  2. Description of the Related Art Conventionally, in a vehicle air conditioner, a technique for reducing the driving load of an air conditioning compressor on a vehicle engine and ensuring the acceleration of the engine is known (for example, see Patent Document 1).

JP 2003-285618 A

  Therefore, even when the engine load becomes large, such as when driving on a hill or when merging along a parallel road, the compressor load of the air conditioner is applied to the engine as it is until the actual accelerator depression exceeds a predetermined threshold, which impairs driving feeling. There was a possibility. The same applies to a vehicle such as a hybrid vehicle that uses a motor as a power source. That is, when the load state of the power source becomes large, there is a possibility that the in-vehicle power source becomes overloaded by the electric load due to the electric compressor of the air conditioner being directly applied to the in-vehicle power source. When the in-vehicle power supply becomes overloaded, the motor output decreases. Therefore, there is a possibility of impairing driving feeling.

(Overall configuration of vehicle air conditioner)
FIG. 1 is a configuration diagram showing the overall configuration of a vehicle air conditioner, and FIG. 2 is a cross-sectional view of a main part of a regenerator 40.

  In FIG. 1, the vehicle air conditioner includes an air conditioner 100 mainly composed of a mechanical configuration, and an air conditioner control device 50 that is a control unit of the air conditioner 100.

  First, the configuration of the air conditioner 100 will be described. The refrigeration cycle R of the air conditioner has a compressor 1. The compressor 1 includes an electromagnetic clutch 2 for power interruption that is transmitted from an in-vehicle engine 4 via a belt 3. The refrigeration cycle R is constituted by a closed circuit, and the closed circuit includes a condenser 5, a receiver 6, a temperature expansion valve 7 having a temperature sensing unit 8, and an evaporator 9 counterclockwise from the compressor 1.

  In the air conditioning case 10 of the air conditioner 100, a blower fan 11 is disposed on the upstream side of the evaporator 9. The blower fan 11 has a centrifugal blower fan 12 and a drive motor 13. An inside / outside air switching box 14 is disposed on the suction side of the blower fan 11. Inside / outside air switching box 14 is arranged inside / outside air switching door 15 driven by electric drive unit 18. The inside / outside air switching door 15 opens and closes by switching between the outside air introduction port 16 and the inside air introduction port 17.

  On the downstream side of the evaporator 9, a regenerator 40, an air mix door 19, and a heater core 20, which will be described later, are arranged in order from the evaporator side. A bypass passage 21 that bypasses the heater core 20 is formed. The air mix door 19 is rotated by the electric drive device 22 to adjust the air volume ratio between the hot air from the passage 23 passing through the heater core 20 and the cold air passing through the bypass passage 21.

  Further, a blow-out mode switching unit 15 is configured in the air conditioning case 10 on the downstream side of the air mixing unit 24. The blowing mode switching unit 15 includes a defroster opening (DEF) 25 and its defroster door 26, a face opening (FACE) 27 and its face door 28, and a foot opening 29 (FOOT) and its foot door 30. The Each opening is opened and closed by each door 26, 28, 30 driven by the electric drive device 31.

  The temperature sensor 32 of the evaporator 9 detects the evaporator outlet temperature Te as the evaporator temperature. The temperature sensor 33 of the regenerator 40 detects the regenerator outlet temperature Tc as the regenerator temperature.

  In addition to the evaporator blowout temperature Te and the regenerator blowout temperature Tc of the temperature sensors 32 and 33, the air conditioning control device 50 includes an internal air temperature Tr, an external air temperature Tam, a solar radiation amount Ts, a hot water temperature Tw, Various information such as the set temperature indicated by the occupant and the like are input from the air conditioning information unit 35. In addition, the air conditioning control device 50 has a vehicle information unit 36 that gives the driver's feet to the engine speed, the vehicle speed, the transmission shift position, the brake depression amount, the accelerator depression amount, and either the accelerator pedal or the brake pedal of the vehicle. Various vehicle information such as a foot position indicating whether or not there is input. Further, the air conditioning control device 50 has an external environment (outside of the vehicle) road conditions captured by the in-vehicle camera and the in-vehicle radar device in order to objectively show the vehicle operation from the external information unit 37, for example, the inter-vehicle distance to the other vehicles before and after, , The road information obtained by the in-vehicle navigation device, for example, various information such as the distance to the next intersection and the road gradient of the route are input. Here, the air-conditioning information unit 35 and the vehicle information unit 36 function as a driver action detection unit that detects the operation amount of the driver. They detect the set temperature, vehicle speed, foot position, etc. as the driver's operation amount. The vehicle information unit 36 also functions as a vehicle operation detection unit that detects the movement of the vehicle together with the external information unit 37. They detect the above road conditions, road information, etc. as vehicle operation information.

