Description

Technical Field

[0001] The invention relates to a vehicle device for detecting a crosswind ratio, the device comprising two thermoplanar elements and a control unit, a method for detecting a crosswind ratio for such a device, and a vehicle having such a device. Background Art

[0002] Crosswinds pose a significant safety risk in road traffic because they can cause vehicles to veer off their lanes or even off the road, leading to serious accidents. Large vehicles such as trucks and box trucks, buses, and caravans are particularly at risk. However, even smaller passenger cars can be deviated from their path, particularly due to sudden crosswinds, such as on bridges or when leaving the wind shadow of a truck. Due to human reaction times, corrective action is often too late. Therefore, efficient sensors are needed for vehicles that can detect crosswinds in a fraction of the human reaction time.

[0003] Traditional wind sensors have an impeller for measuring wind force and a wind vane for determining wind direction. These are unsuitable for use on road and rail vehicles. Ultrasonic wind sensors for use on drones, aircraft, vehicles, ships, or weather stations are also known. However, these wind sensors use complex measurement methods based on ultrasonic resonance. Consequently, they are expensive and form protruding components on the vehicle roof, negatively impacting the vehicle's profile and air resistance. Summary of the Invention

[0004] It is therefore an object of the present invention to overcome or at least reduce the disadvantages of the prior art and to provide a side wind sensor for a vehicle which is particularly effective and inexpensive.

[0005] The object of the invention is achieved by the subject matter of the independent claims. Preferred developments are the subject matter of the referenced dependent claims.

[0006] A first aspect of the present disclosure relates to a vehicle device for detecting a crosswind ratio. Within the meaning of the present disclosure, a vehicle is preferably a motor vehicle, such as a car, truck, bus, motorhome, rail vehicle, motorcycle, moped, or electric bicycle or electric scooter. A crosswind within the meaning of the present disclosure preferably refers to wind acting laterally on the vehicle, in particular with respect to the longitudinal extent (longitudinal direction) and / or the direction of travel of the vehicle. The crosswind ratio is preferably a measured value from which inferences about the crosswind and its effect on the vehicle can be drawn.

[0007] The device comprises a first electrothermal planar element and a second electrothermal planar element. The electrothermal planar elements are preferably planar sensors that are contacted on opposite sides and warm up when an electric current is applied. The electrothermal planar elements are preferably constructed from metal, ceramic, or organic materials. Preferably, the first and / or second electrothermal planar elements comprise heating surfaces and / or heating wires. For example, the electrothermal planar elements can also be fabricated from heating wires, such as an array of heating wires, which can be a cost-effective solution compared to planar deposited electrothermal planar element substrates.

[0008] The device also includes a control unit for controllably or adjustably providing heating power to each of the two thermal planar elements. The control unit preferably controls or adjusts the heating power by applying a voltage to the thermal planar elements and, more preferably, detecting the heating power of each thermal planar element. The control unit is further configured to determine a crosswind ratio based on the heating power and / or surface temperature of the first and second thermal planar elements. The control unit is preferably configured to determine the crosswind ratio based on differences in heating power at the same surface temperature or differences in surface temperature at the same heating power.

[0009] The device is designed to be mounted on a vehicle so that the surfaces of the two thermal planar elements are arranged symmetrically with respect to the direction of travel and are aligned with the sides of the vehicle. In other words, the two thermal planar elements are mounted on the vehicle so that their surfaces face either side of the vehicle—one to the right and the other to the left—to facilitate cooling by side winds. In a preferred embodiment, the thermal planar elements are mounted parallel to the direction of travel. The device also preferably includes a partition wall between the two thermal planar elements. This ensures that the thermal planar elements are cooled only by wind blowing from the sides of the vehicle.

[0010] The device for detecting a crosswind ratio advantageously provides a sensor that can detect crosswind particularly quickly. The advantageously short reaction time is achieved by the low thermal inertia of the thermal planar element, which results in a very large area of ​​the thermal planar element compared to its thermal mass.

