Description

Technical Field

[0001] The present disclosure relates to a control system for a manual air conditioner for a vehicle, and particularly relates to suppression of energy consumption during execution of remote air conditioning and achievement of a comfortable air conditioning state when a user gets into the vehicle. Background Art

[0002] The following system is described in Japanese Patent Laid-Open No. 2015-74236: When a user operates a remote electronic key in a state of being outside the vehicle, a control unit in the vehicle controls an air conditioning device accordingly to cause the air conditioning device to perform remote air conditioning. In this system, when there is an instruction to execute remote air conditioning, if the outside air temperature is lower than the inside air temperature of the vehicle compartment, ventilation operation is executed, and if the outside air temperature is higher than the inside air temperature of the vehicle compartment, cooling operation is executed.

[0003] In addition, in a manual air conditioner for a vehicle, the blowing temperature and the air volume of the air conditioning wind from the air outlet are manually adjusted by a user operating an operation unit inside the vehicle compartment. In this manual air conditioner, there is no temperature sensor inside the vehicle compartment, and the temperature inside the vehicle compartment cannot be automatically adjusted. Therefore, the air conditioning device is caused to operate at a set blowing temperature and a set air volume corresponding to the operation position when the user last got out of the vehicle by a trigger instruction for remote air conditioning.

[0004] However, in the case of performing remote air conditioning by a manual air conditioner for a vehicle, if the set blowing temperature and the set air volume during weak cooling or heating when getting out of the vehicle are used, the user may sometimes feel insufficient cooling or heating in the vehicle compartment when getting into the vehicle. On the other hand, if the blowing temperature and the air volume are forcibly changed to the maximum and maintained in that state during remote air conditioning, energy will be wasted. In addition, if the blowing temperature and the air volume are maintained at an intermediate temperature and an intermediate air volume during remote air conditioning, it may not be possible to achieve a comfortable temperature inside the vehicle compartment when the user gets into the vehicle after a very short time from the start of remote air conditioning. Summary of the Invention

[0005] An object of the present disclosure is to suppress energy consumption during execution of remote air conditioning and achieve a comfortable air conditioning state when a user gets into the vehicle in a control system for a manual air conditioner for a vehicle.

[0006] The control system of the manual air conditioner for a vehicle according to the present disclosure includes: a manual air conditioner that manually adjusts the blowing temperature and the air volume of the conditioned air from the air outlet by a user operating an operation unit inside the vehicle compartment; and a control device that causes the manual air conditioner to perform remote air conditioning according to an instruction from outside the vehicle when the user has not boarded the vehicle. Wherein, the control device starts the operation of the manual air conditioner with the target blowing temperature of the conditioned air being the maximum temperature and the target air volume of the conditioned air being the maximum air volume according to the trigger instruction of the remote air conditioning, gradually changes the target blowing temperature towards the target intermediate temperature and gradually decreases the target air volume over time, and when it senses that the user has boarded the vehicle, changes the target blowing temperature and the target air volume to the set blowing temperature and the set air volume at the time of the last getting off the vehicle, respectively.

[0007] According to the above configuration, different from the case of continuously maintaining the set blowing temperature and the set air volume with weak cooling or heating during remote air conditioning, it is possible to prevent the user from feeling insufficient cooling or heating in the vehicle compartment when getting on the vehicle. Moreover, during remote air conditioning, the target blowing temperature gradually changes from the maximum temperature towards the target intermediate temperature and the target air volume gradually decreases. The target intermediate temperature can be set to a specified temperature such as 25°C, which is considered the most comfortable for most people. Even when the most comfortable temperature varies according to the user, generally, the user's comfortable temperature is closer to the target intermediate temperature than the maximum temperature. Thus, it is easy to suppress energy consumption and achieve a comfortable temperature inside the vehicle compartment when the user gets on the vehicle as soon as possible. Also, the target blowing temperature and the target air volume when the user gets on the vehicle become the set blowing temperature and the set air volume at the time of the last getting off the vehicle, respectively. Therefore, it is easy to reflect the settings of air conditioning in the recent period and achieve a comfortable air conditioning state corresponding to the user's preferences.

