Description
Technical Field
The present invention relates to a method for adjusting an air conditioning system as a function of vehicle speed and an air conditioning system. The invention also relates to a vehicle and a computer readable storage medium.
Background
In vehicles, there are different systems which should support the driver in such a way that the driver feels comfortable while driving. One of these systems is an air conditioning device for achieving a comfortable interior room temperature for the driver and occupants. In this case, various adjustment possibilities exist, depending on the specific embodiment of the air conditioning system. For example, embodiments are possible in which the driver and the secondary drive can individually manually adjust the temperature desired for themselves, for example by means of a knob.
A method for regulating an air conditioning system is known from EP1116611A1, in which the temperature of the interior of the vehicle is automatically regulated as a function of the time of day. It is further proposed to regulate the temperature of the interior according to the detected driver behavior.
Disclosure of Invention
Since there is always a need for improvement in the conditioning of air conditioning systems in vehicles, it is an object of the present invention to provide a corresponding method and system which provides improved conditioning of the air conditioning of the vehicle interior.
A method for controlling an air conditioning system of a vehicle is proposed, wherein at least the temperature of the interior region in which the driver is located is automatically controlled from a preset temperature start value to a speed-dependent temperature value or to a reduced or increased predetermined value as a function of the current speed of the vehicle, wherein the speed-dependent temperature value is calculated as follows:
where F (v) is a function related to speed, C is a preset temperature start value in degrees Celsius, and v is the current speed in km/h.
By automatically adapting the temperature of the interior area in which the driver is located, on the one hand, a temperature that is always comfortable for the driver can be adjusted, and on the other hand, a manual temperature adaptation by the driver can be avoided, which is advantageous in particular at higher speeds.
In addition, the temperature is set to decrease with increasing speed. Advantageously, the temperature is continuously reduced. With a higher concentration at higher speeds, the driver heats up faster. By automatically adapting the temperature, it is prevented that the driver needs to make manual adjustments.
In addition, the speed-dependent temperature value is set to be at most 3 ℃ below the preset temperature starting value. It is thus possible to prevent the driver from feeling cold and thus make manual adjustments.
In addition, the temperature is set not to exceed a preset temperature starting value. It is thus prevented that the temperature preset for the driver and regarded as the ideal temperature is exceeded, becomes overheated for the driver, and the driver then makes a manual adjustment.
In addition, it is set that the temperature is regulated for the first time when the speed exceeds a threshold value of 80-120 km/h. In addition, it is provided that the temperature is again adjusted to a preset value when the speed is below a predetermined threshold value.
When the low range has not been reached or the high range has been exceeded, the temperature adaptation may be disadvantageous for the driver to concentrate on, because the driver initially feels cold or becomes overheated for the driver. This may lead to disturbances in the concentration.
An air conditioning system for a vehicle is also proposed, which comprises an adjusting device, which is designed to adjust at least the interior region of the vehicle, in which the driver is located, to a predetermined temperature, the adjusting device of the air conditioning system being coupled to an adjusting device of a speed regulator of the vehicle, such that the adjusting device of the air conditioning system obtains a current driving speed of the vehicle. The control device of the air conditioning system is further configured such that the control device of the air conditioning system automatically adjusts the temperature of at least the interior space region in which the driver is located from a preset temperature start value to a speed-dependent temperature value or to a reduced or increased predetermined value as a function of the current speed of the vehicle, wherein the speed-dependent temperature value to be adjusted is calculated as follows:
where F (v) is a function related to speed, C is a preset temperature start value in degrees Celsius, and v is the current speed in km/h.
A vehicle having the air conditioning apparatus is also provided.
There is also provided a computer readable storage medium having stored thereon instructions which, when executed by a processor, cause the processor to perform the method of the present invention.
Other features and advantages of the invention will be apparent from the following description of embodiments of the invention, taken in conjunction with the accompanying drawings, which illustrate, by way of example, details of the invention. The individual features can be implemented in the variant of the invention individually or in any combination of a plurality of them.
Drawings
Preferred embodiments of the present invention will be explained in detail below with reference to the accompanying drawings.
Fig. 1 shows a schematic diagram of the essential components of an embodiment of the invention for carrying out the method in a vehicle.
FIG. 2 shows a graph depicting the relationship between temperature and speed in accordance with one embodiment of the present invention.
Detailed Description
The method and system described below are described with reference to use in a vehicle, for example a car or a van, having a corresponding installation, which vehicle comprises at least one air conditioning system with an air conditioning regulator. In the following, the air conditioner is examined only in the front region of the vehicle, more precisely to a conditioner which adjusts the temperature that is comfortable for the driver in different driving situations and reduces the necessity for manual adjustment.
