battery hold mode; the vehicle was submerged at 23±3℃ for at least 8 hours; driving began in the laboratory, continuously driving three WLTC cycles with an interval of less than 30 minutes between cycles. The fuel consumption FCNi (L / 100km) for each trip was measured, and the average fuel consumption FCN (L / 100km) of the three trips was calculated. Based on the fuel tank capacity V (L), the driving range SN2 (km) using the fuel was calculated. SN2 (km) is calculated as: SN2 = V / FCN. SN2 (km) is the result of the second full-tank driving range test.

[0077] Step S203: Determine the range attenuation rate based on the first full-charge range test result, the first full-fuel range test result, the second full-charge range test result, and the second full-fuel range test result.

[0078] In this step, the second total mileage under the full charge and full fuel conditions in the normal temperature driving scenario can be determined based on the second full charge range test results and the second full fuel range test results in the normal temperature driving scenario. Then, the range attenuation rate can be calculated based on the first total mileage (described in the aforementioned embodiment) and the second total mileage. For the specific calculation method, please refer to the embodiment below.

[0079] In another embodiment of this application, determining the range degradation rate based on the first full-charge range test result, the first full-fuel range test result, the second full-charge range test result, and the second full-fuel range test result includes:

[0080] Step S301: Calculate the first total mileage of the hybrid vehicle under fully charged and fully fueled conditions in different driving scenarios based on the first fully charged range test results and the first fully fueled range test results.

[0081] The first total mileage S (km) under the condition of a vehicle with a full charge and full fuel is calculated as follows: S = S1 + S2, where S1 is the test result of the first full charge range and S2 is the test result of the first full fuel range.

[0082] Step S302: Calculate the second total mileage of the hybrid vehicle under the condition of full charge and full fuel in normal temperature driving scenario based on the second full charge range test results and the second full fuel range test results.

[0083] The second total range SN (km) under the condition of a vehicle with a full charge and full fuel is calculated as follows: SN = SN1 + SN2, where SN1 is the second full charge range test result and SN2 is the second full fuel range test result.

[0084] Step S303: The ratio of the first total mileage to the second total mileage is determined as the range attenuation rate.

[0085] In this embodiment of the application, the range reduction rate = first total mileage / second total mileage.

The driving range SH2 (km) was calculated based on the fuel tank capacity V (L). Calculation method: SH2 = V / FCH.

[0089] 3) The total mileage SH (km) of the vehicle under the condition of full battery and full fuel is calculated as follows: SH = SH1 + SH2.
