Embodiment Construction

[0026] figure 1 and 2 Two different embodiments of the sensor device 10 according to the invention are shown. Both sensor arrangements 10 have in common that they each have a first sensor 20a and a second sensor 20b. In addition, each sensor 20a and 20b is equipped with a first processor 50a or a second processor 50b, respectively. Each sensor 20a also has a first transmitting antenna 24a or a second transmitting antenna 24b. Each sensor 20a and 20b is also equipped with three first receiving antennas 26a or three second receiving antennas 26b, respectively. All antennas are in contact with either the first signal generator 22a or the second signal generator 22b.

[0027] exist figure 1 and 2 In both embodiments of the sensor device 10, at least one reference clock generator 30 is provided. The reference clock generator is in signal communication connection with the first signal generator 22a and the second signal generator 22b. A common reference clock is supplied or ...

Abstract

The invention relates to a sensor device (10) for monitoring the surroundings of a vehicle (100), comprising at least two sensors (20a, 20b), each having at least one signal generator (22a, 22b), a transmitter Antenna (24a, 24b) and at least two receiving antennas (26a, 26b), characterized in that at least one reference clock generator (30) is provided as a signal generator for the at least two sensors (20a, 20b) (22a, 22b) Generate a common reference clock.

Description

technical field [0001] The invention relates to a sensor device for monitoring the surroundings of a vehicle and a method for monitoring the surroundings of a vehicle by means of the sensor device. Background technique [0002] Sensor devices are known for monitoring the surroundings of a vehicle, for example for monitoring the side and rear areas of the vehicle. Such monitoring is usually carried out by means of electromagnetic signals, especially in the form of radar signals. Two sensors are often used when monitoring the rear of a vehicle or monitoring the sides of a vehicle. The sensors are often mounted on both transitions of the respective side of the vehicle to the rear of the vehicle, so that the sensors can monitor the respective sides of the vehicle as well as the region of the rear of the vehicle. The two sensors are connected to each other and are designed as master or slave sensors. This means that one of the two sensors has a common function as a master sens...
