Description

Technical Field

[0001] This invention relates to the field of vehicles, and more specifically, to a method, apparatus, and electronic device for preventing condensation in an air suspension system. Background Technology

[0002] As an important component of a vehicle, the air suspension system has the function of raising and lowering the vehicle, improving its handling stability and ride comfort. The high-pressure gas inside the air suspension system comes from the atmosphere. After being filtered by a filter, the gas is compressed by a compressor, and then the pressurized gas passes through a dryer to dry the water that condenses during compression.

[0003] However, due to the limited drying capacity of the desiccant in the drying canister, the humidity of the gas entering the air suspension system remains relatively high. As a result, if the air suspension system encounters temperature changes during subsequent operation, the humid air will condense into liquid water again, which can easily lead to water accumulation inside the air suspension system.

[0004] Therefore, prolonged water accumulation can easily cause malfunctions in the air suspension system, such as rust, abnormal noises, and component damage, which can lead to the air suspension system failing to function properly.

[0036] In the present embodiment, an anti-condensation control method of an air suspension system is provided, Figure 1 is a flow chart of an anti-condensation control method of an air suspension system according to an embodiment of the present application, as Figure 1 shown, the method comprises the following steps:

[0037] Step S12, obtaining target state information of the target vehicle and a first gas volume, wherein the target state information is used to determine whether the target vehicle is in a dormant state, and the first gas volume is used to represent the gas volume of each chamber in the air suspension system of the target vehicle.

[0038] In the above step S12, the target state information of the target vehicle and the first gas volume can be obtained.

[0039] Specifically, the target state information can be used to determine whether the target vehicle is in a dormant state, and the first gas volume is used to represent the gas volume of each chamber in the air suspension system of the target vehicle.

[0040] Figure 2 is a schematic diagram of an air suspension system according to an embodiment of the present application, as Figure 2 shown, the air suspension system mainly includes the following components: front air spring assembly 1, rear air spring assembly 2, gas distribution valve 3, air tank assembly 4, air supply unit assembly 5, and controller assembly 6. It should be noted that due to different structural designs, the gas distribution valve 3, the air supply unit assembly 5 and the controller assembly 6 can be integrated into an integrated structure.

[0041] Figure 3 is a schematic diagram of an anti-condensation control system of an air suspension system according to an embodiment of the present application, as Figure 3 shown, the anti-condensation control system of the air suspension system mainly includes the following components: air pressure sensor, second temperature sensor, first temperature sensor, air suspension system controller, gas distribution valve, air supply unit, left front air spring, right front air spring, left rear air spring, right rear air spring and air tank.

[0042] Specifically, the above-mentioned chamber can be Figure 3 the left front air spring, the right front air spring, the left rear air spring, the right rear air spring and the air tank in the air suspension system, so that there are five chambers in the above-mentioned air suspension system, including four air springs and one air tank, and the above-mentioned first gas volume can be used to represent the gas volume in each air spring or air tank.

[0043] In an optional embodiment, the air pressure sensor can be integrated inside the gas distribution valve or inside the air supply unit, and by combining the opening and closing of the electromagnetic valve, the air pressure sensor is only communicated with the measured chamber, so as to measure the air pressure inside each chamber, so as to calculate the gas volume of each chamber according to the air pressure inside each chamber.

[0044] It should be noted that the air pressure sensor is a necessary sensor in the air suspension system and does not need to be additionally increased. In order to ensure the accuracy of pressure measurement, pressure measurement can be performed for a preset duration, for example, the duration of pressure measurement can be set to 0.3s. At the same time, multiple measurements can be performed at a preset time interval, for example, the interval between two pressure measurements can be set to 0.2s.

[0045] Therefore, in step S12, it can be determined whether the target vehicle is in a dormant state, and the amount of gas inside each air spring and gas tank in the air suspension system can be obtained.

[0046] In step S14, target temperature data of the target vehicle is determined based on the target state information.

[0047] In the above step S14, the target temperature data of the target vehicle can be determined based on the target state information, wherein the target temperature data is the ambient temperature of the whole vehicle.

