Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air suspension systems, in particular, to an air suspension system temperature protection method, device, medium and electronic equipment. BACKGROUND

[0002] The air suspension system includes an air spring and a shock absorber. When the air spring and the shock absorber are designed in an integrated manner, the air spring is wrapped outside the shock absorber, resulting in poor heat dissipation effect of the shock absorber.

[0058] Figure 1 A flowchart of an air suspension system temperature protection method in the embodiments of the present application is shown, see Figure 1 An air suspension system temperature protection method is provided, the air suspension system includes an air spring and a shock absorber, the air spring is arranged outside the shock absorber, that is, the air spring is wrapped outside the shock absorber, the shock absorber includes a shock absorber electromagnetic valve controlling an oil circuit, the method includes at least S1 to S3, which are described in detail as follows:

[0059] In step S1, the real-time temperature of the coil of the shock absorber solenoid valve is monitored. When the temperature of the shock absorber rises, the temperature of the hydraulic oil in the oil passage, the shock absorber solenoid valve, and the coil of the shock absorber solenoid valve also rises, and thus the change in the temperature of the coil of the shock absorber solenoid valve can reflect the change in the temperature of the shock absorber. By monitoring the temperature of the coil of the shock absorber solenoid valve, the temperature of the shock absorber can be indirectly monitored.

[0060] In step S2, it is determined whether the real-time temperature at the first current time is greater than a first temperature threshold. If yes, it is determined whether a first duration during which the real-time temperature is greater than the first temperature threshold is greater than a first time threshold. When the real-time temperature is greater than the first temperature threshold, it indicates that the temperature of the shock absorber is high, and the first duration needs to be further determined. When the first duration is greater than the first time threshold, it indicates that the duration of the high temperature is long, and the real-time temperature of the coil of the shock absorber solenoid valve needs to be re-monitored. The first duration is a duration counted from the first current time corresponding to the time when the real-time temperature is greater than the first temperature threshold.

[0061] In some embodiments, after the determination of whether the real-time temperature at the first current time is greater than the first temperature threshold, the method further comprises: if no, returning to the step of monitoring the real-time temperature of the coil of the shock absorber solenoid valve. In step S3, if yes, it is determined whether the real-time temperature at a second current time is greater than a second temperature threshold. If yes, the air spring and the shock absorber solenoid valve are cooled, wherein the second current time is a time reached by the first duration from the first current time, and the second temperature threshold is greater than the first temperature threshold. When the real-time temperature at the second current time is greater than the second temperature threshold, it indicates that the shock absorber is overheated, and the shock absorber needs to be cooled substantially, i.e., the shock absorber is indirectly cooled by cooling the air spring and the shock absorber solenoid valve.

[0062] For example, the first current time is the 1st second, the first duration is 10 seconds, and the second current time is the 11st second.

[0063] In some embodiments, after the judging whether the real-time temperature at the second current time is greater than the second temperature threshold, further comprising: if no, judging whether the real-time temperature at the second current time is greater than a third temperature threshold, and if yes, cooling the air spring, wherein the third temperature threshold is greater than the first temperature threshold and less than the second temperature threshold. When the real-time temperature at the second current time is greater than the third temperature threshold and less than or equal to the second temperature threshold, it indicates that the shock absorber temperature is high, but not hot, and the shock absorber needs to be cooled at a small amplitude, i.e. indirectly cooling the shock absorber by cooling the air spring.

[0064] In some embodiments, after the judging whether the real-time temperature at the second current time is greater than the third temperature threshold, further comprising: if no, returning to execute the step of monitoring the real-time temperature of the coil of the electromagnetic valve of the shock absorber.

[0065] In some embodiments, after the cooling the air spring, further comprising: judging whether the real-time temperature at a third current time is less than a fourth temperature threshold, and if yes, judging whether a second duration that the real-time temperature is less than the fourth temperature threshold is greater than a second time threshold, and if yes, stopping cooling the air spring, wherein the fourth temperature threshold is less than the first temperature threshold. The fourth temperature threshold can be understood as a safety temperature threshold. When the real-time temperature at the third current time is less than the fourth temperature threshold, it indicates that the shock absorber temperature has been reduced to a safe temperature, and the shock absorber temperature is low, so the cooling of the air spring, i.e. the cooling of the shock absorber, can be stopped. The second duration is the duration since the third current time corresponding to the real-time temperature being less than the fourth temperature threshold.

