Background Art

[0002] Tire pressure plays a vital role in the performance of the car. Appropriate tire pressure can ensure good braking performance, handling and comfort. If the tire pressure is too low, it will increase the vehicle's fuel consumption, aggravate tire wear, cause the tire temperature to rise and cause a tire blowout, affect the braking distance, and cause the vehicle to drive abnormally bumpy.

[0003] In related technologies, vehicles are generally equipped with a tire pressure monitoring system. When the tire pressure is lower than the set value, the vehicle's dashboard will prompt the driver that the tire pressure is low, and the driver will drive to refill the tires of the vehicle. Tire pressure detection technology can greatly reduce the probability of using a vehicle at extremely low tire pressure. However, when the tire pressure drops from the rated value to the alarm value, the vehicle's fuel consumption, braking performance, handling and comfort have been affected. Summary of the invention

DETAILED DESCRIPTION

[0044] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0045] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

[0046] As mentioned in the background technology section, tire pressure plays a vital role in the performance of the car. Appropriate tire pressure can ensure good braking performance, handling and comfort. If the tire pressure is too low, it will increase the fuel consumption of the vehicle, aggravate tire wear, cause the tire temperature to rise and cause tire blowout, affect the braking distance, and cause abnormal bumps in the vehicle.

[0047] In the process of realizing the present invention, the applicant discovered that in the related art, vehicles are generally equipped with a tire pressure monitoring system. When the tire pressure is lower than the set value, the vehicle's dashboard will prompt the driver that the vehicle's tire pressure is low, and the driver will drive to inflate the vehicle's tires. Tire pressure detection technology can greatly reduce the probability of using a vehicle at extremely low tire pressure. However, when the tire pressure drops from the rated value to the alarm value, the vehicle's fuel consumption, braking performance, handling and comfort have been affected.

[0048] Therefore, the present invention can determine whether it is necessary to inflate the tires of the target vehicle according to the tire pressure data of the tires. When it is necessary to inflate the tires of the target vehicle, the inflation mechanism is driven by the wheel-end motor to inflate the tires of the target vehicle, so that the tire pressure can be stabilized within the optimal range, thereby improving the power economy, braking performance, handling and comfort of the vehicle and tires, reducing the vehicle's fuel consumption, reducing tire wear, and reducing the risk of tire blowout.

[0049] The following describes, with reference to the accompanying drawings, an EMB-based intelligent tire inflation system, a control method of an EMB-based intelligent tire inflation system, a control device of an EMB-based intelligent tire inflation system, an electronic device, a storage medium, and a vehicle proposed in an embodiment of the present invention.

[0050] refer to Figure 1 , is a block diagram of an EMB-based intelligent tire inflation system according to some embodiments of the present invention.

[0051] The EMB-based intelligent tire inflation system 1000 of the present invention includes a wheel-end motor 10 , a valve mechanism 60 , a connecting mechanism 40 , an EMB controller 80 , an inflation mechanism 30 , a tire pressure sensor 70 and an electronic clutch 20 .

[0052] The wheel-end motor 10 is arranged corresponding to the tire 50 of the target vehicle, and the number of the wheel-end motor 10 can be at least one, that is, only one wheel-end motor 10 is arranged on one of the four tires 50 of the target vehicle. Preferably, the number of the wheel-end motor 10 is four, and one wheel-end motor 10 is arranged for each tire 50 of the target vehicle.

[0053] The inflation mechanism 30 is disposed on the wheel-end motor 10 , wherein the inflation mechanism 30 may be a micro air pump, and the wheel-end motor 10 and the inflation mechanism 30 constitute a wheel-end module of the EMB.

[0054] Exemplarily, the inflation mechanism 30 can also be a vehicle-mounted air pump, which usually has two types: wired and wireless. The wired air pump needs to be connected to the cigarette lighter or power interface of the target vehicle, while the wireless air pump has a built-in battery and is more convenient to use. The vehicle-mounted air pump can inflate the tire 50 of the target vehicle.

[0055] The valve mechanism 60 is arranged on the tire 50 of the target vehicle, wherein the valve mechanism 60 can be an auxiliary valve nozzle, the valve mechanism 60 can serve as an air injection port of the tire 50, the valve mechanism 60 allows gas to enter the space of the tire 50 or the inner tube, and automatically closes after inflation to seal and preserve the gas. The valve mechanism 60 is a channel for the tire 50 to exchange gas with the outside world.