[0048] Specifically, when it is determined based on the target state information that the target vehicle is in an awakened state, the ambient temperature of the whole vehicle can be collected by using a whole vehicle temperature sensor, so as to obtain the target temperature data. When it is determined based on the target state information that the target vehicle is in a dormant state, temperature collection can be performed by using a temperature sensor welded on a controller circuit board, and the ambient temperature of the whole vehicle can be estimated in combination with a temperature evolution model, so as to obtain the target temperature data.

[0049] In step S16, in response to the target temperature data satisfying a first preset condition, gas exchange between each chamber in the air suspension system and the outside is controlled based on a first gas volume.

[0050] In the above step S16, when the target temperature data satisfies the first preset condition, gas exchange between each chamber in the air suspension system and the outside can be controlled based on the first gas volume.

[0051] In an optional embodiment, in response to a change value of the target temperature data within a preset time exceeding a preset threshold value, gas exchange between each chamber in the air suspension system and the outside is controlled based on the first gas volume, wherein the preset threshold value can be adjusted according to the volume and other characteristics of the air suspension system.

[0052] For example, when the ambient temperature of the whole vehicle decreases by more than 5℃ within 0.5h, 20% of the gas in each chamber can be extracted and an equal amount of air can be supplemented, so as to realize gas exchange between each chamber and the outside.

[0053] Based on the steps S12 to S16, by obtaining the target state information and the first gas volume of the target vehicle, and further determining the target temperature data of the target vehicle based on the target state information, and finally controlling the gas exchange between each chamber of the air suspension system and the outside based on the first gas volume in response to the target temperature data satisfying the first preset condition, the purpose of preventing air condensation and icing in the air suspension system is achieved, thereby realizing the technical effect of reducing the failure rate of the air suspension system, and further solving the technical problem of high failure rate of the air suspension system caused by air condensation in the air suspension system.

[0054] Optionally, in the step S14, the target temperature data of the target vehicle based on the target state information comprises:

[0055] In the step S141, in response to determining that the target vehicle is in the wake-up state based on the target state information, the first temperature data is obtained by using the first temperature sensor.

[0056] In the step S141, in response to determining that the target vehicle is in the wake-up state based on the target state information, the first temperature data is obtained by using the first temperature sensor, wherein the first temperature sensor is a vehicle temperature sensor, and the first temperature data is the ambient temperature of the vehicle collected by the vehicle temperature sensor.

[0057] It should be noted that the vehicle temperature sensor is a necessary sensor in the vehicle electrical system and does not need to be additionally added.

[0058] In the step S142, the first temperature data is determined as the target temperature data.

[0059] In the step S142, the first temperature data obtained by the first temperature sensor is determined as the target temperature data.

[0060] Specifically, when it is determined that the target vehicle is in the wake-up state based on the target state information, the ambient temperature of the vehicle can be collected by the vehicle temperature sensor to obtain the target temperature data.

[0061] Based on the steps S141 to S142, by obtaining the first temperature data by using the first temperature sensor in response to determining that the target vehicle is in the wake-up state based on the target state information, and further determining the first temperature data as the target temperature data.

[0062] Optionally, in the step S14, the target temperature data of the target vehicle based on the target state information comprises:

[0063] In the step S143, in response to determining that the target vehicle is in the sleep state based on the target state information, the second temperature data is obtained by using the second temperature sensor.

[0064] In the step S143, the second temperature sensor is a temperature sensor welded on the controller circuit board, and the second temperature data is temperature data collected by the temperature sensor welded on the controller circuit board when the vehicle is in the sleep state.

[0065] Specifically, when it is determined based on the target state information that the target vehicle is in the sleep state, the temperature data of the whole vehicle collected by the whole vehicle temperature sensor cannot be obtained, and therefore the ambient temperature of the whole vehicle can be estimated based on the temperature data collected by the temperature sensor welded on the controller circuit board.

[0066] In the step S144, the target temperature data is determined based on the second temperature data and the temperature evolution model.

[0067] In the step S144, after the second temperature data is obtained by the second temperature sensor in response to the determination based on the target state information that the target vehicle is in the sleep state, the target temperature data is determined based on the second temperature data and the temperature evolution model.

[0068] Specifically, when the vehicle is in the sleep state, the ambient temperature of the whole vehicle can be estimated based on the temperature data collected by the temperature sensor welded on the controller circuit board and the temperature evolution model.

