[0027] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings in the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations.

Based on the embodiments of the present application, every other embodiment obtained by a person skilled in the art without creative work belongs to the scope of protection of the present application.

[0029] In order to enable a person skilled in the art to use the present application content, the following implementation is given in combination with a specific application scenario "vehicle technology", and the general principles defined herein can be applied to other embodiments and application scenarios without departing from the spirit and scope of the present application.

[0030] It is worth noting that before the present application is proposed, the existing technical solutions have been defined separately in respective modules, such as automobile driving modes - sport / comfort / snow, and this adjustment only has a relatively clear indication for users who are more familiar with vehicle performance, but for more users, it cannot be directly understood that the changes of various performance parameters of the vehicle, and in the adjustment process, many small vehicle attributes are divided, and for users, the adjustment details cannot be directly obtained in the aspects they want, but individual adjustment of vehicle attributes is needed. At present, the automobile multi-system linkage control only has the driving mode adjustment, which realizes the chassis hardness, power output curve, etc. by adjusting the driving mode, and there is no such multi-system linkage control energy output distribution and all free adjustable intuitive expression mode.

[0031] Based on the above problems, the embodiments of the present application provide a linkage control method and device of a vehicle and a storage medium, which solve the problem that different automobile attributes need to be adjusted one by one in the prior art.

[0032] The above-mentioned defects are the results of the inventors' practice and careful research, and thus the discovery process of the above-mentioned problems and the solutions proposed by the present application below should be the contributions of the inventors to the present application.

[0033] The technical solutions in the present application will be described clearly and completely below in conjunction with the accompanying drawings in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0034] It should be noted that similar reference numerals and letters represent similar items in the following drawings, and thus, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0035] In order to facilitate the understanding of the present application, the technical solutions provided by the present application will be described in detail below in conjunction with specific embodiments. Referring to Figure 1 shown, Figure 1 A flowchart of a linkage control method of a vehicle provided by an embodiment of the present application is shown. Figure 1 The linkage control method of a vehicle shown is executed in the vehicle-mounted processor described above.

[0036] As Figure 1 In step S101, the vehicle-mounted display screen of the vehicle is controlled to display a linkage control interface.

[0037] Specifically, the linkage control interface displays a linkage relationship network, which includes multiple nodes and edges. Each node corresponds to a control function of the vehicle, and the nodes having linkage control relationship are connected by edges. In addition, the linkage control interface also displays a standard control relationship network, which includes multiple nodes and edges. The initial display positions of the nodes and edges in the linkage relationship network on the linkage control interface coincide with the display positions of the corresponding nodes and edges in the standard control relationship network. The performance of the control functions corresponding to the multiple nodes on the linkage relationship network can be customized according to the driving habits of the user, and the standard control relationship is formulated based on the vehicle engineering principles, the correlation between performance parameters, and the universally recognized driving requirements.

[0038] It should be noted that the linkage control interface of the embodiment can be designed as an intuitive user interaction mode, and the linkage relationship network can be presented in various graphical forms, such as a multi-edge radar chart, a bar chart, and an area chart, as shown in Figure 1A Figure 1A A structural diagram of a linkage control interface provided by the embodiment of the application is shown in the figure, wherein a shadow area with an area exceeding the linkage relationship network itself is designed below the linkage relationship network, the boundary of the shadow is a maximum area in which a plurality of nodes on the linkage relationship network can move, the maximum area represents a performance limit of a control function of a vehicle corresponding to each node, different gears can be designed in the moving area of each node to represent the adjustment degree of different control functions, seven examples are used for the plurality of nodes in the embodiment, and the seven items are “air conditioner”, “light”, “speed”, “brake”, “suspension”, “steering”, and “endurance”. The method is also applicable to other parameters, and small modules such as “two-wheel drive / four-wheel drive selection”, “air spring height”, and “power corresponding gradient” can be added to the linkage relationship network to support the user to directly operate the nodes corresponding to the radar chart to adjust the energy output tendency.

[0039] In step S102, a drag operation performed on a target node on the linkage control interface is received, and a drag position of the target node after being dragged is determined.

[0040] Specifically, in the interaction process of the linkage control interface, a drag operation of a user on a specific target node (such as a vehicle control function such as “air conditioner” and “light”) is received, and a new position of the node after being dragged is accurately determined to determine the change requirement of the user for the vehicle control function corresponding to the dragged node, and the processor converts the position information into a specific control parameter value.

[0041] In step S103, according to the drag position of the target node, an adjustment position of at least one associated node having a linkage control relationship with the target node is determined.

[0042] Specifically, the vehicle-mounted processor identifies the associated nodes related to the target node, and according to a predefined linkage rule, for example, the air conditioner function and the endurance function are two interrelated function modules in the vehicle system, and they both depend on the energy in the vehicle battery, and the use of the air conditioner function will directly affect the performance of the endurance function. In this case, the air conditioner function is taken as the target node, and the endurance function is taken as the associated node. The adjustment position of the associated node is calculated according to the drag distance, the drag direction, and the strength of the linkage relationship of the target node.

