Description

Technical field

[0001] The present invention relates to a sensor arrangement for a vehicle. The invention also relates to a vehicle comprising such a sensor arrangement. More precisely, the present invention relates to a short-range information detection sensor arrangement. background

[0002] Nowadays, vehicles incorporate some type of system for detecting vulnerable road users or providing blind spot information to identify cyclists and other road users alongside vehicles and warn the driver. To prevent accidents, this may become a legal requirement in the future. Short-range information detection sensors are typically used for this purpose. These sensors can include laser radar, ultrasonic sensors, or optical cameras. Depending on where the short-range information detection sensor is located on the vehicle, it may be exposed to heat, for example, from the engine and / or the exhaust system. Combined with the heat from the sensor itself, this can result in high temperatures, which can negatively impact its lifespan and functionality.The short-range information detection sensor may therefore require cooling.

[0003] Document US 10035482 B2 discloses a mounting structure for a near-field information detection sensor attached to the inside of a vehicle fender. The near-field information detection sensor can be arranged in a ventilation duct so that ambient air entering through an opening in the front bumper is directed past the near-field information detection sensor.

[0004] Document DE 10 2018 106 083 A1 discloses a heat sink with at least one fluid guide element. The heat sink comprises a heat collection surface, a heat transfer surface with at least one heat dissipation surface, and at least one fluid guide element. The arrangement of the heat collection surface in operative connection with the heat source causes heat to be dissipated from the heat source through the at least one heat dissipation surface. The at least one fluid guide element directs a fluid away from the heat transfer surface and towards an outer surface of the heat source. Summary of the invention

[0005] Despite known solutions in this area, it is desirable to develop a sensor arrangement that mitigates or at least reduces the disadvantages of the state of the art.

[0006] It is therefore an object of the present invention to provide an advantageous sensor arrangement that facilitates cooling and thereby improves the functionality of the sensor. A further object of the present invention is to achieve an advantageous sensor arrangement that facilitates maintenance and cleaning of the sensor arrangement.

[0007] The tasks mentioned herein are solved by a sensor arrangement and a vehicle comprising such a sensor arrangement, according to the independent claims.

[0008] Therefore, according to one aspect of the invention, a sensor arrangement for a vehicle is provided. The sensor arrangement comprises: at least one near-field information detection sensor, a mounting bracket for attaching the at least one near-field information detection sensor to the vehicle, and a cover for enclosing the near-field information detection sensor, which is attached to the mounting bracket, wherein the mounting bracket comprises a base section on which the at least one near-field information detection sensor is arranged, and at least one cooling section extending beyond the cover, wherein the sensor arrangement is configured to be mounted on the outside of a vehicle body panel such that the at least one cooling section is exposed to ambient air.

[0009] According to another aspect of the invention, a vehicle is provided which includes a sensor arrangement as mentioned above.

[0010] Known short-range information detection sensors are mounted on the inside of the vehicle body panel to protect the sensor. Cooling of the sensor can then be provided by directing ambient air through the vehicle interior to the sensor. Such air ducts can become clogged with dirt from the vehicle environment, and cleaning can be difficult due to poor accessibility. By using a sensor assembly according to the present invention, the short-range information detection sensor is mounted on the outside of the vehicle body panel, which simplifies manufacturing and maintenance and allows the sensor assembly to be installed after the vehicle has been assembled. The mounting bracket used to attach the sensor includes at least one cooling section exposed to ambient air.At least one cooling section will therefore be exposed to an ambient airflow when the vehicle is in motion. In this way, heat is conducted through the base section to the cooling section and thus to the ambient air. Because the cooling section is exposed to the ambient air, the sensor assembly will be cooled by natural convection when the vehicle is stationary. The cooling section can therefore be described as a heat sink. The outer cooling section will be easier to clean since it is located on the outside of the vehicle. This results in more reliable cooling of the sensor, improving its lifespan and functionality. In this way, road safety is enhanced.