  The air-conditioning control device 50 includes one or a plurality of microcomputers (not shown) composed of a CPU, ROM, RAM, etc. (not shown), peripheral circuits thereof, and storage means such as an electrically rewritable nonvolatile memory. 51.

  The air-conditioning control device 50 includes a driving action intention estimation unit 52, a determination unit 53, and an air-conditioning control unit 54 as function implementing units using the microcomputer.

The air conditioning control means 54 drives the air conditioning equipment 100 including the compressor 1 to control the air conditioning state in the passenger compartment.

(Configuration of regenerator 40)
Next, a specific configuration example of the regenerator 40 will be described with reference to FIG.
The regenerator 40 has a shape having the same front surface area as the evaporator 9 shown in FIG. In addition, the regenerator 40 has a heat exchanger configuration through which the entire amount of cold air after passing through the evaporator 9 passes in order to exhibit cooling capacity that can be used during air conditioning. With this configuration, the regenerator 40 can have a thin structure with a small thickness dimension with respect to the flow direction A in the air conditioning case 10. In addition, convex portions 41a and 42a are alternately formed along the cold air flow direction A on the two aluminum heat transfer plates 41 and 42, respectively. The convex portions 41a and 42a are brought into contact with each other and joined by brazing or the like.

  Thereby, the tube 45 which has the sealed space 43 inside the convex surface parts 41a and 42a is formed. And the cool storage material 44 is accommodated in the sealed space 43. In this example, a paraffin having a freezing point of about 8 ° C. is selected as the regenerator material 44 as a material having a freezing point within the fluctuation range (1 to 12 ° C.) of the evaporator temperature Te.

Therefore, the air passage 46 forms a meandering passage by the convex portions 41 a and 42 a protruding alternately, and the heat transfer rate from the cold air side to the tube 45 is improved.
Although only two sets of tubes 45 are shown in FIG. 2, a large number of tubes 45 are actually stacked in the direction of arrow B in FIG.

  Here, the cold storage behavior according to the present embodiment will be described. The air conditioner cools the air blown from the blower fan 11 by the evaporator 9. Thereafter, the air conditioner adjusts the opening degree of the air mix door 19 to mix the cold air and the hot air, thereby controlling the temperature of the air into the passenger compartment to the target air temperature TAO. In that case, for example, even if it is a relatively high temperature of TAO = 12 ° C., it is necessary to set the target evaporator temperature Teo as low as possible in order to complete the cool storage of the regenerator 40 in a short time.

  However, since the evaporator 9 is frosted at 0 ° C. or lower, the minimum temperature (Min) of the target evaporator temperature Teo1 is about 1 ° C. Moreover, since the freezing point of paraffin which is the cold storage material 44 is 8 ° C., in order to perform rapid cold storage, the target evaporator temperature Teo11 is lower than 8 ° C. and higher than the minimum temperature in order to maintain cold storage after completion of cold storage, for example, 6 ° C is required. At the time of cooling, setting of the target evaporator temperature is not necessary when the compressor 1 is stopped, but the temperature of the regenerator 40 rises due to cooling and the limit regenerator temperature Tco for determining the limit and stop of the cooling. For example, a setting of 12 ° C. is required.

(Basic operation of air conditioner)
Next, the basic operation of the air conditioner by the air conditioning control device 50 will be described. FIG. 3 is a flowchart of a main routine of air conditioning control processing (air conditioning control means 54) executed in the air conditioning control device 50.

  As shown in FIG. 3, when an ignition switch (not shown) is turned on and this routine is started, the air conditioning control device 50 first initializes the stored contents of the data processing memory (RAM) (step 101). ). Subsequently, the air conditioning control device 50 receives various signals (evaporator temperature Te, regenerator temperature Tc, inside air temperature Tr, outside air temperature Tam, solar radiation amount Ts, hot water temperature Tw, and set temperature Tl indicated by the occupant from the air conditioning information unit 35 and the like. , Etc.) and instruction information relating to cold storage, cooling and the like from the determination means 53 described later are read (step 102).

