The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0028] The first aspect of the present application provides a control method of a range extender, which is executed by a vehicle. Referring to FIG. 1, the method comprises the following steps:

[0029] Step S110: obtaining navigation information, vehicle driving parameter information, and vehicle power generation parameter information;

[0030] Among them, by obtaining the navigation information to determine the user's trip information, the user can input the navigation destination through the vehicle system or the mobile terminal, so as to generate the trip information; The trip information of the user can be the starting point, the end point in the user input navigation and the road along the road selected by the user; Selecting different road along the road will have different driving distance and road conditions, so as to consume different power; The vehicle driving parameter of different vehicle is different, that is, the power consumption capacity is different, the vehicle driving parameter information is obtained to calculate the expected power consumption of the vehicle; The vehicle power generation capacity of different vehicle is different, the vehicle power generation parameter information is obtained to calculate the expected power generation of the vehicle.

[0031] Step S120: obtaining the expected power consumption according to the navigation information and the vehicle driving parameter information;

[0032] Among them, by obtaining the vehicle driving parameter information, the power consumption capacity of the vehicle can be obtained, by obtaining the navigation information to obtain the trip information of the whole trip, according to the navigation information and the vehicle driving parameter information, the expected power consumption of the whole trip can be calculated.

[0033] Step S130: obtaining the expected power generation according to the navigation information and the vehicle power generation parameter information;

[0034] Wherein, the power generation capacity of the whole vehicle can be obtained by acquiring the power generation parameter information of the whole vehicle, the trip information of the whole trip can be obtained by acquiring the navigation information, and the expected power generation amount of the whole trip can be calculated according to the navigation information and the power generation parameter information of the whole vehicle.

[0035] Step S140: controlling the power generation of the range extender according to the expected power consumption amount and the expected power generation amount.

[0036] Wherein, the power generation process of the range extender is controlled according to the expected power consumption amount and the expected power generation amount, so that the start and shutdown of the range extender can be controlled online according to the actual demand of the user, thereby controlling the actual power generation amount of the range extender.

[0037] By acquiring the navigation information, the vehicle driving parameter and the vehicle power generation parameter, the expected power consumption amount and the expected power generation amount of the whole trip can be obtained, and the power generation process of the range extender can be controlled according to the expected power consumption amount and the expected power generation amount, so that the start and shutdown of the range extender can be controlled according to the actual demand of the user, thereby controlling the power generation amount; the working condition that is easy to be perceived by the user can be avoided, the range extension power generation can be realized, and the user is not aware; the oil-electricity conversion point of the range extender can be controlled to realize the best fuel consumption performance; the range extender can be started in advance or the power generation power can be increased to increase the power generation amount, thereby solving the problem of the user's concern about the power amount; when the slope appears, the power generation amount can also be increased in advance to increase the available power amount and increase the driving ability.

[0038] In some embodiments, referring to FIG. 2, the method comprises the following steps:

[0039] Step S210: determining the power generation amount boundary according to the range extender performance parameter, the vehicle NVH packaging parameter and the driving performance mode;

[0040] Wherein, the vehicle power generation parameter comprises the range extender performance parameter and the NVH packaging parameter, and the navigation information comprises the driving performance mode.

[0041] Specifically, the range extender performance parameter is a parameter related to the power generation capacity of the range extender. The NVH packaging is used to block the NVH interference generated by the range extender power generation to the user, so as to prevent the NVH interference from bringing bad experience to the user; the NVH packaging parameters of different vehicles can be different, and the influence degree of the NVH packaging in the process of calculating the power generation amount of the range extender can be obtained by acquiring the NVH packaging parameter.

[0042] Specifically, the driving performance mode comprises: a comfort priority mode, a power preservation priority mode and / or an energy saving priority mode.