[0011] Further problems and new features of the present invention will become apparent to those skilled in the art from the following description and also from the practical implementation of the invention. While the invention is described below, it should be noted that it is not limited to the specific details described. Those skilled in the art who have access to the teaching contained herein will recognize further applications, modifications, and uses in other fields that are within the scope of the invention. Brief description of the drawings

[0012] For a more complete understanding of the present invention, as well as of its further problems and advantages, the detailed description below should be studied together with the accompanying drawings, in which the same reference numerals denote similar objects in different drawings, and in which Fig. 1 schematically represents a vehicle according to an example; Fig. 2 schematically represents a sensor arrangement according to an example; Fig. 3 schematically represents a detail of a sensor arrangement according to an example; Fig. 4a-b schematically illustrates details of a sensor arrangement according to an example; and Fig. 5a-b schematically illustrates a detail of a sensor arrangement according to an example. Detailed description of the drawings

[0013] According to one aspect of the present disclosure, a sensor arrangement for a vehicle is provided. The sensor arrangement comprises: at least one near-field information detection sensor, a mounting for attaching the at least one near-field information detection sensor to the vehicle, and a cover for enclosing the near-field information detection sensor, which is attached to the mounting, wherein the mounting comprises a base section on which the at least one near-field information detection sensor is arranged, and at least one cooling section extending beyond the cover, wherein the sensor arrangement is configured to be attached to the outside of a vehicle sheet such that the at least one cooling section is exposed to ambient air.The fact that at least one cooling section extends beyond the cover means that it extends outside the cover and is therefore not enclosed / covered by it. Therefore, the base section can be defined as the part of the bracket that is covered by the cover, and the at least one cooling section can be defined as the part of the bracket that is not covered by the cover. The sensor assembly is designed to be mounted externally on a vehicle to allow the at least one cooling section to be exposed to ambient air. The sensor assembly can be referred to as a vehicle sensor assembly.

[0014] For the sake of simplicity, the near-area information detection sensor (VID sensor) is referred to herein as the sensor. The sensor disclosed herein is configured as a conventional near-area information detection sensor and may therefore include a detection unit such as a laser, radar, ultrasonic sensor, or optical camera for detecting objects near the vehicle. The sensor may further include a housing that encloses the detection unit. It should therefore be understood that the mounting and cover of the sensor arrangement according to the present disclosure are different from the housing of the individual sensor. The sensor may be arranged in communication with a control device in accordance with conventional vehicle sensors. The sensor arrangement according to the present disclosure may therefore be configured to accommodate multiple near-area information detection sensors.

[0015] The base section of the bracket can have a substantially rectangular shape with a longitudinal extent (length) and a width. The bracket can be configured to be attached to the vehicle body such that the longitudinal extent of the base section is vertical. The base section can comprise an upper end, a lower end, a left side, and a right side. The base section can further comprise a rear side, which is configured to rest against the vehicle body when the sensor assembly is attached to the vehicle. The base section can also comprise a front side opposite the rear side, with the sensor located at the front side. Therefore, the base section can extend longitudinally between its upper and lower ends, and its width can extend between its left and right sides.The base section may include multiple mounting points for attaching the sensor to the base section and multiple mounting points for attaching the bracket to the vehicle. The mounting points may include through-holes designed to interact with fasteners. The base section may also have inclined projections on which the sensor is mounted. The inclined projections may be designed to orient different sensors in different directions. Typically, the inclined projections are angled in different directions for different sensors. The inclined projections may be wedge-shaped.

[0016] The at least one cooling section can be connected to the base section, or it can be integrally formed with the base section. Therefore, the at least one cooling section can be an extension of the base section that is not covered by the cover. The at least one cooling section can thus be arranged flush with the base section in such a way that it rests against the vehicle body panel when the sensor assembly is mounted on the vehicle. The at least one cooling section can be located at the upper end of the base section, at the lower end of the base section, on the left side of the base section, and / or on the right side of the base section. Therefore, the at least one cooling section can extend to the left of the cover, to the right of the cover, above the cover, or below the cover.The sensor arrangement can have at least two cooling sections that extend in different directions beyond the cover.