[0056] Exemplarily, there are two valves and two valve nozzles, and each valve is provided with a valve nozzle. One valve nozzle is used to inflate the vehicle's tire 50 by conventional means (such as manual inflation), and the other valve nozzle is used to perform the intelligent tire inflation operation proposed by the present invention on the vehicle's tire 50.

[0057] Alternatively, the number of valves is one and the number of valve nozzles is two. One valve is provided with two valve nozzles, and the two valve nozzles are not related, that is, the two valve nozzles do not interfere with each other. One valve nozzle is used to inflate the vehicle's tire 50 by conventional means (such as manual inflation), and the other valve nozzle is used to perform the intelligent tire inflation operation proposed by the present invention on the vehicle's tire 50.

[0058] The connecting mechanism 40 is arranged between the inflation mechanism 30 and the valve mechanism 60, and is used to control the selective connection between the inflation mechanism 30 and the valve mechanism 60. When the target vehicle is stationary and the tire 50 of the target vehicle needs to be inflated, the connecting mechanism 40 controls the inflation mechanism 30 to be connected with the valve mechanism 60 to inflate the tire 50 of the target vehicle. After the tire 50 of the target vehicle is inflated, the connecting mechanism 40 controls the inflation mechanism 30 to be disconnected from the valve mechanism 60; when the target vehicle is driving, the connecting mechanism 40 controls the inflation mechanism 30 to be disconnected from the valve mechanism 60.

[0059] The connection mechanism 40 may be a mechanical valve. When the tire 50 of the target vehicle needs to be inflated, the mechanical valve is opened. When the tire 50 of the target vehicle does not need to be inflated, the mechanical valve is closed.

[0060] refer to Figure 2, is a block diagram of an EMB system according to some embodiments of the present invention, wherein an EMB controller 80 is connected to a wheel-end motor 10, an air charging mechanism 30, and a connecting mechanism 40, and is used to control the connecting mechanism 40 according to the tire pressure data of the target vehicle, so that the connecting mechanism 40 controls the air charging mechanism 30 to connect with the valve mechanism 60; and drives the wheel-end motor 10, so that the wheel-end motor 10 drives the air charging mechanism 30 to inflate the tire 50 of the target vehicle through the connecting mechanism 40 and the valve mechanism 60. For example, when the tire pressure of the tire 50 of the target vehicle is lower than a certain value, the connecting mechanism 40 controls the air charging mechanism 30 to connect with the valve mechanism 60, and the wheel-end motor 10 drives the air charging mechanism 30 to inflate the tire 50 of the target vehicle through the connecting mechanism 40 and the valve mechanism 60.

[0061] Continue to refer Figure 2 The tire pressure sensor 70 is connected to the EMB controller 80, and is used to detect the tire pressure data of the tire 50 of the target vehicle in real time, and send the tire pressure data to the EMB controller 80, wherein the number of the tire pressure sensors 70 is at least four, that is, each tire 50 of the target vehicle is provided with at least one tire pressure sensor 70. Preferably, the number of the tire pressure sensors 70 is eight, that is, each tire 50 of the target vehicle is provided with two tire pressure sensors 70.

[0062] The electronic clutch 20 is connected to the EMB controller 80. The electronic clutch 20 is arranged between the wheel-end motor 10 and the inflation mechanism 30. When inflating the tire 50 of the target vehicle, the electronic clutch 20 controls the wheel-end motor 10 to combine with the inflation mechanism 30, and when the inflation mechanism 30 is connected to the valve mechanism 60, the inflation mechanism 30 can inflate the tire 50 of the target vehicle; when it is not necessary to inflate the tire 50 of the target vehicle, the electronic clutch 20 controls the wheel-end motor 10 to disengage from the inflation mechanism 30.

[0063] In some embodiments, continue to refer to Figure 2The EMB system is composed of a pedal simulator 90, an EPB (Electronic Parking Brake) switch 100, an EMB controller 80, an energy storage module 110, a wheel-end motor 10, a wiring harness 120, and a CAN (Controller Area Network) network 130. In the EMB system, the vehicle power supply 140 provides power to the energy storage module 110. The energy storage module 110 is mainly composed of supercapacitors, which store electrical energy after charging and are used to power the wheel-end motor 10 during braking. The EMB controller 80 can receive a braking demand signal from the pedal simulator 90 or a signal from the EPB switch 100 to control the wheel-end motor 10 to work. When the wheel-end motor 10 rotates, it will push the brake to work and generate braking force. In addition, the EMB controller 80 can also receive a work request signal from the outside to control the wheel-end motor 10 to work.

