Existing electronic parking systems use push-button control to open and close the electronic brake parking valve to achieve braking and release functions. During vehicle operation, issues such as hardware aging, valve failure, and weather conditions can cause air circuit leaks. Because air brake vehicles use a disconnected air brake design, any air circuit leak will directly affect the proper functioning of the braking system, seriously threatening driving safety and potentially endangering the driver and public safety. Therefore, ensuring the integrity of the air circuit system and regular maintenance are crucial. Summary of the Invention

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0025] Example 1

[0026] Figure 1 This is a flow chart of the parking system control method in the embodiment, refer to Figure 1 , parking system air replenishment methods include:

[0027] S101. Detect the parking chamber pressure. If the parking chamber pressure is less than a first pressure threshold, control the parking chamber to be filled with air.

[0028] In this solution, the parking system is an air brake electronic parking system for commercial vehicles (such as trucks, buses, etc.). The air brake electronic parking system relies on compressed air to achieve the parking brake function.

[0029] In this solution, the parking chamber is a chamber in the parking system that stores compressed air. The compressed air forms pressure in the parking chamber, pushing the braking mechanism to park the vehicle.

[0030] In this solution, the parking chamber pressure is the pressure generated by the compressed air in the parking chamber, which directly affects the effectiveness of the parking brake. If the pressure is insufficient, the parking brake may fail, causing safety hazards such as vehicle rolling.

[0031] In this solution, the parking chamber is controlled to be filled with air by starting an air filling device (such as an air pump, a solenoid valve, etc.) through the vehicle electronic control system to fill the parking chamber with compressed air to increase the parking chamber pressure to an appropriate range.

[0032] S102. If the parking chamber pressure is still lower than the first pressure threshold after air replenishment, a fault prompt is generated. Before the fault is eliminated, if the vehicle is in a driving condition, the parking chamber continues to be replenished with air.

[0033] In this solution, the gas replenishment may be after a set time has passed since the gas replenishment was started, or the gas replenishment has been performed a specified number of times.

[0034] In this solution, the fault prompt is used when the parking chamber pressure still does not reach the first pressure threshold after air replenishment. The vehicle will feedback to the driver that there is a fault in the parking system through the instrument panel indicator light, buzzer alarm, display text prompt, etc., to remind the driver to deal with it in time.

[0035] In this solution, before fault elimination is the period from when the system detects the fault and generates a fault prompt to when the driver or maintenance personnel repairs the fault and restores the parking system to normal working state.

[0036] In this solution, the parking chamber is continuously replenished with air. Before the fault is eliminated, as long as the vehicle is in the driving condition, if the pressure in the parking chamber is too low, the air replenishing device will continuously fill the parking chamber with compressed air to maintain the parking chamber pressure and try to ensure the effectiveness of the parking brake function.

[0037] For example, in this solution, a pressure sensor can be installed in the parking cavity to monitor the parking cavity pressure in real time and transmit the pressure data to the vehicle electronic control unit (ECU). The ECU pre-sets a first pressure threshold.

[0038] When the ECU determines that the parking chamber pressure is lower than the first pressure threshold, it immediately sends a command to activate the air supply device. The air pump in the air supply device starts working, controlling the gas flow through the solenoid valve to fill the parking chamber with compressed air.

[0039] After the air is replenished, the ECU reads the parking chamber pressure data again. If the pressure is still below the first pressure threshold, it indicates that there may be a system failure, such as an air line leak or air pump failure. At this time, the ECU controls the parking fault indicator on the vehicle's instrument panel to illuminate, indicating that the parking system is faulty.

[0040] While the fault is still present, the vehicle speed sensor monitors the vehicle's driving status in real time. Once the vehicle is detected to be in driving condition, the ECU continuously sends commands to the air supply device to continuously supply air to the parking chamber until the fault is resolved.

