Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein.

[0030] The first aspect of the present application provides a vehicle tire pressure control method, Figure 1 1 is a flow chart of an embodiment of a vehicle tire pressure control method provided by the present application. Figure 1 , the method comprises the following steps:

[0031] S101: If the vehicle is in driving state, the current working state of the vehicle, the current driving condition of the road on which the vehicle is driving, and the current environmental state of the environment in which the vehicle is located are obtained.

[0032] When a vehicle is in motion, the tire pressure of the vehicle has a certain influence on the driving of the vehicle. The present application can ensure that the vehicle has a suitable tire pressure by adjusting the tire pressure when the vehicle is in motion, so as to ensure that the vehicle has a good driving state.

[0033] The current working state of the vehicle refers to the working state of the vehicle at the current moment, that is, the specific operating state of the vehicle at the current moment. For example, it may include the vehicle's operating speed, driving mode, etc. The current driving section of the road on which the vehicle is traveling, that is, the driving conditions of the road on which the vehicle is traveling at the current moment. For example, it may include the straight road and curve type, uphill and downhill type, etc. The current environmental state of the vehicle, that is, the environmental state of the environment in which the vehicle is currently located. For example, the environmental state may include ambient temperature, humidity, and air pressure, etc.

[0034] It should be understood that when a vehicle is in different working states, the requirements for the tire pressure of the vehicle are generally different. Therefore, the current working state of the vehicle specifically reflects the tire pressure required by the vehicle at the current moment. The current driving road condition and the current environmental state reflect the specific driving environment of the vehicle. In different driving environments, the vehicle generally requires different tire pressures.

[0035] S102: If it is detected that any one or more of the current working state, the current driving road condition and the current environmental state has a change of a preset change type, a corresponding tire pressure adjustment amount is determined according to the preset change type generated by the change.

[0036] The current working state, the current driving road condition and the current environment state are respectively provided with preset change types, and the preset change type is a change type from one state to another state. For example, for the working state of the vehicle, two different working states can be set, and the change type from one working state to another working state is used as a preset change type.

[0037] It should be understood that during driving, the current working state, the current driving road condition and the current environmental state may change at any time, but sometimes the changes are relatively small, and such relatively small changes generally do not require changing the tire pressure. Therefore, the present application will only determine the tire pressure adjustment amount when at least one of the three changes into a preset change type.

[0038] Among them, a correspondence between a preset change type and a tire pressure adjustment amount can be established, and then when the preset change type occurs, the corresponding tire pressure adjustment amount is determined through the correspondence. Among them, when determining the corresponding tire pressure adjustment amount according to the preset change type generated by the changer, if there is only one changer, then the corresponding tire pressure adjustment amount is determined only according to the preset change type corresponding to this changer. If there are multiple changers, then the corresponding tire pressure adjustment amounts are determined according to the preset change types corresponding to the multiple changers.

[0039] S103: taking the sum of the current tire pressure of the vehicle and the tire pressure adjustment amount as the target tire pressure, and adjusting the tire pressure of the vehicle to the target tire pressure.

[0040] After the tire pressure adjustment amount is determined, this step uses the sum of the current tire pressure and the tire pressure adjustment amount as the target tire pressure, and adjusts the vehicle tire pressure to the target tire pressure, thereby adjusting the tire pressure through the tire pressure adjustment amount. The tire pressure adjustment amount can be a positive value or a negative value. When the tire pressure adjustment amount is a positive value, the tire pressure will be increased, and when the tire pressure adjustment amount is a negative value, the tire pressure will be decreased.

[0041] In summary, based on the vehicle tire pressure control method provided in this application, the vehicle's tire pressure can be adjusted according to the vehicle's working status, driving road conditions and environmental conditions, thereby being able to meet the actual needs of the vehicle for tire pressure during actual driving, thereby ensuring the vehicle's driving safety and efficiency.

[0042] Figure 2 It is a flow chart of another embodiment of the vehicle tire pressure control method provided in the present application.

[0043] Combination Figure 2 In some specific embodiments, when it is detected that any one or more of the current working state, the current driving road condition and the current environmental state has a change of a preset change type, the step of determining the corresponding tire pressure adjustment amount according to the preset change type generated by the change, that is, the above-mentioned step S102, includes:

[0044] S201: When a preset change type is detected in any two or three of the current working state, the current driving road condition and the current environmental state, corresponding tire pressure adjustment amounts are determined according to the preset change types corresponding to the changes.

