Description

[0001] The invention relates to a system for masking vehicle vibrations perceived by a vehicle user. Furthermore, the invention relates to a method for masking vehicle vibrations using such a system.

[0002] Driving over uneven surfaces can be extremely annoying for vehicle users, leading to a loss of comfort and a negative driving experience. In connection with driving over uneven surfaces, it is known from DE 10 2021 214 131 A1 that gear changes while driving over the uneven surfaces are performed in order to mask or conceal the loss of comfort due to an impending gear change. However, the loss of comfort due to the vibrations of the uneven surface still persists.

[0003] The object of the invention is therefore to provide a system for masking vehicle vibrations which avoids the above-mentioned disadvantage in a simple and cost-effective manner.

[0004] This object is achieved according to the invention by providing a control device, at least one acceleration sensor for recording the vehicle vibrations, and at least one vibration-generating element, wherein the vibration-generating element can be controlled by the control device depending on the vehicle vibrations. The psychological concept of masking (masking) is utilized here to easily generate an improved comfort experience.

[0005] This particularly advantageously affects a user component, such as a steering wheel, a headrest, a vehicle seat, a belt element of a safety belt assembly, and / or an accelerator pedal. This allows the masking to have a direct effect on the vehicle user. The vibration-generating element can be integrated into a massage arrangement in a particularly advantageous manner.

[0006] In a particularly advantageous embodiment, the at least one acceleration sensor is provided on a body part in the area of ​​a vehicle interior. This allows the vibrations that actually affect the vehicle user due to an uneven road surface to be detected.

[0007] The object is also achieved by a method for masking vehicle vibrations by means of such a system, wherein in a first step the acceleration sensor detects a vehicle vibration and transmits it to the control device, in a second step at least one vibration generating element is triggered by the control device and in a third step the masking by the vibration generating element is ended by means of the control device when the at least one acceleration sensor detects the end of the vehicle vibration.

[0008] The invention is explained in more detail with reference to a drawing, which shows: Fig. 1 is a schematic view of a motor vehicle before driving over an uneven road surface, and Fig. 2 a schematic view of a vehicle seat with a vehicle user.

[0009] Fig. 1 shows a schematic view of a motor vehicle 2 shortly before driving over an uneven surface 4, which causes vibrations 6 (see Fig. 2) that have a negative effect on a vehicle user 8. The motor vehicle 2 also has an acceleration sensor 10, which is provided here in the sill area 12 in the area of ​​a vehicle interior 14 of the motor vehicle 2.

[0010] In order to mask or conceal the unwanted vehicle vibrations 6, a control device 16 is provided, which is control-technically connected to the acceleration sensor 12 and at least one vibration-generating element 18, 20, 22, 24, 26. The vibration-generating element can be a steering wheel vibration-generating element 18 acting on a steering wheel 28, a headrest vibration-generating element 20 acting on a headrest 30, a vehicle seat vibration-generating element 22 acting on a vehicle seat 32, a belt vibration-generating element 24 acting on a belt element 34 of a safety belt arrangement 36, and / or an accelerator pedal vibration-generating element 26 acting on an accelerator pedal 38. All of the aforementioned components 30, 32, 34, 38 are so-called user components that are in direct contact with the vehicle user 8. The vehicle seat vibration generating element 22 can be integrated into a massage arrangement (not shown).

[0011] A method for masking vehicle vibrations 6 can now be described as follows. In a first step, the acceleration sensor 12 detects a vehicle vibration 6. The signal of the vehicle vibration 6 is transmitted to the control device 16, which, in a second step, triggers at least one vibration-generating element 18, 20, 22, 24, 26. In a third step, the masking achieved by the vibration-generating element 18, 20, 22, 24, 26 is then terminated by the control device 16 when the acceleration sensor 12 detects the end of the vehicle vibration 6.