[0041] This embodiment proposes a parking system air replenishment method. This method ensures that the parking chamber pressure is maintained at a safe level through real-time monitoring and timely air replenishment, effectively preventing vehicle rollaway accidents caused by insufficient parking chamber pressure and ensuring vehicle safety while parked. After a fault occurs, continued air replenishment during driving conditions further reduces safety risks associated with the fault. This air replenishment method maintains basic functionality until the fault is resolved, improving the reliability and stability of the entire parking system.

[0042] Based on any of the above solutions, in one possible implementation, when controlling the air replenishment of the parking chamber, if the parking chamber pressure is greater than a first pressure threshold within a set time, it is determined that air replenishment is not required.

[0043] In this solution, during the process of replenishing air in the parking chamber, a specific time period is set, and the parking chamber pressure is continuously monitored during this time period.

[0044] If the parking chamber pressure rises and exceeds the preset first pressure threshold within the set time, it means that the current air replenishment operation has achieved the expected effect and the parking chamber pressure is sufficient to meet the parking brake requirements. At this time, the system determines that there is no need to continue replenishing air and stops the air replenishment action in time.

[0045] In this solution, excessive air replenishment can be avoided, energy can be saved, and unnecessary working losses of the air replenishment device can be reduced, thereby extending its service life. It can also prevent excessive air replenishment from causing excessive parking chamber pressure, causing brake system failure or affecting the braking effect, thereby ensuring stable and reliable operation of the parking system.

[0046] For example, in this solution, a gas replenishment time threshold and a first pressure threshold can be pre-set in the vehicle's electronic control unit (ECU). When the ECU detects that the parking chamber pressure is less than the first pressure threshold, the gas replenishment device is immediately activated, the air pump begins operating, the solenoid valve controls the gas flow, and compressed air is injected into the parking chamber. Simultaneously, an internal timer is started.

[0047] During the air replenishment process, a pressure sensor installed in the parking chamber collects real-time pressure data at a fixed frequency (e.g., 10 times per second) and transmits it to the ECU. Each time the ECU receives pressure data, it compares it with a first pressure threshold and checks whether the time recorded by the timer has reached the set air replenishment time threshold.

[0048] If, within the set time, the ECU determines that the parking chamber pressure is greater than the first pressure threshold, it immediately sends a command to stop the air supply device, stopping the air pump and closing the air circuit with the solenoid valve, thus completing the air supply operation. If, after the set time expires, the parking chamber pressure remains less than or equal to the first pressure threshold, the subsequent process continues according to the original plan, such as generating a fault prompt.

[0049] Based on any of the above solutions, in one possible implementation scheme, when controlling the air replenishment of the parking chamber, if it is detected that the parking chamber pressure continues to drop within a set time, a fault prompt is generated.

[0050] In this solution, the pressure trend is monitored during the parking chamber air replenishment process. If the pressure continues to drop within the set time, it indicates that the air replenishment operation has not achieved the expected effect, and there is a high probability of a serious air leakage or failure of the air replenishment device.

[0051] Once the system identifies the above abnormal situation, it will immediately generate a fault prompt to inform the driver in time that there is a problem with the parking system so that the driver can take appropriate measures to avoid serious consequences such as parking brake failure due to untimely fault handling, thereby ensuring the safety of vehicle operation.

[0052] For example, in this solution, a monitoring time threshold (e.g., 20 seconds) is pre-set in the vehicle electronic control unit (ECU). When the ECU determines that the parking chamber needs to be replenished with air, the air replenishment device is activated and the pressure monitoring program is started at the same time.

[0053] The air pump in the air supply device runs, the solenoid valve controls the gas flow direction, and compressed air is filled into the parking cavity. The pressure sensor installed in the parking cavity collects pressure data in real time at a high frequency (such as 5 times per second) and transmits the data to the ECU.

[0054] The ECU analyzes the received pressure data. Within the set monitoring time, each new set of pressure data is compared with the previous set to determine whether the pressure is rising, falling, or remaining constant. If pressure drops are detected multiple times within the set time range, the pressure is considered to be continuously falling.

[0055] When the ECU determines that the parking chamber pressure continues to drop within the set time, the fault prompt program is immediately triggered.