[0069] Based on the steps S143 to S144, by obtaining the second temperature data by the second temperature sensor in response to the determination based on the target state information that the target vehicle is in the sleep state, and then determining the target temperature data based on the second temperature data and the temperature evolution model, the target temperature data can be determined when the target vehicle is in the sleep state without waking up the vehicle, so that the system power consumption can be saved, and in addition, the temperature sensor welded on the controller circuit board is easy to obtain and has low cost, so that the cost can be saved.

[0070] Optionally, in the step S144, the determination of the target temperature data based on the second temperature data and the temperature evolution model comprises:

[0071] In the step S1441, the third temperature data is determined by the temperature evolution model, and the third temperature data is used to represent the temperature change caused by the air suspension system.

[0072] In the step S1441, the temperature evolution model can determine the temperature change caused by the air suspension system.

[0073] Figure 4 FIG. 1 is a schematic diagram of determining target temperature data according to an embodiment of the present application, and the temperature evolution model can determine the temperature change caused by the air suspension system by calculating heat accumulation and heat dissipation.

[0074] Specifically, since the temperature sensor and the power device soldered on the controller circuit board have a certain distance, the distance will affect the heat accumulation of the temperature sensor soldered on the controller circuit board caused by the heat of the power device; in addition, the different temperatures of the power device will also cause the change of the heat accumulation coefficient.

[0075] The above heat accumulation coefficient can be an array, that is, different power devices correspond to a heat accumulation coefficient. The current working power devices of the system can obtain the heat accumulation speed of the power characteristic, and then multiply the heat accumulation speed by the corresponding heat accumulation coefficient, and then integrate the multiplied result to obtain the heat accumulation.

[0076] Since the power devices that are turned on by the air suspension system in different operating modes and different operating times can be different, the operating mode and operating time of the air suspension system will also affect the heat accumulation.

[0077] In addition, the resistance heating of the power device will cause heat accumulation, and at the same time, the resistance heating of the power device will also affect the resistance of the power device.

[0078] Like the heat accumulation coefficient, the design of the heat dissipation structure of the controller circuit board and the internal and external temperature difference of the controller jointly determine the heat dissipation coefficient. The controller will always exchange heat with the air suspension system, and the heat dissipation speed is different in different working modes of the air suspension system. Multiply the heat dissipation speed corresponding to the working mode of the air suspension system by the heat dissipation coefficient, and then integrate the multiplied result to obtain the heat dissipation.

[0079] After obtaining the heat accumulation and heat dissipation, the heat accumulation and heat dissipation need to be limited. Since the heat accumulation and heat dissipation are the changes of temperature in each operation period, and the change speed of the change amount has a physical limit, the heat accumulation slope limit and the heat dissipation slope limit can avoid the accumulated value change too much.

[0080] Therefore, it can be known that the temperature evolution model can simulate the temperature change caused by the air suspension system at each moment.

[0081] In step S1442, the fourth temperature data is determined based on the second temperature data and the third temperature data, and the fourth temperature data is used to represent the change of the environment temperature.

[0082] In the above step S1442, the fourth temperature data can be determined based on the second temperature data and the third temperature data.

[0083] Specifically, the fourth temperature data is used to represent the ambient temperature change, and the temperature change caused by the air suspension system is removed from the temperature data collected by the temperature sensor welded on the controller circuit board when the second temperature data and the third temperature data determine the fourth temperature data, so that the pure ambient temperature change can be obtained.

[0084] In step S1443, the target temperature data is determined based on the initial temperature data and the fourth temperature data.

[0085] In the above step S1443, the initial temperature data is the ambient temperature obtained by the first temperature sensor at a time point before the target vehicle enters the sleep state.

[0086] Specifically, when the vehicle just enters the sleep state, the ambient temperature of the vehicle obtained by the first temperature sensor at a time point before the vehicle enters the sleep state can be used as the initial temperature, and the ambient temperature of the vehicle at any subsequent time point can be estimated in combination with the above ambient temperature change, so as to obtain the target temperature data.