[0017] The cover is designed to enclose the sensor in a closed position. Therefore, the cover and the base section of the mount together form a volume and surround the sensor. The cover will also cover the base section of the mount. The cover can be attached to the mount in a removable manner. The cover can be attached to the mount in a pivoting manner. The cover can be designed to form an airtight seal with the mount in such a way that air and dust are prevented from reaching the sensor. The shape of the cover can be adapted to the shape of the sensor mounted on the base section. Therefore, if the sensor assembly includes two sensors, the cover can be adapted to the shape of both sensors. The cover can be aerodynamically shaped.Furthermore, the cover can comprise a material transparent to laser light, allowing the transmission of laser light from the sensor's detection unit. The cover can therefore be made of plastic.

[0018] The sensor assembly can be configured to be located in conjunction with a front wheel and / or a muffler of the vehicle. A suitable position for the sensor assembly is on the fender or mudguard surrounding the first front wheel of the vehicle. Therefore, the sensor assembly can be configured to be located on a fender behind a front wheel of the vehicle. If the vehicle has multiple front wheels, the sensor assembly is appropriately located behind the first front wheel. It should be understood that "behind the front wheel" refers to the vehicle's main direction of travel. Behind the front wheel, and specifically within the wheel well formed by the fender, the sensor assembly will be exposed to a higher airflow velocity when the vehicle is in motion. This is due, for example, to turbulence caused by the wheel.Therefore, positioning the sensor assembly on the fender behind the front wheel increases the cooling of at least one cooling section and thus of the sensor itself. On modern trucks, the muffler may also be located near the front wheels. The muffler typically houses the exhaust aftertreatment system and can therefore generate high temperatures. If the sensor assembly is positioned close to the muffler, it can be heated by the muffler. Excessive sensor temperature can negatively impact the sensor's lifespan and functionality, making cooling essential. Therefore, if the sensor assembly is designed to be positioned next to a muffler, the cooling section of the bracket can be positioned so that it is not directly exposed to the muffler's heat.The cooling section can therefore extend away from the silencer.

[0019] The bracket can be made of a thermally conductive material. For example, the bracket can be made of aluminum. In this way, heat from the sensor, as well as heat from the engine or the muffler, can be conducted through the base section to the outside, where at least one cooling section is located.

[0020] According to one example, the at least one cooling section extends substantially perpendicular to the base section. The sensor assembly can be configured such that the cooling section extends into a wheel well of the vehicle. The wheel well is an area enclosed by the mudguard / fender. By arranging the cooling section to extend into the wheel well, it will be exposed to higher flow velocities, thus improving the cooling of the sensor assembly. The cooling section can extend perpendicularly from the rear of the base section. The at least one cooling section can therefore be positioned slightly behind the wheel. The at least one cooling section can therefore be positioned to point forward in the main direction of travel of the vehicle.The at least one cooling section in this example can be referred to as a cooling flange. The cooling flange can extend along at least a portion of the longitudinal extent of the base section. Alternatively, the support comprises multiple cooling sections / cooling flanges, each extending along a portion of the longitudinal extent of the base section. In one example, the at least one cooling section is located on the right side of the base section and therefore extends perpendicularly from the right side of the base section. In another example, the at least one cooling section is configured to extend perpendicularly from the rear side of the base section at a distance from both the right and left sides of the base section. The cooling flange(s) can have an L-shaped, I-shaped, or T-shaped cross-section.By using an L-shaped or T-shaped cooling flange, the heat-conducting surface of the cooling section is increased, and the cooling performance is improved.

[0021] According to another example, the at least one cooling section is configured to create a gap between the cooling section and the vehicle body panel when the sensor assembly is attached to the vehicle. This allows ambient air to flow between the cooling section and the vehicle body panel. The at least one cooling section can therefore include a front cooling surface facing outwards away from the vehicle body panel and a rear cooling surface facing inwards towards the vehicle body panel. This improves cooling. The cooling section can be configured with its rear cooling surface in a different plane than the rear side of the base section. This allows a gap to form between the cooling section and the vehicle body panel when the sensor assembly is mounted on the vehicle.The cooling section can therefore be thinner than the base section. The gap formed between the cooling section and the vehicle body panel can be between 10 and 20 millimeters. The cooling section can therefore be designed to create a gap in the range of 10 to 20 millimeters between itself and the vehicle body panel. The cooling section with two cooling surfaces can be located at the lower end or the upper end of the base section.