[0056] This solution monitors pressure trends during the air replenishment process, enabling early detection of anomalies. Compared to simply determining whether the pressure meets the required level after air replenishment, this solution can pinpoint the problem more quickly and accurately, especially for problems like air leaks that cause a continuous drop in pressure. This significantly shortens diagnostic time and improves troubleshooting efficiency.

[0057] Based on any of the above solutions, in one possible implementation scheme, when controlling the air replenishment of the parking chamber, if the number of times the air replenishment is started reaches a set number within a set time, a fault prompt is generated.

[0058] In this solution, the system records the number of air replenishment activations within a set timeframe in real time while the parking chamber is being refilled. If the number of air replenishment activations reaches a pre-set number within the set timeframe, this indicates that the air replenishment operation has failed to effectively raise the parking chamber pressure to the target value. This indicates a potential malfunction, such as an air line leak, degraded air replenishment device performance, or a pressure sensor anomaly.

[0059] At this time, the system generates a fault prompt to promptly remind the driver that there is a problem with the parking system so that it can be repaired as soon as possible to avoid failure of the parking brake due to the fault and ensure the safe operation of the vehicle.

[0060] For example, in this solution, a monitoring time threshold and a gas injection threshold are pre-set in the vehicle's electronic control unit (ECU). Furthermore, a counter is set within the ECU to record the number of gas injection activations, with an initial value of 0. The counter begins operating when the ECU determines that the parking chamber pressure is less than a first pressure threshold and initiates the gas injection operation.

[0061] Each time the ECU initiates the air replenishment (the air pump runs, the solenoid valve opens, and the parking chamber is filled with air), a counter automatically increments by 1. During the set monitoring time, the pressure sensor continuously transmits parking chamber pressure data to the ECU, which determines whether the pressure has reached the first pressure threshold after air replenishment. If it has not reached the first pressure threshold and air replenishment is initiated again, the counter continues to increment.

[0062] At the end of the set time, the ECU checks the number of gas injections recorded by the counter. If the number of gas injections reaches or exceeds the set threshold, the ECU immediately triggers the fault prompt program.

[0063] Based on any of the above solutions, in one possible implementation scheme, before detecting the parking chamber pressure, the method further includes:

[0064] The air pressure of the parking chamber is detected. If the air pressure is less than the second pressure threshold, it is determined that the vehicle has an air leak. If the vehicle has an air leak, the parking chamber pressure is further detected to see if it is less than the first pressure threshold.

[0065] This solution first checks the parking chamber's air pressure before testing the parking chamber's pressure, establishing a dual pressure detection mechanism. Air pressure is essential for the proper functioning of the parking system. If the air pressure falls below a pre-set second pressure threshold, it indicates a gas leak, potentially putting the vehicle's parking brake at risk of failure.

[0066] Based on this, further testing to see if the parking chamber pressure is below the first pressure threshold can more accurately determine the severity and scope of the fault. If the parking chamber pressure is also below the standard, it indicates that the fault has a significant impact on the parking function and requires immediate action. If the parking chamber pressure is normal, the leak can be preliminarily determined to be in the air path outside the parking chamber, narrowing the scope for subsequent repairs, thereby improving the accuracy of fault diagnosis and repair efficiency.

[0067] For example, in this solution, the second and first pressure thresholds are pre-set in the vehicle's electronic control unit (ECU). During parking system operation, air pressure sensors installed at key points in the air path (such as the air tank outlet and air path branches) collect air path pressure data in real time and transmit the data to the ECU.

[0068] The ECU analyzes the received air path pressure data and determines that the vehicle has an air leak when it detects that the air path pressure is less than a second pressure threshold.

[0069] After determining that the vehicle has an air leak, the ECU initiates a parking chamber pressure test. The pressure sensor installed in the parking chamber begins operating, transmitting real-time parking chamber pressure data to the ECU. The ECU then compares the parking chamber pressure with a first pressure threshold.

[0070] If the parking chamber pressure is greater than or equal to the first pressure threshold, it indicates that the current air leakage has little effect on the parking chamber pressure. If the parking chamber pressure is less than the first pressure threshold, it indicates that the air leakage problem has affected the parking function and the ECU generates a fault prompt.

