Description

[0001] The present disclosure relates to a motor vehicle and a method for controlling operation of the motor vehicle. Additionally or alternatively, a computer program is provided comprising instructions that, when executed by a computer, cause the computer to perform the method. Additionally or alternatively, a computer-readable medium is provided comprising instructions that, when executed by a computer, cause the computer to perform the method.

[0002] A so-called rain-light-solar-fogging sensor (RLSBS) is known from the prior art, which is mounted in a mirror base of a rear-view mirror of a motor vehicle.

[0003] This RLSBS can be used to detect or record solar intensity or the position of the sun for the front area of a vehicle's passenger compartment. In other words, the RLSBS is currently only suitable for detecting the area of a driver and front passenger, as the solar sensor does not have a field of view for the rear of the vehicle.

[0004] However, this is challenging when a 4-zone automatic climate control or a 4-zone air conditioning system is to be controlled based on the sun identity and the sun angle detected by the sensor, since no values are available for the two rear zones.

[0005] It would be conceivable to attach an additional sensor to the vehicle, for example, to a (glass) roof of the vehicle, positioned in such a way that the solar radiation angle and intensity can also be recorded for the rear area of the passenger compartment. However, this would require an additional sensor, which should be avoided.

[0006] Furthermore, reference is also made to DE 10 2019 121 055 A1, which relates to a method, a device, and a vehicle for determining an interior temperature of the vehicle. The method comprises the steps of: determining a starting value for the interior temperature of the vehicle based on a temperature sensor of a control unit of the vehicle, wherein the control unit comprises a housing, and the temperature sensor is provided for detecting heat development of components within the housing of the control unit; determining a current interior temperature of the vehicle based on the starting value and on the basis of a temperature model for the interior temperature; and using information about the determined interior temperature in the vehicle, in particular for controlling an air conditioning control unit of the vehicle.

[0007] DE 103 26 649 A1 describes a multi-zone air conditioning system with a plurality of individual climate zones, in particular for motor vehicles, with a control device for controlling climate parameters determining the interior climate, such as room temperature, mixed air composition, air distribution and / or fan speed, according to predetermined control characteristics as a function of environmental parameters detected by sensors, such as solar radiation, wherein an individual, climate-zone-specific air nozzle arrangement, consisting of at least one air nozzle, is provided for each individual climate zone.

[0008] DE 195 26 450 C1 describes a method for controlling an air conditioning system for a vehicle interior, which has several air conditioning ducts for different interior zones, wherein the individual air conditioning ducts are controlled depending on the seat occupancy.

[0009] DE 10 2017 207 533 A1 describes a method for energy-efficient temperature control in a motor vehicle, comprising detecting at least one temperature input into the motor vehicle, determining at least one movable component within the motor vehicle which is affected by the detected temperature input, and moving the at least one movable component into a position in which the temperature input is varied.

[0010] DE 197 04 415 A1 describes a sensor device for an automatic driving light switch of a vehicle, in which a collecting optic is arranged upstream of a light receiving element, wherein an optical element is arranged upstream of the collecting optic, the light entry surface of which, facing away from the collecting optic, is inclined in the vertical direction relative to the vehicle's longitudinal axis and the optical axis in such a way that a front light beam incident approximately parallel to the vehicle's longitudinal axis is refracted in such a way that it runs approximately parallel to the optical axis of the collecting optic and is focused by the collecting optic onto the light receiving element.

[0011] Against the background of this prior art, the object of the present disclosure is to provide a device and / or a method which are each suitable for enriching the prior art.

[0012] A specific embodiment of the disclosure can solve the problem of determining a solar radiation angle and / or a (solar) intensity for a rear area of a passenger compartment of the motor vehicle by means of only a single (solar) sensor installed in the area of the windscreen or windshield of the motor vehicle.

[0013] The problem is solved by the features of the independent claims. The subclaims each contain optional developments of the disclosure.

[0014] According to this, the object is achieved by a motor vehicle, wherein the motor vehicle comprises a windscreen and a sensor which is arranged on the windscreen and is designed to detect a solar radiation angle and / or an intensity for solar radiation for a front area (inside) the passenger compartment of the motor vehicle.

