Description

Background Art

[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.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0057] Figure 1 A flow chart of a method for protecting the temperature of an air suspension system in an embodiment of the present application is shown. Figure 1 , a temperature protection method for an air suspension system is provided, the air suspension system comprises 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 comprises a shock absorber solenoid valve for controlling an oil circuit, the method comprises at least S1 to S3, which are described in detail as follows:

[0058] In step S1, the real-time temperature of the coil of the shock absorber solenoid valve is monitored. When the shock absorber temperature rises, the temperature of the hydraulic oil in the oil circuit, the shock absorber solenoid valve, and the coil of the shock absorber solenoid valve rises accordingly. Therefore, the change in the temperature of the coil of the shock absorber solenoid valve can reflect the change in the shock absorber temperature. By monitoring the temperature of the coil of the shock absorber solenoid valve, the shock absorber temperature can be indirectly monitored.

[0059] In step S2, it is determined whether the real-time temperature at the first current moment is greater than the first temperature threshold. If so, it is determined whether the first duration of the real-time temperature being greater than the first temperature threshold is greater than the first time threshold. When the real-time temperature is greater than the first temperature threshold, it indicates that the shock absorber temperature is high and it is necessary to further determine the first duration. When the first duration is greater than the first time threshold, it indicates that the high temperature lasts for a long time and it is necessary to re-monitor the real-time temperature of the coil of the shock absorber solenoid valve. The first duration is the duration starting from the first current moment corresponding to when the real-time temperature is greater than the first temperature threshold.

[0060] In some embodiments, after determining whether the real-time temperature at the first current moment is greater than the first temperature threshold, the method further includes: if not, returning to the step of monitoring the real-time temperature of the coil of the shock absorber solenoid valve. In step S3, if yes, determining whether the real-time temperature at the second current moment is greater than the second temperature threshold, and if yes, cooling the air spring and the shock absorber solenoid valve, wherein the second current moment is a moment reached after the first duration based on the first current moment, and the second temperature threshold is greater than the first temperature threshold. When the real-time temperature at the second current moment is greater than the second temperature threshold, it indicates that the shock absorber is overheated and needs to be cooled significantly, that is, the shock absorber is cooled indirectly by cooling the air spring and the shock absorber solenoid valve.

[0061] Exemplarily, the first current moment is the 1st second, the first duration is 10 seconds, and the second current moment is the 11th second.

[0062] In some embodiments, after determining whether the real-time temperature at the second current moment is greater than the second temperature threshold, the method further includes: if not, determining whether the real-time temperature at the second current moment is greater than a third temperature threshold, and if so, 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 moment 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 very high but not overheated, and the shock absorber needs to be cooled slightly, that is, the shock absorber is cooled indirectly by cooling the air spring.

[0063] In some embodiments, after determining whether the real-time temperature at the second current moment is greater than a third temperature threshold, the method further includes: if not, returning to the step of monitoring the real-time temperature of the coil of the shock absorber solenoid valve.

[0064] In some embodiments, after cooling the air spring, it also includes: determining whether the real-time temperature at the third current moment is less than a fourth temperature threshold, and if so, determining whether the second duration during which the real-time temperature is less than the fourth temperature threshold is greater than a second time threshold, and if so, 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 moment is less than the fourth temperature threshold, it indicates that the shock absorber temperature has dropped to a safety temperature, and the shock absorber temperature is low, and cooling the air spring can be stopped, i.e., stopping cooling the shock absorber. The second duration is the duration starting from the third current moment corresponding to when the real-time temperature is less than the fourth temperature threshold.

[0065] In some embodiments, after determining whether the real-time temperature at the third current moment is less than the fourth temperature threshold, it also includes: if not, continuing to cool the air spring, and returning to execute the step of determining whether the real-time temperature at the third current moment is less than the fourth temperature threshold.

[0066] In some embodiments, after cooling the air spring and the shock absorber solenoid valve, it also includes: judging whether the real-time temperature at the fourth current moment is less than the fourth temperature threshold, and if so, judging whether the third duration of the real-time temperature being less than the fourth temperature threshold is greater than the second time threshold, and if so, stopping cooling the air spring and the shock absorber solenoid valve, wherein the fourth current moment is any moment of cooling 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 moment is less than the fourth temperature threshold, it indicates that the shock absorber temperature has been reduced to a safe temperature, and cooling the air spring and the shock absorber solenoid valve can be stopped, that is, stopping cooling the shock absorber. The third duration is the duration starting from the fourth current moment corresponding to when the real-time temperature is less than the fourth temperature threshold.