  Subsequently, the air-conditioning control device 50 calculates the necessary blowout temperature TAO corresponding to the thermal load of the vehicle based on various signals (step 103).

  Next, the air-conditioning control device 50 selects an air-conditioning mode based on instruction information from the determination unit 53 described later (step 104). When the normal mode is selected, the air conditioning control device 50 determines the target evaporator temperature Teo in the normal mode (step 105). This target evaporator temperature Teo is a target value determined by air-conditioning environment conditions such as the outside air temperature Tam in order to reduce the operating rate of the compressor 1 and save power of the engine 4. For example, when the outside air temperature is in the range of 18 to 25 ° C. as in the spring / autumn season, the target evaporator temperature Teo is set to 12 ° C. in order to suppress the useless operation of the refrigeration cycle due to the operation of the compressor 1. On the other hand, when the outside air temperature is less than 18 ° C. or higher than 25 ° C., the target evaporator temperature Teo is set low.

  When the cold storage mode is selected, the air conditioning controller 50 determines the target evaporator temperature Teo1 in the cold storage mode (step 106). When the cool-down mode is selected, the air-conditioning control device 50 sets the limit regenerator temperature Tco indicating that the temperature Tc of the regenerator 40 has risen and the cold storage capacity is lost to the target evaporator temperature Teo (step 107). . These target evaporator temperatures Teo, Teo1 and the limit regenerator temperature Tco are stored in the ROM or the storage means 51.

  Subsequently, the blower control voltage (the amount of blown air) is determined based on the required blowing temperature TAO calculated in step 103 (step 108). Also, the blowing mode for switching between the inside air and the outside air is determined based on the required blowing temperature TAO when not manually set (step 109). Further, the outlet mode is determined in the same manner (step 110).

  Subsequently, the opening degree of the air mix door 19 is determined in accordance with a predetermined control characteristic table from the calculated required blowing temperature TAO (step 111). Further, on / off of the compressor 1 is determined in accordance with the condition such as the cooling load (step 112). And the air-conditioning control apparatus 50 controls each apparatus according to the processing result of each step 105-112, and controls to a desired air-conditioning state (step 113).

(Function of the driving action intention estimation means 52)
Next, the driving behavior intention estimation means 52 and the determination means 53 that estimate the driver's behavior intention and instruct the air-conditioning control means 54 to store or cool, will be described with reference to the drawings.

FIG. 4 is a functional block diagram showing main functions of the driving action intention estimation means 52 and the determination means 53 in the air conditioning control device 50.
In FIG. 4, a driving action intention estimation means 52 is a means for estimating a driving action (braking or acceleration) to be performed at an earlier time point when the driver actually brakes or accelerates the vehicle. The driving action intention estimation unit 52 includes a normalization unit 521, a driving action storage unit 522, a driving pattern storage unit 523, and a similarity calculation unit 524. The normalization unit 521 normalizes a plurality of pieces of detection information (driver's operation amount) acquired from the air conditioning information unit 35 and the vehicle information unit 36 that function as driver behavior detection means. Based on the normalized detection information, the driving behavior storage unit 522 always updates and stores the latest normalized detection information during the past fixed period. The operation pattern storage unit 523 stores an operation pattern for increasing braking or engine output. The similarity calculation unit 524 compares the latest normalization detection information stored in the driving behavior storage unit 522 with the driving pattern stored in the driving pattern storage unit 523, and calculates the similarity. Then, the driving pattern having the highest similarity is obtained, and the driver's intention of action (acceleration or braking) after the estimation is estimated based on the driving pattern.

  As detection information (driver's operation amount) for estimation, for example, an accelerator depression amount 36a from an accelerator sensor that detects the depression level of an accelerator pedal, vehicle speed information 36e from a vehicle speed sensor, and engine rotation from a rotation sensor The numerical information 36f can be used. However, the operation amount of the driver is not limited to the above. For example, air conditioning information 35b such as detection information indicating a set temperature Tl or cooling load indicated by the driver, a foot position detection camera (or radar) that detects whether the driver's foot is on the accelerator pedal or the brake pedal. ) From the gear position information 36d from the gear position sensor for detecting the transmission gear position of the transmission, and the like can also be used as the operation amount of the driver.

