Description
-1- PCT/EP00/02140 04.04.2001 Mannesmann VDO AG 4184 PCT Description Device for controlling the passenger compartment temperature of a motor vehicle The invention relates to a device for controlling the passenger compartment temperature of a motor vehicle, in which the passenger compartment temperature is measured by means of a passenger compartment temperature sensor and in a passenger compartment temperature control device is compared with a passenger compartment temperature set-point, and the output signal from the passenger compartment temperature control device is first fed to a blown air outlet temperature control device, which controls a cooling/heating device for the blown air to be delivered to the passenger compartment, the outlet temperature of the blown air being measured by at least two blown air outlet temperature sensors, which are arranged in blown air ducts terminating at different points in the passenger compartment, the output signal from the passenger compartment temperature control device being compared in the blown air outlet temperature control device with the value measured by a blown air outlet temperature sensor and the output signal at the same time being fed to an air distribution control element arranged in each of the blown air ducts for adjustment of the passenger compartment temperature, and the measuring signals from the blown air outlet temperature sensors being fed to a blown air outlet temperature control device, which weights the measured values independently of one another. DE 197 08 383 C1 discloses a device of this type, in which the weighted measured superimposed values then undergo further processing.
2 Vehicle air-conditioning systems have a climate cont-rol device, which generates the blown air- to be delivered to the passenger compartment of the vehicle to be climate-controlled. Such a climate control device has a cooling unit and a heating unit, a fan and blown air ducts leading into the passenger compartment. The individual components of the climate control device are controlled and the distribution of blown air outlet is directed to the various blown air ducts by means of control elements.
If only one blown air outlet sensor is arranged in an air outlet duct, the measurement cannot be utilized if there is no air coming out of the blown air duct.
DE 43 36 934 C2 discloses a method of controlling the passenger compartment temperature, to which a blown air outlet temperature control is subordinated in order to control the blown air outlet temperature within a predeterminable temperature range, two blown air outlet temperature sensors being used. In order to enhance passenger comfort yet further, the output signals both of the passenger compartment temperature control device and of the blown air sensors are linked to one another in complicated combinations of multiple closed-loop and openloop control circuits.
25 The object of the invention is to propose a device for reliable passenger compartment temperature control with subordinated blown air outlet temperature control, which functions simply and reliably but nevertheless ensures a high level of passenger comfort in the vehicle passenger compartment.
According to the invention there is provided a device for controlling the passenger compartment temperature of a motor vehicle, in which the passenger compartment temperature is measured by means of a passenger ee. 35 compartment temperature sensor and is compared in a "".passenger compartment temperature control device with a passenger compartment temperature set-point, \\melbfiles\homeS\Priynka\eep\speci\ 3 42 Ssoo Amendments.doc 2/06/03 2a and an output signal from the passenger compartment temperature control device is fed to a blown air- outlet temperature control device, which controls a cooling/heating device for the blown air to be delivered to the passenger compartment, the blown air outlet temperature of the blown air being measured by at least two blown air outlet temperature sensors, which are arranged in blown air ducts terminating at different points in the passenger compartment, and the output signal from the passenger compartment temperature control device being compared in the blown air outlet temperature control device with the value measured by the blown air outlet temperature sensors, and the output signal from the passenger compartment temperature control device being fed to an air distribution control element arranged in each of the blown air ducts for adjustment of the passenger compartment temperature, and the measuring signals from the blown air outlet temperature sensors being fed to a blown air outlet temperature control device which weights the measured values independently of one another, wherein only the measured value from that blown air 25 outlet temperature sensor with a greatest flow of air around it is compared with the output signal from the •ale passenger compartment temperature control device.
The advantage of an embodiment of the invention resides in the fact that despite such a simple evaluation, a reliable climate control is achieved. Since the temperature sensors can measure correctly only if air flows around them, the measured value of the sensor having the greatest flow of air around it is given the highest weighting..
eo• o o o °o \\melb-files\hoeS\Priyank\Keep\speci\34 2 88-00 Amendens.doc 2/06/03 4184 PCT 3 The air distribution control element is advantageously connected to the blown air outlet temperature control device, the individual measured values of the blown air outlet temperature sensors being weighted as a function of the position of the blown air outlet control element that controls the blown air outlet flow in the outlet duct, in which an assigned sensor is arranged. From the air distribution to the individual blown air ducts it is known what proportion of the blown air is flowing out by way of the blown air duct assigned to the blown air outlet temperature sensor. Reliable weighting is therefore possible.