[0043] The driving performance mode can be selected by navigation. The comfort priority mode refers to controlling the NVH performance of the vehicle to ensure that the range extender generates electricity under good NVH performance conditions, thereby ensuring the comfort of the user. The power priority mode refers to controlling the range extender to generate electricity under the condition of ensuring the power of the power battery, so that the range extender generates as much electricity as possible to consume the power of the power battery. The energy saving priority mode refers to the oil saving mode, that is, when the range extender generates electricity, the oil-electricity conversion rate of the range extender is as high as possible. Different driving performance modes consume different amounts of electricity. The power generation boundary represents the power generation range value of the current vehicle under the current driving mode. That is, different driving performance modes correspond to different power generation boundaries.

[0044] In some embodiments, referring to a characteristic diagram of a range extender shown in FIG. 3, the abscissa represents the speed of the range extender generator, and the ordinate represents the torque of the range extender. The product of the speed and the torque is the power generation power of the range extender. A plurality of curves 11 represent the NVH noise of the range extender, a plurality of curves 12 represent the oil-electricity conversion rate of the range extender, a curve 13 represents the target power generation curve of the range extender, and a plurality of curves 14 represent the power generation power of the range extender. Under different driving performance modes, the required ranges of the corresponding NVH noise, oil-electricity conversion rate, and power generation power are different, so that the power generation boundaries under each driving performance mode are different. Each driving performance mode corresponds to a target power generation curve, and power generation according to the target power generation curve can make the bias function under the driving performance optimal. For example, under the comfort priority mode, power generation according to the power generation boundary can achieve the comfort priority mode, but power generation according to the corresponding target power generation curve can make the NVH performance optimal, better meeting the needs of the user.

[0045] Step S220: segmenting the trip information to obtain a plurality of sub-trip information; wherein the navigation information includes the trip information, and each sub-trip information includes a sub-link passing speed;

[0046] The trip information includes a plurality of sub-trip information, and each sub-trip information includes a sub-link passing time. The entire trip is divided into a plurality of sub-trips, and each sub-trip information includes a sub-link passing speed of a plurality of sub-links to determine an expected sub-power generation of the current sub-link.

[0047] Step S230: obtaining the expected sub-power generation of the sub-link according to the sub-link passing speed and the power generation boundary;

[0048] The different passing speeds correspond to different driving powers, as shown in FIG. 3, the passing speed corresponds to the ordinate torque, and the corresponding power generation power curve 14 can be a plurality of curves. The torque corresponds to a power generation power value determined by the power generation boundary, and the power generation power value is selected to calculate the expected sub-power generation of the current sub-link. The power generation power value can be a maximum power value under the power generation boundary.

[0049] Step S240: summing the expected sub-power generation of each sub-section to obtain the expected power generation.

[0050] Wherein the entire trip is composed of multiple sub-sections, and the expected power generation of the entire trip is obtained by summing the expected sub-power generation of each sub-section.

[0051] In some embodiments, referring to FIG. 4, the range extender power generation is controlled according to the expected power consumption and the expected power generation, including the following steps:

[0052] Step S310: determining a target power generation curve according to the range extender performance parameters, the vehicle NVH packaging parameters and the driving performance mode;

[0053] Wherein the target power generation curve corresponding to the selected driving performance mode can be determined by the range extender performance parameters, the vehicle NVH packaging parameters and the driving performance mode, and the target power generation curve can be the optimal target power generation curve in the driving performance mode, so that the driving performance is optimized to meet the user's needs.

[0054] Step S320: comparing the size between the expected power generation and the expected power consumption;

[0055] Wherein by comparing the size between the expected power generation and the expected power consumption, it is determined whether the power generation of the range extender in the current driving performance mode can meet the demand of the expected power consumption.

[0056] Step S331: in response to the expected power generation being greater than or equal to the expected power consumption, controlling the range extender to generate power according to the passing speed of each sub-section and the target power generation curve.

[0057] Wherein if the expected power generation is greater than or equal to the expected power consumption, it means that the power generation of the range extender can meet the driving demand in the selected driving performance mode, so the range extender is controlled to generate power according to the passing speed of each sub-section and the target power generation curve to meet the user's selected driving performance demand.