The operation of the driving action intention estimation means 52 will be described with reference to FIGS.
The driving action intention estimation means 52 reads various detection information as the operation amount of the driver from the air conditioning information part 35 and the vehicle information part 36 that function as the driver action detection means (step 201). Next, the normalization unit 521 normalizes each information according to the level and stage of the information. The normalized information is converted into a numerical value within a range of 0 to 1 as normalized detection information (step 202). Each normalization detection information is memorize | stored in the driving action memory | storage part 522 sequentially in time series as sampling data. Each normalization detection information is sampling data for the latest past fixed period, for example, 5 seconds, and is constantly updated and stored (step 203). The driving behavior storage unit 522 is configured by a RAM in the air conditioning control device 50 or a part of the storage unit 51.

  The similarity calculation unit 524 acquires the latest sampling data (latest driving behavior data) stored in the driving behavior storage unit 522 at predetermined time intervals, for example, every second. The similarity calculation unit 524 compares the acquired sampling data with each operation pattern template stored in the operation pattern storage unit 523. Then, the similarity calculation unit 524 calculates the similarity based on the degree of matching between the two. Details of the driving pattern template will be described later.

  The similarity is 1 when each sampling data completely matches any of the driving pattern templates, and decreases as the difference from the driving pattern template increases. Then, the similarity calculation unit 524 detects an operation pattern template having the highest similarity. The detected driving pattern template is used as behavior intention estimation information for estimating subsequent driver behavior. The detected driving pattern template and the similarity related to the template are stored in the storage means 51 (step 204).

Here, an operation pattern template stored in advance in an operation pattern storage unit 523 constituted by a part of the ROM or the storage means 51 will be described with reference to FIG.
The driving pattern template is created in advance by experiments. The driving pattern template is created as follows, taking braking as an example. Various types of detection information (accelerator depression amount, air conditioning information, foot position, gear position, vehicle speed, engine speed) relating to the operation amount of 100 drivers are collected. For example, for various types of detection information, data for 10 seconds from 10 seconds before the start of the braking operation until the start of the braking operation is detected and normalized. The normalized data (normalized information) is classified using a clustering method. And the driving | operation pattern template of braking action is calculated | required as each classified cluster (data set of the same kind).

Further, each driving pattern template has a plurality of behavior pattern templates for each detection information. The behavior pattern template is created as follows. First, an average value (data for 10 seconds) of normalized data of various detection information corresponding to the driving pattern template is obtained. A plurality of action pattern templates are created by acquiring 5 seconds of data out of each 10 seconds of normalized data by shifting by 1 second.
Similarly, in order to create a driving pattern template for accelerating action, various data relating to the amount of operation of the driver for 10 seconds from the start of the accelerating action 10 seconds to the start of the accelerating action are detected and normalized. Thereafter, using the clustering method in the same manner as described above, a plurality of acceleration pattern driving pattern templates are created.

  FIG. 6 shows each cluster in which the driving pattern template of the braking action is classified into, for example, a double-stepping type, a sudden braking type, and the like, which are braking action patterns, and each cluster further includes detection information (accelerator). Each stepping amount,...) Includes six 5-second data (behavior pattern templates) cut out by shifting by 1 second as a set.

  The similarity calculation unit 524 calculates the similarity between the driving pattern template and the measured sampling data as follows, for example. First, the similarity calculation unit 524 performs matching between sampling data and each behavior pattern template for each detection information, and obtains the highest degree of matching for each detection information. Then, the similarity calculation unit 524 calculates the similarity by multiplying the highest matching degrees obtained for each detection information.

(Function of determination means 53)
Next, in FIG. 4, the determination unit 53 is similar to the plurality of detection information (vehicle operation information) acquired from the vehicle information unit 36 and the outside world information unit 37 that function as the vehicle operation detection unit and the driving action intention estimation unit 52. In response to the degree information, using the detection information different from the detection information used by the driving action intention estimation means 52, the credibility of the similarity obtained previously is evaluated.

  That is, the determination unit 53 includes a certainty factor calculation unit 531, a target evaporator temperature calculation unit 532, an output template storage unit 533, and an output determination unit 534. And the certainty factor calculation part 531 calculates the certainty factor which shows the certainty of a driver | operator's action intention. Further, the output template storage unit 533 stores control characteristic values for achieving both driving feeling and an air conditioning state. The target evaporator temperature calculation unit 532 is based on the similarity information, the behavior intention estimation information, the air conditioning state, the evaporator temperature Te, the regenerator temperature Tc, and the engine output state, according to the control characteristic value from the output template storage unit 533. The target evaporator temperature Teo or the target evaporator temperature Teo1 in the cold storage mode is calculated. The output determination unit 534 receives each information of the driver's accelerator depression amount, certainty factor, and target evaporator temperature Teo or Teo1, and gives instruction information (for example, a cold storage instruction signal or a cooling instruction signal) to the air conditioning control means 54. And provide target evaporator temperature information Teo or Teo1.