[0064] In summary, the EMB-based intelligent tire inflation system according to the embodiment of the present invention includes: a wheel-end motor, which is arranged correspondingly with the tire of the target vehicle; an inflation mechanism, which is arranged on the wheel-end motor; a valve mechanism, which is arranged on the tire of the target vehicle; a connecting mechanism, which is arranged between the inflation mechanism and the valve mechanism, and is used to control the selective connection between the inflation mechanism and the valve mechanism; an EMB controller, which is connected to the wheel-end motor, the inflation mechanism and the connecting mechanism, and is used to control the connecting mechanism according to the tire pressure data of the target vehicle, so that the connecting mechanism controls the inflation mechanism to connect with the valve mechanism; and a driving wheel-end motor, so that the wheel-end motor drives the inflation mechanism to inflate the tire of the target vehicle through the connecting mechanism and the valve mechanism. Thus, the system can inflate the tire of the target vehicle by driving the inflation mechanism through the wheel-end motor, and can stabilize the tire pressure of the tire within the optimal range, thereby improving the power economy, braking performance, handling and comfort of the vehicle and the tire, reducing the fuel consumption of the vehicle, reducing the wear of the tire, and reducing the risk of tire blowout.

[0065] refer to Figure 3 , is a flow chart of a control method of an EMB-based intelligent tire inflation system according to some embodiments of the present invention.

[0066] like Figure 3 As shown, the control method of the intelligent tire inflation system based on EMB according to the embodiment of the present invention may include the following steps:

[0067] S301, obtaining tire pressure data of the tires of the target vehicle.

[0068] Specifically, the tire pressure data of the target vehicle's tires can be detected by a tire pressure sensor. Alternatively, the tire pressure can be determined to be abnormal by monitoring the rotation speed and other data of the target vehicle's tires. Alternatively, the tire pressure data of the target vehicle's tires can be identified or calculated using the ABS (Anti-lock Braking System) wheel speed signal.

[0069] S302: Determine whether it is necessary to inflate the tires of the target vehicle according to the tire pressure data.

[0070] Specifically, after obtaining the tire pressure data of the target vehicle's tires, it is determined whether it is necessary to inflate the tires of the target vehicle based on the tire pressure data. For example, when the tire pressure of the target vehicle's tires is low, it is necessary to inflate the tires of the target vehicle. For another example, when the tire pressure of the target vehicle's tires is within the optimal range, it is not necessary to inflate the tires of the target vehicle.

[0071] S303, in response to the need to inflate the tires of the target vehicle, control the connecting mechanism so that the connecting mechanism controls the inflation mechanism to connect with the valve mechanism; and drive the wheel-end motor so that the wheel-end motor drives the inflation mechanism to inflate the tires of the target vehicle through the connecting mechanism and the valve mechanism.

[0072] Specifically, when it is necessary to inflate the tires of the target vehicle, it can be indicated that the tire pressure of the target vehicle's tires is low, and the connecting mechanism and the driving wheel-end motor are controlled according to the tire pressure data of the target vehicle, so that the connecting mechanism controls the inflation mechanism to connect with the valve mechanism, and the wheel-end motor drives the inflation mechanism to inflate the tires of the target vehicle through the connecting mechanism and the valve mechanism. Thus, the tires of the target vehicle can be inflated by driving the inflation mechanism through the wheel-end motor, and the tire pressure can be stabilized within the optimal range, thereby improving the power economy, braking performance, handling and comfort of the vehicle and tires, reducing the fuel consumption of the vehicle, reducing tire wear, and reducing the risk of tire blowout.

[0073] In some embodiments of the present invention, before controlling the connection mechanism and driving the wheel-end motor, the method further includes: determining whether the target vehicle is in a stationary state; in response to the target vehicle being in a stationary state, determining to control the connection mechanism and determining to drive the wheel-end motor.

[0074] Specifically, before controlling the connecting mechanism and the driving wheel-end motor, since the tires of the target vehicle can be inflated only when the target vehicle is stationary, it is necessary to judge whether the target vehicle is stationary. When the target vehicle is in the off state or the parking state, it can be indicated that the target vehicle is stationary. At this time, the connecting mechanism and the driving wheel-end motor are controlled so that the connecting mechanism controls the inflation mechanism to connect with the valve mechanism, and the wheel-end motor drives the inflation mechanism to inflate the tires of the target vehicle through the connecting mechanism and the valve mechanism.