[0087] Based on the above steps S1441 to S1443, the third temperature data is determined by using the temperature evolution model, and then the fourth temperature data is determined based on the second temperature data and the third temperature data, and finally the target temperature data is determined based on the initial temperature data and the fourth temperature data. Ambient temperature of the vehicle can be estimated when the target vehicle is in sleep mode, without waking up the vehicle, so as to save the power consumption of the system.

[0088] Optionally, in the above step S16, the gas exchange between each chamber of the air suspension system and the outside based on the first gas capacity includes:

[0089] In step S161, the first target gas capacity is determined based on the first gas capacity and the first preset threshold, wherein the first target gas capacity is the amount of gas to be exchanged in each chamber.

[0090] In the above step S161, the first preset threshold can be a percentage of the first gas capacity, for example, 20% of the gas in the gas tank is exchanged with the outside.

[0091] In step S162, the gas exchange between each chamber of the air suspension system and the outside is controlled based on the first target gas capacity.

[0092] For example, 20% of the gas in each chamber is extracted, and an equal amount of air is obtained from the atmosphere to supplement each chamber.

[0093] Based on the steps S161 to S162, by determining the first target gas volume based on the first gas volume and the first preset threshold, and then controlling the gas exchange of each chamber of the air suspension system with the outside based on the first target gas volume, the condensation of air in the air suspension system can be prevented, thereby avoiding the malfunction of the air suspension system caused by air condensation.

[0094] In an optional embodiment, after the whole vehicle is in sleep, the controller of the air suspension system can also be timed to wake up, and the temperature data of the whole vehicle can be collected, and then it can be judged whether the difference between the collected temperature data of the whole vehicle and the estimated temperature data of the whole vehicle at sleep exceeds a preset threshold, and if it exceeds the preset threshold, each chamber is controlled to exchange gas based on the first target gas volume.

[0095] Optionally, in the step S17, the anti-condensation control method of the air suspension system further comprises:

[0096] Step S171, in response to the target temperature data satisfying a second preset condition, starting a target strategy, wherein the target strategy is used to prevent the air suspension system from icing.

[0097] In the above step S171, the target strategy is an anti-icing strategy, and when the ambient temperature of the whole vehicle is less than a preset threshold, for example, the ambient temperature of the whole vehicle is reduced to below 0℃, the anti-icing strategy of the air suspension system is started.

[0098] Because when the ambient temperature of the whole vehicle is reduced to below 0℃, if there is liquid water in the air suspension system, icing will occur, and the air suspension system may have problems such as pipeline blockage and valve freezing, thereby affecting the work of the air suspension system, therefore, in this case, the anti-icing strategy needs to be started.

[0099] Step S172, in response to the target strategy being in the starting state, determining a second target gas volume based on the first gas volume and a second preset threshold, wherein the second target gas volume is the gas volume to be exchanged by each chamber of the air suspension system corresponding to the target strategy.

[0100] In the above step S172, after starting the anti-icing strategy, the gas volume that each chamber needs to exchange with the outside can be determined, for example, 10% of the gas volume of each chamber.

[0101] Step S173, controlling the gas exchange of each chamber of the air suspension system with the outside based on the second target gas volume.

[0102] For example, each chamber can be controlled to discharge 10% of the gas into the atmosphere, so as to blow out the liquid water possibly existing in the pipeline, valve and other parts, and then an equal amount of gas is supplemented into each chamber from the atmosphere, so that the air suspension system failure caused by the freezing of liquid water can be avoided.

[0103] Based on the steps S171 to S173, by responding to the target temperature data satisfying the second preset condition, the target strategy is started, and then by responding to the target strategy being in the started state, the second target gas volume is determined based on the first gas volume and the second preset threshold, and finally the gas exchange between each chamber of the air suspension system and the outside is controlled based on the second target gas volume, so that the air suspension system failure caused by the freezing of liquid water can be avoided.

[0104] Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be realized by means of software and the necessary general hardware platform, and of course it can also be realized by hardware, but in many cases the former is a better embodiment. Based on such understanding, the technical solutions of the present application or the part that contributes to the prior art can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes a plurality of instructions for making a terminal device (which can be a mobile phone, computer, server, or network device, etc.) execute the method described in each embodiment of the present application.
