[0023] To this end, the present invention proposes a power distribution method, device, electronic device and storage medium for a range-extended vehicle.

[0024] Specifically, a power distribution method, device, electronic device, and storage medium for a range-extended vehicle according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0025] Figure 1 This is a flow chart of a power distribution method for a range-extended vehicle according to one embodiment of the present invention. It should be noted that the power distribution method for a range-extended vehicle according to this embodiment of the present invention can be applied to a power distribution device for a range-extended vehicle according to this embodiment of the present invention. This device can be configured on an electronic device or on a server. The electronic device can be a PC or a mobile terminal. This is not limited in this embodiment of the present invention.

[0026] like Figure 1 As shown, the power distribution method of the range-extended vehicle includes:

[0027] S110, determining whether the vehicle is powered on.

[0028] In an embodiment of the present invention, a vehicle power-on indicator may include, for example, when no one is behind the wheel and the driver's door is closed and then opened. Alternatively, a vehicle power-on indicator may include, for example, when the vehicle is powered off and the key is inside the vehicle and the brake pedal is depressed.

[0029] S120: When it is determined that the vehicle has no navigation information, target operating condition information of the vehicle is obtained.

[0030] In an embodiment of the present invention, after it is determined that the vehicle is powered on, when it is determined that the navigation information has not been acquired, the target operating condition information of the vehicle may be acquired in real time.

[0031] The target operating condition information includes the start time, the longitude and latitude of the starting position, the longitude and latitude of the intermediate position, and the longitude and latitude of the end position.

[0032] S130 , matching the target operating condition information with the preset operating condition information, and determining whether the target operating condition information and the preset operating condition information are matched successfully.

[0033] Among them, the preset operating condition information includes first identification operating condition information, second identification operating condition information, third identification operating condition information, fourth identification operating condition information and fifth identification operating condition information, and each identification operating condition information includes one or more of the first start time, the longitude and latitude of the first starting position, the longitude and latitude of the first intermediate position and the longitude and latitude of the first end position.

[0034] That is to say, after obtaining the target operating condition information of the vehicle, the target operating condition information can be matched with each identified operating condition information, and then it can be determined whether the target operating condition information is successfully matched with any identified operating condition information.

[0035] S140 , when it is determined that the target operating condition information matches the preset operating condition information, a power distribution value between the power battery and the range extender of the range-extended vehicle is calculated based on the preset operating condition information.

[0036] In an embodiment of the present invention, upon determining that the target operating condition information successfully matches the preset operating condition information, the equivalent fuel factor of the range-extended vehicle may be calculated. The power distribution value between the vehicle's power battery and the range extender is calculated based on min((Pwr - Pwrelec) * specific fuel consumption + Pwrelec * s(t)), where Pwr represents the required power of the range-extended vehicle, s(t) represents the equivalent fuel factor, and Pwrelec represents the electric power of the range-extended vehicle. For specific implementation methods, please refer to the subsequent embodiments.

[0037] According to an embodiment of the present invention, a power allocation method for a range-extended vehicle obtains the vehicle's target operating condition information when the vehicle is powered on and when it is determined that the vehicle has no navigation information. The target operating condition information is then matched with preset operating condition information to determine whether the target operating condition information and the preset operating condition information match successfully. If a match is determined, the power allocation value between the range-extended vehicle's power battery and range extender is calculated based on the preset operating condition information. This method calculates the power allocation value between the power battery and range extender by matching the vehicle's operating condition information with the preset operating condition information when no navigation information is available, thereby reducing fuel consumption.

[0038] In order to make it easier for those skilled in the art to understand the present invention, Figure 2 It is a flow chart of the power distribution method of the range-extended vehicle, such as Figure 2 As shown, the power distribution method of the range-extended vehicle includes:

[0043] It should be noted that each identification working condition information is stored in the form of an array.

[0044] In an embodiment of the present invention, the start time in the target operating condition information is matched with the first start time. When the match is successful, the starting position longitude and latitude in the target operating condition information are further matched with the first starting position longitude and latitude. The first starting position longitude and latitude are set with a preset deviation range.

[0046] In one embodiment of the present invention, a target trajectory point of the vehicle is obtained, and based on the fact that the number of overlapping points between the target trajectory point and the first trajectory point is greater than a preset number, it is determined that the target trajectory point matches the first trajectory point, and when the matching degree between the target trajectory point and the first trajectory point is greater than a matching threshold, it is determined that the target operating condition information and the preset operating condition information are successfully matched.

[0047] S240 , when it is determined that the target operating condition information and the preset operating condition information match successfully, the equivalent fuel factor of the extended-range vehicle is calculated.
