Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention provides a LAN (local area network) by connecting an air conditioner amplifier unit (master station) and one or more door actuators (slave stations) via one communication line and one power line. ) And belongs to the technical field of an amplifier reception processing device of a vehicle air conditioner system that controls the opening degrees of a plurality of doors.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as an air conditioner system for a vehicle, for example, as described in Japanese Patent Application Laid-Open No. 6-8746, an actuator drive circuit for driving each door actuator is incorporated in an air conditioner amplifier unit for air mix doors and mode doors. In addition, there is known a device in which each actuator for an intake door and a drive circuit are connected by a harness.
[0003]
[Problems to be solved by the invention]
However, in the above-mentioned conventional vehicle air conditioner system, the drive circuit and each door actuator are connected by five to nine harnesses, respectively, and the number and weight of the harnesses become large. Door actuators are of different types, such as a potentiometer type and an encoder type, so that mass production effects cannot be expected. Further, incorporating an actuator drive circuit in an air conditioner amplifier unit increases the size of the amplifier and the load on the microcomputer.
[0004]
Therefore, a solution to these problems is a LAN that connects the air-conditioner amplifier unit and a plurality of door actuators with one communication line.
[0005]
That is, by adopting the LAN, the number of harnesses can be reduced, the actuators can be integrated, and the amplifier can be downsized. As a result, excellent advantages such as reduced system weight and reduced system cost can be obtained.
[0006]
However, even if an attempt is made to adopt a LAN system instead of the current system, the following problems must be solved.
[0007]
In the current system, each door actuator is driven by a drive command signal from the actuator drive circuit of the air conditioner amplifier unit, and a feedback signal of the operating position is returned from the door actuator to the air conditioner amplifier unit in real time. By checking the corresponding feedback signal, it can be determined in real time whether the door is opening and closing normally.
[0008]
However, when the LAN is adopted, if the door target stop position data of each door is unilaterally transmitted to the door actuator in accordance with a predetermined rotation, the door operation cannot be checked.
[0009]
Therefore, a reply signal is added to the communication data from the door actuator to the air conditioner amplifier unit. When the indication value for changing the door target stop position data is changed, the reply signal in the frame in which the changed indication value was transmitted. Is a signal indicating the stop before the change of the indicated value, and is not a signal indicating the operation, but is a signal indicating the operation only by a reply signal in the frame when the next indicated value is transmitted.
[0010]
That is, the communication data including the reply signal is sequentially transmitted according to a predetermined rotation. Therefore, when the data indication value is changed, the actuator starts operating after the change of the indication value, and the actuator starts after the actuator operation starts. A reply signal indicating the operation is issued. In particular, an air conditioning system having a larger number of door actuators has a longer delay time.
[0011]
Therefore, when data for changing the instruction value of the door opening is transmitted from the air conditioner amplifier unit to the door actuator, a certain period of time (50 msec to 100 msec for one door actuator) is required until a response signal indicating operation is returned from the door actuator. In short, during that time, the state becomes indefinite, and abnormal operation (hunting in the 8.5V regulation control of the fan) occurs.
[0012]
SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicular air-conditioning system that drives and controls a plurality of door actuators. It is an object of the present invention to provide an amplifier reception processing device for preventing an abnormal operation due to a delay of the amplifier.

[0023]

[0030]
FIG. 3 is a diagram showing a network between an amplifier / actuator. As shown in FIG. 3, the air conditioner amplifier unit 25 and each door actuator 21, 22, 23, 24 have one communication line 36 and one power supply.

[0031]
FIG. 4 is a diagram showing a physical layer (a layer having a function of establishing, maintaining, and canceling the electrical connection of a line in a network) omitting a protection circuit between an amplifier and an actuator. Are represented by two types of pulse amplitudes H / L using a ternary code that superimposes the pulse amplitudes. The ASIC of the actuator extracts a clock from the communication signal, and the logic circuit of the ASIC performs decoding of the communication signal (operation for restoring encoded data) and other operations based on the extracted clock. Since the clock signal is supplied only from the amplifier, the communication speed can be arbitrarily set by software of the amplifier.
