Problems solved by technology

However, here, for example, the very high angular separation capability due to the physically possible large aperture when using several radar sensors Section of information no longer used
In the case of designs where coupling without the sensor should work, the signal output may suffer from phase noise
Currently, the distribution of line connections for high-frequency signals at 77 GHz appears difficult to use for sensor synchronization

Abstract

A sensor system (10) for a vehicle (F), including a control unit (SE), which is situated in the vehicle (F); multiple sensor units (Si1, Si2, Si3, Si4, Si5,...,Sin), which are situated on or in the vehicle (F) and connected to the control unit (SE), at least one of the sensor units (Si1, Si2, Si3, Si4, Si5,...,Sin) being connected via a bidirectional connecting line (VL) for signal exchange or viaa bidirectional connecting line (VL) and via a synchronization line (SL)to the control unit (SE) and being configured to receive a synchronization signal (SG) from the central control unit (SE) via the bidirectional connecting line (VL) or via the synchronization line (SL) to be operated by the control unit at a predefined point in time.

Description

Technical field [0001] The invention relates to a sensor system for a vehicle and a method for operating the sensor system for a vehicle. Background technique [0002] The current sensor system used to detect the surrounding environment of the vehicle (for example, objects within a certain angle range) usually includes an antenna or a sensor, through which the measured signal can be transmitted to the control device in the vehicle. It is known to operate multiple sensors simultaneously, coupled or even coherently. In the case of a sensor system used in a driving assistance system, an inexpensive sensor device is often important. However, in terms of highly autonomous driving, much higher requirements are placed on the sensing device. In addition, more and more sensors are used in vehicles, where the information from these sensors can be correlated in the central control device. At present, by coupling the sensors on the clock plane, it has been possible to realize the combinab...
