[0002] When the engine of a vehicle is working, large vibration will be generated due to the movement of the piston. As people pursue higher comfort of the vehicle, many engines are equipped with balance assemblies in order to make the engine work more smoothly.

[0057] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is made with reference to the accompanying drawings in which like reference numerals represent like elements or similar elements, unless otherwise indicated. The following exemplary embodiments described below are not representative of all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0058] The block diagrams shown in the drawings are merely functional entities and do not necessarily have to correspond to physically independent entities. That is, the functional entities can be implemented in software, or in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0059] The flowcharts shown in the drawings are merely exemplary illustrations and do not necessarily include all contents and operations / steps, nor are they necessarily executed in the order described. For example, some operations / steps can be further divided, and some operations / steps can be combined or partially combined, so that the actual execution order can be changed depending on the actual situation.

[0060] It should be noted that: in the present application, "multiple" refers to two or more. "And / or" describes the association between the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0061] Figure 1 is a flow chart of a balance assembly control method of a vehicle according to an exemplary embodiment. The method can be applied to a vehicle provided with a balance assembly, such as Figure 1 As shown in an exemplary embodiment, the balance assembly control method of the vehicle can include steps S110 to S140, which are described in detail as follows:

[0062] Step S110, obtaining the speed of the engine of the vehicle during operation and the corresponding preset speed threshold of the vehicle.

[0063] In the present application, the speed of the engine of the vehicle during operation is obtained, i.e. the speed of the crankshaft of the engine of the vehicle during operation. The corresponding preset speed threshold is set for the vehicle in advance, such as a preset speed threshold of 4500 rpm (revolutions per minute). In an embodiment, different vehicles can have different preset speed thresholds, or the same preset speed threshold, which is not limited in the present application.

[0064] Step S120, comparing the speed with the preset speed threshold to obtain a comparison result.

[0065] In the present application, the speed is compared with the preset speed threshold to obtain a comparison result. The comparison result has two types, which are respectively indicative of the speed being less than or equal to the preset speed threshold and the speed being greater than the preset speed threshold.

[0066] Step S130, determining a target control strategy for the balance assembly of the vehicle according to the comparison result.

[0067] In the present application, the target control strategy for the balance assembly of the vehicle is determined according to the comparison result, and the start-up operation or stop operation of the balance assembly is realized through the target control strategy, so that the balance assembly does not need to move all the time with the crankshaft.

[0068] In an exemplary embodiment of the present application, please refer to Figure 2 In step S130, the target control strategy for the balance assembly of the vehicle is determined according to the comparison result, which includes steps S210 and S220, which are described in detail as follows:

[0069] Step S210, if the comparison result represents that the rotation speed is less than or equal to the preset rotation speed threshold, it is determined that the target control strategy is the control strategy of stopping the operation of the balance assembly.

[0070] In the embodiments of the present application, when the comparison result represents that the rotation speed of the engine is less than or equal to the preset rotation speed threshold, the target control strategy is to control the balance assembly to stop operation. In actual use, when the engine is running at medium and low speed, that is, the rotation speed of the engine is less than or equal to the preset rotation speed threshold, the second-order reciprocating inertia force generated by the engine is small, and the counteracting second-order reciprocating inertia force generated by the balance assembly is not needed to balance. Therefore, when the rotation speed of the engine is less than or equal to the preset rotation speed threshold, the balance assembly is stopped, which saves fuel consumption to a certain extent and improves the fuel economy of the vehicle.

[0071] Step S220, if the comparison result represents that the rotation speed is greater than the preset rotation speed threshold, it is determined that the target control strategy is the control strategy of starting the operation of the balance assembly.

[0072] In the embodiments of the present application, when the comparison result represents that the rotation speed of the engine is greater than the preset rotation speed threshold, the second-order reciprocating inertia force generated by the engine causes the vehicle to vibrate, which affects the comfort of the vehicle. Therefore, the target control strategy at this time can control the balance assembly to start operation, so that the counteracting second-order reciprocating inertia force generated by the balance assembly balances the second-order reciprocating inertia force generated by the engine, thereby improving the comfort of the vehicle.