[0008] In the control system of the manual air conditioner for a vehicle according to the present disclosure, it may also be configured as follows: the control device changes the degree of gradual change of the target blowing temperature and the target air volume in the remote air conditioning according to the detection value of at least one of an external air temperature sensor and a sunlight sensor that detects the intensity of sunlight inside the vehicle compartment.

[0009] According to the above configuration, in the case where the temperature inside the vehicle compartment is likely to change according to at least one of the external air temperature and the sunlight intensity, the degree of gradual change of the target blowing temperature and the target air volume is increased, and in the case where the temperature inside the vehicle compartment is not likely to change, the degree of gradual change of the target blowing temperature and the target air volume is decreased. Thus, it is easy to more efficiently achieve a comfortable temperature inside the vehicle compartment when the user gets on the vehicle.

[0010] According to the control system of the manual air conditioner for a vehicle according to the present disclosure, it is possible to suppress energy consumption during remote air conditioning and achieve a comfortable air conditioning state when the user gets on the vehicle.

[0015] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The shapes, numerical values, arrangement relationships, control processes, etc. described below are examples for illustration and can be changed according to the specifications of the control system for the vehicle manual air conditioner. The same components will be denoted by the same reference numerals in the following description. In addition, the control system for the vehicle manual air conditioner according to the embodiment can also be applied to any one of an engine vehicle driven only by an engine, an electric vehicle driven only by an electric motor, and a hybrid vehicle driven by an engine and an electric motor.

[0016] Use Figure 1 to describe the control system 10 for the vehicle manual air conditioner. The control system 10 is configured to include a manual air conditioner 11, an air conditioning control device (air conditioning ECU) 30, an operation panel 40, an outside air temperature sensor 50, a sunlight sensor 51, an on - board sensor 52, and a smart phone 60. The air conditioning control device 30 controls the manual air conditioner 11 based on the operation of the operation unit of the operation panel 40 provided in the vehicle compartment 102 of the vehicle 100 ( Figure 3 ) by the user 90 ( Figure 3 ). Thereby, in the manual air conditioner 11, conditioned air with the blowing temperature and air volume manually adjusted is blown out from the air outlet provided in the vehicle compartment 102.

[0017] Although detailed illustrations are omitted, the manual air conditioner 11 is provided inside the vehicle 100, and one or both of the outside air and the inside air of the passenger compartment are taken into the duct by a blower disposed in the duct and sent to the downstream side. A cooling unit and a heating unit are disposed on the downstream side of the blower, and the mixing ratio of the air passing through the cooling unit and the air passing through the heating unit is adjusted by the operation of an air mixing door, thereby adjusting the temperature. The conditioned air whose temperature has been adjusted is blown out from the air outlet in the passenger compartment.

[0018] The air conditioning control device 30 is configured to include, for example, an arithmetic processing unit composed of a CPU and a storage unit 31 such as a RAM and a ROM. The air conditioning control device 30 operates the manual air conditioner 11 based on the manual operation of the operation unit of the operation panel 40 by the user 90 when the user 90 has boarded the vehicle. Moreover, the air conditioning control device 30 causes the manual air conditioner 11 to perform remote air conditioning according to an instruction from outside the vehicle using the smart phone 60 when the user 90 has not boarded the vehicle.

[0019] Moreover, as will be described later, the set blowing temperature and the set air volume at the time of the last getting off are stored in the storage unit 31 of the air conditioning control device 30. For example, when the ignition switch or the start button of the vehicle, etc., which is a start switch, is turned off (OFF), the set blowing temperature and the set air volume set by the user through the operation of the operation unit of the operation panel 40 are stored in the storage unit 31. The set blowing temperature and the set air volume are used to restore the target blowing temperature and the target air volume of the conditioned air to the set blowing temperature and the set air volume, respectively, when it is detected that the user 90 has boarded the vehicle during remote air conditioning.