[0011] In a preferred embodiment, the first and / or second thermal planar element is configured as a conductive layer deposited flat on a substrate. The conductive layer is preferably applied to the substrate by screen printing, evaporation, and / or vacuum coating. The substrate preferably comprises an insulating material. This material is preferably electrically and thermally insulating, such as plastic or ceramic.

[0012] The device is therefore advantageously particularly simple in design and manufacture, which makes it particularly inexpensive and reliable. Advantageously, the thermal planar element can also be easily integrated into the surface of a component or vehicle body due to its small, flat design, thereby having little impact on the vehicle's appearance, in particular its air resistance.

[0013] In this embodiment, the base plate is preferably designed as a partition wall, having one of the flat thermal elements on each side. Preferably, the base plate is vertically positioned and arranged on the vehicle roof, parallel to the direction of travel. The height of the base plate is preferably less than 10 cm, more preferably less than 5 cm, and particularly preferably less than 2 cm.

[0014] In this embodiment, the device is preferably arranged on the vehicle roof as a separate component, which advantageously makes it easy to assemble and retrofit. The component advantageously has a small height, so that the appearance and air resistance of the vehicle are only slightly affected.

[0015] In another preferred embodiment, the first and second thermal planar elements comprise PTC resistors. Preferably, both thermal planar elements are composed of a material with a positive temperature coefficient. Preferably, the control unit is configured to heat the thermal planar elements with the same constant voltage and to determine the crosswind ratio based on the difference in heating power. When the thermal planar elements with PTC resistors are cooled by crosswind, this results in a decrease in resistance and, consequently, an increase in heating power. Therefore, in this embodiment, the crosswind ratio can advantageously be directly inferred from the difference in heating power, without the need for temperature measurement.

[0016] It is also preferred that the first and second thermal planar elements have further thermal resistors, for example NTC resistors.

[0017] Another preferred embodiment of the device includes a first temperature sensor located on the first planar thermal element and a second temperature sensor located on the second planar thermal element. The control unit is preferably configured to determine a crosswind ratio based on the surface temperatures detected by the first and second temperature sensors. Preferably, the control unit is configured to determine the crosswind ratio based on differences in surface temperatures at the same heating power.

[0018] In another embodiment, the thermally planar element is integrated into the vehicle surface. Preferably, the thermally planar element is arranged flush with the vehicle surface. The thermally planar element is preferably arranged and integrated on one side of the vehicle body, for example, on the B-pillar or C-pillar. Preferably, the thermally planar element here also has an additional decorative function, for example, as a design element or logo.

[0019] Likewise, the planar thermal elements are preferably integrated into vehicle components on the roof, arranged primarily vertically and pointing toward the sides of the vehicle, such as into antenna units (shark fin antennas), lighting units, or roof rails. Each planar thermal element preferably has its own substrate for electrical and thermal insulation. The substrate is preferably integrated into the vehicle surface or a portion of the vehicle surface.

[0020] The flush surface integration of the thermoplanar element advantageously leads to reduced air turbulence at the sensor. Another advantage is the lower risk of contamination, which results in a lower susceptibility to errors.

[0021] It is also preferred that the planar thermal element be arranged so as to be recessed in the vehicle surface. This advantageously reduces the amount of draft acting on the planar thermal element. It is also preferred that the planar thermal element be arranged in an existing recess in the vehicle surface, such as in a door handle recess, or behind a protrusion in the vehicle surface, such as behind the cab of a truck, to reduce draft.

[0022] Another preferred embodiment of the device further includes a structure for shielding against direct sunlight, precipitation, and / or wind. Preferably, the base plate has lateral projections on both thermal planar elements. This advantageously reduces interfering factors that, in addition to crosswind, also influence the temperature of the thermal planar elements and could lead to an erroneous determination of the crosswind ratio.