[0058] Step S332: in response to the expected power generation being between the expected power consumption and the expected power range consumption, controlling the range extender to generate power according to the passing speed of each sub-section and the target power generation curve.

[0059] Wherein if the expected power generation is between the expected power consumption and the expected power range consumption, it means that the expected power generation is only slightly lower than the expected power consumption, and the driving performance mode can still be started to generate power according to the passing speed of each sub-section and the target power generation curve to meet the user's needs.

[0060] Step S333: in response to the expected power generation amount being less than the expected power consumption range amount, controlling the range extender to generate power according to the normal range extending mode;

[0061] If the expected power generation amount is less than the expected power consumption range amount, it means that the expected power generation amount cannot meet the power consumption demand in the driving performance mode, so the range extender is controlled to generate power according to the normal range extending mode to ensure the demand of the actual power consumption amount of the user.

[0062] The expected power consumption range amount is obtained by subtracting a preset range threshold from the expected power consumption range amount.

[0063] In some embodiments, referring to FIG. 5, the expected power consumption amount is obtained according to the navigation information and the vehicle driving parameter information, including:

[0064] Step S410: segmenting the trip information to obtain a plurality of sub-trip information;

[0065] The navigation information includes trip information, each sub-trip information includes a sub-road section passing time and a sub-road section passing speed, and the entire trip is divided into a plurality of sub-trips to determine the expected sub-power consumption amount of each sub-road section.

[0066] Step S420: obtaining the driving motor torque according to the sub-road section passing time, the sub-road section passing speed and the vehicle driving parameter information;

[0067] The vehicle driving parameter information includes a reducer speed ratio, a transmission shaft efficiency, a tire rolling radius, a rolling resistance coefficient, a vehicle weight, a windward area, an air resistance coefficient, a rotational mass and a transmission resistance;

[0068] The specific calculation formula of the driving motor torque T tq may be:

[0069] Wherein, δm represents the rotational mass; a represents the acceleration, u a represents the vehicle speed, t represents the sub-road section passing time; G represents the vehicle weight; f represents the rolling resistance coefficient; Cd represents the air resistance coefficient; A represents the windward area; i represents the road slope; F m represents the transmission system resistance; r represents the tire rolling radius; ig represents the reducer speed ratio; n t represents the transmission shaft efficiency.

[0070] Step S430: obtaining the driving motor speed according to the sub-road section passing speed and the vehicle driving parameter information;

[0071] Step S440: obtaining the instantaneous power according to the driving motor torque and the driving motor speed;

[0072] Step S450: obtaining the expected sub-power consumption of each sub-road section according to the instantaneous power and the passing time of each sub-road section;

[0073] The expected sub-power consumption of each sub-road section can be specifically obtained by multiplying the instantaneous power by the passing time of each sub-road section.

[0074] Step S460: summing the expected sub-power consumption of each sub-road section to obtain the expected power consumption.

[0075] The expected power consumption of the entire trip is obtained by summing the expected sub-power consumption of each sub-road section.

[0076] In some embodiments, referring to FIG. 6, after the range extender is controlled to generate power according to the expected power consumption and the expected power generation, the method further includes:

[0077] Step S510: obtaining a real-time sub-power consumption value of the current sub-road section in real time;

[0078] The actual power consumption value may be different from the expected power consumption value due to factors such as actual road conditions, for example, traffic jams, repair of the midway road, etc. The target sub-power generation of the sub-road section is corrected by obtaining the real-time sub-power consumption value of the current sub-road section in real time.

[0079] Step S520: obtaining a real-time power consumption difference value according to the real-time sub-power consumption and the expected sub-power consumption;

[0080] The real-time power consumption difference value is obtained according to the difference between the real-time sub-power consumption and the expected sub-power consumption.

[0081] Step S530: correcting the target sub-power generation according to the real-time power consumption difference value;

[0082] The target sub-power generation is corrected according to the real-time power consumption difference value, and the target sub-power generation is re-determined.

[0083] Step S540: controlling the range extender to generate power according to the corrected target sub-power generation.
