AI Technical Summary

Problems solved by technology

This use causes high static currents and power losses in motor vehicles, which lead to a continuous discharge of the vehicle battery
In the operating state of the vehicle, such a system with an actively operating electronic consumer or first unit leads to increased fuel consumption and thus increased emissions of pollutants

Embodiment Construction

[0020] figure 1 A block diagram of a device 1 for operating a first electrical unit 2 is shown. The electrical unit 2 is here in the form of a sensor module 3 which has a measuring device 4 and a processing unit 5 which processes the data of the measuring device 4 and which is here in the form of an integrated circuit. The sensor module 3 is used, for example, to acquire sensor data, and can be configured as, for example, a pressure sensor, a displacement transmitter, an angle transmitter, and the like.

[0021] Furthermore, the device 1 has a rechargeable energy store 6 , which is designed as a capacitor in the exemplary embodiment. The device 1 also has a control unit 7 which is connected to the energy store 6 and the processing unit 5 . Optionally, the control unit 7 is also connected to the processing device via a decoupling circuit 8 (here only marked with dashed lines). Furthermore, device 1 has a second electrical unit 9 , which is designed as a control device 10 and...

Abstract

The device (1) has an interface (11) connecting a first electrical unit (2) i.e. sensor module (3) and a second electrical unit (9) i.e. control apparatus (10) together to supply energy to the first electrical unit by the second electrical unit. The first electrical unit comprises a rechargeable energy storage unit (6) i.e. capacitor, and a control unit (7) controls the device such that the interface supplies the energy to the energy storage unit from the second electrical unit in a first operating mode and transmits information in a second operating mode. An independent claim is also included for a method for operating first and second electrical units.

Description

technical field [0001] The invention relates to a device for operating at least one first electrical unit, in particular a sensor module, having a second electrical unit, in particular a control device, connectable / connectable to an energy source, wherein the first unit and The second units are connected to each other via an interface, in order to supply energy to the first unit via the second unit, and in order to transfer information at least from the first unit to the second unit. [0002] Furthermore, the invention relates to a corresponding method for operating at least one first electrical unit. Background technique [0003] Devices and methods of the type mentioned at the outset are known from the background art. Modern vehicles, in particular motor vehicles and motorcycles, have regulating systems which carry out regulation on the basis of sensor data, for example increasing or reducing the braking force in the context of ESP systems. Accordingly, the system requir...
