Embodiment Construction

[0026] exist figure 1 and figure 2 The components of the first controller 10 are shown in . Control unit 10 is used in particular in a motor vehicle (not shown) as a component of a navigation system or a system for determining the position of control unit 10 . In this case, the controller 10 processes not only the signals transmitted to the controller 10 via a (high-frequency) antenna cable (not shown) as input signals, but also the sensors arranged inside the controller 10 (for example pressure sensors, yaw rate sensors, magnetic field sensors etc.) signal.

[0027] The first control unit 10 has a housing 13 formed from two housing elements 11 , 12 . The housing element 11 forms the housing base, while the housing element 12 is designed in the form of a cover or cap and in the connected state to the housing element 11 forms an interior space 14 for receiving two separate Circuit carrier 16,17. The housing element 12 has two flange-like projecting fastening sections 18 ,...

Abstract

The invention relates to a control unit (10; 10a to 10d) having a housing (13), which consists of at least two housing elements (11, 12; 61, 65, 72; 75), and having at least two circuit carriers (16;16a, 17; 17a; 64; 81, 82), wherein the first circuit carrier (16; 16a; 64; 81) is designed for accommodating at least one heat-generating component (1) and the second circuit carrier (17; 17a; 82) isdesigned for accommodating at least one sensor element (40, 41), wherein the two circuit carriers (16; 16a, 17; 17a; 64; 81, 82) are connected electrically to one another, and wherein the second circuit carrier (17; 17a; 82) is provided with vibration-damping means (45; 53, 54; 85), which serve to reduce vibrations transmitted to the second circuit carrier (17; 17a; 82) via the housing (13).

Description

technical field [0001] The invention relates to a controller as used in motor vehicle technology. The invention relates in particular to a controller for vehicle navigation or for automatic driving. In addition to the electrical and electronic circuit components, such a controller additionally has at least one sensor which, in conjunction with a satellite navigation system, is used to determine the position of the controller or the vehicle. Such sensors can be designed, for example, in the form of pressure sensors or magnetic field sensors and take advantage of the knowledge that the accuracy of determining the position or vector of an object solely by means of satellite-based navigation does not provide sufficient accuracy for many applications. Navigation without satellite navigation or satellite information only by means of rotational speed sensors and / or acceleration sensors provided in the vehicle or controller is also difficult to navigate to a destination. Precise pos...
