Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and more specifically, to a range-extended charging control method, apparatus, computer-readable storage medium, and range-extended vehicle. Background Technology

[0002] With the rapid development of automotive technology, range-extended vehicles have become one of the most frequently used modes of transportation.

[0003] In related technologies, in order to ensure the power response and range of range-extended vehicles, the range extender is usually operated directly based on the driving power demand when the remaining power of the power battery is low, so that the output of the range extender can meet the driving needs of the vehicle and charge the power battery.

[0004] However, in actual driving, when the vehicle is on a hill or under high power demand conditions such as rapid acceleration, the power demand for driving will increase significantly, forcing the range extender to operate in a high-load area. This leads to increased vehicle noise and vibration, resulting in a decrease in the overall NVH (Noise, Vibration, Harshness) performance of the vehicle, which seriously affects the user's driving comfort.

[0024] The technical solution of this application embodiment proposes a range-extending charging control method, which is detailed below. Figure 1 As shown. The method includes at least steps S110 to S130, which are described in detail below:

[0025] In step S110, the target NVH weight is determined based on the vehicle's current driving status.

[0026] It should be noted that vehicle driving status includes parameters such as driving mode, NVH level, road conditions, vehicle speed, remaining battery power, and ambient noise. Current driving status refers to the vehicle's driving state at the current moment.

[0027] In the embodiments of this application, in order to improve the NVH effect of a vehicle, the target NVH weight can be determined first based on the current driving state of the vehicle.

[0028] The method of determining the target NVH weight based on the vehicle's current driving state can be flexibly set as needed. In one example, the NVH weight associated with the current driving state can be directly obtained from the preset memory and then used as the target NVH weight. In other words, different driving states can be associated with different NVH weights in the preset memory in advance.

[0029] In another example, the basic NVH weight can be determined first by the first driving parameter in the current driving state, which is a pre-set static configuration parameter in the current driving state, such as driving mode, NVH level, energy recovery level, etc.; then the basic NVH weight can be adjusted based on the second driving parameter in the current driving state, which is a dynamic operating condition parameter that changes in real time in the current driving state, such as road condition, driving speed, remaining battery power, in-vehicle noise, etc.; and then the adjusted basic NVH weight can be used as the target NVH weight.

[0030] For example, under the following driving conditions: driving mode is Comfort, vehicle speed is 120 km / h, remaining battery power is 80%, road condition is flat, and interior noise is 65 decibels. The basic NVH weight is determined by the first driving parameter of the current driving condition, which is the NVH weight corresponding to Comfort mode. The basic NVH weight is then adjusted based on the second driving parameter of the current driving condition, using parameters such as vehicle speed of 120 km / h, remaining battery power of 80%, road condition, and interior noise of 65 decibels. Correspondingly, if the NVH weight corresponding to Comfort mode is 0.7, and the adjustment increments for vehicle speed of 120 km / h, remaining battery power of 80%, road condition, and interior noise of 65 decibels are +0.1, +0.05, 0, and +0.05 respectively, then the adjusted basic NVH weight would be 0.7 + 0.1 + 0.05 + 0 + 0.05 = 0.9.

[0031] It should be noted that the adjustment range of the basic NVH weights corresponding to the first driving parameter and the second driving parameter is positively correlated with the expected quietness experience. During the aforementioned driving process, if the driver switches to Sport mode, since Sport mode focuses more on power response than quietness compared to Comfort mode, the NVH weight corresponding to Sport mode is lower than that of Comfort mode. Therefore, the basic NVH weight determined by Sport mode is 0.4. Conversely, if the vehicle speed increases, the remaining battery power decreases, the road condition changes to uphill, or the interior noise increases, the expected power response increases, the expected energy replenishment increases, or the sensitivity to quietness decreases, all of which to some extent reflect a decrease in the expected quietness experience. Based on this, the adjustment range of the basic NVH weight is lower.

[0032] In step S120, the range extender charging power is determined based on the target NVH weight and the NVH power demand and drive power demand of the vehicle in the current driving state.

[0033] In the embodiments of this application, after determining the target NVH weight, the range-extending charging power can be determined based on the target NVH weight and the NVH power demand and drive power demand of the vehicle in the current driving state.

[0034] NVH power requirement refers to the power required by a vehicle to meet NVH standards under current driving conditions. This NVH power requirement can be obtained by looking up driving parameters in a table. For example, it can be determined by looking up the vehicle speed and remaining battery power, or by combining other driving parameters such as driving mode and NVH level.