  The regenerator 40 can store not only when actually braking, but also during a period immediately before the driver actually brakes the vehicle. Therefore, the air conditioning load (compressor load) on the engine is reduced. Alternatively, the regenerator 40 cools for a period immediately before the driver actually accelerates the vehicle, and cools at the time of actual acceleration. Therefore, the air conditioning load (compressor load) on the engine is reduced.

  As detection information (vehicle operation information) used in the determination means 53, road information ahead of the host vehicle acquired from the car navigation device 37c that provides route guidance to the driver, or a road ahead of the vehicle mounted on the vehicle, Video information (road conditions) acquired from the camera 37a and the radar device 37b that captures the rear road or the side can be used. However, the vehicle operation information used is not limited to the above. For example, the brake depression amount 36b acquired from the brake sensor that detects the depression level of the brake pedal, the traffic jam information acquired from the car navigation device 37c, road gradient information, altitude information, and the like can also be used as the vehicle operation information.

Below, the operation | movement of each part 531,532,534 which comprises the determination means 53 is demonstrated.
First, the certainty factor calculation unit 531 reads the similarity information obtained by the similarity calculation unit 524 as shown in FIG. 7 (step 301).

  Subsequently, the certainty factor calculation unit 531 acquires vehicle operation information from the vehicle information unit 36 and the outside world information unit 37 that function as vehicle operation detection means (step 302). Based on the vehicle operation information, for example, the current vehicle The distance from the position to the next intersection, the distance from the current vehicle position to the nearest specific object (for example, the junction of the expressway), or the road gradient of the nearest path that will proceed from the current vehicle position in the future is obtained. Then, by synthesizing the obtained information and the behavior intention estimation information, the certainty factor calculation unit 531 obtains an inference value indicating the probability that the driver will most recently perform the braking action or the acceleration action using, for example, fuzzy reasoning.

When using fuzzy inference, the certainty factor calculation unit 531 uses each information of the distance to the next intersection, the distance to the specific object, and the road gradient as elements, and members predetermined for each element are used. It has a ship function (fuzzy set). A plurality of membership functions may be set for one element. The membership function of each element is set separately depending on whether the driver's action is acceleration or braking.
When obtaining the behavior intention estimation information, the certainty factor calculation unit 531 selects a membership function of each element based on the driver's behavior (acceleration or braking) indicated in the information. Next, the certainty factor calculation unit 531 calculates the conformity (output value of the membership function) of the fuzzy set of each element based on the measured value of each information. Thereafter, the certainty factor calculation unit 531 calculates the center of gravity of the union of the fitness values based on the min-max method. The calculated value of the center of gravity is an inference value. Note that the certainty factor calculation unit 531 may use an algebraic product-addition centroid method or simplified reasoning instead of using the min-max method.
The inference value may be obtained by a method other than fuzzy inference, for example, a function having the above information as an input variable and the inference value as an output variable. Such a function can be obtained in advance by experiments.

  In the case of acceleration action, for example, the inference value becomes higher when the distance to the next intersection and the distance to the specific object are longer, and when the road gradient is higher. In addition, in the case of braking action, the inference value becomes higher as the distance to the next intersection and the distance to the specific object are closer, and when the road gradient is down.

  The certainty factor calculation unit 531 calculates the certainty factor indicating the certainty of the braking action or the acceleration action of the vehicle by, for example, multiplying both from the inferred value and the similarity degree. Alternatively, the certainty factor calculation unit 531 may directly use the similarity value as the certainty factor when the inference value is equal to or greater than a predetermined value (for example, 0.5). Since the inference value and the similarity are represented by 0 to 1, the certainty factor is also represented by a value in the range of 0 to 1. The calculated certainty factor is stored in the storage means 51 (step 303).

  As shown in FIG. 8, the target evaporator temperature calculation unit 532 includes similarity information obtained by the similarity calculation unit 524, air conditioning information and evaporator temperature Te indicating the air conditioning load state, and engine speed 36f indicating the engine output state, The accelerator depression amount 36a is read (step 401). If the target evaporator temperature calculation unit 532 determines in step 402 that there is a possibility that the driver will perform a braking action based on the action intention estimation information, the process proceeds to step 403.