[0043] In step S104, at least one associated node is displayed at the adjustment position on the linkage control interface.

[0044] ​Specifically, on the linkage control interface, when the position of the target node after being dragged is determined, and the adjustment positions of the associated nodes in linkage control relationship with the target node are calculated accordingly, the associated nodes and their new states or positions are displayed on the interface at the corresponding positions.

[0045] In step S105, according to the position changes of the target node and the at least one associated node on the linkage control interface, the control mode of the control function corresponding to the node pair is determined.

[0046] Specifically, the vehicle-mounted processor adjusts the control function corresponding to the target node according to the user's operation on the linkage control interface, for example, the operation of increasing the air conditioning function by one level, which increases the air conditioning output power and synchronously reduces the control parameter related to the cruising function, for example, reduces the engine output power, so as to maintain the overall balance of the vehicle performance, and ensure that the air conditioning effect is improved while the negative impact on the cruising ability is minimized.

[0047] In a preferred example, Figure 2 The flowchart of the control method of the automatic control button provided by the embodiment of the application is shown. Figure 2 The linkage control method shown is executed in the vehicle-mounted processor described above.

[0048] In step S201, a selection operation for the automatic control button executed on the linkage control interface is received.

[0049] Specifically, as Figure 2A shown, Figure 2A The structure diagram of another linkage control interface provided by the embodiment of the application is shown. The automatic control button is also displayed on the linkage control interface. The automatic control button can be designed in the center of the linkage relationship network, and the button and the form can be adjusted.

[0050] In step S202, in response to the selection operation, the nodes and edges in the linkage relationship network are controlled to restore to the initial display positions on the linkage control interface.

[0051] Specifically, the automatic control button can be designed to adjust the actual vehicle performance to the standard performance, which is equivalent to resetting the vehicle performance parameters, and the nodes on the linkage relationship network are moved to coincide with the nodes on the standard relationship network.

[0052] In step S203, the control function corresponding to the vehicle is controlled according to the default control mode corresponding to the initial display position.

[0053] Specifically, the vehicle-mounted processor will adjust the actual performance of the vehicle according to the initial positions, that is, the parameter values of the vehicle control function corresponding to the nodes on the standard relationship network.

[0054] In a preferred example, Figure 3 A flowchart of the linkage control method of the vehicle endurance function provided by the embodiments of the present application is shown. Figure 3 The linkage control method shown is executed in the vehicle-mounted processor described above.

[0055] In step S301, the output power of the motor of the vehicle is adjusted according to the change of the drag position of the first node relative to the display position of the first designated node corresponding to the first node in the standard control relationship network.

[0056] Specifically, the target node can be the first node corresponding to the endurance control function, the at least one associated node corresponding to the target node can be the second node corresponding to the air conditioner control function and the third node corresponding to the light control function, the linkage priority of the second node is higher than that of the third node, and the priority degree of the linkage level is set according to the association degree of the two nodes. For example, Figure 3A As shown, Figure 3A The schematic diagram for changing the vehicle endurance function in the linkage control interface provided by the embodiments of the present application is shown. The user drags the first node on the linkage control interface. This action is compared with the position of the first designated node in the standard control relationship network. The system automatically calculates and adjusts the output power of the motor of the vehicle according to the direction and distance of the drag. If the first node is dragged upwards, the power is increased. If the first node is dragged downwards, the power is decreased. The adjustment process is performed in real time, and the result is displayed through the interface feedback. At the same time, the system continuously monitors the performance to ensure safety and reasonableness.

[0057] In step S302, the air conditioner power of the vehicle is adjusted according to the adjustment position of the second node.

[0058] Specifically, adjusting the position of the second node changes the air conditioner power, and the adjustment direction is opposite to the adjustment direction of the motor output power, that is, when the motor power is increased, the air conditioner power is decreased, and when the motor power is decreased, the air conditioner power is increased, so as to balance the energy consumption of the vehicle.

[0059] In step S303, whether the light control function corresponding to the third node needs to be adjusted is judged according to the distance between the drag position of the first node and the display position of the first designated node.

[0060] Specifically, when the user drags the first node on the linkage control interface, the system judges which preset gear the first node is in or which gear the first node is closest to according to the drag position of the first node. These gears are usually divided according to different levels or ranges of vehicle performance parameters, such as low, medium and high gears, or more subdivided gears.

[0061] If adjustment is needed, step S304 is executed, and the output power of the light control function is adjusted according to the adjustment position of the third node on the linkage control interface.