[0015] The motor vehicle comprises a control device connected to the sensor, which is designed to determine a solar radiation angle and / or an intensity of solar radiation for a rear area (inside) the passenger compartment of the motor vehicle based on the solar radiation angle detected by the sensor and / or the intensity of solar radiation for the front area of the passenger compartment detected by the sensor, map data comprising information about a position of the sun as a function of a time of day, and information about a current position of the motor vehicle and a current time of day.

[0016] This means that it is proposed to use means already present in the motor vehicle to determine the solar radiation, i.e. an angle of solar radiation and / or an intensity of solar radiation, also for the rear area of the passenger compartment or the interior of the motor vehicle.

[0017] For this purpose, an RLSBS described above is used, for example. This system includes a solar sensor that detects or records the solar radiation angle and intensity for the front area of the passenger compartment, typically for the driver and front passenger. The information recorded by the sensor is used by the control unit, along with map information and information about the current position or location, as well as the current time at that location, to determine or calculate the solar radiation angle and / or intensity for the rear area of the passenger compartment.

[0018] This offers, among other things, the advantage that an additional or separate sensor for detecting the angle of sunlight and / or the intensity of sunlight for the rear area of the passenger compartment can be omitted.

[0019] The motor vehicle may be a passenger car, such as an automobile, and / or a commercial vehicle.

[0020] Insofar as a front and a rear region of the passenger compartment of the motor vehicle is mentioned, a front region can be understood as an area in which a first row of seats is arranged. The rear region can be understood as a second region of the passenger compartment arranged behind the front region in the longitudinal direction of the motor vehicle and comprising a further or second row of seats. The present disclosure is not limited to motor vehicles with two rows of seats, but can also be applied to motor vehicles with more than two rows of seats, such as an additional row of seats behind the second row of seats. These multiple rear rows of seats then together represent the rear region.

[0021] The control device can, for example, be an electronic control unit (ECU). The electronic control unit can be an intelligent processor-controlled unit that can communicate with other modules, for example, via a central gateway (CGW), and that can, if necessary, form the vehicle's on-board network via fieldbuses such as the CAN bus, the LIN bus, the MOS bus, FlexRay, and / or via Automotive Ethernet, for example with telematics control units and / or environmental sensors.

[0022] The motor vehicle includes a dimmable exterior window arranged in the passenger compartment area. The control device is configured to control dimming of the exterior window based on the solar radiation angle detected for the front area of the passenger compartment and determined for the rear area of the passenger compartment and / or the solar radiation intensity detected for the front area of the passenger compartment and determined for the rear area of the passenger compartment.

[0023] Optional further developments of the motor vehicle described above are explained in detail below.

[0024] The motor vehicle may include a rearview mirror attached to the windshield via a mirror base. It is conceivable that the sensor is arranged at least partially in the mirror base.

[0025] In other words, the sensor may be part of the rearview mirror and positioned to face the front of the motor vehicle.

[0026] The motor vehicle may include an air conditioning system or an air conditioning unit for air conditioning the passenger compartment. The control device may be configured to control the air conditioning system based on the solar radiation angle detected for the front area of the passenger compartment and determined for the rear area of the passenger compartment and / or the solar radiation intensity detected for the front area of the passenger compartment and determined for the rear area of the passenger compartment.

[0027] In other words, the control device can be designed to automatically control the air conditioning system of the motor vehicle based on the values detected by the sensor as described above, as well as the map data and the information about the current time and the current location of the motor vehicle.

[0028] The air conditioning system can be designed as a 2-zone air conditioning system, which is configured so that the air conditioning of the front and rear areas of the passenger compartment can be controlled separately.

[0029] In other words, the front area of the motor vehicle can correspond to a first zone, and the rear area of the motor vehicle can correspond to a second zone. These two zones can be air-conditioned independently of each other using the dual-zone air conditioning system, meaning that the temperature in these two zones, or in the front and rear areas of the passenger compartment, can be adjusted independently or separately.

[0030] The control device may be configured to control the air conditioning of the front area of the passenger compartment based on the detected solar radiation angle and / or the detected solar radiation intensity for the front area of the passenger compartment.