[0075] In some embodiments of the present invention, judging whether it is necessary to inflate the tires of the target vehicle according to the tire pressure data includes: comparing the tire pressure data with a preset tire pressure threshold; and in response to the tire pressure data being lower than the preset tire pressure threshold, determining that it is necessary to inflate the tires of the target vehicle. The preset tire pressure threshold can be set according to actual conditions.

[0076] Specifically, after the tire pressure data of the target vehicle's tires is obtained, the tire pressure data of the target vehicle's tires is compared with a preset tire pressure threshold to determine whether the tire pressure data of the target vehicle's tires is lower than the preset tire pressure threshold. When the tire pressure data of the target vehicle's tires is lower than the preset tire pressure threshold, it can be indicated that the tire pressure of the target vehicle's tires is low, and it is necessary to inflate the target vehicle's tires to increase the tire pressure of the target vehicle's tires so that the tire pressure data of the target vehicle's tires is not lower than the preset tire pressure threshold. When the tire pressure data of the target vehicle's tires is not lower than the preset tire pressure threshold, it can be indicated that the tire pressure of the target vehicle's tires is within the optimal range, and it is not necessary to inflate the target vehicle's tires, which can improve the safety of the vehicle when the vehicle is driving.

[0077] In some embodiments of the present invention, the method further includes: in response to the need to inflate the tires of the target vehicle, controlling the electronic clutch so that the electronic clutch controls the wheel-end motor to combine with the inflation mechanism.

[0078] Specifically, when it is necessary to inflate the tires of the target vehicle, it may indicate that the tire pressure of the target vehicle's tires is low. At this time, the electronic clutch controls the wheel-end motor to combine with the inflation mechanism, and the connecting mechanism controls the inflation mechanism to connect with the valve mechanism, so that the inflation mechanism can inflate the tires of the target vehicle. After the inflation of the tires of the target vehicle is completed, the electronic clutch controls the wheel-end motor to disengage from the inflation mechanism, and the connecting mechanism controls the inflation mechanism to disconnect from the valve mechanism, so that the inflation mechanism stops infusing the tires of the target vehicle.

[0079] In some embodiments of the present invention, the above method also includes: in response to receiving a start signal from the target vehicle during the process of inflating the tires of the target vehicle, controlling the connecting mechanism so that the connecting mechanism controls the inflation mechanism to disconnect from the valve mechanism; and stopping driving the wheel-end motor.

[0080] Specifically, during the process of inflating the tires of the target vehicle, if a start signal of the target vehicle is received, it may indicate that the driver needs to use the vehicle, that is, the target vehicle is about to drive. In order not to affect the driver's demand for the vehicle, the connecting mechanism controls the inflation mechanism to disconnect from the valve mechanism, and the wheel-end motor stops driving the inflation mechanism to inflate the tires of the target vehicle through the connecting mechanism and the valve mechanism, and stops the inflation operation in time to avoid affecting the driver's normal driving and improve the safety of vehicle driving.

[0081] In some embodiments of the present invention, the method further includes: in response to receiving a start signal from the target vehicle during the process of inflating the tire of the target vehicle, controlling the electronic clutch so that the electronic clutch controls the wheel end motor to disengage from the inflation mechanism.

[0082] Specifically, during the process of inflating the tires of the target vehicle, if a start signal from the target vehicle is received, it means that the driver needs to use the vehicle, that is, the target vehicle is about to drive. In order not to affect the driver's demand for the vehicle, the electronic clutch controls the wheel-end motor to disengage from the inflation mechanism, and stops the inflation operation in time to avoid affecting the driver's normal driving and improve the safety of vehicle driving.

[0083] In some embodiments, a timer can be set inside the EMB controller to determine whether the time for inflating the tires of the target vehicle reaches a preset time threshold. When the time for inflating the tires of the target vehicle exceeds the preset time threshold, that is, when the tires of the target vehicle are inflated for a long time under normal operation of the inflation system, the tires of the target vehicle still cannot reach the standard tire pressure, or the inflation system fails. In this case, the tires of the target vehicle may be damaged. At this time, inflating the tires of the target vehicle is stopped, and a fault prompt of abnormal tire pressure of the target vehicle is issued on the dashboard of the target vehicle to remind the driver to repair the tires.