[0073] In the embodiments of the present application, the comparison result between the rotation speed of the engine and the preset rotation speed threshold is used to determine whether to start or stop the balance assembly. When the second-order reciprocating inertia force generated by the engine is small, the balance assembly is not started. When the second-order reciprocating inertia force generated by the engine is large, the balance assembly is started. In this way, the balance assembly does not need to rotate with the engine all the time, which reduces fuel consumption to a certain extent, and also takes into account the comfort of the vehicle.

[0074] In an exemplary embodiment of the present application, please refer to Figure 3 In step S130, the target control strategy for the balance assembly of the vehicle is determined according to the comparison result, which includes steps S310 to S330, which are described in detail as follows:

[0075] Step S310, a first control strategy for the balance assembly is determined according to the comparison result.

[0076] In the embodiments of the present application, the first control strategy for the balance assembly is determined according to the comparison result. The first control strategy can include the two control strategies in the foregoing steps S210 and S220.

[0077] Step S320, obtaining the driving mode of the vehicle, and determining the second control strategy for the balance assembly according to the driving mode.

[0078] In the embodiments of the present application, the vehicle is provided with corresponding driving modes. When the vehicle is switched to different driving modes, the engine fuel injection amount and the gearbox working logic are changed to affect the power output of the vehicle, so as to meet the driving style of the driver and allow the driver to experience the driving pleasure. The driving modes can include multiple modes. The second control strategy for the balance assembly is determined according to the driving mode. The second control strategy is similar to the first control strategy, and is used to control the start or stop of the balance assembly.

[0079] In an example embodiment of the present application, please refer to Figure 4 In step S320, the second control strategy for the balance assembly is determined according to the driving mode, including steps S410 and S420, which are described in detail as follows:

[0080] Step S410, if the driving mode is a specified driving mode, the second control strategy is determined to be a control strategy for stopping the operation of the balance assembly; the specified driving mode includes a kinetic energy priority mode and an oil saving mode.

[0081] In the embodiments of the present application, the vehicle is provided with specified driving modes in advance. The specified driving modes include a kinetic energy priority mode and an oil saving mode. In the kinetic energy priority mode, the engine speed of the vehicle is pulled up by the electronic control unit, which can be used when overtaking. The vehicle has high torque output at the starting stage, and the upshift time is delayed, which further increases the time for maintaining high torque. After the power is enhanced, the vehicle has stronger back-pushing feeling, and can achieve the driving experience of fast starting and fast stopping. In the oil saving mode, the vehicle drives in the oil saving mode. The vehicle computer reduces the fuel injection amount of the fuel injection nozzle, and the gearbox control module controls the shift logic of the gearbox to limit part of the power output, so that the vehicle drives in the economic fuel consumption mode. In other embodiments, the specified driving mode can also include other driving modes.

[0082] When the driving mode of the vehicle is in the specified driving mode, the second control strategy is determined to be a control strategy for stopping the operation of the balance assembly. When the specified driving mode is the kinetic energy priority mode, the power and torque consumption of the balance assembly can be reduced by stopping the operation of the balance assembly, so as to improve the power output of the engine. When the specified driving mode is the oil saving mode, the fuel consumption can be reduced by stopping the operation of the balance assembly, so as to further save fuel.

[0083] Step S420, if the driving mode is not the specified driving mode, the second control strategy is determined to be a control strategy for starting the operation of the balance assembly.

[0084] In the embodiment of the present application, if the driving mode of the vehicle is not the specified driving mode, the second control strategy is determined as the control strategy for starting the operation of the balance assembly. In the driving modes of the vehicle, the driving mode that is not the specified driving mode can include a comfort mode. The comfort mode can be used for a long time during driving. The comfort mode can achieve a good balance between economy and power. In the comfort mode, the suspension is moderately soft and hard, and the throttle response is relatively sensitive, so that the vehicle has comfort and agility.