[0031] This means that the temperature in the front area or the first zone can be controlled by means of the control device based on the values relevant for the front area of the passenger compartment.

[0032] The control device may be configured to control the air conditioning of the rear area of the passenger compartment based on the determined solar radiation angle or the determined solar radiation intensity for the rear area of the passenger compartment.

[0033] This means that, analogous to the front area, the rear area of the passenger compartment or the second zone can also be automated based on the values relevant to this area and, if necessary, controlled separately from the front area.

[0034] The air conditioning system can also be designed as a 4-zone air conditioning system, which is configured so that the air conditioning of a front left and a front right as well as a rear left and a rear right area of the passenger compartment can be controlled separately.

[0035] In the present disclosure, the terms left and right refer to a vehicle width direction. That is, the left area generally corresponds to a driver's side, whereas the right area generally corresponds to a passenger side (reverse for right-hand drive vehicles).

[0036] The sensor may be configured to separately detect the angle of solar radiation and / or the intensity of solar radiation for the front left and front right areas of the passenger compartment of the motor vehicle.

[0037] This means that the sensor can be designed to detect both the angle of solar radiation and the intensity of solar radiation for the driver's side and the passenger side separately in the front area of the passenger compartment.

[0038] The control device can be configured to separately determine the solar radiation angle and / or the intensity of the solar radiation for the rear right and rear left areas of the passenger compartment of the motor vehicle based on the solar radiation angles and / or the intensities of the solar radiation for the front left and right areas of the passenger compartment detected by the sensor, the map data comprising information about the position of the sun as a function of the time, and the information about the current position of the motor vehicle and the current time.

[0039] The control device may be configured to control the air conditioning of the front left area of the passenger compartment based on the detected solar radiation angle and / or the detected solar radiation intensity for the front left area of the passenger compartment.

[0040] The air conditioning of the front right area of the passenger compartment can be controlled by the control device based on the detected solar radiation angle and / or the detected solar radiation intensity for the front right area of the passenger compartment.

[0041] The air conditioning of the rear left area of the passenger compartment can be controlled by the control device based on the determined solar radiation angle and / or the determined solar radiation intensity for the rear left area of the passenger compartment.

[0042] The air conditioning of the rear right area of the passenger compartment can be controlled based on the determined solar radiation angle and / or the determined solar radiation intensity for the rear right area of the passenger compartment.

[0043] In other words, according to the present disclosure, it is also possible for a 4-zone automatic climate control system to be controlled automatically by the control device for all four zones.

[0044] It is conceivable that the dimmable exterior window is a glass roof of the vehicle.

[0045] The above can be summarized in other words and in a more concrete form of the disclosure as described below, whereby the following summary is not to be construed as limiting the disclosure.

[0046] The sun's intensity or position is currently detected by the RLSBS at the front of the car. This is mounted on the windshield. However, the current principle only allows detection in the area of the driver and front passenger, as the solar sensor has no field of view of the rear of the vehicle.

[0047] The aim now is to avoid buttons in the interior and a separate solar sensor in the roof, whereby the 4-zone air conditioning and shading of the windows are to be controlled automatically, and a 360° solar function in the vehicle is to be provided by the already installed RLSBS.

[0048] The RLSBS already installed in the vehicle is intended to detect the position and intensity of the sun for the entire vehicle. This eliminates the need for an additional sensor and additional buttons in the vehicle interior.

[0049] Using map data from the vehicle, which provides information about sun and shadow, and the additional GPS information (date, time, location) in combination with the solar intensity measured by the sensor, the solar radiation intensity at the rear of the vehicle can also be recorded or determined.

[0050] This information can be used to control the four-zone automatic climate control system with just one sensor instead of two. Furthermore, the information can be used, additionally or alternatively, to control the dimming of the vehicle's glass roof. This is particularly advantageous if a sunblind is not required.

[0051] Furthermore, the present disclosure relates to a method for controlling an operation of a motor vehicle.

