[0002] A range-extended electric vehicle is an electric vehicle that uses other energy sources (such as gasoline) to replenish its electrical power when the battery is low.

[0003] Currently, the control methods for range extenders in range-extended electric vehicles are relatively simple. Typically, the range extender is activated to replenish power when the battery level drops below a certain calibrated value. However, in certain scenarios, the traditional control method for range extenders suffers from inadequate control. Summary of the Invention

[0028] The judgment module is used to determine whether the current state of the vehicle meets preset conditions after the vehicle enters the camping mode. The camping mode is controlled to enter the vehicle after receiving the camping mode activation command. The preset conditions include the vehicle being in a parked state, the battery level not exceeding a first preset value, and the vehicle not having a preset level fault.

[0029] The starting module is used to send a starting command to the vehicle's range extender after determining that the current state meets the preset conditions, so that the range extender can pre-replenish the vehicle's battery with electrical energy.

[0030] The shutdown module is used to send a shutdown command to the range extender after determining that the battery charge is not less than a second preset value.

[0031] In one possible implementation, the parking state includes some or all of the following states:

[0033] The vehicle is in neutral.

[0034] The vehicle speed is a preset speed;

[0060] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0061] It should be noted that the terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in sequences other than those illustrated or described herein.

[0062] To address the issue of unreasonable control in traditional range extender control methods, this embodiment of the application, after the vehicle enters camping mode, determines whether the vehicle's current state meets preset conditions; and upon confirming that the current state meets the preset conditions, sends a start command to the vehicle's range extender to pre-charge the vehicle's battery; and, upon confirming that the battery charge is not less than a second preset value, sends a stop command to the range extender. The camping mode is activated upon receiving the camping start command. The preset conditions include the vehicle being in a parked state, the battery charge not exceeding a first preset value, and the absence of a preset level of fault in the vehicle. This achieves reasonable control of the range extender's start and stop, optimizes the control scheme, and improves the user experience.

[0063] The preferred embodiments of this application will be further described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. Furthermore, the embodiments of this application and the features in the embodiments can be combined with each other without conflict.

[0064] See Figure 1 As shown in the figure, the control method for a range extender provided in this application embodiment has the following specific process:

[0065] Step 100: After the vehicle enters camping mode, determine whether the current state of the vehicle meets the preset conditions. Camping mode is activated by controlling the vehicle to enter after receiving the camping mode activation command. The preset conditions include the vehicle being parked, the battery level not exceeding a first preset value, and the vehicle not having a preset level fault.

[0066] In the embodiments of this application, see the following: Figure 2 As shown, the vehicle controller puts the vehicle into camping mode by performing the following steps:

[0067] Step 200: Receive the camping mode activation command, which is sent by a remote device or triggered by the user performing a preset operation on the vehicle.

[0068] In this embodiment of the application, the above-mentioned camping mode activation command can be sent through a remote device or triggered after the user performs a preset operation on the vehicle.

[0069] In some feasible embodiments, the remote device described above includes any one of the following devices:

[0070] Equipment 1: Remote control equipment.

[0071] For example, the remote control platform sends a command to the vehicle to activate camping mode.

[0072] Device 2: Intelligent terminal associated with the vehicle.

[0073] For example, a user can send a command to the vehicle to activate camping mode via a smart terminal that has the corresponding application installed on the vehicle.

[0074] In some feasible embodiments, the above-mentioned preset operation includes any one of the following operations:

[0075] Operation 1: Press the camping button.

[0076] In some embodiments, a physical button, referred to as the camping button, can be added to the vehicle. When the user presses the camping button, a camping mode activation command is triggered.

[0077] In practice, when the camping button is pressed, the camping button is connected to the battery, and the vehicle controller receives the camping hardwire signal, which is the command to activate the camping mode.

[0078] Step 2: Click on the preset area in the display screen.

[0079] In some embodiments, the vehicle may have touch screen control functionality, so when a user performs a click operation on a preset area in the vehicle's display screen, the above-mentioned camping mode activation command is triggered.