  The output template storage unit 533 includes an output template for improving driving feeling slightly before and during braking. The output template depends on the engine output state determined from the accelerator depression amount and the engine speed and the current evaporator temperature (correlated to the air conditioning load or compressor load) for a braking state such as gentle braking or sudden braking, for example. Thus, the target evaporator temperature Teo or Teo1 is determined so that the engine output (or engine load) does not change suddenly.

  In step 403, the target evaporator temperature calculation unit 532 reads the output template corresponding to the current braking time and the braking state. Then, the target evaporator temperature calculation unit 532 calculates the target evaporator temperature Teo1 determined by this output template and stores it in the storage unit 51. For example, the target evaporator temperature calculation unit 532 sets the air conditioning load to a relatively low level so as not to give an uncomfortable feeling to the driving feeling while accumulating during a period of time slightly before braking and a moderate actual braking immediately before braking. The target evaporator temperature Teo is set to 3 to 8 ° C. Further, during normal braking and sudden braking, although the air conditioning load increases because cold storage is prioritized over driving feeling, the target evaporator temperature calculation unit 532 sets the target evaporator temperature Teo1 to the minimum temperature (Min) of 1 ° C.

  On the other hand, if the target evaporator temperature calculation unit 532 determines in step 402 that there is a possibility that the driver will take acceleration action based on the action intention estimation information, the process proceeds to step 404. For example, when the driving template having the highest similarity corresponds to the acceleration action, it is determined that there is a possibility of causing the acceleration action.

  The output template storage unit 533 also includes an output template for improving driving feeling immediately before and during acceleration. The output template is, for example, an acceleration state such as moderate acceleration or sudden acceleration, depending on the engine output state obtained from the accelerator depression amount and the engine speed, and the current evaporator temperature (correlated to the air conditioning load) Te. A target evaporator temperature Teo1 is determined so that the engine output (or engine load) does not change suddenly.

  In step 404, the target evaporator temperature calculation unit 532 reads the output template corresponding to the acceleration state immediately before the acceleration and the acceleration state. Further, the target evaporator temperature calculation unit 532 calculates and stores the target evaporator temperature Teo1 determined by this output template. For example, the target evaporator temperature calculation unit 532 sets the target evaporator temperature Teo1 to 3 to 8 ° C. in order to perform cold storage during a period from when the acceleration action is estimated immediately before acceleration to when the acceleration action is actually performed. . Whether the target evaporator temperature calculation unit 532 sets the target evaporator temperature Teo to the maximum temperature of 12 ° C. during actual acceleration behavior, for example, during moderate acceleration, normal acceleration, or sudden acceleration. Alternatively, it is not set (open) to stop the refrigeration cycle R (mainly the compressor 1).

As shown in FIG. 9, the output determination unit 534 reads various detection information (accelerator depression amount 36a, certainty factor, target evaporator temperature Teo or Teo1, regenerator temperature Tc) (step 501). If the output determination unit 534 determines in step 502 that the accelerator depression amount is equal to or less than the first threshold value, the process proceeds to step 503. Thereafter, when the certainty factor read from the certainty factor calculating unit 531 is larger than the second threshold value, the output determining unit 534 determines that it is immediately before braking or during braking, and proceeds to step 504 to read the cold storage instruction signal and the previous one. The target evaporator temperature information Teo1 is output. Alternatively, in step 504, the output determination unit 534 may set the target evaporator temperature higher than Teo1 and output the target evaporator temperature and the cold storage instruction signal. Thereafter, the output determination unit 534 may decrease the target evaporator temperature in a stepwise manner until the target evaporator temperature becomes equal to Teo1 when the actual braking action occurs.
When the read certainty factor is equal to or lower than the second threshold value, the output determination unit 534 outputs the target evaporator temperature Teo in the normal mode and does not perform the cold storage instruction or the cool-down instruction. The process ends.
Here, the first threshold value is determined based on the relationship between the accelerator depression amount and the acceleration feeling. For example, the first threshold value can be set to 20% of the maximum depression amount. The second threshold can be set to 0.5, for example. However, when emphasizing cold storage, the second threshold value may be set to a value lower than 0.5. Conversely, when the driving feeling is important, the second threshold value can be set to a value higher than 0.5.