[0084] In other embodiments, a temperature sensor can be set on the tire of the target vehicle, and the ambient temperature of the tire can be detected by the temperature sensor. The detected ambient temperature is sent to the EMB controller, and the EMB controller sets the optimal tire pressure control target range and inflation tire pressure target of the tire of the target vehicle according to the received ambient temperature.

[0085] For example, when the tires of the target vehicle are inflated, an optical prompt will be generated in the cab of the target vehicle, such as an indicator light on the EPB switch flashing at a certain frequency.

[0086] Exemplarily, the tire pressure data of the target vehicle's tires is lower than a preset tire pressure threshold, wherein the preset tire pressure threshold is much larger than the alarm tire pressure value of the tire pressure detection system of the target vehicle's tires. For example, the preset tire pressure threshold may be 270 kPa, and the alarm tire pressure of the tire pressure detection system may be 202 kPa. When the tire pressure data of the target vehicle's tires is lower than the preset tire pressure threshold, it may indicate that the tire pressure of the target vehicle's tires is low, and the tires of the target vehicle need to be inflated; when the tire pressure data of the target vehicle's tires is lower than the alarm tire pressure value, it may indicate that the tire pressure of the target vehicle's tires is too low, and there is a serious air leak or other problem with the tires, and they need to be checked and inflated to a safe level immediately to avoid driving safety hazards.

[0087] As a specific example, Figure 4 As shown, the flowchart of the control method of the EMB-based intelligent tire inflation system of the present invention may include the following steps:

[0088] S401, a tire pressure sensor detects tire pressure data of a tire of a target vehicle.

[0089] S402, determining whether the tire pressure data of the target vehicle's tire is lower than a preset tire pressure threshold. If yes, executing step S403; if no, returning to step S401.

[0090] S403, determine whether the target vehicle is in a stationary state. If yes, execute step S404; if not, return to step S401.

[0091] S404, the electronic clutch controls the wheel end motor to be combined with the inflation mechanism.

[0092] S405, controlling the connecting mechanism and driving the wheel-end motor according to the tire pressure data of the target vehicle, so that the connecting mechanism controls the inflation mechanism to connect with the valve mechanism, and the wheel-end motor drives the inflation mechanism to inflate the tire of the target vehicle through the connecting mechanism and the valve mechanism.

[0093] Therefore, the tire pressure of the target vehicle's tire can be detected by the tire pressure sensor, and the tire pressure can be sent to the CAN network in the form of a message. The EMB controller receives the tire pressure on the CAN network and monitors whether the tire pressure is within the optimal range. When the tire pressure is detected to be lower than the preset tire pressure threshold, the EMB controller is triggered to enter the intelligent inflation mode, that is, after the vehicle is turned off and locked, the EMB controller will not immediately enter the sleep mode, but will automatically control the inflation mechanism to connect with the valve mechanism, and at the same time trigger the wheel-end motor of the EMB controller to combine with the inflation mechanism, so that the inflation mechanism inflates the tire, and after the inflation is completed, the inflation mechanism and the valve mechanism are automatically disconnected. After the automatic inflation is completed, the EMB controller enters the sleep mode.

[0094] In summary, the control method of the intelligent tire inflation system based on EMB according to the embodiment of the present invention includes: obtaining the tire pressure data of the tire of the target vehicle; judging whether it is necessary to inflate the tire of the target vehicle according to the tire pressure data; in response to the need to inflate the tire of the target vehicle, controlling the connection mechanism so that the connection mechanism controls the inflation mechanism to connect with the valve mechanism; and driving the wheel-end motor so that the wheel-end motor drives the inflation mechanism to inflate the tire of the target vehicle through the connection mechanism and the valve mechanism. Thus, the method can judge whether it is necessary to inflate the tire of the target vehicle according to the tire pressure data of the tire, and when it is necessary to inflate the tire of the target vehicle, the wheel-end motor drives the inflation mechanism to inflate the tire of the target vehicle, so that the tire pressure of the tire can be stabilized within the optimal range, thereby improving the power economy, braking performance, handling and comfort of the vehicle and the tire, reducing the fuel consumption of the vehicle, reducing the wear of the tire, and reducing the risk of tire blowout.

[0095] It should be noted that the method of the embodiment of the present invention can be performed by a single device, such as a computer or a server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other.