[0045] It should be understood that among the current working state, the current driving road condition and the current environmental state, one of them may change, or multiple of them may change at the same time. When one of them changes, the tire pressure adjustment amount can be directly determined according to the preset change type corresponding to the one. When multiple changes occur, the corresponding tire pressure adjustment amounts can be determined according to the preset change types corresponding to the multiple changes, and then the final tire pressure adjustment amount can be determined according to these tire pressure adjustment amounts in the subsequent process.

[0046] S202: Perform weighted calculation on each tire pressure adjustment amount, and use the sum of all weighted calculated tire pressure adjustment amounts as the tire pressure adjustment amount; wherein the tire pressure adjustment amounts corresponding to the current working state, the current driving road condition, and the current environmental state correspond to different weighted values.

[0047] When multiple changes occur, since the multiple changers may affect each other, in order to reduce the mutual impact, the present application will not simply add the tire pressure adjustment amounts corresponding to the multiple changers as the final tire pressure adjustment amount, but will weight each tire pressure adjustment amount separately, and then add the weighted tire pressure adjustment amounts to obtain the final tire pressure adjustment amount.

[0048] Among them, the tire pressure adjustment amounts corresponding to the current working state, the current driving road condition and the current environmental state correspond to different weighted values, that is, the current working state, the current driving road condition and the current environmental state correspond to different weighted values.

[0049] Among them, when setting the weighted value, it can be set according to the degree of influence of each on the required tire pressure when the current working state, the current driving road condition and the current environmental state all change. For example, when the current working state and the current driving road condition change, if the change in the current working state has a greater impact on the required tire pressure, then the weighted value of the current working state can be set to be larger. For example, when the current working state and the current driving road condition change, the weighted value corresponding to the current working state is directly set to weighted value A, and the tire pressure adjustment amount corresponding to all preset change types of the current working state corresponds to weighted value A. The weighted value corresponding to the current driving road condition is set to weighted value B, and the tire pressure adjustment amount corresponding to all preset change types corresponding to the current driving road condition corresponds to weighted value B.

[0050] For a more specific setting method of the weighted value, different weighted values ​​can be set for different combinations of preset change types. For example, when the current working state and the current driving road condition change, if the current working state changes from the first working state to the second working state, the current driving road condition changes from the first driving road condition to the second driving road condition. For this combination of preset change types, the weighted value corresponding to the change from the first working state to the second working state can be set to the first weighted value, and the weighted value corresponding to the change from the first driving road condition to the second driving road condition can be set to the second weighted value. If the previous working state changes from the first working state to the third working state, the current driving road condition changes from the first driving road condition to the second driving road condition. For this combination of preset change types, the weighted value corresponding to the change from the first working state to the third working state can be set to the third weighted value, and the weighted value corresponding to the change from the first driving road condition to the second driving road condition can be set to the fourth weighted value.

[0051] Figure 3 It is a flow chart of another embodiment of the vehicle tire pressure control method provided in the present application.

[0052] The following embodiment provides a method for determining the tire pressure adjustment amount when one of them changes. If multiple factors change, the tire pressure adjustment amount corresponding to one of them can also be determined by the following embodiment, and then the final tire pressure change amount can be determined according to the weighted method when multiple factors change in the above embodiment.

[0053] Combination Figure 3 In some specific embodiments, the driving road condition includes a curved road condition and a slope road condition; when it is detected that any one or more of the current working state, the current driving road condition and the current environmental state undergoes a change of a preset change type, a step of determining a corresponding tire pressure adjustment amount according to the preset change type generated by the change, i.e., the above-mentioned step S102, includes:

[0054] S301: Detecting that the current driving road condition changes to a preset curved road condition, determining a first tire pressure adjustment amount according to the preset curved road condition; wherein the first tire pressure adjustment amount is a positive value.

[0055] At this time, the current driving condition changes to the preset curved road condition, that is, the historical driving condition changes from the non-preset curved road condition to the current driving condition of the preset curved road condition, corresponding to the preset change type of the non-preset curved road condition to the preset curved road condition. Among them, the specific parameters of the preset curved road condition can be specifically set, for example, the curvature and length of the curve can be preset.