[0066] In some embodiments, after the judging whether the real-time temperature at the third current time is less than the fourth temperature threshold, further comprising: if no, continuing to cool the air spring, and returning to execute the step of judging whether the real-time temperature at the third current time is less than the fourth temperature threshold.

[0067] In some embodiments, after the cooling of the air spring and the shock absorber solenoid valve, further comprising: determining whether the real-time temperature at a fourth current time is less than a fourth temperature threshold, if yes, determining whether a third duration that the real-time temperature is less than the fourth temperature threshold is greater than a second time threshold, if yes, stopping the cooling of the air spring and the shock absorber solenoid valve, wherein the fourth current time is any time of the cooling of the air spring and the shock absorber solenoid valve, and the fourth temperature threshold is less than the first temperature threshold. The fourth temperature threshold can be understood as a safety temperature threshold, when the real-time temperature at the fourth current time is less than the fourth temperature threshold, it indicates that the temperature of the shock absorber has been reduced to a safety temperature, and the cooling of the air spring and the shock absorber solenoid valve can be stopped, i.e. the cooling of the shock absorber is stopped. The third duration is a duration counted from the fourth current time corresponding to the time when the real-time temperature is less than the fourth temperature threshold.

[0068] In some embodiments, after the determination of whether the real-time temperature at the fourth current time is less than the fourth temperature threshold, further comprising: if no, continuing the cooling of the air spring and the shock absorber solenoid valve, and returning to the step of determining whether the real-time temperature at the fourth current time is less than the fourth temperature threshold.

[0069] In some embodiments, the cooling of the air spring and the shock absorber solenoid valve comprises: discharging gas from the air spring, and supplementing gas to the air spring, wherein the temperature of the supplemented gas is lower than the temperature of the discharged gas; and controlling the working current of the shock absorber solenoid valve to be a minimum working current, so as to minimize the heat generated by the shock absorber solenoid valve when working.

[0070] In some embodiments, the cooling of the air spring comprises: discharging gas from the air spring, and supplementing gas to the air spring, wherein the temperature of the supplemented gas is lower than the temperature of the discharged gas. The air spring is cooled by discharging high-temperature gas and supplementing low-temperature gas.

[0071] In some embodiments, when the air spring is supplemented with gas, normal-temperature gas can be supplemented.

[0072] In some embodiments, the discharging of gas from the air spring and the supplementing of gas to the air spring comprises: obtaining a first gas flow rate, discharging gas from the air spring at the first gas flow rate, and supplementing gas to the air spring at the first gas flow rate. The discharging rate of the gas is equal to the supplementing rate of the gas, so as to keep the amount of gas in the air spring unchanged.

[0073] In some embodiments, the discharging gas from the air spring and the supplementing gas to the air spring comprises: discharging gas from the air spring at a maximum discharging rate and supplementing gas to the air spring at a maximum supplementing rate. The air spring is cooled at a maximum amplitude by the maximum amplitude of the ventilation rate, and the cooling efficiency is improved.

[0074] In some embodiments, the discharging gas from the air spring and the supplementing gas to the air spring comprises: obtaining a target relationship representing the relationship between the temperature difference and the gas flow rate, determining a first difference between the real-time temperature at the second current time and the second temperature threshold, determining the second gas flow rate according to the first difference and the target relationship, discharging gas from the air spring at the second gas flow rate, and supplementing gas to the air spring at the second gas flow rate.

[0075] In some embodiments, for the target relationship, the greater the temperature difference, the greater the gas flow rate.

[0076] In some embodiments, the monitoring the real-time temperature of the shock absorber solenoid valve coil comprises: obtaining a real-time current and a real-time voltage of the coil of the shock absorber solenoid valve; determining a real-time resistance of the coil of the shock absorber solenoid valve according to the real-time current and the real-time voltage; and determining the real-time temperature according to the real-time resistance.

[0077] In some embodiments, the determining the real-time temperature according to the real-time resistance comprises: obtaining a preset relationship table representing the relationship between the resistance and the temperature of the coil of the shock absorber solenoid valve; and determining the real-time temperature according to the real-time resistance and the preset relationship table. The resistance changes when the temperature of the coil changes, so the temperature corresponding to the resistance can be obtained according to the preset relationship table. The preset relationship table can be obtained by a curve of resistance versus temperature or by calibration.

[0078] Exemplarily, the first temperature threshold is 80℃, the second temperature threshold is 120℃, the third temperature threshold is 100℃, the fourth temperature threshold is 60℃, the first time threshold is 1s, and the second time threshold is 3s.