  On the other hand, if the output determination unit 534 determines in step 502 that the accelerator depression amount 36a is larger than the first threshold value, the process proceeds to step 505. Thereafter, when the regenerator temperature Tc is equal to or lower than the limit regenerator temperature Tco, the output determination unit 534 outputs the cool-out instruction signal and the previously read target evaporator temperature information Teo (= Tco, for example, 12 ° C.) (506). . In Step 505, when the regenerator temperature Tc is higher than the limit regenerator temperature Tco, the process is terminated.

  Next, FIGS. 10A to 10D are explanatory diagrams showing an operation example by the driving action intention estimation means 52 and the determination means 53.

  FIG. 10A shows the engine output that changes according to the road gradient when the driver assumes that the driver keeps the current speed from the current t0 and proceeds on the road, and particularly requires a large engine output at a steep slope. It shows that. The engine output is estimated based on road gradient information received by a car navigation system, for example.

  10 (b) to 10 (d) show that the regenerator 40 cools a little during the time t0 to t1 before the time t1 when the large engine output is required due to the steep slope, and is released from the time t1. Indicates to cool.

  Therefore, the determination unit 53 outputs a cold storage instruction signal from the current time t0 to the time point t1 (FIG. 10B). Moreover, the determination means 53 outputs a cool-down instruction | indication signal only from the time t1 until the temperature of the cool storage device 40 becomes the limit cool storage device temperature Tco (FIG.10 (c)). In addition, when a cold storage instruction is generated from the current time t0, the determination unit 53 can gradually store the target evaporator temperature Teo1 in accordance with the engine output state and the air conditioning state in order to achieve both driving feeling and comfort in the passenger compartment. The minimum temperature (Min) is set to 1 ° C.

  As described above, according to the present embodiment, the vehicle air conditioner uses the target evaporator temperature Teo determined by the air conditioning environment condition in the normal mode shown in FIG. That is, since the necessity for cooling and dehumidification is reduced in the intermediate temperature range (for example, 18 to 25 ° C.) of the outside air temperature Tam, the target evaporator temperature Teo is increased (for example, 12 ° C.) and the operation rate of the compressor 1 is increased. By reducing the power, the power saving of the engine 4 can be achieved.

  Moreover, the vehicle air conditioner sets the target evaporator temperature Teo to the target evaporator temperature Teo1 (for example, 1 to 8 ° C.) required for the cold storage of the cool storage unit 40 in the cold storage mode shown in FIG. In the present embodiment, as shown in FIGS. 8 and 9, the vehicle air conditioner sets the cold storage mode from the time when it is estimated that the braking action is performed in addition to the braking time during which the vehicle is actually braked. In addition, the vehicle air conditioner makes the driver feel uncomfortable only during the time from when the output increase is estimated until the output increase action is taken even when the engine output increases during acceleration action or climbing action. Set to cold storage mode to store cold to the extent that it does not. By performing such setting, it is possible to set the cool storage mode time for performing cool storage longer than the actual braking time, and it is possible to increase the cool storage amount.

  In the cooling mode shown in FIG. 3, for example, when idling is stopped, even if the compressor 1 is stopped during the period until the regenerator temperature Tc of the regenerator 40 reaches the limit regenerator temperature Tco, the regenerator 40 It becomes possible to maintain air conditioning for a relatively long time by using the cold storage capacity. In addition, as the cooling mode, there are acceleration, climbing, and engine output increase in a broad sense. At this time, the compressor 1 (refrigeration cycle) is stopped, which is necessary without hindering acceleration and climbing operation feeling. It becomes possible to provide air conditioning.

  Moreover, according to the present embodiment, as shown in FIGS. 8 and 9, the similarity of the driving pattern by the driving action intention estimation unit 52 and the certainty of the braking action or the acceleration action by the determination unit 53 are used. Thus, it is possible to estimate the latest braking action or acceleration action of the driver at a point earlier than the actual braking action or acceleration action of the driver and with a higher probability. Therefore, it is possible to ensure a long cool storage time more reliably.

  Furthermore, according to this embodiment, as shown in FIG. 8, the vehicle air conditioner determines the target evaporator temperature Teo1 when entering the cold storage mode based on the output template preset and stored in the output template storage unit 533. It is set according to the engine output state. Therefore, the engine output can be prevented from changing suddenly even when the cold storage mode is entered at the time of the latest braking action estimation, the actual braking action, or the latest acceleration action estimation.