[0032]
FIG. 5A is a transmission timing chart showing the transmission operation of the amplifier. When the CLK output (clock output) is H, the communication line 36 is grounded by Tr1 regardless of the DATA output (data output).

A signal set by RXDATA and reset at the rising edge of RXCLK is sampled at the falling edge of RXCLK to perform decoding. NRZ in the figure is the extracted data.
[0034]
Next, the operation will be described.
[0035]
[Communication procedure]
The communication procedure will be described with reference to FIGS.
[0036]
The signal used for communication defines H / L by two kinds of pulse amplitudes as shown in the communication waveform of FIG. Then, as shown in the encoding table of FIG. 6B, 2-bit binary data is represented by a combination of three pulses.
[0037]
As shown in FIG. 7, the communication format is SOM (Start Of Message) indicating the start of transmission, ADR (address) indicating the address of the actuator to be transmitted, ENA (enable) indicating permission or prohibition of motor drive, and door. (DATA) indicating the target stop position, PRTY (odd parity) for checking ADR, ENA, and DATA errors, and POS (control end signal) indicating a diagnostic actuator return signal. FIG. 8 shows an example of the communication format. The hatched portion is always an H pulse.
[0038]
Describing the reception sequence, the ASIC starts the reception sequence by receiving the SOM indicating the beginning of the communication format. The ASIC fetches the following data only when the corresponding address is detected, but terminates the reception sequence and discards the received data when detecting a combination or a parity error with a waveform that is not in the encoding table. When the SOM is received during the reception sequence, the reception sequence starts over from the beginning. The ASIC drives the motor only when the enable is 1, and when the enable is 0, only updates the data and does not drive the motor.
[0039]
Explaining the response from the actuator, the amplifier always turns off Tr2 in the POS signal portion, and the two pulses representing the POS signal are usually both H pulses. The actuator that has received the signal from the amplifier turns on Tr3 at a timing such that the second pulse of the POS signal becomes an L pulse if the door position has reached the target position and control has been completed. The amplifier can determine whether or not the door of the actuator to be transmitted is at the target position by monitoring the amplitude of the POS signal. The reply from the actuator is made only when the normal reception is completed, but not when the address does not match or an error occurs. FIG. 9A shows the POS signal under control, and FIG. 9B shows the POS signal at the end of control.
[0040]
[Air mix door actuator operation management processing operation]
FIG. 10 is a flowchart showing the flow of the operation of the air mix door actuator operation management process performed by the air conditioner amplifier unit 25.
[0041]
In steps 50 to 52, it is determined whether or not the temperature deviation S between the set temperature and the actual temperature exceeds an allowable deviation of -1 ≦ S ≦ 1, and in steps 53 to 57, a flag corresponding to the temperature deviation S is determined. Processing such as set and flag reset is performed, and in steps 58 to 63, the virtual door opening XPBR that increases or decreases from 100% of full hot to 0% of full cool is determined.
[0042]
The active flag is reset in step 64 when the command is to increase the virtual door opening XPBR, and the active flag is set in step 65 when the command is to decrease the virtual door opening XPBR. When the command value is changed after one of steps 64 and 65, the process proceeds to step 66, in which the 25-second timer is cleared in step 66, the 25-second timer start flag is reset in step 67, and in step 68, the ENA drives the motor. In step 69, the POS flag is forcibly set to Hi indicating operation (corresponding to the first amplifier reception processing means in claim 1).
