[0024] Reversible valve: the reversible valve of the present embodiment is a reversible proportional valve with mechanical stop. The reversible proportional valve with mechanical stop is a valve that realizes position limiting through mechanical structure, and its core feature is to set fixed blocks or limiting devices on the valve core movement track to ensure that the reversing action stops accurately at the preset position.

[0025] Please refer to Figure 1 , Figure 1 is a step flowchart of an embodiment of the life evaluation method of the reversible valve of the present application. The order of the steps in the flowchart can be changed according to different needs, and some steps can be omitted.

[0026] It should be noted that the life evaluation method of the reversible valve of the embodiments of the present application can be applied in a vehicle driving scenario, and the execution subject can be a life evaluation device of the reversible valve, for example, during the driving of the vehicle, the life evaluation device of the reversible valve can be used to evaluate the life of the reversible valve installed in the vehicle. Of course, the life evaluation method of the reversible valve can also be applied to other scenarios that need to evaluate the life of the reversible valve, and the present application does not make specific limitations thereto.

[0027] The specific process of the present embodiment is shown in Figure 1 , including the following steps: S101, in the working process of the reversible valve, the valve plate opening of the reversible valve is collected every predetermined period.

[0028] In some embodiments, the predetermined period can be set according to actual needs, and the present embodiment does not make specific limitations on the size of the predetermined period. In some embodiments, the valve plate opening of the reversible valve is collected through the vehicle-mounted ECU.

[0029] S102, according to the valve plate openings collected in three consecutive predetermined periods, it is detected whether the reversible valve is in reversing motion or unidirectional motion.

[0030] In some embodiments, whether the reversible valve is in a reversing motion or a one-way motion is detected by: calculating a first difference value between a first valve disc opening collected in a current preset period and a second valve disc opening collected in a last preset period; calculating a second difference value between the second valve disc opening and a third valve disc opening collected in a last-but-one preset period; calculating a product of the first difference value and the second difference value, and detecting that the reversible valve is in the reversing motion if the product is less than 0, and detecting that the reversible valve is in the one-way motion if the product is greater than or equal to 0.

[0031] Specifically, the valve disc openings at the three time points are recorded , , The valve disc openings at the three time points are recorded , , It can be understood that is a current time point, is a time point in a last cycle of the current time point, is a time point in a last-but-one cycle of the current time point. The calculation and determination are as follows: If yes, it is determined that the reversible valve is in the reversing motion; otherwise, it is determined that the reversible valve is in the one-way motion.

[0032] S103, determining a total number of one-way motions and a total number of reversing motions of the reversible valve in a working process of the reversible valve.

[0033] In some embodiments, in the working process of the reversible valve, the vehicle-mounted ECU collects the valve disc opening of the reversible valve every preset period, and detects whether the reversible valve is in the reversing motion or the one-way motion according to the foregoing calculation method. The vehicle-mounted ECU records the total number of one-way motions and the total number of reversing motions.

[0034] S104, calculating a remaining service life of the reversible valve according to the total number of one-way motions, a preset one-way motion loss coefficient, the total number of reversing motions, and a preset reversing motion loss coefficient.

[0035] In some embodiments, the remaining service life is calculated according to the following formula: ; wherein S is the remaining service life, a starting life of the reversible valve is 1, is the total number of reversing motions, is the total number of one-way motions, is the reversing motion loss coefficient, is the one-way motion loss coefficient, is a maximum motion total number of the reversible valve in a reciprocating motion between a minimum opening and a maximum opening under the premise of ensuring control accuracy.

[0036] In some embodiments, the one-way motion loss coefficient is less than the commutation motion loss coefficient , and the one-way motion loss coefficient and the commutation motion loss coefficient sum to 1.

[0037] It can be understood that the commutating valve of the present embodiment is a commutating proportional valve with a mechanical stop point. This type of valve can be artificially divided into two cases during motion, one-way motion and commutation motion. The commutating valve with a mechanical stop point has a certain impact on the mechanical stop point during commutation and causes a certain amount of wear. In addition, the greater the motion stroke within a unit motion time, the stronger the impact, and there is also a certain loss to the mechanical friction pair. The one-way motion mainly considers the loss to the mechanical friction pair. Therefore, the one-way motion loss coefficient is set to be less than the commutation motion loss coefficient , so that the life evaluation method of the commutating valve of the present embodiment is more in line with the actual working condition of the commutating valve, and the accuracy of the life evaluation of the commutating valve is further improved.

[0038] In some embodiments, the one-way motion loss coefficient and the commutation motion loss coefficient can be determined in the following manner: two brand new commutating valves are taken out, which are commutating valve 1 and commutating valve 2. Commutating valve 1 repeatedly performs one-way motion, and the total number of one-way motions is recorded until the commutating valve 1 is damaged or cannot guarantee control accuracy, which is assumed to be 600 times. Commutating valve 2 repeatedly performs commutation motion, and the total number of commutation motions is recorded until the commutating valve 2 is damaged or cannot guarantee control accuracy, which is assumed to be 400 times. Then, according to the ratio of 600 times to 400 times, the one-way motion loss coefficient is set to 0.4, and the commutation motion loss coefficient is set to 0.6.

[0039] Compared with the related art, the present embodiment has at least the following advantages: by collecting the valve plate opening of the commutating valve every preset period, the specific motion type of the commutating valve can be detected according to the valve plate openings collected in three consecutive preset periods, and then the total number of one-way motions and the total number of commutation motions of the commutating valve during work can be determined. Since the mechanical wear degree of the commutating valve is different when the commutating valve performs one-way motion or commutation motion, by setting the one-way motion loss coefficient and the commutation motion loss coefficient, and then according to the total number of one-way motions and the one-way motion loss coefficient, and the total number of commutation motions and the commutation motion loss coefficient, the remaining service life of the commutating valve can be accurately calculated, which realizes the evaluation of the life of the commutating valve after the commutating valve works, and the accuracy of the evaluation is high.