(Other embodiments)
According to the said embodiment, although the application example to the vehicle air conditioner which controls the air conditioner 100 provided with the cool storage device 40 is demonstrated, this invention is set as the structure which cools and cools to the cool storage device 40. It is not limited. The present invention estimates the driver's intention of driving behavior (for example, acceleration or braking) and estimates the output state of the power source of the vehicle at an early stage, and provides the air conditioning control means with the air conditioning capability corresponding to the output state. The adjustment instruction is made so that the driving feeling and the comfort in the passenger compartment are compatible.

  For example, the compressor load of the air conditioner may be temporarily reduced by estimating the intention of the driving action early even when the engine load becomes large, such as when merging on an expressway. The present invention can also be applied to a vehicle using a motor as a power source, such as a hybrid vehicle or an electric vehicle combining an engine and a motor. For example, when the load state of the power source becomes large, the intention of the driver's driving behavior is estimated and the output state of the power source of the vehicle is estimated early. And the influence from the electric compressor (electric load) with respect to a vehicle-mounted power supply is reduced by adjusting to the operation state (air-conditioning capability) of the electric compressor of the air conditioner according to the estimated output state. Therefore, it is possible to prevent the power supply voltage from being lowered due to the overload of the power supply and to prevent the driving feeling from deteriorating.

In addition, according to the present embodiment, the driving behavior of the driver is described by dividing it into braking behavior and acceleration behavior, but the acceleration behavior in this example includes acceleration behavior and climbing behavior, and in a broad sense, engine output It means driving behavior at the time of increase.
Further, according to the present embodiment, the driving pattern template storage unit 523 in the driving action intention estimation unit 52 stores driving pattern templates for each type of detection information obtained in advance through experiments or the like, as shown in FIGS. Is configured to do. The driving pattern template storage unit 523 stores and sets a standard driving pattern template common to many drivers. On the other hand, since individual drivers have personal habits and characteristics when driving, it is even more personal to learn those habits and characteristics from actual driving patterns and reflect them in the driving pattern template. Adaptation is possible, and it becomes possible to improve the determination accuracy of the driving pattern.

  Therefore, in the embodiment shown in FIG. 11, as a learning process step, an actual driving pattern (driving behavior data) detection process for the control flow in FIG. 5 and a driving pattern template correction for the driving pattern template storage unit 523 are performed. Processing (steps 205 and 206) is added.

  First, step 205 is a learning condition determination step for determining whether or not to perform a learning process. In this example, when the degree of similarity is high, the detection accuracy of the driving pattern is improved by capturing various detection information. Accordingly, when the driving action intention estimation means 52 determines that the similarity calculated in step 204 is a braking action or an acceleration action with a predetermined value or more, the driving action intention estimating unit 52 proceeds to step 206, and sampling data (driving data) for each type of detection information at that time. Action data) and is temporarily stored in the RAM or storage means 51.

Subsequently, in step 206, every time braking action data or acceleration action data is accumulated a predetermined number of times, the driving action intention estimation means 52 obtains a braking action pattern or acceleration action pattern obtained by averaging them. The driving action intention estimation means 52 corrects each template of the braking driving pattern and the acceleration driving pattern stored in the driving pattern template storage unit 523 using the obtained braking action pattern or acceleration action pattern, and performs individual driving. To reflect the driving patterns unique to the driver. In addition, it is preferable that the correction of each template is, for example, a weighted average process, and the data amount of each template that is initially set and stored is gradually corrected so that the determination accuracy is stable.
On the other hand, if it is determined in step 205 that the degree of similarity is lower than the predetermined value, the learning process is not performed and the process ends.

Note that in the learning condition determination step of step 205, it is possible to determine whether or not to perform learning using a certainty factor instead of a similarity factor. In this case, the driving action intention estimation means 52 reads the certainty factor calculated by the certainty factor calculation unit 531 in the procedure shown in FIG. Then, the driving action intention estimation unit 52 compares the certainty factor with a predetermined value. If the certainty factor is greater than or equal to the predetermined value, the process proceeds to step 206 to perform learning processing.
Here, when the similarity is used to determine whether or not to perform learning, the predetermined value is set to 0.7, for example. On the other hand, when the certainty factor is used to determine whether or not to perform learning, the predetermined value is set to 0.5, for example. Note that the predetermined values are not limited to these values, and if it is desired to modify each template more carefully, these threshold values may be set higher. Conversely, if it is desired to correct each template more actively, these threshold values may be set lower.
