Description

Technical Field

[0001] The invention relates to the technical field of parking air conditioners, and in particular provides a control method for an anti-fatigue driving type parking air conditioner. Background Art

[0002] Parking air conditioners are often installed on vehicles to adjust the temperature of the cockpit. However, for different application scenarios, parking air conditioners that only adjust the temperature no longer meet actual needs. Heavy truck drivers will inevitably enter a state of fatigue driving during long-distance transportation, and fatigue driving will bring major safety hazards to drivers. If the functions of parking air conditioners can be extended to avoid driver fatigue driving, it will undoubtedly greatly improve the user experience.

[0003] Accordingly, the art requires a new parking air conditioner control method to solve the above problems. Summary of the invention

[0004] The present invention aims to solve the above technical problem, that is, to solve the problem that the existing parking air conditioner cannot remind the driver of fatigue driving. To this end, the present invention provides a control method of an anti-fatigue driving parking air conditioner, the control method comprising the following steps:

[0005] Start the parking air conditioner;

[0006] Get the driver's action information;

[0007] According to the action information, the anti-fatigue driving preset program is selectively executed.

[0008] In the specific implementation of the above-mentioned anti-fatigue driving type parking air conditioner control method, the step of "selectively executing the anti-fatigue driving preset program according to the action information" includes the following:

[0009] When the motion information is a light fatigue motion, dynamic music is played.

[0010] In the specific implementation of the above anti-fatigue driving type parking air conditioner control method, the step of "selectively executing the anti-fatigue driving preset program according to the action information" includes the following:

[0011] When the action information is a moderately fatigued action, the voice assistant is turned on.

[0012] In the specific implementation of the above-mentioned anti-fatigue driving type parking air conditioner control method, the step of "selectively executing the anti-fatigue driving preset program according to the action information" includes the following:

[0013] When the action information is a severe fatigue action, a reserved phone number is dialed.

[0014] In a specific implementation of the control method of the above-mentioned anti-fatigue driving parking air conditioner, mild fatigue actions include yawning and / or stretching, moderate fatigue actions include no major movements of the hands within the first set time, and severe fatigue actions include leaning forward, backward, or left or right of the head.

[0015] In a specific implementation of the above-mentioned anti-fatigue driving type parking air conditioner control method, the control method further includes the following steps:

[0016] When the parking air conditioner is started, determine whether the vehicle is in a driving state;

[0017] If yes, start timing, otherwise continue to determine whether the vehicle is in a driving state;

[0018] Determine whether the timing time exceeds the second set time;

[0019] If yes, the aromatherapy system is turned on intermittently, otherwise it is determined whether the timing time exceeds the third set time;

[0020] If yes, the fresh air system is turned on intermittently, otherwise it is determined whether the timing time exceeds the fourth set time;

[0021] If yes, lower the indoor temperature, otherwise continue timing.

[0022] In the specific implementation of the control method of the anti-fatigue driving type parking air conditioner, the step of "if yes, then lowering the indoor temperature" includes the following:

[0023] Based on the existing indoor temperature, the first set temperature is lowered.

[0024] In the specific implementation of the control method of the anti-fatigue driving type parking air conditioner, the step of "if yes, then intermittently turning on the fresh air system" includes the following:

[0025] After the first preset time, the fresh air is turned on once, and the opening time is the second preset time.

[0026] In the specific implementation of the control method of the anti-fatigue driving type parking air conditioner, the step of "if yes, then intermittently turning on the aromatherapy system" includes the following:

[0027] After the third preset time, the aromatherapy system is turned on once, and the duration is the fourth preset time.

[0028] A control method for an anti-fatigue driving parking air conditioner, the control method comprising the following steps:

[0029] Start the parking air conditioner;

[0030] Detect and determine whether each module is operating normally;

[0031] If yes, then obtain the driver's action information, otherwise standby and alarm;

[0032] When the action information is a light fatigue action, dynamic music is played;

[0033] When the action information is a moderate fatigue action, the voice assistant is turned on;

[0034] When the action information is a severe fatigue action, dial a reserved phone number;

[0035] When each module operates normally, it determines whether the vehicle is in driving state;

[0036] If yes, start timing, otherwise continue to determine whether the vehicle is in a driving state;

[0037] Determine whether the timing time exceeds the second set time;

[0038] If yes, the aromatherapy system is turned on intermittently, otherwise it is determined whether the timing time exceeds the third set time;

[0039] If yes, the fresh air system is turned on intermittently, otherwise it is determined whether the timing time exceeds the fourth set time;

[0040] If yes, lower the indoor temperature, otherwise continue timing.