[0067] In some embodiments, after determining whether the real-time temperature at the fourth current moment is less than the fourth temperature threshold, it also includes: if not, continuing to cool the air spring and the shock absorber solenoid valve, and returning to execute the step of determining whether the real-time temperature at the fourth current moment is less than the fourth temperature threshold.

[0068] In some embodiments, cooling the air spring and the shock absorber solenoid valve includes: discharging gas from the air spring and replenishing gas to the air spring, wherein the temperature of the replenished gas is lower than the temperature of the discharged gas; and controlling the operating current of the shock absorber solenoid valve to be the minimum operating current to minimize the heat generated by the shock absorber solenoid valve during operation.

[0069] In some embodiments, cooling the air spring comprises: exhausting gas from the air spring and replenishing gas to the air spring, wherein the temperature of the replenished gas is lower than the temperature of the exhaust gas. Exhausting high-temperature gas and replenishing low-temperature gas, that is, cooling the air spring by gas exchange.

[0070] In some embodiments, when the air spring is replenished with gas, gas at room temperature may be replenished.

[0071] In some embodiments, exhausting gas from the air spring and replenishing gas to the air spring includes: obtaining a first air flow rate, exhausting gas from the air spring according to the first air flow rate, and replenishing gas to the air spring according to the first air flow rate. The rate of exhausting gas is equal to the rate of replenishing gas, so that the amount of gas in the air spring remains unchanged.

[0072] In some embodiments, exhausting gas from the air spring and replenishing gas to the air spring includes: exhausting gas from the air spring at a maximum exhaust rate and replenishing gas to the air spring at a maximum gas replenishment rate. The air spring is greatly cooled by the maximum ventilation rate to improve the cooling efficiency.

[0073] In some embodiments, discharging gas from the air spring and replenishing gas to the air spring include: obtaining a target relationship characterizing the relationship between a temperature difference and an airflow rate, determining a first difference between the real-time temperature at the second current moment and the second temperature threshold, determining the second airflow rate based on the first difference and the target relationship, discharging gas from the air spring at the second airflow rate, and replenishing gas to the air spring at the second airflow rate.

[0074] In some implementations, for the target relationship, the greater the temperature difference, the greater the airflow rate.

[0075] In some embodiments, monitoring the real-time temperature of the shock absorber solenoid valve coil includes: obtaining the real-time current and real-time voltage of the shock absorber solenoid valve coil; determining the real-time resistance of the shock absorber solenoid valve coil based on the real-time current and the real-time voltage; and determining the real-time temperature based on the real-time resistance.

[0076] In some embodiments, determining the real-time temperature based on the real-time resistance includes: obtaining a preset relationship table representing the relationship between the resistance and temperature of the coil of the shock absorber solenoid valve; and determining the real-time temperature based on the real-time resistance and the preset relationship table. When the coil temperature changes, the resistance changes accordingly, so the temperature corresponding to the resistance can be obtained based on the preset relationship table. The preset relationship table can be obtained through a curve of resistance relative to temperature, or it can be obtained by calibration.

[0077] Exemplarily, the first temperature threshold is 80° C., the second temperature threshold is 120° C., the third temperature threshold is 100° C., the fourth temperature threshold is 60° C., the first time threshold is 1 s, and the second time threshold is 3 s.

[0082] In some embodiments, the second judgment unit is further configured to: determine whether the real-time temperature at the second current moment is greater than a second temperature threshold; if not, determine whether the real-time temperature at the second current moment is greater than a third temperature threshold; if so, cool the air spring, wherein the third temperature threshold is greater than the first temperature threshold and less than the second temperature threshold.

[0083] In some embodiments, a third judgment unit is also included, and the third judgment unit is used to judge whether the real-time temperature at the third current moment is less than a fourth temperature threshold after the air spring is cooled. If so, it is judged whether the second duration during which the real-time temperature is less than the fourth temperature threshold is greater than a second time threshold. If so, the cooling of the air spring is stopped, wherein the third current moment is any moment of cooling the air spring, and the fourth temperature threshold is less than the first temperature threshold.