An air conditioning system is a system that maintains a uniform temperature in the vehicle interior and a comfort level for the occupants. For this purpose, a combination of a vehicle heating and cooling system with an associated control system is used. The temperature that is comfortable for the occupant in the front region can generally be adjusted here via a control region that is arranged between the driver and the driver. The temperature is then automatically adjusted such that the temperature remains unchanged during driving.
It is known that the human body has an increased temperature with an increase in concentration. This may also occur, for example, on the driver when the driver increases the driving speed. There may be cases where: the driver perceives the preset temperature as too high and manually reduces the temperature. For this purpose, the driver needs to take one hand off the steering wheel and operate the operating element, which is usually out of the driver's line of sight if the driver looks at the lane.
It is therefore proposed that the air conditioning system 1, in particular the control device of the air conditioning system 1, be connected or coupled to a speed regulator 10 of the vehicle, as shown in fig. 1. In this case, a temperature of at least the interior region of the vehicle 100 in which the driver is located is set as a function of the current speed v. The current speed v is provided by the speed regulator 10.
At or before the start of the drive, there is a temperature start value C, which generally reflects a temperature that is comfortable for the driver. The temperature value is either adjusted by the driver during or after boarding, or a preset value of the vehicle is used. The value that has been stored in advance for a particular driver may also be automatically adjusted if the driver has been identified.
As the speed of the vehicle 100 increases, the driver is also necessarily more focused, causing the temperature of the driver to increase. This may become uncomfortable for the driver from the determined limit value, so that the driver wants to manually lower the temperature in order to re-feel comfort. To avoid this, the air conditioning apparatus 1 is coupled with a speed regulator 10 of the vehicle. When the vehicle 100 exceeds a predetermined threshold value of speed, for example 100km/h in fig. 2, at least the temperature of the interior space region in which the driver is located is reduced by a predetermined value, preferably a calculated value, or a predetermined low temperature value is set.
For the adaptation, for example, a range may be specified, within which the adaptation may be performed, for example, within a range of 80 to 120km/h or 100 to 200km/h, as shown in fig. 2. In this case, when a speed threshold of, for example, 80km/h, 100km/h or 120km/h is reached, the temperature start value is adapted as specified in order to set the temperature. Such a rule is set, for example, by a function, formula (1) described below. The threshold is selected such that the threshold is greater than a speed at which the driver wants to make a manual change in temperature. This may be determined by general field tests, scientific tests, etc. and employed for the vehicle. A speed threshold value, which can be determined specifically, can also be determined for each driver, from which a temperature adjustment is to be carried out.
The temperature is adjusted as follows: the current temperature of the interior compartment area in which the driver is located is adjusted in relation to the current speed of the vehicle. As the speed increases, the temperature decreases. But the degree of decrease is only at most a predetermined value, for example at most 3 deg.c, so that the smallest automatically adjustable temperature is in this embodiment the temperature start value C minus 3 deg.c. The maximum reduction value may be either preset by the manufacturer or the driver may change the value within the adjustment range. If the maximum value of the range is exceeded, no further reduction of the temperature takes place.
The same applies for the range minima. When the range minimum is lowered, the temperature is not increased any further beyond the predetermined starting value C. Since the air conditioning system 1 or its control device 10 obtains the current speed value by means of a mutual coupling, for example by interrogation or notification, an automatic temperature regulation to a new setpoint value is possible.
This is described below in equation (1) and shown in fig. 2.
The function F (v) describes the entire course of the change. The velocity v is measured in km/h in equation (1). The temperature start value C is measured in degrees celsius in equation (1). Of course, other ranges or other units of measure may be employed depending on the implementation.
In the example shown in equation (1) and in fig. 2, the starting temperature C is now adjusted, for example, to 20 ℃, and the temperature is automatically adjusted to the new nominal value of 18.5 ℃ when accelerating to 150 km/h.
As long as the current speed is within the range of 100km/h to 200km/h, the temperature is correspondingly adjusted, see formula (1).
When the driver now again reduces the speed to a speed below 100km/h, the temperature again increases to the starting temperature C and remains there, i.e. does not continue to increase.
The decrease or increase in temperature may be performed stepwise or continuously. The predetermined values of speed and temperature may be adjusted differently depending on the driver. For example, women have a different thermal sensation and a different tension sensation than men. This situation can be considered as follows: the function F (v) is selected in accordance with preset driver characteristics.
In principle, not only the control device of the air conditioning system 1 but also the speed controller 10 can be present in a single control unit, with reference numeral 10 being provided in fig. 1.