[0085] When the driving mode of the vehicle is the comfort mode, the NVH (Noise, Vibration, Harshness) performance of the engine can be improved by starting the operation of the balance assembly.

[0086] In step S330, the target control strategy is determined according to the first control strategy and the second control strategy.

[0087] In the embodiment of the present application, the target control strategy is determined according to the first control strategy and the second control strategy. In the embodiment, the target control strategy is determined by comprehensively considering the engine speed and the driving mode of the vehicle, so that the target control strategy can balance the fuel economy and comfort of the vehicle.

[0088] In an exemplary embodiment of the present application, please refer to Figure 5 In step S330, the target control strategy is determined according to the first control strategy and the second control strategy, including steps S510 to S530, which are described in detail as follows:

[0089] In step S510, the first control strategy and the second control strategy are matched to obtain a matching result.

[0090] In the embodiment of the present application, when the target control strategy is determined according to the first control strategy and the second control strategy, the first control strategy and the second control strategy are matched to obtain a matching result. The matching result has two types, which are respectively a matching result representing that the first control strategy and the second control strategy are matched and a matching result representing that the first control strategy and the second control strategy are not matched.

[0091] In step S520, if the matching result represents that the first control strategy and the second control strategy are the same, the first control strategy or the second control strategy is selected as the target control strategy.

[0092] In the embodiment of the present application, if the matching result represents that the first control strategy and the second control strategy are the same, that is, both control strategies control the balance assembly to start operation or both control strategies control the balance assembly to stop operation, one of the first control strategy and the second control strategy is selected as the target control strategy.

[0093] Step S530, if the matching result represents that the first control strategy and the second control strategy are different, the second control strategy is taken as the target control strategy.

[0094] In the embodiment of the present application, if the matching result represents that the first control strategy and the second control strategy are different, that is, one of the two control strategies represents that the balance assembly is started to run, and the other control strategy represents that the balance assembly is stopped to run, the second control strategy is directly selected as the target control strategy.

[0095] Step S140, the balance assembly is controlled to start to run or stop to run according to the target control strategy.

[0096] In the embodiment of the present application, the balance assembly is controlled to start to run or stop to run according to the target control strategy, when the balance assembly is stopped to run, the balance assembly does not need to rotate with the engine, to a certain extent, the power and the torque consumed by the balance assembly are reduced, and the fuel consumption of the vehicle is reduced.

[0097] In an exemplary embodiment of the present application, a driving device is arranged in the vehicle, and the driving device is connected with the balance assembly; please refer to Figure 6 In step S140, the balance assembly is controlled to start to run or stop to run according to the target control strategy, which includes step S610 and step S620, and the details are introduced as follows:

[0098] Step S610, if the target control strategy is the control strategy of starting the balance assembly to run, the balance assembly is driven to run through the driving device.

[0099] In the related art, the running of the balance assembly depends on the crankshaft of the engine, the crankshaft is physically connected with the balance assembly through gears, chains or belts, so as to drive the balance assembly to run, since the crankshaft and the balance assembly are always connected together, as long as the engine starts to run, the balance assembly runs accordingly. In the embodiment of the present application, the driving device is arranged in the vehicle, the driving device is directly connected with the balance assembly, the driving device is used to drive the balance assembly to run or stop to run, so that the engine and the balance assembly run independently.

[0100] Optionally, the driving device includes a driving motor and a driving controller, and the balance assembly is integrated with the motor shaft of the driving motor. If the target control strategy is the control strategy of starting the balance assembly to run, the balance assembly is directly driven to run through the driving device, without the need to set a driving gear to drive the balance assembly to run, so as to realize the electrification of the balance assembly, and make the engine and the balance assembly run independently.