[0056] The first tire pressure adjustment amount is determined according to the preset curved road condition, that is, the first tire pressure adjustment amount is determined according to the preset change type of the non-preset curved road condition to the preset curved road condition. At this time, the first tire pressure adjustment amount is a positive value, so that the tire pressure of the vehicle is increased, thereby meeting the tire pressure requirement of the vehicle passing through the preset curved road condition.

[0057] In some application scenarios, the first tire pressure adjustment amount may be 1-2 psi, where 1 psi = 6.895 kPa = 0.0689476 bar = 0.006895 MPa.

[0058] S302: When it is detected that the current driving road condition changes to a preset slope road condition, a second tire pressure adjustment amount is determined according to the preset slope road condition; wherein, when the preset slope road condition is an uphill road condition, the second tire pressure adjustment amount is a positive value, and when it is a downhill road condition, the second tire pressure adjustment amount is a negative value.

[0059] At this time, the preset change type is the change from the non-preset slope road condition to the preset slope road condition. The second tire pressure adjustment amount is determined according to the preset slope road condition, that is, the second tire pressure adjustment amount is determined according to the preset change type from the non-preset slope road condition to the preset slope road condition.

[0060] The specific parameters of the preset slope road conditions can be specifically set. For example, for an uphill road, the average slope is above 3% and the length is more than 2 km. For a downhill road, the average slope is above -3% and the length is more than 2 km.

[0061] When the preset slope road condition is an uphill road condition, a higher tire pressure is required, so the second tire pressure adjustment amount is set to a positive value, which can be set to 2-3psi. When the preset slope road condition is a downhill road condition, a lower tire pressure is required, so the second tire pressure adjustment amount is set to a negative value, which can be set to -3--2psi.

[0062] S303: When it is detected that the current driving road condition changes to a preset curved road condition and a preset slope road condition at the same time, the product of the first tire pressure adjustment amount and the first preset weighted value and the product of the second tire pressure adjustment amount and the second preset weighted value are added together to obtain a third tire pressure adjustment amount.

[0063] It should be understood that in the above steps S301 and S302, the first tire pressure adjustment amount and the second tire pressure adjustment amount can be determined respectively for the case where the current driving road condition only changes to the preset slope road condition, or the current driving road condition only changes to the preset slope road condition.

[0064] For the simultaneous transformation into the preset curved road condition and the preset slope road condition, that is, the preset change type of the non-preset curved road condition transforming into the preset curved road condition, and the preset change type of the non-preset slope road condition transforming into the preset slope road condition. This application does not directly add the first tire pressure adjustment amount and the second tire pressure adjustment amount as the final tire pressure adjustment amount, but weights the first tire pressure adjustment amount and the second tire pressure adjustment amount respectively to obtain the third tire pressure adjustment amount.

[0065] At this time, the preset change type of the non-preset curved road condition changing to the preset curved road condition corresponds to the first preset weighted value, and the preset change type of the non-preset slope road condition changing to the preset slope road condition corresponds to the second preset weighted value.

[0066] Figure 4 It is a flow chart of another embodiment of the vehicle tire pressure control method provided in the present application.

[0067] Combination Figure 4 In some specific embodiments, the working state includes the vehicle driving mode and the vehicle speed; when it is detected that any one or more of the current working state, the current driving road condition and the current environmental state has a change of a preset change type, the step of determining the corresponding tire pressure adjustment amount according to the preset change type generated by the change, that is, the above-mentioned step S102, includes:

[0068] S401: Detecting that the current working state changes from the first driving mode to the second driving mode, determining a fourth tire pressure adjustment amount according to the second driving mode.

[0069] It should be understood that different driving modes may correspond to different tire pressures, and the change from the first driving mode to the second driving mode is a preset change type. At this time, determining the fourth tire pressure adjustment amount according to the second driving mode means determining the corresponding fourth tire pressure adjustment amount according to the preset change type from the first driving mode to the second driving mode.

[0070] S402: When it is detected that the current working state changes to a preset high vehicle speed, a fifth tire pressure adjustment amount is determined according to the high vehicle speed; wherein the fifth tire pressure adjustment amount is a positive value.