[0062] Specifically, for example, when the user drags the endurance to the ninth gear, in order to further reduce the energy consumption, the system will automatically reduce the power of the light, reducing the light power can extend the endurance of the vehicle, but also on the premise of not affecting the basic driving safety, improve the energy utilization efficiency of the whole vehicle. If the user further drags the endurance to the tenth gear, some necessary safety lights (such as emergency flasher, brake light, etc.) are retained, and other lights such as headlamps, rear lights, interior lighting, etc. are completely turned off.

[0063] If no adjustment is needed, step S305 is executed, and the position of the third node on the linkage control interface is not adjusted.

[0064] Specifically, for example, when the user drags the endurance to the eighth gear, there is no critical gear position to adjust the light function, and the output power of the light is not changed.

[0065] In a preferred example, Figure 4 The flowchart of the linkage control method of the vehicle suspension function provided by the embodiments of the application. Figure 4 The linkage control method shown is executed in the vehicle-mounted processor described above.

[0066] In step S401, the height of the suspension of the vehicle is adjusted according to the change of the dragging position of the fourth node relative to the display position of the second specified node corresponding to the fourth node in the standard control relationship network.

[0067] Specifically, the target node includes a fourth node corresponding to a suspension control function, and the at least one associated node corresponding to the target node includes a fifth node corresponding to a brake control function. For example, the sensors built in the vehicle detect the dragging position of the fourth node in real time, and compare it with the position of the second specified node in the standard control relationship network. When the position change is detected, the control system of the vehicle receives the signal, and calculates the suspension height value to be adjusted according to the preset algorithm and adjusts the height of the suspension.

[0068] In step S402, the change amount of the center of gravity of the vehicle is determined.

[0069] Specifically, the change amount of the center of gravity is determined according to the first center of gravity position corresponding to the height of the suspension before adjustment and the second center of gravity position corresponding to the height of the suspension after adjustment. When the height of the suspension is adjusted, due to the change of the mass distribution of each part of the vehicle and the suspension system, the center of gravity of the vehicle will also change accordingly.

[0070] In step S403, it is judged whether the brake force needs to be adjusted according to the comparison result of the change amount of the center of gravity and the adjustment threshold.

[0071] Specifically, the position of the center of gravity of the vehicle has a direct impact on its handling, stability and braking performance. When the suspension height adjustment causes the center of gravity of the vehicle to change, this change can affect the braking distance, braking stability and braking efficiency of the vehicle. The adjustment threshold is a critical value preset according to the vehicle design, performance parameters and safety standards, etc., which represents the maximum range of acceptable center of gravity change without affecting the normal driving and braking safety of the vehicle.

[0072] If the center of gravity change is greater than the adjustment threshold, step S404 is performed to adjust the braking force according to the adjustment position of the fifth node on the linkage control interface.

[0073] Specifically, adjusting the braking force can include changing the pressure of the brake hydraulic system, adjusting the clamping force of the brake, or changing the distribution ratio of the braking force between the front and rear axles, etc.

[0074] If the center of gravity change is not greater than the adjustment threshold, step S405 is performed to not adjust the position of the fifth node on the linkage control interface.

[0075] It should be noted that in new energy vehicles, the suspension function and the braking function as key components of the vehicle system also have a significant impact on the energy management of the in-vehicle battery, and are related to the cruising range and air conditioning functions, etc., and thus the suspension function, the braking function, the cruising range and the air conditioning function can also be controlled in linkage, and the linkage control method of the present embodiment is also applicable to the optimization of these functions.

[0076] In a preferred example, Figure 5 The flowchart of the linkage control method of the vehicle speed control function provided by the embodiments of the present application. Figure 5 The linkage control method shown is executed in the vehicle-mounted processor described above.

[0077] In step S501, the engine speed of the vehicle is adjusted according to the change of the drag position of the sixth node relative to the display position of the third specified node corresponding to the sixth node in the standard control relationship network.

[0078] Specifically, the target node includes the sixth node corresponding to the speed control function, and the at least one associated node corresponding to the target node includes the seventh node corresponding to the steering control function. According to the speed adjustment value obtained by the processor, the system adjusts the engine speed of the vehicle through the engine control unit of the vehicle, which can be achieved by changing the opening degree of the throttle, adjusting the ignition advance angle, changing the fuel injection amount, etc., to realize accurate control of the engine speed.

[0079] In step S502, the torque of the steering wheel of the vehicle is adjusted according to the adjustment position of the seventh node on the linkage control interface.

[0080] Specifically, the steering wheel torque refers to the force required by the driver to rotate the steering wheel, and the change of the engine speed directly affects the power output of the vehicle. In order to maintain the power balance and stability of the vehicle during driving, the torque of the steering wheel also needs to be adjusted accordingly.

[0081] Based on the same inventive concept, the embodiment of the present application also provides a vehicle linkage control device corresponding to the vehicle linkage control method.