[0101] It should be noted that in the embodiment, the driving device for driving the balancing assembly is arranged to enable the engine and the balancing assembly to operate independently, so as to control the driving device according to the target control strategy; in other embodiments, the engine and the balancing assembly can also be enabled to operate independently by other means.

[0102] In an example embodiment of the present application, referring to Figure 7 In step S610, the balancing assembly is driven to operate by the driving device, including steps S710 to S730, which are described in detail as follows:

[0103] In step S710, the rotating speed of the balancing assembly is determined according to the rotating speed of the engine.

[0104] In the embodiment, the driving device is electrically connected to the ECU of the engine, and can receive the rotating speed of the engine transmitted by the ECU of the engine; when the driving device drives the balancing assembly to operate, the rotating speed of the balancing assembly should be twice the rotating speed of the engine, and the rotating speed of the balancing assembly can be quickly determined according to the rotating speed of the engine.

[0105] In step S720, the rotating direction of the engine is obtained, and the rotating direction of the balancing assembly is determined according to the rotating direction of the engine.

[0106] In the embodiment, the driving device obtains the rotating direction of the engine from the ECU of the engine, and determines the rotating direction of the balancing assembly according to the rotating direction of the engine.

[0107] In step S730, the driving device is controlled to drive the balancing assembly to operate according to the rotating speed and the rotating direction of the balancing assembly.

[0108] In the embodiment, the driving device drives the balancing assembly to operate according to the obtained rotating speed and the rotating direction of the balancing assembly.

[0109] In an example embodiment of the present application, the balancing assembly includes a first balancing shaft, a second balancing shaft, a first gear arranged on the first balancing shaft, and a second gear arranged on the second balancing shaft; the first balancing shaft is connected to the driving device, the first gear is meshingly connected to the second gear, and the materials of the first gear and the second gear include resin; in step S140, the balancing assembly is driven to operate by the driving device, including the following steps, which are described in detail as follows:

[0110] The driving device is controlled to drive the first balancing shaft to rotate, and then drive the second balancing shaft to rotate in the opposite direction to the first balancing shaft through the meshing connection between the first gear and the second gear.

[0111] In the embodiment of the present application, the balancing assembly comprises a first balancing shaft, a second balancing shaft, a first gear sleeved on the first balancing shaft, and a second gear sleeved on the second balancing shaft. The first gear and the second gear are in meshing connection. The driving device controls the rotation of the first balancing shaft. When the first balancing shaft rotates, the first gear rotates. The second gear rotates through the meshing connection between the first gear and the second gear, and then the second balancing shaft rotates. Since the first gear and the second gear are in meshing connection, the rotation directions of the first gear and the second gear should be opposite, and then the rotation directions of the first balancing shaft and the second balancing shaft are opposite. The rotation direction of the first balancing shaft is the same as the rotation direction of the crankshaft of the engine, so the rotation direction of the second balancing shaft is opposite to the rotation direction of the crankshaft.

[0112] In the embodiment of the present application, the first gear and the second gear are made of resin material. Under the action of the driving device, the resin material can meet the strength requirements of the first gear and the second gear. On the premise of ensuring reliability, the NVH performance of the engine is greatly improved.

[0113] In an example embodiment of the present application, please refer to Figure 8 The balancing assembly comprises a first balancing shaft, a second balancing shaft, a first gear disposed on the first balancing shaft, and a second gear disposed on the second balancing shaft. The first balancing shaft is connected with the driving device, and the first gear is in meshing connection with the second gear. In step S610, the driving device drives the balancing assembly to operate, which comprises the following steps S810 and S820, and the details are as follows:

[0114] In step S810, the rotation speed of the first balancing shaft is determined according to the rotation speed of the engine, and the rotation direction of the first balancing shaft is determined according to the rotation direction of the engine.