[0071] At this time, the vehicle speed changes from the non-preset high speed to the preset high speed, which is the preset change type. The fifth tire pressure adjustment amount is determined according to the high speed, that is, the fifth tire pressure adjustment amount is determined according to the preset change type from the non-preset high speed to the preset high speed.

[0072] When the vehicle changes from a lower speed to a higher speed, a higher tire pressure is required, so the fifth tire pressure adjustment amount is set to a positive value.

[0073] In some application scenarios, the preset high vehicle speed may be a vehicle speed greater than or equal to 100 km / h and maintained for a certain period of time, and the fifth tire pressure adjustment amount may be 1-2 psi.

[0074] S403: When it is detected that the current working state is simultaneously changed to the second driving mode and the preset high vehicle speed, the product of the fourth tire pressure adjustment amount and the third preset weighted value and the product of the fifth tire pressure adjustment amount and the fourth preset weighted value are added to obtain the sixth tire pressure adjustment amount.

[0075] It should be understood that the above steps S401 and S402 are both describing the method of determining the tire pressure adjustment amount when one type of preset change occurs. In this embodiment, the method of determining the tire pressure adjustment amount when the above two types of preset changes occur at the same time is described.

[0076] When the preset change type from the first driving mode to the second driving mode and the preset change type from the non-preset high vehicle speed to the preset high vehicle speed occur at the same time, we will weight the fourth tire pressure adjustment amount and the fifth tire pressure adjustment amount respectively and add them together to obtain the sixth tire pressure adjustment amount.

[0077] Figure 5 It is a flow chart of another embodiment of the vehicle tire pressure control method provided in the present application.

[0078] Combination Figure 5In some specific embodiments, the environmental state includes air temperature and air pressure; when it is detected that any one or more of the current working state, the current driving road condition and the current environmental state undergoes a change of a preset change type, a step of determining a corresponding tire pressure adjustment amount according to the preset change type produced by the change, i.e., the above-mentioned step S102, includes:

[0079] S501: When it is detected that the current environmental state changes to a preset temperature range, the seventh tire pressure adjustment amount is determined according to the preset temperature range; wherein, when the preset temperature range is a preset high temperature range, the seventh tire pressure adjustment amount is a negative value, and when the preset temperature range is a preset low temperature range, the seventh tire pressure adjustment amount is a positive value.

[0080] At this time, the preset change type is that the ambient temperature changes from a non-preset temperature range to a preset temperature range, and the seventh tire pressure adjustment amount is determined according to the preset temperature range, that is, the seventh tire pressure adjustment amount is determined according to the preset change type from the non-preset temperature range to the preset temperature range.

[0081] If the preset change type is from a non-preset high temperature range to a preset high temperature range, the seventh tire pressure adjustment amount is determined to be a negative value. If the preset change type is from a non-preset low temperature range to a preset low temperature range, the seventh tire pressure adjustment amount is determined to be a positive value.

[0082] In some application scenarios, when the preset temperature range is a preset high temperature range, the seventh tire pressure adjustment amount may be -2--1 psi; when the preset temperature range is a preset low temperature range, the seventh tire pressure adjustment amount may be 1-2 psi.

[0083] S502: Detecting that the current environmental state changes to a preset low pressure range, determining an eighth tire pressure adjustment amount according to the preset low pressure range; wherein the eighth tire pressure adjustment amount is a negative value.

[0084] At this time, the preset change type is that the atmospheric pressure is in a non-preset low pressure range and changes to a preset low pressure range. At this time, the tire pressure needs to be reduced, and then the eighth tire pressure adjustment amount is set to a negative value. Among them, the current environmental state changes to the preset low pressure range, generally when the vehicle travels from a non-plateau area to a plateau area, causing the altitude to increase and cause low pressure.

[0085] S503: When it is detected that the current environmental state changes to the preset temperature range and the preset low pressure range at the same time, the product of the seventh tire pressure adjustment amount and the fifth preset weighted value and the product of the eighth tire pressure adjustment amount and the sixth preset weighted value are added to obtain the ninth tire pressure adjustment amount.