[0020] Moreover, the air conditioning control device 30 has a blowing temperature and air volume control unit 32 and a gradient selection unit 33. The blowing temperature and air volume control unit 32 causes the conditioned air targeted at the set blowing temperature and the set air volume to be blown out from the air outlet by controlling the actuators for the blower and the air mixing door of the manual air conditioner 11. The gradient selection unit 33 selects the gradient of the target blowing temperature and the target air volume to be used during remote air conditioning based on the detection values of an outside air temperature sensor 50 and a sunlight sensor 51, which will be described later. Thereby, it is easier to more efficiently achieve a comfortable temperature inside the passenger compartment when the user 90 boards the vehicle.

[0021] The operation panel 40 is arranged near the instrument panel at the front part inside the vehicle compartment 102. The operation panel 40 is provided with: an air volume adjustment switch 41 for setting the target air volume of the blower of the manual air conditioner 11; a temperature adjustment switch 42 for setting the target blowing temperature of the conditioned air blown out from the air outlet; and an A / C on-off switch 43 for switching the on-off of the compressor of the manual air conditioner 11. Each switch 41, 42, 43 of the operation panel 40 corresponds to an operation part. When one or more switches of the operation panel 40 are operated to set the blowing state of the conditioned air from the air outlet, the air conditioning control device 30 controls each drive part such as the blower of the manual air conditioner 11 and the actuator for driving the air mixing door based on this set state. Thereby, conditioned air of a desired air volume adjusted to a desired temperature is blown out from the air outlet. For example, when the highest temperature is set by operating the temperature adjustment switch 42, all the air flowing downstream of the blower in the duct passes through the heating part by the movement of the air mixing door, and then this air is blown out from the air outlet. At this time, the cooling part is stopped from working. On the other hand, when the lowest temperature is set by operating the temperature adjustment switch 42, all the air flowing downstream of the blower in the duct passes through the cooling part and does not pass through the heating part by the movement of the air mixing door, and the cooling part is made to work.

[0022] The outside air temperature sensor 50 detects the outside air temperature of the vehicle 100. The sunlight sensor 51 is arranged near the front window inside the vehicle compartment 102 or the like and detects the intensity of sunlight inside the vehicle compartment 102. The boarding sensor 52 detects that the user 90 has boarded the vehicle 100. For example, the boarding sensor 52 is composed of a door lock sensor, and when the driver's door is unlocked and then locked again, it is determined that the user 90 has boarded. The boarding sensor 52 can also be composed of a door opening and closing sensor, and when the driver's door changes from the closed state to the open state, it is determined that the user 90 has boarded. The boarding sensor 52 can also be composed of a seating sensor for detecting that the user 90 has seated on the driver's seat, and when seating is detected, it is determined that the user 90 has boarded. The detection signals of the outside air temperature sensor 50, the sunlight sensor 51, and the boarding sensor 52 are output to the air conditioning control device 30.

[0023] The smart phone 60 is a remote operation device for the user 90 to indicate remote air conditioning through remote operation before getting on the vehicle. For example, an application for indicating remote air conditioning is pre-installed in the smart phone 60. The user 90 starts this application, thereby executing the program. At this time, for example, the following is displayed on the display screen of the smart phone 60 Figure 1The image of the start button 61 shown. The user 90 touches the start button 61, whereby a trigger signal indicating the trigger instruction for remote air conditioning is sent to the air conditioning control device 30 of the vehicle 100. For example, the trigger signal is sent from the smartphone 60 to the vehicle 100 as a wireless signal such as the WiFi standard, and the air conditioning control device 30 operates the manual air conditioner 11 based on this trigger signal. It should be noted that the remote operation device can also be a portable information terminal such as a tablet terminal other than the smartphone 60, an electronic key, a remote control dedicated to the instruction of remote air conditioning, etc.