[0080] Operation 3: Voice operation.

[0081] In some embodiments, the vehicle may have voice control functionality, so when the user performs a voice operation on the vehicle, the above-mentioned camping mode activation command is triggered.

[0082] Step 210: Based on the camping mode activation command, control the vehicle to enter camping mode.

[0083] In this embodiment of the application, when performing step 210, the vehicle is controlled to enter the camping mode based on the camping mode activation command. The camping mode has a memory function, that is, if the vehicle controller receives the camping mode activation command in advance, the vehicle controller will automatically control the vehicle to enter the camping mode after the next power-on before receiving the camping mode cancellation command.

[0084] In the embodiments of this application, see the following: Figure 3 As shown, after performing step 210, the following steps can also be performed:

[0085] Step 2101: The control instrument display component illuminates the camping mode indicator corresponding to the camping mode; and / or, sends a preset message to the remote control platform, so that the remote control platform sends a preset message to the smart terminal associated with the vehicle, wherein the preset message is used to remind the user that the vehicle has entered camping mode.

[0086] In practice, the vehicle controller sends a camping mode signal to the instrument display unit, which then illuminates the corresponding camping mode icon based on the signal; and / or, sends a camping mode signal to the in-vehicle remote communication terminal (Telematics-BOX, in-vehicle T-BOX). The T-BOX uploads a preset message to the remote control platform, which then sends the preset message to the APP in the smart terminal associated with the vehicle to remind the user that the vehicle has entered camping mode.

[0087] In this embodiment of the application, after describing when the vehicle enters the camping mode and that the camping mode has a memory function, step 100 is executed each time the vehicle controller is powered on. After the vehicle enters the camping mode, it is determined whether the current state of the vehicle meets the preset conditions, that is, whether the vehicle is in a parked state, whether the battery charge is not greater than the first preset value, and whether the vehicle does not have a preset level fault.

[0088] In this embodiment of the application, the above-mentioned parking state includes some or all of the following states:

[0089] Status 1: The vehicle's high-voltage system is in a successfully started state.

[0090] In this embodiment of the application, the vehicle's high-voltage system is in a successfully started state, meaning that the vehicle can start at any time.

[0091] In some embodiments, the vehicle's instrument display is equipped with a "ready" indicator, which signifies that the vehicle is fully prepared, has started successfully, and is ready to depart at any time. Therefore, when the vehicle's "ready" indicator is illuminated, the vehicle is in state 1: the high-voltage system has successfully started.

[0092] Status 2: The vehicle is in neutral.

[0093] The neutral gear mentioned above is N gear.

[0094] Status 3: The vehicle speed is the preset speed.

[0095] The preset speed is 0 km / h.

[0096] Status 4: The vehicle's handbrake is in the parking position.

[0097] In this embodiment, the aforementioned preset fault level refers to vehicle faults of level three or higher. Level three faults mainly occur in scenarios where there are malfunctions in the powertrain, such as motor overheating, battery overcharging, over-discharging, undervoltage, DC-DC converter malfunction or abnormal operation, or vehicle collision. Correspondingly, faults of level three or higher correspond to scenarios more severe than level three faults.

[0098] Step 110: After determining that the current state meets the preset conditions, send a start command to the vehicle's range extender so that the range extender can pre-replenish the vehicle's battery with electrical energy.

[0099] In this embodiment of the application, after executing step 110, the range extender receives the start command and can pre-replenish the battery with power at a preset power, wherein the preset power can be 60kw / h.

[0100] Step 120: After confirming that the battery charge is not less than the second preset value, send a shutdown command to the range extender.

[0101] In this embodiment of the application, after executing step 110, the battery power sent by the battery power sensor is continuously received. After determining that the battery power is not less than a second preset value, step 120 is executed to send a shutdown command to the range extender.

[0102] In the embodiments of this application, see the following: Figure 4 As shown, the first and second preset values ​​are determined in the following manner:

[0103] Step 400: Determine the first power consumption for each of the target electrical devices in the vehicle based on their rated power and preset power consumption duration.