[0115] In the embodiment of the present application, the driving device is electrically connected with the ECU of the engine, and can receive the rotation speed of the engine transmitted by the ECU of the engine. In order to balance the second-order reciprocating inertia force generated by the engine, the rotation speed of the balancing assembly should be twice the rotation speed of the engine when the driving device drives the balancing assembly to operate. According to the rotation speed of the engine, the rotation speed of the first balancing shaft can be quickly determined. At the same time, the driving device obtains the rotation direction of the engine from the ECU of the engine, and determines the rotation direction of the first balancing shaft according to the rotation direction of the engine.

[0116] In step S820, the driving device is controlled to drive the first balancing shaft to rotate according to the rotation speed and the rotation direction of the first balancing shaft, so that the first gear rotates when the first balancing shaft rotates, and then the second balancing shaft rotates according to the same rotation speed as the first balancing shaft and the opposite rotation direction to the first balancing shaft through the meshing connection between the first gear and the second gear.

[0117] In the embodiment of the present application, after the driving device obtains the engine speed, the speed of the first balance shaft is determined, the speed of the first balance shaft is twice the speed of the engine, the speed of the first balance shaft is the same as the speed of the second balance shaft, therefore, the speed of the first balance shaft and the second balance shaft are both twice the speed of the engine, after the driving device obtains the direction of the engine speed, the direction of the first balance shaft is determined, the direction of the first balance shaft is opposite to the direction of the engine, the driving device controls the first balance shaft to rotate at twice the speed of the engine, and controls the first balance shaft to rotate in the direction opposite to the direction of the engine, under the joint action of the first gear and the second gear, the second balance shaft rotates at twice the speed of the engine, and rotates in the same direction as the direction of the engine.

[0118] In step S620, if the target control strategy is the control strategy of stopping the operation of the balance assembly, the driving device is controlled to stop driving the balance assembly, so that the balance assembly stops operating.

[0119] In the embodiment of the present application, if the target control strategy is the control strategy of stopping the operation of the balance assembly, the driving device is directly controlled to stop driving the balance assembly, and the balance assembly does not need to operate to balance the second-order reciprocating inertia force generated by the engine.

[0120] In the embodiment of the present application, whether the balance assembly operates or not depends on the target control strategy determined according to the engine speed, or the target control strategy determined according to the engine speed and the driving mode of the vehicle, by adjusting the target control strategy, the independent operation between the balance assembly and the engine is realized by the driving device, so that the balance assembly can stop operating when the engine operates in some working conditions, and the fuel of the vehicle is saved to a certain extent.

[0121] The embodiment of the present application also provides a vehicle, which comprises a vehicle body.

[0122] The engine and the balance assembly are arranged in the vehicle body, and the vehicle executes the balance assembly control method of the vehicle in any one of the above, so as to control the balance assembly.

[0123] In the working cycle of the engine, the movement speed of the piston is very fast, and the speed is very uneven. The speed of the piston is zero at the top dead center and bottom dead center positions, and the speed of the piston reaches the highest at the positions between the top dead center and bottom dead center. Since the piston makes repeated high-speed linear motion in the cylinder, a very large inertia force is generated on the piston, the piston pin and the connecting rod. The counterweight arranged on the connecting rod can effectively balance these inertia forces, but only part of the movement mass of the counterweight on the connecting rod participates in the linear motion, and the other part participates in the rotation. Except for the top dead center and bottom dead center positions, due to the fact that various inertia forces cannot be completely balanced, the engine generates vibration. When the piston moves up and down once, the engine generates two vibrations, one up and one down.

[0124] In order to make the engine work more smoothly, the engine is provided with a balance assembly. The existing balance assembly is driven by a driving gear, that is, a driving gear is installed on the crankshaft, a gear is installed on each of the first balance shaft and the second balance shaft in the balance assembly, the driving gear is engaged with the gear connected with the first balance shaft, and the gear on the first balance shaft is engaged with the gear on the second balance shaft. When the engine is running, the crankshaft rotates, the driving gear on the crankshaft drives the first balance shaft to rotate, and the first balance shaft drives the second balance shaft to rotate. In any working condition, the engine and the balance assembly run and stop at the same time, which consumes the power and torque of the engine and reduces the fuel economy of the vehicle.

