Abstract

PROBLEM TO BE SOLVED: To prevent a vehicle occupant who may touch the interior member of the vehicle from feeling uncomfortable owing to a great temperature difference between the occupant's body and the member by performing control for eliminating the temperature difference to have conditioned air blowing to a predetermined position expected to be touched by the occupant of the vehicle upon starting air conditioning by a remote starting signal. SOLUTION: When activating an air conditioning unit for vehicle in response to the engine starting signal by a remote control engine starter, if the vehicle has been unoccupied and the inside temperature thereof has not been kept at the normal state, control for blowing air to a steering 81 is performed. When the blower air flow rate is maximized at recirculation mode and the blower mode is set at bi-level or face mode, the blower air temperature limit is reset. The louver is directed toward the steering 81 and then to swing around the area where the air blow on the steering wheel 81. After finishing the control for blowing air, the control may be shifted to another phase for blowing air to a seat back 82 for a while. This makes it possible to prevent a driver 80 from feeling uncomfortable because of the reduced temperature difference between the driver's body and the portion of the vehicle interior member in contact therewith.

The present invention relates to a vehicle air conditioner.

[0002]

2. Description of the Related Art A technique for remotely starting an air conditioner together with an engine using a remote control engine starter is known. Also, if you get on the vehicle and touch the steering wheel or sit in the seat, you may feel hot or cold depending on the season. To alleviate this problem, there is known a technology for cooling or heating the steering by flowing conditioned air through the hollow portion of the steering wheel (Japanese Utility Model Application Laid-Open No. 56-1342).
No. 71). By combining both technologies, a vehicle air conditioner can be obtained that cools or heats the steering when the air conditioner is remotely started together with the engine to eliminate discomfort when riding.

[0003]

However, a precise mechanism is required to realize a technique for flowing air-conditioning air through the hollow portion of the steering wheel, so that the manufacturing cost increases and is not practical. An object of the present invention is to provide an inexpensive configuration when a vehicle air conditioner is started by a remote controller and the user gets in the vehicle, so that even if the body touches the vehicle interior member, the temperature difference between the two members is small so that discomfort does not occur. It is an object of the present invention to provide a vehicle air conditioner that can be used.

A temperature difference elimination control is performed in which one or both of the restriction is released and the degree of air conditioning of the conditioned air blown into the vehicle interior is increased. As a result, the amount of air-conditioned air increases or the degree of air-conditioning increases, and the location where the air-conditioned air hits is quickly heated or cooled.
When the passenger gets into the vehicle, the temperature difference between the point and the body is small and no discomfort occurs.

[Claim 6] The duct has a foot outlet for blowing conditioned air to the feet of the occupant, a defroster outlet for blowing conditioned air to the inner surface of the windshield, and a center face blower for blowing conditioned air toward the occupant's face. It has an outlet and opening and closing means for opening and closing each outlet. When the air-conditioning operation is started by the remote start signal, the following is performed.

As a result, the conditioned air is blown out from the center face in a concentrated manner, or is blown out from the center face outlet and the foot outlet, so that the area hit by the conditioned air is efficiently heated or cooled, so that the passenger enters the vehicle. In this case, the temperature difference between the place and the body is small, and no discomfort occurs.

[Claim 7] The duct has a passenger side face air outlet that blows conditioned air toward the occupant of the passenger seat, and a driver side face air outlet that blows conditioned air toward the occupant of the driver seat. Further, a plurality of opening / closing means for opening / closing these face outlets are provided. When the air-conditioning operation is started by the remote start signal, the following is performed. A plurality of dampers are controlled so that the passenger side face outlet is closed and the driver side face outlet is opened so that the conditioned air is blown out only from the driver side face outlet. This method is effective when the part that blows out the conditioned air is a steering wheel or a backrest. A plurality of dampers are controlled so that both face outlets are opened such that conditioned air is blown out from both face outlets. When blowing conditioned air to two parts,
This method may be used when conditioned air is blown out from both face outlets to the same site.

[0011] [Claim 8] When the vehicle air conditioner is started by remote control operation, if the occupant is on board (including the case where the occupant is on board from the beginning), the vehicle door is opened and closed. Or an operation signal indicating that any of the operating devices in the passenger compartment has been operated, or a seating signal indicating that the occupant is sitting in the seat is input to the control means. Is done. Further, when the temperature in the vehicle compartment falls within a predetermined range or when a predetermined time elapses from the input of the remote start signal, the heating and cooling of different parts such as the steering wheel and the backrest are completed. In such a case, the control for blowing out the conditioned air to different parts is ended.

First, the data processing memory is initialized (step s100). Subsequently, the set temperature (driver side and passenger side) set by the temperature setting switch of the air conditioner operation panel and each sensor signal are read and stored in the data processing memory (step s11).
0). Next, the read data and the following formula,
And the target outlet temperature TAO (D
r) and the target outlet temperature TAO (Pa) on the passenger side
Is calculated (step s120).

[0032]

TAO (Dr) = Kset · Tset (Dr) −Kr · Tr−Kam−Ks · Ts + Kd (Dr) · {Cd (Dr) + Ka (Dr) · (10−Tam)} × ｛Tset (Dr) ) −Tset (Pa)｝ + C …………………………….