[0104] In this embodiment of the application, when performing step 400, the first power consumption corresponding to each target electrical device is calculated respectively. The preset power consumption time of each target electrical device is preset based on experimental data and empirical data.

[0105] For example, see Figure 5 As shown, taking vehicle A as an example.

[0106] Assume vehicle A is equipped with a camping button, air conditioning, washing machine, refrigerator, television, induction cooker, and lighting equipment.

[0107] So, when the user presses the camping button, the vehicle controller puts the vehicle into camping mode.

[0108] Then, through the gateway, camping mode information is sent to the instrument display component, controlling the instrument display component to light up the camping mode icon corresponding to the camping mode; through the gateway, camping mode information is sent to the vehicle T-BOX, the vehicle T-BOX sends the preset information to the remote control platform, and the remote control platform sends the preset message to the smart terminal associated with the vehicle to remind the user that the vehicle has entered camping mode.

[0109] Next, based on the rated power and preset power consumption time of each target electrical device, the corresponding first power consumption is determined. The target electrical devices are any one of air conditioners, washing machines, refrigerators, televisions, induction cookers, and lighting equipment.

[0110] Assume the rated power and preset power consumption duration of each of the above target electrical devices are as shown in the table below:

[0111] Table 1

[0112] name air conditioner washing machine refrigerator television induction cooker Lighting equipment Rated power B1 B2 B3 B4 B5 B6 Preset power consumption time C1 C2 C3 C4 C5 C6

[0113] Based on the table above, the initial power consumption of each target electrical device is determined as follows:

[0114] Table 2

[0115] name air conditioner washing machine refrigerator television induction cooker Lighting equipment First power consumption B1*C1 B2*C2 B3*C3 B4*C4 B5*C5 B6*C6

[0116] Step 410: Determine the vehicle's first total power consumption based on each first power consumption.

[0117] In this embodiment of the application, when performing step 410, the first power consumption is summed to obtain the first total power consumption.

[0118] Step 420: Determine the first preset value based on the sum of the first total power consumption and the first preset redundant power, as well as each preset power value.

[0119] In this embodiment of the application, in order to ensure sufficient power reserve, a first preset redundant power is set. So, after obtaining the first total power consumption in step 410, when executing step 420, firstly, the first total power consumption and the first preset redundant power are summed to obtain the sum of the first total power consumption and the first preset redundant power. Then, the sum of the first total power consumption and the first preset redundant power is compared with each preset power value, and the first preset value is determined based on the comparison result.

[0120] For example, let's take vehicle A as an example again.

[0121] The State of Charge (SOC) is usually used to reflect the remaining capacity of a battery. It is numerically defined as the ratio of the remaining capacity to the battery capacity, usually expressed as a percentage. Its value ranges from 0 to 1. When SOC = 0, it means that the battery is completely discharged, and when SOC = 1, it means that the battery is completely charged.

[0122] Assume the relationship between the SOC percentage of vehicle A's power battery and the preset battery capacity is as shown in the table below:

[0123] Table 3

[0124] SCO percentage 100％ 90％ 80％ 70％ 60％ 50％ 40％ 30％ 20％ 10％ Preset battery level S10 S9 S8 S7 S6 S5 S4 S3 S2 S1

[0125] Then, after performing a summation operation on the first total power consumption and the first preset redundant power consumption to obtain the sum of the first total power consumption and the first preset redundant power consumption, the sum of the first total power consumption and the first preset redundant power consumption is compared with the above-mentioned preset power consumption (i.e., S10 to S1) to obtain the first preset value.

[0126] In specific implementation, the preset power value that is closest to the sum of the first total power consumption and the first preset redundant power consumption, and is greater than the sum of the first total power consumption and the first preset redundant power consumption, is selected from the preset power values ​​(i.e., S10 to S1) as the first preset value.