[0086] When the preset change type from the non-preset temperature range to the preset temperature range and the non-preset low pressure range to the preset low pressure range occur at the same time, the seventh tire pressure adjustment amount and the eighth tire pressure adjustment amount are weighted and added to obtain the ninth tire pressure adjustment amount.

[0087] Figure 6 It is a flow chart of another embodiment of the vehicle tire pressure control method provided in the present application.

[0088] Combination Figure 6 In some specific embodiments, the environmental state includes preset rainy and snowy weather; if it is detected that any one or more of the current working state, the current driving road condition and the current environmental state has a change of a preset change type, the step of determining the corresponding tire pressure adjustment amount according to the preset change type generated by the change, that is, the above-mentioned step S102, includes:

[0089] S601: When it is detected that the current environmental state changes to the preset rainy and snowy weather state, the current driving torque of the vehicle is obtained, and when the current driving torque is lower than the preset value, the wheel speed difference of the vehicle is obtained.

[0090] Among them, the sensor on the vehicle can be used to detect whether the vehicle is currently in the preset rainy and snowy weather. When in the preset rainy and snowy weather, the vehicle is prone to slipping and causing certain dangers.

[0091] When the vehicle is skidding, the phenomenon can be alleviated by reducing the current braking torque of the vehicle. If it is detected that the current braking torque is lower than the preset value, it means that the skidding phenomenon cannot be further alleviated by reducing the torque. At this time, the wheel speed difference of the vehicle is further obtained to further determine whether the vehicle's skidding phenomenon is serious.

[0092] S602: If the wheel speed difference is higher than the preset wheel speed difference, determine the tenth tire pressure adjustment amount according to the preset rainy and snowy weather conditions; wherein the tenth tire pressure adjustment amount is a negative value.

[0093] If the wheel speed difference is higher than the preset wheel speed difference, it means that the vehicle's skidding phenomenon is still relatively serious and the phenomenon cannot be further alleviated by reducing the braking torque at this time.

[0094] At this time, the present application reduces the tire pressure by adjusting the tenth tire pressure with a negative value, thereby effectively reducing the skidding phenomenon of the vehicle. The preset rainy and snowy weather corresponds to the tenth tire pressure adjustment amount, and the severity of the preset weather can correspond to different tenth tire pressure adjustment amounts.

[0095] Figure 7 It is a flow chart of another embodiment of the vehicle tire pressure control method provided in the present application.

[0096] Combination Figure 7In some specific embodiments, the working state includes a preset acceleration state and a preset deceleration state; when it is detected that any one or more of the current working state, the current driving road condition and the current environmental state undergoes a change of a preset change type, the step of determining the corresponding tire pressure adjustment amount according to the preset change type generated by the change, i.e., the above-mentioned step S102, includes:

[0097] S701: Detecting that the current working state is changed to a preset acceleration state or a preset deceleration state, obtaining the number of slips occurring during the acceleration process or the number of slips occurring during the deceleration process.

[0098] During the acceleration of the vehicle, the vehicle is prone to slipping, and during the deceleration of the vehicle, the vehicle is prone to sliding. Both slipping and sliding are not conducive to the safe driving of the vehicle.

[0099] In this embodiment, when the vehicle is in a preset acceleration state, the number of slips occurring during the acceleration process is obtained, and when the vehicle is in a preset deceleration state, the number of slips occurring during the deceleration process is obtained, and then the real-time state of the vehicle is understood through the number of slips or slips.

[0100] S702: If the number of slips or the number of slides is greater than a preset number, determining an eleventh tire pressure adjustment amount according to a preset acceleration state or a preset deceleration state; wherein the eleventh tire pressure adjustment amount is a negative value.

[0101] During a certain acceleration process, if the number of slips is greater than a preset number, it means that the slip phenomenon of the vehicle during the acceleration process is relatively serious. At this time, the tire pressure is reduced by the eleventh tire pressure adjustment amount of a negative value, thereby reducing the slip phenomenon of the vehicle.

[0102] During a certain deceleration process, if the number of slippages is greater than a preset number, it means that the slippage of the vehicle during the deceleration process is relatively serious. At this time, the tire pressure is reduced by the eleventh tire pressure adjustment amount of a negative value, thereby reducing the slippage of the vehicle.