[0043]
When the temperature deviation S is an allowable deviation or when the return signal POS is forcibly set in step 69, the process proceeds to step 70, where it is determined whether the return signal POS is Lo. When the POS is Lo, the process proceeds from Step 70 to Step 64 → Step 71, and when the POS is Hi, the process proceeds from Step 70 to Step 72 → Step 73. In Step 73, it is determined whether the time is 25 seconds or more. If it is shorter than seconds, the process proceeds to step 68 → step 71, and if it is longer than 25 seconds, the process proceeds to step 64 → step 74 → step 75. In step 71, it is determined whether or not the system operation is permitted. If the system operation is permitted, the process returns to step 50. If the system operation is not permitted, the process proceeds to step 75 and returns to step 50.
[0044]
[Mode door actuator operation management processing operation]
FIG. 11 is a flowchart showing the flow of the mode door actuator operation management processing operation performed by the air conditioner amplifier unit 25.
[0045]
In step 76, the previous virtual door opening XMDPBR is set as XMDPBR '. In steps 77 to 81, it is determined which of the target modes (VENT is vent, B / L is bilevel, and D / F is differential foot). In steps 82 to 87, the virtual door opening XMDPBR is set according to the target mode.
[0046]
Then, in step 88, it is determined whether or not the current virtual door opening XMDPBR set in any of steps 82 to 87 is the same as the previous virtual door opening XMDPBR '. If the virtual door opening is different between the previous time and the current time, the process proceeds to step 89, where the magnitude relation is compared. Unless the virtual door is in the locked state, the process goes through step 90, step 91, step 92, step 56, step 57 and step 93 to step 93. Proceed to. In the locked state, the process proceeds from step 57 to step 75.
[0047]
In step 93, the same processing as in steps 66 and 67 is performed. After step 65, in step 69, the POS flag is forcibly set to Hi indicating operation. Then, a one-second timer is set in step 94, and the process proceeds to step 68 and subsequent steps.
[0048]
On the other hand, if it is determined in step 88 that XMDPBR = XMDPBR ', then it is determined in step 95 whether or not one second has elapsed. If not, the process proceeds to step 72 and proceeds to step 70. The routine for confirming the return signal POS in step (1) is ignored, and the process of forcibly setting Hi in step 69 is maintained (corresponding to the first amplifier reception processing means in claim 2).
[0049]
The processing after step 70 is the same as in FIG.
[0050]
[Actuator communication processing operation]
FIG. 12 is a flowchart showing the flow of the actuator communication processing operation performed by the air conditioner amplifier unit 25. The routine enclosed by the dotted line in FIG. It is a routine showing a receiving process.
[0051]
Further, after the transmission processing and the reception processing in FIG. 12, the actuator communication data processing (MKACTRDT) is performed. This actuator communication data processing is performed according to the flowchart shown in FIG.
[0052]
[Amplifier reception processing operation]
The amplifier reception process in the door actuator operation management process performed by the air conditioner amplifier unit 25 is performed according to the flowchart shown in FIG. 10. In particular, when the command value is changed after one of steps 64 and 65, the POS flag is set at step 69. Is forcibly rewritten to Hi indicating the operation.
[0053]
That is, when data for changing the instruction value of the door opening is transmitted from the air conditioner amplifier unit 25 to the air-mix door actuator 23, a delay until the Hi-mix signal POS indicating the actual operation is returned from the air-mix door actuator 23 is returned. During the time, provisional control is performed under the condition setting that the actuator is in operation by forcibly rewriting the POS flag. When the return signal POS is returned, the return signal memory is set to stop or in operation. And lead to normal operation.
[0054]
Therefore, when the data for changing the instruction value of the door opening is transmitted from the air conditioner amplifier unit 25 to the air mix door actuator 23, the state is indefinite until the return signal POS indicating the operation is sent back from the air mix door actuator 23. For example, in order to secure the door operation torque of the air mix door 15, the fan control for restricting the maximum voltage value to the fan motor 5 to 8.5V when the air mix door actuator 23 is operating. When the air mix door actuator 23 is actually operating, the 8.5V regulation is started due to the fact that the regulation is not regulated to 8.5 V or the indication value is changed, but immediately after that, the actuator operation is confirmed. Prevents control hunting that would result in regulation being released Rukoto can.