[0035] The driving power demand is the power required by a vehicle to operate under its current driving conditions. This driving power demand can be the driving power output by the engine in the vehicle, or it can be the sum of the driving power and accessory power, where accessory power refers to the power consumed by components such as the air conditioner, headlights, and refrigerator.

[0036] Based on the target NVH weight and the NVH power demand and drive power demand of the vehicle under the current driving state, the range-extending charging power is determined in some embodiments of this application. The power ratio of NVH power demand and drive power demand can be determined separately by NVH weight. The power ratio represents the proportion of the corresponding power in the range-extending charging power. Then, the first drive power and the second drive power are calculated according to the NVH power demand, drive power demand and their respective power ratios. Finally, the sum of the first drive power and the second drive power is used as the range-extending charging power.

[0037] Specifically, assuming the target NVH weight is at most 1, the range-extending charging power can be calculated using the following formula: ;

[0038] Where X is the range-extending charging power, A is the NVH demand power, B is the drive demand power, and α is the target NVH weight, 0≤α≤1. When α=0, then X=B; when 0<α<1, A<X<B; when α=1, then X=A.

[0039] In some embodiments of this application, it can be determined whether the target NVH weight has reached a preset weight threshold. If it is determined to be yes, the NVH demand power is used as the range-extending charging power to prioritize the quietness experience of the vehicle. If it is determined to be no, the driving demand power can be used as the range-extending charging power to provide sufficient power response for the vehicle.

[0040] In step S130, the range extender in the vehicle is operated by controlling the range extender charging power.

[0041] In the embodiments of this application, after determining the range-extending charging power, the operation of the range extender in the vehicle can be controlled by the range-extending charging power.

[0042] In some embodiments of this application, the operation of the range extender in the vehicle is controlled by the range extender charging power, so that the range extender charging power can be directly used as the operating power of the range extender, so that the output power of the range extender reaches the range extender charging power.

[0043] Alternatively, you can first obtain the current operating power of the range extender, then determine the power difference between the current operating power and the range extender charging power, then determine the control step size based on the power difference, and finally adjust the operating power of the range extender by controlling the control step size until the operating power reaches the range extender charging power.

[0044] The control step size can be a preset fixed value or it can be positively correlated with the power difference. That is, the larger the power difference, the larger the control step size, so as to speed up the response.

[0045] Through the above implementation method, this application can first determine the target NVH weight based on the current driving state of the vehicle, and then determine the range-extending charging power based on the target NVH weight and the NVH power demand and drive power demand of the vehicle under the current driving state. Then, the range extender in the vehicle is controlled by the range-extending charging power, so that the vehicle can adaptively adjust the operating power of the range extender according to the target NVH weight under different operating conditions, thereby suppressing the noise and vibration generated by the range extender, thereby improving the NVH performance of the whole vehicle and improving the user's driving comfort.

[0046] See Figure 2 , Figure 2 This is an extended-range charging control method illustrated according to another exemplary embodiment. For example... Figure 2 As shown, in Figure 1 Following step S130 in the illustrated embodiment, the method may further include steps S210 to S230, as detailed below:

[0047] In step S210, the drive deficit energy is determined based on the range-extending charging power and the drive demand power.

[0048] Considering that the output power of the range extender is limited due to NVH requirements, part of the power required to drive the vehicle will be supplemented by the power battery, which will consume the power battery to a certain extent. In order to prevent the power battery from being over-discharged and affecting the vehicle's power performance, in the embodiments of this application, after controlling the operation of the range extender in the vehicle by the range extender charging power, the drive deficit energy can be determined first based on the range extender charging power and the drive demand power.

[0049] The drive deficit energy characterizes the energy difference generated by the range extender in meeting NVH requirements. Specifically, to determine the drive deficit energy, the instantaneous power difference between the range extender charging power and the drive demand power within a preset distance can be obtained first. This instantaneous power difference is then integrated over time over the time corresponding to the preset distance to obtain a cumulative energy value, which is then used as the drive deficit energy.

[0050] In step S220, a range extension compensation scheme is determined by the driving deficit energy and the current driving state.

[0051] Among them, the range extension compensation scheme is used to control the output power of the range extender in order to compensate for the drive deficit energy.

