Description

[0001] The invention relates to a method for supporting optimized temperature control of the interior of a vehicle with automatically opening and closing vehicle openings.

[0002] From DE 41 30 226 C1, a method for air conditioning the interior of a vehicle is known. The vehicle has at least one part that can be opened by means of a drive motor, an interior temperature setpoint transmitter, at least one interior temperature sensor, at least one outside temperature sensor, a logic module with inputs and outputs, and a computer module. Existing components from various systems are used and linked in such a way that the driver is largely relieved of operating tasks.

[0003] Furthermore, DE 41 05 143 C1 describes an interior air conditioning device for a vehicle. In this device, a vehicle blower from the vehicle's own ventilation system, an openable and closable vehicle opening (such as a roof or window), and a motor-independent heater are linked via an operating control circuit to form a functional unit. When a predetermined upper temperature limit is exceeded, one of the actuators for the openable and closable vehicle opening is controlled and activated. When a predetermined lower temperature limit is not reached, the motor-independent heater is controlled and put into operation.

[0004] US patent 11 577 688 B2 describes intelligent window devices for use in vehicles. Such a device includes a control circuit that collects data from a parked vehicle, uses this data to determine a vehicle status indicating a relatively high interior temperature or an unattended occupant, and opens a vehicle window via a window regulator to cool the vehicle interior.

[0005] DE 10 2005 033 404 A1 discloses a method for preventing overheating of a vehicle interior, whereby the interior temperature of the vehicle interior and the presence of living beings are detected. If the driver's seat is unoccupied, the interior temperature is lowered when a temperature limit is exceeded.

[0006] US patent 2006 0179 853 A1 discloses a passenger protection system with a carbon dioxide sensor and a temperature sensor. The sensors are electrically connected to a control unit and generate a temperature signal indicating the temperature inside the vehicle. The control unit is configured to initiate a safety action based on the carbon dioxide and temperature signals.

[0007] The invention is based on the objective of providing a method for supporting optimized air conditioning of a vehicle's interior.

[0008] The problem is solved according to the invention by a method which has the features specified in claim 1.

[0009] Advantageous embodiments of the invention are the subject of the dependent claims.

[0010] According to the invention, a method for supporting optimized temperature control of a vehicle interior with automatically opening and closing vehicle openings provides that, when it is determined that an interior temperature detected by the vehicle exceeds a predetermined threshold and a difference between an interior temperature and an outside temperature detected by the vehicle exceeds a further predetermined threshold, a visual and / or acoustic recommendation is issued to the vehicle user to automatically open all vehicle openings by actuating a control element. At least after a certain temperature value is reached, all opened vehicle openings are closed again by actuating the control element.

[0011] By applying this method, the vehicle user is advised to ventilate the interior, especially when the interior temperature is comparatively high.

[0012] By means of a single actuation of the control element, which is displayed, for example, on a touch-sensitive display unit and is carried out after confirmation, all vehicle openings, in particular vehicle windows and, if applicable, a vehicle roof, can be opened and closed automatically and simultaneously.

[0013] Once the process is implemented in a vehicle, so-called CO2 credits for such functionality can be applied for, e.g., at a registration authority.

[0014] If the vehicle is an electric vehicle, the electric range of the vehicle designed as an electric vehicle can be increased by applying the method, in particular by first opening the vehicle windows and not exclusively activating an air conditioning device of the vehicle to temperature the interior.

[0015] Exemplary embodiments of the invention are explained in more detail below with reference to drawings.

[0016] This shows: Fig. 1. Schematic top view of a vehicle with components for carrying out a method to support optimized temperature control of a vehicle interior with automatically opening and closing vehicle openings. Fig. 2 schematically a section of the vehicle's instrument panel and a steering wheel and Fig. 3 schematically illustrates a process flow to support the optimized temperature control of the vehicle's interior.

[0017] Corresponding parts are marked with the same reference symbols in all figures.

[0018] Fig. Figure 1 shows a top view of a vehicle 1 with components for carrying out a method to support optimized temperature control of an interior of the vehicle 1 with automatically opening and closing vehicle openings F, in particular window openings 1.1 and a roof opening 1.2.

[0019] In Fig. Figure 2 shows a section of an instrument panel 1.3 of the vehicle 1 and a steering wheel 1.4, wherein in Fig. Figure 3 shows a procedure for optimizing the temperature control of the interior of vehicle 1.

[0020] It is generally known that it is possible to apply for so-called CO2 credits or CO2 certificates from a registration authority through comparatively special measures and / or procedures in the normal driving operation of a vehicle 1.