[0024] Moreover, the blowing temperature and air volume control unit 32 of the air conditioning control device 30 performs the fade-out and recovery control according to the trigger instruction for remote air conditioning performed by the smartphone 60 or the like. In the fade-out and recovery control, first, the blowing temperature and air volume control unit 32 starts the operation of the manual air conditioner 11 with the target blowing temperature of the air conditioning wind blown out from the air outlet being the maximum temperature and the target air volume of the air conditioning wind being the maximum air volume. This "maximum temperature" refers to either the highest temperature during heating or the lowest temperature during cooling, and is the target temperature set when the Figure 1 temperature adjustment switch 42 shown is operated to the "C" position or the "H" position. The blowing temperature and air volume control unit 32 determines whether to set the maximum temperature as the highest temperature or the lowest temperature based on the detected value of the outside air temperature. More specifically, in a hot situation where the detected value of the outside air temperature is higher than a specified temperature such as 25°C, the blowing temperature and air volume control unit 32 determines that the user 90 has requested cooling, and sets the target blowing temperature of the air conditioning wind to the lowest temperature. On the other hand, in a cool or cold situation where the outside air temperature is below the specified temperature, the blowing temperature and air volume control unit 32 determines that the user 90 has requested heating, and sets the target blowing temperature of the air conditioning wind to the highest temperature.

[0025] Then, the air temperature and air volume control unit 32 gradually changes the target air temperature toward the target intermediate temperature and gradually decreases the target air volume toward the minimum air volume during remote air conditioning as time passes. The "target intermediate temperature" can be set to a temperature that is considered to be the most comfortable for most people, such as a specified temperature such as 25°C, and is pre-stored in the storage unit 31 of the air conditioning control device 30. In this way, from the state where the target air temperature is set to the maximum temperature and the target air volume is set to the maximum air volume at the start of remote air conditioning, the target air temperature is gradually changed toward the target intermediate temperature and the target air volume is gradually decreased, so that energy consumption can be suppressed and the temperature in the vehicle compartment 102 can be brought close to a comfortable temperature as soon as possible. The minimum air volume during remote air conditioning is, for example, a specified intermediate air volume. When the target air volume of the air conditioning wind reaches the minimum air volume during remote air conditioning, the target air volume is maintained in this state until a passenger is detected to board the vehicle. In addition, when the target air temperature of the air conditioning wind reaches the target intermediate temperature, the target air temperature is maintained in this state until a passenger is detected to board the vehicle.

[0026] Then, when the blowing temperature and air volume control unit 32 senses that the user 90 has boarded the vehicle, the target blowing temperature and target air volume are respectively changed to the set blowing temperature and set air volume set by the operation of the user 90 when the user last boarded the vehicle. Thus, a comfortable air conditioning state corresponding to the preference of the user 90 can be easily achieved.

[0027] In addition, the gradient selection unit 33 of the air conditioning control device 30 changes the gradient of each specified time when the target blowing temperature is gradually changed toward the target intermediate temperature and the target air volume is gradually decreased according to the detection values ​​of the external temperature sensor 50 and the sunshine sensor 51. Thus, in the case where the temperature in the cabin 102 is easy to change according to the external temperature and the sunshine intensity, the gradient of the target blowing temperature and the target air volume is increased. In addition, in the case where the temperature in the cabin 102 is not easy to change according to the external temperature and the sunshine intensity, the gradient of the target blowing temperature and the target air volume is reduced. Thus, in combination with changing the gradient using both the external temperature and the sunshine intensity, it is easy to more efficiently achieve a comfortable cabin temperature when the user 90 gets on the bus. It should be noted that the air conditioning control device 30 can also be configured to change the gradient according to the detection value of one of the sensors, the external temperature sensor 50 and the sunshine sensor 51. Furthermore, the air conditioning control device 30 may not include a gradual change degree selection unit, and the gradual change degrees of the target blowing temperature and the target air volume may be set to predetermined values ​​regardless of the outside air temperature and the sunlight intensity.

[0028] use Figure 2 The flowchart of FIG. 1 illustrates the remote air conditioning control method performed by the air conditioning control device 30. First, Figure 2In step S1, it is determined whether there is a trigger indication for remote air conditioning through the operation of the smartphone 60. When the determination result in step S1 is affirmative (yes), that is, when it is determined that there is a trigger indication, the process moves to step S2. When the determination result in step S1 is negative (no), that is, when it is determined that there is no trigger indication, the process returns to before step S1.

