Problems solved by technology

However, these solutions are technically complex and, due to ultrasonic or vibrational loading, at least with regard to the durability of the solder joints and other mechanically sensitive parts, damage to the sensitive electronics of the sensor module with respect to the overall lifetime should be feared, which in turn reduces the Expectations regarding the overall lifetime of vehicle sensor modules at other locations
Solutions with complex external accessories such as wiper devices are also disruptive in view of the aerodynamics of the vehicle with the installed sensor modules

Embodiment Construction

[0080] exist figure 1 A vehicle sensor module 2 according to the invention is shown in . The vehicle sensor module comprises a sensor 3 which is fixedly arranged behind the cover 1 and a module housing 5 . The sensor 3 may be an optical sensor (eg a camera). Preferably, it is a radar sensor, especially a LiDaR sensor. Two or more sensors 3 can also be arranged in the vehicle sensor module 2 , wherein the sensors 3 can include emitters, receivers, light sources, scanners, movable laser control devices (in particular mirror systems or micromirrors). The module housing 5 is preferably of fixed design and forms a ring-shaped protection for the sensor 3 that is closed around the interior and has a recess or recess that is at least as large as the radiation path of the sensor. Arranged in the module housing 5 so as to completely cover at least this viewing window recess of the module housing 5 is a cylindrically shaped cover plate 1 arrangement, which in the sectional view descri...

Abstract

The invention relates to a cover (1) for a vehicle sensor module (2) for protection against environmental influences, wherein the vehicle sensor module (2) comprises at least the cover (1), an opticalor electromagnetic sensor (3) and a module housing (5), wherein the cover (1) is manufactured from a polymer material and has a region (4) through which the beam path of the sensor (3) passes, wherein the cover (1) has a rotationally symmetrical shape and is configured in such a way that it can be installed in the vehicle sensor module (2) in a manner mounted such that it can rotate relative to the sensor (3) and / or the module housing (5).

Description

technical field [0001] The invention relates to a cover for a vehicle sensor module for protection against environmental influences. Background technique [0002] Modern and especially future premium and mid-range vehicles are equipped with numerous driver assistance systems. These include, for example, optical cameras, medium- and long-range radar systems, ultrasonic sensors and light detection and ranging devices (LiDaR). These systems can also be summarized under the concept of ADAS (Advanced Driver Assistance System). Several of these systems are also already installed on some vehicles, and it follows from this that the number will increase. Most of these vehicle sensor modules are arranged as separate components at exposed locations on the vehicle body. These vehicle sensor modules usually have their own module housing, which includes at least one cover, which covers the sensor and the associated electronics from the outside. [0003] Sensor-based optical driver ass...