[0125] To solve the above problems, the application provides a vehicle, please refer to Figures 9 to 12 , Figures 9 to 12 The structure diagram of the crankshaft of the engine arranged in the vehicle body and the balance assembly is as follows: Figures 9 to 12As shown, the vehicle comprises a crankshaft 1, an upper tray of balance assembly 2, a first balance shaft 3, a second balance shaft 4, a first gear 6, a second gear 5, a lower tray of balance assembly 7, a driving device 8, a lower cylinder body 9 and an upper cylinder body 10. The first balance shaft 3 and the second balance shaft 4 are installed on the lower cylinder body 9 through the upper tray of balance assembly 2 and the lower tray of balance assembly 7, the first gear 6 is arranged on the first balance shaft 3, the second gear 5 is arranged on the second balance shaft 4, the first gear 6 is in meshing connection with the second gear 5, the first balance shaft 3 is connected with the driving device 8, the driving device 8 is electrically connected with the ECU (Electronic Control Unit) of the engine, so that the driving device 8 and the ECU of the engine can interact with each other, the ECU of the engine sends the related information of the engine to the driving device 8, the driving device 8 determines the control strategy for the balance assembly according to the received related information of the engine, after obtaining the control strategy for controlling the balance assembly to start running, the first balance shaft 3 is driven to rotate, the first gear 6 is arranged on the first balance shaft 3, after the first balance shaft 3 rotates, the first gear 6 will also rotate, at the same time, since the first gear 6 is in meshing connection with the second gear 5, in the process of rotating the first gear 6, the second gear 5 is driven to rotate, further driving the second balance shaft 4 to rotate, so that the second balance shaft 4 rotates at the same speed as the first balance shaft 3 and in the opposite direction of the first balance shaft 3; after obtaining the control strategy for controlling the balance assembly to stop running, the first balance shaft 3 is directly controlled to stop rotating, and then the second balance shaft 4 also stops rotating, realizing the stop of the balance assembly. In the present application, whether to start the balance assembly is determined through the comparison result between the engine speed and the preset speed threshold value, the balance assembly does not need to rotate with the engine all the time, solving the problem of large fuel consumption, improving the fuel economy of the vehicle, at the same time, the driving gear arranged on the traditional engine is cancelled in the present application, the driving device 8 drives the start or stop of the balance assembly, realizing the electrification of the balance assembly, so that the balance assembly provided in the present application can balance the comfort and fuel economy of the vehicle, at the same time, the balance assembly can run independently with the traditional engine.

[0126] In the prior art, the crankshaft 1 of the engine directly drives the balance assembly through the driving gear, and the torsional vibration energy of the crankshaft 1 is large, so the strength requirements of the driving gear and the first gear 6 are high, and a series of NVH problems such as gear whine and knocking are caused. After the driving device 8 is used to drive the balance assembly in the present application, the strength requirements of the first gear 6 and the second gear 5 are reduced, so the first gear 6 and the second gear 5 are made of resin material to meet the strength requirements of the first gear 6 and the second gear 5. At the same time, when the two gears are engaged, the use of resin gears can reduce the whine and knocking between the gears, greatly improve the NVH performance of the balance assembly, and thus improve the NVH performance of the engine. The above-mentioned resin material can use PEEK (Poly Ether Ether ketone, polyether ether ketone) material. PEEK resin is a special engineering plastic with excellent performance, and has more significant advantages compared with other special engineering plastics. It has the advantages of high temperature resistance of 260 degrees, excellent mechanical properties, good self-lubricating property, chemical corrosion resistance, flame retardance, peeling resistance, wear resistance, strong mechanical properties, and resistance to strong nitric acid, concentrated sulfuric acid, radiation, and super mechanical properties. The first gear 6 and the second gear 5 made of PEEK material can meet the strength requirements when rotating under the action of the driving device 8.
