[0030] Currently, the camping mode achieved when a car tows a recreational vehicle is very single, only the power supply to the recreational vehicle is realized. Since the specific camping scenarios are not subdivided, the camping effect is not good.

[0031] In response to this, the present application proposes a camping control method. This method subdivides the camping mode in the driving scenario into a dynamic camping mode. After entering the dynamic camping mode, the camping control device obtains the torque adjustment strategy corresponding to the weight of the recreational vehicle, and adjusts the torque output by the car according to this torque adjustment strategy to stably tow the recreational vehicle, improving the smoothness problem when towing a recreational vehicle and enhancing the camping effect. Specifically, the method includes: if a camping instruction from the user is received during driving, then enter the dynamic camping mode; in the dynamic camping mode, obtain the torque adjustment strategy corresponding to the weight of the recreational vehicle, and adjust the torque output by the car according to the torque adjustment strategy to stably tow the recreational vehicle.

[0032] For a better understanding of the camping control method of the present application, the present application proposes an embodiment, as Figure 1 shown. Next, the present application takes the camping control device as the execution subject to illustrate the camping control method described in Figure 1 . Specifically:

[0033] 101: If a camping instruction from the user is received during driving, enter the dynamic camping mode.

[0034] Among them, the camping control device has subdivided the camping modes that can be entered when the vehicle is connected to the caravan. Whether to enter the dynamic camping mode is determined based on whether the new energy vehicle is in a driving state when the camping instruction is received. That is, if a camping instruction from the user is received during driving, enter the dynamic camping mode.

[0035] It should be noted that the above-mentioned connection between the vehicle and the caravan means that the vehicle and the caravan are connected by a power cord and / or a hitch. When the vehicle is connected to the caravan by a hitch, the vehicle can tow the caravan; when the vehicle is connected to the caravan by a power cord, the vehicle can supply power to the caravan. Therefore, in the dynamic camping mode, the vehicle and the caravan are at least connected by a hitch to tow the caravan; in the static camping mode, the vehicle and the caravan are at least connected by a power cord to achieve power supply to the caravan.

[0036] 102: In the dynamic camping mode, obtain the torque adjustment strategy corresponding to the weight of the caravan, and adjust the torque output by the vehicle according to this torque adjustment strategy to tow the caravan smoothly.

[0037] Among them, since the vehicle needs to tow the caravan in the dynamic camping mode, and the weight of the caravan is often relatively large. In order to tow the caravan, the vehicle often blindly increases the output torque, which will cause the caravan to be unstable and reduce the camping effect. In response to this, after the camping control device of this application enters the dynamic camping mode, it obtains the torque adjustment strategy corresponding to the weight of the caravan, and adjusts the torque output by the vehicle according to the torque adjustment strategy corresponding to the weight of the caravan. The torque adjustment strategy includes at least one of a torque coefficient, a gradient coefficient, and a vehicle speed coefficient. The value ranges of the torque coefficient, the gradient coefficient, and the vehicle speed coefficient are from 0 to 1. The torque coefficient, the gradient coefficient, and the vehicle speed coefficient are inversely proportional to the weight of the caravan. The greater the weight of the caravan, the smaller the coefficient and the greater the restriction. The torque coefficient is used to represent the degree of restriction on the torque of the vehicle, the gradient coefficient is used to represent the degree of restriction on the torque response rate of the vehicle, and the vehicle speed coefficient is used to represent the degree of restriction on the vehicle speed of the vehicle.

[0038] It should be noted that the camping instructions include, but are not limited to, voice instructions, touch instructions, button instructions, etc. issued by the user. In addition, the gravity of the RV can also be manually input by the user. The camping control device can obtain the camping instructions and the weight of the RV through the touch display screen. That is, when the user clicks on the camping icon on the touch display screen and inputs the weight on the touch display screen, the camping control device can obtain the camping instructions and the weight of the RV. In addition, the weight of the RV can be a specific value or an interval, such as (0, 0.7], (0.7, 1.4], and (1.4, 2] (unit: ton). The three intervals represent light, standard, and heavy respectively. The weight of the RV can also be sent by the body control module (Bcm) of the RV to the camping control device.