[0041] The beneficial effect of the control method of the anti-fatigue driving parking air conditioner provided by the present invention is that the parking air conditioner can judge the driver's fatigue level according to the driver's action information, and then choose to execute a highly targeted anti-fatigue driving preset program, which can effectively improve the driver's attention and remind the driver to take a rest in time, which can not only effectively complete the transportation task, but also reduce the risk of the driver in a fatigue driving state.

[0042] Furthermore, for different degrees of driving fatigue, different degrees of reminder methods are adopted to avoid excessive impact on the driver and insufficient impact on the driver. This flexible reminder method combines the real needs of the driver and avoids excessive worry of relevant personnel.

[0043] Furthermore, in order to more effectively reduce the driver's fatigue level and increase the driver's vigilance through the dimension of time, three modes are gradually adopted according to the driver's driving time: lowering the indoor temperature, intermittently turning on the fresh air system, and intermittently turning on the aromatherapy system, which greatly improves the driver's vigilance.

[0044] Furthermore, the two anti-fatigue driving methods complement each other and do not interfere with each other. Not only does it solve the problem of a single anti-fatigue driving method delaying the driver's transportation task or increasing the driver's danger when it fails, it also improves the stability and reliability of the system's anti-fatigue driving function, thereby improving the user experience.

[0052] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the relevant devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, ordinal numbers such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0053] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] It should be noted that the parking air conditioner of the present invention is installed on the top of the heavy truck cab, and the hot and cold air is sent into the cab through the top air outlet. Figure 5 As shown, a control panel 2, a camera 3, a voice module 4 and a communication module 5 are installed in the center of the air outlet of the parking air conditioner 1. Among them, a controller is set in the parking air conditioner, and the control panel 2, the camera 3, the voice module 4 and the communication module 5 are all electrically connected to the controller.

[0055] like Figure 1 As shown, the present invention proposes a control method for an anti-fatigue driving type parking air conditioner, and the control method comprises the following steps:

[0056] Step S1: starting the parking air conditioner;

[0057] Step S2: obtaining the driver's action information;

[0058] Step S3: selectively executing the anti-fatigue driving preset program according to the action information.

[0059] In this embodiment, when the parking air conditioner is started, the corresponding camera, voice module and communication module will also be started. The camera is used to capture the driver's motion information. According to the acquired motion information, the driver's state is judged accordingly, and then a more targeted program is executed accordingly, which is conducive to improving the driver's sense of security and reducing the driver's anxiety.

[0060] Compared with a single anti-fatigue driving reminder method, the present invention can effectively improve driving safety and greatly reduce the driver's own anxiety. For example, when the driver is in a state of mild fatigue, dynamic music can be played. The playing of dynamic music can let the driver know his fatigue state and improve his mood, so that the driver can judge whether he needs to stop and rest.

[0061] Alternatively, when the driver is in a state of moderate fatigue, the voice assistant can be turned on to allow the driver to interact with the voice assistant. The interactive form can improve the driver's attention and prevent the driver from becoming physically relaxed due to lack of concentration and entering a state of fatigue more quickly.

[0062] Or, when the driver is in a state of severe fatigue, such drivers often bear a lot of life pressure, so they drive for a long time. In order to make the driver realize the dangers of fatigue driving as soon as possible, the reserved phone number can be called to let the driver's relatives understand and comfort the driver from a psychological perspective, so that the driver can correctly realize his dangerous behavior. This method of calling the reserved phone number, when the driver is not in a state of severe fatigue driving, once executed, will not only increase the driver's psychological burden, but also easily cause the driver to make misjudgments due to anxiety.

[0063] Further, if Figure 2 As shown, the step of "selectively executing the anti-fatigue driving preset program according to the action information" includes the following: Step S31: when the action information is a mild fatigue action, playing dynamic music.

[0064] In this embodiment, when the driver is in a state of mild fatigue, playing dynamic music can relieve fatigue to a certain extent, so that the driver can be relaxed to a certain extent. In addition, dynamic music is more likely to excite people, and in the excited state, the driver's fatigue state can be further relieved.

[0065] Further, if Figure 2 As shown, the step of "selectively executing the anti-fatigue driving preset program according to the action information" includes the following: Step S32: When the action information is a moderate fatigue action, turn on the voice assistant.

[0066] In this embodiment, when it is recognized that the driver is showing moderate fatigue, the parking air conditioner automatically turns on the voice assistant, and the voice assistant can interact with the driver verbally. The verbal interaction can improve the driver's attention, thereby allowing the driver to maintain a high level of excitement and reduce fatigue.