[0022] For example, the cooling section can be configured so that its size increases from the left side of the base section to the right side. The cooling section can therefore be configured so that its size increases in the direction of the main direction of travel. This increase in size means that the area of ​​the cooling surface of the cooling section increases. The main direction of travel of the vehicle can be referred to as the forward direction, and the opposite direction as the reverse direction. The cooling surface(s) of the cooling section can therefore become progressively larger towards the wheel and thus in the forward direction. In other words, the cooling section can taper in the reverse direction. Typically, a silencer is located behind the sensor assembly.By designing the cooling section in such a way that its size increases in a direction away from the silencer, the risk of the cooling section being exposed to and absorbing heat from the silencer is minimized.

[0023] The sensor assembly can further include a protective grille designed to at least partially enclose the at least one cooling section. The at least one cooling section of the mount can therefore be completely or partially enclosed by a protective grille. This is particularly advantageous if the sensor assembly is located at a position on the vehicle where the cooling section may be exposed to stone impacts. This can be the case if the sensor assembly is located in conjunction with a vehicle wheel. The protective grille can be designed to prevent solid objects (gravel, stones, etc.) from causing mechanical wear to the cooling section. The protective grille can also be designed to allow ambient air to pass through it.

[0024] According to one example, the sensor assembly further includes a thermally conductive material positioned between the sensor and the base section. This thermally conductive material can be silicone or a similar material. It can also be referred to as a thermal gap filler. In this way, heat from the sensor itself can be transferred to the mount and thus to at least one cooling section.

[0025] According to another aspect of the present disclosure, a vehicle is provided. The vehicle includes a sensor arrangement as disclosed herein. All features and examples mentioned herein relating to the aspect of the sensor arrangement are also applicable to the aspect of the vehicle in the present disclosure.Therefore, the vehicle comprises a sensor assembly including at least one short-range information detection sensor, a mounting bracket for attaching the at least one short-range information detection sensor to the vehicle, and a cover for enclosing the short-range information detection sensor, which is attached to the mounting bracket. The mounting bracket includes a base section on which the at least one short-range information detection sensor is arranged and at least one cooling section extending beyond the cover. The sensor assembly is configured to be mounted on the outside of a vehicle body panel such that the at least one cooling section is exposed to ambient air. The sensor assembly may be arranged in association with a front wheel and / or a muffler of the vehicle. For example, the sensor assembly is arranged on a fender behind a front wheel of the vehicle.

[0026] The present revelation will now be explained in more detail with reference to the accompanying drawings.

[0027] Fig. Figure 1 schematically shows a side view of a vehicle 1 comprising a drive unit 2. The vehicle 1 also includes a silencer 4. The vehicle 1 travels in a main direction of travel D, which is illustrated by an arrow. The vehicle 1 further includes a sensor assembly 10, which is attached to a vehicle body panel 6 of the vehicle. The sensor assembly 10 is further described in the Fig. 2, Fig. 3, Fig. 4a-b and Fig. Described in sections 5a-b. Vehicle 1 can be a heavy vehicle, for example a truck or a bus. Alternatively, vehicle 1 can be a passenger vehicle. Vehicle 1 can be manually operated, remotely controlled, or autonomously operated.