[0039] For step 102, the present application proposes a specific and implementable method. The above-mentioned obtaining the torque adjustment strategy corresponding to the weight of the RV and adjusting the torque output by the vehicle according to the torque adjustment strategy includes: determining the torque coefficient, gradient coefficient, and vehicle speed coefficient corresponding to the weight of the RV, where the torque coefficient, gradient coefficient, and vehicle speed coefficient are inversely proportional to the weight of the RV respectively; using the torque coefficient, gradient coefficient, and vehicle speed coefficient to weight the preset torque, preset gradient, and preset vehicle speed respectively to obtain the restricted torque, restricted gradient, and restricted vehicle speed; adjusting the torque output by the vehicle according to at least one of the restricted torque, restricted gradient, and restricted vehicle speed.

[0040] Among them, the preset torque, preset gradient, and preset vehicle speed are determined by the driving mode of the vehicle and the vehicle type style. The more sporty the vehicle type style, the larger the preset torque, preset gradient, and preset vehicle speed. The larger the preset torque, the greater the torque that can be output and the stronger the power; the larger the preset gradient, the faster the torque response and the stronger the acceleration ability; the larger the preset vehicle speed, the higher the vehicle speed that can be reached. To illustrate the above process of calculating the restricted torque, restricted gradient, and restricted vehicle speed, for example, N represents the restricted torque, β represents the torque coefficient, and N max represents the preset torque; K = α * K max , where K is the restricted gradient, α represents the gradient coefficient, and K max represents the preset gradient; V = γ * V max , where V represents the restricted vehicle speed, γ represents the vehicle speed coefficient, and V max represents the preset vehicle speed. In addition, when it is detected that the duration of the throttle opening being greater than 98% is greater than or equal to 2 seconds or in the case of detecting a large slope, etc., in order not to affect the torque output in the actual large torque scenario, the camping control device can make the torque coefficient β = 1.

[0041] It should be noted that the present application can adjust the torque output by the vehicle according to one or more of the limiting torque, limiting gradient, and limiting vehicle speed. Next, four implementation manners of the present application are proposed to illustrate this, specifically:

[0042] In the first implementation manner, the camping control device adjusts the torque output by the vehicle according to the limiting torque, that is, controls the torque output by the vehicle to be less than or equal to the limiting torque, so as to prevent the vehicle from having too strong power output and insufficient stability when outputting at full throttle. For example, the camping control device outputs the minimum value of the limiting torque and the user demand torque. This step can be expressed by the mathematical formula as X = min[M, N], where X is the torque to be output (that is, the desired output torque), M is the user demand torque, and N is the limiting torque. The user demand torque is the torque requested by the user, and the magnitude of the user demand torque depends on the vehicle speed and the throttle opening.

[0043] In the second implementation manner, the camping control device adjusts the torque output by the vehicle according to the limiting gradient, that is, controls the vehicle to output torque according to the limiting gradient, so as to reduce the torque response rate and make the acceleration process of the vehicle relatively gentle, thereby improving the smoothness of the RV. For example, the step of the camping control device adjusting the torque output by the vehicle according to the limiting gradient can be expressed by the mathematical formula as Y = Y n-1 + min[(X - Y n-1 ),(K max * T * α)], where Y represents the torque to be output, Y n-1 represents the torque output in the previous cycle, X represents the desired output torque, T represents the step value (generally, T can be set to 1), α represents the gradient coefficient, and K max represents the preset gradient.

[0044] In the third implementation manner, the camping control device adjusts the torque output by the vehicle according to the limiting vehicle speed, that is, when the vehicle speed of the vehicle quickly reaches the limiting vehicle speed, reduces the output torque, so that the vehicle speed is less than or equal to the limiting vehicle speed, thereby improving the smoothness of the RV.