[0029] In step S2, the degree of gradual change is set when the target blowing temperature gradually changes from the maximum temperature and the target air volume gradually decreases from the maximum air volume in remote air conditioning. Specifically, the degree of gradual change of the target blowing temperature and the target air volume is selected according to the detection values of the external air temperature sensor 50 and the sunlight sensor 51. For example, during cooling, when at least one of the external air temperature and the sunlight intensity is higher than their respective corresponding specified values, that is, in a hot situation, the temperature inside the passenger compartment 102 is not easily changed by the operation of the manual air conditioner 11, so the degree of gradual change of the target blowing temperature and the target air volume is reduced. On the other hand, during cooling, when both the external air temperature and the sunlight intensity are below their respective corresponding specified values, the temperature inside the passenger compartment 102 is easily changed by the operation of the manual air conditioner 11, so the degree of gradual change of the target blowing temperature and the target air volume is increased.

[0030] Next, in steps S3 to S6, the blower is operated to blow conditioned air from the air outlet. At this time, one or both of the cooling device and the heating device of the manual air conditioner 11 are operated. First, in step S3, the target blowing temperature and the target air volume are set to the maximum respectively to start the remote air conditioning by the operation of the manual air conditioner 11. At this time, in an engine vehicle, the engine is operated at an idle speed, and the generator is driven to supplement the charging power of the battery consumed in the operation of the manual air conditioner 11. The temperature of the heater core used for temperature adjustment of the conditioned air is increased by the operation of the engine. It should be noted that the temperature of the heater core can also be increased by driving the drive motor, or as an electric heater, the temperature can be increased by supplying power to the electric heater. Then, in step S4, the manual air conditioner 11 is operated in such a way that the target blowing temperature gradually changes toward the target intermediate temperature and the target air volume gradually decreases toward the minimum air volume during remote air conditioning. For example, during cooling, the target blowing temperature gradually increases from the lowest temperature toward the target intermediate temperature according to the degree of gradual change selected in step S2. On the other hand, during heating, the target blowing temperature gradually decreases from the highest temperature toward the target intermediate temperature according to the selected degree of gradual change. Thus, different from the case of continuously maintaining the set blowing temperature and set air volume of weak cooling or heating during remote air conditioning, it is possible to prevent the user 90 from feeling insufficient cooling or heating in the vehicle compartment when getting on the vehicle. Moreover, as described above, the target intermediate temperature can be set to a specified temperature such as 25°C, which is considered the most comfortable for most people. Even when the most comfortable temperature varies according to the user, generally, the comfortable temperature of the user is closer to the target intermediate temperature than the maximum temperature. Thus, it is easy to suppress energy consumption and achieve a comfortable temperature inside the vehicle compartment for the user 90 when getting on the vehicle as soon as possible.

[0031] Next, in step S5, it is determined whether the user 90 is sensed as getting on the vehicle based on the detection signal of the on-vehicle sensor 52. If the determination result in step S5 is negative (No), that is, the user getting on the vehicle is not sensed, the process returns to before step S4. On the other hand, if the determination result in step S5 is positive (Yes), that is, the user getting on the vehicle is sensed, the target blowing temperature and the target air volume are changed to restore the set blowing temperature and set air volume at the time of the last getting off (step S6), and this state is maintained. This state is maintained until the user 90 operates the air volume adjustment switch 41 or the temperature adjustment switch 42, and the control of the remote air conditioning is ended by the operation of any one of the switches. In this way, the target blowing temperature and the target air volume when the user 90 gets on the vehicle are respectively the set blowing temperature and set air volume at the time of the last getting off, so it is easy to reflect the settings of the air conditioning near the time and achieve a comfortable air conditioning state corresponding to the user's preferences.

[0032] According to the control system 10 of the manual air conditioner described above, it is possible to prevent the user 90 from feeling insufficient cooling or heating in the passenger compartment 102 when getting into the vehicle. Moreover, it is easy to suppress energy consumption and achieve a comfortable in-vehicle temperature for the user 90 as early as possible when getting into the vehicle. Moreover, it is easy to achieve a comfortable air-conditioning state corresponding to the preferences of the user 90. Thus, it is possible to suppress energy consumption during remote air conditioning and achieve a comfortable air-conditioning state for the user 90 when getting into the vehicle.