[0028] Fig. Figure 2 schematically represents a sensor arrangement 10 according to an example. The sensor arrangement 10 is attached to a vehicle body panel 6 of a vehicle 1. The vehicle 1 can be driven as shown in Fig. Figure 1 discloses the configuration of the sensor assembly. The sensor assembly comprises: at least one short-range information detection sensor 12, a mounting bracket 20 for attaching the at least one short-range information detection sensor 12 to the vehicle 1; and a cover 30 for enclosing the short-range information detection sensor 12, which is attached to the mounting bracket 20. The mounting bracket 20 comprises a base section 22 on which the at least one short-range information detection sensor 12 is arranged, and at least one cooling section 24 extending beyond the cover 30. According to this example, the mounting bracket 20 comprises two cooling sections 24, one at an upper end of the base section 22 and one at a lower end of the base section 22. The at least one cooling section 24 can be connected to the base section 22, or the at least one cooling section 24 can be formed integrally with the base section 22.Therefore, at least one cooling section 24 can be an extension of the base section 22 that is not covered by the cover 30.

[0029] According to this example, the sensor arrangement 10 also includes two short-range information detection sensors 12, which are hereby referred to as the sensors 12. However, it should be understood that the sensor arrangement 10 can include any number of short-range information detection sensors 12. The sensor arrangement 10 is mounted on the outside of the vehicle body 6 such that the cooling sections 24 are exposed to ambient air. Therefore, an ambient airflow will cool the cooling sections 24 and thus the sensors 12 when the vehicle 1 is in motion.

[0030] According to this example, the sensor assembly 10 is shown arranged in connection with a front wheel 8 and a silencer 4 of the vehicle 1. The sensor assembly 10 can therefore be arranged on the fender or mudguard next to the wheel arch 9. Typically, the sensor assembly 10 is arranged behind the front wheel 8.

[0031] Fig. Figure 3 schematically illustrates a detail of a sensor arrangement 10 according to an example. The sensor arrangement 10 can be configured as shown in Fig. Figure 2 discloses the configuration. This figure shows an example of the cover 30, which protects the sensor 12. The cover 30 is configured to enclose the sensor 12 together with the base section 22 in a closed position. The cover 30 is therefore configured to cover the base section 22 of the mount 20. The cover 30 can be removably attached to the mount 20. The cover 30 can be pivotally attached to the mount 20. The cover 30 can be configured to form an airtight seal with the mount 20 in such a way that air and dust are prevented from reaching the sensor 12. The shape of the cover 30 can be adapted to the shape of the sensor 12, which is arranged on the base section 22. According to this example, the sensor arrangement 10 comprises two sensors 12, and the cover 30 is therefore adapted to the shape of the two sensors 12. The cover 30 can be aerodynamically shaped.Furthermore, the cover can include 30 plastic, which allows the transmission of laser light from the detection unit of the sensor 12.

[0032] Fig. 4a and Fig. Figure 4b schematically illustrates details of a sensor arrangement 10 according to two examples. The sensor arrangement 10 can be configured as shown in Fig. 2 or Fig. Figure 3 reveals its design. These figures represent two examples of the bracket 20. The bracket 20 comprises a thermally conductive material, such as aluminum. In this way, heat from the sensor 12, as well as heat from the motor 2 or the silencer, can be conducted through the bracket 20 to the outside, to at least one cooling section 24.

[0033] The base section 22 of the bracket 20 can be substantially perpendicular to a longitudinal extent (length) L and a width W. The base section 22 can comprise an upper end 23' and a lower end 23". The base section 22 can further comprise a left side 25' and a right side 25". The at least one cooling section 24 can be arranged at the upper end 23', at the lower end 23", at the left side 25', and / or at the right side 25" of the base section 22. The base section 22 can also comprise a rear side 27, which is configured to abut the vehicle body panel 6 when the sensor assembly 10 is attached to the vehicle 1.

[0034] The base section 22 can include multiple attachment points 40 for attaching the sensor(s) 12 to the base section 22, as well as multiple attachment points 42 for attaching the bracket 20 to the vehicle 1. The base section 22 can also include inclined projections 46 on which the sensor(s) 12 are to be arranged. The inclined projections 46 can be configured to orient the sensor(s) 12 in different directions. The inclined projections 46 can be wedge-shaped.