[0127] For example, if the first preset redundant power is 5 kW / h, the sum of the first total power consumption and the first preset redundant power (B1*C1+B2*C2+B3*C3+B4*C4+B5*C5+B6*C6+5 kW / h) is 500 kW / h, S4 is 480 kW / h and S5 is 550 kW / h, then the preferred first preset value is S5.

[0128] Step 430: Based on the sum of the first total power consumption and the second preset redundant power consumption, and each preset power consumption value, determine the second preset value, wherein the second preset redundant power consumption is greater than the first preset redundant power consumption.

[0129] In this embodiment of the application, in order to ensure sufficient power reserve, a second preset redundant power is set. So, after obtaining the first total power consumption in step 410, when executing step 430, firstly, the first total power consumption and the second preset redundant power are summed to obtain the sum of the first total power consumption and the second preset redundant power. Then, the sum of the first total power consumption and the first preset redundant power is compared with each preset power value, and the second preset value is determined based on the comparison result.

[0130] In specific implementation, the preset power value that is closest to the sum of the first total power consumption and the second preset redundant power consumption, and is greater than the sum of the first total power consumption and the second preset redundant power consumption, is selected as the second preset value.

[0131] For example, if the second preset redundant power is 30kw / h, the sum of the first total power consumption and the second preset redundant power (B1*C1+B2*C2+B3*C3+B4*C4+B5*C5+B6*C6+30kw / h) is 500kw / h, S4 is 450kw / h and S5 is 550kw / h, then the second preset value is preferably S5.

[0132] Based on the same inventive concept, see [reference] Figure 6 As shown in the figure, this application provides a control device for a range extender, including:

[0133] The judgment module 610 is used to determine whether the current state of the vehicle meets preset conditions after the vehicle enters the camping mode. The camping mode is controlled to enter the vehicle after receiving the camping mode activation command. The preset conditions include the vehicle being in a parked state, the battery level not exceeding a first preset value, and the vehicle not having a preset level fault.

[0134] The starting module 620 is used to send a starting command to the range extender of the vehicle after determining that the current state meets the preset conditions, so that the range extender can pre-replenish the battery of the vehicle.

[0135] The shutdown module 630 is used to send a shutdown command to the range extender after determining that the battery charge is not less than a second preset value.

[0136] In one possible implementation, the parking state includes some or all of the following states:

[0137] The vehicle's high-voltage system is in a successfully started state;

[0138] The vehicle is in neutral.

[0139] The vehicle speed is a preset speed;

[0140] The vehicle's handbrake is in the park position.

[0141] In one possible implementation, the first preset value and the second preset value are determined in the following manner:

[0142] Based on the rated power and preset power consumption duration of each target electrical device in the vehicle, the corresponding first power consumption is determined.

[0143] Based on each first power consumption, the first total power consumption of the vehicle is determined;

[0144] Based on the sum of the first total power consumption and the first preset redundant power, as well as each preset power value, the first preset value is determined;

[0145] Based on the sum of the first total power consumption and the second preset redundant power consumption, and the various preset power consumption values, the second preset value is determined, wherein the second preset redundant power consumption is greater than the first preset redundant power consumption.

[0146] In one possible implementation, the vehicle is controlled to enter the camping mode in the following manner:

[0147] Receive command to activate camping mode;

[0148] Based on the camping mode activation command, control the vehicle to enter the camping mode;

[0149] The camping mode activation command is sent via a remote device or triggered by the user performing a preset operation on the vehicle. The remote device includes any one of the following: a remote control device; a smart terminal associated with the vehicle. The preset operation includes any one of the following: pressing the camping button; clicking a preset area on the display screen; or voice operation.

[0150] In one possible implementation, after controlling the vehicle to enter the camping mode, the determination module 610 is further configured to:

[0151] The control instrument display unit illuminates the camping mode indicator corresponding to the camping mode; and / or

[0152] A preset message is sent to the remote control platform, so that the remote control platform sends the preset message to the smart terminal associated with the vehicle, wherein the preset message is used to remind the user that the vehicle has entered the camping mode.
