When the air compressor is running, it fills the air reservoir with compressed air. The air pressure sensor detects the air pressure inside the reservoir. When the air pressure inside the reservoir reaches a certain value, if the air compressor continues to fill the reservoir with compressed air, the excess compressed air in the reservoir is discharged through the pressure regulating valve.

[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] A vehicle is generally equipped with a braking system, which is composed of an air compressor, an air reservoir, a pipeline for transmitting compressed air between the air compressor and the air reservoir, an air pressure sensor, a pressure regulating valve and other components. In an example, the air compressor 1, the air reservoir 3, and the pipeline 3 for transmitting compressed air between the air compressor and the air reservoir in the braking system are as follows: Figure 1 As shown, when the air compressor is running, it produces compressed air 1, which is then filled into the air cylinder 3 through the pipeline 2 that transmits compressed air between the air compressor and the air cylinder. The air cylinder stores compressed air, and the air pressure sensor detects the air pressure in the air cylinder. When the air pressure in the air cylinder reaches a certain pressure value, if the air compressor continues to fill the air cylinder with compressed air, the excess compressed air in the air cylinder is discharged through the pressure regulating valve. In existing vehicles, the air compressor of the braking system is driven by the engine, and the speed of the air compressor is proportional to the speed of the engine, generating a large amount of excess compressed air during the driving of the vehicle. The air compressor in the braking system of existing vehicles generates a large amount of excess compressed air, which causes energy waste.

[0038] The embodiments of the present application provide a method, device, electronic device, and vehicle for controlling an air compressor. During vehicle operation, the pressure of an air reservoir is monitored. When the pressure reaches a first value, the compressed air in the reservoir meets the vehicle's braking requirements, and the air compressor's speed is controlled to decrease, thereby reducing the compressor's power and energy consumption. Furthermore, for electric vehicles, reducing the power consumed by the air compressor improves the vehicle's range.

[0039] Exemplary Implementation Environment

[0040] The method for controlling an air compressor provided in the embodiments of the present application is applicable to a braking system of an air compressor and an engineering vehicle that uses electricity as a power source, such as an electric excavator, an electric crane, an electric mixer truck, and other electric engineering vehicles.

[0041] The execution subject of the method provided in the embodiment of the present application is a controller, server or other equipment with data transmission and data processing functions. When applied to an electric engineering vehicle, the execution subject can be the controller of the braking system on the electric engineering vehicle.

[0042] Exemplary Methods

[0043] In some embodiments, a method for controlling an air compressor provided by an embodiment of the present application is as follows: Figure 1 As shown, the following steps may be included:

[0044] S210, monitoring the pressure value of the air tank.

[0045] The braking system of an electric engineering vehicle may include an air compressor, an air reservoir, connecting pipes, and an air pressure sensor. The air compressor and air reservoir are connected by connecting pipes to form the braking system's air circuit. The air pressure sensor monitors the pressure inside the air reservoir in real time. When the driver performs braking operations such as deceleration or parking, the braking system receives a braking signal from the vehicle's controller, causing the air reservoir to release air, thereby slowing or stopping the vehicle. This release of air from the air reservoir reduces the air pressure inside, causing the air compressor to inflate the air reservoir, increasing the pressure inside.

[0046] During the operation of the electric engineering vehicle, the air pressure sensor of the air reservoir detects the pressure value of the air reservoir in real time and sends the pressure value to the controller of the braking system. The controller receives the pressure value sent by the air pressure sensor.

[0047] S220: When the pressure value of the air storage cylinder reaches a first pressure value, the speed of the air compressor is controlled to decrease.

[0048] The first pressure value is a preset pressure value when the air reservoir meets the braking requirement of the vehicle.

[0049] When the pressure value of the air tank is lower than the first pressure value, the air compressor is controlled to run at the first speed to inflate the air tank. When the pressure value of the air tank rises to the first pressure value, the pressure value of the air tank meets the braking requirement of the vehicle. At this time, the speed of the air compressor is controlled to decrease.

[0050] Among them, when the pressure value of the air cylinder has not risen to the first pressure value, the air compressor is controlled to run at a set speed to quickly inflate the air cylinder. When the pressure value of the air cylinder rises to the first pressure value, the air compressor is controlled to stop running or reduce the speed.

[0051] S230: When the pressure value of the air storage cylinder drops to a second pressure value, the speed of the air compressor is controlled to increase.

[0052] The air compressor stops running and runs at a low speed. When the driver brakes or the brake system leaks, the pressure value of the air tank drops. When the pressure value of the air tank drops to a second pressure value, the speed of the air compressor is controlled to increase to improve the efficiency of charging the air tank.