[0023] In another preferred embodiment, the device further comprises a first light sensor and / or rain sensor located on the first planar thermal element, and a second light sensor and / or rain sensor located on the second planar thermal element. The control unit is preferably configured to determine the crosswind based on the signals detected by the sensors. In other words, the control unit also determines the extent to which the planar thermal elements are heated by sunlight or cooled by precipitation, respectively. The control unit then determines the crosswind ratio based on the heating power of the heating elements and / or the surface temperature, taking into account the influence of sunlight and / or precipitation on the surface temperature. This advantageously avoids erroneous determinations of the crosswind ratio.

[0024] A second aspect of the present disclosure relates to a method for a device for detecting a crosswind ratio. The device comprises a first and a second thermal planar element. Preferably, the device is the device for detecting a crosswind ratio described above.

[0025] As a first step, the method includes heating first and second thermal planar elements. The heating of the thermal planar elements is achieved by applying a voltage to each thermal planar element. In another method step, the heating power and / or surface temperature of the two thermal planar elements are detected. Another method step involves determining a crosswind ratio based on the different heating power and / or surface temperatures of the two thermal planar elements. This method advantageously provides a particularly fast and error-free method for determining the crosswind ratio.

[0026] In a preferred embodiment of the method, the heating is carried out at a constant voltage. The crosswind ratio is preferably determined based on the difference in heating power. Preferably, the first and second thermal plane elements have PTC resistors. Preferably, the two thermal plane elements are composed of a material with a positive temperature coefficient. When the thermal plane element with the PTC resistor is cooled by the crosswind, this leads to a decrease in resistance and thus an increase in heating power. Therefore, in this embodiment, the crosswind ratio can be advantageously derived directly from the difference in heating power without the need for temperature measurement. In addition, in this embodiment, it is advantageous that the PTC element operates at a relatively low temperature, or the maximum temperature is inherently limited due to the increase in resistance, which improves operational safety while improving the efficiency of the equipment.

[0027] As a further step, a similarly preferred embodiment of the method includes determining a first surface temperature using a first temperature sensor on the first thermal planar element. Furthermore, in this method step, a second surface temperature is determined using a second temperature sensor on the second thermal planar element. The thermal planar elements are preferably heated so that the first heating power corresponds to the second heating power. The crosswind ratio is preferably determined based on the difference in surface temperature, which results in asymmetric cooling of the thermal planar elements.

[0028] Another preferred embodiment includes, as a further method step, determining a first surface temperature using a first temperature sensor on the first thermal planar element and determining a second surface temperature using a second temperature sensor on the second thermal planar element. In another method step, the heating power is preferably adjusted based on the first and second surface temperatures until the first and second surface temperatures match. Once the thermal planar elements have reached the same surface temperature, the crosswind is preferably determined based on the difference in heating power.

[0029] Another preferred embodiment of the method includes, as a further step, detecting the first signal using a first light sensor or rain sensor on the first thermal planar element, and determining the second signal using a second light sensor or rain sensor on the second thermal planar element. Preferably, the first signal is determined using the first light sensor on the first thermal planar element, and the second signal is determined using the second light sensor on the second thermal planar element. Also preferably, the first signal is determined using a first rain sensor on the first thermal planar element, and the second signal is determined using a second rain sensor on the second thermal planar element.

[0030] Preferably, the crosswind is also determined based on the first and second signals. The crosswind is preferably determined based on the heating power and / or surface temperature of the heating element and the first and second signals. In other words, the degree to which the thermal planar element is heated by sunlight or cooled by precipitation, respectively, is additionally determined. The crosswind ratio is then determined based on the heating power and / or surface temperature of the heating element, while also taking into account the effects of sunlight and / or precipitation on the surface temperature. This advantageously avoids erroneous determinations of the crosswind ratio.