[0045] The fourth implementation mode: The camping control device adjusts the torque output by the vehicle according to the limiting torque, limiting gradient, and limiting vehicle speed, that is, while controlling the torque output by the vehicle to be less than or equal to the limiting torque, the torque is output according to the limiting gradient, and the vehicle speed is controlled to be less than or equal to the limiting vehicle speed. Specifically, after the vehicle starts, the camping control device monitors whether the difference between the limiting vehicle speed and the current vehicle speed is greater than zero; if so, it outputs the minimum value between the limiting torque and the user demand torque according to the limiting gradient; if not, it reduces the torque currently output by the vehicle according to the limiting gradient until the vehicle speed of the vehicle is less than or equal to the limiting vehicle speed. For example, when the current vehicle speed of the vehicle is 60 km / h, which is less than the limiting vehicle speed of 100 km / h, it is determined that the vehicle is not speeding. At this time, if the limiting torque is greater than the user demand torque, the camping control device outputs the user demand torque according to the limiting gradient, otherwise it outputs the limiting torque according to the limiting gradient, so that the new energy will not suddenly increase the power. For example, when the current vehicle speed of the vehicle is 110 km / h, which is greater than the limiting vehicle speed of 100 km / h, it is determined that the vehicle is speeding. At this time, in order to return to below the limiting vehicle speed, the camping control device reduces the torque currently output by the vehicle according to the limiting gradient, so as to reduce the vehicle speed while smoothly reducing the torque of the vehicle, thereby improving the stability of the RV.

[0046] In summary, the embodiments of the present application subdivide the camping mode when the vehicle is connected to the RV, provide camping control in the dynamic camping mode, improve the smoothness of the RV during movement, and solve the problem of poor camping effect in the prior art.

[0047] In addition, on the basis of the foregoing embodiments, the present application also provides another embodiment of the camping control method, as Figure 2 shown. Next, the present application will use the camping control device as the execution subject to describe Figure 2 the described camping control method. Specifically:

[0048] 201: If a camping instruction from the user is received during driving, enter the dynamic camping mode.

[0049] 202: In the dynamic camping mode, obtain the torque adjustment strategy corresponding to the weight of the RV, and adjust the torque output by the vehicle according to the torque adjustment strategy to smoothly tow the RV.

[0050] Among them, the specific implementation processes of steps 201 to 202 can refer to steps 101 to 102 of the previous embodiment, and the embodiments of the present application will not elaborate here. In addition, the present application does not limit the execution order of steps 201 and 203. The camping control device can only enter one of the dynamic camping mode and the static camping mode. It can first enter one of the dynamic camping mode and the static camping mode, and enter the other mode after exiting this mode.

[0051] 203: If a camping instruction from the user is received during the parking process, enter the static camping mode.

[0052] Among them, in the camping control mode, if a camping instruction from the user is received during the vehicle parking process, enter the static camping mode. Parking includes being completely stationary and driving at a low speed (e.g., 0.2 km / h).

[0053] 204: In the static camping mode, control the power generation power to be less than or equal to the first power to reduce noise.

[0054] Among them, in order to improve the camping effect in the static camping mode, after entering the static camping mode, the camping control device controls the power generation power to be less than or equal to the first power. The first power is equal to the power supply power. Since the power supply power is a relatively small power, e.g., 3 kw, when the camping control device controls devices such as the range extender to generate power at the first power, the noise generated by power generation is relatively small.

[0055] Regarding step 202, in order to further reduce noise and improve the camping effect, the present application proposes a specifically implementable method. The step of controlling the power generation power to be less than or equal to the first power in the static camping mode includes: monitoring whether the remaining battery power is less than or equal to the first power; if it is monitored that the remaining power is less than or equal to the first power, control the range extender to generate power at a power generation power less than or equal to the first power, where the first power is greater than or equal to the power to start the range extender.