[0055]
In the operation management process of the mode door actuator 24 performed by the air conditioner amplifier unit 25, the process of receiving the amplifier from the mode door actuator 24 is performed according to the flowchart shown in FIG. When the value is changed, the POS flag is forcibly rewritten to Hi indicating the operation in step 69, and a one-second timer is set in step 94. Then, even if it is determined in step 88 that the command value has not been changed, if it is determined in step 95 that one second or more has not elapsed, the routine proceeds to step 72, and the routine for checking the return signal POS in step 70 is performed. The process of ignoring and forcibly setting Hi in step 69 is maintained.
[0056]
That is, after the forced rewriting to the operation signal Hi, the routine for checking the return signal POS for a set time of 1 second is ignored even if the change of the indicated value is stopped, and the rewriting process to Hi is maintained. During this time, when the rewriting control to Hi is maintained, when data for changing the instruction value of the door opening is transmitted from the air conditioner amplifier unit 25 to the mode door actuator 24, a reply indicating the operation from the mode door actuator 24 is sent. Until the signal POS is sent back, the state does not become indefinite, and abnormal operation such as fan control can be prevented in the same manner as described above.
[0057]
Next, effects will be described.
[0058]
(1) The air conditioner amplifier unit 25 and the plurality of door actuators 21, 22, 23, 24 are connected via one communication line 36 and one power supply line 37, and each door actuator 21, The door target stop position data DATA and the like are sequentially transmitted to 22, 23, and 24 via one communication line 36, and a reply signal POS indicating the operation or stop of each door actuator 21, 22, 23, or 24 is transmitted to the transmission data. And the amplifier reception processing program for forcibly rewriting the POS flag to a flag indicating the operation when the instruction value for changing the door target stop position data DATA is set is set in the air conditioner amplifier unit 25. LAN to reduce system weight and system cost, It is possible to provide an amplifier receiving apparatus to prevent abnormal operation due to return signal POS delay during 示値 change.
[0059]
(2) In the air conditioner amplifier unit 25, when the instruction value for changing the door target stop position data DATA is changed, the POS flag is forcibly rewritten to a flag indicating operation, and after the forcible POS flag is rewritten, the instruction value is changed. Since the routine to check the return signal for 1 second is ignored even if the error has disappeared and the amplifier reception processing program that maintains the rewriting process has been set, the door actuator side Even if an abnormal reply signal POS is output, control based on Hi indicating operation is maintained, and abnormal operation can be reliably prevented.
[0060]
(Other embodiments)
In the first embodiment, an example in which four door actuators 21, 22, 23, and 24 are provided has been described. However, the present invention can be applied to a system in which a plurality of door actuators other than four are provided. Of course.
[0061]
In the first embodiment, the example in which the method of the amplifier reception processing according to the first and second aspects of the present invention is applied to the mixed door actuator 23 and the mode-a actuator 24 has been described. However, it may be applied to other door actuators.
[0062]
In addition to the amplifier reception processing described in the first embodiment, as described in claim 3, a routine for checking the return signal for the set time when changing the instruction value for changing the door target stop position data is ignored. Then, a second amplifier reception processing means for maintaining the previous processing may be provided. In this case, Lo is maintained if Lo in the previous processing, and Hi is maintained if Hi in the previous processing to prevent the state from becoming indefinite until at least the return signal POS returns. Can be.
[0063]

Response signal delay when changing the indicated value while reducing system and system costs Effect that the abnormal operation due capable of providing an amplifier receiving apparatus to prevent.
[0064]
According to a second aspect of the present invention, in the amplifier reception processing device of the vehicle air conditioner system according to the first aspect, the first amplifier reception processing means changes the indicated value after rewriting the operation signal to a forced operation signal. Since the routine for checking the return signal for the set time is ignored even if the error has disappeared and the rewriting process is maintained, in addition to the above effects, abnormal Even if a reply signal is issued, abnormal operation can be reliably prevented.