[0031] Another aspect of the present disclosure relates to a vehicle. The vehicle is preferably a motor vehicle, such as a car, truck, bus, recreational vehicle, rail vehicle, motorcycle, moped, electric bicycle, or electric scooter. Preferably, the vehicle is configured to perform the above-described method. To this end, the vehicle includes the device for detecting the crosswind ratio as described above.

[0032] In a preferred embodiment of the vehicle according to the present disclosure, the control unit is further configured to influence the vehicle's steering system, drive system, and / or braking system based on the determined crosswind ratio. To this end, the control unit preferably communicates with the vehicle's steering system, drive system, and / or braking system control units. Alternatively, the control unit is preferably configured as a central control unit of the vehicle, which, in addition to the aforementioned features, is configured to operate all controllable systems of the vehicle.

[0033] Preferably, the control unit is configured to influence the vehicle's steering system so that the vehicle's yaw is compensated for by the crosswind. Similarly, preferably, the control unit is configured to influence the vehicle's drive system so that the vehicle's speed is reduced as a function of the crosswind ratio. Furthermore, preferably, the control unit is configured to influence the vehicle's braking system so that the vehicle's speed is reduced as a function of the crosswind ratio and / or to initiate emergency braking when the crosswind ratio exceeds a predetermined limit value. The control unit is further preferably configured to control an output device of the vehicle based on the determined crosswind ratio. Preferably, the control unit is configured to control the output device to issue a warning when the crosswind ratio exceeds another predetermined limit value.

[0034] In this embodiment, the vehicle is advantageously configured to automatically react to crosswinds, which improves driving safety, particularly in autonomous vehicles. Advantageously, the device's reaction time is significantly lower than a person's, so the automated reaction occurs much faster than a human driver could.

[0035] Another aspect of the present disclosure relates to a computer program product having instructions, which, when executed by a computer (such as the above-mentioned control unit), cause the computer to perform the above-mentioned method.

[0036] Unless stated otherwise in individual cases, the various embodiments of the invention mentioned in this application can be advantageously combined with one another.

[0045] Figure 1 A schematic diagram of a device 100 for a vehicle, in particular a motor vehicle, for detecting a side wind ratio according to one embodiment is shown.

[0046] The device 100 has a first electrothermal planar element 101 and a second electrothermal planar element 102. The electrothermal planar elements 101, 102 are in particular flat sensors which are each contact-connected on two opposite sides and which warm up when an electric current is applied.

[0047] Device 100 further includes a control unit 103 connected to thermal planar elements 101 and 102. Control unit 103 is configured to controllably or variably provide heating power to each of thermal planar elements 101 and 102, particularly by applying a voltage and detecting the heating power. Control unit 103 is further configured to determine a crosswind ratio based on the heating power and / or the surface temperature of first and second thermal planar elements 101 and 102. To determine the surface temperature, the device further includes two temperature sensors (not shown), each mounted on one of thermal planar elements 101 and 102 and in communication with control unit 103.

[0048] Specifically, the control unit 103 is configured to determine the crosswind ratio based on a difference in heating power at the same surface temperature or the same voltage, and to determine the crosswind ratio based on a difference in surface temperature at the same heating power.

[0049] The device 100 can be mounted on a vehicle in such a way that the surfaces of the thermal planar elements 101 , 102 are arranged symmetrically with respect to the direction of travel and are aligned with the sides of the vehicle, respectively, so that cooling by side wind is possible.

[0050] Figure 2 A schematic flow chart of a method 200 of a device for detecting a crosswind ratio, in particular a device as described above, according to one embodiment is shown.

[0051] As a first step 201, the method 200 includes heating first and second thermal planar elements. Here, the thermal planar elements are heated by applying a voltage across each thermal planar element.

[0052] In a further method step 202 , the heating power and / or the surface temperature of the two thermal planar elements are detected.

[0053] Another step 203 of the method involves determining a crosswind ratio based on the different heating powers and / or surface temperatures of the two thermal planar elements detected in the previous method step 202. Specifically, the crosswind ratio is determined based on the difference in heating power at the same surface temperature and / or the same voltage. However, the crosswind ratio can also be determined based on the difference in surface temperature at the same heating power.