[0052] In some embodiments of this application, the process of determining the range-extending compensation scheme can be based on a preset deficit threshold and preset driving conditions. Specifically, if the driving deficit energy does not reach the preset deficit threshold and the current driving state does not meet the preset driving conditions, it indicates that the energy loss of the vehicle's current power battery is small and it is in a stable operating condition, and the first compensation scheme can be determined as the range-extending compensation scheme. Correspondingly, if the driving deficit energy reaches the preset deficit threshold or the current driving state meets the preset driving conditions, it indicates that the energy loss of the vehicle's current power battery is large or it is in a severe operating condition, and the second compensation scheme can be determined as the range-extending compensation scheme. The energy compensation rate of the second compensation scheme is higher than that of the first compensation scheme.

[0053] For example, with a preset deficit threshold of 3% of the total battery capacity and a preset driving condition where the remaining battery capacity is greater than 20%, if the driving deficit energy exceeds 3% of the total battery capacity, or if the remaining battery capacity in the current driving state is less than 20%, a second compensation scheme can be determined as the range-extending compensation scheme to quickly eliminate the energy deficit and provide sufficient energy to drive the vehicle. Conversely, if the driving deficit energy does not reach 3% of the total battery capacity and the remaining battery capacity in the current driving state exceeds 20%, a first compensation scheme can be determined as the range-extending compensation scheme, thereby reducing the impact on the vehicle's NVH performance.

[0054] In some examples of this application, the preset deficit threshold and preset driving conditions can be flexibly set according to the needs of the developers. That is, in addition to setting the preset deficit threshold as a percentage of the total power battery charge, it can also be set to a specific value (such as 1kWh or 2kWh); in addition to setting the preset driving conditions as the remaining power battery charge, it can also be set to the accelerator pedal opening, accelerator pedal change rate, etc., and there are no restrictions here.

[0055] In step S230, the range extender is controlled to operate based on the range extension compensation scheme.

[0056] In some embodiments of this application, the method of controlling the operation of the range extender based on the range extender compensation scheme can first determine the range extender compensation power corresponding to the current driving state, and then control the operation of the range extender according to the range extender compensation power, so as to flexibly adjust the output power of the range extender according to the current driving state, thereby compensating for the drive deficit energy while ensuring NVH effect.

[0057] Specifically, in some examples of this application, when the range-extending compensation scheme is the first compensation scheme, if the vehicle is in the current driving state indicating that the vehicle is on an uphill section, the range-extending charging power can be determined as the range-extending compensation power, so as to prioritize NVH performance when the remaining power battery has sufficient charge and the driving deficit energy is small.

[0058] When the range-extending compensation scheme is the first compensation scheme, if the vehicle is currently traveling on a flat road, then the first compensation power can be determined as the range-extending compensation power. This first compensation power can be greater than the driving power demand to compensate for the driving energy deficit.

[0059] When the range-extending compensation scheme is the first compensation scheme, if the vehicle is currently driving downhill, the engine load will decrease, resulting in a reduction in engine noise and vibration. Therefore, the second compensation power can be determined as the range-extending compensation power. This second compensation power can be greater than the first compensation power, thereby utilizing NVH redundancy to improve the rate of compensation for drive deficit energy while ensuring NVH performance.

[0060] When the range-extending compensation scheme is the second compensation scheme, if the vehicle is currently driving on an uphill section, the driving power demand can be determined as the range-extending compensation power to prioritize the vehicle's power response when the remaining power battery charge is low and the driving deficit energy is large.

[0061] When the range-extending compensation scheme is the second compensation scheme, if the vehicle is in a flat road or a downhill road under the current driving state, the first compensation power and the second compensation power can be used as the range-extending compensation power corresponding to the flat road and the downhill road respectively. Alternatively, the third compensation power and the fourth compensation power can be set as the range-extending compensation power corresponding to the flat road and the downhill road respectively. Among them, the third compensation power is greater than the first compensation power, and the fourth compensation power is greater than the second compensation power and the third compensation power. No restrictions are imposed here.

[0062] In addition to determining the range-extending compensation power based on the road conditions corresponding to the vehicle's current driving state, it can also be determined by combining parameters such as accelerator pedal opening, accelerator pedal change, NVH level, or driving mode under the current driving state. This improves the adaptability between the determined range-extending compensation power and the current driving state, thereby further improving the energy compensation rate while ensuring NVH performance.

[0063] In some embodiments of this application, during the process of controlling the operation of the range extender based on the range extender compensation scheme, the cumulative compensation energy can also be obtained. When the cumulative compensation energy reaches the driving deficit energy, it indicates that the range extender has completed the energy difference compensation, and the operation of the range extender based on the range extender compensation scheme can be stopped so that the vehicle can switch to normal control conditions, thereby avoiding energy waste caused by over-compensation of the range extender.