[0071] In this solution, the dual pressure detection mechanism enables the system to distinguish different air leak situations, determining both the presence of a leak and its impact on the parking chamber pressure. This avoids misjudgments or missed detections caused by a single test, making fault diagnosis more accurate. Maintenance personnel can quickly locate the fault point based on the prompts, reducing troubleshooting time and improving repair efficiency.

[0072] Based on any of the above solutions, in one possible implementation scheme, the fault prompt is used to flash on the control instrument and the electronic parking brake button.

[0073] In this solution, the presentation of fault prompts focuses on the vehicle's instrument panel and electronic parking brake button, and by controlling the two to flash, the warning effect is enhanced with visual signals.

[0074] When a parking system malfunctions, the instrument and buttons will flash, which can immediately attract the driver's attention in a highly recognizable and intuitive manner, ensuring that the driver will not ignore the fault information, thereby promptly understanding the abnormal situation of the parking system and providing effective reminders for subsequent response measures to ensure driving safety.

[0075] For example, in this solution, when the vehicle electronic control unit (ECU) detects a fault in the parking system (such as the pressure still does not meet the standard after air replenishment, the pressure continues to drop during the air replenishment process, etc.), the ECU immediately generates a fault signal and sends the signal to the instrument control module and the electronic parking brake button control module.

[0076] After receiving the fault signal, the instrument control module starts the flashing program. By adjusting the flashing frequency of the fault indicator light or related display area on the instrument display (for example, flashing once per second) and combining it with color changes (such as changing from regular green to flashing red), the fault information is intuitively conveyed to the driver.

[0077] At the same time, the fault code or brief fault description, such as abnormal parking pressure, is displayed synchronously on the instrument display screen, making it easier for the driver to further understand the fault details.

[0078] After receiving the fault signal, the electronic parking brake button control module also starts the flashing program. The indicator light on the control button flashes regularly and the backlight color of the button changes (for example, from white to flashing yellow) to enhance the visual warning effect.

[0079] Before the fault is eliminated, the instrument panel and the electronic parking brake button will continue to flash. When the ECU detects that the fault has been eliminated, it sends a fault elimination signal to the instrument panel control module and the electronic parking brake button control module. After receiving the signal, the two modules stop flashing and return to normal display status.

[0080] Figure 2 This is another flow chart of the parking system control method in the embodiment, refer to Figure 2 Based on any of the foregoing solutions, in one possible implementation method, the method includes:

[0081] S201. Detect the air pressure of the parking chamber. If the air pressure is less than a second pressure threshold, determine that the vehicle has an air leak.

[0082] S202. If the vehicle has an air leak, the parking chamber pressure is detected. If the parking chamber pressure is less than a first pressure threshold, air is replenished in the parking chamber.

[0083] S203. If the parking chamber pressure is still lower than the first pressure threshold after air replenishment, a fault prompt is generated. Before the fault is eliminated, if the vehicle is in a driving condition, the parking chamber is continuously replenished with air.

[0084] In this solution, when controlling the air replenishment of the parking chamber, if the pressure of the parking chamber is greater than the first pressure threshold within a set time, it is determined that air replenishment is not required.

[0085] When the parking chamber is replenished with air, if a continuous decrease in the parking chamber pressure is detected within the set time, a fault prompt is generated.

[0086] When controlling the air replenishment of the parking chamber, if the number of air replenishment starts reaches the set number within the set time, a fault prompt is generated.

[0087] In this solution, the fault prompt is used to flash on the control instrument and electronic parking brake button.

[0088] Example 2

[0089] This embodiment provides a parking system air supply device, including a parking system air supply unit, which is used to:

[0090] The parking chamber pressure is detected. If the parking chamber pressure is less than a first pressure threshold, the parking chamber is controlled to be replenished with air. If the parking chamber pressure is still less than the first pressure threshold after replenishing the air, a fault prompt is generated. Before the fault is eliminated, if the vehicle is in a driving condition, the parking chamber is continuously replenished with air.