[0054] Figure 3 A schematic diagram of a vehicle 300 is shown according to one embodiment, particularly configured to perform Figure 2 The vehicle 300 of the method 200. The vehicle 300 has the Figure 1 The device 100 , in particular the control unit 103 as described above and the two thermal planar elements 101 , 102 as described above.

[0055] The control unit 103 of the vehicle 300 has an internal memory (not shown) and at least one CPU (not shown), which communicate with each other, for example, via a suitable data bus. The internal memory contains commands that, when executed by the CPU, cause the control unit 103 to execute Figure 2 Steps 201 to 203 of method 200 are used to determine the crosswind ratio.

[0056] Control unit 103 is further configured to control steering system 303, drive system 304, and brake system 305 of vehicle 300, for example, via one or more corresponding CAN connections, one or more corresponding SPI connections, or other suitable data connections. In particular, control unit 103 is configured to influence steering system 303, drive system 304, and brake system 305 based on the determined crosswind ratio.

[0057] In particular, control unit 103 is configured to influence steering system 303 of vehicle 300 so that the side wind compensates for the yaw of vehicle 300. Furthermore, control unit 103 is configured to influence drive system 304 of vehicle 300 so that the speed of vehicle 300 decreases as a function of the magnitude of the side wind ratio. Furthermore, control unit 103 is configured to influence braking system 305 of vehicle 300 so that the speed of vehicle 300 decreases as a function of the magnitude of the side wind ratio and to initiate emergency braking when the side wind ratio exceeds a predetermined limit value.

[0058] Figure 4 and Figure 5 Different views of a portion of a device for detecting a crosswind ratio according to one embodiment are shown. Figure 4 Shows a top view, Figure 5 A side view is shown.

[0059] The first and second planar thermal elements 101, 102 are each configured as a planar, deposited conductive layer on a substrate 104. The planar thermal elements 101, 102 are applied to the substrate 104, in particular, by screen printing, evaporation, or vacuum coating. The substrate 104 is composed of an electrically and thermally insulating material, such as plastic or ceramic. In particular, the substrate 104 is configured as a partition wall, each having one of the planar thermal elements 101, 102 on either side. The substrate 104 is arranged vertically and parallel to the direction of travel on a vehicle surface 301, in particular, on the vehicle roof.

[0060] Figure 6 A top view of a portion of a device for detecting a crosswind ratio according to another embodiment is shown. Figure 4 and Figure 5In addition to the features shown, in the illustrated embodiment, base plate 104 has a lateral protrusion above both thermal planar elements 101 and 102. This serves as structure 105, providing a shield from direct sunlight or precipitation. This advantageously reduces interfering factors that, in addition to crosswinds, also influence the temperature of thermal planar elements 101 and 102 and could lead to an erroneous determination of the crosswind ratio.

[0061] Figure 7 A side view of a portion of a device for detecting a crosswind ratio according to another embodiment is shown. In this embodiment, the thermal planar elements 101, 102 are integrated into the components of the vehicle in such a way that they are arranged predominantly vertically and each face one side of the vehicle. In particular, the thermal planar elements 101, 102 are integrated into an antenna unit 302 of the vehicle, a so-called shark fin antenna 302, which is located on the vehicle surface 301, in particular on the roof. Each of the thermal planar elements 101, 102 has its own substrate 104 for electrical and thermal insulation. Due to the side view, the thermal planar elements 101, 102 are integrated into the components of the vehicle in such a way that they are arranged predominantly vertically and each face one side of the vehicle. In particular, the thermal planar elements 101, 102 are integrated into an antenna unit 302 of the vehicle, a so-called shark fin antenna 302, which is located on the vehicle surface 301, in particular on the roof. Figure 7 Only the first thermal plane element 101 with the corresponding base plate 104 can be seen.