[0021] For example, a vehicle 1 which has a specific cooler capable of initiating air-improving measures during the operation of vehicle 1 can obtain such a CO2 certificate.

[0022] Furthermore, it is known that a vehicle 1, and especially its interior, can heat up considerably due to solar radiation. For example, a white vehicle 1 can receive a CO2 certificate compared to a black vehicle 1, which heats up more.

[0023] If, after entering a heated vehicle 1, an air conditioning device of the vehicle 1 (not shown in detail) is activated to raise the interior temperature T I Reducing the energy consumption during driving operation typically affects the overall energy consumption of vehicle 1.

[0024] In particular, opening the vehicle openings F during the first part of the journey can increase the interior temperature T. I through natural airflow and by switching on a ventilation system in the vehicle 1, approximately to an outside temperature T A The temperature can be reduced. Subsequent activation of the air conditioning system can lower the interior temperature T. I then lowered further. In comparison, the interior temperature T I If the energy consumption can be reduced solely by activating the air conditioning device, the overall energy consumption of vehicle 1 will then be lower.

[0025] To maintain the interior temperature T I To optimize and reduce the energy consumption of vehicle 1, particularly after heating by solar radiation, taking into account the total energy consumption of vehicle 1, the procedure described below is provided.

[0026] As described above, vehicle 1 has a number of components required to carry out the procedure. These components include an interior temperature sensor 1.5, an exterior temperature sensor 1.6, an evaluation unit 1.7 connected to the interior temperature sensor 1.5 and the exterior temperature sensor 1.6 for analyzing the recorded temperature values, a fan motor 1.8, a display unit 1.9, and a control element 1.10.

[0027] The in Fig. The procedure shown in Figure 3 begins with Start S, where decisions are represented by a j (yes) and a n (no).

[0028] In a first process step S1, the evaluation unit 1.7 is used to determine whether an indoor temperature T determined on the basis of signals recorded by the indoor temperature sensor 1.5 is correct. IThe procedure proceeds to the start S if the vehicle 1 exceeds a predefined threshold SW1. If this is not the case, the procedure jumps to the start S.

[0029] If the evaluation unit 1.7 is used in the first process step S1 to determine that the determined indoor temperature T I If the specified threshold SW1 is exceeded, then in a second process step S2 it is checked whether there is a difference between the determined indoor temperature T I and an outside temperature T determined on the basis of signals recorded by the outside temperature sensor 1.6 A is greater than a specified further threshold SW2.

[0030] If this is not the case, the procedure jumps to start S. However, if it is determined that the difference between the temperatures T I , T AIf the threshold SW2 is greater than the further threshold value, the procedure proceeds to a third process step S3. The third process step S3 involves displaying a request or recommendation in a display area of ​​the display unit 1.9, in particular an infotainment system of the vehicle 1. The request or recommendation asks whether all vehicle openings F, i.e., the window openings 1.1 and the roof opening 1.2, should be opened. If the request is answered with "No" in a fourth process step S4, the procedure proceeds to the start S. If the request is confirmed or the recommendation is accepted, whereby a vehicle user activates a single control element 1.10 located on the steering wheel 1.4, all vehicle openings F that are to be opened automatically, i.e., the window openings 1.1 and the roof opening 1.2, are opened automatically and simultaneously in a fifth process step S5.

[0031] Alternatively or additionally, the request or recommendation can also be issued acoustically, with confirmation via a voice command, after which all vehicle openings F are automatically opened.

[0032] In a sixth process step S6, it is determined whether the difference between the temperatures T I , T AThe difference is less than a predefined threshold SW3. If the difference is greater than the other threshold SW3, the process jumps between the fourth process step S4 and the fifth process step S5. However, if it is determined that the difference is less than the other threshold SW3, the vehicle openings F are automatically closed simultaneously in a seventh process step S7 after confirmation and thus activation of the control element 1.10. In particular, if the difference falls below the other threshold SW3, a visual and / or audible recommendation or request to close the vehicle openings F is issued.

[0033] For example, it can then be offered to automatically activate the fan motor 1.8 of the vehicle's air conditioning device 1 in order to raise the interior temperature T. I to lower further.

[0034] This procedure activates a counter that tracks how often the method has been used to reduce CO2 emissions. Based on the number of applications and the corresponding number documented by the counter, CO2 certificates can be applied for, as the application of the method demonstrably reduces CO2 emissions.