[0067] Further, if Figure 2 As shown, the step of "selectively executing the anti-fatigue driving preset program according to the action information" includes the following: Step S33: When the action information is a severe fatigue action, dial a reserved phone number.

[0068] In this embodiment, when it is recognized that the driver is showing severe fatigue, the parking air conditioner directly calls the reserved phone number, which is a must for the driver to get in the car and drive. Calling the reserved phone number allows the driver to communicate with the person he cares about, and through the persuasion of the person he cares about, the driver can be ensured to rest quickly.

[0069] The phone call can be checked after the driver gets in the car and set as an item that requires the driver to confirm. For example, after the driver gets in the car, the driver is required to manually enter the middle four digits of the reserved phone number, and then the parking air conditioner operates normally. Once the driver does not operate according to regulations, an alarm can be sounded to remind the driver.

[0070] Furthermore, the motion information includes one or more of mild fatigue motion, moderate fatigue motion and severe fatigue motion, wherein mild fatigue motion includes yawning and stretching, moderate fatigue motion includes no large movements of both hands within a first set time, and severe fatigue motion includes leaning forward, backward or left or right of the head.

[0071] In this embodiment, mild fatigue actions include yawning and stretching. The camera monitors the driver's actions at all times. Once the driver yawns or stretches, it is determined that the driver is in a mild fatigue state, and dynamic music can be played at this time. When the camera captures the driver's yawning or stretching actions more and more frequently, the volume of the dynamic music increases, and the increase has an upper limit.

[0072] Moderate fatigue actions include no major movements of the driver's hands within the first set time. The camera can capture the driver's head and upper body. When the hands are monitored to have no major movements, and this state of no major work lasts for more than two minutes, it proves that the driver has become accustomed to the excitement brought by dynamic music, and the body has fallen into a more tired state than before. In this state, the driver's thinking ability has slowed down, that is, the reaction ability has slowed down. At this time, the hands are in a state of no movement due to waiting for too long for the instructions transmitted by the brain. In this state, external stimulation is urgently needed to improve the driver's thinking ability, and interactive communication with the outside world is undoubtedly the best factor to stimulate thinking ability. Turn on the voice assistant, and the driver can improve his thinking activity through communication with the voice assistant, so that the driver can more accurately judge that he needs to rest. Among them, the first set time can be 2 minutes.

[0073] Severe fatigue movements include leaning forward, backward, or left or right of the head. When the camera captures the driver's head in an abnormal position, it can be determined that the driver is in a state of severe fatigue. After playing dynamic music and interacting with the voice assistant, the driver still chooses not to rest. Either he is unwilling to rest under the pressure of life and is afraid of delaying making money, or he has not yet reached the service area. Regardless of the reason, in this state, the driver needs to contact important people in his heart, such as relatives. If the driver is unwilling to rest due to the pressure of life, then the persuasion of relatives can play a more effective role, allowing the driver to realize his own safety and importance; if he has not reached the service area, then the communication of relatives can play an incentive role, allowing the driver to insist on reaching the service area more safely.

[0074] Further, if Figure 3 As shown, the control method further includes the following steps:

[0075] Step S4: after the parking air conditioner is started, determining whether the vehicle is in a driving state;

[0076] Step S5: If yes, start timing, otherwise continue to determine whether the vehicle is in a driving state;

[0077] Step S6: Determine whether the timing time exceeds the second set time;

[0078] Step S7: if yes, then intermittently start the aromatherapy system, otherwise determine whether the timing time exceeds the third set time;

[0079] Step S8: If yes, the fresh air system is turned on intermittently, otherwise it is determined whether the timing time exceeds the fourth set time;

[0080] Step S9: If yes, lower the indoor temperature, otherwise continue timing.

[0081] Among them, the second setting time can be 3 hours, the third setting time can be 2.5 hours, and the fourth setting time can be 2 hours.

[0082] In this embodiment, in order to improve the stability of the system and ensure the safety of the driver. The control method provided by the present invention also includes another form of anti-fatigue driving mode, which reminds the driver from the dimension of time and stimulates the technician from the aspects of body sensation and smell. For example, when the driver drives the running vehicle for more than 2 hours, the temperature in the cab is lowered to stimulate the driver's body sense and avoid the driver from being more easily fatigued at a suitable temperature.