[0053] The second pressure value is a preset pressure value when the air reservoir meets the braking requirements of the vehicle, and the first pressure value is greater than the second pressure value.

[0054] The second speed is greater than or equal to 0, that is, when the pressure value of the air storage cylinder drops to the second pressure value, the air compressor is controlled to start running or to increase the speed of operation.

[0055] The method provided in the embodiment of the present application monitors the pressure value of the air reservoir during vehicle operation. When the pressure value reaches a first pressure value, it indicates that the compressed air in the air reservoir has met the vehicle's braking needs. The speed of the air compressor is controlled to decrease, thereby reducing the power of the air compressor. When the pressure value of the air reservoir drops to a second pressure value after air operation or brake system leakage, the speed of the air compressor is controlled to increase. In other words, during the time when the compressed air in the air reservoir meets the vehicle's braking needs, the air compressor maintains a low speed or is shut down, reducing energy consumption. Moreover, for electric vehicles, reducing the electrical energy consumed by the air compressor improves the vehicle's endurance.

[0056] In one embodiment, the method may further include the following steps:

[0057] When the pressure value of the air storage cylinder is not monitored within the first preset time period, the air compressor is controlled to maintain the current speed.

[0058] When the pressure sensor of the air reservoir cannot detect the pressure value or the transmission line fails, causing the controller to be unable to receive the pressure value of the air reservoir, in order to ensure that the pressure in the air reservoir meets the braking requirements, the air compressor is controlled to maintain the current speed and continue to inflate the air reservoir.

[0059] In one embodiment, the first pressure value represents the minimum pressure required to meet braking requirements. From the moment the vehicle is started, the braking system is powered on and the pressure sensor monitors the pressure value of the air reservoir. If the pressure value is less than the first pressure value, the controller controls the air compressor to operate at a first speed. If the pressure value increases to a value greater than or equal to the first pressure value, the air compressor speed is controlled to decrease. If the controller does not receive the air reservoir pressure value within a first preset time period after the vehicle is started, it indicates that the air reservoir pressure sensor or transmission line has malfunctioned, and the air compressor is controlled to maintain the current speed.

[0060] In one example, the first preset duration is 2 minutes.

[0061] When the pressure value of the air cylinder cannot be monitored, the method provided in the embodiment of the present application controls the air compressor to maintain the current speed and continuously inflates the air compressor to ensure that the pressure in the air cylinder meets the braking requirements to ensure the driving safety of the vehicle.

[0062] In one embodiment, the method may further include the following steps:

[0063] When the pressure value of the air storage cylinder does not reach the first pressure value within the second preset time period, the speed of the air compressor is controlled to increase.

[0064] The preset time length is the time length for the pressure value of the air reservoir to reach the first pressure value under a preset normal state. Under a normal state, the pressure value of the air reservoir will rise to the first pressure value within the preset time length.

[0065] When the air compressor speed is lower than the set value or the brake system is leaking, the pressure in the air reservoir increases at a slower rate than normal. If the pressure in the air reservoir does not reach the first pressure value within the second preset time, it indicates a brake system failure. To meet the vehicle's braking needs, the air reservoir pressure must be quickly increased, the air compressor speed must be increased, and the inflation speed must be accelerated.

[0066] In one embodiment, the first pressure value represents the maximum pressure value that meets the braking requirement. When the driver brakes or the brake system leaks, the pressure value of the air reservoir drops below the first pressure value. At this time, the speed of the air compressor is controlled to increase. If the pressure value of the air reservoir does not reach the first pressure value within the second preset time for increasing the speed of the air compressor, it indicates that the brake system has failed. At this time, the speed of the air compressor is controlled to increase.

[0067] In one example, the second preset duration is 4 minutes.

[0068] The method provided in the embodiment of the present application controls the speed of the air compressor to increase and the inflation speed of the air compressor to ensure that the pressure in the air cylinder meets the braking requirements to ensure the driving safety of the vehicle when the pressure value of the air cylinder does not reach the first pressure value within the second preset time period.

[0069] In one embodiment, the method may further include the following steps:

[0070] When the pressure value of the air reservoir is not monitored within a first preset time period, or when the pressure value of the air reservoir does not reach a first pressure value within a second preset time period, a fault prompt signal is generated.

[0071] When the pressure value of the air tank is not monitored within the first preset time, or when the pressure value of the air tank does not reach the first pressure value within the second preset time, it indicates that there is a fault in the braking system, and the controller generates a fault prompt signal to prompt the driver to slow down or repair.

[0072] For example, a prompt signal is displayed through a human interface such as an instrument or a display screen, or a prompt signal is played through a speaker to remind the driver to drive slowly and inspect the vehicle as soon as possible.