Note that Ka (D

Subsequently, when the foot mode or the foot / diff mode is selected by the manual operation on the air conditioner operation panel 60 at step s140, the operation pattern of the louver 5 disposed on each side face outlet 152, 181 is selected. Is calculated (step s150). When the foot mode and the foot / diff mode are selected, the mode switching doors 153, 183 close the center face outlets 151, 182 and open the side face outlets 152, 181.
Blowing air is also blown from 52 and 181.

After determining the operation pattern of the louver 5 in step s150, the target blowing temperature TAO on the driver side is determined.

SW (Dr) = {TAO (Dr) -TE)} × 100 / (TW-TE)

SW (Pa) = {TAO (Pa) −TE)} × 100 / (TW−TE) Then, the control voltage VA obtained in step s130 is applied to the blower 11 (fan motor). Thus, the control signal is output to the motor drive circuit 61 (step s170).
Subsequently, the target opening degree SW (D
r) and actuators 411, 4 for driving the air mix doors 41, 42 so as to obtain SW (Pa).
The control signal is output to the control signal 21 (step s180). Subsequently, a control signal is output to each of the actuators 154 and 173 so as to obtain the driver-side outlet mode and the passenger-side outlet mode determined in step s140 (step s190). In step s200, a control signal is output to each of the stepping motors 711 and 721 so that the operation pattern of the louver 5 calculated in step s150 is obtained.

On the other hand, when the vehicle air conditioner 1 is operated by an engine start signal (the air conditioner is turned on) by the remote control engine starter, the control program of steps s1 to s11 shown in FIG. 10 is executed.

In step s1, it is determined whether or not the temperature in the vehicle compartment is in a steady state (more than 10 ° C. and less than 30 ° C.). If it is determined that it is not in the steady state (NO in step s1), the process proceeds to step s2.

At step s2, it is determined whether or not a door opening / closing signal has been input (the door has been opened and the vehicle has been entered). If not (NO), control for blowing out to the steering 81 (steps s3 to s8) ). However,
Since there is a possibility that the driver 80 operates the remote control engine starter from inside the vehicle, it is desirable to adopt a configuration in which the following determination is made. If a seat belt wearing signal or a seating signal is detected, it is determined that the vehicle has already been taken, and the process proceeds to normal control (step s100). If any of the operation switches in the vehicle compartment is operated, it is determined that the vehicle is already in the vehicle, and the process proceeds to the normal control (step s100).

The blower air volume is maximized (step s3),
The inside / outside air switching is performed in the inside air mode (step s4), the blowing mode is B / L or FACE mode (step s5), and the blowing temperature limit is released (step s6). Step s7
Then, control for turning the louver 5 in the direction of the steering 81 and swinging the blown wind in a range where the louver 5 hits the steering 81 is started (see FIG. 11). At this time, each face outlet 1
81, 182 (passenger side grill) steering 81
Preferably it is oriented or closed. Steps
At 8, the engine speed is increased. Steps s3-s
The controls in steps 6 and s8 are for effectively changing the steering temperature by blowing the conditioned air to the steering 81.

If the temperature of the cooling water is lower than 60 ° C. (NO in step s9), the time until the elapse of 5 minutes after the air conditioner is turned on (NO in step s10), or the temperature in the vehicle compartment is lower than 10 ° C. or higher than 30 ° C. (In step s11, N
In step O), the flow returns to step s2 to continue the blowing control to the steering 81.

When the blowing control to the steering 81 is completed (YE in steps s9, s10 and s11)
In S), the control may not be immediately shifted to the normal control (step s100), but may be shifted to the control of blowing out to the seat back 82 for a while (see FIG. 12). If the outside air temperature is equal to or lower than a predetermined value, the mode may be switched to the DEF mode.

Next, advantages of this embodiment will be described. [A] When the air-conditioning operation is started by operating the engine with the remote control, the ECU 6 controls the louver 5 so that the conditioned air is blown out to the steering 81 and the backrest 82. Thus, the steering 81 and the backrest 82 are heated or cooled by the conditioned air, and even if the driver 80 gets into the vehicle and touches the body of the steering wheel 81 and the backrest 82, the temperature difference between the two is small and no discomfort occurs.

[A] When the air-conditioning operation is started with the engine operated by the remote controller, the ECU 6 maximizes the blower air volume (step s3), the inside air mode (step s4), and the blow mode is the B / L or FACE mode (step s3). s5), the blow-out temperature limit is released (step s6), and the louver 5 is directed toward the steering 81 so that the blow-off wind is turned to the steering 8
The swing is performed in the range corresponding to 1 (step s7), and the engine speed is increased (step s8). Thus, the temperature of the steering 81 and the backrest 82 can be efficiently raised or lowered in a short time.

[C] During warm-up control (step s)
3 to s8), the control returns to the normal control when the cooling water temperature rises to 60 ° C. or higher, the vehicle compartment temperature rises to 10 ° C. to 30 ° C., or when 5 minutes have elapsed since the A / C was turned on. Therefore, unnecessary consumption of energy can be prevented, and deterioration of the steering 81 and the backrest 82 due to the warm-up control can be prevented. In addition, the vehicle interior can be evenly air-conditioned.

The present invention includes the following embodiments in addition to the above embodiments. FIG. 13 and FIG.
In the case of the concentrated diffusion louver 500 shown in FIG. 14, the wind direction change to the steering or the backrest is performed on the concentrated blowing side (FIG. 14).
