Embodiment Construction
[0069] figure 1 is shown here, for example, the front part of a side view of a left-hand drive vehicle 1 , in particular a tractor of a tractor-trailer combination, which has a vehicle driver for carrying out an object 4 according to a preferred embodiment of the invention. warning device2.
[0070] The device 2 comprises a sensor device 6 with a detection area 8 extending at least from a front detection area 12 arranged in front of the vehicle front 10 to a side detection area arranged laterally, here on the right vehicle side 14 16. In addition, the detection area 8 also includes a tail detection area 18 behind the vehicle rear portion 20, which extends from the rear end of the side detection area 16 to the end of the tail detection area 18 away from the side detection area 16 ( figure 2 ).
[0071] The detection region 8 is shown here as an idealized rectangle, but can also have any shape depending on the type of sensor device 6 . The sensor device 6 detects a stationa...

The invention relates to a device for warning a vehicle driver of a vehicle (1) about an object (4), containing a sensor apparatus (6), which has a front sensing region (12) and a side sensing region(16), a control apparatus (30), which interacts with the sensor apparatus (6) and which is designed to evaluate the signals from the sensor apparatus (6) for objects (4) standing or moving within thesensing region (8) and to define a warning region (A_info), which can be varied dynamically at least in accordance with the speed (v_ego) of the vehicle (1), and a warning apparatus (32), which is controlled by the control apparatus (30) in such a way that the warning apparatus produces a warning signal for warning the vehicle driver only if an object (4) is sensed in the dynamically variable warning region (A_info) by the sensor apparatus (6). According to the invention, the sensor apparatus (6) is also arranged and designed in such a way that the sensing region (8) continues from the side sensing region (16) into a rear sensing region (18) behind the vehicle rear (20) including the rear sensing region (18), and the control apparatus (30) is also designed to extend the dynamically variable warning region (A_info) in the direction of the longitudinal center axis (34) of the vehicle (1) into the rear sensing region (18) if an object (4) is sensed in the rear sensing region (18) by the sensor apparatus (6) and / or into the front sensing region (12) if an object (4) is sensed by the sensor apparatus (8) in the front sensing region (12), if the sensor apparatus (6) senses that the vehicle (1) and the object (4) are moving toward each other.
Description
technical field [0001] The invention relates to a device for warning a vehicle driver of a vehicle of an object according to the preambles of claims 1 and 8 and a vehicle with such a device according to claim 20 . Background technique [0002] In such a warning device, it is desirable to warn the object detected by the sensor device only when there is a dangerous situation in consideration of the driving situation, otherwise the driver will be disturbed by the unnecessary frequent generation of warning signals. Willingness to accept the device decreases. [0003] A device of this type is known, for example, from DE 10 2009 041 555 A1. This prior art describes a dynamic range limitation of the detection range for corner assist and dead-spot assist. In particular, this prior art describes a dynamically changing lateral warning field as a function of the speed of the vehicle viewed in a direction perpendicular to the side of the vehicle. The dynamic side warning range extend...
