Definitions

• Roof for a motor vehicle comprising a sensor module
• the invention relates to a roof for a motor vehicle, in particular for a passenger car, comprising the features of the preamble of patent claim 1.
• Such a roof is known from practice and can in particular be part of an autonomously or partially autonomously driving motor vehicle.
• Such motor vehicles are becoming more widespread.
• a vehicle control system In order for autonomous or semi-autonomous driving to meet high safety requirements, a vehicle control system must be connected to a large number of environment sensors, by means of which the vehicle environment can be recorded so that the traffic situation can be determined and analyzed based on the respective measurement result.
• sensor modules with environment sensors for monitoring and recording the vehicle environment are also attached to the vehicle roof, since the vehicle roof is generally the highest elevation of a vehicle from which the vehicle environment can be clearly seen.
• sensor modules which can include LiDAR sensors, radar sensors, optical sensors such as cameras or the like as environment sensors, have housings which are made of metal in a dimensionally stable manner and are heavy. This requires additional measures on the roof concerned so that the existing safety requirements can be met. Additional struts and additional sheets have to be integrated in order to ensure adequate crash safety and to pass the roof indentation tests specified for this. In a roof crush test, the raised contact points formed by the sensor modules must absorb forces and dissipate them via the vehicle structure, since otherwise there would be the risk that the sensor modules would be pressed into the vehicle interior and endanger vehicle occupants. The measures used to date on the vehicle body to prevent this make the roof as a whole heavy and expensive.
• the invention is based on the object of creating a roof of the type mentioned in the introduction, which is provided with at least one sensor module comprising an environment sensor and does not require complex reinforcement measures to ensure occupant safety.
• the at least one sensor module is arranged on the support structure in such a way that its upper or upper boundary surface or even a roof skin section located above the sensor module protrudes only slightly beyond a roof line that, in a comparable roof without a sensor module would be given.
• Special reinforcement measures in the area of the support structure and in the area of the sensor modules can thus at least largely be dispensed with. As a result, the integration of the sensor module into the roof does not result in any weight-intensive and cost-intensive additional measures.
• the reference roof impression plane defined here is a virtual plane that lies tangentially on a roof side rail and, in accordance with legal requirements, is inclined by a first angle in the transverse direction of the roof and by a second angle in the longitudinal direction of the roof.
• the first angle is preferably between 20 ° and 30 °, in particular around 25 °.
• the second angle is preferably between 2 ° and 10 °, in particular around 5 °.
• each of the corner areas that is, one in each of the two the front corner areas of the roof and one in each of the two rear corner areas of the roof.
• a large-area stamp is brought closer to the roof, plane-parallel to the reference roof impression plane.
• the first contact between the punch face and the sensor module or a roof skin section above the sensor module, which is to be assigned to the sensor module takes place shortly before reaching, ideally only after the punch has reached the reference roof impression plane.
• the first contact defines a first contact plane, which is also aligned parallel to the reference roof impression plane.
• the environment sensor of the roof according to the invention can be designed in many ways and in particular comprise a LiDAR sensor, a radar sensor, an optical sensor, such as a camera, and / or the like.
• roof according to the invention which can be designed as an integrated compact roof module that can be placed as a unit on a vehicle body shell
• sensor modules and components are used in particular that have a low overall height and / or the sensor modules and components are connected and integrated in such a way that so that they do not or only partially protrude over the roof impression level.
• the sensor module is connected to or integrated into the support structure, which can be formed by a frame or bow of the roof designed as a roof module itself or also by the vehicle shell.
• the sensor module is attached to the support structure in the lowered position, wherein the support structure can then have a lowered mounting base for the sensor module.
• Holders and other components of the sensor module or of other vehicle elements that are required to implement autonomous driving can also be integrated into the roof.
• the sensor module itself can be provided with a cover or a cap for protection, which can be part of the roof skin and can define the first contact plane.
• the sensor module is covered by the roof skin, which then forms a protection for the sensor module.
• the roof skin can be made in one piece or in several parts.
• the upper boundary surface of the sensor module is preferably at a right angle to the reference roof impression plane at a maximum of approximately 12.5 cm, that is to say approximately 5 inches.
• the first contact plane and the reference roof impression plane therefore preferably have a maximum distance of 12.5 cm.
• the sensor module which forms a roof structure in the broadest sense, thus projects only slightly beyond a basic roof line, which represents a virtual line that would form the roof line of a roof without a sensor module.
• the sensor module is, in particular, an integrated part of the roof according to the invention and is covered by the roof skin, which is, for example, one-piece or multi-part. So that the environment sensor can detect the vehicle environment or the vehicle environment, the roof skin is expediently designed with a viewing window for the environment sensor that is transparent at least for the wavelengths used by the environment sensor, for example for a wavelength range between 200 nm and 2000 nm and also for radar radiation .
• the material of the roof skin can also be selected such that it is permeable to the required wavelength ranges, so that a separate viewing window or a separate viewing window area can be dispensed with.
• the roof according to the invention can be a pure fixed roof or also be provided with a roof opening system which comprises a cover element by means of which a roof opening can be opened or closed as desired.
• the roof according to the invention is a roof of a passenger car.
• the invention also relates to a motor vehicle with a roof of the type described above.