[0073] The method provided in the embodiment of the present application generates a prompt signal to alert the driver when a fault occurs in the braking system, thereby ensuring safe driving of the vehicle.

[0074] In one embodiment, when the pressure value of the gas cylinder is not monitored within a first preset time period, generating a fault prompt signal may include the following steps:

[0075] When the pressure value of the air tank is not monitored within a first preset time period after the vehicle where the air compressor is located is started, a first fault prompt signal is generated.

[0076] The first fault prompt signal is used to prompt that there is a fault in the detection or transmission process of the pressure value of the air reservoir.

[0077] When the pressure value of the air cylinder is not monitored within the first preset time after the vehicle where the air compressor is located is started, it indicates that there is a fault such as the pressure sensor of the air cylinder cannot detect the pressure value or the transmission line that transmits the pressure value is faulty, and a first fault prompt signal is generated to prompt the driver that the pressure sensor or transmission line of the air cylinder has failed. Based on the first fault prompt signal, the driver knows that the pressure sensor and transmission line of the air cylinder need to be inspected.

[0078] The method provided in the embodiment of the present application generates a first fault prompt signal when the pressure value of the air cylinder is not monitored within a first preset time period after the vehicle where the air compressor is located is started, and specifically prompts the driver of the possible faulty device. The driver can carry out targeted maintenance and improve the user experience.

[0079] In one embodiment, when the pressure value of the air reservoir does not reach the first pressure value within the second preset time period, generating a prompt signal includes:

[0080] When the pressure value of the air reservoir does not reach the first pressure value within a second preset time period after the pressure value of the air reservoir is reduced to the second pressure value, a second fault prompt signal is generated.

[0081] The second fault prompt signal is used to prompt that a fault exists when the air compressor is producing compressed air, when the air compressor is transmitting compressed air to the air reservoir, and / or when the air reservoir is storing compressed air.

[0082] When the pressure value of the air tank does not reach the first pressure value within the second preset time period, it indicates that there is a fault such as the air compressor speed is lower than the set value, the air compressor is leaking, the air tank is leaking, or the transmission pipeline between the air compressor and the air tank is leaking, and a second fault prompt signal is generated to prompt the driver to inspect the air compressor for insufficient power, air compressor leakage, air tank leakage, or a fault in the transmission pipeline between the air compressor and the air tank. Based on the second fault prompt signal, the driver knows that it is necessary to inspect the air compressor line, air compressor, air tank and the transmission pipeline between the air compressor and the air tank for leaks.

[0083] The method provided in the embodiment of the present application generates a second fault prompt signal when the pressure value of the air cylinder does not reach the first pressure value within a second preset time period after the pressure value of the air cylinder is reduced to the second pressure value, so as to specifically prompt the driver of the possible faulty device. The driver can carry out targeted maintenance to improve the user experience.

[0084] In one embodiment, the fault prompt signal is used to control the lighting of a prompt light.

[0085] The controller generates a fault prompt signal, which controls the lighting of the prompt light at the corresponding position on the vehicle console to prompt the driver.

[0086] The present application is a method provided in an embodiment that generates a fault warning signal to control the lighting of a warning light, prompting the driver to slow down and carry out maintenance, thereby ensuring safe driving of the vehicle.

[0091] The first pressure value and the second pressure value are pressure values ​​when the air reservoir meets the braking requirements of the vehicle, and the first pressure value is greater than the second pressure value.

[0092] The device provided in the embodiment of the present application monitors the pressure value of the air reservoir during vehicle operation. When the pressure value reaches a first pressure value, it indicates that the compressed air in the air reservoir has met the vehicle's braking needs. The speed of the air compressor is controlled to decrease, thereby reducing the power of the air compressor. When the pressure value of the air reservoir drops to a second pressure value after air operation or brake system leakage, the speed of the air compressor is controlled to increase. In other words, during the time when the compressed air in the air reservoir meets the vehicle's braking needs, the air compressor maintains a low speed or stops, reducing energy consumption. Moreover, for electric vehicles, reducing the electrical energy consumed by the air compressor improves the vehicle's endurance.

[0103] The device provided in the embodiment of the present application generates a first fault warning signal when the pressure value of the air cylinder is not monitored within a first preset time after the vehicle where the air compressor is located is started, and specifically reminds the driver of the possible faulty device.

[0107] The device provided in the embodiment of the present application generates a second fault prompt signal when the pressure value of the air cylinder does not reach the first pressure value within a second preset time period after the pressure value of the air cylinder is reduced to the second pressure value, thereby specifically notifying the driver of a possible faulty component.