[0035] In Fig. 4a The at least one cooling section 24 extends substantially perpendicularly to the base section 22. The cooling section 24 can extend perpendicularly from the rear side 27 of the base section 22. The sensor arrangement 10 is then configured to be mounted such that the cooling section 24 extends into a wheel arch 9 of the vehicle 1. The at least one cooling section 24 can then be arranged slightly behind the wheel 8. The at least one cooling section 24 can therefore be arranged such that it points forward in the main direction of travel D of the vehicle 1. The cooling section 24 can extend along at least a part of the longitudinal extent L of the base section 22. According to this example, the cooling section 24 is arranged on the right side 25" of the base section 22, but it should be understood that this is merely an example.The cooling section 24 can be configured to extend from the rear side 27 of the base section at any distance from the right side 25". The support 20 can also include a second cooling section 24 (shown by dotted lines) at the upper end 23' of the base section 22.

[0036] Fig. Figure 4b schematically depicts a holder 20 for a sensor arrangement 10 according to an example. The holder 20 can be configured as shown in Fig. Figure 4a discloses the cooling section as follows: it must be designed and therefore comprise a cooling section 24 extending substantially perpendicular to the base section 22. According to this example, the cooling section 24 has an L-shaped cross-section. This increases the heat-conducting surface area of ​​the cooling section 24.

[0037] Fig. 5a and Fig. Figure 5b schematically depicts different views of a detail of a sensor arrangement 10 according to an example. The sensor arrangement 10 can be viewed as shown in Fig. 2 or Fig. Figure 3 reveals how the sensor assembly is designed. These figures show two examples of the bracket 20 of the sensor assembly 10. The bracket 20 comprises a thermally conductive material, such as aluminum. In this way, heat from the sensor 12 and also heat from the motor 2 or the silencer 20 is conducted through the bracket 20 to the outside, to the at least one cooling section 24.

[0038] The base section 22 can comprise an upper end 23' and a lower end 23". The base section 22 can further comprise a left side 25' and a right side 25". The base section 22 can also comprise a rear side 27, which is configured to rest against the vehicle body 6 when the sensor assembly 10 is attached to the vehicle 1. The base section 22 can comprise multiple attachment points 40 for attaching the sensor(s) 12 to the base section 22, as well as multiple attachment points 42 for attaching the mounting bracket 20 to the vehicle 1. The base section 22 can further comprise inclined projections 46 on which the sensor(s) 12 are to be arranged. The inclined projections 46 can be configured to orient the sensor(s) 12 in different directions.

[0039] According to this example, the cooling section 24 is configured to form a gap between the cooling section 24 and the vehicle body 6 when the sensor assembly 10 is attached to the vehicle 1. This allows ambient air to flow between the cooling section 24 and the vehicle body 6. In the figures, the cooling section 24 is arranged at the lower end 23" of the base section 22. However, it is understood that a similar cooling section 24 can additionally or alternatively be arranged at the upper end 23' of the base section 22. The cooling section 24 can therefore comprise a front cooling surface 24', which is configured to face outwards, and a rear cooling surface 24', which is configured to face inwards towards the vehicle body 6.The gap between the vehicle sheet metal and the cooling section 24 can be achieved by having the rear side 27 of the base section 2 and the rear cooling surface 24" of the cooling section 24 lie in different planes. The cooling section 24 can therefore have a lesser thickness than the base section 24. The cooling section can be configured to form a gap of 10 to 20 millimeters between the cooling section and the vehicle sheet metal 6.

[0040] According to this example, the cooling section 24 is further configured such that the cooling surface(s) 24', 24' become progressively larger in the direction of the main travel direction D as the sensor assembly is attached to the vehicle 1. The size of the cooling section 24 can therefore increase from the left side 25' to the right side 25" of the base section 22. In this way, the risk of the cooling section 24 being exposed to and absorbing heat from a silencer 4 is minimized.

[0041] The foregoing description of preferred embodiments of the present invention is provided for illustrative and descriptive purposes. It is not intended to be exhaustive or to limit the invention to the described variants. Many modifications and variations will be obvious to those skilled in the art. The embodiments have been selected and described to best explain the principles of the invention and its practical applications, and to enable those skilled in the art to understand the invention in various embodiments and with various modifications appropriate for the intended use.