[0040] Please refer to Figure 2 , Figure 2 is a step flow chart of an embodiment of the life evaluation method of the reversible valve of the present application. The order of the steps in the flow chart can be changed according to different needs, and some steps can be omitted. The life evaluation method of the reversible valve can be applied to the life evaluation device of the reversible valve described above, but is not limited thereto, and the embodiments of the present application do not limit this.

[0041] The present embodiment is a further improvement of the foregoing embodiments, and the main improvement is that in the present embodiment, the degree of movement of the reversible valve is also distinguished, and different movement loss coefficients are set based on different degrees of movement. In this way, the accuracy of the life evaluation of the reversible valve can be further improved.

[0042] The specific process of the present embodiment is shown in Figure 2 , including the following steps: S201, during the operation of the reversible valve, the valve plate opening of the reversible valve is collected every predetermined period.

[0043] S202, according to the valve plate openings collected in three consecutive predetermined periods, it is detected whether the reversible valve is performing a reversing movement or a one-way movement.

[0044] S203, in the case where it is detected that the reversible valve is performing a reversing movement, it is detected whether the absolute value of the second difference is greater than a first preset threshold.

[0045] Specifically, the second difference is the difference between the second valve plate opening of the foregoing embodiment and the third valve plate opening collected in the previous predetermined period.

[0046] It can be understood that the size of the first preset threshold is not specifically limited in the present embodiment and can be set according to actual needs.

[0047] S204, in the case where the reversible valve is performing a reversing movement, the first total number of times when the absolute value of the second difference is greater than the first preset threshold is determined, and the second total number of times when the absolute value of the second difference is less than or equal to the first preset threshold is determined.

[0048] Specifically, during the operation of the reversible valve, after the vehicle-mounted ECU detects that the reversible valve is performing a reversing movement each time, the vehicle-mounted ECU compares the absolute value of the second difference with the first preset threshold, in the case where the absolute value of the second difference is greater than the first preset threshold, the first total number of times is incremented by 1, and in the case where the absolute value of the second difference is less than or equal to the first preset threshold, the second total number of times is incremented by 1. It can be understood that for a brand new reversible valve, the initial values of the first total number of times and the second total number of times are both 0.

[0049] S205, in the case of detecting that the reversible valve is in unidirectional motion, detecting whether the absolute value of the second difference is greater than a second preset threshold value.

[0050] It can be understood that the embodiment does not specifically limit the size of the first preset threshold value, which can be set according to actual needs.

[0051] S206, determining the first total number of times that the absolute value of the second difference is greater than the second preset threshold value and the second total number of times that the absolute value of the second difference is less than or equal to the second preset threshold value in the case of unidirectional motion of the reversible valve.

[0052] Specifically, in the working process of the reversible valve, after the vehicle-mounted ECU detects that the reversible valve is in unidirectional motion each time, the vehicle-mounted ECU compares the absolute value of the second difference with the second preset threshold value, in the case of the absolute value of the second difference being greater than the second preset threshold value, the first total number of times is incremented by 1, and in the case of the absolute value of the second difference being less than or equal to the second preset threshold value, the second total number of times is incremented by 1. It can be understood that for a brand new reversible valve, the initial values of the first total number of times and the second total number of times are both 0.

[0053] S207, calculating the remaining service life according to the first total number of times and the first unidirectional motion loss coefficient, the second total number of times and the second unidirectional motion loss coefficient, the first total number of times of reversing and the first reversing motion loss coefficient, and the second total number of times of reversing and the second reversing motion loss coefficient.

[0054] In some embodiments, the remaining service life is calculated according to the following formula: ; Wherein S is the remaining service life, the initial life of the reversible valve is 1, is the first total number of times of reversing, is the second total number of times of reversing, is the first total number of times of unidirectional motion, is the second total number of times of unidirectional motion, is the first reversing motion loss coefficient, is the second reversing motion loss coefficient, is the first unidirectional motion loss coefficient, is the second unidirectional motion loss coefficient, is the maximum total number of times of motion of the reversible valve between the minimum opening and the maximum opening under the premise of ensuring control accuracy.

[0055] It is worth noting that the first reversing motion loss coefficient is greater than the second reversing motion loss coefficient , the first unidirectional motion loss coefficient greater than the second one-way motion loss coefficient The greater the change in the opening of the reversible valve, the stronger the loss to the friction pair and the stronger the impact on the mechanical stop point. Therefore, through such a setting, the service life evaluation method of the reversible valve of the present embodiment can be more in line with the actual working conditions of the reversible valve, further improving the accuracy of the service life evaluation of the reversible valve.

[0056] Compared with the related art, the embodiments of the present application have at least the following advantages: by collecting the valve plate opening of the reversible valve every other preset period, the specific motion type of the reversible valve can be detected according to the valve plate openings collected in three consecutive preset periods, and then the total number of one-way motions and the total number of reversing motions of the reversible valve during the working process can be determined. Since the degree of mechanical wear of the reversible valve is different when the reversible valve is in one-way motion or reversing motion, by setting the one-way motion loss coefficient and the reversing motion loss coefficient, and then according to the total number of one-way motions and the one-way motion loss coefficient, and the total number of reversing motions and the reversing motion loss coefficient, the remaining service life of the reversible valve can be accurately calculated, realizing the evaluation of the service life of the reversible valve after the reversible valve is working, and the accuracy of the evaluation is high.