[0052] The motor vehicle comprises a windscreen, a sensor arranged on the windscreen and configured to detect an angle of solar radiation and / or an intensity of solar radiation for a front region of a passenger compartment of the motor vehicle, and a control device connected to the sensor.

[0053] The method comprises detecting the angle of solar radiation and / or the intensity of solar radiation for the front area of the passenger compartment by means of the sensor.

[0054] The method further comprises determining a solar radiation angle and / or an intensity of solar radiation for a rear region of the passenger compartment of the motor vehicle by means of the control device based on the solar radiation angle and / or the intensity of solar radiation for the front region of the passenger compartment detected by the sensor, map data comprising information about a position of the sun as a function of a time of day, and information about a current position of the motor vehicle and a current time of day.

[0055] Furthermore, it is provided that the motor vehicle comprises a dimmable exterior window arranged in the area of the passenger compartment, and the control device controls dimming of the exterior window based on the angle of solar radiation detected for the front area of the passenger compartment and determined for the rear area of the passenger compartment and / or the intensity of solar radiation detected for the front area of the passenger compartment and determined for the rear area of the passenger compartment.

[0056] The method may be a computer-implemented method. This means that one, several, or all steps of the method can be carried out at least partially by a computer or a data processing device.

[0057] What has been described above with reference to the motor vehicle also applies analogously to the procedure and vice versa.

[0058] Furthermore, a computer program is provided, comprising instructions which, when executed by a computer, cause the computer to at least partially carry out or perform the method described above.

[0059] A program code of the computer program may be in any code, in particular in a code that is suitable for controlling motor vehicles.

[0060] What has been described above with reference to the control device, the motor vehicle and the method also applies analogously to the computer program and vice versa.

[0061] Furthermore, a computer-readable medium, in particular a computer-readable storage medium, is provided. The computer-readable medium comprises instructions which, when executed by a computer, cause the computer to at least partially execute or perform the method described above.

[0062] This means that a computer-readable medium can be provided that contains a computer program as defined above. The computer-readable medium can be any digital data storage device, such as a USB flash drive, a hard disk, a CD-ROM, an SD card, and / or an SSD card (or SSD drive / SSD hard disk).

[0063] The computer program does not necessarily have to be stored on such a computer-readable storage medium in order to be made available to the motor vehicle, but can also be obtained via the Internet or otherwise externally.

[0064] What has been described above with reference to the motor vehicle, the method and the computer program also applies analogously to the computer-readable medium and vice versa.

[0065] Below is an optional embodiment with reference to Fig. 1 - 3 described. Fig. 1 shows schematically a motor vehicle in a side view, Fig. 2 shows schematically a motor vehicle in a plan view and Fig. 3 schematically shows a flow diagram of a method for controlling an operation of the Fig. 1 and Fig. 2 of the motor vehicle shown.

[0066] The Fig. 1 and Fig. 2, the motor vehicle 1 shown only schematically comprises a windscreen 2, a sensor 3 arranged on the windscreen 2, a control device 6 connected to the sensor 3, and an air conditioning system 9 which is also connected to the control device 6.

[0067] Therefore, the motor vehicle 1 is equipped to carry out the following with reference to Fig. 2 (control) procedures described in detail.

[0068] In a first step S1 of the method, the angle of solar radiation and / or the intensity of the solar radiation for the front area 4 of the passenger compartment 8 is detected by means of the sensor 3.

[0069] Sensor 3 in this case can be, for example, a solar sensor. This can be part of a rain-light-solar-fog sensor.

[0070] In a second step S2 of the method, a solar radiation angle and / or an intensity of solar radiation for the rear area 5 of the passenger compartment 8 of the motor vehicle 1 is determined by means of the control device 6. For this purpose, the control device 6 uses the solar radiation angle detected by the sensor 3 and / or the intensity of solar radiation for the front area 4 of the passenger compartment 8 detected by the sensor 3, map data which comprise information about a position of the sun as a function of a time, and information about a current position of the motor vehicle 1 and a current time.