[0056] Among them, in the static camping mode, when the remaining power of the vehicle's battery is relatively sufficient, the camping control device prohibits the range extender from generating power until the remaining battery power is in an emergency situation, and then controls the range extender to generate power. In order to minimize noise as much as possible, the camping control device can set the first power equal to the power to start the range extender, and when the remaining battery power is greater than the first power, prohibit the range extender from starting until it is monitored that the remaining battery power is equal to the first power, and then control the range extender to generate power at the first power. For example, the first power can be 17%. In order to further reduce power consumption, after entering the static camping mode, the camping control mode can also control the vehicle to exit the slippery mode.

[0057] In order to further improve the camping effect, the present application also proposes an implementable method. In the dynamic camping mode, the camping control device can also monitor whether the remaining battery power is less than the second power; if it is monitored that the remaining power is less than the second power, control the range extender to generate power at a power generation power greater than or equal to the second power, where the second power is equal to the sum of the power supply power and the traction power. When the remaining power is greater than or equal to the second power, the duration for which the vehicle can supply power to the RV is greater than or equal to the preset camping duration.

[0058] Among them, in order to have sufficient power to maintain power supply in the static mode and minimize the start of the range extender to reduce motor noise, the camping control device monitors the battery power in the dynamic camping mode. If the battery power is greater than or equal to the second power (for example, 70%), it means that the battery power is sufficient to supply power to the RV for more than the preset camping duration (for example, 12 hours). At this time, there is no need to control the range extender to generate electricity. Otherwise, the range extender is controlled to generate electricity at a power generation power greater than or equal to the second power, so that the power generated by the range extender can supply power to the RV while towing the RV and maintain a high battery level. In addition, in the static camping mode, the present application also proposes an implementable method. Specifically, in the static camping mode, if it is detected that the vehicle is locked and there are people in the vehicle, the operation instructions of the user are received through voice; if the operation instructions are received within the first preset duration, the camping operations are performed according to the operation instructions, where the camping operations include closing the windows, adjusting the seat angle, and / or the air conditioning temperature; if the operation instructions are not received within the first preset duration, the user is prompted whether to perform the camping operations, and if the operation instructions of the user are not received within the second preset duration after prompting the user, the camping operations are performed according to the default instructions.

[0059] Among them, the implementation manner of the present application can also realize simultaneous camping of the RV and the car. For example, in the static camping mode, if it is detected that the vehicle is locked and powered off and there is no one in the vehicle, the instrument screen is turned off, the brightness of the large screen is reduced to 30% and the clock is displayed, and the whole vehicle continuously maintains a high-voltage state until the static camping mode is exited; if it is detected that the vehicle is locked and there are people in the vehicle, the user can issue operation instructions within the first preset duration (for example, 5 minutes) to instruct the camping control device to perform at least one camping operation such as closing the windows, adjusting the seat angle, and the air conditioning temperature. However, if the operation instructions are not received within the first preset duration, the user is prompted by voice whether to perform the foregoing camping operations. If the operation instructions are still not received within the second preset duration (for example, 30 seconds) after the prompt, the foregoing camping instructions are performed according to the default instructions.

[0060] In summary, the present application not only proposes a dynamic camping mode, but also a static camping mode, further subdividing the camping mode when the car is connected to the RV. In the static camping mode, the camping control device can improve the camping effect by reducing noise. In the dynamic camping mode, the camping control device can improve the camping effect by increasing the stability of the RV during movement.

[0061] The implementation of the present invention also provides a camping control device. In one embodiment, see Figure 3。Embodiments of the present invention can divide the device into functional units according to the above method examples. For example, each functional unit can be divided corresponding to each function, or two or more functions can be integrated into one unit. The above integrated unit can be implemented in the form of hardware or in the form of a software functional unit. It should be noted that the division of units in the embodiments of the present invention is illustrative, only a logical function division, and there can be other division methods in actual implementation. As Figure 3 shown, the camping control device includes a receiving unit 310 and a control unit 320. Specifically: The receiving unit 310 is configured to enter the dynamic camping mode if a camping instruction from a user is received during driving; The control unit 320 is configured to, in the dynamic camping mode, obtain a torque adjustment strategy corresponding to the weight of the RV, and adjust the torque output by the vehicle according to the torque adjustment strategy to stably tow the RV.