[0033] Figure 3 The relationship between the in-vehicle temperature and time is used to show the effect achieved by remote air conditioning during cooling in the embodiment. The user 90 operates the smartphone 60, whereby a trigger instruction for remote air conditioning is sent to the air-conditioning control device 30, and remote air conditioning starts. Thus, as Figure 3 shown by the solid line a, the in-vehicle temperature gradually decreases from the initial high temperature in a manner converging towards the vicinity of the target intermediate temperature. Then, in the case where the user 90 gets into the vehicle before the in-vehicle temperature reaches the vicinity of the target intermediate temperature, the target blowing temperature and the target air volume are respectively restored to the set blowing temperature and the set air volume at the time of the last getting off. Therefore, as Figure 3 shown by the solid line b, the in-vehicle temperature changes in a manner converging towards the vicinity of the set blowing temperature at the time of the last getting off, so the solid line a and the solid line b representing the in-vehicle temperature form a curve with the point P1 at the time of getting into the vehicle as the inflection point. In Figure 3 , the following situation is shown: at the time of the last getting off, the user 90 operates the temperature adjustment switch 42 to make the set blowing temperature higher than the intermediate temperature, that is, set to weaker cooling.

[0034] On the other hand, in Figure 3 , the situation where the user 90 does not perform remote air conditioning before getting into the vehicle is shown by the dashed line c. In this case, when the user 90 gets into the vehicle, the in-vehicle temperature is high, similarly to the start of remote air conditioning of the solid line a. In addition, in this case, after the user 90 gets into the vehicle, the manual air conditioner 11 starts normal operation that is not remote air conditioning by operating the start switch and the like. Through Figure 3 comparison of the in-vehicle temperature with and without remote air conditioning, it can be seen that in the case of performing remote air conditioning, when getting into the vehicle, compared with the case without remote air conditioning, the in-vehicle temperature can be reduced by the temperature difference indicated by the hollow arrow d, and the discomfort of the user 90 when getting into the vehicle can be reduced.

[0035] Figure 4 The relationship between the in-vehicle temperature and time is used to show the effect achieved by remote air conditioning during heating in the embodiment. In Figure 4 the example, when remote air conditioning starts by the operation of the user 90 on the smartphone 60, as Figure 4As shown by the solid line e, the temperature inside the vehicle compartment gradually rises from the initial low temperature in a manner that converges near the target intermediate temperature. Then, in the case where the user 90 has boarded the vehicle before the temperature inside the vehicle compartment reaches near the target intermediate temperature, the target blowing temperature and the target air volume are respectively restored to the set blowing temperature and the set air volume at the time of the previous disembarkation. Therefore, as Figure 4 shown by the solid line f in, the temperature inside the vehicle compartment changes in a manner that converges near the set blowing temperature at the time of the previous disembarkation. Therefore, the solid line e and the solid line f representing the temperature inside the vehicle compartment form a curve with the boarding point P2 as the inflection point. In Figure 4 , the following situation is shown: at the time of the previous disembarkation, the user 90 operated the temperature adjustment switch 42 to make the set blowing temperature lower than the intermediate temperature, that is, set to weaker heating.

[0036] On the other hand, in Figure 4 , the case where the user 90 did not perform remote air conditioning before boarding is shown by the dashed line g. In this case, when the user 90 boards the vehicle, the temperature inside the vehicle compartment is low, just like at the start of the remote air conditioning of the solid line e. From this, it can be known that in the case of performing remote air conditioning, when boarding the vehicle, compared with the case of no remote air conditioning, the temperature inside the vehicle compartment can be increased by the temperature difference indicated by the hollow arrow h, and the discomfort of the user 90 when boarding the vehicle can be reduced.

[0037] This application claims the priority of Japanese Patent Application No. 2021-23576 filed on February 17, 2021, which is incorporated herein.