[0071] In a third step S3 of the method, operation of the air conditioning system 9 is controlled by means of the control device 6. The operation of the air conditioning system 9 is controlled based on the angle of solar radiation detected for the front area 4 of the passenger compartment 8 and determined for the rear area 5 of the passenger compartment 8 and / or the intensity of solar radiation detected for the front area 4 of the passenger compartment 8 and determined for the rear area 5 of the passenger compartment 8.

[0072] The control of the air conditioning system 9 depends on a design of the air conditioning system 9. It is conceivable that the air conditioning system 9 is designed as a 2-zone air conditioning system, which is configured such that the air conditioning of the front and rear areas 4, 5 of the passenger compartment 8 can be controlled separately from one another. The control device 6 can then, in the third step S3, control the air conditioning of the front area 4 of the passenger compartment 8 based on the detected solar radiation angle and / or the detected solar radiation intensity for the front area 4 of the passenger compartment 8. The air conditioning of the rear area 5 of the passenger compartment 8 can be controlled analogously based on the determined solar radiation angle and / or the determined solar radiation intensity for the rear area 5 of the passenger compartment 8.

[0073] However, it is also conceivable that the air conditioning system is designed as a 4-zone air conditioning system, which is configured such that the air conditioning of a front left and a front right as well as a rear left and a rear right area 41, 42, 51, 52 of the passenger compartment 8 can be controlled separately from one another.

[0074] The sensor 3 can then be designed such that in the first step S1 of the method it separately detects the angle of solar radiation and / or the intensity of the solar radiation for both the front left and the front right areas 41, 42 of the passenger compartment 8 of the motor vehicle 1.

[0075] In the second step S2 of the method, the control device 6 can then separately determine the solar radiation angle and / or the intensity of the solar radiation for the rear right and rear left areas 51, 52 of the passenger compartment 8 of the motor vehicle 1 in the manner described above based on the solar radiation angles detected by the sensor for the front left and front right areas 41, 42 and / or the intensities of the solar radiation for the front left and right areas 41, 42 of the passenger compartment 8 detected by the sensor, the map data which include information about the position of the sun as a function of the time and the information about the current position of the motor vehicle 1 and the current time.

[0076] In the third step S3 of the method, the operation of the air conditioning system 9 is subsequently controlled as described in detail below. The air conditioning of the front left area 41 of the passenger compartment 8 is carried out based on the detected solar radiation angle and / or the detected solar radiation intensity for the front left area 41 of the passenger compartment 8. The air conditioning of the front right area 42 of the passenger compartment 8 is carried out based on the detected solar radiation angle and / or the detected solar radiation intensity for the front right area 42 of the passenger compartment 8.

[0077] The air conditioning of the rear left area 51 of the passenger compartment 8 is carried out based on the determined solar radiation angle and / or the determined solar radiation intensity for the rear left area 51 of the passenger compartment 8. Similarly, the air conditioning of the rear right area 52 of the passenger compartment 8 is carried out based on the determined solar radiation angle and / or the determined solar radiation intensity for the rear right area 52 of the passenger compartment 8.

[0078] In a fourth step S4 (not shown) of the method, which can run parallel or simultaneously to the third step S3 of the method, a dimming of a dimmable exterior window 7 is controlled. The dimmable exterior window 7 of the motor vehicle 1 is in this case a glass roof of the motor vehicle 1. This glass roof or exterior window 7 is arranged in an area of the passenger compartment 8, more precisely above the passenger compartment 8. The control device 6 controls the dimming of the exterior window 7 based on the angle of incidence of the sun detected for the front area 4 of the passenger compartment 8 and determined for the rear area 5 of the passenger compartment 8 and / or the intensity of the solar radiation detected for the front area 4 of the passenger compartment 8 and determined for the rear area 5 of the passenger compartment 8.

[0079] The description for the 2-zone air conditioning system and the 4-zone air conditioning system, which was explained in detail above, applies analogously to the dimming of the exterior window 7. This means that it is conceivable that the dimming of the exterior window 7 can also be carried out zone-by-zone or in different zones assigned to the respective zones or areas 4, 5, 41, 42, 51, 52 of the passenger compartment 8, depending on the values applicable to these zones or areas 4, 5, 41, 42, 51, 52, i.e., the angle of solar radiation and / or the intensity of the solar radiation.