The invention permits numerous possible embodiments. One of these will be explained in more detail with reference to the figures shown in the drawing, in which: Figure 1: shows an air-conditioning unit of a motor vehicle, Figure 2: shows the passenger compartment temperature control of the motor vehicle.
Identical features are identified by the same reference numbers.
Figure 1 represents the air-conditioning unit 1 in its actual arrangement in the motor vehicle 2.
Fresh air is drawn into the motor vehicle 2 from the surroundings of the motor vehicle by way of the fresh air flap 3, the position of which is controlled by a servomotor 4 as a function of electrical output signals from the air conditioning control module The circulating air from the passenger compartment of the motor vehicle is drawn in by the air conditioning unit 1 by way of the circulating air flap 6. The position of the circulating air flap 6 is also controlled by a servomotor 7 as a function of electrical signals from the air conditioning control module 5. The fan 8 delivers circulating and fresh air 4184 PCT -4 into the air conditioning unit i, thereby producing mixed air 9 downstream of the fan 8.
This said mixed air 9 is delivered to the evaporator In cooling mode the mixed air 9 is delivered to the passenger compartment 14 by way of outlet ducts 11, 12, 13. These said outlet ducts 11, 12,13 point toward the windscreen, toward the driver and front passenger respectively and toward the foot area of the driver and the front passenger. The air inlet can be adjusted automatically by servomotors, not shown further, or manually by the driver and/or front passenger, by means of the air distributor flaps 15, 16, 17 arranged in the individual ducts 11, 12, 13.
A heat exchanger 18 is connected to the evaporator The air flow delivered by the evaporator 10 is ducted past the heat exchanger 18 by means of a temperature flap 19, being heated up in the process.
In the heating mode the correspondingly warmed mixed dair 9 then flows into the passenger compartment 14.
The air conditioning control module 5 is generally arranged in or in proximity to the dashboard of the vehicle 1, so that when underway it can easily be operated by the driver and front passenger.
The microprocessor arranged in the air conditioning control module 5 controls the interior temperature in the passenger compartment 14, as shown in figure 2.
By means of the operating controls 20, arranged on the air-conditioning control module 5, the driver or front passenger enters the desired passenger compartment temperature as set-point value for the passenger compartment temperature control 21. The latter compares the actual interior temperature, which is measured by means of the passenger compartment temperature sensor 22. The flaps 15, 16, 17 are actuated as a function of this comparison, thereby 4184 PCT 5 adjusting the interior temperature in the passenger compartment 14.
In a subordinated control the output signal from the passenger compartment temperature control device 21 is fed to a blown air outlet temperature control device 23 for heating the air to the desired temperature.
This actuates the heat exchanger 18 and the temperature flap 19 for heating or the fresh air flap 3 and the fan 8 for cooling as a function of the blown air outlet temperatures measured by a blown air outlet temperature sensor 24, 25, 26 arranged in each of the individual blown air outlet ducts 11, 12, 13 respectively.
The measuring results separately provided by the blown air outlet temperature sensors 24, 25, 26 are weighted in a blown air outlet temperature control device 27.
The measuring results are weighted as a function of the position of the flaps 15, 16, 17 arranged in the individual outlet ducts 11, 12, 13. At the same time the blown air outlet sensor arranged in the outlet duct correlates with the flap also arranged in the same duct.
The weighting for each air distributor flap 16, 17 is performed as follows: if the air distributor flap 15, 16, 17 is closed, that is to say there is no flow of air around the assigned blown air outlet temperature sensor 24, 25, 26, its measured values are not taken into account in the blown air outlet temperature control 23.
If it is determined that the air distributor flap 16, 17 is fully opened, it is assumed that there is a full flow of air around the blown air outlet temperature sensor 24, 25, 26 situated in the corresponding air outlet duct 11, 12, 13 and the measured value supplied by the blown air outlet temperature sensor 24, 25, 26 is taken fully into account.
6 If the air distributor flap 15, 16, 17 is only open, the value of the associated blown air outlet temperature sensor 24, 25, 26 in this air distributor flap 16, 17 is also only 40% weighted.
After weighting, the measured value of the blown air outlet temperature sensor 24, 25, 26 with the greatest air flow around it is further processed.
The use of three blown air outlet temperature sensors 24, 25, 26 ensures that a value representative of the temperature of the blown air is at all times used for adjustment of the blown air outlet temperature control 23.