[0083] When the driver has been driving the vehicle for more than 2.5 hours, the fresh air system can be turned on intermittently. During the opening process, the fresh air system can replace the indoor air with fresh air from the outside space. Since the oxygen content in the outside space is relatively high, the oxygen supply to the driver's head is greatly improved, which will effectively reduce the driver's fatigue. The intermittent opening method allows the driver to switch between the two working spaces. During the switching process, the human body is more likely to become excited due to the perception of external changes. In addition, the intermittent opening form also takes into account the driving comfort to a certain extent. Once the driving environment is uncomfortable, the driver is prone to irritability, and irritability increases the driver's danger.

[0084] When the driver drives the vehicle for more than 3 hours, the aromatherapy system is turned on intermittently. After the aromatherapy system is turned on, the aromatherapy smell will enter the cab, which will stimulate the driver's sense of smell, increase the driver's excitement, and thus reduce the driver's fatigue. Similarly, the intermittent opening method is not only conducive to increasing the driver's excitement, but also avoids the waste of aromatherapy.

[0085] It should be noted that lowering the indoor temperature, intermittently turning on the fresh air system and intermittently turning on the aromatherapy system can be turned on separately, or any two or three can be turned on at the same time. However, a specific effective method needs to be matched within a specific time period. For example, after driving for more than 3 hours, the aromatherapy system must be turned on because it has a better refreshing effect than the other two forms. Lowering the indoor temperature and intermittently turning on the fresh air system can be turned on or off as appropriate, and an optional method is adopted to allow the driver to choose according to his or her own habits.

[0086] It should be noted that the aromatherapy system is a module set on the parking air conditioner, with aromatherapy placed in the module. The module is connected to the air inlet duct of the parking air conditioner, and an electronic valve is set on the aromatherapy system. Under the control of the parking air conditioner, the valve is in an open or closed state. When the valve is opened, the wind in the air inlet duct will pass through this module and bring the aromatherapy smell in the module into the air inlet duct, and then into the cab.

[0087] Further, the step of "if yes, then lowering the indoor temperature" includes the following: based on the existing indoor temperature, lowering the first set temperature.

[0088] The first set temperature may be 2°C.

[0089] In this embodiment, the temperature is reduced by 2°C on the existing basis to avoid lowering the temperature too low and causing an uncomfortable driving environment for the driver. The indoor temperature is usually adjusted by the driver according to his own needs, and this adjustment will inevitably put the driver in a comfortable environment. Therefore, although the comfort level will be reduced to a certain extent, the driver's safety is greatly improved by reducing the temperature by 2°C on this basis.

[0090] Further, the step of “if yes, then intermittently turning on the fresh air system” includes the following: turning on the fresh air once at intervals of a first preset time, and the turning-on time is a second preset time.

[0091] Among them, the first preset time length is 10 minutes, and the second preset time length is 2 minutes.

[0092] In this embodiment, the opening time is set to 2 minutes. There is no need for a too long ventilation time, but the time should not be too short. If it is too long, it will easily lead to a relatively large change in the comfortable indoor environment, while if it is too short, the ventilation will not have the desired effect.

[0093] Further, the step of “if yes, then intermittently turning on the aromatherapy system” includes the following: turning on the aromatherapy system once at intervals of a third preset time length, and the duration is a fourth preset time length.

[0094] Among them, the third preset time length can be 10 minutes, and the fourth preset time length can be 30 seconds.

[0095] In this embodiment, since the aroma is strong, the time for opening the aroma system should not be too long, and only 30 seconds are needed. Since the aroma is in a normally open state, in order to avoid the aroma in the cab being too strong, an appropriate opening time of the aroma system is adopted.

[0096] like Figure 4 As shown, a control method of an anti-fatigue driving type parking air conditioner comprises the following steps:

[0097] Step M1: Start the parking air conditioner;

[0098] Step M2: Detect and determine whether each module is operating normally;

[0099] Step M3: If yes, obtain the driver's action information, otherwise standby and alarm;

[0100] Step M31: When the motion information is a light fatigue motion, playing dynamic music;

[0101] Step M32: When the action information is a moderate fatigue action, start the voice assistant;

[0102] Step M33: When the action information is a severe fatigue action, dial a reserved phone number;

[0103] Step M4: When each module operates normally, determine whether the vehicle is in a driving state;

[0104] Step M5: If yes, start timing, otherwise continue to determine whether the vehicle is in a driving state;

[0105] Step M6: Determine whether the timing time exceeds the second set time;

[0106] Step M7: if yes, then intermittently start the aromatherapy system, otherwise determine whether the timing time exceeds the third set time;

[0107] Step M8: If yes, then intermittently start the fresh air system, otherwise determine whether the timing time exceeds the fourth set time;

[0108] Step M9: If yes, lower the indoor temperature, otherwise continue timing.

[0109] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
